High vacuum baffle valve project

High vacuum baffle valve gate valve should not be inverted, otherwise, the medium will stay in the valve cavity for a long time, which will easily corrode the valve stem. Rising stem gate valve should not be installed underneath to prevent the wheel rod from rusting. When installing or replacing heavier gates , Lifting locks cannot be tied to the handwheel or valve stem, but should be tied to the valve body to avoid damage to the handwheel or valve stem and other parts. The check valve has two types: lift check valve and swing check valve. It can only be installed horizontally. The swing check valve must be installed horizontally with its shaft pin. The swing check valve can be used on horizontal and vertical pipelines.

High-vacuum flapper valve The vacuum valve uses an electromagnetic reversing valve to change the direction of the gas path and control the cylinder to drive the ball valve to connect or cut off the medium flow in the vacuum (pressure) system pipeline. It is used in vacuum, dairy products, and wine industries. , Bioengineering, food, pharmacy, beverage, cosmetics and chemical industry, the valve body adopts the traditional appearance design, the valve rigidity is good, the design is reasonable, the passage is smooth, the flow resistance coefficient is small, the packing is flexible PTFE, the sealing is reliable, the operation is light and flexible, The sealing surface is made of stainless steel and hard alloy, with long service life.

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 valve media may contain water in pressure vessels, and the water should be discharged regularly. At the same time, the water discharge valve should be kept warm; at the same time, the drain valve and pipeline should be kept warm; the inverted shower pipeline of the chemical system needs heat preservation; the valves on the boiler, pressure vessel, and pressure pipeline Insulation is required to avoid being frozen and causing malfunction; when doing hydraulic test, the vacuum valve should be kept warm, especially the anti-freezing problem of thin pipes; when the ambient temperature is low, the pressure vessel is easy to freeze. Install the steam accompanying pipe, pay attention to the unblocked steam.

Before the valve safety valve leaves the factory, its opening pressure should be adjusted to the set value required by the user one by one. If the user proposes the spring working pressure level, it should generally be adjusted according to the lower limit of the pressure level. Before the protection device is installed or before installation, it must be re-adjusted at the installation site to ensure that the set pressure value of the safety valve meets the requirements. In order to ensure the accuracy of the pressure value in the opening of the vacuum valve, the media conditions during adjustment, such as the type of medium, The temperature etc. are as close as possible to the actual operating conditions.

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".

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.

The parts of the vacuum valve of the high vacuum flapper 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 degreased; after the degreasing is completed, pickled The cleaning agent does not contain phosphorus; the vacuum valve is washed with pure water after pickling and passivation, and there should be no chemical residue. This step is omitted for carbon steel parts; each part is dried with non-woven cloth, and the vacuum valve cannot Keep wire wool and other parts on the surface, or dry it with clean nitrogen.

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.
