Description

Technical Field

[0004] However, this patent uses a support plate to support the pressure gauge.

It also takes multiple measurements to find the faulty pressure gauge. After the pressure gauge is leak-proof, it needs to be manually wiped dry before it can be used. The detection process wastes a lot of time and manpower. Utility Model Content

When the support plate descends and hits the water surface, bubbles are easily generated due to the excessively large contact area with the water surface, which affects the airtightness measurement result.

[0007] Further: the separation mechanism includes a telescopic rod and a separation plate, the two telescopic rods are fixedly connected to one side of the separation plate, and the other end of the telescopic rod is fixedly connected to the inner side of the upper end of the detection pool.

[0008] Furthermore: the gas delivery mechanism includes an air pump and an air delivery pipe, the air pump is fixedly connected to one side of the detection pool, and a plurality of the air delivery pipes penetrate the detection pool and are connected to the air pump.

[0010] Further: the fan is fixedly connected to the upper end of the separation plate and faces the side of the supporting mechanism, and the bubble detector is fixedly connected to the center position of the side of the separation plate.

[0011] Further: the partition plate is distributed between the two pressure gauges.

[0012] Furthermore: evenly distributed legs are provided at the lower end of the detection pool.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] This patent can separate the original bubbles in the detection pool to one side by setting up a separation mechanism, and through the special shape of the support plate, it can avoid the bubbles generated during the impact into the water surface due to the large contact area with the water surface, which affects the leak detection results; the partition plate is convenient for observing several pressure gauges entering the water at the same time, and the pressure gauges are dried by the fan after the leak detection is completed, thereby improving the leak detection efficiency.

[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] Combined with Figure 1 , 3 The utility model provides a pressure gauge sealing leak detection device, including a detection pool 1, the lower end of the detection pool 1 is provided with evenly distributed supporting legs, the inner wall side of the detection pool 1 is fixedly connected with a separation mechanism 2, the separation mechanism 2 includes a telescopic rod 23 and a separation plate 24, two telescopic rods 23 are fixedly connected to one side of the separation plate 24, the other end of the telescopic rod 23 is fixedly connected to the inner side of the upper end of the detection pool 1, the fan 21 is fixedly connected to the upper end of the separation plate 24 and faces the side of the supporting mechanism 4, and the bubble detector 22 is fixedly connected to the center position of the side of the separation plate 24. Before leak detection of the pressure gauge 44, by adjusting the length of the telescopic rod 23, the original bubbles in the detection pool 1 are isolated to the side close to the telescopic rod 23 through the separation plate 24, and there are no bubbles on the opposite side of the bubble detector 22. During detection, the pressure gauge 44 on the supporting mechanism 4 drops below the water surface, and the bubble detector 22 detects whether bubbles are generated. After the detection is completed, the pressure gauge 44 on the supporting mechanism 4 is air-dried by the fan 21;

[0023] Combined with Figure 1-3A gas delivery mechanism 3 is fixedly connected to one side of the detection pool 1, and a supporting mechanism 4 is provided on the opposite side of the gas delivery mechanism 3. A uniformly distributed partition plate 41 is provided on the upper end of the supporting mechanism 4. The partition plate 41 is distributed between two pressure gauges 44 to facilitate observation of the pressure gauge 44 with sealing problems. The gas delivery mechanism 3 includes an air pump 31 and an air delivery pipe 32. The air pump 31 is fixedly connected to one side of the detection pool 1. Several air delivery pipes 32 penetrate the detection pool 1 and are connected to the air pump 31. The supporting mechanism 4 includes a supporting plate 42 and a telescopic column 43. The two ends of the telescopic column 43 are respectively fixedly connected to the supporting plate 42 and the lower end of the detection pool 1. The cross section of the supporting plate 42 is an inverted triangle. The supporting plate 4 2 is provided with a magnetic suction groove at the upper end, and a plurality of pressure gauges 44 are magnetically connected to the magnetic suction groove. The pressure gauge 44 is connected to the gas pipe 32. Before the detection, the pressure gauge 44 is first magnetically sucked on the supporting plate 42, and then connected to the gas pipe 32. The air pump 31 supplies air to the pressure gauge 44 through the gas pipe 32. During this process, the telescopic column 43 descends, and the supporting plate 42 contacts the water surface. Since the cross section of the supporting plate 42 is triangular, it is not easy to generate bubbles. Due to the existence of the partition plate 41, the pressure gauge 44 with sealing problems can be easily observed during the process of the pressure gauge 44 being exposed to water, and the bubble detector 22 can also be displayed to avoid omissions.

[0024] The working principle of this application is:

[0025] Before testing, adjust the length of the telescopic rod 23, isolate the original bubbles in the test pool 1 to the side close to the telescopic rod 23 through the separation plate 24, magnetically absorb the pressure gauge 44 on the supporting plate 42, and then connect it to the air pipe 32, and the air pump 31 supplies air to the pressure gauge 44 through the air pipe 32. During this process, the telescopic column 43 descends, and the supporting plate 42 contacts the water surface. Since the cross-section of the supporting plate 42 is triangular, it is not easy to generate bubbles. Due to the existence of the partition plate 41, the pressure gauge 44 with sealing problems can be easily observed during the process of the pressure gauge 44 being exposed to water. At the same time, the bubble detector 22 can also be displayed to avoid omissions. After the test is completed, the pressure gauge 44 on the supporting mechanism 4 is air-dried by the fan 21. This patent can separate the original bubbles in the detection pool 1 to one side, avoiding the generation of bubbles when the supporting plate 42 enters the water, thereby avoiding affecting the air tightness measurement result. At the same time, this patent can detect multiple pressure gauges 44 at one time, and after the detection, the pressure gauges 44 can be air-dried for subsequent use, and the detection efficiency is high.

[0026] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
