High vacuum baffle valve manufacturer

When the high vacuum flapper valve vacuum valve is used for leak detection on the welding seam of the cold trap inner tank after assembly, the welding seam cannot be exposed to the outside after assembly, even if a leak is found, it cannot be repaired, as in some large containers. After the final assembly, the volume is too large, so that the leak detection sensitivity is very low, and the vacuum valve cannot detect small leaks, thus failing to meet the requirements of leak detection. Considering similar situations, it should be used in the processing of parts and components. During the process, leak detection was performed on the weld, and the solution of broken bolts in the vacuum valve.

Vacuum valve Vacuum valve refers to the vacuum system components used in the vacuum system to change the direction of air flow, adjust the size of the air flow, and cut off or connect the pipeline. When the vacuum valve leaks, the location and cause of the leak should be identified first. There are two types of leakage and external leakage. According to the external structure, external leakage can be divided into packing leakage, valve cover, valve body leakage, and sealing surface or fabric data leakage. The operator should judge and deal with it in time if it can solve it. Maintenance workers should deal with the problems that cannot be solved in time.

Beipiao Vacuum Equipment Co., Ltd. (formerly Beipiao Vacuum Valve Factory) was established in 1966 and is a designated enterprise of the former Ministry of Machinery and Electronics. The total area of the plant is over 50 acres. The main plant is located in the Taiji Management Zone of Beipiao City. The new plant is located in the Light Textile Industrial Park of the Economic Development Zone of Beipiao City. The total investment exceeds 100 million yuan. There are 62 employees, including 12 engineers and technicians. The company has more than 100 sets of various processing and manufacturing equipment and nearly 20 patented technologies. Over the years, it has been innovating and making progress. It has grown into a professional vacuum acquisition, A high-tech enterprise engaged in vacuum application technology development and equipment manufacturing.

The valves and pipes configured in the high vacuum flapper valve vacuum system should make the system pumping time short, easy to use, safe and reliable. Generally, there is a vapor flow pump as the main pump (diffusion pump or oil booster pump); and In the system where the mechanical pump is used as the backing pump, in addition to the backing pipeline (the pipeline of the vapor flow pump in series with the mechanical pump), there should also be a pre-vacuum pipeline (the vacuum chamber is directly connected to the mechanical pump), followed by the vacuum chamber and A high vacuum valve (also called a main valve) is arranged between the main pumps, and a foreline valve (also called a low vacuum valve) is arranged on the foreline pipeline.

Principles and precautions for pressure test of high vacuum flapper valve (1) Generally, the valve is not subjected to strength test, but after repair, the valve body and bonnet or the valve body and bonnet damaged by corrosion should be subjected to strength test. , 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.

The company is located in Beipiao City, Liaoning Province, in the west of Liaoning Province, with the Bohai Sea in the south and Inner Mongolia in the north. It is an important part of the Bohai Rim Economic Circle. Beipiao City is rich in fossil resources and mineral resources. 44 types of mineral resources have been proven. Among them, gold mineral reserves are very rich, and the fossil industry is prosperous and diverse. It is known as "the world's first bird flying and the first flower blooming." The reputation of "place".

High vacuum flapper valve The vacuum valve is driven by electromagnetic force to directly drive the valve plate to open or close the valve. It is suitable for cutting off or conducting air flow in vacuum system. The applicable medium is pure air and non-corrosive gas. With feedback signal. The vacuum butterfly valve changes the direction of the gas path through the electromagnetic reversing valve, and controls the cylinder to drive the butterfly valve to open and close. Used to connect or cut off the air flow in the vacuum pipeline. The applicable medium is pure air and non-corrosive gas. Optional feedback signal device and electric valve.

The inner wall of the valve body is susceptible to medium impact and corrosion when used in high pressure difference and corrosive media. Check the pressure and corrosion resistance, valve seat, check the wear condition of the valve seat and fix the valve seat Whether the inner and outer surface of the thread used is corroded and the valve seat is loosened, the main points of the inspection and repair 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 wear of the valve core The cavitation caused by cavitation is more severe.

The transportation in Beipiao City is very convenient. The Beijing-Shenzhen high-speed railway can directly connect to Beijing, Shenyang and other cities. National highways 101 and 305 and Changshen Expressway run through urban and rural areas. The central city is 45 kilometers away from Chaoyang Airport and 150 kilometers away from Jinzhou Port.
