Abstract

The invention discloses a semiautomatic manual hydraulic valve which comprises a valve casing, a valve element, a handle and a spring. The valve element is mounted in the valve casing. The spring is mounted at one end of the valve element. The handle is mounted at the other end of the valve element. The spring is located between the valve element and the valve casing. According to the semiautomatic manual hydraulic valve, the flow direction can be conveniently and fast switched through the handle, in addition, the valve element can be automatically returned without control of the handle, and it is guaranteed that a reversing valve is in a closed state.

Description

technical field [0001] The invention relates to the field of reversing valves, in particular to a semi-automatic manual hydraulic valve. Background technique [0002] The reversing valve is a directional control valve with more than two flow forms and more than two oil ports. It is a valve that realizes communication, cutting and reversing of hydraulic oil flow, as well as pressure unloading and sequential action control. Manual reversing valves are often used in hydraulic control systems to manually control the flow direction of hydraulic oil. However, the existing manual reversing valve has a single structure and cannot solve some common problems while using the manual reversing valve. Contents of the invention [0003] (1) Technical problems to be solved [0004] Aiming at the deficiencies in the prior art, the present invention provides a semi-automatic manual hydraulic valve. [0005] (2) Technical solutions [0006] In order to achieve the above object, the prese...
