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] See also Figure 1 to Figure 2 The utility model provides a water pressure detection device for testing the sealing performance of a pipeline 20, and the technical scheme is as follows:

[0023] A water pressure detection device for testing the sealing performance of a pipeline 20 comprises a cart 1, a water tank 2, a support frame 3, a water pump 4, and a water pressure gauge 7. The water tank 2 is fixedly mounted on the cart 1, a support plate 5 is fixedly connected to the support frame 3, the water pump 4 is fixedly mounted on the top wall of the support plate 5, a water inlet pipe 11 and a water supply pipe 6 are connected between the water pump 4 and the water tank 2, a regulator 12 is fixedly mounted on the top of the support plate 5, and the regulator 12 is electrically connected to the water pump 4.

[0024] like Figure 1 As shown, when testing, the pipe 20 to be tested is connected to the water supply pipe 6, the water tank 2 is filled with water, and the water pump 4 is manually controlled by the regulator 12 to start and extract water from the water tank 2. The water flow is pressurized by the water pump 4 and flows into the water supply pipe 6, and then flows into the pipe 20. The water flow is pressurized by setting the water pump 4, and the power of the water pump 4 can be adjusted by the regulator 12 to adjust the water flow pressure, and the water pressure can be observed by observing the water pressure gauge 7. There is no need for manual pressurization, and the water pump 4 can be adjusted by the regulator 12 to maintain a stable water flow pressure, which is more convenient to operate.

[0025] like Figure 2 As shown, two support rods 9 are fixedly connected to the top of the water tank 2, and a plurality of spaced arc plates 8 are fixedly installed on the two support rods 9, wherein a mounting seat 10 is fixedly installed on two arc plates 8, and a connecting hole 14 is provided on the mounting seat 10, and one end of the water supply pipe 6 is fixedly connected to the connecting hole 14.

[0026] During the inspection, the pipe 20 to be inspected is connected to the connecting hole 14 and placed on the arc plate 8. If water leakage occurs during the inspection, the leaked water can directly fall into the water tank 2, thereby realizing the recycling of water resources and reducing the waste of water resources.

[0027] An air pump 13 is fixedly mounted on the top wall of the mounting seat 10, and the air pump 13 is electrically connected to the regulator 12. A connecting pipe 15 is fixedly mounted in the connecting hole 14, and a sliding pipe 18 is also slidably mounted on the inner wall of the connecting hole 14. The sliding pipe 18 is sleeved on the outer wall of the connecting pipe 15, and an air bag 17 is provided at one end of the sliding pipe 18. A fixed ring 16 is also provided on the outer wall of the connecting pipe 15, and one end of the air bag 17 is connected to the side wall of the fixed ring 16. An air cavity 19 and an airway are provided on the mounting seat 10, and the air pump 13 is connected to the inside of the sliding pipe 18 through the airway and the air cavity 19.

[0028] When testing, the pipe 20 to be tested is sleeved on the outer wall of the connecting pipe 15, and the pipe 20 is continuously moved into the connecting hole 14, so that one end of the pipe 20 is moved to the airbag 17. At this time, the air pump 13 is started to fill the sliding tube 18 with high-pressure gas, so that the sliding tube 18 moves in the direction of the external airbag 17, and the airbag 17 expands outward. The outer wall of the airbag 17 abuts against the inner wall of the pipe 20. The outer part of the airbag 17 is arc-shaped. The airbag 17 is made of rubber material. Under the push of strong air pressure, a good sealing effect is formed with the inner wall of the pipe 20, which can well seal the water entering the pipe 20 and prevent the water from flowing in the opposite direction, so as to facilitate the testing of the sealing performance of the pipe 20. In addition, through such a setting, the connection between the connecting pipe 15 and the pipe 20 is more convenient, and there is no need to manually tighten the connection.

[0029] like Figure 1 As shown, a valve is also provided at the bottom of the water pressure gauge 7. When the water flow pressure reaches the set detection water pressure, the valve is closed to keep the water pressure inside the pipeline 20 stable.

[0030] like Figure 3 As shown, the regulator 12 is provided with a water pressure regulating button and a start switch of the air pump 13. The water pressure regulating button can be set to slowly increase the water pressure step by step, and the sealing effect of the pipeline 20 under various water pressure indicators can be observed.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
