[0035] The present invention also proposes a method for plugging leaks in a heating pipe network, comprising the following steps:

[0036] S1: Pretreatment: clean the leaking part of the heating pipe network, remove the dirt on its surface, and then use one or more of sandpaper, grinder, and electric grinding wheel to grind the pipe network flat and smooth. Measure the thickness of the pipe network before grinding. If the thickness is less than 1 mm, clean it first. After cleaning, only sandpaper can be used for grinding, otherwise it can be ground with a grinder or electric grinding wheel;

[0037] S2: Select a fixing ring that matches the diameter of the pipe network, and check whether it has defects. If it passes the test, proceed to the next step;

[0038] S3: trimming the stopper, selecting stoppers of different sizes according to the size and shape of the puncture hole, and trimming the stopper to make it fit the puncture hole;

[0039] S4: Preliminary fixation: put the first fixing ring and the second fixing ring on the outside of the heating network pipe, and then fit the stopper to the puncture hole. The material of the stopper is rubber. Then fix the first fixing ring and the second fixing ring to block the puncture hole.

[0040] S5: Tightening and adjusting, rotating the threaded rod, driving the block to move and causing the telescopic rod to contract, the block driving the wedge block to move, causing the wedge block to enter the slot, and then continuing to rotate the threaded rod until the threaded rod cannot rotate, thereby fine-tuning the first fixing ring and the second fixing ring, so that the block is more tightly fixed to the puncture hole;

[0041] S6: Check whether there is leakage at the puncture hole. If there is leakage, re-fix it or continue to rotate the threaded rod for reinforcement. If not, complete the plugging work.

[0042] Working principle: when it is necessary to stop leakage in the pipeline of the heating network, the sealing gasket 5 on the second fixing ring 3 is fitted with the pipeline, and the stopper 16 blocks the leakage hole, and then the first fixing ring 2 is rotated to make the sealing gasket 5 on the first fixing ring 2 fit with the pipeline.

After the block 11 moves beyond the wedge block 17, the wedge block 17 will be reset by the force of the spring 20. When the first fixing ring 2 is rotated until the sealing gasket 5 thereon is in contact with the pipe, the threaded rod is rotated, and the threaded rod drives the clamping block 13 to move and the telescopic rod 6 to contract. The clamping block 13 will drive the wedge block 17 to move, so that the wedge block 17 enters the clamping groove 15, and then the threaded rod is continued to be rotated until the threaded rod cannot rotate, thereby fixing the first fixing ring 2 and the second fixing ring 3, and at the same time blocking the leakage hole on the pipe. There is no need to shut down the water circulation, which will not affect the normal life of the residents, thereby improving the convenience of using the leak-proof device.

For example, it can be a fixed connection; it can be a mechanical connection; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
