High vacuum baffle valve unit price

Valve vacuum valve, determine the way to operate 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 and work Pressure, working temperature, etc., according to the pipeline conveying medium, working pressure, working temperature to determine the material of the selected valve housing and internal parts: gray cast iron, malleable cast iron, ductile cast iron, carbon steel, alloy steel, stainless acid-resistant steel , Copper alloy, etc.

Vacuum chamber of high-vacuum valve vacuum coating machine----According to the difference in the requirements of processed products, the size of the vacuum chamber is also different. At present, the diameters of 0,9M, 1,3M, 1,5M, 1, 8M, etc., the cavity is made of stainless steel, which is not rusty and solid. Each part of the vacuum cavity has a link valve to link each pump, the auxiliary pumping system of the vacuum valve vacuum coating machine: the exhaust system is An important part of the coating vacuum system, consisting of three parts: mechanical pump, booster pump/Roots pump, and diffusion pump.

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.

High vacuum flapper valve vacuum valve pressure test principles and precautions (1) Generally, the valve is not subjected to strength test, but after repairing the valve body and bonnet or the valve body and bonnet damaged by corrosion, the strength test should be conducted. , Its constant pressure and return pressure and other tests should be in accordance with its instructions and related regulations. (2) The strength and tightness test of the valve installation should be carried out, the low-pressure valve should be spot-checked 20%, and the vacuum valve should be checked if it is unqualified ; Middle and high pressure valves should be checked.

Vacuum valve vacuum valve maintenance method 1. It is recommended to assign a special person in charge for operation and maintenance. 2. Before maintenance, cut off the power supply and remove the medium pressure. 3. The coil assembly should not be disassembled. 4. The vacuum valve steam valve will stop for a long time. When it is put into operation after use, the condensed water should be drained and the operation should be tried several times, and it can be used after normal operation. When the solenoid valve is installed or put into operation after a long period of inactivity, the medium must be introduced and the operation should be tried several times. use.

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.

After the test of the high vacuum flapper valve, 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. During the process of tightening the outer nut, if the joint and the outer nut rotate together, it will be damaged On the sealing surface of the valve body of the product, foreign matter of the vacuum valve is embedded between the diaphragm and the valve seat, compressing or abrading the diaphragm; prevention and elimination method: do not force to close during operation, and open and close repeatedly up and down several times. After the foreign matter is washed away, the valve is officially closed. ; Replace in time when the diaphragm is damaged.

The high vacuum flapper valve can open this valve immediately when the mechanical pump stops working, so that the inlet of the mechanical pump is vented to the atmosphere to prevent the mechanical pump oil from flowing back into the pipeline. Therefore, the valve must be electrically interlocked with the mechanical pump, and the vacuum chamber A deflation valve should also be installed on the upper side for loading and unloading. The position of the valve should take into account that the gas impulse is greater when deflating, so as to prevent the weak components in the vacuum chamber from being damaged due to excessive impulse. The size of is related to the volume of the vacuum chamber, and the deflation time should not be too long, which will affect the work.
