[0033] The technical solution of the utility model adopts a valve pressure testing device 1000 including a bearing seat 10, a first docking structure 20, a second docking structure 30 and a fluid circuit system 40. When performing a pressure test on a regulating valve, the regulating valve to be tested is placed on the bearing seat 10, and is connected to the fluid circuit system 40 via a first pair of joints 44 and a second pair of joints 47; and the first docking structure 20 and the second docking structure 30 have a first movable portion 21 and a second movable portion 31 movably arranged in the transverse direction, and the distance between the first pair of joints 44 and the second pair of joints 47 can be adjusted so that the fluid circuit system 40 can be connected to valves of various specifications, and pressure tests can be performed on valves of various specifications.

[0034] At the same time, the first pressure-bearing pipe 43 and the second pressure-bearing pipe 46 are used as intermediate media for moving the first pair of joints 44 and the second pair of joints 47. The outside of the first pressure-bearing pipe 43 is connected to the first movable part 21, and the inside of the first pressure-bearing pipe 43 is connected to the liquid circuit system 40, so that the first pair of joints 44 can move under the drive of the first movable part 21; the outside of the second pressure-bearing pipe 46 is connected to the second movable part 31, and the inside of the second pressure-bearing pipe 46 is connected to the liquid circuit system 40, so that the second pair of joints 47 can move under the drive of the second movable part 31.

[0035] In order to support and place the regulating valve, a circular platform, a rectangular platform or a bracket structure may be provided to form a bearing area 11. Optionally, a groove corresponding to the shape of the regulating valve may be further provided on the bearing area 11 to facilitate placement and installation.

[0036] In the selection of the first docking structure 20 and the second docking structure 30, the first docking structure 20 and the second docking structure 30 can be selected as two hydraulic cylinders whose movement directions are on an axis and are arranged opposite to each other, and the movable ends of the two hydraulic cylinders are respectively the first movable part 21 and the second movable part 31. The first docking structure 20 and the second docking structure 30 can also be selected as two motors, gears, and the first movable part 21 and the second movable part 31 with racks that are respectively arranged. When the control valve to be detected is connected with the first pair of joints 44 and the second pair of joints 47, the first movable part 21 drives the first pair of joints 44 to move horizontally, and the second movable part 31 drives the second pair of joints 47 to move horizontally, so as to control the distance between the two joints to adapt to valves of different lengths, thereby connecting the control valve to be detected with the fluid path system 40.

[0037] See also Figure 1 In one embodiment of the utility model, in order to adapt to different heights of the regulating valve body, the bearing seat 10 can be movably arranged up and down.

[0038] The technical solution of the utility model uses a supporting seat 10 to support the regulating valve to be tested, and the supporting seat 10 is movably arranged up and down to control the height of the water inlet end and the water outlet end of the regulating valve to be tested, so as to facilitate the communication between the regulating valve to be tested and the liquid circuit system 40 through the first pair of joints 44 and the second pair of joints 47.

[0039] In order to realize the lifting and lowering of the bearing seat 10, a hydraulic cylinder is arranged below the bearing area 11. The movement direction of the hydraulic cylinder is the same as the lifting and lowering direction of the bearing seat 10. The movable end of the hydraulic cylinder is fixedly connected to the lower part of the bearing area 11 through a connecting structure. Optionally, the lifting and lowering of the bearing seat 10 can also be controlled by a motor and a pulley block. Before installing the regulating valve to be tested, the hydraulic cylinder or the motor is controlled to drive the bearing seat 10 to rise and fall to a suitable height. When placing the valve to be tested, the two ends of the regulating valve to be tested can be kept at the same height as the first pair of joints 44 and the second pair of joints 47, respectively, and then the first pair of joints 44 and the second pair of joints 47 are used to connect the two ends of the valve to be tested.

The first clamping structure 50 and the second clamping structure 60 correspondingly have clamping parts that are movably arranged in the longitudinal direction.

[0041] The technical solution of the utility model uses the longitudinally movable first clamping structure 50 and the second clamping structure 60 to maintain the stability of the control valve to be tested when it is placed on the bearing seat 10, thereby preventing the control valve to be tested from tipping over.

[0042] Among them, in order to fix the regulating valve to be tested, the first clamping structure 50 and the second clamping structure 60 are two hydraulic cylinders whose movement directions are on an axis and are relatively arranged. The movable ends of the two hydraulic cylinders are respectively the first clamping part 51 and the second clamping part 61. After the valve to be tested is placed on the bearing seat 10 or connected to the hydraulic system 40, the movable ends of the hydraulic cylinders move toward the regulating valve to be tested to clamp and fix the regulating valve to be tested. Optionally, two clamping plates can also be installed on the bearing seat 10 to clamp the regulating valve to be tested, thereby enhancing the placement stability of the regulating valve to be tested and reducing safety hazards.

[0043] See also Figure 3 In one embodiment of the utility model, the first pair of joints 44 and the second pair of joints 47 can move under the drive of the first movable part 21 and the second movable part 31.

[0044] The technical solution of the present utility model uses the first movable tube 422 and the third movable tube 423 to movably set the first pair of joints 44 relative to the first liquid circuit 42, and uses the second movable tube 452 and the fourth movable tube 453 to movably set the second pair of joints 47 relative to the second liquid circuit 45, thereby facilitating the adjustment of the distance between the first pair of joints 44 and the second pair of joints 47.
