Description

Composite water pipe

Technical Field

The utility model relates to a bathroom business turn over water pipe, in particular to compound water pipe.

Background

The bathroom water inlet and outlet pipe is mainly used for water inlet of a toilet water tank or inlet and outlet of cold water and hot water of a bathroom device, and is a common bathroom hardware pipe fitting.

Due to the limited space in toilets and for aesthetic reasons, toilets and water heaters are often mounted very compactly, very close to the wall and to the water inlet angle valve on the wall, and even the toilet inlet and angle valve are sometimes completely hidden behind the toilet tank. Admittedly, the toilet is more concise and beautiful, but the water inlet pipe of the toilet needs to be twisted and bent twice or for many times in a narrow space behind the toilet water tank, and the water inlet pipe is easy to lose elasticity and be folded and flattened.

In the case of the water inlet pipe, a relatively large negative pressure is formed in the water inlet pipe when the toilet bowl discharges water due to the fact that the water inlet pipe is arranged between the toilet water tank or the water heater and the water inlet angle valve. The common water inlet pipe is difficult to frequently resist the action of positive water pressure and negative water pressure in two directions, the inherent elasticity and strength of the common water inlet pipe can be gradually lost for a long time, and the common water inlet pipe can be folded and flattened at a bending part in serious cases.

In the bathroom industry, there is a double-layer water pipe formed by sleeving two rubber pipes. During production, the outer pipe is inflated with high pressure air, the inner pipe is inserted into the outer pipe, the outer pipe is deflated, and the outer pipe and the inner pipe are tightened to form the double-layer water pipe. The production mode has many disadvantages, for example, the inner part of the outer pipe has high pressure, if the pipe wall of the outer pipe has a defective wire, the outer pipe is easy to blow and explode, and the outer pipe is usually made of flexible materials with better elasticity due to the need of blowing, so that the outer pipe is softer, the outer pipe cannot be prevented from being folded and flattened, and cannot play an explosion-proof role in use, because the water pipe sometimes has instant water pressure which is larger than the high-pressure air pressure used in the production and manufacturing process. Due to the limitation of the processing mode, the double-layer water pipe can only be produced one section by one section according to a certain length, so that the efficiency is not high during production, and the double-layer water pipe is difficult to be just suitable for one water pipe during use and is very inconvenient.

SUMMERY OF THE UTILITY MODEL
