Dongfeng new plugging technology, water plugging, high-temperature thermal vulcanization, pressure resistance, compression resistance and tear resistance
The working principle of water plugging is to use high-quality pipe plugging to shrink it through inflation. When the gas pressure in the water plugging reaches the rule request, the water plugging fills the entire pipe section, and the water leakage is blocked by the friction between the pipe plugging wall and the pipe, so as to achieve the goal of no water seepage in the targeted pipe section.
The models of water blocking are complete and the scope of application is wide, which can be applied to the construction of PE/PVC and other plastic pipes, building risers, municipal sewage pipes, FRP pipes, corrugated pipes, drainage pipes, sewers and other pipes of various materials, as well as the municipal unit management offices, water bureaus, sewage treatment plants, drainage offices and other engineering projects in various provinces and cities, It is mainly used for temporary water plugging and sealing work such as sealing pipeline/pipeline closed water test/pipeline leak detection and maintenance, with quick plugging and good effect.
What are the suitable places for water blocking? Shanghai Dongfeng Pump Valve Factory will introduce you in detail:
1. Municipal sewage pipeline; Basically, the water flow in the sewage pipe is not large. If the drainage pipe of the sewage pipe is blocked or needs to be dredged, then pipe plugging is used to block the pipes at both ends to prevent the water flow back, and then the blocked section of the pipe can be dredged.
2. Check the floor drain; Turn over the floor drain bowl, insert the floor drain, and pour water in the air after inflation. If the floor drain is installed without filling the hole with ash according to the regular tray, water will leak around the floor drain.
3. Pipe plugging of high-rise buildings; The water blocking is delivered from the inspection port, and the water filling inspection is conducted after inflation. If the pipeline has sand holes or the opening is not tight, the leakage can be seen.
4. Closed water test of toilet (building waterproof layer); The closed water experiment of the building waterproof layer requires pipe plugging. When the closed water experiment is done, the pipes in the waterproof layer need to be filled with water, and then the pipe orifice needs to be plugged with pipes. Check whether there is water seepage for 24 hours.
5. Other pipelines; For example, water pipes, gas pipes, gas pipes, rainwater pipes, sewer pipes, chemical pipes, ventilation pipes, etc. are all used in the same way.
