The invention belongs to the technical field of hydraulic valves, and discloses a manual hydraulic valve which comprises a shell. A first cover plate is arranged at one end of the shell; a second cover plate is arranged at the other end of the shell; a valve element is arranged in the shell; and one end of the valve element is elastically connected with one end of a spring. According to the manualhydraulic valve provided by the invention, through arranging a first clamping block and a second clamping block, a valve plate is located between the first clamping block and the second clamping block, a threaded rod is rotated through a handle so as to drive a sliding block to move towards one side, the sliding block drives the second clamping block to be close to one side of the valve plate, the handle continues to be rotated, the valve plate is clamped through the first clamping block and the second clamping block, and when the valve plate is fixed and disassembled, the handle is rotated,the handle drives the sliding block to move towards one side through the threaded rod, the sliding block drives the second clamping block to be away from the valve plate, and the valve plate can be taken down by loosening the valve plate through the first clamping block and the second clamping block; and through clamping and fixing, installation and maintenance are more convenient and faster, andefficiency is higher.
Description
technical field [0001] The invention belongs to the technical field of hydraulic valves, in particular to manual hydraulic valves. Background technique [0002] Hydraulic pressure is a term in the mechanical industry and the electromechanical industry. Hydraulic pressure can be used as a power transmission method to become a hydraulic transmission. Hydraulic pressure can also be used as a control method called hydraulic control. Hydraulic transmission uses liquid as the working medium, and uses the pressure energy of the liquid to transmit power. Hydraulic control is a control that uses pressure liquid as a control signal transmission method. The control system composed of hydraulic technology is called hydraulic control system. Hydraulic control usually includes hydraulic open-loop control and hydraulic closed-loop control. Hydraulic closed-loop control is also hydraulic servo control, which constitutes a hydraulic servo system, usually including an electro-hydraulic s...
