- Q: What do you mean, handle, butterfly valve, hard back and soft back?
- The butterfly valve of the handle butterfly 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 between 0 degrees -90 degrees, when rotates to 90 degrees, the valve is fully open. This valve is mounted horizontally.Butterfly valve has an elastic seal and metal seal two types of seals. Resilient sealing valve. The sealing ring can be mounted on the valve body or attached to the periphery of the disc.The hard back is the metal seal, and the soft back is the elastic seal.
- Q: The difference between butterfly valve and gate valve
- Its varieties and quantities are still expanding, and the development of high temperature, high pressure, large caliber, high sealing, long life, excellent regulation, as well as multi-function development of one valve. Its reliability and other performance indicators have reached a high level. Disadvantages, there is a certain resistance to the medium. Gate valves are more used in steam pipes and large diameter water supply pipelines, because of the general requirements of fluid resistance is small, the use of gate valve. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open. Need a higher installation space, the valve sealing surface has a certain self sealing capacity, its spool by the media pressure closely with the valve seat sealing surface contact, to achieve tight leakage.
- Q: What is an electric two position butterfly valve?
- It's an electric valveProduct brief:??Electric double position butterfly valve, this product is connected with flange type, clip type. Material: cast iron, carbon steel, stainless steel, 304/316Product overview???Electric double position butterfly valve (soft seal) is suitable for temperature less than 200 DEG C, adjust the flux and closure of the role of the medium nominal pressure is less than 1.6MPa of food, medicine, chemical, petroleum, electric power, textile, papermaking, water supply and drainage, gas pipeline. ?main features1 reasonable and novel design, unique structure, light weight, rapid opening and closing.2 operating torque is small, easy to operate, saving smart.3 can be installed in any position, convenient maintenance.4 seals can be replaced, reliable sealing performance to achieve two-way seal zero leakage.5 sealing material aging resistance, corrosion resistance, long service life etc..Electric double position butterfly valve adopts standardDesign standard: GB/T12238-1889Flange size: GB/T9113.1-2000; GB/T9115.1-2000; JB78Length: GB/T12221-1889Pressure test: GB/T13927-1992; JB/T9092-1999
- Q: How does the pneumatic butterfly valve control the angle of opening?
- This is really not good, control seems to be pneumatic defects, can only rely on the feeling
- Q: My bike has now 6200 miles on the odometer. The manual says that a valve adjustment should be performed every 6000 miles. But the bike runs fine. Can I just have the valve checked or should I have them adjusted even though the bike is fine? What will happen if I just keep riding it?
- First off you are suppose to take your bike back to have your valves adjusted after 500 miles. Anything later can cause problems. The motor is already broken in. why did you wait so long to have them adjusted ? Your vibration is the tire is not balanced right , take it else where. good luck
- Q: Fire signal butterfly valve what role?
- Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points
- Q: Butterfly valves are widely used in 2.0MPa below the pressure and temperature of not more than 200 degrees of various media, right?
- 3. kinds of butterfly valve:According to the connection mode: flange type, clip type.According to the material of sealing surface, soft seal and hard sealing.According to the structural form, butterfly valves can be divided into the following types:Plate typeInclined plate typeOffset plateLever type4. butterfly valve features:(1) the structure is simple and the shape is small. The utility model has the advantages of compact structure, short structural length, small size and light weight, and is suitable for large caliber valves.(2) the resistance of the fluid is small, and when the valve is fully opened, the valve seat passage has an effective circulation area, so the fluid resistance is smaller.(3) open and close, convenient and quick, good adjustment performance, butterfly plate rotation 90 degrees can be completed headstock. By changing the angle of rotation of the disc, the flow can be graded.(4) the opening and closing moment is smaller, because the butterfly plate on both sides of the rotating shaft is basically equal to the medium, and the opposite direction of the torque is generated, so that the opening and closing is more labor-saving.(5) low pressure sealing performance, sealing surface materials generally use rubber, plastic, sealing performance is good. Limited by the material of the sealing ring, the pressure and the temperature range of the butterfly valve are smaller. But the use of hard sealing butterfly valve pressure and temperature range has been greatly improved.
- Q: When i waa replacing the valves in the las 4 valves , they dropped and i dont know how to make them go back up, and i dont want to take the engine out of the car, is there any tool to make the valve go back up or there is any way to do it?? People told me that i can crank it by and , but i dont know how to do it where do i have to do it, i need help please im begging for help!
- Engine dis-assembly is now required .
- Q: i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?
- 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.
- Q: What's the meaning of butterfly valve d371po?
- According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve3== transmission: worm gear7== connection mode: clip type1== structure: midlinePo== sealing surface material: lining PoPo== propylene oxide (PO)
