By setting the anti-leakage component 13, specifically, the sealing ring 132 is placed in the positioning ring 131, and the sealing ring 133 is placed in the connecting pipe 12, and then the connecting pipe 12 is plugged into the connecting flange 1. After 12 is fixed, the sealing ring 132 can play the first sealing effect, the sealing ring 2 133 can play the second sealing effect, and the sealing ring 14 can play the third sealing effect, thereby realizing the anti-leakage function, ensuring the correct measurement of the ultrasonic water meter 11, and avoiding the waste of water resources. The outer surface of the connecting pipe 12 is threadedly connected with a threaded ring 121, and a plurality of clamping blocks 122 are arranged on the outer side of the connecting pipe 12. The right side of the threaded ring 121 contacts the left side of the clamping block 122, and the bottom of the clamping block 122 contacts the outer surface of the connecting flange 1. The outer surface of the connecting pipe 12 is fixedly connected with a plurality of fixing blocks 123. The fixing blocks 123 are used to support the clamping blocks 122 and enable the left and right sides of the clamping blocks 122 to move in opposite directions. An arc rod 221 is fixedly connected to the bottom of 22, and an arc spring 222 is wound around the outside of the arc rod 221. The left side of the arc spring 222 is fixedly connected to the outer surface of the clamping block 122, and the right side of the clamping block 122 is fixedly connected to the outer surface of the connecting pipe 12. The right side of the arc rod 221 penetrates the connecting pipe 12 and extends to the inside. The arc rod 221 is slidably connected to the connecting pipe 12. By setting the clamping block 122, specifically, when the right side of the connecting pipe 12 contacts the left side of the connecting flange 1, the threaded ring 121 is rotated to move it to the right on the connecting pipe 12, and the right side of the threaded ring 121 pushes the left side of the clamping block 122 upward, so that the clamping block 122 can be tightly clamped with the connecting flange 1, and the connecting pipe 12 and the connecting flange 1 can be quickly connected and installed.

[0029] A specific application of this embodiment is:
[0030] When in use, put the sealing ring 132 into the positioning ring 131, and then put the sealing ring 2 133 into the connecting pipe 12, and then plug the connecting pipe 12 with the connecting flange 1, then the right side of the connecting pipe 12 contacts and squeezes the sealing ring 132, and when the right side of the connecting pipe 12 contacts the sealing ring 14, the sealing ring 14 will be pushed, and the limiting rod 141 will slide in the connecting flange 1 and squeeze the spring 142. When the right side of the connecting pipe 12 contacts the left side of the connecting flange 1, the clamping block 122 will move to the outside of the connecting flange 1, and then rotate the threaded ring 121 to move it to the right on the connecting pipe 12, and the right side of the threaded ring 121 will push the left side of the clamping block 122 upward, so that the clamping block 122 can be tightly clamped with the connecting flange 1, and at the same time, the arc rod 221 moves with the clamping block 122, and the arc spring 222 is stretched, and the connecting flange 1 is clamped by the clamping block 122, so that the connecting pipe 12 and the connecting flange 1 can be quickly connected and installed, which is easy to operate and The sealing ring 132 is pressed against the connecting flange 1 and the connecting pipe 12 is pressed against the sealing ring 132. The sealing ring 132 can play a first sealing effect, and the sealing ring 133 can play a second sealing effect.

When the connecting pipe 12 needs to be disassembled and the sealing ring 132 and the sealing ring 133 are replaced, the threaded ring 121 is rotated in the opposite direction to keep it away from the clamping block 122. The left side of the clamping block 122 is reset under the elastic action of the arc spring 222, and the right side of the clamping block 122 is tilted, so that the fixing of the connecting pipe 12 and the connecting flange 1 is released, and then the sealing ring 14 will push the connecting pipe 12 out under the elastic action of the spring 142, so that the staff can disassemble and replace the sealing ring 132 and the sealing ring 133.
