Working principle and advantages of pneumatic valve

The working principle and advantages of pneumatic valve, using range is very wide, its main features are: simple structure, small volume, light weight, material, suitable for large diameter valves; Open/close quickly, small flow resistance; Can be used in the medium with suspended solids, based on the strength of the sealing surface can also be used for powder and granular media. Can be used in ventilation and dust removal pipe two-way opening and closing and adjustment, it is widely used in metallurgy, light industry, electric power, petroleum chemical industry system of gas pipeline and channel, etc. Pneumatic valve plate installed on the diameter of the pipe direction. In the cylindrical channels of the valve body, disc plate around the axis of rotation, rotation Angle for ° - Between °, rotate to °, the valve is in the fully open position. 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 valve has good flow control characteristics. Valve in the fully open position, the plate thickness is medium flows through the body when the only resistance, 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.
