Complete specifications of high vacuum baffle valve

High vacuum baffle valve vacuum valve nominal diameter: (nominaldiameter), also known as mean outside diameter (meanoutsidediameter), represents the symbol DN, which is the general diameter of various pipes and pipeline accessories. 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 internal and external surfaces of the carbon steel valve of the vacuum valve are treated with anti-corrosion treatment. The driving methods are manual, electric, pneumatic, and gear transmission. They are widely used in oil and steam pipeline networks such as petrochemicals and thermal power plants. Vacuum valves are used in vacuum systems. It is used to change the direction of air flow, adjust the size of the air flow, and cut off or connect the pipeline components of the vacuum system. The closing part of the vacuum valve is sealed with a rubber sealing ring or a metal sealing ring. The basic requirement of the vacuum valve is to ensure the connection High tightness and compactness of the structure and gasket material.

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.

Maintenance of high vacuum flapper valve body and bonnet. The valve body and bonnet are closed shells outside the valve to withstand the pressure of the medium, the additional force during operation, the weight of other parts of the valve, and the flange or thread of the connection The tightness of the valve body and bonnet are required to have certain strength and rigidity. Their damage is mainly local defects caused by medium corrosion, erosion and mechanical damage. When the wall is thinned due to corrosion or erosion, it will even affect them. When the strength and rigidity are high, it cannot be repaired and should be replaced.

The vacuum field of high vacuum valves has always been an unreachable field before. It was at this time in the 21st century that the application of the vacuum field was gradually familiarized by people. The meaning of vacuum means that it is lower than in a given space. A gas state under atmospheric pressure is a physical phenomenon. In the "void", sound cannot be transmitted because there is no medium, but the transmission of electromagnetic waves is not affected by vacuum. In fact, in vacuum technology, vacuum is aimed at the atmosphere. In other words, part of the substance in a specific space is discharged.

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".

Daily maintenance methods of vacuum valves: 1. Valves stored for a long time should be checked regularly, cleaned of dirt, and anti-rust oil should be applied to the processing surface. 2. The valves should be stored in a dry and ventilated room. The two ends of the passage must be blocked and vacuum Valve 3, after installation, should be checked regularly. The first things to check are: the wear condition of the sealing surface, the wear condition of the trapezoidal thread of the valve stem and the valve stem nut, whether the packing is out of date and invalid, if it is damaged, it should be replaced in time. After the valve is repaired and installed, it should be Carry out sealing function experiment.

The vacuum part of the valve 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 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 are commonly used conical surfaces and Spherical contact.

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.
