An Angle-Adjustable Hydraulic Sliding Valve Control Disengagement Mechanism

Abstract

The invention relates to an angle-adjustable trip mechanism for controlling a hydraulic slide valve. The trip mechanism comprises an outer rocker arm (1), a bow spring (2), a lower steel ball (3), a spring piece group (4), a bow spring pressing nut (5), a spring piece group pressing nut (6), steel ball base (7), an upper steel ball (8), a middle screw (9), an upper screw (10), a spline supporting arm (11), a shaft sleeve (12), a space ring (13), a small steel ball (14), a spline shaft (15), an anti-thrust base (16) and a lower screw (17). The trip mechanism disclosed by the invention is capable of releasing a control force when the slide valve is blocked and realizing precise regulation on zero position of the hydraulic slide valve; the overall mechanism is enough in rigidity when acting as a whole body.

Description

technical field [0001] The invention belongs to the field of hydraulic engineering, and relates to a hydraulic sliding valve control mechanism with an angle adjustment structure and a disengagement reset structure. Background technique [0002] In the design process of the hydraulic spool valve control mechanism, ordinary connecting rods are often used. Once the spool valve is stuck, when the control mechanism continues to exert force on the spool valve, it is easy to cause precise and expensive spool valves. damaged severely. However, the setting of electronic detection or protection circuit breaker for the spool sticking phenomenon of the hydraulic spool valve control mechanism is often controlled, which is relatively difficult and expensive. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art. In the hydraulic spool valve operating mechanism, the function of disengaging and resetting the mechanism is added, and at the sa...
