Description

Technical Field

[0001] This utility model belongs to the field of ball valve sealing testing technology, and in particular relates to a testing device for high-performance ball valve sealing. Background Technology

[0002] One testing device for high-performance ball valve seals is a ball valve sealing performance test bench. This device can fill the ball valve with a certain pressure of gas, such as air or nitrogen, and evaluate its airtightness by observing the pressure change of the valve over a period of time or by using wet leak detection, dry leak detection, or other methods.

[0003] Existing ball valve sealing testing devices lack a positioning mechanism, which can easily lead to improper positioning or angle when inserted into the ball valve for testing. This can cause scratching and wear on the ball valve sealing surface, affecting not only the sealing performance and service life, but also causing deviations in the test results. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for high-performance ball valve seals. By setting a fixing mechanism, it solves the problem that improper position or angle can easily occur when inserting the ball valve for testing, causing scratching and wear on the ball valve sealing surface. This not only affects the sealing performance and service life, but also causes deviations in the test results.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a testing device for high-performance ball valve seals, including a testing platform, on which a fixing mechanism and a testing mechanism are provided;

[0007] The fixing mechanism includes two tracks fixedly connected to the bottom of the testing platform, two sliding plates slidably connected to the outer surfaces of the two tracks, a hydraulic push rod fixedly connected to the bottom of the testing platform, the output end of the hydraulic push rod fixedly connected to the corresponding sliding plate, a main connecting rod rotatably connected to the bottom of the testing platform, two side connecting rods hinged to the bottom of the main connecting rod, the ends of the two side connecting rods away from the main connecting rod being hinged to the two sliding plates, two sliding grooves opened on the top of the testing platform, and clamps fixedly connected to the top of the two sliding plates.

[0008] Furthermore, the top ends of both clamps extend outside the two slide grooves and are slidably connected to the two slide grooves. The detection mechanism includes a bottom sealing cover fixedly connected to the top of the detection table. A ball valve is provided on the outer wall of the bottom sealing cover, and both clamps are in contact with the ball valve.

[0009] Furthermore, two slide rods are fixedly connected to the top of the testing platform, and a top plate is fixedly connected to the top of the two slide rods. A hydraulic push rod II is sleeved on the top plate, and an air inlet pipe is fixedly connected to the output end of the hydraulic push rod II.

[0010] Furthermore, the bottom end of the intake pipe extends into the ball valve, the intake pipe is connected to the ball valve, and an air supply pipe is fixedly connected to the outer wall of the intake pipe, the air supply pipe being connected to the intake pipe.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a fixing mechanism, when testing a ball valve, first insert the bottom interface of the ball valve into the bottom sealing cover on the testing platform. Then, start the hydraulic push rod one. The hydraulic push rod one will push the corresponding slide plate inward. Since the corresponding slide plate is connected to the side connecting rod, and the side connecting rod is connected to the main connecting rod, through the transmission of the main connecting rod, it can use another side connecting rod to make the other slide plate and the previous slide plate move their respective clamps closer to each other in sync, thereby positioning and fixing the ball valve on the bottom sealing cover. This can prevent the ball valve from shifting when it is inserted into the testing device, and avoid scratching of the ball valve sealing surface, which would affect the testing effect.

[0013] 2. After positioning by setting up the detection mechanism, the second hydraulic push rod can be activated. The second hydraulic push rod will push the air inlet pipe and the upper end face of the ball valve to fit tightly under the action of extrusion force. At the same time, under this pressure, the lower end of the ball valve will also be squeezed against the bottom sealing cover, thereby forming a sealed space. Then, air is injected through the air supply pipe interface on the side of the air inlet pipe. At this time, the operator needs to observe the pressure value at the terminal. If the pressure value drops, it means that the ball valve is not sealing properly. If the pressure value remains unchanged, it means that the ball valve is qualified.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 As shown, this utility model is a testing device for high-performance ball valve seals, including a testing platform 1, on which a fixing mechanism 2 and a testing mechanism 3 are provided;

[0025] The fixing mechanism 2 includes two rails 21 fixedly connected to the bottom of the testing table 1. Two slide plates 22 are slidably connected to the outer surfaces of the two rails 21. A hydraulic push rod 23 is fixedly connected to the bottom of the testing table 1. The output end of the hydraulic push rod 23 is fixedly connected to the corresponding slide plate 22. A main connecting rod 24 is rotatably connected to the bottom of the testing table 1. Two side connecting rods 25 are hinged to the bottom of the main connecting rod 24. The ends of the two side connecting rods 25 away from the main connecting rod 24 are hinged to the two slide plates 22. Two sliding grooves 26 are opened on the top of the testing table 1. Clamps 27 are fixedly connected to the top of the two slide plates 22. The top ends of the two clamps 27 extend outside the two sliding grooves 26 and are slidably connected to the two sliding grooves 26.

