Embodiment Construction
[0020] A hydraulically controlled one-way valve, comprising a valve body 1, a valve core 2, a base 3, a spring 4 and a valve sleeve 5, one end of the valve core is fixed on the base, and the other end of the valve core is movable through the valve sleeve, And the valve core can just move along its axis relative to the valve sleeve; the spring is arranged between the base and the valve sleeve; a first blind hole 101 is provided on one side of the valve body, and one end of the base and the valve sleeve can be accommodated in the first blind hole. In the hole, the outer surface of one end of the valve sleeve is sealed and fixed with the valve body, the outer surface of the base is just sealed with the inner surface of the first blind hole, and the base can just move relative to the valve body along the axis of the valve body between the valve sleeve and the valve body; The side of the base away from the valve core is incomplete contact with the bottom surface of the first blind h...

The invention discloses a hydraulic control check valve which comprises a valve body, a valve core, a pedestal, a spring and a valve sleeve; one end of the valve core is fixedly arranged on the pedestal, and the other end of the valve core is movably sleeved in the valve sleeve and is capable of moving relatively to the valve sleeve along an axial line of the valve sleeve; the spring is arranged between the pedestal and the valve sleeve; a first blind hole is arranged on a side face of the valve body; one end of the pedestal and one end of the valve sleeve are just accommodated in the first blind hole; an outer side face of one end of the valve sleeve is fixedly connected with the valve body in a sealing manner; an outer side face of the pedestal is just sealed with an inner side face of the first blind hole and is capable of moving between the valve sleeve and the valve body; a side face of the pedestal away from the valve core is incompletely free from contact with a bottom surface of the first blind hole and forms a gap; an oil inlet of an external control leakage oil path on the valve body is communicated with the gap; an oil inlet and an oil outlet of a control oil path are arranged in one end of the valve sleeve away from the valve body; and the motion of the valve core along an axial line of the valve core can just control the communication between the oil inlet and the oil outlet of the control oil path. The hydraulic control check valve is not only simply and rationally structured, but is capable of achieving a large flow, being a hydraulic control check valve with a large through diameter.
Description
technical field [0001] The invention relates to a hydraulic control one-way valve. Background technique [0002] The check valve is the most common control element in the hydraulic field, but it can only control in one direction. The hydraulically controlled one-way valve relies on controlling the liquid pressure and can realize control in two directions, but the current hydraulically controlled one-way valve only has a small diameter and a small flow rate. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a hydraulically controlled one-way valve, which not only has a simple structure, but also can realize large flow. [0004] The technical solution adopted by the present invention to solve the technical problem is: a hydraulically controlled one-way valve, including a valve body, a valve core, a base, a spring and a valve sleeve, one end of the valve core is fixed on the base, and the The other end of the...
