High vacuum flapper valve vacuum valve nominal pressure: (Nominalpressure), which means the symbol PN, the allowable working pressure when applied at a certain temperature, for carbon steel valve body control valves, it refers to the allowable working pressure when applied below 200℃; Cast iron valve body refers to the allowable working pressure for applications below 120°C; for control valves with stainless steel body, it refers to the allowable working pressure for applications below 250°C. When the working temperature rises, the pressure resistance of the valve body will decrease.

High vacuum baffle valve, vacuum valve storage and maintenance method The purpose of storage and maintenance is to prevent damage to the valve during storage, or reduce the quality. In fact, improper storage is one of the important reasons for valve damage. Vacuum valve valve storage should be organized. The small valves are placed on the shelf, and the large valves can be neatly arranged on the floor of the warehouse. They should not be piled up in disorder. Do not let the flange connection surface contact the ground. This is not only for aesthetics, but also to protect the valves from damage due to improper storage and handling. The handwheel is broken and the valve stem is crooked.

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.

The trapezoidal thread of the valve stem and stem nut is worn, and the packing is out of date and invalid. If it is damaged, it should be replaced in time. After the valve is repaired and installed, the sealing function test should be carried out. When installing the vacuum valve, the valve packaging should be carefully disassembled , Check the labels or signs against the list of materials, specifications and schedules to ensure that they meet the requirements of the order and working conditions. Pay attention to the special warning labels or signs attached to the valve or accompanying the valve, and take appropriate measures to check the valve A sign indicating the direction of flow.

High vacuum valve Vacuum valve refers to the vacuum system components used to change the direction of air flow, adjust the size of air flow, and cut off or connect the pipeline in the vacuum system. The closing part of the vacuum valve is sealed with a rubber sealing ring or a metal sealing ring. , Vacuum valve is a widely used valve on equipment and equipment. It is operated by handles and handwheels. Generally, the clockwise rotation of the handle and handwheel is the closed direction, and the counterclockwise rotation is the open direction. , But some valve opening and closing directions are opposite to the above.

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 vacuum part of the high-vacuum flapper valve vacuum valve is mainly composed of the interlayer between the inner valve body and the outer valve body. The more gas in the interlayer, the more intense the convective heat transfer. In order to reduce the influence of convective heat transfer, the interlayer should be pumped. In vacuum treatment, the heat transfer of residual gas belongs to the migration of gas. For the gas heat conduction of the vacuum interlayer, the gas conduction mechanism of the vacuum valve is different with the strength of the interlayer. The sealing structure of the inlet and outlet of the vacuum valve and the pressure test joint is commonly used. The conical surface is in contact with the spherical surface.

Installation and application of the vacuum valve 1. The vacuum valve should be equipped with a filter to prevent impurities in the medium from entering the pressure reducing valve and affecting its performance. 2. Before installing the vacuum valve, it is necessary to flush the pipeline system to the ground to prevent Dirt such as welding slag and oxide scale flows into the valve, affecting the normal operation of the valve. 3. There should be a straight pipe before and after the pressure reducing valve of the device. The length of the straight pipe before the valve is about 600 mm, and the length of the straight pipe behind the valve is about 1000 mm. , The vacuum valve should be installed in a place that is convenient for operation and repair.
