How much is the high vacuum valve

The valves and pipes configured in the high vacuum flapper 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 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.

High-vacuum flapper valves, gate valves and globe valves, etc., when closed or opened to the end (ie bottom dead center or top dead center), they must be reversed 1/4 to 1/2 turn to make the threads more tightly closed. Check when it is advantageous to operate to prevent over-tightening and damaging the valve. Large-diameter butterfly valves, gate valves and stop valves, and some are equipped with bypass valves. The function of the bypass valve is to balance the pressure difference between the inlet and outlet and reduce the opening torque. , The bypass valve should be turned on first, and then the large valve should be opened. Before opening the steam valve, it is necessary to preheat the pipeline to discharge the condensate.

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 medium type of the high vacuum flapper valve changes, especially when the medium accumulation state is different (for example, from the liquid phase to the gas phase), the opening pressure often changes. When the working temperature rises, the opening pressure generally decreases, so at room temperature When used for high temperature adjustment, the set pressure value at room temperature should be slightly higher than the required opening pressure value. How high it is depends on the valve structure and material selection. It should be based on the manufacturer's instructions. Vacuum valve stainless steel The joint material is generally 1Cr18Ni9Ti or 0Cr18Ni9, and its hardness is close to the valve body.

Vacuum valve, if the valve body leaks when the vacuum valve is used in the pipeline, we can take advantage of the fast curing speed of the adhesive to fill the pin with the adhesive in time to establish a new solid sealing structure to achieve the purpose of preventing leakage. It is a method of using the special function of the adhesive to plug leaks under pressure. Different transmission principles have different operating principles. Therefore, customers should pay attention to them when purchasing and choose different transmission principles according to their actual conditions. The vacuum valve.

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".

How much is the high vacuum valve

Vacuum valve Vacuum valve refers to the vacuum state of the inner cavity of the valve, usually called negative pressure, and the inner cavity pressure is lower than atmospheric pressure. The valves used in the vacuum piping system include vacuum ball valves, vacuum butterfly valves, vacuum diaphragm valves, etc. The medium is high purity , Ball valves, gate valves, globe valves, etc. can all be produced into vacuum valves and ordinary conventional valves. There is no difference in appearance of vacuum valves. There are differences in the design of valve connection parts. It is only a matter of detail. For this type of valve The basic requirement is to ensure the high degree of sealing of the connection and the compactness of the structure and gasket material.
