Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve pipe fitting detection, in particular to a valve pipe fitting inspection tool. Background Art
[0002] Before the valve pipe fittings leave the factory, it is often necessary to detect their sealing performance to ensure their normal operation and use. The valve pipe fitting inspection tool is a tool used to detect the opening, closing performance and sealing performance of valves and pipe fittings. When testing the sealing performance of valve pipe fittings, an inspection tool is generally used for detection.
[0003] Currently, when using a valve pipe fitting inspection tool, generally the valve pipe fitting is directly connected to the air outlet of the inspection tool, and then air is input into the valve pipe fitting through an air pump to achieve the purpose of detecting its sealing performance. However, in actual operation, since the diameters of valve pipe fittings are not uniform, and some inspection tools can only supply air to valve pipe fittings with a specified diameter. If the diameter difference between the air inlet and the valve pipe fitting is too large, there will be too many gaps, resulting in gas leakage, thus affecting the accuracy of the test results. Moreover, since most inspection tools are connected to the valve pipe fitting through the elasticity of a spring, and due to the elastic characteristics of the spring, when the inspection tool is connected to the valve pipe fitting, the connection force may be affected by external interference factors, resulting in fluctuations in the valve inspection data.
[0004] In summary, the current valve pipe fitting inspection tool still has the following defects during use:
[0005] (1) When connecting valve pipe fittings with different diameters, it cannot expand with the diameter of the valve pipe fitting, resulting in too large a gap between the two, affecting the test results;
[0006] (2) Connecting the valve pipe fitting to the inspection tool using the elasticity of a spring has an unstable phenomenon. Content of the Utility Model

[0030] Referring to Figures 1-4 , which is the first embodiment of the present utility model, a valve pipe fitting inspection tool is provided. This valve pipe fitting inspection tool includes a water tank 1. At the top of the water tank 1, an air supply member 2, a flipping member 3, and an auxiliary member 4 are installed. The auxiliary member 4 is located at the top of the air supply member 2 and is movably connected thereto. The flipping member 3 is located on one side of the air supply member 2 and is movably connected thereto.
[0031] The air supply member 2 includes a first air pump 21 located at the top of the water tank 1. At the top of the output end of the first air pump 21, a sealing member 22 is installed.
[0032] The sealing member 22 includes a second air pump 221 installed on the top of the first air pump 21. The output end of the second air pump 221 is fixedly connected to an air supply pipe 222. At the other end of the air supply pipe 222 and away from the second air pump 221, an airbag 223 is installed. A cavity 224 is formed on one side of the airbag 223. One end of the air supply pipe 222 is connected to the airbag 223 through the cavity 224, which can prevent the connection between the air supply pipe 222 and the airbag 223 from getting stuck with the connection of the valve pipe fitting, so as to ensure that one end of the valve pipe fitting can be more tightly connected to the output end of the first air pump 21.
[0033] A snap ring 225 is installed inside the airbag 223. The airbag 223 is connected to the output end of the first inflator 21 through the snap ring 225, which can achieve the purpose of positioning and prevent the airbag 223 from being inflated on both sides at the same time. In this way, only one side of the surface of the airbag 223 can be inflated, so as to maintain the sealing performance of the connection between the first inflator 21 and the valve pipe fitting. At the same time, the diameter of the output end of the first inflator 21 is different, with its surface diameter being larger than its internal diameter. One end of the valve pipe fitting is sleeved on its smaller diameter surface until the outer end face of its connection part contacts the inner side of the larger diameter, which can ensure the stability when the two are connected. At the same time, a notch for placing the air supply pipe 222 is provided on the port with a slightly larger diameter. In combination with the use of the cavity 224, it can prevent the phenomenon that the air supply pipe 222 gets stuck when the valve pipe fitting is connected to the output end of the first inflator 21.
