High vacuum valve model parameters

The parts of the vacuum valve of the high vacuum 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 subjected to degreasing treatment; after degreasing is completed, pickling passivation is performed. The cleaning agent does not contain phosphorus; after the vacuum valve is pickled and passivated, it is rinsed with pure water, and there should be no residues. This step is omitted for carbon steel parts; each part should be wiped dry with non-woven cloth, and the vacuum valve should not be lined. Wait for the surface of the remaining parts, or blow dry with clean nitrogen.

The design of the high vacuum flapper valve vacuum system should ensure stable and reliable exhaust, easy installation, disassembly and maintenance, convenient operation, and interchangeability of connections between components. In order to achieve stable exhaust during work, stable performance of the main pump is required, and each valve Flexible operation and reliable sealing. The joints of the components in the system do not leak air. The vacuum chamber has good sealing performance. The vacuum components are connected in standard sizes to ensure interchangeability. In the vacuum system design, in principle, each closed tube The road size should have an adjustable size.

Beipiao Vacuum Equipment Co., Ltd. specializes in the research and development, design and production of vacuum valves, vacuum chambers, molecular pumps and molecular pump units with a highly skilled team, and continues to develop new products. Products are widely used in aerospace, technology, coating, solar energy, vacuum furnace industry, energy, metallurgy, chemical industry and many other industries.

There are many types of vacuum valves. They are usually classified according to the valve's function, structure, driving mode, material and purpose. The amount of inflation is measured. There is a small hole of a certain volume in the plunger of the glass valve. When the hole turns to the right and high pressure When the gas cylinder is connected, the small hole can be filled with high-pressure gas; when it is turned to the left and connected to the vacuum container, the volume of high-pressure gas is put into the container, which plays the role of quantitative inflation, through the release valve 5The vacuum degree in the container can be adjusted.

The aging treatment of high vacuum valves and vacuum valves: it can be divided into two types: natural aging and artificial aging. Natural aging is to place the castings in the open field for more than half a year, and then they will gradually form shape, thereby eliminating or reducing residual stress. Artificial aging is The casting is heated to 550～650℃ for stress relief annealing, which saves time than natural aging and removes residual stress. After some alloys are quenched to form a supersaturated solid solution, the vacuum valve is placed at room temperature or a slightly higher appropriate temperature Keep it for a long time to improve the hardness, strength or electrical magnetic properties of the alloy.

The main service groups of Beipiao Vacuum Equipment Co., Ltd.: colleges and universities; research institutes; customers with high vacuum and ultra-high vacuum requirements. The company takes scientific development, forge ahead, the pursuit of excellence, and casting fine products as the development concept. "Customer first, service first" is the business policy.

The vacuum chamber of the vacuum valve vacuum coating machine----According to the difference in the requirements of the processed products, the size of the vacuum chamber is also different. At present, the diameters of 0,9M, 1,3M, 1,5M, 1,8M are more widely used. Etc., the cavity is made of stainless steel, which is not rusty and solid. Each part of the vacuum cavity is equipped with link valves to link the pumps. The auxiliary pumping system of the vacuum coating machine: the exhaust system is coated The important part of the vacuum system consists of three parts: mechanical pump, booster pump/Roots pump, and diffusion pump.

Installation and application of vacuum valve 1. The vacuum valve should be equipped with a filter to prevent impurities in the medium from entering the pressure reducing valve and affecting its performance. 2. Before installing the vacuum valve, it is necessary to flush the piping system to the ground. Dirt such as welding slag, oxide scale, etc. flows into the valve and affects the normal operation of the valve. 3. There should be a straight pipe before and after the pressure reducing valve of the device. The length of the straight pipe before the valve is about 600 mm, and the length of the straight pipe behind the valve is about 1000. Mm, the vacuum valve should be installed in a place convenient for operation and repair.

The main products of Beipiao Vacuum Equipment Co., Ltd. vacuum valves include: ultra-high vacuum flapper valve, high vacuum butterfly valve, high vacuum baffle valve, ultra-high vacuum all-metal angle valve, ultra-high vacuum all-metal fine-tuning valve, etc. The valve diameter ranges from 10mm to 1200mm, the applicable temperature range is -80℃~~+400℃, and the applicable pressure range is 105~~10-8pa.

The main products of the vacuum chamber are: arc structure, round structure, square structure, various vacuum pipes can be processed and manufactured according to the drawings, and the cavity size ranges from 0.1 to 16m.
