Brief Introduction of Pneumatic Cast Iron Wafer Butterfly Valve:
Butterfly valve is mainly consisted of body, stem, disc, seat and driver(lever, gearbox, pneumatic and electric Actuator) and so on.
On off and controlling flow of valve are made by turning stem and disc together.
Suitable Medium:Water, sewage,sea water, air, foodstuff, oil etc.
Operator:Suitalbe for handles(dn50~300), gear operators, electric and pneumatic control actrators
- Q:Using a valve spring compressor
- the forked end of it will go over the spring part and the solid will work on the valve ,you can only use this one if the head is off though,the smaller ones work good if the head is still on the car,the c-clamps style though is the best one to use its safer and wont allow the springs to fly off,good luck.
- Q:CAD drawing of butterfly valve
- Your question is very international. Ha-haThis method of painting is not clear in one or two words.First you'll know the map, then you'll use CAD, so the two will add up.Guess you will.
- Q:What's the size of the signal butterfly valve sleeve?
- The signal valve of the fire door (not in the signal valve shutter doors, fire signal valve use: top fire signal butterfly valve with the valve opening and closing signal device, when the valve is closed by 25% (open degree 4/1), the signal device output signal was mistakenly closed to the fire control center. Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system.
- Q:What does "10" in the butterfly valve "D71X-10" mean?
- Represents the nominal pressure, refers to the 10MPa pressure butterfly valve, Zhengzhou butterfly valve factory specializing in the manufacture.
- Q:Butterfly valve in use when should pay attention to what problems?
- After the last in the pneumatic butterfly valve after use, also need to be cleaned immediately after the valve is closed, should use soft cloth to clean the valve, which may have some impurities, dirt removal, and oil lubrication, so it can better guarantee the use of the next.
- Q:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
- One is the turbine drive and the other is with the handle
- Q:What is the principle of butterfly valve and check valve? Any difference?
- Crown valve pressButterfly valve is butterfly valveThe check valve is a check valveButterfly valve is mainly switching functionThe check valve mainly stops the pipe from flowing backwardsThe two can only be said to be valvesThe others are different
- Q:How to control the single acting pneumatic butterfly valve?
- Single acting pneumatic butterfly valve can be divided into gas open type and gas closed type, which is usually called "normally closed" and "normally open". This is very critical. The single feature pneumatic butterfly valve is the biggest feature of its spring reset function, when the loss of gas or sudden failure, you can automatically restore the original state. So it's important to open the air or air this time.
- Q:What kinds of butterfly valves are available? What is the working principle of butterfly valves?
- 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.Divided by work pressure:(1) vacuum butterfly valve. Working pressure is lower than the standard atmospheric pressure butterfly valve.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa.
- Q:anti siphon valve?
- If the antisyphon valve is not leaking maybe you should focus attention on the main valve ( assuming it is a solenoid valve) to see if it closes completely. Another thing, if the irrigation zone is on an incline then the water in the system will drain to the lowest point. Sometimes it drains slowly causing the impression of a leaky feed valve.
