How to wire the solenoid valve, instructions for wiring the solenoid valve

How to wire the solenoid valve? Description of the solenoid valve wiring method. The wiring method of the solenoid valve is actually the simplest type among all automatic control valves. Normally, there are only two wiring methods we come into contact with, lead type and junction box type. How about the solenoid valve? Wiring, summarize how to wire the solenoid valve in an easy-to-understand way. 1. According to the type of wiring, there are two types of commonly used solenoid valve wiring, lead type and junction box type. The principle is the same. The lead type actually means to unplug the junction box plug and connect a power cord from inside the coil. It has become integrated;1. Lead type;mostly used in waterproof and explosion-proof (explosion-proof) types. The advantage is that the lead can be directly connected to the control system. The disadvantage is that if it is far away from the control system, new wiring is required;2. Wiring Box type;currently the most popular is this wiring method, which uses DIN connectors. No matter how far away the control system is, it will not be affected, there will be no broken lines in the middle, and there will be no additional nodes. 2. According to the type of coil, there are three common types: single coil switch control (90% of the market is this type), single coil self-retaining type and double coil self-retaining type;1. Single coil switch control type wiring, This is the most common, whether it is lead type or junction box type, there are three wires;① If it is direct current, such as DC24V control, the positive pole, negative pole and ground wire, regardless of the positive and negative poles, remember not to distinguish the positive and negative poles ! ②. If it is AC control such as AC220V, the neutral wire, live wire and ground wire are not divided into zero and live wires. Similarly, there is no distinction between zero and live wires. 2. Single coil self-maintaining control type solenoid valve wiring;this is only used for DC control. System, three wires, respectively A, B, C, of ​​which B is the common terminal;①, A is connected to the positive pole, B is connected to the negative pole, the solenoid valve is open, and the solenoid valve remains open after power is cut off. At this time, the solenoid valve does not need to use electricity. Maintenance;②, C is connected to the positive pole, B is connected to the negative pole, the solenoid valve is closed, and the solenoid valve remains closed after power failure. Similarly, the solenoid valve does not consume power at this time;Note: Single coil self-maintaining solenoid valves are mostly used for long-term work and insufficient power. in the pulse control system. 3. Double-coil self-holding control type wiring;the control principle is the same as the single-coil self-holding type, except that this one uses independent coil control of switches, which is mostly used for pulse control in the fields of high-temperature solenoid valves and high-pressure solenoid valves;equivalent to two The wiring of the single coil switch control type is just one coil controlling one state. The valve will maintain its state after power is cut off. The moment the top coil is energized - the solenoid valve opens, and the moment the side coil is energized - the solenoid valve closes. 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 pneumatic piston actuator uses compressed air as the power source, and drives the crank arm to rotate ninety degrees through the movement of the piston to achieve the purpose of automatically opening and closing the valve. The components of a pneumatic valve mainly include adjusting bolts, actuator box, crank arm, cylinder block, cylinder shaft, piston, connecting rod, universal shaft, etc. The above is an introduction to how to wire the solenoid valve and the instructions for wiring the solenoid valve.
