Start A New Life at the earliest possible !

We are the resident of Delhi a big metro city. It’s a beautiful city with wider roads, parks, malls, markets, hotels and every such thing which a resident requires. Metro added a big charm to it few years ago.

But the city has it’s own problems too. It has become the most polluted city of the world. We filed RTIs & the outcome was that the pollution levels in certain areas were even higher by 9 to 10 times from the prescribed limits. We arranged the lungs check up camps & found that almost 25% of the persons had mild or severe lung infections. The city has become a congested one also. The inflow of new vehicles has made it the world’s 5th most jammed city. It’s difficult to move easily even if one is in any kind of emergency. The city suffers during rainy season due to severe water logging and so on, the problems continue to rise.

Therefore, we were looking to START A NEW LIFE, a pollution free life, a green life, a healthy life. We were willing for a safe home, a green home where we can go & spend our time so that even while working in Delhi, we can be there on our weekends to feel better from others.

We checked various online websites related to property & found the https://housing.com/. It is an amazing website as it offers various opportunities. You can look for a rented home, PG or hostel facilities. You can buy or sell new homes. You can offer your property on rent. The site also exhibits amazing data of the New Projects from various locations in India with BHK & Budget options.

As we were looking for a healthy home, we checked the option of New projects & the whole lot of details opened in front of us from various cities. We clicked at Dehradun & OMG, we found so many construction sites, with budgetary details, pics & everything. It was amazing. Everything at a single go. Everything at a  single click. Almost 40 options with various budgets ranging from few lakhs to few crores, it had everything to offer.    35

It gave us almost every detail, from number of bed rooms to villa or apartment, to budget, to possession details, area details and everything that we may require to decide a project. We have downloaded their App too as it seems suitable.

We have now decided to take the BOLD decision to buy our home at Dehradun and we have selected a few options from the above website. Soon we are going there to view the location & to understand the technical advantages of every location & soon we will start a new life, a better life, a changed life, a healthy life, a desirable life with the help of https://housing.com/.


Please view the video embedded below to LOOK UP & to take a Bold & positive decision of your life.

Look up with Optimism with a hope for the future !

Japan was attacked with nuclear weapons on its two cities i.e. Hiroshima & Nagasaki. Entire world had assumed that Japan will be wiped out of the growth map. But people of Japan were optimistic. Inspite of the massive attacks on their two cities, inspite of deaths of scores of persons, inspite of the large scale devastation due to the nuclear attacks, it still raised its spirits with optimism and with a hope for the future. And the outcome is that Japan now stands amongst the top most countries of the world. The citizens of Japan get visa on arrival and that too, anywhere in the world. Every organization feels proud if it has an employee from Japan. This happened because people of Japan who faced massive attacks on its soul, could come out of the trauma & could raise their mind with optimistic thoughts. In the same way, we must have the positive & optimistic thinking if we want to achieve success in our life.

One of my friend got a big shock of his life when he got the Doctors report that his father had prostate cancer. It was really shocking for the entire family. The PSA was over 4 and it should be with in 2 for any normal person. The biopsy was done & doctors advised the bone scan. Biopsy and  bone scan reports disclosed that the cancer had already reached the bones & already at the third stage. The family was shocked on finding that his life was limited to a maximum of 12 months.

The entire family was shattered on this disclosure. Even we were shocked as it was never ever assumed that a normal looking person could be in such a dangerous stage and that too due to cancer. They all decided to not to disclose about the disease to the patient. They requested doctors concerned to not to reveal the disease to the patient even though everyone knew that it was a LOST BATTLE.   31

Many doses of Chemotherapy were given to him at various hospitals but   they never told him about the disease to the patient. Even though his life was said to be of a maximum of 12 months, the family had already crossed more than two years. After almost three years, the patient came to know that he was suffering from cancer but he was told that it was just the initial stage & so there was nothing to worry. The situation further deteriorated and the Radiation started. The situation was really bad. They knew that they can’t do any more for him and after almost four & a half years he expired.

The crux is that even though they knew that it was the lost battle, that he had a maximum life of 12 months, they still looked up with optimism and with a great hope. The combined optimistic behaviour of the entire family extended his life by almost four times i.e. upto 54 months.


Truly speaking it happened in our own family & the patient was none other than my Grand father who expired in 2008. So I will just say that let whatever happen, if you are optimistic, if you have positive thoughts, you can always look upwards. Please log on to the website  https://housing.com/lookup as it will teach you on how to look upwards in your life.

Butterfly Valve




with thanks : Jackie Chow

How & Why Are Butterfly Valves Used ?


A Butterfly Valve is used to control the flow of material through a circular pipe or tube. Typically the material is air, gas, steam, or liquid. Certain dry materials may also be handled through a butterfly valve.

Simply, a butterfly valve consists of a circular disc with its pivot axis at right angles to the direction material is flowing. The valve is made up of a body, seat, disc, stem, and actuator. Each component part is available in a variety of materials called “trim features.” Properly combining trim features to address material handled and environment is important in selecting the correct model valve for its intended service.

Body 
A butterfly valve body can be made of cast iron, ductile iron, aluminum, carbon steel, stainless steel and exotic metals. 

