- Q: What do you mean, handle, butterfly valve, hard back and soft back?
- My understanding is: PTFE butterfly valve is a hard back; soft rubber seat is a soft back
- Q: Today saw the butterfly valve and butterfly valve, I do not know what is the difference between the two
- Butterfly valve is clear that the butterfly, because it is so called as valve plate, butterfly valve.
- 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: What does the butterfly valve model d344h, d345h, d346h, d347h mean?
- According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!
- 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: 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?
- if the valves are not chattering (WOrse then normal) and you havent lost power or gas milage, then no...dont get it adjusted and no ... your not hurting the bike.
- Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- D stands for butterfly valve. 71 represents the clamp type, X represents the sealing surface material, and 16 represents the valve to bear the pressure 1.6MPA, C position is the valve body material code, omitted to represent gray cast iron valve; C represents the valve body material is carbon steel.
- Q: Butterfly valve in the use of the difference? Caliber?
- Role of butterfly valveButterfly valve is to use disc type to open and close parts reciprocating reciprocating about 90 degrees to open, close or adjust the flow of medium valve. The butterfly valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, the driving performance of torque is small, simple operation, rapid, high chemical corrosion, and can also have good flow control function and closure characteristics, the use of butterfly valve is very extensive. 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. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
- Q: The difference between vertical and horizontal butterfly valves in municipal water supply
- Vertical and horizontal only installation directions and installation methods are different. Functionally, there is no difference.The main difference between the two methods of installation is that:1. horizontal can effectively avoid the high temperature radiation above the pipe. The disadvantage is that it takes up a lot of space.The advantage of the 2. vertical is that the occupation space is smaller, and it is easy to install. If the pipeline is higher, it is not convenient for maintenance.
- Q: 1988 volkswagon cabriolet, rabbit tried mystery oil let sit for a week having trouble with stuck valves even taken a wrenrch to manually unstick. help any suggestions 4 cyclinder car has been sitting up for about 4 years
- The only reason for a stuck valve is if it bent from a thrown timing belt. Sitting 4 years will not cause valves to stick usually, because there is always some oil leakage from the head, that prevents rust. How do you know the valve is stuck? Have you done a compression test, checked the valve clearance? When you say you take a wrench to manually unstick it, it would help to know what you mean, because there is no place to put a wrench that would help unstick a valve that was stuck. You need to tell us much more.
Our valve is widely used in petroleum, chemicals, power, metallurgical, pharmaceutical and other industries.Our campany insists on surviving on high quality, creating with science and benefiting from management.
