The mechanical principle and classification of the vacuum valve vacuum coating machine: Mechanical pump: also called the backing pump. The mechanical pump is a kind of low vacuum pump that is widely used. It uses oil to maintain the sealing effect and relies on mechanical methods to continuously change the pump. The volume of the inner suction cavity causes the volume of the gas in the pumped container to continuously expand to obtain a vacuum. The classification of mechanical pumps: There are many types of mechanical pumps. Commonly used are slide valve type (mainly used for large equipment), piston reciprocating type, Fixed vane type and rotary vane type (this is currently widely used) vacuum valves.

Precautions for the use of the valve vacuum valve 1. When the vacuum valve is stored and transported, the pressure of the sealing parts will be reduced, which will cause the loosening of the screws and nuts. In order to avoid the leakage caused by this, the vacuum valve must be used before use Tighten each screw. 2. When the vacuum valve uses high-temperature fluids such as steam, the tightened screws will become loose due to the reduced pressure on the sealing parts, resulting in leakage. Therefore, the loose screws should be tightened immediately.

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.

High-vacuum flapper valve solenoid vacuum with charging valve and solenoid vacuum differential pressure valve are vacuum valves specially used to prevent oil from returning to mechanical vacuum pumps. They are installed at the inlet of mechanical vacuum pumps and open and close synchronously with the pump. Generally, they cannot be used. In other places, that is to say, it cannot be used for venting in the vacuum system. The advantage of using the Nivel electromagnetic vacuum differential pressure valve is that it consumes very little power and saves energy; the valve body with DN≤50 is made of aluminum alloy and weight Light weight, small size, fast closing speed of the valve plate.

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

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".

Vacuum valve The vacuum part of the vacuum valve is mainly composed of the interlayer between the inner valve body and the outer valve body. The more gas in the interlayer, the more intense the convective heat transfer. In order to reduce the influence of convective heat transfer, the interlayer 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, the heat conduction mechanism of the vacuum valve gas is different with the strength of the interlayer. The sealing structure of the inlet and outlet ends of the vacuum valve and the pressure test joint is a commonly used conical surface Contact with the spherical surface.

After the vacuum valve is assembled, the welding seam of the vacuum valve cannot be exposed to the outside. my country's vacuum equipment industry has made great development and considerable improvement since its opening for more than 20 years. This is not only reflected in the substantial increase in output value and output, but also in types , Specifications and comprehensive technical levels have achieved considerable achievements. China's vacuum equipment industry has made great development and substantial improvement since its opening for more than 20 years.
