Abstract
The utility model relates to a loose joint mechanism for a valve, comprising a screw cap, a loose joint and a sealing gasket, wherein the screw cap is provided with internal threads and an inner boss which is arranged at the upper end part and protrudes inwards; the loose joint is pipe-shaped and is provided with external threads at the upper end part; the lower end part of the loose joint is arranged in the screw cap; the sealing gasket is arranged in the screw cap and attached to the lower end surface of the loose joint; and the loose joint is provided with an outer boss outward protruding at the lower end part of the screw cap. The outer boss and the screw cap at the lower end part of the loose joint and the sealing gasket are mutually matched, therefore, the loose joint mechanism eliminates the gap generated among the loose joint, the screw cap and the sealing gasket of the loose joint mechanism, has good sealing performance and protects the sealing gasket.
Description
Technical field
The utility model relates to the valve accessories technical field, relates in particular to a kind of loose joint mechanism that is used for valve.
Background technique
Fig. 1 shows existing a kind of loose joint mechanism that is used for valve, this loose joint mechanism and valve 11 scyewed joint, comprise nut 21, tubulose union 22, be arranged on union 22 outer wall circlip 23 and at the gasket seal 24 of union 22 end faces.Nut 21 inside have internal thread 211, and its upper end portion has the inner convex platform 212 that protrudes to inside.Circlip 23 is arranged between gasket seal 24 and the boss 212, thereby makes that union 22 and nut 21 can relative moving around and union 22 can not spin off from inner convex platform 212 ends of nut 21.One end of union 22 and valve 11 scyewed joint, the internal thread 211 of nut 21 connects with pipeline thread, and loose joint structure like this couples together valve and pipeline.Connect valve and the pipeline that is positioned at the different distance place by travelling nut 21 in union 22.There is the gap in being arranged so that between union 22, nut 21 and gasket seal 24 of circlip 23, and gasket seal 24 is easily by bursting, and the sealing of loose joint mechanism is poor.
Summary of the invention
The purpose of this utility model is to improve the sealing of loose joint mechanism.
To achieve these goals, the utility model proposes a kind of loose joint mechanism that is used for valve, comprise nut, union and gasket seal, nut have internal thread and the upper end portion to projecting inward inner convex platform, union is tubulose and has outside thread in the upper end portion, the underpart of union is in nut, and gasket seal is arranged in the nut and the lower end surface of the union that reclining, and union has the outer lug boss of outside protrusion in the underpart of nut.
The utility model forms with nut and gasket seal in the outer lug boss of union underpart and cooperates, and has eliminated the space that existing loose joint mechanism produces between union, nut and gasket seal, and good airproof performance has also been protected gasket seal.
Description of drawings
Fig. 1 has shown the existing loose joint structural scheme of mechanism that is installed on valve;
Fig. 2 is the sectional view of the utility model loose joint structure;
Fig. 3 has shown valve and loose joint mechanism sectional view mounted thereto;
Below in conjunction with accompanying drawing the utility model is described in detail.
Embodiment
Referring to Fig. 2, the loose joint mechanism that the utility model is used for valve comprises nut 3, union 4 and gasket seal 5.Nut 3 have internal thread 31 and the upper end portion, to projecting inward inner convex platform 32.Union 4 is roughly tubulose, and its underpart has the outer lug boss 42 of outside protrusion, and its upper end portion has outside thread 41 and inner hexagonal hole 43.The underpart of union 4 is in nut 3, and boss 42 forms contact matching with nut 3, has eliminated the space between boss 42 and the nut 3.Gasket seal 5 is close on the lower end surface that leans against union 4, has eliminated the space between gasket seal 5 and the union 4.Like this, improved the sealing of loose joint mechanism, and can bursting gasket seal 5.
Referring to Fig. 3, thereby the outside thread of union 41 is installed in loose joint mechanism on the valve with valve 9 scyewed joint.Being provided with of inner hexagonal hole 43 made things convenient for the employing instrument that union is installed on the valve.The internal thread 31 of nut 3 is used for connecting with pipeline thread.Loose joint mechanism couples together valve and pipeline like this.
Claims (2)
