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.

Embodiment 1

[0047] see Figure 2-3 , a hydraulic high-stability rubber hose joint, including a hydraulic variable tube and an outer casing 2 sleeved outside the hydraulic variable tube, the hydraulic variable tube includes a fixed rod 11 and a pressure variable tube 12 fixedly connected to the right end of the fixed rod 11, Both the fixed rod 11 and the outer casing 2 are of hard structure, and the pressure variable tube 12 is an elastic sealing structure, so that the pressure variable tube 12 can change to the shape under the pressure of the fluid, squeeze the rubber tube, and make the gap between the rubber tube and the joint The connection strength of the fixed rod 11 close to the outer end of the pressure variable tube 12 is fixedly connected to the limit washer 4, the sliding end of the pressure variable tube 12 is located on the left side of the limit washer 4, and the outer end of the pressure variable tube 12 is excavated with a A plurality of evenly distributed inset ring wedge g...

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. [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 permea...
