Hydraulic high-stability rubber hose connector

Abstract

The invention discloses a hydraulic type high-stability rubber pipe joint, and belongs to the field of pipe joints. According to the hydraulic type high-stability rubber pipe joint, through the arrangement of a hydraulic variable pipe, when fluid passes through, the hydraulic variable pipe extrudes a rubber pipe and expands towards the inner wall of an outer sleeve shell under the action of fluid pressure, an outer top ring wedge extrudes the rubber pipe, at the moment, the rubber pipe is locally deformed and falls into a corresponding concave ring wedge groove, connection between a fastening rubber pipe and the connector is extruded through the pressure of the fluid, the effect that the connection stability between the fastening rubber pipe and the connector is higher along with the increase of the liquid pressure is achieved, compared with the prior art, the situation that the connector is loosened due to liquid impact force is effectively avoided, in addition when the rubber pipe and the connector are accidentally loosened, the sealing performance is weakened, part of the fluid permeates into an early warning ring groove along a liquid guide layer, the color of a developing point is changed, therefore early warning is conducted on workers, and the occurrence rate of the pipe explosion phenomenon is reduced through timely maintenance.

Description

technical field [0001] The invention relates to the field of pipe joints, in particular to a hydraulic high-stability rubber pipe joint. Background technique [0002] A type of tubular rubber product used to convey gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layers and a skeleton layer. The material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Generally, the inner and outer rubber layers of rubber hoses are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant hoses are made of neoprene and nitrile rubber; acid-resistant and high-temperature resistant hoses are made of ethylene-propylene rubber, fluorine rubber or silicone rubber.

Problems solved by technology

[0003] In the liquid transportation system, whether it is a metal pipe joint or a hose joint, there is a problem of easy leakage, especially when transporting liquid with strong fluidity. Due to its high permeability, it is easier to leak, and the pipeline is subject to greater The external force or the impact force from the liquid will cause the joint to loosen and cause leakage. When the liquid impact force is too large, the joint may even fall off and explode, causing great difficulty in maintenance.
