Currently in fine chemical industry, nuclear power industry, toxic, harmful media and nuclear power valves used in a lot of bellows bellows globe valve and gate valves. Bellows valve stem in the Department's Dynamic Sealing stuffing into the valve cover at the static seal, the valve must effectively Du medium leakage.
The valves; because of their need for stem headstock rotated 90 degrees along its own radial. Bellows can only bear tension and compression and can not afford to be reversed, thus resolving the direction of stem of the hoist has become the key to the design of bellows valve.
Product design and production of valves for many years practical experience, and the ball valve design concepts will stem the rise and fall, and toggle the sphere rotated 90 degrees combined organic solve this problem.
This valve structure is simple, open and close light, sealing reliability, long life. And the bellows and the bellows globe valve, like valve handwheel can just gently give Bellows Valve added a new species.
Bellows globe valve and bellows valve, due to structural reasons for that; valve flow coefficient is small, the energy losses. Bellows valve structure of the large body of high caliber at least more than double the size of stem followed a series of part size must be increased, and the stability of the valve is not good, is a last resort.
Lifting rod bellows valve can be seen as part of the pipe, valve flow coefficient, a slight energy loss, is the ideal valve components. And the same caliber as compared bellows globe valve (in 50 caliber, for example) cut-off valve flow coefficient ~ Cv is 40 ~ 60, while the valve's flow coefficient ~ Cv is 440, 7 ~ 10 times the energy savings are energy-efficient green products, can replace bellows globe valve. Plus, corrugated pipe ball valve can also be used.
