Stainless steel solenoid valve price | stainless steel solenoid valve size | stainless steel solenoid valve works | the role of stainless steel solenoid valve solenoid valve history, so far, at home and abroad from the principle of stainless steel solenoid valve is divided into three categories (ie: direct-acting step by step direct-acting, pilot operated), and from the valve on the different structures and materials with the principle difference between the branch is divided into six subclasses (direct-acting diaphragm structure, step by step membrane structure, membrane pilot sheet structure, direct-acting piston structure, step by step piston structure, the pilot piston structure). (A), stainless steel solenoid valve direct-acting principle: power, the electromagnetic coil of electromagnetic force to lift off pieces from the seat, the valve open; power, the electromagnetic force disappears, the spring force to close the piece down on the seat , the valve closes. Features: In a vacuum, negative pressure, zero pressure can work, but the general diameter of not more than 25mm. (B), step by step stainless steel solenoid valve direct-acting principle: it is a direct-acting and pilot a combination of theory, when the inlet and outlet pressure ≤ 0.05Mpa, electricity, the electromagnetic force directly to the small pilot valve and main valve closure member in turn lift the valve open. When the inlet and outlet pressure> 0.05Mpa, electricity, the electromagnetic force the first small open pilot valve, main valve chamber under increased pressure, the chamber pressure drops, thus the use of pressure to open up the main valve; power, the pilot valve and the main valve spring force or the use of medium pressure to promote off pieces, moving down, the valve closes. (C), stainless steel solenoid valve pilot principle: power, the electromagnetic force to open the pilot hole, the chamber pressure to drop rapidly in close formation around the lower parts of high pressure, push off pieces to move up, the valve opens; energized, the spring forces the pilot hole is closed, the inlet pressure through the bypass hole quickly into the chamber formed around the valve off on the high-low under the pressure, push off pieces down, close the valve.
