Abstract
The invention discloses an ultra-high pressure quick joint, consisting of a threaded sleeve, a steel ball seat, a shell, a sealing sleeve and a valve core; the shell, the steel ball seat and the threaded sleeve are arranged on the same axis; the shell is connected with the external side of the steel ball seat by a spring I; the steel ball seat is connected with threads of the threaded sleeve; the contact between the valve core and the steel ball seat is a contact between conical surface and line; the middle part of the conical surface of the valve core is provided with a groove which is internally provided with an O-shaped sealing ring; the sealing sleeve is connected with the steel ball seat in a sliding way; the position of the steel ball seat corresponding to the groove on the sealing sleeve is provided with a retaining ring; the valve core is externally sheathed by a spring II which is positioned between the sealing sleeve and the steel ball seat in a hollow way; and the ultra-high pressure quick coupling has high output pressure intensity, good sealing performance and switching function.
Description
Technical field
The present invention relates to a kind of ultra-high pressure quick coupling that cooperates with pipe.
Background technique
Be difficult to find a kind of installation quick in the market, simple to operate, easy to use and super high pressure bend joint with switching function and one.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, and a kind of ultra-high pressure quick coupling is provided, and it is safe and reliable to have sealability, reasonable in design, and installation and removal are simple, and are easy to use and reliable and have a switching function.
Technical solution of the present invention is: a kind of ultra-high pressure quick coupling, comprise swivel nut, steel ball seat, shell, stuffing box gland, spool is formed, shell, steel ball seat, swivel nut is on same axis, shell is connected by spring I in the steel ball seat outside, steel ball seat is threaded with swivel nut, spool contacts for the circular cone upper thread with the steel ball seat touching position, one groove is arranged in the middle of the conical surface of spool, the O RunddichtringO is housed in the groove, stuffing box gland and steel ball seat are slidingly connected, steel ball seat and stuffing box gland upper groove corresponding part are provided with back-up ring, and spool is set with spring II outward, and spring II is between stuffing box gland and steel ball seat.
Above-mentioned ultra-high pressure quick coupling, steel ball seat 12 is 78～85 degree with the conical surface tapering of spool 14 touching positions.
Owing to adopt said structure, spool and steel ball seat touching position adopt conical surface seal, the radial fit soft seal, so output pressure height of the present invention [reaching 200～300MPa], good airproof performance, steel ball seat is not when connecting with pipe, spool and steel ball seat are in closed state under the effect of spring spring II, fluid is closed to this ultrahigh pressure joint,, can be widely used in fields such as boats and ships, petrochemical industry, medical equipment, vehicle manufacturing so the present invention is easy to use and have switching function.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in the figure, a kind of ultra-high pressure quick coupling comprises swivel nut 1, steel ball seat 12, shell 11, stuffing box gland 7, spool 14 compositions, and shell 11, steel ball seat 12, swivel nut 1 are on same axis, steel ball 9 is housed on the steel ball seat 12, steel ball 9 outer shells 11 are fixed, and with spring I 16 and jump ring 10 location, steel ball seat 12 is threaded with swivel nut 1 between shell 11 and the steel ball seat, with rubber o-ring 2 sealings, spool 14 contacts for the circular cone upper thread with steel ball seat 12 touching positions, and the conical surface tapering is 78～85 degree.One groove is arranged in the middle of the conical surface of spool 14, O RunddichtringO 3 is housed in the groove, and stuffing box gland 7 is slidingly connected with steel ball seat 12, and steel ball seat 12 is provided with back-up ring 5 with stuffing box gland 7 upper groove corresponding parts, be set with spring II 6 outside the spool 14, spring II 6 is between stuffing box gland 7 and steel ball seat 12.
During work, steel ball seat 12 is not when connecting with pipe, and spool 14 compresses O RunddichtringO 3 with steel ball seat 12 under the effect of spring II 6, makes the tight steel ball seat 12 of its card be in closed state, fluid is in closes; When steel ball seat 12 with after pipe connects, pipe promotes spool 14 unclamps its right-hand member conical surface and steel ball seat 12, spool 14 is in open mode with steel ball seat 12, fluid flows to the other end from spool 14 and steel ball seat 12 end toper faces.