[0034] The air supply part 2 further includes a connecting plate 23 installed on the surface of the first inflator 21. A sliding rod 26 is fixedly connected to the inner side of the connecting plate 23. There are two groups of sliding rods 26. A positioning plate 24 is movably sleeved on the surface of the two groups of sliding rods 26 and away from the connecting plate 23. A positioning groove 25 is opened on the inner side of the positioning plate 24. One end of the sliding rod 26 away from the connecting plate 23 has a larger diameter, which can prevent the positioning plate 24 from separating from it. And the two groups of sliding rods 26 can ensure the stability of the positioning plate 24 when sliding. At the same time, there are multiple groups of diameters inside the positioning groove 25, and the diameters are arranged in descending order, which can fix valve pipe fittings with different diameters and ensure the stability when connected to the valve pipe fitting.
[0035] A bolt 27 is rotatably connected to the inner side of the connecting plate 23 and at the bottom of the sliding rod 26. The positioning plate 24 is located on the surface of the bolt 27 and is threadedly connected to it. A knob 271 is fixedly connected to the surface of one end of the bolt 27. An annular array of rubber strips is installed on the surface of the knob 271, which can prevent slipping during operation. In addition, the bolt 27 passes through the positioning plate 24 and is threadedly connected to it, used to drive the movement of the positioning plate 24.
[0036] The flipping part 3 includes an electric push rod 31 installed inside the water tank 1. The output end of the electric push rod 31 is fixedly connected to a push plate 32. A hinge plate 33 is installed at the bottom of the push plate 32. The hinge plate 33 is located on both sides of the first inflator 21 and is movably connected to it, used to drive the first inflator 21 to flip, which can facilitate the flipping of the air supply part 2 and make the valve pipe fitting located inside the water tank 1, which is beneficial to the detection of airtightness.
[0037] The auxiliary part 4 includes a positioning rod 41 fixed to the top of the water tank 1. A collar 42 is fixedly connected to the surface of the positioning rod 41. A U-shaped plate 43 is fixedly connected to the bottom of the collar 42. The U-shaped plate 43 is located on the surface of the sliding rod 26 and is movably connected thereto, which can maintain the stability when the air supply part 2 flips, and enables the air supply part 2 to flip around the connection point of the U-shaped plate 43 and the sliding rod 26, so as to maintain the consistency of the valve pipe fitting going underwater. In addition, the inside of the U-shaped plate 43 is hollowed out to avoid the phenomenon that the sliding rod 26 gets stuck with it during the flipping process of the air supply part 2.
[0038] During the use process, one end of the valve pipe fitting to be detected is sleeved on the surface of the airbag 223, and the valve pipe fitting is pushed so that the connected port contacts the inner side of the slightly larger diameter of the first air pump 21. Subsequently, the second air pump 221 is started to inflate the inside of the airbag 223 through the air supply pipe 222, so that the airbag 223 slowly expands until its outer surface is closely attached to the inner side of the valve pipe fitting. In this way, the sealing performance when the two are connected can be ensured, thereby avoiding the phenomenon that there are gaps at the connection of the two, resulting in air leakage, further solving the problem that the current inspection tool cannot connect valve pipe fittings with different diameters, and further avoiding the problem that the measurement result will be affected due to air leakage.
[0039] Subsequently, by rotating the knob 271, the bolt 27 is driven to rotate, and the positioning plate 24 is driven to slowly move towards the valve pipe fitting until the positioning groove 25 inside the positioning plate 24 is firmly attached to the valve pipe fitting, then the positioning of the valve pipe fitting can be completed. In this way, its stability can be increased, thereby avoiding the situation that the pipe fitting moves or loosens during the test process, thus affecting the accuracy of the test data, and this method is simple to operate and reduces the operation difficulty.
[0040] After the valve pipe fitting is installed, the electric push rod 31 can be started to push the push plate 32 to rise, and the first air pump 21 is driven to slowly flip through the hinge plate 33. At the same time, during the flipping process of the first air pump 21, it will slowly flip inside the U-shaped plate 43 through the sliding rod 26 to ensure its stability until the valve pipe fitting is completely immersed in the water tank 1 and the valve pipe fitting is completely submerged in water. At the same time, the first air pump 21 is started to continuously inflate the inside of the valve pipe fitting, and by observing whether there are bubbles generated inside the water tank 1, the detection of it can be completed.
[0041] It should be understood that the use of these embodiments is only for explaining the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
