Abstract

The invention discloses a high-pressure three-position valve which is composed of a valve body, a valve bush, a valve rod, a return base, a spring, a spring base, a connecting rod, a piston, a guide headstock, a guide head assembly and a coil. The valve bush is arranged in the center inside the valve body, sealing between the valve body and the valve bush is achieved through a sealing ring, the two ends of the valve bush and the valve body are positioned through a gasket, the gasket is arranged in the valve body, and the valve rod which can move back and forth in the valve bush is arranged in the center inside the valve bush. A first working air pressure opening, a second working air pressure opening, a control air pressure opening and an air exhaust opening are formed in the bottom of the valve body in sequence, two air ports are formed in the upper portion of the valve body, and a working cavity is arranged above the two air ports. The high-pressure three-position valve has the advantages that a working air path and a control air path are separated; the working path sealing is metal clearance gap sealing; four functions are provided; the structure is compact, size is small, and combination is convenient; the service life is long, reaction is sensitive, and the reversing action is fast.

Description

technical field [0001] The invention relates to the field of solenoid valves, in particular to a high-pressure three-position valve. Background technique [0002] The existing high-pressure three-position valve is composed of three two-position two-way diaphragm solenoid valves. During the design process, the working air path and the control air path are not separated, and there are still problems such as large volume, inconvenient combination, slow response, and long service life. Not long flaws. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-pressure three-position valve with compact structure, small volume and easy assembly. [0004] The object of the present invention is accomplished through the following technical scheme, which is composed of valve body, valve sleeve, valve stem, return seat, spring, spring seat, connecting rod, piston, pilot head seat, pilot head ass...
