Plug adapter type infusion hose joint seal ring

Abstract

The invention provides a plug adapter type infusion hose joint seal ring. The upper part of the seal ring is provided with a groove; the lower part of the sectional shape of the seal ring is L-shaped, the upper part of the sectional shape of the seal ring is V-shaped, and the sectional shape of the seal ring is integrally y-shaped. According to the seal ring, the common problems such as less controllable matching gap of two seal rings, high laboriousness of mutual screw-in due to over-small matching gap, unreliable sealing and leakage caused by over-large gap and the like in the prior art are mainly solved. The basic shape of the section of the seal ring is designed to be y-shaped, so that the effective sealing area and the elastic deformation of the two seal rings are effectively increased, the pressing of two joints is more labor-saving, the sealing property is good, and the sealing is reliable.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a sealing ring used for a large-diameter plug-in-rotation hose joint for infusion, and belongs to the field of joint sealing. Background technique [0002] As we all know, the plug-and-turn infusion hose joint is screwed into each other by two joint bodies, and the sealing ring of the joint is compressed by controlling the relative screwing depth, so as to achieve the sealing requirement. However, in the widely used plug-and-turn hose joint sealing form at present, it is common that the matching gap between the two sealing rings is not easy to control. It is very laborious to insert; the gap is too large, and when the two joint bodies are butted, there are phenomena such as unreliable sealing and leakage. This has resulted in the disadvantages of high requirements for machining precision of the joint body and increased cost in actual production. For small diameter joints, the processing accura...

AI Technical Summary

Problems solved by technology

However, in the widely used plug-and-turn hose joint sealing form at present, it is common that the matching gap between the two sealing rings is not easy to control. It is very laborious to insert; if the gap is too large, when the two joint bodies are docked, there will be phenomena such as unreliable sealing and leakage

This has led to the disadvantages of high precision machining of the joint body and increased cost in actual production.

For small diameter joints, the processing accuracy is easier to control, but when the diameter is large, due to the inevitable manufacturing errors of machine tools and tooling, the processing is more difficult