Butterfly valves are available in wafer and lug style. Wafer style valves are installed “sandwiched” between pipe flanges. This style of valve is easier to replace or install. However, replacing a wafer valve requires the conveying line to be drained. Once the valve is removed, there is nothing to seal material either upstream or downstream from the removal point.

Lug style valves contain tapped holes that allow them to be bolted directly to a mating flange. In the closed position, the valve independently seals material to the upstream and downstream side. Because of this independent sealing, lug valves may be used to isolate downstream equipment that may require replacement or maintenance.

Seat 
Resilient seated valves are the most commonly used types. The interior of the valve body is lined with an elastomer seat. Seats may be made of EPDM, buna, viton, Teflon, natural rubber, carbox, chlorbutyl, white buna, or white neoprene as well as other materials. Choice of seat material depends on temperatures, pressures and material handled.

The seats of some inexpensive butterfly valves are typically molded into the body and cannot be repaired or replaced. Precision butterfly valves typically contain removable seats that are repairable or replaceable.

Disc 
The valve disc (controlled by the actuator) regulates the flow of material within the conveying line. Disc materials are available to meet a variety of application demands: stainless steel, aluminum/bronze, ductile iron, ductile/epoxy coated, ductile/nickel plated, ductile/nylon II coated as well as others. As the disc is directly in the material flow stream, care must be taken in specifying the proper material of construction and disc shape. Some discs are designed to allow increased flow patterns through the piping.

Stem 
The stem passes through the center of the valve, attaches to the actuator, and positions the disc for material flow control and shut off. Depending on the application and valve size, stems may be one or two-piece construction. Typical materials of construction include carbon steel and different grades of stainless steel.

Actuator 
A variety of actuators are available for butterfly valves: manual handle, gear, pneumatic, electric and electro-hydraulic. Also, actuators that may be enclosed in special housings and buried are available for certain underground applications.

Other considerations 
Depending on the application, additional valve features that may need to be considered. Some of these features include: the manner in which the stem and disc are attached, the way the stem and disc assembly mount inside the valve body, undercutting of disc, type of material used in stem bushings and packing, and availability of a ring seal between the seat and valve body.

Working with a company that can offer and properly apply a variety of trim features will enhance the success of the butterfly valve in a specific application.

Applications

As stated earlier, Butterfly Valves are generally specified for most air, gas, steam, and liquid applications. They offer an excellent, economically priced, positive shut-off valve for handling materials (e.g. gases and liquids) that are easily displaced by the valve disc as it closes. When handling this type of material, butterfly valves provide a reliable, bubble-tight, bi-directional shut off.

Care must be taken when applying a butterfly valve in semi-abrasive or abrasive dry material applications (this includes slurry applications that contain suspended particles because: 
1) A valve disc closing on dry bulk material will create premature wear to the rubber seat. 

2) The obstructed orifice created by the disc may cause bridging of material on the inlet side of the valve. 

3) A disc opening or closing on a standing column of dry material may cause the material to jam / pack. 

4) Particles of dry material or suspended particles in slurries may become trapped between the disc and seat, causing conveying line inefficiencies.

Other Types of Butterfly Valves

As a person becomes familiar with butterfly valves, they will undoubtedly discover other types of butterfly valves on the market. Listed below is a brief introduction to some of these other types.

Inflatable Seated Butterfly Valves
Inflatable seated butterfly valves utilize an inflatable seat or bladder to create a seal around the disc. Once the disc is brought to the closed position, the bladder is inflated pneumatically.

Pros: 
1) Since the seal is created after the disc closes, less torque is required to move the disc into the closed position. A smaller sized actuator costing less money is can be used.

2) Again, because the seal is created after the disc closes, minimal abrasion exists between the disc and the seat.

Cons: 
1) In addition to the controls needed to verify the position of the disc, additional controls are needed to identify whether the bladder is inflated or not. These controls add cost to the valve.

2) The bladder may be damaged and not creating a seal, even though controls identify that a seal has been established.

3) The valve must be located near an air supply to pneumatically inflate the bladder. 

4) The inflatable bladder is subject to damage and abrasion, requiring periodic replacement.

High Performance -- Double Offset Butterfly Valve
This type of butterfly valve is ideal for applications involving higher temperatures (up to 1200º F) and higher pressures (up to 1440 psig). The disc and stem are double offset, causing the disc to “cam” into place upon closure.

Pros:
1) A reliable butterfly valve for handling higher temperature and pressure applications.

Cons:
1) Cost -- considerably more expensive than standard butterfly valves.


High Performance -- Triple Offset Butterfly Valve
This type of butterfly valve is often used in refinery and off shore applications where more extreme conditions exist. Most triple offsets utilize a metal on metal seat and disc closure, are rated up to 600# class, and are fire safe.

Pros:
1) A reliable valve for extreme applications.

Cons:
1) Cost -- more expensive than the double-offset butterfly valve.


The double and triple offset butterfly valves are specialized valves for extreme applications.

Salina Vortex Corporation manufacturers a variety of slide gates, diverter valves and iris valves for handling dry bulk material. Vortex butterfly valves are available for air, steam, liquid and certain dry material applications.
