Low vacuum valve charge

Maintenance of high vacuum flapper valve body and bonnet The valve body and bonnet are closed shells outside the valve to withstand the pressure of the medium, the additional force during operation, the weight of other parts of the valve, and the flange or thread of the connection The tightness of the valve body and bonnet are required to have certain strength and rigidity. Their damage is mainly local defects caused by medium corrosion, erosion and mechanical damage. When the wall is thinned due to corrosion or erosion, it will even affect them. When the strength and rigidity are high, it cannot be repaired and should be replaced.

When the high vacuum flapper valve opens the valve, when the lifting height of the gate is equal to 1:1 times the valve diameter, the fluid passage is complete, but during operation, this position cannot be monitored. In actual use, the valve stem The apex of the valve is used as a sign, that is, the position where it cannot be opened, as its fully open position. In order to take into account the temperature change, the lock phenomenon occurs. It is usually opened to the apex position, and then back 1/2-1 circle, as the fully open valve The position, therefore, the fully open position of the valve is determined by the position of the gate (that is, the stroke).

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.

What should I pay attention to when installing the vacuum valve? 1. First check whether the solenoid valve is consistent with the selection parameters, such as power supply voltage, medium pressure, pressure difference, etc., especially the power supply. If it is wrong, the coil will be burned out. The power supply voltage should meet the rated voltage and voltage fluctuation range: AC +10%~-15%, DC +10%~-10%, usually the coil components should not be disassembled. 2. The pipeline should be flushed before taking over. The vacuum valve will remove the metal powder and sealing material residues in the pipeline, rust and dirt Wait to be cleared.

High vacuum flapper valve Manual valve is a kind of valve that is widely used in equipment and equipment. It is operated by handle and hand wheel. In general, the clockwise rotation of handle and hand wheel is the closed direction and counterclockwise rotation. The rule is the opening direction, but the opening and closing direction of some valves is opposite to the above. You should pay attention to check the opening and closing signs before operating. For manual valves, the size of the handle and handwheel are planned by normal people. Therefore, in the valve The rule of application: the operator is not allowed to open and close the valve by lever and long wrench.

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.

Vacuum valves learn about cold and anti-freezing content. In autumn, various vacuum valves must be inspected. Vacuum valves are inspected for cold and anti-freezing work of pipelines. Anti-freezing also needs to be divided into regions. The difference between north and south is not small. According to the characteristics of winter, According to the actual situation of the unit, formulate anti-freezing measures for boilers, pressure vessels, pressure pipes and their auxiliary valves and relief devices in winter, and implement the measures in place; increase daily inspections for parts that are prone to freeze and crack, and use vacuum valves for heat preservation The material strengthens the insulation of the device.

High vacuum flapper valve Vacuum valve refers to the vacuum system component used to change the direction of air flow, adjust the size of the air flow, and cut off or connect the pipeline in the vacuum system. The closing part of the vacuum valve is made of rubber sealing ring or metal sealing ring. Sealed, then we will introduce the solid solution and aging treatment of the vacuum valve. The solid solution treatment of the vacuum valve: refers to heating the alloy to a high-temperature single-phase zone to maintain a constant temperature, so that the excess phase is fully dissolved in the solid solution and then quickly cooled to obtain Heat treatment process of supersaturated solid solution.
