Electromagnetic valve fault maintenance

Magnetic valve solenoid valve fault maintenance time is composed of electromagnetic coil and core, consists of one or a few holes of the body. When the coil electricity or without electricity, magnetic core operation will lead to flow through the valve body or is cut off, in order to change the direction of flow. Electromagnetic valve electromagnetic components by the fixed core, moving iron core, coil components such as solenoid valve is composed of electromagnetic coil and core, consists of one or a few holes of the body. When the coil electricity or without electricity, magnetic core operation will lead to flow through the valve body or is cut off, in order to change the direction of flow. Electromagnetic valve electromagnetic components by the fixed core, moving iron core, coil and other parts; Body parts by a valve core, valve cover, spring base, etc. The electromagnetic coil is directly installed on the valve body, the body is enclosed in a sealed tube, constitute a combination of a simple, compact. We commonly used in the production of the solenoid valve have two three links, two cross, two five. Here to talk about the meaning of the two for electromagnetic valve is charged with electricity, for the control valve is opened and closed. Working principle of electromagnetic valve and troubleshooting working principle of the solenoid valve solenoid valve at home and abroad in principle can be divided into three categories: ( Namely, straight acting, step by step straight acting, guiding type) , and from the disc structure and material of different and the difference on the principle is divided into six branches small class ( Diaphragm structure, step by step of moving heavy piece of membrane structure, the structure, the forerunner in straight moving piston structure, step by step piston structure, the forerunner of moving piston structure) 。 Classification and characteristics of direct acting solenoid valve principle of electricity, the electromagnetic coil to produce electromagnetic force to shut down from the seat lift, the valve opening; Power, the electromagnetic force disappears, press on the seat, spring to close the valve closed. Characteristics in a vacuum, negative pressure, can work properly when the zero pressure, but size is generally not more than the mm. Step by step direct acting solenoid valve principle it is a direct acting and pilot operated the principle of combining when the inlet and outlet no pressure difference, after electrify, electromagnetic force directly combine small pilot valve and main valve closed in lift, the valve opens. When the inlet and outlet at startup pressure difference, after electrify, the electromagnetic pilot valve, main valve inferior vena pressure rising, the cavity pressure drop, which using differential pressure to the main valve opened up; Power cuts, pilot valve using the spring force or medium pressure push off, move down, to close the valve. Characteristics on the zero differential pressure or vacuum and high pressure, to action, but power is larger, requirements must be installed level. Principle guiding type solenoid valve power, the electromagnetic force open the pilot hole, the chamber pressure drops rapidly, in closed form around the high low differential pressure, fluid pressure push close up, the valve open; Power off, the spring force to close the guide hole, inlet pressure chamber through the by pass hole quickly in closing valve using a form around the high differential pressure, fluid pressure push close move down, close the valve. The upper limit characteristics of the fluid pressure is higher, can be arbitrary installation ( Need to customize) But fluid differential pressure conditions must be met. Solenoid valve factory is a set of solenoid valve design, research and development, manufacture, testing, installation as one of the high-tech entity enterprise, consultation telephone order
