Description

Technical Field

[0001] This utility model relates to a flip-type fluoropolymer-lined ball valve sealing testing device. Background Technology

[0002] After the fluoropolymer-lined ball valve is manufactured, it needs to undergo a sealing test to ensure its quality. Traditionally, this involves manually connecting the ball valve to water for testing and checking for leaks. This method is inefficient, requires repeated valve disassembly, and is both inconvenient and slow. Utility Model Content

[0003] This invention addresses the aforementioned problem by providing a flip-type PTFE-lined ball valve sealing testing device that is convenient and efficient to use.

[0004] This utility model is constructed as follows: it includes a testing pool and a testing frame disposed in the testing pool and capable of being flipped off or immersed in the pool. Two support components are symmetrically arranged on the testing frame for pre-fixing both ends of the workpiece, respectively. Each support component is provided with a telescopic component. An air inflator is provided at the output end of the telescopic component. An air inflator and the support components form a workpiece clamping space. When the air inflator presses the workpiece, the air outlet of the air inflator faces the end of the workpiece and inflates the workpiece.

[0005] Furthermore, the support assembly includes two support hooks arranged symmetrically on the left and right.

[0006] Furthermore, the inflation plate has an annular sealing layer at one end near the workpiece, and a sealing layer through hole in the middle of the annular sealing layer, which corresponds to the air outlet of the inflation plate.

[0007] Furthermore, a chassis is provided next to the testing pool, and the air inlet of the air inflator is connected to an air pump located inside the chassis via an air passage.

[0008] Furthermore, the telescopic component is a cylinder, and the cylinder output end is connected to the inflation plate via a connecting shaft.

[0009] Furthermore, the testing frame includes two screws, and three support plates are arranged on the two screws from top to bottom. One support component and telescopic component are arranged on the support plate located in the middle, and the other support component and telescopic component are located on the support plate at the bottom.

[0010] Furthermore, the support plate has through holes at both ends for threading screws. Nuts are provided above and below the connection between the screws and the through holes of the support plate, and the nuts are threadedly engaged with the screws.

[0011] Furthermore, a flipping block is provided at the bottom of the testing frame, and a rotating shaft is provided in the testing water tank. The rotating shaft passes through the flipping block and is fixed thereto. The rotating shaft is driven by a motor to rotate, so as to flip the testing frame into or out of the testing water tank.

[0012] Furthermore, the two ends of the rotating shaft are connected to the inner wall of the detection pool via bearings.

[0013] Furthermore, the front and rear parts of the testing pool are respectively provided with two front and rear support columns. When the testing frame is flipped out of the testing pool, the lower support plate abuts against the two rear support columns. When the testing frame is flipped into the testing pool, the upper support plate abuts against the two front support columns.

[0014] Compared with the prior art, this utility model has the following advantages: The device has a simple structure, reasonable design, is convenient to use, and saves time and effort. The upper and lower parts of the fluoropolymer-lined ball valve are placed in two workpiece clamping spaces respectively. The telescopic component drives the inflation plate to press the upper and lower parts of the fluoropolymer-lined ball valve for positioning. At the same time, the air outlet of the inflation plate is aligned with the two ports of the fluoropolymer-lined ball valve and sealed through the annular sealing layer. The inflation plate inflates the fluoropolymer-lined ball valve. The motor drives the test frame and the fluoropolymer-lined ball valve to rotate 90 degrees clockwise via the rotating shaft, so that the fluoropolymer-lined ball valve is submerged in the water of the test pool for a period of time. Observe whether there are bubbles in the water. If there are bubbles on the outer surface of the fluoropolymer-lined ball valve, it indicates that the fluoropolymer-lined ball valve has a poor sealing problem. If there are no bubbles on the surface of the fluoropolymer-lined ball valve, it indicates that the fluoropolymer-lined ball valve is qualified for sealing. After the test is completed, the motor drives the test frame and the fluoropolymer-lined ball valve to rotate 90 degrees counterclockwise to reset. The telescopic cylinder retracts and drives the inflation plate to reset. The fluoropolymer-lined ball valve is removed, and the sealing test of the next fluoropolymer-lined ball valve is continued, which greatly improves the testing quality and efficiency.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example: Figures 1-5 As shown in this embodiment, a flip-type fluoropolymer-lined ball valve sealing testing device is provided, including a testing water tank 1 filled with water and a testing frame 2 set in the testing water tank and which can be flipped off or immersed in the water tank. Two support components 3 are symmetrically arranged on the testing frame for pre-fixing the two ends of the workpiece respectively. Each support component is provided with a telescopic component 4. An air inflator 5 is provided at the output end of the telescopic component. A workpiece clamping space 6 is formed between the air inflator 5 and the support component. When the air inflator 5 presses the workpiece, the air outlet of the air inflator 5 faces the port of the workpiece and inflates the workpiece.

