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.
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: What's the difference between the three eccentric butterfly valve and the two eccentric butterfly valve?
- Double eccentric butterfly valve refers to: valve plate and central axis partial, simply said that there are two parts of the butterfly valve.Three eccentric butterfly valve, there are three places are biased
- Q: Does the wet alarm valve group need to install the signal butterfly valve?
- two is the sprinkler system is not allowed inside water, when the butterfly is closed, will transmit a signal to the the fire alarm system, fire alarm system receives a monitoring signal (so called signal butterfly valve), fire sprinkler system that the floor is anhydrous state, fast repair.
- Q: Butterfly valve general use occasions
- Butterfly valve general use occasions:1 、 soft sealing butterfly valve applies to ventilation, dust removal pipeline two-way opening and closing and adjustment, metallurgy, light industry, power, petrochemical systems, gas pipelines and waterways.2, metal sealed double eccentric butterfly valve, suitable for heating, steam, water and gas, oil, acid and other pipelines, as the adjustment and closure devices.3, metal seal three eccentric butterfly valve, in addition to as large pressure swing adsorption gas separation control valve.4, metal seal three eccentric butterfly valve, can be widely used in petroleum, chemical, metallurgy, electricity, food, medicine, water supply and drainage, gas transportation and other fields.
- Q: Gate valve and butterfly valve which is installed when there is a direction?
- Do not require frequent opening and closing, and keep gate fully open or fully closed. Not suitable for use as a regulator or throttling.Butterfly valve refers to the closure of parts (butterfly plate) as the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually 90 degrees butterfly simple structure, small volume and light weight, only by a few parts. Moreover, the utility model can be rapidly opened and closed only by rotating 90 DEG, and the operation is simple.Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, gate valve advantages: fluid resistance is small, opening and closing more effort, medium flow unrestricted, not disturbing flow, do not reduce pressure.
- Q: What does the butterfly valve D361H - 25C DN350 mean?
- Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM
- 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: Specifically an engine valve retainer.
- Valve Spring Retainer
- Q: What is the national standard for clip butterfly valves?
- GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
- Q: Butterfly valve structure and working principle
- How it works: the disc is driven by the stem, and if it turns 90 degrees, it can be opened and closed once. By changing the deflection angle of the plate, the flow of the medium can be controlled. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve.
- 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.
