Embodiment Construction

[0018] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] A specific embodiment of the integrated hydraulic control check valve of the present invention, such as figure 1 shown. The integrated hydraulic control check valve 5 includes a valve body 51, on which a first oil passage is arranged, and a first check valve spool 55 is arranged in series in the first oil passage to separate the first oil passage into a second oil passage. Section 53 and the first oil section 57, the valve body 51 is also provided with a rodless cavity oil passage arranged in an L shape with the second oil section, and the first check valve spool 55 is provided with a It is connected to the first check valve spool passage of the second oil section 53 and the oil passage of the rodless chamber. Similarly, a second oil passage is provided on the valve body 51, and a second check valve spool 56 is arranged in series in the second o...

Abstract

The invention relates to an integrated type hydraulic control check valve. Through the integrated type hydraulic control check valve, the problem that in the prior art, a check valve cannot meet the usage requirement of a compact-structure type hydraulic transmission system is solved. In order to achieve the purpose, the integrated type hydraulic control check valve adopts the mode that respective control over two valve cores (namely two oil channels) of the check valve is achieved through different-direction movements of a piston. Compared with the mode that two oil channels are controlled by two pistons respectively, the space size of the integrated type hydraulic control check valve is decreased effectively, thus the concrete structure of the integrated type hydraulic control check valve is more compact, and the usage requirements of some high-integration-level compact-structure hydraulic transmission systems can be met. In the usage process, hydraulic oil pushes the piston to move upwards, in this way, the first valve core of the check valve can be opened, and the first oil channel is opened. The hydraulic oil pushes the piston to move downwards, in this way, the second valve core of the check valve can be opened, and the second oil channel is opened.

Description

technical field [0001] The invention relates to an integrated hydraulic control check valve. Background technique [0002] In some hydraulic transmission systems, since the effective area of ​​the rod chamber and the rodless chamber are different, it is necessary to replenish oil to the rod chamber of the hydraulic cylinder and discharge oil to the rodless chamber of the hydraulic cylinder through the oil tank, such as the Chinese patent 200710018110.0 discloses a new pump-controlled hydraulic transmission system directly servo-driven by a switched reluctance motor, including a hydraulic cylinder, a plunger pump with an oil outlet connected to both ends of the hydraulic cylinder through a pipeline, and an oil tank for sucking and discharging oil from the plunger pump, and the hydraulic cylinder The rod chamber of the hydraulic cylinder is connected to the fuel tank through the oil supply circuit composed of pipelines, and the rodless chamber of the hydraulic cylinder is conn...
