Embodiment Construction

[0015] Such as figure 1 Shown, the present invention is made up of electromagnet 1 and check valve. The one-way valve includes a valve body 3, a valve core 4 and a snap ring 7; an oil port A is opened on one side of the valve body 3, and an axial through hole is opened in the axial direction of the valve body 3, and the middle is a joint One side of the throttle hole is oil port A, and the axial through hole of the valve body 3 on the other side of the throttle hole is equipped with a valve core 4 and a retaining ring 7 in sequence from the inside to the outside, and the hole end is an oil port. Port B, the spool 4 is stepped, the tapered surface of the small end of the spool 4 matches the orifice, and the side of the small end of the spool 4 has a hole connecting the inner hole of the spool 4 and the axial through hole of the valve body 3 Oil hole; the electromagnet push rod 2 of the electromagnet 1 is housed in the axial through hole of the valve body 3 on one side of the t...

Abstract

The electrically controlled one-way valve consists of electromagnet and one-way valve, and the one-way valve includes valve body, valve core and jump ring. The valve body has oil port A on one side, axial through hole, middle throttle hole, stepped valve core with small end fitting the throttle hole, jump ring and oil port B. The electromagnet push rod mounted inside axial through hole in the valve body can contact with the small end of the valve core. The present invention can realize the pressure maintaining one-way valve function and reverse motion under the control of electric signal.

Description

technical field [0001] The invention relates to a directional control valve in the technical field of fluid transmission, in particular to an electronically controlled one-way valve. Background technique [0002] Directional control valves in the field of fluid transmission include check valves, hydraulic control check valves, electromagnetic directional valves, electro-hydraulic directional valves and other types. Check valve, also known as check valve or check valve, has two oil ports in its structure, and its function is to allow fluid to pass in only one direction, but not reverse flow. The check valve is usually used as a pressure maintaining valve, or placed at the outlet of the pump to prevent damage to the pump when the pressure suddenly rises, and it can also be used as a back pressure valve. The hydraulic control check valve is to increase the hydraulic control part on the ordinary check valve. There are three oil ports in the structure. The added oil port is call...
