Brief description of the role of air control sand control valve


The air control sand control valve controls the size of the sand output. The main replacement parts inside are rubber cores, which are made of wear-resistant rubber, which is durable, easy to replace and cheap.
At the same time, the air-controlled sand control valve is used to solve the phenomenon that the rubber core of the sand control valve is hardened due to the excessively fine sand particles or long-term non-use. It adopts inclined sand production to overcome the resistance caused by the vertical sand falling of ordinary sand valves. The sand pipe is easy to block sand. It is suitable for the use of fine sand.
The single-acting cylinder has a spring return function, and the pneumatic regulating valve can choose air-open type and air-close type according to the needs of the working conditions. The initial state of the regulating valve is closed, commonly known as "air-opening". Similarly, if the initial state of the regulating valve is open-commonly known as "air-closing", the air-opening pneumatic regulating valve is opened after ventilation. Disconnected, the spring return function will work at this time, the spring reset will close the regulating valve. The air-closed pneumatic regulating valve is closed after ventilation.
