HMB

A hydraulic manifold, it will a group of suction check valve (4), a group of pilot operated check valve, a group of overflow check valve, a pressure relief valve integrated through hydraulic couplings the oil passage. It is one-way valve and pressure relief valve with overflow, which with the oil pipe (14) communicated to the pressure control to the desired value. It has a check valve, when the system stops working, the control oil pressure also decreased, while closing the check valve, make parts quickly stop the movement, from the self-locking effect. The utility model has small size, used in hydraulic drive device is easy to install, making stand-alone compact structure.
Sovereignty items
Claims 1, to a hydraulic manifold, it mainly consists of housing, oil inlet (1), the oil port (2) as well as oil passageway composition, wherein the inlet (1) and the inlet pipe (12) showed a communicating state, the inlet duct (12) ends of the two suction check valve (4) hose assembly in the inlet was communicating state, each of the suction check valve (4) and the oil outlet pipe, respectively, with the pump (13) was connected state, the pump tubing (13) and the oil pipeline (14) was connected states, each of the oil pipeline (14) and check valve (5) is connected to the inlet pass, check valve (5) out of the oil port and manifold outlet port (2) was connected state, each of the oil pipeline (14) and the overflow check valve (6) is connected to the inlet pass, each overflow unidirectional the valve (6) of the oil outlet and the overflow pipe (17) connected to pass, each of the overflow pipe (17) and the pressure relief valve (7) showed the inlet communicating state, relief valve body and the overflow Movement connectivity status.