[0026] By setting the fixing mechanism 2, when testing the ball valve 32, the bottom interface of the ball valve 32 is first inserted into the bottom sealing cover 31 on the testing table 1. Then, the hydraulic push rod 23 is activated, which pushes the corresponding slide plate 22 to move inward. Since the corresponding slide plate 22 is connected to the side connecting rod 25, and the side connecting rod 25 is connected to the main connecting rod 24, through the transmission of the main connecting rod 24, it can use another side connecting rod 25 to make the other slide plate 22 and the previous slide plate 22 move their respective clamps 27 closer to each other, thereby positioning and fixing the ball valve 32 on the bottom sealing cover 31. This can prevent the ball valve from shifting when it is inserted into the testing device, avoid scratching of the ball valve sealing surface, and avoid affecting the testing effect.

[0027] The testing mechanism 3 includes a bottom sealing cover 31 fixedly connected to the top and bottom of the testing platform 1. A ball valve 32 is provided on the outer wall of the bottom sealing cover 31. Two clamps 27 are in contact with the ball valve 32. Two slide rods 33 are fixedly connected to the top of the testing platform 1. A top plate 34 is fixedly connected to the top of the two slide rods 33. A hydraulic push rod 35 is sleeved on the top plate 34. An air inlet pipe 36 is fixedly connected to the output end of the hydraulic push rod 35. The bottom end of the air inlet pipe 36 extends into the ball valve 32. The air inlet pipe 36 communicates with the ball valve 32. An air supply pipe 37 is fixedly connected to the outer wall of the air inlet pipe 36. The air supply pipe 37 communicates with the air inlet pipe 36.

[0028] After positioning by setting up the detection mechanism 3, the hydraulic push rod 35 can be activated. The hydraulic push rod 35 will push the air inlet pipe 36 to fit tightly against the upper end face of the ball valve 32 under the action of extrusion force. At the same time, under this pressure, the lower end of the ball valve 32 will also be squeezed against the bottom sealing cover 31, thereby forming a sealed space. Then, air is injected through the air supply pipe 37 interface on the side of the air inlet pipe 36. At this time, the operator needs to observe the pressure value at the terminal. If the pressure value drops, it means that the sealing of the ball valve 32 is unqualified. If the pressure value remains unchanged, it means that the ball valve 32 is qualified.

[0029] A specific application of this embodiment is as follows: When testing the ball valve 32, firstly, the bottom interface of the ball valve 32 is inserted into the bottom sealing cover 31 on the testing platform 1. Then, the hydraulic push rod 23 is activated, which pushes the corresponding slide plate 22 inward. Since the corresponding slide plate 22 is connected to the side connecting rod 25, and the side connecting rod 25 is connected to the main connecting rod 24, through the transmission of the main connecting rod 24, it can, with the help of another side connecting rod 25, make the other slide plate 22 and the previous slide plate 22 synchronously drive their respective clamps 27 to move closer to each other, thereby positioning and fixing the ball valve 32 on the bottom sealing cover 31. This prevents the ball valve from being inserted into the testing platform. During the testing process, displacement occurs to prevent scratching of the ball valve sealing surface, which would affect the testing results. After positioning, hydraulic push rod 35 can be activated. Hydraulic push rod 35 will push the air inlet pipe 36 to tightly fit the upper end face of the ball valve 32 under the action of extrusion force. At the same time, under this pressure, the lower end of the ball valve 32 will also be squeezed against the bottom sealing cover 31, thereby forming a sealed space. Then, air is injected through the air supply pipe 37 interface on the side of the air inlet pipe 36. At this time, the operator needs to observe the pressure value at the terminal. If the pressure value drops, it means that the sealing performance of the ball valve 32 is unqualified. If the pressure value remains unchanged, it means that the ball valve 32 is qualified.
