The Vacuum Valve Has The Adhering To Attributes:
The strain is decreased than atmospheric force, and the stress fall on the disc have to not exceed one kgf / cm2. The running temperature of the medium is dependent on the system in which the unit is employed. The temperature commonly does not exceed the assortment of -70 ~ + 150 ° C. The simple prerequisites for this kind of valve are to assure a superior degree of tightness in the connection and the tightness of the composition and gasket material. Vacuum valves can be divided into 4 teams in accordance to media force:
1) Small vacuum valve: medium stress p = 760 ~ 1mmHg
2) Medium vacuum valve: p = 1 × ten-3 mm Hg.
three) Large vacuum valve: p = one × ten-4 ~ 1 × ten-seven mm Hg
4) Extremely-large vacuum valve: p≤1 × 10-eight mm H
>Vacuum valve extensively made use of in the valve stem for linear movement of vacuum bellows globe valve. Gate valves are far more constrained, but for bigger diameters, ball valves, plunger valves and butterfly valves are also available. Plug valves for vacuum valves have not been promoted, simply because the plug valves need to have to be lubricated with oil, so that oil vapor might enter the vacuum procedure, which is not authorized. Vacuum valve closures are sealed with rubber or steel seals. The bellows of the bellows world valve are designed of stainless steel, superior zinc brass JI80, plastic and other materials. Tiny-diameter (diameter under 10 mm) globe valve closures can be sealed with a diaphragm. Very low and medium vacuum can use spherical plug valve
>The vacuum valve has the pursuing attribute
>The force is decrease than atmospheric stress, and the force drop on the disc have to not exceed one kgf / cm2. The operating temperature of the medium depends on the method in which the system is made use of. The temperature generally does not exceed the assortment of -70 ~ + a hundred and fifty ° C. The principal valves of Shanghai Shenhong Valve Co., Ltd. are: stress lessening valve (gasoline force lessening valve, adjustable force lessening valve, bellows lowering valve, piston cutting down valve, steam reducing valve, pilot lessening valve, air Tension lessening valve, nitrogen pressure decreasing valve, water strain decreasing valve, self-operated stress minimizing valve, proportional force cutting down valve), protection valve, thermal insulation valve, cryogenic valve, ball valve, world 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, Glove Box Accessories pneumatic valve, electric valve, significant force valve, medium Pressure valve, lower stress valve, hydraulic handle valve, vacuum valve, rubber lined valve, fluorine lined valve. The fundamental specifications for this style of valve are to make certain a substantial diploma of tightness in the link and the tightness of the construction and gasket produc
>Vacuum valve broadly employed in the valve stem for linear motion of vacuum bellows world valve. Gate valves are much more minimal, but for much larger diameters, ball valves, plunger valves and butterfly valves are also available. Plug valves for vacuum valves have not been promoted, mainly because the plug valves need to be lubricated with oil, so that oil vapor may well enter the vacuum program, which is not allowe
>Vacuum valve closures are sealed with rubber or metal seals. The bellows of the bellows globe valve are produced of stainless metal, large zinc brass JI80, plastic and other products. Modest-diameter (diameter below 10 mm) globe valve closures can be sealed with a diaphragm. Reduced and medium vacuum can use spherical plug valve
>The vacuum valve has the pursuing characteristics: The stress is reduce than atmospheric pressure, and the tension fall on the disc should not exceed 1 kgf / cm2. The working temperature of the medium relies upon on the approach in which the product is utilised. The temperature usually does not exceed the variety of -70 ~ + a hundred and fifty ° C. The basic necessities for this style of valve are to guarantee a significant diploma of tightness in the link and the tightness of the composition and gasket material.
