Description

Technical Field

[0001] The present application relates to the technical field of pipeline quality detection, and in particular to a device for detecting the quality of a water supply pipeline. Background Art

[0002] Water supply pipes refer to pipes used to transport water and are an important part of the water supply system.

[0003] To ensure that water can flow out normally during use, pressurized water supply is usually used. This will cause the water in the water supply pipe to have a certain pressure, which will put a load on the water supply pipe. Therefore, during the construction process, the water supply pipe project needs to be quality inspected to ensure the normal operation of the water supply system.

[0004] To ensure the safety of water supply pipelines under fixed pressure and prevent problems such as leaks and ruptures, pipes are typically tested with water. During testing, if water is simply passed through a pipe section, with water flowing in at one end and out the other, the water exerts less pressure on the pipe, resulting in inaccurate test results. This may not accurately reflect the pipeline's true performance under high-pressure conditions, and potential risks of leaks or ruptures may not be discovered in a timely manner, making it impossible to effectively ensure the normal operation of the water supply system.

[0040] To ensure the safety of water supply pipelines under fixed pressure and prevent problems such as leaks and ruptures, pipes are typically tested with water. During testing, if water is simply passed through a pipe section, with water flowing in at one end and out the other, the water exerts less pressure on the pipe, resulting in inaccurate test results. This may not accurately reflect the pipeline's true performance under high-pressure conditions, and potential risks of leaks or ruptures may not be discovered in a timely manner, making it impossible to effectively ensure the normal operation of the water supply system.

[0041] In response to the above problems, an embodiment of the present application provides a device for detecting the quality of water supply pipes, which can detect the quality of water supply pipes under stable water pressure and water flow, and effectively ensure the normal operation of the water supply system.

[0042] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0044] Figure 2 Schematic diagram of a water supply pipe section assembly in a water supply pipe quality detection device according to this embodiment;

[0045] Figure 3 This is a schematic diagram of the internal structure of the connection warehouse in this embodiment.

[0046] See also Figure 1-3 A device for detecting the quality of a water supply pipeline, for detecting the quality of a water supply pipeline, comprising:

[0047] A water tank 1 has a top and a bottom on one side of the water tank 1 fixedly connected with a return pipe 2 and a water supply pipe 3 communicating therewith.

[0048] Specifically, a water inlet 17 is provided on the top surface of the water tank 1 , and a drain valve 18 is fixedly installed on the bottom of the water tank 1 .

[0049] A water inlet 17 is provided to facilitate the injection of water into the water tank 1 ; a drain valve 18 is provided to control the discharge of water in the water tank 1 .

[0050] Specifically, a push handle 15 is fixedly connected to the other side of the water tank 1 , and casters 16 are fixedly installed at the four corners of the bottom surface of the water tank 1 .

[0051] By providing the push handle 15 and the casters 16, the water tank 1 can be easily moved and the construction is convenient.

[0052] The water supply pipe 3 is connected to a first connecting pipe 4, at the end of which is connected a circulation pump 5. The return pipe 2 is connected to a second connecting pipe 6, at the end of which is fixedly connected a water outlet pipe 7, which is fixedly connected to the water outlet of a connecting chamber 8. The water inlet of the connecting chamber 8 is fixedly connected to a water inlet pipe 9, which is installed at both ends of a water supply pipe 10 along with the circulation pump 5. Each pipe is fixedly connected via flanges and bolts. Both the first connecting pipe 4 and the second connecting pipe 6 are flexible hoses, facilitating pipe laying and connection.

[0053] By connecting the water supply pipe 3, the first connecting pipe 4, the circulation pump 5, the water supply pipe 10, the connecting bin 8, the water outlet pipe 7 and the return pipe 2 in sequence, the circulation pump 5 can be driven to draw the water in the water tank 1 through the water supply pipe 3 and finally discharge it back into the water tank 1 through the return pipe 2, forming a water circulation loop for detecting the water supply pipe 10.

[0054] Specifically: a water pressure gauge is installed on the water inlet pipe 9.

[0055] By installing a water pressure gauge on the water inlet pipe 9 , the pressure inside the water inlet pipe 9 can be monitored in real time, thereby monitoring the internal pressure of the water supply pipe 10 .

[0056] A closing plug seat 11 is fixedly installed inside the connecting bin 8 at one end corresponding to the water inlet pipe 9, and a closing plug head 12 that is compatible with the closing plug seat 11 is provided on the side of the closing plug seat 11 close to the water outlet pipe 7. The end face of the closing plug head 12 is fixedly connected to a guide wing 13 that fits and moves with the inner wall of the connecting bin 8. A spring 14 is provided between the guide wing 13 and the inner wall of the end of the connecting bin 8, and an adjustment mechanism is provided between the end of the spring 14 and the connecting bin 8.

[0057] Specifically, the guide fin 13 is in a M-shape, and a groove adapted to the spring 14 is provided on the top surface of the guide fin 13 to facilitate the placement and positioning of the spring 14 .

