Which valve to choose

The sealing performance of a valve refers to the ability of each sealing part of the valve to prevent medium leakage. It is an important technical performance index of the valve. There are three sealing parts of the valve: the contact between the opening and closing parts and the two sealing surfaces of the valve seat; the packing and the valve The matching point of the rod and the stuffing box; the connection between the valve body and the bonnet, where the previous leakage is called internal leakage, which is commonly referred to as loose closing, which will affect the ability of the valve to cut off the medium. For the shutoff valve For classes, internal leakage is not allowed.

The professional maintenance of high vacuum valves before and after they are put into production is very important for the valve to serve in production and operation. Correct, orderly and useful maintenance will maintain the valve and make the valve function normally. Extend the service life of the valve. The maintenance of the valve seems simple, but it is not. There are often overlooked aspects in the operation. When the vacuum valve is greased, the problem of grease injection is often ignored. After grease injection, the operator chooses the valve and grease injection joint After the method, perform grease injection.

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.

Vacuum valves For vacuum valves operating at high temperatures, when the temperature rises above 200 ℃, the bolts will be stretched by heat, which will easily cause the valve to be tightly sealed. When necessary, the bolts should be "hot tightened". When the low temperature is below 0℃, the vacuum valve must be protected against freezing first, and the valve bottom wire plug should be opened in time to drain the condensed water inside, so that it cannot be swept away. Valves with high and continuous operation should be kept warm.

The vacuum valve vacuum system is widely used in various processes. There are many types. According to the state of the vacuum system pumping process, it can be divided into two basic types, open vacuum system and closed vacuum system, the so-called open vacuum The system, like the gas flow in the system, the pressure varies from place to place, there will be a pressure difference between each section of the vacuum system, the first-stage vacuum pump will be pumped to the atmosphere, and the closed vacuum system is the pumping equipment It is enclosed with the pumped container.

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".

Which valve to choose

High vacuum valve vacuum valve often neglects the pressure problem during grease injection. During the grease injection operation, the grease injection pressure changes regularly, the pressure is too low, the seal leaks or the failure pressure is too high, the grease injection port is blocked, and the seal is inside. If the fat is hardened or the sealing ring is locked with the valve ball and valve plate, and the grease injection pressure is too high, on the one hand, check the grease injection nozzle, if the grease hole is blocked, replace it; on the other hand, if the fat is hardened, use cleaning fluid , Repeated failure of the sealing grease, and inject new grease replacement.

High vacuum flapper valve The vacuum valve is driven by electromagnetic force to directly drive the valve plate to open or close the valve. It is suitable for cutting off or conducting air flow in vacuum system. The applicable medium is pure air and non-corrosive gas. With feedback signal. The vacuum butterfly valve changes the direction of the gas path through the electromagnetic reversing valve, and controls the cylinder to drive the butterfly valve to open and close. Used to connect or cut off the air flow in the vacuum pipeline. The applicable medium is pure air and non-corrosive gas. Optional feedback signal device and electric valve.

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.
