- 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: Butterfly valve common faults and treatment methods?
- Three, summary:Only familiar with every detail of circulating water pump outlet valve and butterfly valve equipment, timely and thorough maintenance and strict debugging, to ensure the safety and reliability of equipment operation, to ensure the healthy and orderly operation of equipment.
- Q: What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
- For clip butterfly valves, there are no flanges at the ends of the butterfly valve. There are only a few guide bolts. The valve is connected with the end flange with a set of bolts / nuts.In contrast, the demolition to facilitate some of the lower cost of the valve, but the drawback is that a sealing surface problems, the two sealing surfaces have to be taken apart.Flange butterfly valve at both ends of the flange, and pipe flange connection. The seal is relatively more reliable, but the valve is of relatively high cost.
- Q: What is the medium flow rate when the centerline butterfly valve is fully open?
- After inspection, the product certificate shall be attached to the factory.Butterfly: also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow.
- Q: Butterfly valve is the control valve?
- The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
- Q: What is the effect of nylon coating on butterfly valve plate? Thank you
- Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
- 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: Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- Louzhu asked extremely, since it is hard seal, it is bound to guarantee long-term work after zero leakage, or should be configured double eccentric soft sealing valve is more reasonable.
- 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: What is the difference between wafer (flangeless) type and LUG type of butterfly valves?
- WAFER butterfly valve is the valve is divided into LUG (ears) with and without LUG, ordinary LUG without clip on 12 points in the direction of valve is generally two to four bolt holes was not, whereas the LUG of butterfly valve cross dispersed in a circle. Bolt hole. With LUG all bolted through the LUG, so that the butterfly valve and the clamp on the two flange connection is more solid, you check the valve picture, it is easy to understand
