Description

Technical Field

[0001] The utility model relates to the technical field of gate valve detection, in particular to a gate valve air tightness detection device. Background Art

[0002] The gate valve is a gate plate that opens and closes. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened or fully closed, and cannot be adjusted or throttled. During the gate valve production process, the semi-finished parts after the gate valve body and the gate valve cover are assembled need to be tested for air tightness, so as to detect the ventilation condition of the gate valve when it is open and the sealing condition of the gate valve when it is closed.

[0003] For example, the utility model patent with authorization announcement number CN219178853U discloses an air tightness detection device for a gate valve. The device fixes the leakage detection mechanism, the inflation mechanism and the valve body with installation bolts, closes the valve body, and uses the inflation mechanism to inflate one side of the valve body to reach a certain air pressure. After a period of time, it is determined whether there is a leak to meet the purpose of use.

[0004] However, during the specific inspection, the device needs to fix the gate valve with bolts. After the inspection is completed, the bolts need to be removed to remove the gate valve for subsequent inspection. The operation is cumbersome, which reduces the inspection efficiency and cannot meet the use requirements well. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figures 1 to 5 A gate valve air tightness detection device comprises: a detection platform 1, a water tank 11 is embedded at the right position of the upper end of the detection platform 1, and a plurality of partition plates 111 are distributed and installed in the water tank 11, and a clamping frame 12 is also installed at the right half of the upper end of the detection platform 1, and an air guide cover 14 is installed on the clamping frame 12, and an air guide pipe 13 is installed at the other end of the air guide cover 14, and the other end of the air guide pipe 13 extends into the water tank 11; a placing mechanism 4 is slidably installed on the detection platform 1, and is used for placing the gate valve to be detected; a moving mechanism 3 is installed on the detection platform 1, and is used to drive the placing mechanism 4 to move; a clamping mechanism 2 is installed at the left position of the upper end of the detection platform 1, and is used to cooperate with the clamping frame 12 to fix the gate valve.

[0023] The working principle of the utility model: when in use, first fill the water tank 11 with clean water, then place the gate valve to be tested on the placing mechanism 4, the gate valve can be initially fixed, then, the placing mechanism 4 is pushed to move by the moving mechanism 3, so that the right side of the gate valve extends into the air guide cover 14, and then, the clamping mechanism 2 on the left side is moved to the right, so that the gate valve is fixed with the clamping frame 12, and the detection work can be carried out. The operation is simple and the gate valve is convenient to disassemble. The whole process does not need to be fixed by bolts, which can effectively detect the efficiency, thereby better meeting the use requirements.

[0024] As a further solution, the placement mechanism 4 includes a placement base 41 slidably mounted on the detection table 1, a placement support plate 42 is installed at the middle position of the upper end of the placement base 41, and a pair of placement connecting seats 43 are installed on the left and right sides of the placement support plate 42 on the placement base 41, each of the placement connecting seats 43 is provided with a placement slide, and a pair of placement clamping plates 44 are slidably installed in each placement slide, and a placement spring 46 is also installed between the placement clamping plates 44 and the placement slide. In this embodiment, an arc groove is provided on the opposite side of the placement clamping plates 44, and a chamfer 45 is also provided on the upper end of the placement clamping plates 44. By providing the arc groove, it is convenient for the placement clamping plates 44 to better clamp the gate valve, and by providing the chamfer 45, it is convenient for the gate valve to be inserted between the placement clamping plates 44, so that the placement clamping plates 44 can clamp the gate valve.

[0025] The working principle of the placement mechanism 4 is: when placing the gate valve, place the gate valve to the chamfer 45 position at the upper end of the placement clamping plate 44, and then press the gate valve downward. At this time, the gate valve moves downward, and the placement clamping plates 44 on both sides are separated, and the placement spring 46 is compressed. When the gate valve moves to the arc groove position, the placement support plate 42 holds the gate valve. Under the squeezing action of the placement springs 46 on both sides, the placement clamping plates 44 on both sides clamp the gate valve, thereby completing the initial fixation of the gate valve. The operation is simple and the gate valve can be easily taken out to facilitate the replacement of the gate valve.

[0026] As a further solution, the moving mechanism 3 includes a moving slide groove 34 opened at the upper end of the detection platform 1, and a moving slide 33 is slidably installed in the moving slide groove 34. The upper end of the moving slide 33 is fixedly connected to the placement base 41. A moving seat 31 is also installed at the lower end of the detection platform 1, and a moving electric push rod 32 is installed on the moving seat 31. The telescopic end of the moving electric push rod 32 passes through the moving seat 31 and is fixedly connected to the moving slide 33.

[0027] The working principle of the moving mechanism 3 is: by extending the moving electric push rod 32, the moving slide 33 is pushed to the right, thereby driving the placement base 41 to move to the right, and then the right end of the gate valve is extended into the air guide cover 14 and contacts the air guide cover 14, which is convenient for subsequent detection work.

[0028] As a further solution, the clamping mechanism 2 includes a clamping seat 21 installed at the left side of the upper end of the test bench 1, a clamping electric push rod 22 is installed at the upper end of the clamping seat 21, the telescopic end of the clamping electric push rod 22 passes through the clamping seat 21 and is fixed with a clamping push plate 23, a connecting seat 24 is fixed on the right side of the clamping push plate 23, an air guide cover 25 is installed on the right side of the connecting seat 24, the air guide cover 25 is connected to the hollow cavity of the connecting seat 24, an air supply pipe 26 is also installed at the upper end of the connecting seat 24, the air supply pipe 26 is connected to the hollow cavity of the connecting seat 24, and sealing gaskets are installed in the air guide cover 1 14 and the air guide cover 2 25. By providing a sealing gasket, the sealing effect between the gate valve and the air guide cover 1 14 and the air guide cover 2 25 can be improved.

[0029] The working principle of the clamping mechanism 2 is: during detection (the gate valve is in a closed state), the air supply pipe 26 is connected to the external air pump through a pipeline, and the clamping push plate 23 is pushed to the right by the clamping electric push rod 22, so that the air guide cover 25 is buckled on the left side of the gate valve, thereby cooperating with the clamping frame 12 on the right side to clamp the gate valve, completing the further fixation of the gate valve, and then, blowing air into the gate valve through the air pump to observe whether there are bubbles generated in the right water tank 11. If bubbles are generated, it means that the sealing of the gate valve is unqualified. If no bubbles are generated, it means that the sealing of the gate valve is qualified.
