Abstract

A large-diameter direct-acting high-pressure solenoid valve, including a valve body, a coil cover, a coil, a spring, a valve core, a valve seat and an O-ring, is a coaxial integral structure. The upper part of the solenoid valve is the valve body, and the valve The upper end of the body is a medium inlet connection thread; the middle circle of the valve body is wound with an electromagnetic coil, and the outer side of the electromagnetic coil is a coil cover. Its control method adopts a two-position two-way direct-acting structure, which is opened when the power is turned on and closed when the power is turned off; the fluid medium flows in from the top of the valve body and flows out from the bottom of the valve seat. Compared with the prior art, the present invention has significant advantages: 1. Large diameter, high operating pressure, and long continuous energization time, so it can continuously and stably provide large flow medium; 2. Fast action response speed (≤10ms), The electromagnetic coil of the electromagnetic valve is relatively large, and the cross-sectional area of ​​the valve core is also relatively large, which can generate a large electromagnetic suction force, so the response speed is very fast.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to a large-diameter direct-acting high-pressure solenoid valve. Background technique [0002] At present, domestic high-pressure solenoid valves with large diameters generally adopt a pilot-operated (unloading) structure, that is, when the power is turned on, the electromagnetic force opens the pilot valve core, and the pressure in the upper chamber drops rapidly, forming an up-down and down-high structure around the valve core. Pressure difference, the fluid pressure pushes the valve core to move upward, and the valve opens; when the power is off, the spring force closes the pilot hole, and the inlet pressure quickly passes through the bypass hole. On a high pressure differential, fluid pressure pushes the closure member down, closing the valve. The pilot solenoid valve has the characteristics of large diameter and high operating pressure, but the response speed of the solenoid valv...
