Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning pipeline detection, in particular to an air-conditioning pipeline sealing detection device. Background Art

[0002] Air conditioning copper pipes are an integral part of air conditioning installation. The cooling and heating processes of an air conditioner are achieved by circulating refrigerant within the pipes. If there are airtightness issues at the welds, refrigerant will leak. Air conditioning copper pipes are welded together, and as we all know, air conditioning requires copper pipes to be airtight. Therefore, airtightness testing is necessary at the welds to ensure air conditioning performance. This testing requires the use of an air conditioning pipe sealing test device.

[0003] For example, the prior art application number CN202320460669.3 is an air-conditioning pipe welding point sealing detection device, which includes: a base, a water pool, a fixing frame, an electric telescopic rod, a clamping mechanism, a heating and cooling device, a thermometer, and a temperature display screen. A water pool is fixedly installed above the base. The fixing frame is fixedly installed above the base, next to the water pool; the electric telescopic rod is vertically arranged, its upper end is fixedly connected to the fixing frame, and its lower end is fixedly connected to a clamping mechanism; the clamping mechanism is directly above the water pool; the heating and cooling device is arranged on the bottom surface of the inner wall of the water pool; the thermometer is installed on the side wall of the water pool for real-time detection of the temperature in the water pool; the temperature display screen is installed on the outer wall of the side wall of the water pool, and the temperature display screen is electrically connected to the thermometer. The clamping mechanism includes a mounting frame, a telescopic rod, a spring, a mounting plate, a first sealing plug, a second sealing plug, an air pump, and a vent pipe;

[0004] The above-mentioned prior art has been found through actual use. It is mainly through inserting a copper tube and fixing it between two elastically retractable sealing plugs, then inflating the copper tube through an air pump, and finally driving the copper tube into a pool through an electric telescopic rod, and judging whether the copper tube is sealed by observing the bubbles in the water; however, this elastic clamping method of the copper tube can easily cause the copper tube to separate from the sealing plug due to the pressure of the gas when the air pump inflates the copper tube, resulting in a gap, resulting in a reduction in the sealing of the copper tube and inaccurate detection results. For this reason, we have improved the above-mentioned solution based on actual usage. Utility Model Content

They are only for the purpose of clearly describing the present embodiment, and do not indicate or imply that the device or element referred to must have a specific orientation. Therefore, they should not be understood as limiting the present application.

[0025] like Figures 1 to 5As shown, an embodiment of the present invention provides an air-conditioning pipe sealing detection device, including a connecting seat 1, a water pool 2 is opened on the upper surface of the connecting seat 1, and two sealing plugs 3 and an air pump 6 are provided at the upper end of the water pool 2 for inflating the copper tube 13, and rubber parts 5 are provided on the inner sides of the two sealing plugs 3, and a driving part 4 is also provided on the upper end of one of the sealing plugs 3; the driving part 4 is composed of a screw 41 for driving one of the sealing plugs 3 to move; the rubber part 5 includes an inner ring 51 and an outer ring 52, and one end of the inner ring 51 is integrally provided with an annular outer ring 52, and the outer ring 52 is fixed to the inner sides of the two sealing plugs 3.

[0026] refer to Figure 1 A control board 7 is fixed to the inner side of the connecting base 1. An electric telescopic rod 8 is also fixed to the inner side of the connecting base 1 through a mounting bracket. A gantry 9 is fixed to the output end of the electric telescopic rod 8. Two sealing plugs 3 are located inside the gantry 9. An electric heating plate 10 is fixed to the bottom wall of the pool 2, and a thermometer 11 is fixed to the inner wall of the pool 2.

[0027] refer to Figure 2 and Figure 3 as well as Figure 4 The top wall of the gantry 9 is provided with a slot 12, within which a screw sleeve 42 slides. A screw 41 is rotatably mounted on one side of the gantry 9 and is threadedly engaged with the screw sleeve 42. The lower surface of the screw sleeve 42 is welded to the upper surface of one of the sealing plugs 3, driving the screw sleeve 42 to move one of the sealing plugs 3. An air pump 6 is bolted to the top of the gantry 9. The output of the air pump 6 is connected to one of the sealing plugs 3 via a hose. The sealing plug 3 is then connected to the inner ring 51 and the outer ring 52. The outer side of one of the sealing plugs 3 is bolted to the inner wall of the gantry 9. The inner sides of both sealing plugs 3 are integrally connected to the outer sides of the inner rings 51. Both inner rings 51 are tapered to accommodate copper tubes 13 of varying diameters. A support tube 53 is located within the inner ring 51, with a tripod 54 secured between the outer surface of the support tube 53 and the inner wall of the inner ring 51. A pressure sensor 55 is secured to one end of one of the support tubes 53.

[0028] Working principle: When using this device, first place the copper tube 13 between the two sealing plugs 3, and then turn the screw 41 in the driving part 4 clockwise to rotate the screw sleeve 42 to move one of the sealing plugs 3 and the rubber part 5 to move toward one end of the copper tube 13. The inner ring 51 in the rubber part 5 will first contact the inner wall of the copper tube 13 and fit tightly against the inner wall of the copper tube 13. In addition, the inner side of the outer ring 52 will respectively press against the two ends of the copper tube 13 to achieve the effect of sealing and fixing the copper tube 13; then start the air pump 6 to inflate one of the sealing plugs 3 to allow gas to enter the copper tube 13; finally, start the electric telescopic rod 8 to push the gantry 9 to drive the copper tube 13 into the water pool 2, and observe whether the copper tube 13 generates bubbles in the water pool 2 to achieve detection;

[0029] Since the outer ring 52 and the inner ring 51 of the rubber member 5 are made of soft silicone, they both have good elasticity and sealing performance and can fit tightly to the inner wall and the port of the copper tube 13. At the same time, the movement of the outer ring 52 and the inner ring 51 is controlled by the screw 41 in the driving member 4. The position of the outer ring 52 and the inner ring 51 has a self-locking effect, which can ensure that the copper tube 13 does not shake during the inflation process and prevent the copper tube 13 from being cracked by the gas pressure, thereby increasing the sealing performance of the copper tube 13 and improving the accuracy of the sealing detection.

[0030] During use, the pressure of the gas in the copper tube 13 can be detected by the pressure sensor 55. When the copper tube 13 is inflated, the pressure will gradually rise. A target pressure value is preset by the control board 7. When the pressure sensor 55 detects that the pressure in the copper tube 13 reaches the set value, the control board 7 cuts off the power supply of the air pump 6 so that the air pump 6 automatically stops inflating, thereby achieving the purpose of controlling the amount of air in the copper tube 13.

[0031] The electric heating plate 10 can heat the liquid in the water pool 2, and the sealing condition of the copper tube 13 in different temperature environments is observed in real time. Finally, the copper tube 13 is separated from the water pool 2 by activating the electric telescopic rod 8, and one of the sealing plugs 3 is moved away from the copper tube 13 by turning the screw 41 counterclockwise to remove the copper tube 13 to complete the inspection;

[0032] When the screw rod 41 rotates clockwise or counterclockwise, the distance between the two sealing plugs 3 can be flexibly controlled, so that the copper tubes 13 of different lengths can be clamped and fixed, thereby increasing adaptability.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
