[0002] PE water supply pipe, or polyethylene water supply pipe, is a type of pipe used for transporting water, made primarily from polyethylene resin through an extrusion molding process. From the perspective of raw material characteristics, polyethylene has excellent chemical corrosion resistance and can withstand the erosion of various chemicals, making PE water supply pipe suitable for transporting water of different qualities. At the same time, it has good flexibility, making it easy to lay in complex terrain and able to adapt to a certain degree of ground settlement or pipe relocation without easily breaking.

[0003] In terms of performance, PE water supply pipes have excellent low-temperature resistance, maintaining good physical properties even in winter in cold regions to ensure normal water supply;

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a PE water supply pipe for preventing joint bursting, comprising: an explosion-proof device 1, a material filling chamber 101 fixedly connected to the top of the explosion-proof device 1, the material filling chamber 101 being filled with a material that can repair cracks, a material filling device 102 fixedly connected to the top of the material filling chamber 101, the material filling device 102 being triggered when a crack is detected, the material filling device 102 automatically releasing the filling material to quickly repair the damaged area and ensure the continuous and stable operation of the pipeline, and an air tightness detection device 103 fixedly connected to one side of the explosion-proof device 1, the air tightness detection device 103 being able to detect the internal air tightness, issuing an alarm when internal air pressure fluctuations occur to remind maintenance personnel to handle the situation in time, and controlling the material filling device 102 to fill the pipe through an electrical signal;

[0027] The explosion-proof device 1 has a lower housing 2 at its bottom. The lower housing 2 has a filling groove 202 inside. A connecting pipe 201 is fixedly connected to the middle of the lower housing 2. The connecting pipe 201 has slots 203 at both ends. The filling groove 202 can accommodate the filling material of the material filling chamber 101, ensuring that the material is evenly distributed during the filling process. The connecting pipe 201 can be connected to the water supply pipe connection end 301 and is tightly fitted with the fixed opening 204 through the slots 203 to enhance the connection stability.

[0028] The explosion-proof device 1 is provided with fixing nuts 104 at both ends, and the lower housing 2 is provided with fixing holes 204 at both ends. The fixing nuts 104 are tightly connected to the lower housing 2 through the fixing holes 204 to ensure the overall structure is stable.

[0029] The fixing nut 104 and the fixing hole 204 are the same size. The fixing nut 104 is threaded into the fixing hole 204 to form a firm fixing structure and prevent the device from falling off during use.

[0030] The explosion-proof device 1 has pipe connection ends 106 at both ends. A first sealing ring 105 is laid on the top of the pipe connection end 106. The first sealing ring 105 fits tightly with the pipe connection end 106 to ensure the airtightness of the connection and prevent gas leakage.

[0031] A water supply pipe 3 is provided on the pipe connection end 106. A water supply pipe connection end 301 is fixedly connected to the front end of the water supply pipe 3. The water supply pipe connection end 301 and the pipe connection end 106 are tightly fitted by the groove 203 to ensure a firm connection and prevent loosening due to vibration.

[0032] A second sealing ring 302 is laid on the upper part of the water supply pipe connection end 301. The upper and lower ends of the water supply pipe connection end 301 are fixedly connected with buckles 303. The buckles 303 are tightly fitted with the pipe connection end 106 to enhance the connection stability. The second sealing ring 302 further ensures air tightness, prevents water leakage, and ensures the safe operation of the pipeline system.

[0033] The internal filling material of the material filling chamber 101 is polyurethane prepolymer. Polyurethane prepolymer has excellent adhesion and corrosion resistance, and can cure in a short time to fill cracks.

[0034] Working principle: When using this device, the operator first connects the water supply pipe 3 to the pipe connection end 106 of the explosion-proof device 1. The pipe connection end 106 fits tightly with the water supply pipe connection end 301 through the groove 203 to ensure a firm connection. The first sealing ring 105 and the second sealing ring 302 work together to form a double seal, effectively preventing gas and moisture leakage and ensuring that the pipeline system continues to operate stably under high pressure. When the pipeline ruptures, the airtightness detection device 103 senses the change in internal air pressure and then immediately activates the material filling device 102. The material filling chamber 101 quickly releases filling material to fill the rupture. The filling material quickly solidifies to form a strong sealing layer, effectively preventing further leakage of gas and moisture.

[0035] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
