PE water supply pipe

Abstract

The invention belongs to the technical field of pipe manufacturing, and particularly relates to a PE water supply pipe which comprises a main body, a PE pipe and a protection mechanism. The main body is composed of a normal water hose, the inner surface of the main body is fixedly sleeved with a PE pipe, and the main body is stored in a winding roller mode; a protection mechanism is arranged in the PE pipe; the protection mechanism comprises a mounting ring, an elastic ring, a special-shaped groove, a corrugated ring, a vibration cavity and bristles; the mounting rings are embedded and fixedly mounted in the wall of the PE pipe at fixed intervals, and the mounting rings are connected through the elastic rings; when the PE pipe is released, the PE pipe cannot be folded like a water hose, so that high-pressure water flow which is going to pass next cannot be blocked, the PE pipe can only have a storage action through the design, the PE pipe can be automatically released by virtue of the elasticity of the PE pipe during release, the effect of quickly paving the PE pipe can be achieved, and the service life of the PE pipe is prolonged. And the physical strength of the firefighter can be saved to a certain degree, so that the following more important fire extinguishing task is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pipe material manufacturing, in particular to a PE water supply pipe. Background technique [0002] Water supply pipes are divided into metal pipes, composite pipes and plastic pipes. Metal pipes are mainly divided into copper pipes and stainless steel water pipes. Metal pipes have many characteristics such as safety, sanitation, and durability. , has been gradually eliminated; the most commonly used plastic pipes are PPR water pipes, which are safe, non-toxic, easy to install, low in price and many other reasons, making them the most commonly used water pipes for home improvement. However, due to problems such as environmental hormones, more and more people are beginning to use metal pipes or ppr-lined metal pipes as water supply pipes; the performance indicators of water supply pipes are relatively strict, especially for drinking water, which requires pipes to have Non-toxic and radiation-free, no har...

Problems solved by technology

[0003] In the prior art, when a fire breaks out in a city, the firefighters drive the fire truck to put out the fire. When the fire truck arrives at the scene, the firefighters need to lay the fire pipes immediately. However, the existing fire pipes are usually composed of hoses. The hose is chosen as the first choice for fire extinguishing due to its excellent folding performance, which makes its footprint small and easy to carry. However, the hose will be rolled up when it is not in use, so that the hose is generally flat. Therefore, when using it, it is necessary to quickly unfold it to pass water to realize fire extinguishing and firefighting, and the time of firefighting is a very important indicator, so when the hose is unfolded, the firefighters will consume a lot of energy, which is not conducive to the follow-up At the same time, because the hose is too soft, it will inevitably fold together even if it is unfolded. This situation will make the hose bend at a right angle, and then seal the pipe, so the water pressure sprayed in an instant Under the action of the hose, the front end of the hose will swing, and the metal pipe connected to the front end of the hose will hit the rescuers, which is very unfavorable for use.
