The sealing performance test of the valve vacuum baffle valve. Opening and closing force and opening and closing torque refer to the force or torque that must be applied to open or close the valve. When closing the valve, it is necessary to form a certain gap between the opening and closing parts and the two sealing surfaces of the seat. The specific pressure of the seal must also overcome the friction between the stem and the packing, between the thread of the stem and the nut, the end support of the stem and other frictional parts, so a certain closing force and closing torque must be applied. In the opening and closing process, the required opening and closing force and opening and closing torque are changed, and the maximum value is at the final moment of closing or the initial moment of opening.

High vacuum baffle valve 1, unique sealing structure design, leakage rate can reach <1×10-10Pa, M3/S, changing the current situation that ball valves cannot meet high vacuum and ultra-high vacuum; 2, switching torque is small, equipped with electric execution The device is small, stable and reliable; 3. Compact structure, light weight, simple and beautiful appearance; 4. The valve can be used under both high vacuum and a certain positive pressure; 5. Because the ball valve is fully open and conductive, It can meet the requirements of ultra-high vacuum, so it can also be applied to accelerator vacuum system.

Beipiao Vacuum Equipment Co., Ltd. specializes in the research and development, design and production of vacuum valves, vacuum chambers, molecular pumps and molecular pump units with a highly skilled team, and continues to develop new products. Products are widely used in aerospace, technology, coating, solar energy, vacuum furnace industry, energy, metallurgy, chemical industry and many other industries.

High vacuum valve 1. Unique sealing structure design, leakage rate can reach <1×10-10Pa, M3/S, changing the status quo that ball valves cannot meet high vacuum and ultra-high vacuum; 2. Small switching torque and small electric actuator , The work is stable and reliable; 3. The structure is compact, light in weight, simple and beautiful; 4. The valve can be used under high vacuum and a certain positive pressure; 5. Because the ball valve is fully open, it can reach Ultra-high vacuum requirements, so it can also be applied to accelerator vacuum systems.

When the vacuum valve is leak-tested on the weld of the cold trap liner after the assembly, the weld cannot be exposed to the outside after assembly, even if a leak is found, it cannot be repaired. Another example is that some large vessels are after the assembly. The volume is too large, so that the leak detection sensitivity is very low, and the vacuum valve cannot detect small leaks, thus failing to meet the requirements of leak detection. Considering similar situations, it should be done during the processing of parts and components. Welds are leak-tested, and the vacuum valve has broken bolts.

The main service groups of Beipiao Vacuum Equipment Co., Ltd.: colleges and universities; research institutes; customers with high vacuum and ultra-high vacuum requirements. The company takes scientific development, forge ahead, the pursuit of excellence, and casting fine products as the development concept. "Customer first, service first" is the business policy.

Vacuum valve The vacuum valve changes the direction of the gas path through the electromagnetic reversing valve, and controls the cylinder to drive the ball valve to connect or cut off the medium flow in the vacuum (pressure) system pipeline. It is used in vacuum, dairy products, wine industry, and biological engineering. , Food, pharmacy, beverage, cosmetics and chemical industry, the valve body adopts the traditional exterior design, the valve has good rigidity, reasonable design, smooth passage, small flow resistance coefficient, flexible PTFE packing, reliable sealing, light and flexible operation, and the sealing surface adopts Stainless steel and hard alloy have long service life.

The sealing performance test of the high vacuum flapper valve The opening and closing force and opening and closing torque of the vacuum flap valve refer to the force or torque that must be applied to open or close the valve. When closing the valve, it is necessary to make the two sealing surfaces of the opening and closing member and the seat A certain seal specific pressure is formed between them, and the friction between the valve stem and the packing, between the thread of the valve stem and the nut, the end support of the valve stem and other frictional forces must be overcome, so a certain closing force and Closing torque. During the opening and closing process of the valve, the required opening and closing force and opening and closing torque are changed, and the maximum value is at the final moment of closing or the initial moment of opening.
