A hydraulic type high stability rubber hose joint

Abstract

The invention discloses a hydraulic type high-stability rubber hose joint, which belongs to the field of pipe joints. A hydraulic type high-stability rubber hose joint, through the setting of a hydraulic variable tube, when the fluid passes through, the pressure variable tube squeezes under the action of the fluid pressure Press the rubber hose and expand toward the inner wall of the outer casing, so that the outer top ring wedge squeezes the rubber hose. At this time, the rubber hose is partially deformed and then falls into the corresponding indented ring wedge groove, so that the rubber hose and the joint can be squeezed and fastened by the pressure of the fluid itself. The connection between the two achieves the effect of higher connection stability as the liquid pressure increases. Compared with the existing technology, it effectively avoids the joint loosening caused by the impact of the liquid. In addition, when the rubber hose After accidental loosening with this joint, the sealing becomes weak, and part of the fluid seeps into the early warning ring groove along the liquid guide layer, causing the color point to change color, so as to give early warning to the staff, and reduce the incidence of pipe burst 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.
