The inner wall of the mounting groove 104 is movably sleeved with a filter plate 401.

[0029] The limiting rod 105 is fixedly mounted on the left inner wall and the right inner wall of the tube body 1 away from the rear end of the bidirectional threaded rod 6. The limiting rod 105 runs through the center of the tube body 1. The outer surfaces of both ends of the limiting rod 105 are movably sleeved with sealing plates 7. The inner parts of the front ends of the two sealing plates 7 are respectively threadedly sleeved on the outer surfaces of both ends of the bidirectional threaded rod 6.

[0030] Two sealing rings 8 are fixedly sleeved on the opposite ends of the two sealing plates 7 respectively. The left inner wall and the right inner wall of the tube body 1 are fixedly installed with fixing plates 101. The two sealing rings 8 are located between the two fixing plates 101 and are on the same axis. The shapes of the two sealing rings 8 match the shapes of the opposite ends of the two fixing plates 101. The outer surfaces of the limiting rod 105 away from the two fixing plates 101 and the outer surfaces of the two-way threaded rod 6 away from the two fixing plates 101 are fixedly sleeved with two sealing circles 103.

[0031] In this embodiment, when the pipe body 1 is in use, after the internal water is filtered by the filter plate 401, it is convenient to filter impurities. When the impurities are accumulated for a long time and attached to the filter plate 401, the water outlet effect is affected and regular cleaning is required. When cleaning, it is necessary to rotate the end of the worm 3 located outside the sealing block 2 clockwise to drive the sealing sleeve 301 to rotate inside the pipe body 1, so as to enhance the sealing between the worm 3 and the pipe body 1 and prevent the water inside the pipe body 1 from flowing out. When the worm 3 rotates, it drives the turbine 601 to rotate, so as to drive the two-way threaded rod 6 to rotate. With the cooperation of the limit rod 105, the two sealing plates 7 are moved in the opposite direction, driving the two sealing rings 8 to be respectively close to the opposite sides of the fixed plate 101, and blocking the fixed plate 101, so as to block the water flow at both ends of the pipe body 1, which is conducive to avoiding the staff from going to the water meter to close the main valve, making the disassembly and cleaning of the filter plate 401 more convenient.

[0032] Embodiment 2, as Figure 1-4 As shown, a plurality of sealing circles 103 are evenly divided into two groups, and the opposite sides of each group of sealing circles 103 are movably mounted on the left inner wall and the right inner wall of the tube body 1 close to the turbine 601, and the left inner wall and the right inner wall of the tube body 1 close to the mounting groove 104 are fixedly mounted with sealing rings 102, and the top of the filter plate 401 is fixedly mounted with a connecting block 4, and the top of the connecting block 4 close to the outer surface of the tube body 1 is movably sleeved with a sealing gasket 5, and the top of the connecting block 4 is connected to the top of the tube body 1 by bolts.

[0033] In this embodiment, when in use, when the worm 3 rotates clockwise to the limit, the water flow at both ends of the tube body 1 is blocked, and then the bolts that install the connecting block 4 and the tube body 1 are rotated to remove, the restriction of the connecting block 4 is released, and the connecting block 4 is taken out upward with the filter plate 401 from the inside of the installation groove 104, so that the filter plate 401 can be cleaned outside the tube body 1. In the cleaning process, the water flow at both ends of the tube body 1 is blocked, and the water near the installation groove 104 is in a static state. The opening of the installation groove 104 is located at the top of the tube body 1. Under the action of gravity, the water will not overflow to the outside of the tube body 1 in large quantities, which is conducive to avoiding the staff from cleaning or collecting water sources, reducing the labor intensity of the staff, and cleaning is completed. After completion, the filter plate 401 is placed back into the installation groove 104, and the connecting block 4 is fixed to the top of the tube body 1 again by bolts. The sealing gasket 5 is deformed by the force between the connecting block 4 and the top of the tube body 1 to reduce the gap between the two and enhance the sealing of the installation. The worm 3 is rotated counterclockwise to cooperate with the two-way threaded rod 6 to drive the two sealing plates 7 and the two sealing rings 8 to move relative to each other, so as to remove the blockage at both ends of the tube body 1.

When cleaning, the end of the worm 3 located outside the sealing block 2 needs to be rotated clockwise to drive the sealing sleeve 301 to rotate inside the pipe body 1, so as to enhance the sealing between the worm 3 and the pipe body 1 and prevent the water inside the pipe body 1 from flowing out. When the worm 3 rotates, it drives the turbine 601 to rotate, which is convenient for driving the two-way threaded rod 6 to rotate, and the limit rod 1 05, the two sealing plates 7 move in opposite directions, driving the two sealing rings 8 to cling to the opposite sides of the fixing plate 101 respectively, blocking the fixing plate 101, thereby blocking the water flow at both ends of the pipe body 1, which helps to avoid the staff from having to go to the water meter to close the main valve, making the disassembly and cleaning of the filter plate 401 more convenient. When in use, when the worm 3 rotates clockwise to the limit, the water flow at both ends of the pipe body 1 is blocked, and then the bolts for installing the connecting block 4 and the pipe body 1 are taken out, the restriction of the connecting block 4 is released, and the connecting block 4 is connected with the filter plate 401. 1 is taken out from the inside of the installation groove 104 upward, which is convenient for cleaning the filter plate 401 outside the pipe body 1. During the cleaning process, the water flow at both ends of the pipe body 1 is cut off, and the water near the installation groove 104 is in a static state. The opening of the installation groove 104 is located at the top of the pipe body 1. Under the action of gravity, the water will not overflow to the outside of the pipe body 1 in large quantities, which is conducive to avoiding the staff from cleaning or collecting water sources and reducing the labor intensity of the staff. After the cleaning is completed, the filter plate 401 is placed back in the installation groove 104, and the connecting block 4 is fixed to the top of the pipe body 1 again by bolts to seal it. The pad 5 is deformed by the force between the connecting block 4 and the top of the tube body 1, reducing the gap between the two and enhancing the sealing of the installation. The worm 3 is rotated counterclockwise to cooperate with the two-way threaded rod 6 to drive the two sealing plates 7 and the two sealing rings 8 to move relative to each other, thereby removing the blockage at both ends of the tube body 1. Under the action of the sealing ring 102, it is convenient to enhance the sealing of the left surface, right surface and installation groove 104 of the filter plate 401. A sealing circle 103 is provided at the position where the two-way threaded rod 6 and the limit rod 105 pass through the tube body 1 to prevent water from not passing through the filter plate 401 and enhance the filtering effect.
