Detailed Description

The embodiment of the hydraulic station as shown in fig. 1 includes an integration valve block 1 and a set of hydraulic pumps 2 (two hydraulic pumps in this embodiment, the number of the hydraulic pumps can be increased according to actual needs), the integration valve block 1 and the set of hydraulic pumps 2 are communicated through a multi-way pipe 3 (three-way pipes are used here corresponding to the number of the hydraulic pumps), and each hydraulic pump 2 can convey hydraulic oil into the integration valve block 1 through the multi-way pipe 3. Taking fig. 1 as an example, in use, one hydraulic pump 2 works, the other hydraulic pump 2 is in a static standby state, the standby hydraulic pump 2 is started when the working hydraulic pump needs to be overhauled, and then the hydraulic pump 2 needing to be overhauled is overhauled, so that the hydraulic station can realize uninterrupted work, in order to avoid the working hydraulic pump 2 inputting hydraulic oil into the static hydraulic pump 2, an oil outlet of each hydraulic pump 2 is provided with a mounting block 4 for mounting a one-way valve, and therefore pressure loss caused by the fact that the hydraulic oil flows into the static hydraulic pump is avoided.

The installation block 4 can realize installing the check valve (plate check valve, cartridge formula check valve, tubular check valve) of different forms, consequently has the commonality, conveniently draws materials on the spot and installs. As shown in figure 2, the mounting block 4 comprises a fixed block 4-1 and a transition block 4-2, the transition block 4-2 is mounted on the transition block 4-2 through bolts, the transition block 4-2 can be dismounted as required, the mounting block 4 is fixedly mounted on a flange of an oil outlet of the hydraulic pump 2, the mounting block 4 is provided with an oil inlet 4-11 and an oil outlet 4-12, the oil inlet 4-11 is opposite to the oil outlet of the hydraulic pump 2, the oil outlet 4-12 is not communicated with the oil inlet 4-11, the transition block 4-2 is provided with a transition hole 4-21, the transition hole 4-21 can communicate the oil outlet 4-12 with the oil inlet 4-11, the transition block 4-2 is also provided with a mounting hole 4-22, the mounting hole 4-22 is communicated with the transition hole 4-21 and is coaxial with one section of the transition hole 4-21, and the axial line of the section of the transition hole 4-21 adjacent to the coaxial transition hole 4-21 is intersected, for example, the transition hole 4-21 is shaped like a v 21274in the structure shown in figure 2, and the two ends of the transition hole 4-21 are vertically and centrally parallel, so that the mounting hole 4-22 can be coaxial with the section of the vertical transition hole 4-21 butted with the oil inlet hole 4-11, or coaxial with the horizontally arranged transition hole 4-21 and close to the side of the section of the vertical transition hole 4-21 butted with the oil outlet hole 4-12.

As shown in fig. 3, a plate-type check valve 5 is mounted on a mounting block 4, the transition block 4-2 needs to be detached when the plate-type check valve 5 is mounted, the plate-type check valve 5 is mounted at a position where the transition block 4-2 is originally mounted, an oil inlet 4-11 and an oil outlet 4-12 are communicated through the plate-type check valve 5, a multi-way pipe 3 is connected to the oil outlet 4-12, hydraulic oil is delivered to the multi-way pipe 3 through the plate-type check valve 5, and the hydraulic oil in the multi-way pipe 3 cannot flow back into the hydraulic pump 2 through the plate-type check valve 5.

As shown in FIG. 4, the cartridge type check valve 6 is installed on the installation block 4, and the cartridge type check valve 6 is installed in the installation hole 4-22 of the transition block 4-2, so that the transition block 4-2 and the cartridge type check valve 6 form a mechanism similar to the plate type check valve 5. In this example, the multi-way pipe 3 is connected to the oil outlet 4-12, the hydraulic oil is delivered to the multi-way pipe 3 through the transition block 4-2 and the cartridge type check valve 6, and the hydraulic oil in the multi-way pipe 3 cannot flow back into the hydraulic pump 2 from the transition block 4-2 through the cartridge type check valve 6.
