principle:
There are closed chambers in the pneumatic solenoid valve. There are through holes in different positions. Each hole of the pneumatic solenoid valve leads to different oil pipes. The middle of the cavity is a valve. On both sides are two electromagnets. Which side of the magnet coil is energized. The valve body will be attracted to which side; the pneumatic solenoid valve will block or leak different oil drain holes by controlling the movement of the valve body, and the oil inlet hole is normally open, and the hydraulic oil will enter different oil discharge pipes. Then, the oil piston is pushed by the pressure of the oil of the pneumatic solenoid valve, so that the mechanical movement of the entire solenoid valve is controlled by controlling the current of the electromagnet of the pneumatic solenoid valve.
Operating principle of pneumatic solenoid valve
The working position of the pneumatic solenoid valve (the solenoid valve is opened or closed) is actually the position of the valve core of the pneumatic solenoid valve.
The spool is in the A position when the coil is not energized and in the B position when the coil is energized. When the spool of the pneumatic solenoid valve is in different positions, the interfaces on the valve body are either turned on or off. For example, a two-position solenoid valve means that the spool of the solenoid valve has two different working positions (open or closed), and for the pneumatic solenoid valve, the solenoid valve is charged and de-energized; for the valve it controls It is the opening and closing of the valve. The two-way and three-way solenoid valves refer to two or three passage ports on the valve body of the pneumatic solenoid valve. The two-position two-way solenoid valve has two channels of one in and one out, which is the most common pneumatic solenoid valve; the two-position three-way solenoid valve is three channels that enter and exit, and the two out channels are corresponding The connection is normally open and normally closed. Similarly, the three-way, four-way, and five-way also refer to the number of fluid passages on the valve body.
