[0025] The following is a more detailed description of the pipe joint with adjustable flow rate for water supply and drainage of the present invention in conjunction with the accompanying drawings and through specific implementation methods.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] See also Figure 1-Figure 5 The pipe joint with adjustable flow rate of water supply and drainage in this embodiment can adjust the water flow rate inside the water pipe joint 1, so that the pressure in the pipeline is maintained within a certain range, improve the fluid delivery efficiency, and prevent the occurrence of fluid impact. It can also monitor the water pressure at both ends of the water pipe joint 1 in real time, which is convenient for automatic control of the water pipe flow rate. In this embodiment, it mainly includes an integrated water pipe joint 1, and both ends of the water pipe are provided with threaded parts 7 that can be connected to the pipeline. A limit block 2 is fixedly provided inside the water inlet end of the water pipe joint 1, and a plurality of through holes 8 for water flow to pass through are evenly distributed on the circumference of the limit block 2, and the inner end of the limit block 2 is a concave cone. The conical structure can make the end of the limit block 2 have a larger space for water flow to pass through.

[0028] An adjusting frame 3 that can slide along the length direction of the pipeline is arranged inside the water pipe joint 1 on the side of the limit block 2, and a slide rail 9 that is slidably connected to the outer ring of the adjusting frame 3 is arranged on the inner wall of the water pipe joint 1. A support frame 10 that fits the concave surface of the inner end of the limit block 2 is coaxially fixed on the end of the adjusting frame 3 at the water inlet end, and a guide rod 11 that is sleeved on the middle part of the adjusting frame 3 at the water inlet end is fixed on the inner wall of the water pipe joint 1. A blocking frame 12 is fixed inside the water outlet end of the water pipe joint 1, and a through hole 13 for water flow to pass through is penetrated on the blocking frame 12 and the adjusting frame 3. A first spring 14 is arranged between the blocking frame 12 and the adjusting frame 3. A control module is also provided.

[0029] When the device is used, it is connected to the pipeline through the threaded portion 7. When the internal pressure of the pipeline is at a normal value, the adjusting frame 3 makes the support frame 10 fit the inner side of the limit block 2 under the action of the first spring 14. In this process, the rotation of the adjusting frame 3 is limited by the slide rail 9, and the swing of the adjusting frame 3 is limited by the guide rod 11. At this time, the adjusting frame 3 can only slide along the length direction of the water pipe joint 1.

[0030] To monitor water pressure in real time. Figure 1 , Figure 3 and Figure 5In this embodiment, a pressure detection unit 6 is also provided on the water pipe joint 1. The pressure detection unit 6 includes a pressure gauge 61 fixedly provided on the outer wall of the water pipe joint 1, and the pressure gauge 61 is centrally controlled by the control module. A water pressure sensor 62 is fixedly provided at the water inlet and the water outlet inside the water pipe joint 1. The water pressure sensor 62 feeds back a signal to the control module. The water pressure at both ends of the water pipe joint 1 is detected by the water pressure sensor 62 and fed back to the control module. This facilitates subsequent operations.

[0031] In order to achieve the regulation of flow rate. In this embodiment, see Figure 2-Figure 4 A flow rate regulating mechanism 4 is provided between the regulating frame 3 and the limit block 2. The flow rate regulating mechanism 4 includes a mounting plate 41 fixedly provided on the regulating frame 3 at both ends of the guide rod 11, and a rubber airbag 42 is fixedly provided on the mounting plate 41. An air pump 43 is fixedly provided on the outer wall of the water pipe joint 1, and the air pump 43 is centrally controlled by the control module. The air pump 43 is a mature prior art and will not be described in detail here. The air pump 43 is connected to the rubber airbag 42 through a hose 44 provided inside the air pump 43 and penetrating the outer wall of the water pipe joint 1.

