Description

Technical Field

[0001] This utility model relates to the field of test bench technology, and in particular to a priority valve test bench. Background Technology

[0002] The priority valve has multiple ports, such as the oil inlet, priority port, bypass port, and return port. During testing, the operator needs to identify the corresponding port and connect the corresponding testing equipment to the corresponding port through the test tube. In this process, the port identification may be incorrect, and the process of identifying the port also reduces the testing efficiency. Utility Model Content

[0003] This invention proposes a priority valve testing bench, which uses a positioning groove to position the valve port of the priority valve, and a telescopic cylinder to drive a quick connector to be directly inserted into the corresponding valve port, thereby improving testing efficiency.

[0004] The technical solution of this utility model is implemented as follows: a priority valve test bench includes a workbench with a positioning groove on the workbench. The opening of the positioning groove faces upward and the shape of the positioning groove matches that of the priority valve. A horizontally sliding quick connector is provided on the workbench. The quick connector is connected to a telescopic cylinder. The position of the quick connector corresponds one-to-one with the valve port of the priority valve. The end of the quick connector away from the valve port is connected to the test tube.

[0005] Furthermore, the workbench is equipped with slide grooves that correspond one-to-one with the quick-connect couplings, and the quick-connect couplings move along the slide grooves.

[0006] Furthermore, the quick-connect fitting includes a hollow housing, with one end of the housing near the valve port being tapered and the other end being provided with a limiting platform. A sealing ring is provided on the side of the limiting platform near the tapered end.

[0007] Furthermore, a clamping mechanism is also provided on the worktable to fix the priority valve in the positioning groove.

[0008] Furthermore, the clamping mechanism includes a vertically lifting lower pressure plate, which is located above the positioning groove.

[0009] Furthermore, the lower pressure plate is connected to a vertically telescopic hydraulic cylinder.

[0010] The beneficial effects of this utility model are: This invention uses positioning grooves to position each valve port of the priority valve. Simply place the priority valve into the positioning groove to complete the positioning and identification of each valve port. Then, the telescopic cylinders are activated to insert the quick connectors into the corresponding valve ports in one go. The operation is simple and convenient, and there is no need for inspection personnel to identify the valve ports, thus improving inspection efficiency. Attached Figure Description

[0011] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below.

[0013] Workbench 1, positioning groove 2, priority valve 3, quick connector 4, slide 5, test tube 6, telescopic cylinder 7, outer shell 8, limit platform 9, sealing ring 10, lower pressure plate 11, hydraulic cylinder 12. Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 like Figure 1-2 As shown, a priority valve test bench includes a workbench 1 with a positioning groove 2 on the workbench 1. The opening of the positioning groove 2 faces upward and the shape of the priority valve 3 matches the inside of the positioning groove 2. When the priority valve 3 is placed in the positioning groove 2 in a uniform and fixed position, the position of each valve port of the priority valve 3 is fixed.

[0016] The workbench 1 is equipped with quick-connect couplings 4, each corresponding to a valve port of the priority valve 3. The workbench 1 also has corresponding grooves 5 for each quick-connect coupling 4. The quick-connect coupling 4 moves along the grooves 5, which limit its movement path to ensure smooth insertion into the corresponding valve port. The position of the quick-connect coupling 4 is determined based on the position of the priority valve 3's valve port.

[0017] The end of quick-connector 4 furthest from the valve port is connected to the test tube, which is connected to the matching testing equipment, which is existing technology. Quick-connector 4 is connected to telescopic cylinder 7, which is fixed on the worktable 1. The telescopic cylinder 7 drives quick-connector 4 to reciprocate horizontally.

[0018] The quick-connector 4 includes a hollow housing 8. One end of the housing 8 near the valve port is a conical end, and the other end is provided with a limiting platform 9. The limiting platform 9 and the housing 8 are an integral structure. A sealing ring 10 is fixed on the side of the limiting platform 9 near the conical end.

[0019] Place the priority valve 3 in the positioning groove 2, and then start the telescopic cylinder 7. The telescopic cylinder 7 drives the quick connector 4 to be inserted into the corresponding valve port, and the sealing ring 10 plays a sealing role. After the test is completed, the telescopic cylinder 7 retracts, driving the quick connector 4 to be pulled out from the valve port.

[0020] Example 2 This embodiment is basically the same as Embodiment 1, except that, as Figure 3 As shown, a clamping mechanism is also provided on the workbench 1, which fixes the priority valve 3 in the positioning groove 2. The clamping mechanism includes a vertically lifting lower pressure plate 11, the lower side of which matches the upper surface of the priority valve 3. The lower pressure plate 11 is located above the positioning groove 2 and is connected to a vertically extending hydraulic cylinder 12. When the priority valve 3 is placed in the positioning groove 2, the hydraulic cylinder 12 extends, causing the lower pressure plate 11 to move downward, fixing the priority valve 3 in the positioning groove 2 and preventing the priority valve 3 from shaking during the test, which would affect the test results.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
