Problems solved by technology

[0006] 1. The toughness of the PVC pipe is insufficient, and the pipe burst sometimes occurs at the connection between the pipe and the connector during use
[0007] 2. The service life is relatively low, it can only be used for about two to three years, and the tube needs to be replaced
[0008] 3. The pipe is always under water pressure, especially the water inlet pipe at the reverse osmosis membrane filter, because a booster pump is generally installed at the front end of the water inlet pipe of the reverse osmosis membrane filter, so that the water can be well filtered through the reverse osmosis membrane , which causes the water pressure in the pipe to be at a rather high value. Therefore, the pipe needs to have sufficient strength to withstand the water pressure, but if the wall thickness of the single-layer water pipe made of PVC material is made too thin, it cannot withstand it. The pressure of the water will cause the pipe to crack. If the wall of the PVC pipe is made thicker, the toughness of the pipe will be reduced, and the pipe will still be cracked when it is turned or connected with the connector.

Abstract

The invention relates to a flexible pipe, in particular to a flexible pipe for water purifying equipment. The flexible pipe comprises an inner layer pipe and an outer layer pipe. The inner layer pipe is placed inside the outer layer pipe in a sleeved mode. A braiding layer is formed between the inner layer pipe and the outer layer pipe. The braiding layer forms a net shape through a plurality of strands of wire-shaped bodies in a crossing mode and is wound on the outer wall of the inner layer pipe. Wire filaments are made of reinforcing fibers. The wire-shaped bodies are formed by a plurality of wire filament bundles in a combined mode, and each bundle comprises 200-250 wire filaments. The flexible pipe is good in tenacity and high in impact-resisting strength, pipeline breaking cannot be caused when a heavy object runs over a pipeline directly, PE intensity is high, environment-stress-cracking-resisting performance is good, and creep resistance is good.

Description

[0001] technical field [0002] The invention relates to a hose, in particular to a hose used in water purification equipment. Background technique [0003] Water purifiers can be divided into two categories: gradual tightening water purifiers and self-cleaning water purifiers according to the pipeline design level. The traditional water purifier is a gradually tightening type, also known as a progressive water purifier. Its internal pipeline design filter element is loose at the front and tight at the back. It is composed of PP cotton, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and rear activated carbon. , Generally, these 5 stages are connected end to end in turn. There is only one passage in the pipeline in the machine, and the dirt is deposited inside the filter element, which needs to be manually removed and cleaned regularly to ensure the normal operation of the machine. [0004] The other type is a more advanced s...
