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.
Air-controlled sand control valve At the same time, in order to solve the phenomenon that the core of the sand control valve is hardened due to the excessively fine sand particles or long-term non-use of some high-pressure sand blasting machines, we provide a manual control butterfly sand control valve. This butterfly valve 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. It is a common option for foreign sand blasting machines and suitable for large-scale continuous sand blasting projects.
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 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, at this time the spring return function will work, and the spring return will close the regulating valve. The air-closed pneumatic regulating valve is closed after ventilation.
