Pneumatic valve base is introduced

Pneumatic valve is a valve he possesses the advantages of simple structure to save material. The following specific introduction of it. Pneumatic valve is composed of pneumatic actuators and valve. Pneumatic valve is made with the valve rod rotation round plate, to be opened in order to realize the opening action of pneumatic valves, mainly for block valves use, can also be designed to have a adjustment or section of the valve and the adjustment function, the valve in the low voltage and medium caliber pipeline on the use of more and more. Pneumatic valve categories: stainless steel pneumatic valve, pneumatic valve, hard seal, soft seal pneumatic valve, pneumatic valve is carbon steel. The major advantages of the pneumatic valve, simple structure, small volume light weight, low cost, the characteristics of the pneumatic valve is particularly significant, installed in the upper air tunnel, through two five-way solenoid valve control is easy to operate, also can adjust flow medium. The major advantages of the pneumatic valve, simple structure, small volume light weight, low cost, the characteristics of the pneumatic valve is particularly significant, installed in the upper air tunnel, through two five-way solenoid valve control is easy to operate, also can adjust flow medium. Fluid resistance is small, large caliber of pneumatic valve fully open effective circulation area is larger, easy opening and closing fast, disc pull rotation Angle can complete opening and closing, due to the rotation axis force wrench medium close to equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing, the sealing material is nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, which is suitable for soft hard cascading metal hard seal valve with metal hard seal and elastic sealing advantages, under low temperature circumstances has excellent sealing performance. Working principle of the pneumatic valve is used with the rotating circular plate for opening and closing of the valve orange, enabling action in order to realize the main block valves use pneumatic valve, can be designed to have a adjustment or section of the valve and the adjustment function, disc valve on the low voltage and medium caliber pipe used more and more. Valve has simple structure, small volume, light weight, only by a few parts. And simply rotate ° rapid opening and closing, simple operation, at the same time the electric valve has good flow control characteristics. Valve in the fully open position, the plate thickness is medium flows through the body when the resistance of the single, so by the valve pressure drop is small, it has good flow control characteristics. Valve seal and metal sealing machine has two sealing type. Elastic sealing valve, sealing ring can be embedded in the body or attached to the plate peripheral. If required valve used as flow control, mainly is the right choice of the size and type of valve. The structure of the valve principle, especially suitable for production of large diameter valves. Valve not only in the oil, gas, chemical industry, water treatment and other general industrial used widely, but also applied to the cooling water system of thermal power plants.
