Vacuum Valve Purpose

Posted by [email protected] on
The vacuum valve has the adhering to attributes:

The stress is lower than atmospheric force, and the strain drop on the disc have to not exceed 1 kgf / cm2. The working temperature of the medium depends on the approach in which the unit is utilised. The temperature usually does not exceed the variety of -70 ~ + a hundred and fifty ° C. The simple specifications for this kind of valve are to ensure a large diploma of tightness in the link and the tightness of the construction and gasket content. Vacuum valves can be divided into four teams according to media strain:

1) Low vacuum valve: medium force p = 760 ~ 1mmHg

two) Medium vacuum valve: p = 1 × 10-three mm Hg.

3) Large vacuum valve: p = 1 × 10-4 ~ one × 10-seven mm Hg

4) Extremely-high vacuum valve: p≤1 × 10-eight mm Hg.

Vacuum valve widely utilized in the valve stem for linear motion of vacuum bellows world valve. Gate valves are a lot more restricted, but for more substantial diameters, ball valves, plunger valves and butterfly valves are also accessible. Plug valves for vacuum valves have not been promoted, due to the fact the plug valves want to be lubricated with oil, so that oil vapor might enter the vacuum method, which is not allowed. vacuumfittings are sealed with rubber or metallic seals. The bellows of the bellows globe valve are made of stainless steel, higher zinc brass JI80, plastic and other resources. Little-diameter (diameter underneath ten mm) globe valve closures can be sealed with a diaphragm. Minimal and medium vacuum can use spherical plug valves.

The vacuum valve has the adhering to qualities:

The force is lower than atmospheric pressure, and the force drop on the disc must not exceed 1 kgf / cm2. The running temperature of the medium relies upon on the procedure in which the unit is employed. The temperature normally does not exceed the variety of -70 ~ + one hundred fifty ° C. The main valves of Shanghai Shenhong Valve Co., Ltd. are: stress minimizing valve (fuel force lowering valve, adjustable force lowering valve, bellows lowering valve, piston minimizing valve, steam lowering valve, pilot reducing valve, air Pressure minimizing valve, nitrogen pressure minimizing valve, drinking water stress reducing valve, self-operated strain lowering valve, proportional strain decreasing valve), safety valve, thermal insulation valve, cryogenic valve, ball valve, globe valve, gate valve, check out valve, butterfly valve, filter System, discharge valve, diaphragm valve, plug valve, plunger valve, equilibrium valve, regulating valve, lure valve, pipe clamp valve, blow down valve, exhaust valve, mud discharge valve, pneumatic valve, electric valve, higher strain valve, medium Strain valve, minimal force valve, hydraulic manage valve, vacuum valve, rubber lined valve, fluorine lined valve. The basic demands for this sort of valve are to make sure a higher degree of tightness in the relationship and the tightness of the construction and gasket material.

Vacuum valve commonly utilized in the valve stem for linear movement of vacuum bellows globe valve. Gate valves are a lot more constrained, but for more substantial diameters, ball valves, plunger valves and butterfly valves are also available. Plug valves for vacuum valves have not been promoted, since the plug valves require to be lubricated with oil, so that oil vapor may possibly enter the vacuum method, which is not authorized.

Vacuum valve closures are sealed with rubber or metal seals. The bellows of the bellows world valve are manufactured of stainless steel, higher zinc brass JI80, plastic and other supplies. Small-diameter (diameter under 10 mm) globe valve closures can be sealed with a diaphragm. Minimal and medium vacuum can use spherical plug valves.

The vacuum valve has the adhering to characteristics: The force is reduce than atmospheric force, and the stress fall on the disc must not exceed one kgf / cm2. The running temperature of the medium is dependent on the procedure in which the system is used. The temperature typically does not exceed the range of -70 ~ + one hundred fifty ° C. The standard specifications for this variety of valve are to guarantee a high degree of tightness in the link and the tightness of the structure and gasket content.