[0058] The adjustment mechanism includes: an adjustment plate 19, a hole plate 20, a threaded sleeve 22, a threaded handle 23 and a connecting rod 24, wherein:

[0059] The adjustment plate 19 and the orifice plate 20 are fixedly installed on the top and bottom of the connecting rod 24 respectively. The adjustment plate 19 is slidably connected to the inner wall of the connecting chamber 8, and the orifice plate 20 is slidably connected to the inner wall of the connecting chamber 8; wherein, the adjustment plate 19 is slidably connected to the inner wall of the connecting chamber 8 through a sealing ring, and is slidably sealed with the inner wall of the connecting chamber 8.

[0060] The threaded sleeve 22 is fixedly mounted on the top end surface of the adjustment plate 19 , and the threaded handle 23 passes through the top of the connection chamber 8 and is installed and connected to the threaded sleeve 22 by means of a threaded connection.

[0061] Within the connection chamber 8, the spring 14 is limited by the adjustment mechanism. The spring 14 compresses the guide wing 13, causing the closing plug 12 to be pressed against the closing plug seat 11. Therefore, a certain pressure is required to overcome the compression of the spring 14 for water to pass through. By pushing the closing plug 12 and compressing the spring 14 upward, the water can pass through the closing plug seat 11 and then flow into the outlet pipe 7 through the orifice plate 20 in sequence. Therefore, by cooperating with the circulating pump 5 to continuously inject water into the water supply pipe 10 section, the water pressure inside the water supply pipe 10 section is increased until the water can pass through the connection chamber 8. At this time, the water pressure inside the water supply pipe 10 section is stable, so the quality of the water supply pipe 10 under stable water pressure and water flow can be tested.

[0062] At the same time, by setting up an adjustment mechanism, by rotating the threaded handle 23, the threaded sleeve 22 can be cooperated to drive the adjustment plate 19 to slide up and down, and then the orifice plate 20 is driven to adjust its position in the connecting chamber 8 through the connecting rod 24, thereby controlling the compression of the spring 14, and cooperating with the pressure gauge on the water inlet pipe 9 to accurately adjust the water outlet pressure of the water supply pipe 10 section.

[0063] Specifically, the adjustment mechanism further includes a guide rod 21 that is slidably mounted on the adjustment plate 19. At least two guide rods 21 are provided and are arranged circumferentially on the adjustment plate 19. The guide rods are slidably mounted on the adjustment plate 19 through a sealing ring, and are slidably connected to and sealed against the adjustment plate 19.

[0064] By providing the guide rod 21 , when the adjustment plate 19 is driven to slide, the sliding stability of the adjustment plate 19 can be further guaranteed, thereby better controlling the pressure in the pipeline.

[0065] The use process of the device for detecting the quality of water supply pipes in the embodiment of the present application is as follows:

[0066] Fill the water tank 1 with water through the water inlet 17, and move the device to the selected water supply pipe 10 section to be tested by using the push handle 15 and the casters 16; connect the circulation pump 5 and the water inlet pipe 9 to the two ends of the water supply pipe 10 section respectively, and start the circulation pump 5 at this time, so that the water in the water tank 1 is pumped out through the water pipe 3 and the first connecting pipe 4, and the pumped water is transported to the water supply pipe 10 section through the circulation pump 5. The pressure in the water supply pipe 10 section rises, and the water enters the water inlet pipe 9. The water is squeezed out by the pressure. The closing plug 12 is pressed, thereby compressing the spring 14, overcoming the elastic force of the spring 14 so that the closing plug 12 slides in the connecting chamber 8 through the action of the guide wing 13 and moves away from the closing plug seat 11. At this time, the water can pass through the connecting chamber 8, and then flow back to the water tank 1 through the outlet pipe 7, the second connecting pipe 6 and the return pipe 2 to be extracted again, so that the flowing water with a fixed water pressure is maintained in the water supply pipe 10 section, and the water delivery state is simulated, so as to detect the situation of the water supply pipe 10 section under the pressurized water supply state.

[0067] The technical solution of the embodiment of the present application has the following beneficial effects:

[0068] In this application, after the water supply pipe 3, the first connecting pipe 4, the circulation pump 5, the water supply pipe 10, the connecting bin 8, the water outlet pipe 7 and the return pipe 2 are connected in sequence, the circulation pump 5 is driven to extract the water in the water tank 1 through the water supply pipe 3, and finally discharge it into the water tank 1 again through the return pipe 2, thereby forming a water circulation loop for detecting the water supply pipe 10.

[0069] The present application sets an adjustment mechanism limit spring 14 in the connecting chamber 8. The spring 14 will squeeze the guide wing 13, so that the closing plug 12 is squeezed on the closing plug seat 11, so that a certain pressure is required for the water to pass through to overcome the squeezing of the spring 14. By cooperating with the circulating pump 5, water is continuously injected into the water supply pipe 10 section, so that the water pressure inside the water supply pipe 10 section is increased until the water can pass through the connecting chamber 8. At this time, the water pressure inside the water supply pipe 10 section is stable, and the quality of the water supply pipe 10 under stable water pressure and water flow can be detected.

[0070] The present application sets up an adjustment mechanism, and by rotating the threaded handle 23, it can cooperate with the threaded sleeve 22 to drive the adjustment plate 19 to slide up and down, and then drive the orifice plate 20 to adjust its position in the connecting chamber 8 through the connecting rod 24, thereby controlling the compression of the spring 14, and cooperating with the pressure gauge on the water inlet pipe 9 to accurately adjust the water outlet pressure of the water supply pipe 10 section.
