The solenoid valve is an electromagnetically controlled industrial device. It is an automatic basic component used to control fluids. It is an actuator, and a pneumatic solenoid valve is one of them. It controls the movement of the valve body to block or leak different oil discharges. The hole, while the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then the piston of the oil cylinder is pushed by the pressure of the oil of the pneumatic solenoid valve, so that the current of the electromagnet controlling the pneumatic solenoid valve is controlled. The mechanical movement of the entire solenoid valve. 1. It can work normally under vacuum, negative pressure and zero pressure, but the diameter is generally no more than 25 mm. 2, can also be operated in the case of zero differential pressure or vacuum, high pressure, but the power is large, the requirement must be installed horizontally. 3, the upper limit of the fluid pressure range is high, can be installed arbitrarily (customized), but must meet the fluid pressure difference conditions. 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. Which side the valve body will be attracted to; The pneumatic solenoid valve blocks or leaks different oil drain holes by controlling the movement of the valve body, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then the pressure of the oil through the pneumatic solenoid valve Pushing the piston of the oil just like this, the mechanical movement of the entire solenoid valve is controlled by the current of the electromagnet controlling the pneumatic solenoid valve. The working position of the pneumatic solenoid valve (the solenoid valve is opened or closed) is actually the position of the spool 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 (on or off), 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 of one in and two out, and the two out channels are respectively 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. The wiring of the solenoid valve product is relatively simple. Generally, the power cord of the solenoid valve has three wires: the ground wire, the positive pole and the negative pole. If it is an alternating current, the positive and negative poles of the wiring can be ignored. If it is direct current, it is necessary to pay attention to the positive and negative poles, and Pay attention to the same voltage.
