High vacuum baffle valve model

High-vacuum valve When the vacuum valve leaks, attention should be paid to the location and cause of the leakage. There are two common types: duty leakage and external leakage. External leakage can be divided into packing leakage and valve cover, valve body leakage and sealing according to its external structure. If there is leakage of surface or fabric data, the operator should judge that if he can solve it, he should deal with it in time, and the maintenance worker should deal with it in time. The electromagnetic vacuum belt inflation valve and electromagnetic vacuum pressure difference valve are specially used to prevent the mechanical vacuum pump from returning oil. The vacuum valve is installed at the air inlet of the mechanical vacuum pump and opens and closes synchronously with the pump.

What should I pay attention to when installing 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.

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 parts of the vacuum valve of the high vacuum flapper valve are processed before assembly. According to the processing requirements, some parts need to be polished, and the surface must not have processing burrs, etc.; all parts are degreased; after the degreasing is completed, pickled The cleaning agent does not contain phosphorus; the vacuum valve is washed with pure water after pickling and passivation, and there should be no chemical residue. This step is omitted for carbon steel parts; each part is dried with non-woven cloth, and the vacuum valve cannot Keep wire wool and other parts on the surface, or dry it with clean nitrogen.

The accuracy of the function of the vacuum valve is high, and the realization of effective adjustment of the airflow direction and size of the vacuum environment is the standard that its function needs to meet. As a ball valve product used under vacuum conditions, the vacuum ball valve is not only cut-off The basic function positioning has standard accuracy, and while realizing the effective cut-off function guarantee, it can also serve the needs of vacuum environment management. It is necessary to ensure that there are good management functions. The vacuum valve products Practice application.

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 valve Nominal diameter of vacuum valve: (nominal diameter), also known as mean outer diameter (mean outside diameter), represents the symbol DN, which is the general diameter of various pipes and pipeline accessories. It is not the actual pipe outer diameter or inner diameter. Although its value is close to or equal to the inner diameter of the pipe, in order to make the connection size of the pipe and fittings uniform, the nominal diameter (also called the nominal diameter and the nominal diameter) is adopted.

The trapezoidal thread of the valve stem and stem nut of the high vacuum baffle valve 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 overhauled and installed, the sealing function test should be carried out, and the vacuum valve should be carefully disassembled and assembled. Valve packaging, 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, check the valve to indicate the sign of the flow direction.
