Abstract

The invention discloses a multifunctional integrated valve block of a hydraulic drive, which comprises a cuboid valve body and a three-position four-way solenoid valve; the upper end surface of the valve body is provided with an oil inlet port ferrule joint, an oil return port ferrule joint and A cut-off needle valve, with a B-way throttle valve on the left side and an A-way throttle valve on the right side; B-way relief valve, A-way relief valve, oil outlet, return Oil port; the valve body is equipped with B-way hydraulic control check valve and A-way hydraulic control check valve; oil line B and oil line A are arranged in the valve body; oil line B is between the oil inlet ferrule joint and the oil outlet Two oil circuits connected in parallel between the ferrule joint of the oil return port and the oil return port are respectively provided in the oil circuit A: the speed regulating oil circuit and the overflow oil circuit; the oil outlet and the return port of the three-position four-way solenoid valve The oil port is respectively connected with the ferrule joint of the oil inlet port and the ferrule joint of the oil return port. The invention has the advantages of simple structure, small volume, convenient installation and operation, can significantly reduce oil leakage, and can realize multiple functions.

Description

technical field [0001] The invention belongs to the field of hydraulic systems, and in particular relates to an integrated valve block for a valve hydraulic driver. Background technique [0002] The hydraulic oil circuit used for the valve hydraulic actuator has a complex structure, large volume, many connection points, and is prone to technical problems such as oil leakage, which is not convenient for operators to install and maintain. [0003] The integrated valve block is used to simplify the piping arrangement of the hydraulic system. In the installation and piping of the valve block, various components should be distributed as compactly and evenly as possible on all sides of the valve block body. Aesthetic requirements must be met, and layout schemes together with connectivity requirements are the starting conditions for channel design. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention proposes a multifunctional int...
