Which professional vacuum valve

The valves and pipelines configured in the valve vacuum system should make the pumping time of the system 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 a mechanical pump as the front In the stage pump system, in addition to the foreline pipe (the pipe of the steam flow pump in series with the mechanical pump), there should also be a pre-vacuum pipe (the pipe that connects the vacuum chamber directly to the mechanical pump), followed by the vacuum chamber and main pump There is a high vacuum valve (also called a main valve), and a foreline valve (also called a low vacuum valve) is installed on the foreline pipeline.

High vacuum baffle valve vacuum flange connection or flange joint refers to a foldable connection that is connected by flanges, gaskets and bolts as a set of combined sealing structure. Pipeline flanges refer to piping in pipeline installations. Flange, used on equipment refers to the inlet and outlet flange of the equipment, reliable, can be opened in any direction, easy to disassemble, so easy to clean, vacuum flange uses copper gasket and flange knife edge to achieve vacuum sealing function, vacuum method There are various types of flange covers, fixed and rotatable, and bolt holes are divided into so-called threaded holes and through holes.

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 nominal diameter of the valve vacuum valve: (nominal diameter), also known as the mean outside diameter (meanoutside 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 The 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 known as the nominal diameter and the nominal diameter) is adopted.

The inner diameter, although its value is close to or equal to the inner diameter of the pipe, in order to unify the connecting dimensions of the pipe and fittings, the nominal diameter (also called the nominal diameter and the nominal diameter) is adopted.

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".

Which professional vacuum valve

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

High vacuum flapper valve vacuum valve installation precautions 1. Before installation, the surfaces of the valve in contact with the vacuum should be cleaned according to the vacuum hygiene requirements. 2. The valve should be kept clean and stored in a dry room. 3. The valve should be stored for a long time. Check regularly to prevent moisture, rust and aging of rubber parts. 4. The valve must be installed concentrically with the flanges on both sides. 5. The flange of the user connected to the valve must not have protruding welds in the connecting hole. The orifice needs to be chamfered. If the valve is reassembled after maintenance, it must be subjected to a vacuum performance test.

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.
