High vacuum flapper valve is of good quality

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 valve Vacuum valve, determine the method of operating the valve: manual, electric, electromagnetic, pneumatic or hydraulic, electric linkage or electro-hydraulic linkage, etc., clarify the purpose of the vacuum valve in the equipment or device, and determine the working conditions of the valve: applicable medium , Working pressure, working temperature, etc., according to the pipeline conveying medium, working pressure, working temperature to determine the material of the selected valve shell and internal parts: gray cast iron, malleable cast iron, ductile cast iron, carbon steel, alloy steel, stainless steel Acid-resistant steel, copper alloy, etc.

Beipiao Vacuum Equipment Co., Ltd. has a technical team with rich practical experience and specializing in the research and development of vacuum equipment. Over the years, through the continuous exploration and innovation of several generations of Beipiao people, the company can design and manufacture high vacuum oil diffusion pumps. , Oil diffusion jet vacuum pumps, various series of vacuum valves and vacuum units, etc., including more than 20 series of vacuum application equipment, more than 100 varieties of products.

ValveVacuum 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, biological engineering, In the fields of food, pharmacy, beverage, cosmetics and chemical industry, the valve body adopts 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 stainless steel sealing surface And cemented carbide, long service life.

High vacuum valve The vacuum valve is driven by electromagnetic force to directly drive the valve plate to open or close the valve. It is suitable for cutting off or conducting air flow in vacuum system. The applicable medium is pure air and non-corrosive gas. With feedback signal. The vacuum butterfly valve changes the direction of the gas path through the electromagnetic reversing valve, and controls the cylinder to drive the butterfly valve to open and close. Used to connect or cut off the air flow in the vacuum pipeline. The applicable medium is pure air and non-corrosive gas. Optional feedback signal device and electric valve.

Since its transformation in 2000, Beipiao Vacuum Equipment Co., Ltd. has injected new vitality and vitality into the enterprise. It has successively developed large-caliber and special-shaped electric and pneumatic high-vacuum flapper valves. It has also developed rapid development for national defense and scientific research departments. Closed high-temperature water-cooled large flapper valve has become a domestic manufacturer of oversized valves.

High vacuum flapper valve is of good quality

The rotation of the high-vacuum flapper valve vacuum valve ball core intercepts the fluid or flows through the ball core, and the force generated by the pressure difference between the upstream and downstream makes the ball core close to the downstream valve seat (floating ball valve structure), in this case The torque of operating the valve is determined by the friction between the ball core and the valve seat, the valve stem and the packing. The flow rate of the vacuum valve flushing and the system should not be less than 3 meters per second. It should be colored by the water color of the outlet. Visual consistency, transparency and transparency of the entrance are limited, and the vacuum valve closing part is sealed with a rubber sealing ring or a metal sealing ring.

High vacuum baffle valve vacuum valve often neglects the pressure problem during grease injection. During the grease injection operation, the grease injection pressure changes regularly, the pressure is too low, the seal leaks or the failure pressure is too high, and the grease injection port is blocked. If the grease is hardened or the sealing ring is locked with the valve ball and valve plate, and the grease injection pressure is too high, check the grease nozzle on the one hand, if the grease hole is blocked, replace it; on the other hand, the fat is hardened. Clean fluid, seal grease that has repeatedly failed, and inject new grease to replace it.