[0022] During operation, the upper and lower parts of the fluoropolymer-lined ball valve are placed in the clamping spaces of the two workpieces respectively. The telescopic assembly drives the inflation plate to press the upper and lower parts of the fluoropolymer-lined ball valve for positioning. At the same time, the air outlet of the inflation plate is aligned with the two ports of the fluoropolymer-lined ball valve and sealed through the annular sealing layer. The inflation plate inflates the fluoropolymer-lined ball valve with air. The motor drives the test frame and the fluoropolymer-lined ball valve to rotate 90 degrees clockwise via the rotating shaft, so that the fluoropolymer-lined ball valve is submerged in the test water tank for a period of time. Observe whether bubbles are generated in the water. If bubbles are generated on the outer surface of the fluoropolymer-lined ball valve, it indicates that the fluoropolymer-lined ball valve has a poor sealing problem. If no bubbles are generated on the surface of the fluoropolymer-lined ball valve, it indicates that the fluoropolymer-lined ball valve is sealed properly. After the test is completed, the motor drives the test frame and the fluoropolymer-lined ball valve to rotate 90 degrees counterclockwise to reset. The telescopic cylinder retracts and drives the inflation plate to reset, and the fluoropolymer-lined ball valve is removed.

[0023] It is worth noting that when the PTFE-lined ball valve 10 is submerged in water, the valve should be opened by rotating the valve to ensure it is in a connected state for observation. Then, the valve should be closed for further observation to ensure the sealing quality of the PTFE-lined ball valve. Furthermore, after removing the PTFE-lined ball valve, with the valve switch 11 closed, water can be poured into one port of the valve for observation, and then water can be poured into the other port for further observation to ensure the quality of the PTFE-lined ball valve.

[0024] In this embodiment of the utility model, the support component 3 includes two support hooks 301 arranged symmetrically on the left and right; the minimum distance between the two support hooks is less than the maximum width of the fluoropolymer-lined valve body; the contact surface between the support hooks and the fluoropolymer-lined ball valve can be a plane.

[0025] In this embodiment of the utility model, the inflatable plate 5 is provided with an annular sealing layer 501 at one end near the workpiece, and a sealing layer through hole is provided in the middle of the annular sealing layer, which corresponds to the air outlet of the inflatable plate.

[0026] The diameter of the annular sealing layer is larger than that of the inflation plate. When the telescopic component drives the inflation plate to press against the pipe port of the fluoropolymer-lined ball valve, the annular sealing layer plays a sealing role to prevent air leakage. The annular sealing layer can be a sealing ring of existing technology.

[0027] In this embodiment of the utility model, a housing 7 is provided next to the detection pool, and the inside of the inflation plate is a sealed cavity. An air inlet 502 and an air outlet 503 are connected to the outside of the sealed cavity. The air inlet of the inflation plate is connected to an air pump 8 provided in the housing via an air passage 801, and the inflation plate is inflated by the air pump.

[0028] In this embodiment of the utility model, the telescopic component is a cylinder 401, and the cylinder output end is fixedly connected to the inflation plate via a connecting shaft 402.

[0029] In this embodiment of the utility model, the testing frame 2 includes two screws 201, and three support plates 202 are arranged from top to bottom on the two screws. One support component and telescopic component are arranged on the support plate located in the middle, and the other support component and telescopic component are symmetrically arranged on the support plate at the bottom.

[0030] The three support plates mentioned above have the same connection structure as the two screws. Each support plate has through holes at both ends for threading the screws. After the screws pass through the support plates, nuts 203 are provided above and below the connection between the screws and the through holes of the support plates. The nuts are threadedly engaged with the screws, and the two nuts serve to limit the position of the support plates.

[0031] In this embodiment of the utility model, in order to enable the overall testing frame to rotate 90 degrees clockwise to enter the water in the testing pool, and at the same time, the overall testing frame can rotate 90 degrees counterclockwise to leave the testing pool, a flipping block 204 is provided at the bottom of the testing frame. The flipping block is located behind the cylinder of the lower telescopic component. A rotating shaft 205 is provided in the testing pool. The two ends of the rotating shaft are rotatably engaged with the testing pool. The rotating shaft passes through the flipping block and is fixed thereto. The rotating shaft is driven to rotate by a motor 9 to drive the testing frame to flip into or out of the testing pool. The motor is located in the housing, and the motor output shaft is fixed to the end of the rotating shaft.

[0032] The two ends of the aforementioned rotating shaft are connected to the inner wall of the testing pool via bearings 206.

[0033] In this embodiment of the utility model, in order to ensure the stability of the detection pool after it is flipped over, two front and two rear support columns are respectively provided at the front and rear of the detection pool. When the detection frame flips out of the detection pool, the lower support plate abuts against the two rear support columns 207, which plays an auxiliary support role and enhances stability. When the detection frame flips into the detection pool, the upper support plate abuts against the two front support columns 208, which also plays an auxiliary support role and enhances stability.

[0034] In this embodiment of the utility model, a simple placement platform 209 is provided on the rear part of the upper surface of the support plate located below.
