What are the vacuum valves

When the vacuum valve is used in the device, the shut-off valve on the bypass pipeline should be opened first to remove the condensate and steam-water mixture in the pipeline to prevent water hammer from damaging the pressure reducing valve when the pressure reducing valve is opened. After the abnormal phenomenon, slowly rotate the screw clockwise to adjust the outlet pressure to the required pressure (according to the gauge pressure after the valve). After adjustment, lock the lock nut, screw on the protective cover, and reducer It should be stored in a dry room. The two ends of the passage must be blocked with blind plates. Stacking storage is prohibited.

High vacuum flapper valve vacuum valve aging treatment: it can be divided into two types: natural aging and artificial aging. Natural aging is to place the castings in the open field for more than half a year, and then they will gradually take shape, thereby eliminating or reducing residual stress. Aging is to heat the casting to 550～650℃ for stress relief annealing. Compared with natural aging, it saves time and removes residual stress. After some alloys are quenched to form a supersaturated solid solution, the vacuum valve is placed at room temperature or higher. Keep the temperature for a long time to improve the hardness, strength or electrical magnetic properties of the alloy.

Beipiao Vacuum Equipment Co., Ltd. has a technical team with rich practical experience and specializing in the research and development of vacuum equipment. Over the years, through the continuous exploration and innovation of several generations of Beipiao people, the company can design and manufacture high vacuum oil diffusion pumps. , Oil diffusion jet vacuum pumps, various series of vacuum valves and vacuum units, etc., including more than 20 series of vacuum application equipment, more than 100 varieties of products.

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.

High-vacuum flapper valve The vacuum valve uses an electric device to drive the valve stem and ball core to perform opening and closing actions to connect or cut off the medium flow in the vacuum (pressure) system pipeline. It is used in vacuum, dairy, wine, and In the fields of bioengineering, food, pharmacy, beverage, cosmetics and chemical industry, in order to ensure the elasticity of the packing when the vacuum valve leaves the factory, it is generally subject to the static pressure test. After the valve is installed in the pipeline, due to temperature and other factors, Extravasation may occur, and the nuts on both sides of the packing gland must be tightened in time.

Since its transformation in 2000, Beipiao Vacuum Equipment Co., Ltd. has injected new vitality and vitality into the enterprise. It has successively developed large-caliber and special-shaped electric and pneumatic high-vacuum flapper valves. It has also developed rapid development for national defense and scientific research departments. Closed high-temperature water-cooled large flapper valve has become a domestic manufacturer of oversized valves.

What are the vacuum valves

High-vacuum flapper valve Vacuum valve refers to the vacuum system component used to change the direction of air flow, adjust the size of air flow, and cut off or connect the pipeline in the vacuum system. The closing part of the vacuum valve is made of rubber sealing ring or metal sealing ring. Sealed, vacuum valve packing gland should not be over-tightened. It is advisable that the valve stem can rotate sensitively. Pressing too tightly will increase the frictional force of the valve stem and increase the operating torque. Generally speaking, it cannot be Replace or add packing under pressure at will, otherwise, the medium will leak and cause risks.
