Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, in particular to a sealing detection device used for valve processing. Background Art

[0002] In order to detect whether the valve is sealed after processing, the sealing of the valve is usually tested by a detection device. After searching, the Chinese patent publication number CN216621636U discloses a detection device for valve sealing. Although the device forms a high-pressure water environment inside the valve by injecting water into the valve and increasing the pressure, the sealing of the valve is judged by observing whether there is water seepage on the valve surface, and the valve leakage point can be accurately marked to facilitate subsequent processing, but it is not intuitive to observe whether there is water seepage on the valve surface to judge whether the valve is sealed. In addition, the back of the valve cannot be directly observed by the naked eye, which easily affects the judgment of the valve sealing. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a sealing detection device for valve processing, which solves the problem that the existing device proposed in the background technology judges whether the sealing of the valve is qualified by observing the valve surface with the naked eye to see whether there is water leakage, which is not intuitive enough and easily affects the judgment of the valve sealing.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sealing detection device for valve processing, comprising a device body, a first control valve, a base and a second pressure gauge, an air pump is provided on one side of the device body, the external output end of the air pump is connected to one end of the first control valve, the other end of the first control valve is connected to the interior of the base, the base is fixedly installed inside the device body, and a hole groove is provided on the top of the base, the hole groove on the top of the base is connected to the interior of the base, a hydraulic cylinder is installed on the top of the device body, a pressure plate is provided on the outside of the telescopic end of the bottom of the hydraulic cylinder, a rubber block is bonded to the bottom of the pressure plate, a second pressure gauge is provided at the other end of the device body, the detection end of the second pressure gauge is located inside the device body, a sealing door is provided on the front of the device body, and one end of the sealing door is rotatably connected to the device body.

[0005] Preferably, the top surface of the base is made of rubber material, and the diameter of the base is larger than the outer diameters of both ends of the detection valve. The rubber material is helpful in improving the sealing performance of the bottom end of the valve.

[0006] Preferably, a first pressure gauge is provided outside the pipe connecting the first control valve and the base, and a detection end of the first pressure gauge is located inside the pipe. The first pressure gauge can be used to observe whether the pressure inside the valve changes when maintaining pressure.

[0007] Preferably, the connecting pipe between the air pump and the first control valve is connected to one end of the second control valve, and the other end of the second control valve is connected to the interior of the device body. By opening the second control valve and closing the first control valve, gas can be filled into the interior of the device body to maintain pressure, so that the sealing performance of the sealing door of the device body can be judged by the second pressure gauge.

[0008] Preferably, two grooves are provided on one side of the sealing door, and a threaded rod is provided inside the groove. The outside of one end of the threaded rod is threadedly connected to the inside of the fastener, and the other end of the threaded rod is welded to one side of the device body. By closing the sealing door, the two fasteners can be fitted onto the outside of the threaded rod. By rotating the fasteners, the fasteners can press the sealing door, so that the sealing door can maintain a close fit with the device body, thereby maintaining a high degree of sealing inside the device body.

[0009] The utility model provides a sealing detection device for valve processing, which has the following beneficial effects:

[0010] (1) The sealing detection device for valve processing, when in use, is placed between the base and the rubber block, and then the rubber block is pushed downward by the action of the hydraulic cylinder, so that the two ends of the valve can be sealed by the action of the rubber block and the base, and then the air pump can be used to pump gas into the base. The gas enters the valve through the hole groove on the top surface of the base, and then closes the first control valve, so that the cavity inside the valve can maintain pressure. During the pressure maintenance process, the sealing of the valve is judged by observing whether the values ​​of the first pressure gauge and the second pressure gauge change, which is conducive to intuitively seeing whether the sealing of the valve is qualified through the first pressure gauge and the second pressure gauge.

[0011] (2) The sealing detection device for valve processing closes the sealing door, thereby enabling the two fasteners to be mounted on the outside of the threaded rod, and by rotating the fasteners, the fasteners can press the sealing door, so that the sealing door can maintain a close fit with the device body, thereby enabling the inside of the device body to maintain a high sealing performance, and thus the value detected by the second pressure gauge has a high accuracy in judging the sealing performance of the valve.

[0012] This solves the problem that the existing device judges whether the valve sealing is qualified by visually observing whether the valve surface has water seepage, which is not intuitive enough and easily affects the judgment of the valve sealing. BRIEF DESCRIPTION OF THE DRAWINGS

A first pressure gauge 4 is provided outside the connecting pipe between the first control valve 3 and the base 8, and the detection end of the first pressure gauge 4 is located inside the pipe. The connecting pipe between the air pump 2 and the first control valve 3 is connected to one end of the second control valve 13, and the other end of the second control valve is connected to the inside of the device body 1. When the device is in use, the valve is placed between the base 8 and the rubber block 12, and then the rubber block 12 is pushed downward by the action of the hydraulic cylinder 9, so that the two ends of the valve can be sealed by the action of the rubber block 12 and the base 8, and then the air pump 2 can pump gas into the base 8. The gas enters the valve through the holes on the top surface of the base 8, and then closes the first control valve 3, so that the cavity inside the valve can maintain pressure. During the pressure maintenance process, the sealing of the valve is judged by observing whether the values ​​of the first pressure gauge 4 and the second pressure gauge 10 change, which is conducive to intuitively seeing whether the sealing of the valve is qualified through the first pressure gauge 4 and the second pressure gauge 10.
