Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a quick-connect sealing structure for a fluid valve. Background Technology

[0002] As a key control component in media conveying systems, the sealing performance and ease of assembly / disassembly of fluid valves connected to conveying hoses directly impact system operating efficiency and maintenance costs. Currently, most fluid valve-to-hose connections employ traditional threaded fastening or clamp locking structures. The former requires multiple rotations with tools for tightening, resulting in low assembly efficiency and a tendency for thread wear to cause seal failure after prolonged use. While the latter offers slightly faster assembly / disassembly, the clamping force is difficult to control precisely; excessive looseness leads to media leakage, while excessive tightness can cause hose compression and breakage, shortening service life.

[0003] To address the aforementioned issues, there is an urgent need for a quick-connect sealing structure that is simple in structure, easy to assemble and disassemble, and has reliable sealing capabilities. This would solve the problems of low efficiency, poor sealing, and easy damage to hoses in existing connection methods, and meet the needs of rapid assembly and maintenance in fluid transportation scenarios.

It can effectively fill the gap between the hose and the valve body, significantly improve the sealing performance, and reduce the risk of media leakage.

[0015] 3. Protect the hose structure and extend its service life: The design of the arc surface and the matching clamping part can avoid local stress concentration on the hose and prevent hose damage and cracking caused by uneven clamping force in traditional fastening methods; at the same time, the matching structure of the groove and the collar provides auxiliary limit for the hose end, reducing stress damage to the hose during assembly and use, and extending the service life of the hose.

[0016] 4. Simple and compact structure with strong adaptability: The quick-connect sealing structure consists of only a threaded sleeve, pressure ring, and nut.
