Which high vacuum flapper valve is better

If the high vacuum baffle valve is classified according to the working pressure of the actual starting system, it can be divided into rough vacuum system, low vacuum system, high vacuum system, ultra-high vacuum system and extremely high vacuum system. If it is divided according to the cleanness of the vacuum system, it will There are oil vacuum systems and oil-free vacuum systems. Due to people’s habits, the above-mentioned different classifications are often integrated in practical applications, such as "large dynamic metal high vacuum systems", "oil-free ultra-high vacuum systems", etc. , The above classification method is not strictly unchanged.

High vacuum flapper 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 pipeline systems. In line with GMP standards, the electric vacuum valve adopts an electric actuator to drive the valve stem to turn 90o to achieve the purpose of switching. M3/S changes the status quo that the ball valve cannot meet high vacuum and ultra-high vacuum; the switching torque is small, the electric actuator is small, and the work is stable. ,reliable.

Beipiao Vacuum Equipment Co., Ltd. specializes in the research and development, design and production of vacuum valves, vacuum chambers, molecular pumps and molecular pump units with a highly skilled team, and continues to develop new products. Products are widely used in aerospace, technology, coating, solar energy, vacuum furnace industry, energy, metallurgy, chemical industry and many other industries.

High-vacuum flapper valve solenoid vacuum with charging valve and solenoid vacuum differential pressure valve are vacuum valves specially used to prevent oil from returning to mechanical vacuum pumps. They are installed at the inlet of mechanical vacuum pumps and open and close synchronously with the pump. Generally, they cannot be used. In other places, that is to say, it cannot be used for venting in the vacuum system. The advantage of using the Nivel electromagnetic vacuum differential pressure valve is that it consumes very little power and saves energy; the valve body with DN≤50 is made of aluminum alloy and weight Light weight, small size, fast closing speed of the valve plate.

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 main service groups of Beipiao Vacuum Equipment Co., Ltd.: colleges and universities; research institutes; customers with high vacuum and ultra-high vacuum requirements. The company takes scientific development, forge ahead, the pursuit of excellence, and casting fine products as the development concept. "Customer first, service first" is the business policy.

Which high vacuum flapper valve is better

When the vacuum valve of the high vacuum flapper valve leaks, the leak location and cause should be identified first. Under normal circumstances, there are two types of leakage and external leakage. External leakage is divided into leakage at the packing and leakage at the valve cover and valve body according to its external structure. As well as the leakage of sealing surface or fabric materials, the operator should judge that if he can solve it, he should deal with it in time, and if it can’t be solved, the maintenance worker should deal with it in time. The vacuum valve packing gland should not be pressed too tightly, and the valve stem should be able to rotate sensitively. , Pressing too tightly will increase the friction of the valve stem and increase the operating torque.

High vacuum flapper valve. When the temperature of the medium in the vacuum valve body cavity rises to cause abnormal pressure rise, it does not need to pass through the safety valve, but the valve seat function can automatically release the pressure, which ensures the safety of the valve when transporting liquid media. It is very important. Among the basic conditions of vacuum valves, the essential positioning goals of the valve are consistent with the needs of life. It is also a reliable choice that allows the practical valve function to achieve better application possibilities, especially the production of brand-style valves. Selection is the key to valve function positioning and quality assurance.
