Description

Technical Field

[0001] This application relates to the field of water pipe testing technology, and more particularly to water pipe testing devices. Background Technology

[0002] Traditional testing methods in related technologies have shortcomings. While they are advantageous for single-medium testing scenarios, they struggle to meet the demands of complex testing. Typically, water pipes are either circulated by water or air; frequent disassembly and replacement of pipes can lead to seal failure. The switching process can introduce human error, affecting test accuracy. Furthermore, manual switching of pipes or valves between the air and water circuits is cumbersome and time-consuming. Dual-path independent systems require two sets of power supply units, control valve assemblies, and monitoring instruments, resulting in significant space requirements and high costs, as illustrated by Chinese patent application number 202220694166.8. Traditional devices cannot achieve automatic switching between water and air media within a single test cycle, making it difficult to verify sealing performance under dynamic operating conditions. Therefore, significant deficiencies exist in these related technologies. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] Example 1:

[0024] Reference Figure 1 The water pipe testing device includes a water inlet pipe 1, an air inlet pipe 2, a water and air treatment mechanism 3, and a pressure testing valve 4. The water inlet pipe 1 is connected to a high-pressure water pump 5 and a first one-way valve 6. The air inlet pipe 2 is connected to a high-pressure air pump 10 and a second one-way valve 7. The water and air treatment mechanism 3 is provided with a water inlet channel 8 and an air inlet channel 9, which are respectively connected to the water inlet pipe 1 and the air inlet pipe 2. The output end of the water and air treatment mechanism 3 is connected to the pressure testing valve 4 for testing. The output pipe 16 of the water and air treatment mechanism 3 is also connected to a third one-way valve 11.

[0025] The water pipe testing device includes a first check valve 6, a second check valve 7, and a third check valve 11. The first check valve 6 controls the water inlet pipe 1, the second check valve 7 controls the air inlet pipe 2, and the third check valve 11 controls the opening and closing of the output pipe 16. The high-pressure water pump 5 provides power to the water inlet pipe 1, and the high-pressure air pump 10 provides power to the air inlet pipe 2.

[0026] Reference Figure 2 The water and air treatment mechanism 3 includes a wall 40, a pressing button, a pressing component, and a limiting component 50.

[0027] The pressing button includes a pressing cap 21 and a movable rod 22, with the pressing cap 21 fixedly connected to the top of the movable rod 22. The pressing component includes a pressing part 31, a gasket 32, and a movable plug 33. The pressing part 31 is provided with a first pressing body 34 and a second pressing body 35. A water inlet channel 8 is provided in the first pressing body 34 and connects to the water inlet pipe 1, and an air inlet channel 9 is provided in the second pressing body 35 and connects to the air inlet pipe 2. When the pressing button is applied to the pressing part 31, the pressing component moves up and down within the wall 40 along with the pressing button.

[0028] The wall 40 is provided with a first sliding groove 41, a second sliding groove 42, and a third sliding groove 43, which are used for the movement of the first pressing body 34, the second pressing body 35, and the limiting component 50, respectively. An elastic retaining ring is also provided inside the wall 40 for sealing.

[0029] A water outlet 13 is provided on the side wall of the water inlet channel 8, and an air outlet 14 is provided on the side wall of the air inlet channel 9.

[0030] Reference Figure 3 The limiting component 50 is equipped with upper and lower toothed pillars, including an upper toothed pillar 53 and a lower toothed pillar 54. The upper and lower toothed pillars are mounted on the movable rod 22. The upper toothed pillar 53 is pressed by the pressing cap 21, and the lower toothed pillar 54 is rotatable inside. The meshing of the upper and lower toothed pillars is incomplete, with only the tooth tips partially engaging. The guide ribs 51 behind the two engaging teeth are designed to slide in the same guide groove 52. After the lower toothed pillar 54 slides out of the guide groove 52 after being pushed by the upper toothed pillar 53, the teeth of the lower toothed pillar 54 will slide along the inclined surface of the teeth of the meshing upper toothed pillar 53 due to the action of the spring 55.

[0031] Working principle of the embodiments in this application:

[0032] When the button is pressed down once, the spring 55 is compressed, the water outlet 13 on the side wall of the water inlet channel 8 is closed, and the water path is closed; at the same time, the air inlet pipe 2 connects to the air inlet channel 9, connects to the air outlet 14, and connects to the exhaust pipe 15 set in the second sliding groove 42, and the air path is connected.

[0033] When the key is pressed again and reset upwards, the spring 55 remains in its original state, the water outlet 13 on the side wall of the water inlet channel 8 is connected, the water inlet pipe 1 is connected to the water inlet channel 8, the water outlet 13 is connected to the output pipe 16, and the water path is connected; at the same time, the air outlet 14 of the air inlet pipe 2 is closed, and the air path is closed.

[0034] In summary, this application can meet the requirements of composite testing, realize automatic switching between water and air media, automatically close the water channel when air pressure enters, automatically close the air channel when water pressure enters, and measure the response speed during switching, thus verifying the sealing performance under dynamic operating conditions. This application integrates two traditional independent pump and valve systems into a single module, eliminating the need for frequent disassembly and replacement of pipe fittings and avoiding errors. This application has a simple and compact structure, saves space, is easy to operate and convenient for testing, and provides efficient and accurate measurements. The modular integrated design of the water-air treatment mechanism 3 improves space utilization.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
