Description
Technical Field
The utility model relates to a bathroom business turn over water pipe, in particular to anti negative pressure business turn over water pipe of rolling over is used in kitchen guarding.
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 common bathroom hardware.
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.
The water inlet pipe is arranged between a toilet water tank or a water heater and a water inlet angle valve, so that the water inlet pipe needs to withstand higher water pressure at ordinary times, and the high positive water pressure resistance is the most basic requirement. However, the toilet bowl may form a large negative pressure in the water inlet pipe when discharging water. The general water inlet pipe is difficult to frequently bear the action of positive water pressure and negative water pressure in two directions, the inherent elasticity and strength of the water inlet pipe can be gradually lost after a long time, and the water inlet pipe can be directly burst by the positive water pressure or be folded and flattened at a bent part in serious conditions.
In addition, the existing water inlet and outlet pipes of the bathroom are generally manufactured into a single pipe according to a certain length. When in use, the water pipe is difficult to be just suitable for one water pipe, and is very inconvenient.
In addition, in the bathroom industry, a double-layer water pipe formed by sleeving two rubber pipes is further provided. 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 flaw wires, the outer pipe is easy to blow and explode, and the outer pipe is usually made of flexible materials with better elasticity by 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 higher 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 at a time according to a certain length, so that the efficiency is not high during production, and the double-layer water pipe is very inconvenient because the double-layer water pipe is difficult to be suitable for one water pipe when in use.