[0032] When the water flow rate needs to be adjusted, the control module controls the air pump 43 to work, so that the rubber airbag 42 is inflated through the hose 44, so that the space inside the water pipe joint 1 is reduced, and the water flow rate passing through is reduced, thereby changing the water flow rate and the pipeline pressure. In this process, the pressure inside the pipeline is observed in real time through the pressure gauge 61. When the water pressure inside the pipeline is too high, the control module controls the air pump 43 to deflate the rubber airbag 42, so that the space inside the pipeline becomes larger, the circulation speed of the water flow is accelerated, and the pressure is released.

[0033] In order to achieve pressure relief inside the pipeline. Figure 2 , Figure 3 and Figure 5 A blocking mechanism 5 for limiting the adjusting frame 3 is provided on the water pipe joint 1 at the side of the adjusting frame 3. The blocking mechanism 5 includes a warning block 51 fixedly provided on the outer wall of the water pipe joint 1. An iron rod 52 is slidably provided inside the warning block 51 to abut against the side of the adjusting frame 3, and an electromagnet 53 is fixedly provided inside the warning block 51 at the end of the iron rod 52. The electromagnet 53 is centrally controlled by the control module, and the electromagnet 53 is a mature prior art, which will not be described in detail here. A second spring 54 is provided between the electromagnet 53 and the iron rod 52. A warning light 55 is provided at the top of the warning block 51, and the warning light 55 is centrally controlled by the control module.

[0034] When the water pressure inside the water pipe is in a normal state, the adjusting frame 3 is located between the limit block 2 and the iron rod 52, and the position of the adjusting frame 3 is fixed. When the pressure inside the water pipe is too high, the water pressure sensor 62 feeds back a signal to the control module, and the control module controls the electromagnet 53 to work, so that the iron rod 52 overcomes the resistance of the second spring 54 and moves upward, thereby releasing the limit on the adjusting frame 3. At this time, the adjusting frame 3 overcomes the resistance of the first spring 14 under the action of the high-pressure water flow and moves toward the water outlet, thereby reducing the obstruction to the water flow and allowing the pressure inside the water pipe to be released faster. At the same time, the control module controls the warning light 55 to light up and issue a warning to the outside.

[0035] The method of using the pipe joint with adjustable flow rate of water supply and drainage of the utility model is as follows: first, the water pipe joint 1 is connected to the pipe through the threaded part 7. When the internal pressure of the pipe is at a normal value, the adjusting frame 3 makes the support frame 10 fit with the inner side of the limit block 2 under the action of the first spring 14, and the adjusting frame 3 is located between the limit block 2 and the iron rod 52, and the position of the adjusting frame 3 is fixed at this time. When it is necessary to adjust the water flow rate, the air pump 43 is controlled to work through the control module, so that the rubber air bag 42 is inflated through the hose 44, so that the space inside the water pipe joint 1 is reduced, and the water flow passing through is reduced, thereby changing the water flow rate and the pipe pressure. In this process, the water pressure at both ends of the water pipe joint 1 is detected by the water pressure sensor 62, and fed back to the control module. At this time, the internal pressure of the pipe can be observed in real time through the pressure gauge 61. In this process, the water flows out from the water outlet through the pipe perforation and the through hole 13.

[0036] When the pressure inside the water pipe is too high, the water pressure sensor 62 feeds back a signal to the control module, and the control module controls the electromagnet 53 to work, so that the iron rod 52 overcomes the resistance of the second spring 54 and moves upward, thereby releasing the limit on the adjusting frame 3. At this time, the adjusting frame 3 overcomes the resistance of the first spring 14 under the action of the high-pressure water flow and moves toward the water outlet, thereby reducing the obstruction to the water flow and allowing the pressure inside the water pipe to be released faster. At this time, the rotation of the adjusting frame 3 is limited by the slide rail 9, and the swing of the adjusting frame 3 is limited by the guide rod 11. At this time, the adjusting frame 3 can only slide along the length direction of the water pipe joint 1. At the same time, the control module controls the warning light 55 to light up and issue a warning to the outside. In this process, the control module controls the air pump 43 to deflate the rubber airbag 42, thereby enlarging the internal space of the pipeline and accelerating the circulation speed of the water flow to release the pressure.
