Abstract

The invention provides a pilot control hydraulic one-way valve. The pilot control hydraulic one-way valve comprises a valve sleeve, a main valve core and a main spring; a radial hole is formed in the main valve core; a water outlet is formed in the valve sleeve; a cover plate is arranged at the top end of the valve sleeve; the main spring is fixed to the bottom surface of the cover plate; a plurality of through holes of which the upper ends are plugged are formed in the cover plate; an annular groove is formed in the centre of the cover plate to communicate the through holes to form an accommodating cavity; a draining hole is formed in the cover plate; the top of the cover plate is connected with a pilot valve body; a pilot valve core is arranged in the pilot valve body; a pilot spring is arranged on the pilot valve core in a sleeving manner; the bottom end of the pilot valve core extends into the accommodating cavity; an electromagnetic coil is arranged at the top end of the pilot valve body; a pole shoe is arranged between the pilot valve body and the electromagnetic coil; an armature is arranged in the electromagnetic coil; the end part of the armature penetrates through the pole shoe to be in contact with the top end point of the pilot valve core. The pilot control hydraulic one-way valve is simple in structure; the pilot valve core is closed or opened by controlling the on-off state of the power of the electromagnetic coil, so that the on-off state among a water inlet, the water outlet and a draining hole is controlled; therefore, combination control of liquid flowing directions and control of automatic flow distributing protecting function are realized.

Description

technical field [0001] The invention belongs to the technical field of hydraulic valves, and specifically relates to a pilot control hydraulic check valve, which is suitable for water hydraulic systems using seawater, fresh water, high water base, etc. as working media, and can be widely used in intelligent hydraulic loading, water cleaning, water Pressure force system and other fields. Background technique [0002] Check valve is a commonly used directional control element in hydraulic system, mainly used to control the connection or cut-off of fluid medium in hydraulic system in a specific direction. In the traditional hydraulic system using hydraulic oil as the working medium, the use of check valves is very mature, used for the outlet of the pump, the inlet of the actuator, etc., but in the water hydraulic system using seawater, fresh water, high water base, etc. The special physical and chemical properties of water will bring a series of problems: ①The viscosity of wat...
