[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-4 This utility model provides an oil valve testing device, including a water tank 1. Telescopic rods 2 are bolted to the four corners of the bottom inner wall of the water tank 1. A slide 3 is bolted to the top of each telescopic rod 2. The slide 3 has two symmetrically sliding plates 4, with two plates in each plate. A clamping assembly 6 for fixing the workpiece is provided between the two plates in each plate. A bracket 8 is bolted to one side of the water tank 1. A small air pump 9 is bolted to the upper surface of the bracket 8. One end of the small air pump 9 has a connecting hose 10, and the other end of the connecting hose 10 passes through the inner wall of one side of the water tank 1 and connects to one end of one of the clamping assemblies 6. The slide 3 and clamping assembly 6 allow for clamping and fixing of the two ends of the valve workpiece when air tightness testing is required. Gas is then pumped into the workpiece by the small air pump 9, and the air tightness of the valve workpiece is observed by checking for leaks. This eliminates the need for manual testing, reducing labor costs and increasing testing accuracy.

[0022] In this utility model, the clamping assembly 6 includes a connecting pipe 13 that is fixedly connected between two sets of sliding plates 4 by bolts, and the adjacent ends of the two connecting pipes 13 are in close contact with the two ports of the workpiece. One end of the connecting pipe 13 is fixedly connected to a connecting plate 16 by bolts. One end of the connecting pipe 13 is provided with an annular protrusion 14 with the same inner diameter as the port of the workpiece. A sealing ring 15 is fitted on the outer circumference of the annular protrusion 14. Two symmetrical fixing blocks 17 are fixedly connected to the outer circumference of the connecting pipe 13 by bolts. One side of each of the two fixing blocks 17 is fixedly connected to a positioning rod 18 by bolts, and one end of the positioning rod 18 is inserted into the circular hole of the flange on the workpiece. With the clamping assembly 6 and the annular protrusion 14 and sealing ring 15 provided thereon, the sealing effect between the connecting pipe 13 and the valve workpiece can be increased when clamping the valve workpiece, reducing the error caused by external factors and further increasing the accuracy of the detection.

[0023] To facilitate the placement of workpieces into the water tank 1, the lifting assembly 7 includes a U-shaped plate 19 bolted to the water tank 1. Multiple electric push rods 12 are bolted to the upper surface of the U-shaped plate 19. The bottom ends of the electric push rods 12 pass through the top inner wall of the U-shaped plate 19 and are bolted to a connecting frame 11. The bottom end of the connecting frame 11 is fixed to the upper surface of the slide 3. With the lifting assembly 7, when a workpiece needs to be placed into the water tank 1, the multiple electric push rods 12 are extended, causing the workpiece to descend and immerse itself in the water tank 1. The airtightness of the workpiece can be more accurately assessed by observing whether there are air bubbles in the water tank 1.

[0024] To facilitate the clamping and fixing of workpieces, a bidirectional lead screw 5 is rotatably connected between the inner walls of both sides of the slide 3 via bearings. The bidirectional lead screw 5 passes through the two slide plates 4 and is threadedly connected to them. The two ends of the bidirectional lead screw 5 pass through the outer walls of the two slide plates 4 respectively and are fixed to turntables by bolts. The bidirectional lead screw 5 facilitates the movement of the two sets of slide plates 4, thereby facilitating the clamping assembly 6 to clamp and fix the workpiece, making it convenient for operators to operate. A drain pipe is provided on one side of the pool 1 near the bottom, and a water inlet pipe is provided on one side of the pool 1 near the top.

[0025] The use of this utility model involves the following steps:

[0026] S1: When it is necessary to test the air tightness of the valve workpiece, first place the workpiece between the two clamping components 6, then rotate the bidirectional screw 5 to make the two sets of slide plates 4 move closer to each other, so that the two connecting pipes 13 clamp and fix the two ends of the pipe fitting, and seal them between them through the provided sealing ring 15.

[0027] S2: After the workpiece is clamped and fixed, the multi-section electric push rod 12 is extended by starting, thereby driving the connecting frame 11 to move downward and pushing the slide 3 to move downward. When the slide 3 moves downward, it will drive the workpiece on it to move downward until it is immersed in the water tank 1.

[0028] S3: After the workpiece is immersed in the water tank 1, the small air pump 9 is started and gas is delivered into the workpiece through the connecting hose 10. Then, by observing whether bubbles are generated in the water tank 1, the airtightness of the workpiece can be observed more directly.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
