[0022] The following is a more detailed description of the water supply and drainage pipe pressure monitoring connector that is easy to disassemble and assemble according to the utility model in conjunction with the accompanying drawings and through specific implementation methods.

[0023] 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.

[0024] See also Figure 1-Figure 3The water supply and drainage pipe pressure monitoring joint of this embodiment, which is easy to disassemble and assemble, can monitor the water pressure inside the pipe by two ways: short-time monitoring and long-time monitoring, so as to monitor the two water pressures, namely, the calm water pressure and the average water pressure in the pipe, increase the accuracy of water pressure monitoring, facilitate the inspection and maintenance of the pipe, and reduce the labor intensity of the staff. In this embodiment, it mainly includes a test joint 1, and both ends of the test joint 1 are provided with a connecting cavity 2 into which the pipe can be inserted. A sealing gasket 7 is fixedly arranged inside the connecting cavity 2, and a groove of a trapezoidal structure is arranged at the outer end of the sealing gasket 7. Both ends of the test joint 1 are circumferentially evenly provided with fixing bolts 3 that can fix the position of the pipe. The head of the fixing bolt 3 can be inserted into the connecting cavity 2, and the fixing bolt 3 is threadedly connected to the test joint 1.

[0025] When it is necessary to detect or repair the water pressure inside the pipeline, the test connector 1 is connected to the pipeline. At this time, the pipeline is inserted into the connection cavity 2 and abuts against the sealing gasket 7 of the trapezoidal groove structure, and then the position of the pipeline is fixed by the fixing bolt 3, so as to facilitate the detection of the pressure inside the pipeline.

[0026] In order to realize the switch between two water pressure detection modes. Figure 1 and Figure 2 In this embodiment, a blocking mechanism 4 is detachably provided at the end of the test connector 1. The blocking mechanism 4 includes a blocking cover 41 detachably provided with the test connector 1, and fixing holes 42 for inserting fixing bolts 3 are evenly distributed on the outer circumference of the blocking cover 41. A sealing ring 43 that can abut against the sealing gasket 7 is provided at the end of the blocking cover 41, and a sealing ring 44 that can fit the test connector 1 is fixedly provided on the blocking cover 41 inside the sealing ring 43.

[0027] When it is necessary to seal the pipeline to detect the water pressure in a calm state, fit the sealing cover 41 with the test joint 1. At this time, the test joint 1 is located between the sealing ring 43 and the end of the sealing cover 41, and the sealing ring 44 fits with the end of the test joint 1. The sealing cover 41 is fixed to the test joint 1 by inserting the fixing bolt 3 into the fixing hole 42. At this time, the calm water pressure inside the water pipe can be tested. When it is necessary to detect the average water pressure, remove the sealing cover 41 from the test joint 1, and then connect the pipeline to the test joint 1, and then the average water pressure can be monitored.

[0028] In order to perform secondary fixation on the test joint. In this embodiment, see Figure 2 and Figure 3, a limiting mechanism 5 which can be inserted into the connection cavity 2 is arranged inside the other end of the test connector 1. The limiting mechanism 5 includes two screw rods 51 arranged opposite to each other, the ends of the two screw rods 51 can be inserted into the connection cavity 2 and the ends of the two screw rods 51 are fixedly provided with abutment blocks 52, and the two screw rods 51 are respectively threadedly connected to the test connector 1. The threaded rotation directions of the two screw rods 51 are opposite, and the inside of the test connector 1 is provided with adjusting nuts 53 which are respectively threadedly arranged on the opposite ends of the screw rods 51.

[0029] After the water inlet end of the test joint 1 is connected and fixed to the pipeline, the adjusting nut 53 is turned to move the screw 51 on the test joint 1. At this time, the abutment block 52 presses against the inner wall of the pipeline to fix the pipeline for a second time. This is convenient for subsequent testing of the water pressure inside the pipeline to avoid excessive impact of the water flow inside the pipeline causing displacement of the test joint 1, resulting in sealing problems and water leakage at the connection.

[0030] To detect the water pressure inside the pipe. Figure 2 and Figure 3 The middle part of the test joint 1 is provided with a detection mechanism 6 for detecting the internal pressure of the pipeline. The detection mechanism 6 includes a water pressure sensor 61 for the internal water pressure of the test joint 1, which is arranged inside the middle part of the test joint 1, and a water pressure gauge 62 for observing the internal water pressure of the test joint 1 is fixedly arranged at the top of the middle part of the test joint 1. During the detection, the water pressure sensor 61 can be used to feedback the signal to the outside, and the staff can visually check the internal water pressure through the water pressure gauge 62.

[0031] The method of using the water supply and drainage pipe pressure monitoring joint that is easy to disassemble and assemble of the utility model is as follows: First, when it is necessary to detect or repair the water pressure inside the pipe, connect the test joint 1 to the pipe. At this time, the pipe is inserted into the connecting cavity 2 and abuts against the sealing gasket 7 of the trapezoidal groove structure, and then the position of the pipe is fixed by the fixing bolt 3. Then, the adjusting nut 53 is turned to move the screw 51 on the test joint 1. At this time, the abutment block 52 supports the inner wall of the pipe to fix the pipe for the second time, which is convenient for the subsequent detection of the water pressure inside the pipe, and avoids the displacement of the test joint 1 due to excessive impact of the water flow inside the pipe, resulting in sealing problems and water leakage at the connection.

[0032] When it is necessary to seal the pipeline to detect the water pressure in a calm state, fit the sealing cover 41 with the test joint 1. At this time, the test joint 1 is located between the sealing ring 43 and the end of the sealing cover 41, and the sealing ring 44 fits with the end of the test joint 1. The sealing cover 41 is fixed to the test joint 1 by inserting the fixing bolt 3 into the fixing hole 42. At this time, the calm water pressure inside the water pipe can be detected. When it is necessary to detect the average water pressure, remove the sealing cover 41 from the test joint 1, and then connect the pipeline to the test joint 1, and the average water pressure can be monitored at this time. During the detection, the signal can be fed back to the outside through the water pressure sensor 61, and it is convenient for the staff to intuitively check the internal water pressure through the water pressure gauge 62.
