The tension is lessen than atmospheric force, and the tension drop on the disc must not exceed one kgf / cm2. The running temperature of the medium depends on the procedure in which the gadget is used. The temperature normally does not exceed the assortment of -70 ~ + a hundred and fifty ° C. The basic needs for this sort of valve are to make sure a higher degree of tightness in the connection and the tightness of the framework and gasket materials. Vacuum valves can be divided into 4 groups in accordance to media tension:
1) Small vacuum valve: medium pressure p = 760 ~ 1mmHg
two) Medium vacuum valve: p = 1 × ten-3 mm Hg.
3) Significant vacuum valve: p = 1 × ten-four ~ one × ten-7 mm Hg
4) Ultra-significant vacuum valve: p≤1 × 10-8 mm H
>Vacuum valve greatly utilized in the valve stem for linear movement of vacuum bellows globe valve. Gate valves are more constrained, but for much larger diameters, ball valves, plunger valves and butterfly valves are also out there. Plug valves for vacuum valves have not been promoted, due to the fact the plug valves need to have to be lubricated with oil, so that oil vapor may well enter the vacuum method, which is not allowed. Vacuum valve closures are sealed with rubber or metal seals. The bellows of the bellows globe valve are created of stainless steel, higher zinc brass JI80, plastic and other components. Tiny-diameter (diameter under 10 mm) globe valve closures can be sealed with a diaphragm. Small and medium vacuum can use spherical plug valve
>The vacuum valve has the next attribute
>The strain is lessen than atmospheric tension, and the force fall on the disc must not exceed 1 kgf / cm2. The running temperature of the medium is dependent on the course of action in which the gadget is utilised. The temperature generally does not exceed the array of -70 ~ + one hundred fifty ° C. The key valves of Shanghai Shenhong Valve Co., Ltd. are: force lessening valve (gasoline force reducing valve, adjustable pressure reducing valve, bellows lessening valve, Glove Box Accessories piston lessening valve, steam reducing valve, pilot lessening valve, air Force lessening valve, nitrogen pressure reducing valve, water strain lowering valve, self-operated pressure decreasing valve, proportional force decreasing valve), basic safety valve, thermal insulation valve, cryogenic valve, ball valve, world valve, gate valve, examine valve, butterfly valve, filter Unit, 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 powered valve, significant tension valve, medium Force valve, minimal stress valve, hydraulic command valve, vacuum valve, rubber lined valve, fluorine lined valve. The fundamental prerequisites for this variety of valve are to guarantee a higher diploma of tightness in the link and the tightness of the framework and gasket material
>Vacuum valve greatly utilised in the valve stem for linear movement of vacuum bellows world valve. Gate valves are additional confined, but for larger diameters, ball valves, plunger valves and butterfly valves are also readily available. Plug valves for vacuum valves have not been promoted, simply because the plug valves will need to be lubricated with oil, so that oil vapor may perhaps enter the vacuum procedure, which is not allowe
>Vacuum valve closures are sealed with rubber or metal seals. The bellows of the bellows world valve are produced of stainless metal, substantial zinc brass JI80, plastic and other resources. Smaller-diameter (diameter beneath ten mm) world valve closures can be sealed with a diaphragm. Lower and medium vacuum can use spherical plug valve
>The vacuum valve has the pursuing characteristics: The tension is lower than atmospheric pressure, and the force fall on the disc have to not exceed 1 kgf / cm2. The working temperature of the medium relies upon on the course of action in which the unit is utilised. The temperature generally does not exceed the variety of -70 ~ + a hundred and fifty ° C. The simple requirements for this form of valve are to guarantee a high degree of tightness in the relationship and the tightness of the framework and gasket material.
