Valve contact

High vacuum flapper valve The device orientation of the vacuum valve should be far away from the vibration source. If it is unavoidable, preventive measures should be taken. This kind of vibration of the entire regulating valve, before reaching resonance, the regulating valve can basically be adjusted with the external given signal. Because the relative displacement of the external given signal to the spool is not changed or changed very little due to the vibration of the entire regulating valve, the reason is that they are a whole. The stop valves at both ends of the regulating valve open or close suddenly, and the reflected wave impacts the regulating valve core.

After the high-vacuum valve test, the joint and the sealing part of the valve body are deformed at the same time, and the sealing surface of the valve body will produce indentation, which is not conducive to multiple sealing. If the joint and the outer nut are rotated together during the tightening process, the product will be damaged. On the sealing surface of the valve body, foreign objects of the vacuum valve are embedded between the diaphragm and the valve seat, compressing or wearing the diaphragm; prevention and elimination methods: do not forcibly close during operation, and open and close repeatedly up and down several times. After washing away the foreign objects, formally close the valve; Replace it in time after damage.

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.

For high-vacuum valves with standard gate valves and throttle valves, you should check and adjust the fully open or fully closed indication position. Rising stem gate valves and globe valves should also use their fully open and fully closed positions to prevent them from being fully opened. When the mouth is dead, and when the valve is fully closed, you can use the ruler and marks to find that the closure has fallen or resisted foreign objects to troubleshoot. The pipeline and equipment of the new installation have more internal dirt and welding ballast. Normally open manual Dirt is simply stuck on the valve sealing surface. Use the micro-opening method to let the high-speed medium wash away these foreign objects.

There are many types of high vacuum flapper valves. Vacuum valves are usually classified according to the valve's function, structure, drive mode, material and purpose. When it turns to the right to connect with the high-pressure gas cylinder, the small hole can be filled with high-pressure gas; when it turns to the left to connect to the vacuum container, the volume of high-pressure gas is put into the container, which plays the role of quantitative inflation. The vacuum level in the container can be adjusted through the air release valve 5.

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.

The routine maintenance method of the valve vacuum valve: 1. The valve stored for a long time should be checked regularly, cleaned up the dirt, and coated with anti-rust oil on the processing surface. 2. The valve should be stored in a dry and ventilated room. The two ends of the passage must be blocked. The vacuum valve 3. After installation, check regularly. The first check items: the wear condition of the sealing surface, the wear condition of the trapezoidal thread of the valve stem and the valve stem nut, whether the packing is out of date and invalid, if it is damaged, it should be replaced in time, and the valve should be repaired after installation. Sealing function experiment.

The inner wall of the vacuum valve valve body is vulnerable to medium impact and corrosion when used in high pressure difference and corrosive medium. Check the pressure and corrosion resistance status, valve seat, check the wear condition of the valve seat and the fixed valve The threaded inner and outer surface of the seat, whether the seat is loose due to corrosion, the main points of the maintenance of the pneumatic membrane control valve, check the position, the valve core, the valve core is the movable part of the control valve, and the valve core is worn The phenomenon of cavitation caused by cavitation is more severe.
