[0002] Hydraulic control valves refer to the components used to control the pressure, flow and direction of fluids in hydraulic transmission systems or hydraulic control systems. In automotive braking systems, hydraulic control valves are often used to control the lifting and parking of cars. Brake, exhaust brake, etc.; the valve stem of the existing automotive hydraulic control valve directly cooperates with the valve core to drive the valve core to move, but once the valve core is filled with pressure liquid, its torque will increase significantly, so when cutting off the liquid When circulating, it needs to apply a large force to the valve stem to drive the movement of the valve core. The operation is laborious and inconvenient to use. It needs further improvement.

The invention relates to an automobile hydraulic control valve which comprises a valve body, a valve cover, a valve block, a valve element assembly and an opening and closing assembly. The valve deck and the valve block are detachably fixed to the upper side and the lower side of the valve body respectively, the opening and closing assembly is arranged in the valve deck and the valve body, and the valve element assembly is arranged in the valve block and matched with the opening and closing assembly. The traction rod drives the traction column to swing with the pin as the fulcrum, then the valve element is driven to move, the torque needed for driving the valve element to move is greatly reduced, and therefore when liquid circulation is cut off, the knob can be rotated only with small force to drive the valve element to move, operation is labor-saving, and use is convenient.
