Where is the vacuum valve

The vacuum part of the high-vacuum flapper 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 pumped. In vacuum treatment, the heat transfer of residual gas belongs to the migration of gas. For the gas heat conduction of the vacuum interlayer, the gas conduction mechanism of the vacuum valve is different with the strength of the interlayer. The sealing structure of the inlet and outlet of the vacuum valve and the pressure test joint is commonly used. The conical surface is in contact with the spherical surface.

Vacuum valve Electric vacuum valve is a pneumatic valve used to open or block air flow in a vacuum system of 1,3×10-7～6×105Pa. It is widely used in various types of gas, liquid and other positive and negative pressure piping systems, in line with GMP standards , The electric vacuum valve adopts an electric actuator to drive the valve stem to rotate 90o to achieve the purpose of switching. M3/S changes the status quo that the ball valve cannot meet the high vacuum and ultra-high vacuum; the switching torque is small, the electric actuator is small, and the work is stable and reliable.

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 factory is over 50 acres, the main factory is located in the Taiji Management Zone of Beipiao City, and the new factory is located in the Light Textile Industrial Park of the Economic Development Zone of Beipiao City, with a total investment of over 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 of vacuum application technology development and equipment manufacturing.

High vacuum flapper valve vacuum valve pressure test principles and precautions (1) Generally, the valve is not subjected to strength test, but after repairing the valve body and bonnet or the valve body and bonnet damaged by corrosion, the strength test should be conducted. , Its constant pressure and return pressure and other tests should be in accordance with its instructions and related regulations. (2) The strength and tightness test of the valve installation should be carried out, the low-pressure valve should be spot-checked 20%, and the vacuum valve should be checked if it is unqualified ; Middle and high pressure valves should be checked.

High vacuum flapper valve The vacuum valve changes the direction of the gas path through the electromagnetic reversing valve, and controls 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 design, the valve rigidity is good, the design is reasonable, the passage is smooth, the flow resistance coefficient is small, the packing is made of flexible PTFE, the sealing is reliable, the operation is light and flexible, The sealing surface is made of stainless steel and hard alloy, which has a long service life.

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".

Where is the vacuum valve

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.

Vacuum valve Vacuum valve refers to a vacuum system component used in the vacuum system to change the direction of air flow, adjust the size of the air flow, and cut or connect the pipeline. The closing part of the vacuum valve is sealed with a rubber seal or a metal seal , The gate of the vacuum valve moves linearly with the valve stem. It is called a lifting stem gate valve (also called a rising stem gate valve). There is usually a trapezoidal thread on the lifting stem. The nut on the top of the valve and the guide groove on the valve body Rotational motion becomes linear motion, that is, operating torque is transformed into operating thrust.

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.
