Hydraulic joint for hydraulic valve

Abstract

The invention provides a hydraulic joint for a hydraulic valve, and relates to the technical field of hydraulic joints. The hydraulic joint for the hydraulic valve comprises a joint pipe body, whereinthe joint pipe body comprises a connecting pipe which is inserted into the upper end of the joint pipe body and communicates with the joint pipe body; a threaded groove communicating with the connecting pipe is formed in the upper surface of the connecting pipe; an inserting pipe communicating with the connecting pipe is inserted into the tail end of the connecting pipe; an inserting hole communicating with the inserting pipe is formed in the center of the bottom of the inner surface of the inserting pipe; a piston pipe is embedded into the inserting hole; a first rubber ring and a second rubber ring are bonded to the tail end and the top end of the piston pipe correspondingly; connecting blocks are symmetrically welded to the left side and the right side of the inner wall of the inserting pipe; the right ends, far away from the inner wall of the inserting pipe, of the two connecting blocks are rotationally connected with inclined rods through rotating shafts; spring rods are welded to the middle positions of the inclined rods; and the tail ends of the inclined rods are rotationally connected with vertical rods through rotating shafts. The hydraulic joint has the beneficial effects that the single-double-stop circulation requirement of a user is met, and the sealing performance of the joint is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic joints, in particular to a hydraulic joint used for hydraulic valves. Background technique [0002] Hydraulic pipe joints are formed by connecting different hydraulic components (pumps, delivery lines, reversing valves, globe valves, hydraulic motors, hydraulic cylinders, and some auxiliary components, such as liquid level gauges, thermometers, pressure gauges, etc.) A closed circuit hydraulic system is an accessory that acts as a connection. [0003] Existing hydraulic joints for hydraulic valves are usually difficult to satisfy both one-way and two-way circulation according to actual needs when one-way circulation is satisfied, resulting in the need for users to purchase different hydraulic joints according to different needs, thereby increasing the cost of use , and the connection between the joint and the device is more general. Contents of the invention [0004] The technical problem to...
