Two-position four-way electromagnetic ball valve

Abstract

The invention discloses a two-position four-way electromagnetic ball valve. The two-position four-way electromagnetic ball valve comprises a valve shell, wherein a bottom plate is fixedly arranged atan opening in the lower end of the valve shell, a convex column which extends upwards into the valve shell is arranged in the center of the bottom plate, and a convex ring is fixedly arranged on the bottom plate by taking the convex column as the center; convex edges which abut against the side wall of the inner ring of the convex ring are symmetrically arranged on the side surface of the convex column; a central cavity with an opening in the upper end is formed in the convex column, a left cavity and a right cavity are formed between the outer side of the circumference of the convex column and the side surface of the inner ring of the convex ring, a first annular cavity is formed in the convex ring, and a port P communicating with the central cavity, a port A communicating with the left cavity, a port B communicating with the right cavity and a port T communicating with the first annular cavity are formed in the bottom of the bottom plate; and the convex ring is provided with a left valve element assembly and a right valve element assembly, and a valve control assembly used for controlling the left valve element assembly and the right valve element assembly to work is arranged inthe valve shell. The two-position four-way electromagnetic ball valve is simple in structure, compact in size and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic ball valves, in particular to a two-position four-way electromagnetic ball valve. Background technique [0002] Electromagnetic ball valve is a reversing valve that changes the flow direction of the oil circuit through the opening and closing of the spool sealed by the electromagnet or the motor control line. It relies on the spherical or conical surface to seal and close the oil circuit, with good sealing performance and no internal leakage; Fast, sensitive action; because the valve core is a steel ball or a tapered plunger, there is no axial sealing length, and there will be no hydraulic clamping phenomenon like a slide valve when reversing, which can meet the requirements of high pressure and use high pressure; and The electromagnetic ball valve has strong anti-pollution ability and can adapt to various working media. The electromagnetic ball valve of the prior art has the following te...

AI Technical Summary

Problems solved by technology

[0003] 1. The function of the electromagnetic ball valve in the prior art is relatively single, mainly in the structure of two-position two-way or two-position three-way. The valve is combined, the structure is complex, the volume is large, and the cost is high;

[0004] 2. The electromagnetic ball valve of the prior art needs the electromagnet to be charged all the time when in use, and the power consumption is relatively large, and because the electromagnet is always charged, the coil heats up severely, on the one hand, it will reduce the output force of the electromagnet and affect the sealing performance, and on the other hand On the one hand, it will affect the service life of the electromagnetic ball valve
