How to wire the pneumatic solenoid valve? How to connect the two wires and three heads of the pneumatic solenoid valve?

Knowledge about the use of pneumatic solenoid valves. Pneumatic solenoid valves block or leak different oil drain holes by controlling the movement of the valve body. The oil inlet hole is always open, and the hydraulic oil enters different oil drain pipes. The pressure of the oil through the pneumatic solenoid valve Push the piston in the cylinder. Pneumatic solenoid valve wiring method Wiring method: one in and two out, one is the air intake source, the two out are all the way to the membrane head, and all the way to vent. The solenoid valve installed directly on the pipeline is generally an electric solenoid valve, which can only control two states: on and off. There is a closed cavity in the pneumatic solenoid valve, with through holes at different positions. Each hole of the pneumatic solenoid valve leads to a different oil pipe. There is a valve in the middle of the cavity, and two electromagnets on both sides. Which side of the magnet coil energizes the valve? The body will be attracted to which side. The pneumatic solenoid valve blocks or leaks different oil drain holes by controlling the movement of the valve body, while the oil inlet hole is normally open. The hydraulic oil will enter different oil drain pipes, and the pressure of the oil through the pneumatic solenoid valve will push the oil in the cylinder. piston. In this way, the mechanical movement of the entire solenoid valve can be controlled by controlling the current of the electromagnet of the pneumatic solenoid valve. The wiring method of the pneumatic solenoid valve: connect it to the solenoid coil. There are three points on the solenoid coil. Connect the two points on the left and right. The middle point is not connected. The wiring method of the two wires on the 24V pneumatic solenoid valve is as follows: of the two wires on the 24V gas solenoid valve, one is connected to the input terminal, which is the positive pole, and the other is connected to the output terminal, which is the negative pole. The 24v solenoid valve has three lines, namely the ground line yellow-green, the positive and negative pole lines. If it is connected to AC power, there is no need to consider the positive and negative poles, just connect them directly, and the ground wire is connected to the ground. If the solenoid valve is connected to DC, it is necessary to distinguish the positive and negative poles. Use a multimeter to test the positive pole to ensure that it is the same voltage as the solenoid valve. The positive pole is connected to the positive pole, the negative pole is connected to the negative pole, and the ground wire is connected to the ground wire. The two wires of the 220-volt solenoid valve are not divided into positive and negative poles. Just connect the control power supply to these two wires. The solenoid valve generally uses a single coil. The DCS outputs a DO to control the contact of a relay and connects the power supply in series. The solenoid valve is a control cable. If there is a valve position switch, it is also a control cable, regardless of whether the DCS has a safety barrier or not. The 2-position 5-way solenoid valve has automatic reset and electric reset. The automatic reset only controls one solenoid coil, and the PLC has one output control signal. The electric reset needs to control two solenoid coils, and the PLC needs to have 2 output control signals. How to connect the three heads of the pneumatic solenoid valve to the three wires of the solenoid valve, the positive and negative power wires and the ground wire. If it is alternating current, we directly connect the positive and negative power wires to the two terminals of the power supply without considering the positive and negative poles of the wiring, and the remaining wire is connected to the ground terminal. Usually the terminal blocks will have relevant symbols to distinguish them. If it is DC, pay attention to distinguish the positive and negative poles. The positive and negative wires should be connected to the positive and negative terminals respectively, and the ground wire should be connected to the ground terminal. (Two two-position three-way) pneumatic solenoid valve wiring method: one in and two out. One in is the air intake source, and the two out are all the way to the membrane head and all the way to the vent. The solenoid valves directly installed on the pipeline are generally electric solenoid valves, which can only control There are two types: on and off. The details are as shown in the figure below: The above is the wiring method of the pneumatic solenoid valve. How to connect the two wires and three heads of the pneumatic solenoid valve?
