3. Feature:
This valve is mainly composed of body, butterfly plate, valve shaft, seat and transmission devices. Simple and compact structure, small portable, convenient for transport, install and dismantle. 90 degrees of opening and closing, switch quickly, operating is small, light energy; Sealing performance is good, service life is long, can achieve zero leakages. Flow curve tending to straight line, excellent regulation performance.
Electric actuators can be divided into basic, overall switch model, external regulation as a whole. Electric device can provide or customer designated brand.
4. Sealability:
The valve for rubber seal, closing butterfly plate and seat sealing performance is good, two-way sealed good performance and the torque is small. the friction is very small between butterfly plate and the seat seal. The valve shaft drive the butterfly plate, butterfly plate do 90 degrees rotation. Butterfly plate flexible for opening and closing, no card acerbity, beating phenomenon, small torque.
- Q: My caravan is a bit sluggish on the pick up, I replaced the wires/plugs and the electronic distributor(I think thats what it is..). still a bit sluggish. Should i look at the valve gasket? Or fuel filter, or fuel pump next? 03 caravan sport 3.3L
- the valve pan gasket won,t cause it but the fuel filter will if it,s starting to clog up and also the cat nverter !
- Q: I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve
- Water should be off to the sink is the stop valve off
- Q: Are fire fighting signal valves and signal butterfly valves the same thing?
- The same nature: both can open and close, there is also information back fed.Signal valves are collectively referred to as signal butterfly valves.
- Q: Where are the exhaust valves, mud valves and butterfly valves?
- Chemical plant with colloid, puffed agent and granule. Wine industry, paper industry. Butterfly valves are used in petroleum, chemical, food, pharmaceutical, textile, water and electricity, ships, urban water supply and drainage, smelting, and energy systems as regulating and intercepting devices.
- Q: What does butterfly valve do?
- 5, connections are flanged, wafer connections, welded connections and lugs on the clip connection. ?Drive in the form of manual, worm gear, electric, pneumatic, hydraulic, electro-hydraulic linkage actuator, can realize remote control and automation.Advantages of butterfly valves1, opening and closing convenient, fast and labor-saving, fluid resistance is small, you can often operate. ?2, simple structure, small volume, light weight. ?3, to transport slurry, accumulation of fluid in the pipe outlet at least. ?4, under low pressure, can achieve a good seal. ?5, good regulating performance.Disadvantages of butterfly valve1, use pressure and working temperature range is small. ?2, poor sealing. ?Butterfly structure can be divided according to the bias plate, vertical plate, inclined plate and lever type. According to the form of sealing can be divided into soft sealing type and hard sealing type of two. The soft sealing type usually adopts rubber ring seal, and the hard sealing type usually adopts metal ring seal. ?By connection type can be divided into flange and clamp connections; press can be divided into manual transmission, gear transmission, pneumatic, hydraulic and electric types.
- Q: What are the butterfly valves models?
- Sealing surface material score:(1) soft sealing butterfly valve.1) the sealing pairs are made of non-metallic soft materials, which are made of non-metallic soft materials.2) the sealing pair is made of metal hard material and is made of non-metallic soft material.(2) metal hard sealing butterfly valve. The sealing pair is made of metal hard material and is made of metal hard material.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.
- Q: How do hydraulic butterfly valves work?
- Butterfly valve hydraulic drive device working principle1. manual operationWhen the hydraulic system suddenly fails, the valve can not move when the butterfly plate at any stop. Then, shaking the manual device, the guide block guide block in front of the manual shaft together with the driving shaft end, the cogging and drive shaft spline manual corresponding to the slot. Then, by dialing the driving device, the dial is shifted to the left end, and the transmission spline is connected with the manual shaft by a gear sleeve (the driving device is provided with a limit for preventing the tooth sleeve from jumping up), and the crank is disengaged from the hydraulic cylinder to disengage the hydraulic cylinder. Then turn the manual device and use the manual device to realize the disc movement.2. hydraulic operationWhen the hydraulic system returns to normal operation, the actuating device needs to be operated by hand. First, adjust the hydraulic cylinder to its initial state (0 digits) or at any position. Then manually adjust the opening of the disc to the position corresponding to the cylinder stroke (by observing whether the mark on the gear sleeve is in accordance with the mark on the crank, and judge the position of the disc and the cylinder). Then pull the gear sleeve and engage the spline on the crank by poking the driving device. Then fix the shift to prevent jumping. At this point, start the hydraulic system to restore fluid flow.
- Q: 19 years ago i had a valve repair and now im due to have heart valve replacement. I heard that the metal valve make noise has anyone who has had the metal valve have this type f problem or any other problem with the metal valve it would be a great help if anyone could answer
- tissue valve is better because you will need long term warfarin with metal one. metal ones have other drawbacks like amaemia too
- Q: Which is expensive, butterfly valve?
- The same material and caliber, butterfly valve structure is simple, less wood, the price is much lower than the gate valve, especially for clip type butterfly valve.
- 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
