Solenoid valve is a solenoid-controlled industrial equipment, by adjusting the medium in the direction of industrial control systems, flow, speed, and other parameters. Solenoid valve can be used with different circuits to achieve the desired control, and precision control and flexibility are able to guarantee. There are many solenoid valve, the solenoid valve play different roles in different position control system, the most commonly used is a one-way valve, safety valve, directional control valve, the speed control valve. Working principle of electromagnetic valve in a sealed chamber, at different locations with holes, each hole leads to a different pipeline, the middle chamber is a valve, two is two electromagnets, which faces the magnet coil is energized the valve will are attracted to which side, by controlling the movement of the valve body to block or leaked oil discharge hole different, and into the hole is always open, the hydraulic oil goes into a different outlet pipe, and then to push through the pressure of the oil tanks piston, the piston rod has led rod drive mechanism moving. Thus by controlling the solenoid off electrical current to control the mechanical movement. New multi-function valve installed pipe: both manual functions, eliminating three manual valves, online service, greatly reducing costs. 1, medium viscosity scope adjustable: adjustable to achieve gas, water, oil, GM, facilitate the procurement, storage, installation and maintenance. 2, the valve open and close time is adjustable: to meet various requirements, effectively prevent water hammer damage. 3, the valve opening can be adjusted: maximum and minimum opening can be preset to improve the accuracy of automatic control. 4, the main valve wear can compensate :: extend valve life, and withstood the test of time. 5, diameter: DN1-DN1200. 6, temperature: -196-450 ℃. Structural principle of the pilot solenoid valve cleverly valve, manual valve and the throttle valve combination in one, driven by the main valve action after the pilot accept electrical switch. Adjusting screw A, B can be adjusted medium viscosity range of application and the main valve switching time, and after the main valve to compensate for wear. Pilot valve repair takes just tighten the adjustment screws B and isolation screw C, can be removed and used manually screw operation. The screw can also be used to preset a maximum or minimum flow rate solenoid valve automatic control. 1. The solenoid valve is divided into three categories from the principle of: 1) direct-acting solenoid valves: principle: power, the electromagnetic coil generates an electromagnetic force to close the piece is lifted from the seat, the valve opens; when power is off, the electromagnetic force disappears spring the closure member is pressed on the seat, the valve closes. Features: Can work in a vacuum, negative, zero pressure, but the path is generally not more than 25mm. 2) step direct-acting solenoid valves: principle: it is a direct-acting and pilot-combining principle, when there is no pressure inlet and outlet, the power, the electromagnetic force directly to the pilot valve and main valve closure member Lift turn, the valve opens. When the inlet and outlet reaches the starting pressure, the power, the electromagnetic force pilot valve, the main valve chamber under increased pressure, the chamber pressure drops, to take advantage of the upward pressure of the main valve open; power, the pilot valve spring force or medium pressure to promote off pieces, moving down, the valve closes. Features: zero pressure or vacuum, high pressure can also be * action, but power is larger, requirements must be mounted horizontally. 3) Pilot solenoid valves: principle: power, the electromagnetic force open the pilot hole, the chamber pressure decreased rapidly around the closure of parts of high pressure on the lower formation, the fluid pressure to promote off pieces to move up, the valve opens; break electricity, the spring force of the pilot hole closed, the inlet pressure chamber through the bypass hole quickly shut the valve member is formed around the low pressure on the high fluid pressure to promote off pieces moving down, close the valve. Features: high fluid pressure upper limit can be any installation (to be customized) but fluid pressure conditions must be met. 2. The solenoid valve with the principles from the difference between the different structures and materials on the on the branch is divided into six categories: direct-acting diaphragm structure, step by step direct-acting diaphragm structure, the pilot diaphragm structure, direct-acting piston structure, step direct-acting structure, the pilot piston structure of the piston.
