Guiding type solenoid valve: principle: electricity, electromagnetic energy to the guide hole open and chamber pressure on a sudden loss, low in close formation around a high differential pressure, fluid pressure push close a progressive movement, the valve open; Power off, the spring force to close the guide hole, inlet pressure rapidly-changing chamber through the bypass hole under the closed valves on the enclosed form and low high differential pressure, fluid pressure push close move down, close the valve. Spread the direct acting solenoid valve: principle: it is a direct acting and pilot operated the principle of phase conjugation, when the inlet and outlet no pressure difference, after electrify, electromagnetic energy the pilot valve and main valve closed directly to a progressive aspirant, open the valve. Solenoid valve is used to curb the hydraulic flow direction, industrial machinery are made by hydraulic steel stem, so I would use the solenoid valve. Q: office principle of the pneumatic solenoid valve a: electromagnetic valve is used to restrict fluid semi-automatic based components, belonging to actuators; Is not limited to hydraulic, pneumatic. So after a Marine valve stem electric magnet current stem the mechanical movement. Direct acting solenoid valve: principle: electricity, electromagnetic coil initiation electromagnetic energy security barrier closed from the seat, the valve open; Power, the electromagnetic energy away, press on the seat, spring guard barrier closed valve shut off. Office principle of electromagnetic valve, electromagnetic Industrial Valves are tightly closed cavity, in the different position of the hole, every hole leads to different tubing, middle cavity is valve, both sides is two pieces of electric tool, which the magnet coil electricity will be attracted to the body which side, restrict the movement of the valve body to blocked or leakage of different discharge of oil hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push oil just the pistons, piston and help and piston rod, piston rod help and mechanical devices. Unique place: in a vacuum, negative pressure, can normal office when the zero pressure, but not more than 25 mm size ordinary. Unique place: when the zero differential pressure or vacuum and high pressure can also can be action, but power is larger, requirements must be water there is no danger. Trace the history of the progress of the solenoid valve, until up to now, the inside and outside of the electromagnetic valve in principle can be divided into three categories: ( I. e. , straight acting, step by step child guiding type) , and from the disc on the structure and material is different with the difference 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) 。 When entrance and differential pressure of the export to begin to work, after electrify, electromagnetic energy pilot valve, main valve inferior vena pressure rise, the cavity pressure loss, therefore using differential pressure pushed the main valve aspirant away; Power outages, pilot valve using the spring force or medium pressure push off, move down, to close the valve. Unique place: maximum high fluid pressure range, can be arbitrary installation ( Need to customize) But make sure you satisfied fluid differential pressure conditions. 。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
