- Q: How do you explain A in butterfly valve D37A1?
- Represents a seal or lining material symbol.Said sealing ring or lining material with the Chinese phonetic alphabet: B Babbitts D nitrided steel, acid resistant stainless steel H, J L Aluminum Alloy, hard rubber, nylon NL, P leather, SA PTFE, SC PVC, SD bakelite, T copper, TC enamel, X rubber, Y hard alloy
- Q: Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
- Is the valve coming off a water supply line? if so, it's a needle valve probably installed at some point during a remodel or while adding an appliance. If it's on the cold side it will most likely go to a refrigerator ice maker or water dispenser, if it's on the hot side it may go to a dishwasher or other device that requires hot water.
- Q: Butterfly valve general use occasions
- Butterfly valve general use occasions:1 、 soft sealing butterfly valve applies to ventilation, dust removal pipeline two-way opening and closing and adjustment, metallurgy, light industry, power, petrochemical systems, gas pipelines and waterways.2, metal sealed double eccentric butterfly valve, suitable for heating, steam, water and gas, oil, acid and other pipelines, as the adjustment and closure devices.3, metal seal three eccentric butterfly valve, in addition to as large pressure swing adsorption gas separation control valve.4, metal seal three eccentric butterfly valve, can be widely used in petroleum, chemical, metallurgy, electricity, food, medicine, water supply and drainage, gas transportation and other fields.
- Q: What does the triplex of pneumatic butterfly valve mean?
- Upstairs is quite right, but now seems to use very little oil mist, and now generally referred to as "triple parts" as if: filter pressure reducing valve, solenoid valve, with the valve position feedback switch.
- Q: What are single eccentric and double eccentric in butterfly valves? What's the difference, please explain in detail?
- Eccentric butterfly valve is divided into single eccentric butterfly valve, double eccentric butterfly valve, three eccentric butterfly valve, variable eccentric butterfly valve.Single eccentric butterfly valve: extrusion problems, address concentric butterfly valve and valve seat of the resulting in a single eccentric butterfly valve, the structural characteristics of the stem axis deviated from the disc center, so that the butterfly is no longer a rotary bottom plate, axial dispersion, reduce the excessive squeezing and the lower end of the seat of the butterfly board.
- Q: Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
- One more 3 in D71X-10 stands for adding a worm gear to the valve. What are the same, the difference is driven by the handle into the drive, gear drive, worm gear drive for large caliber butterfly valve a little less, because the valve torque is big, big, hard to handle and can rotate, and if the worm, you can turn a few laps handwheel. If there are other questions, we can continue to ask questions, the city butterfly valve manufacturers
- Q: Butterfly valve model D373F-16C, ask God answers
- D - butterfly valve, 3 - turbine rotation, 7- clamp type, 3- eccentric F - sealing surface for PTFE sealing, 16- bearing pressure 16KG, C - body material cast steel
- Q: What is the butterfly valve
- Conclusion: Although the double valve advanced technology, metrology, but must ensure stable and timely flow of materials, in order to achieve good results, so the combination of flotation system and dual use of butterfly valve can fundamentally solve the flow and measurement of powder, so as to rely on self weight principle of materials, so we plant layout the middle of a large number of mechanical equipment to save not only, more important to reduce the cost of investment and running.
- Q: Whenever sports cars are referred, people talk in terms of 'valves'. ex: v8, v12 etc. What does this all mean? Also they sometimes say that a v8 makes a great noise. why? How does the number of valves effects the performance? Many thanks.
- When talking about car engines, references such as v4, v6, v8, v10 and v12 are not for the number of valves. it is for the number of cylinders. The more cylinders that an engine has, the more fuel it consumes and most of the time, the more horsepower it can make. There are exceptions to this though. Regarding the noise of the engine, i would agree that a v8 sounds very good when it is roaring. Valves are actually the openings for fuel to get into the cylinders and the exhaust to come out from. Most modern engines have two valves for incoming fuel and two valves for the exhaust making a total of four valves per cylinder. hope that clears it for you
- Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- Front is the same, there is C refers to the body of the material is carbon steel, without C, usually refers to gray iron (cast iron is more common, so are generally omitted)
