Problems solved by technology

[0004] Rubber hoses are usually used in working conditions of uniform pressure such as internal pressure and external pressure. High-pressure rubber hoses are usually designed with multi-layer winding steel wire or braided steel wire reinforcement, while vacuum tubes are usually solved by increasing wall thickness, but their resistance Lateral pressure capability is still very limited and prone to deformation

Embodiment Construction

[0014] The examples listed in the present invention are only used to help understand the present invention, and should not be construed as limiting the scope of protection of the present invention. For those of ordinary skill in the art, without departing from the idea of ​​the present invention, Improvements and modifications are made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0015] Such as figure 1 As shown, the present invention includes a pipe body. The pipe body has a multilayer structure and includes an inner rubber layer 1 arranged inside the pipe body. The inner rubber layer 1 is made of rubber or plastic material, which can be adjusted according to the internal medium of the pipe body. The material and thickness of the inner rubber layer 1 need to be selected and determined for the chemical and corrosive characteristics and chemical or mechanical seal to meet the requ...

Abstract

The invention relates to the technical field of pipelines, in particular to a rubber pipe. The rubber pipe comprises a pipe body which comprises an inner rubber layer made of rubber, a spiral spring is wrapped around the inner rubber layer, and an outer rubber layer made of rubber is wrapped around the spiral spring; furthermore, space among spring wires of the spiral spring is filled with rubber, an inner filled layer is arranged between the inner rubber layer and the spiral spring, and an outer filled layer is arranged between the spiral spring and the outer rubber layer. The rubber pipe can be used for conveying gas or liquid media.

Description

Technical field [0001] The invention relates to the technical field of pipelines, in particular to a rubber tube. Background technique [0002] Compared with plastic pipes, rubber pipes have many special advantages, such as good chemical stability, excellent water resistance, low water permeability, low volume resistivity, etc. Therefore, although the production cost of rubber pipes is higher than that of plastic pipes, there are many There are also wider applications in the field. [0003] Rubber tubes are usually used to transmit gas and liquid media. According to the pressure characteristics of the media, they are often divided into high pressure rubber tubes, ordinary rubber tubes and vacuum rubber tubes. The chemical and corrosive characteristics of the media are subject to different designs and classifications. Respectively meet the different application requirements of acid resistance, alkali resistance, oil resistance, corrosion resistance, etc. [0004] Rubber hoses ar...
