Description

Technical Field

[0001] This utility model relates to a lifting-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 lifting-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 water tank and a lifting plate that is installed inside the testing water tank and can move up and down. A limiting component for placing a fluoropolymer-lined ball valve is provided in the middle of the lifting plate. Inflating discs are symmetrically arranged on both sides of the limiting component. The inflating discs can move synchronously relative to each other or in opposite directions along the length of the lifting plate. When the two inflating discs synchronously press the two ports of the fluoropolymer-lined ball valve inward, the air outlet of the inflating disc is facing the port of the workpiece and inflates the workpiece.

[0005] Furthermore, the limiting component includes two spaced-apart support plates, with limiting grooves symmetrically provided on the upper part of the two support plates.

[0006] Furthermore, the limiting groove is arc-shaped.

[0007] Furthermore, the lifting plate is provided with support plate fixing blocks at the front and rear, and the support plate fixing blocks are connected to the front and rear of the support plate.

[0008] 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.

[0009] Furthermore, a chassis is provided behind 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.

[0010] Furthermore, the inflatable disc is moved by a drive assembly.

[0011] Furthermore, the drive assembly includes a cylinder, and cylinder mounting plates are provided on both sides of the cylinder, with the cylinder fixed between the two cylinder mounting plates.

[0012] Furthermore, the lifting plate is driven to move up and down by a lifting assembly.

[0013] Furthermore, the lifting assembly includes a guide rail and a connecting bracket disposed in front of the guide rail. A slide block is disposed between the guide rail and the connecting bracket. The rear of the slide block is slidably engaged with the guide rail, the front of the slide block is fixed to the rear of the connecting bracket, and the front of the connecting bracket is fixed to the lifting plate. The slide block is driven by a lifting cylinder to move along the guide rail, and the output end of the lifting cylinder is connected to the slide block via a pusher.

[0014] Compared with the prior art, this utility model has the following advantages: The device has a simple structure, reasonable design, is easy to use, and saves time and effort. By placing the fluoropolymer-lined ball valve in the limiting groove of the two support plates of the limiting component for limiting, the two cylinders drive the inflation plates on both sides to clamp the fluoropolymer-lined ball valve. 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 pump is started, and air is pumped into the fluoropolymer-lined ball valve through the air passage and inflation plate. The lifting component drives the lifting plate to move downward, so that the fluoropolymer-lined ball valve is submerged in the water in 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 sealed properly. After the test is completed, the lifting component drives the lifting plate to move upward and reset, the two cylinders retract and reset, and the tested fluoropolymer-lined ball valve is taken out to continue the test of the next fluoropolymer-lined ball valve, which greatly improves the test quality and efficiency.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example: Figures 1-4As shown in this embodiment, a lifting-type fluoropolymer-lined ball valve sealing testing device is provided, including a testing water tank 1 filled with water and a lifting plate 2 installed inside the testing water tank and movable up and down. A limiting component 3 for placing the fluoropolymer-lined ball valve is provided in the middle of the lifting plate. Inflating discs 4 are symmetrically arranged on both sides of the limiting component. The inflating discs can move synchronously relative to each other or in opposite directions along the length of the lifting plate. When the two inflating discs synchronously press the two ports of the fluoropolymer-lined ball valve inward, the air outlet of the inflating disc faces the port of the workpiece and inflates the workpiece.

[0021] During operation, the fluoropolymer-lined ball valve is placed in the limiting grooves of the two support plates of the limiting assembly for limiting. Two cylinders drive the inflation plates on both sides to clamp the fluoropolymer-lined ball valve. At the same time, the air outlets of the inflation plates are aligned with the two ports of the fluoropolymer-lined ball valve and sealed through the annular sealing layer. The inflation pump is started, and air is pumped into the fluoropolymer-lined ball valve through the air passage and inflation plates. The lifting assembly drives the lifting plate to move downward, so that the fluoropolymer-lined ball valve is submerged in the water in the test pool 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 successfully. After the test is completed, the lifting assembly drives the lifting plate to move upward and reset, the two cylinders retract and reset, and the tested fluoropolymer-lined ball valve is taken out to continue the test of the next fluoropolymer-lined ball valve.

[0022] It is worth noting that when the PTFE-lined ball valve is submerged in water, the valve should be opened by rotating the valve switch to ensure it is in a connected state for observation. Then, the valve switch 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 valve switch 81 in the closed state, water can be poured into one port of the PTFE-lined ball valve for observation, and then water can be poured into the other port for observation to check for air bubbles, thus ensuring the internal sealing quality of the PTFE-lined ball valve.

[0023] In this embodiment of the utility model, the limiting component 3 includes two spaced support plates 31, with a space between the two support plates for accommodating the middle part of the fluoropolymer-lined ball valve. The upper part of the two support plates is symmetrically provided with limiting grooves 32. The limiting grooves are arc-shaped to adapt to the shape of the fluoropolymer-lined ball valve.

[0024] In this embodiment of the utility model, a support plate fixing block 33 is provided at the front and rear of the lifting plate, and the support plate fixing block is connected to the front and rear of the support plate.

[0025] The aforementioned support plate fixing block has a slot on its inner side. The front and rear of the support plate are inserted into the slot to fix the support plate. It can also be used to replace the limiting groove with different curvatures to adapt to different models of PTFE-lined ball valves.

[0026] In this embodiment of the utility model, an annular sealing layer 41 is provided at one end of the inflation plate 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 inflation plate.

[0027] 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.

[0028] In this embodiment of the present invention, a fixing sleeve 44 is provided between the inflation plate and the output shaft of the cylinder, and the two sides of the fixing sleeve are respectively fixed to the inflation plate and the output shaft of the cylinder.

[0029] In this embodiment of the utility model, a housing 5 is provided behind the detection pool, and the air inlet of the inflation plate is connected to the inflation pump 43 located in the housing via the air passage 42. The inside of the inflation plate is a sealed cavity, and an air inlet and an air outlet are provided outside the sealed cavity. The air pump inflates the inflation plate through the air passage and the air inlet, and then outputs the air to the inside of the fluoropolymer-lined ball valve through the air outlet.

[0030] In this embodiment of the invention, the inflatable disc is moved by the drive assembly 6.

[0031] The drive assembly includes a cylinder 61, and cylinder mounting plates 62 are provided on both sides of the cylinder, with the cylinder fixed between the two cylinder mounting plates.

[0032] In this embodiment of the invention, the lifting plate is driven to move up and down by the lifting assembly 7.

[0033] The lifting assembly includes a guide rail 71 disposed on the front of the chassis and a connecting bracket 72 disposed in front of the guide rail. A slide block 73 is disposed between the guide rail and the connecting bracket. The rear of the slide block is slidably engaged with the guide rail, and the front of the slide block is fixed to the rear of the connecting bracket. The front of the connecting bracket is fixed to the lifting plate. The slide block is driven by a lifting cylinder 74 to move along the guide rail. The output end of the lifting cylinder is connected to the slide block via a pusher 75. The pusher can be in the shape of a bend or an L. One end of the pusher is fixed to the slide block, and the other end is connected to the output shaft of the lifting cylinder. Of course, the lifting cylinder here can also be replaced by a hydraulic cylinder or the like to achieve the lifting function.

[0034] In this embodiment of the utility model, a clearance groove 51 is provided on the lower part of the front of the chassis to avoid the vertical movement of the pusher.
