- Q: When will Butterfly Valves be used?
- Butterfly valve has the advantages of simple structure, easy operation, small footprint and light weight;1, for the city water supply network in general, DN300 still DN300 valve, butterfly valve above, this installation is convenient (especially large diameter valve installation is inconvenient, the weight of large volume, big);2, there are sediment pipeline, such as powder, mud and other mixed substances;
- Q: Transformer butterfly valve and pressure relief valve difference
- The butterfly valve is usually fitted with an oil immersed transformer between the tank and the radiator to control the flow of oil between the transformer tank and the heat sink. When large power transformers are delivered, the radiators are usually individually packed to reduce transport sizes. The butterfly valve is closed to prevent the outside air or water from entering the transformer tank. When the transformer is transported to the installation site, the radiator is installed on the butterfly valve one by one. When the radiator is installed, the butterfly valve can be opened so that the oil flow between the transformer, the oil tank and the radiator can be circulated, so as to play the role of heat dissipation.When the transformer is running, it is found that when the radiator has seepage, the butterfly valve can be closed to avoid further leakage of transformer oil, and a new radiator can be replaced.
- Q: What does "10" in the butterfly valve "D71X-10" mean?
- The pressure of 10 kg 1.0MPA is usually cast iron
- Q: What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
- 1, the drive mode is different (handle or turbine), mainly based on the size of the valve and the opening and closing torque to decide.2. The butterfly plate of the worm valve is installed in the direction of the diameter of the pipe. In the butterfly valve body cylindrical channel, the disc shaped butterfly plate revolves around the axis, the rotation angle is 0 degrees ~90 degrees between, when rotates to 90 degrees, the valve opens the card completely.3, clip type butterfly valve is to use double headed bolts to connect the valve between the two pipe flanges, flange butterfly valve is a valve with a flange, bolt with the valve flange at both ends connected to the pipe flange.
- Q: How do you draw the butterfly valve in the engineering drawing?
- There is one of the most stupid way: find a picture of the butterfly valve, insert into the CAD, and then follow the trace, and there is a lot of CAD on the network of butterfly valve, yourself down..
- Q: In the pipeline attached building Atlas 05S502, in the middle of a water meter and check valve, the two sides are divided into two butterfly valve, want to ask why to arrange this way, what is the role of the two butterfly valve?
- Check the water gauge and check valve on both sides to facilitate the maintenance and replacement of water meter and check valve.
- Q: How is the lug butterfly valve connected to the flange?
- Lug type butterfly valve is also called a single flange type, that is, with a flange on the valve body, usually installed at the end of the pipe, and even the method is 1: double bolt lock on the valve body 2: into the flange 3: lock nut
- Q: What are the butterfly valves models?
- Sealing surface material score:(1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material.According to the form of sealing:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. The pressure of the valve seat, seat, or plate is produced when the seal is closed by the pressure from the valve.2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft.(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate.(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium.
- Q: I was wondering if someone could tell me the manufacturing date on this aircraft engine valve.
- Wow Hannah! That's a cool find for sure! It appears to be possibly a valve for a radial aircraft engine as it looks very similar to ones i've seen used in Pratt+Whitney R3350's etc. It looks like it could probably date to the 1940's up thru the 1950's. Look for a Part Number stamped on the valve or on the box. After WW2 there were all kinds of manufacturers making parts for airplanes. Many were gobbled up by competitors, converted to manufacturing other products or went out of business altogether. However, a few did hang on....and I think this may be what has become of Thompson Aircraft today.... Thompson Aerospace, Inc 22431 Antonio Parkway B160-102 Rcho Sta Marg, CA 92688-2804
- Q: Which is expensive, butterfly valve?
- The same material and caliber, butterfly valve structure is simple, less wood, the price is much lower than the gate valve, especially for clip type butterfly valve.
