Abstract

The invention discloses a hydraulic electromagnetic valve which comprises electromagnetic assemblies, a valve body, a valve sleeve, a valve core and rubber rings, wherein a through hole is formed in the valve body; the valve sleeve is arranged in the through hole of the valve body; the valve core is arranged in the valve sleeve; the electromagnetic assemblies are arranged at two ends of the through hole of the valve body; the electromagnetic assemblies informs that the valve core moves in the valve sleeve; the rubber rings are arranged at two ends of the valve sleeve; and springs for compressing the rubber rings are arranged between the rubber rings and the electromagnetic assemblies. The rubber rings and the springs are arranged between the valve sleeve and the electromagnetic assemblies; the springs supply pressure to the rubber rings; due to the pressure supplied by the springs, the rubber rings and pieces which are in contact with the rubber rings can be in close contact, so that the phenomenon of oil leakage can be avoided; furthermore, by the arrangement of the valve sleeve, damage to the hydraulic electromagnetic valve due to the friction generated by the valve core and the valve body during work is effectively prevented; and the valve body is effectively protected.

Description

technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to a hydraulic solenoid valve. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetism. It is an automatic basic component used to control fluid and belongs to actuator. It is used in the industrial control system to adjust the direction, flow, speed and other parameters of the medium, which has the advantages of high precision and flexibility. At present, the sealing effect of the seal between the spool and the electromagnetic assembly of the hydraulic solenoid valve in the prior art is not good, and oil leakage will occur after a period of use, resulting in damage. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a hydraulic solenoid valve with good sealing effect and no oil leakage. [0004] In order to solve the above technical problems, the technical solution of the p...
