CN2165308Y - Practical fast connected pipe fitting - Google Patents

Abstract

The utility model relates to a pipe joint, which solves the problems of the rapid connecting pipes of time saving, labor saving, and material saving. The pipe joint is characterized in that a sealing sleeve on a connected pipe is sheathed on the inner hole of a locking nut; the cross-section of the sealing sleeve is in a rectangular ring; the front of the sealing sleeve is provided with a clamping ring which can be sheathed on the pipe which is connected; the cross-section of the clamping ring is a triangle and is provided with an entrance angle and an opening. One end of the inner through hole of the locking nut is provided with a taper angle for putting the clamping ring. The pipe joint can be applied to various pipes on high and low pressure pipelines, comprising elbows, three-way pipes, four-way pipes, reducer pipes, valves, etc.

Description

Practical fast connected pipe fitting

The utility model relates to pipe fitting joint.

The pipe fitting of outmoded routine connects, and always uses ways such as hitch, welding or gummed, not only takes material but also time-consuming, and construction and installation are inconvenience very, have the people once to design a kind of quick-acting pipe spare, but its structure is still simple inadequately, and the materials recruitment is still more.

The purpose of this utility model is to provide a kind of can satisfy the pipe fitting connection request, and the very simple practicality of structure tube connection piece fast.

The purpose of this utility model is achieved in that practical quickly jointed tubular workpieces, form by one group of locking nut, stuffing box gland and assemblying body, locking nut is the polygon nut of an end band tapering, in the middle of the assemblying body is through hole, the two ends inwall has the concave station shoulder, outer wall has the outside thread with the engagement of locking nut internal thread, and the stage casing is provided with polygonal boss; It is characterized in that being enclosed within the locking nut endoporus stuffing box gland of being taken on the material, its cross section is rectangular circle, be provided with before stuffing box gland and can be enclosed within the collar of being taken on the material, this collar cross section is triangle and has entrance angle and opening that locking nut inner via hole one end is provided with puts the taper angle that collar is used.

Above-mentioned design is altogether four kinds of parts, and as seen its structure is simple.

Further specify with drawings and Examples below.

Fig. 1 is the utility model structure and user mode schematic representation.

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

Fig. 3 is the B-B cross-sectional schematic of Fig. 1.

Fig. 4 is the C-C cross-sectional schematic of Fig. 1.

Fig. 5 is the utility model collar schematic representation.

Fig. 6 is Fig. 5 cross-sectional schematic.

Fig. 7 is the utility model stuffing box gland schematic representation.

Fig. 8 is Fig. 7 cross-sectional schematic.

Among the figure: 1 locking nut, 2 stuffing box glands, 3 collars, 4 assemblying bodys, 5 tubing, 6 polygonal boss, 7 outside threads, 8 concave stations shoulder, 9 internal threads, 10 entrance angles, 11 openings, 12 taper angles.

As shown in the figure: practical quickly jointed tubular workpieces, form by one group of locking nut 1, stuffing box gland 2, collar 3 and assemblying body 4, locking nut 1 is the polygon nut of an end band tapering, its inner via hole one end is provided with the taper angle 12 of putting collar 3 usefulness, for through hole two ends inwall concave station shoulder 8 is arranged in the middle of the assemblying body 4, outer wall has the outside thread 7 with internal thread 9 engagement of locking nut 1, the stage casing is provided with spanner with polygonal boss 6, be provided with collar 3 before being enclosed within the stuffing box gland of being taken on the material 52 in locking nut 1 endoporus, collar 3 cross sections are triangle and have entrance angle 10 and opening 11.

Locking nut 1, stuffing box gland 2, collar 3 are enclosed within on the tubing 5 together when installing and using, tubing 5 snaps in assemblying body 4 by concave station shoulder 8, tighten locking nut 1 then in the direction of arrows, this moment, stuffing box gland 2 compressive deformations played sealing and the fixedly effect of tubing 5, collar 3 makes the connection of tubing more solid and reliable because the squeezing action of stuffing box gland 2 makes the collar 3 that has the basil cut tube walls in locking, the utility model not only is used for the pipe butt joint, also can be used for elbow, threeway, four-way, reducer pipe, valve etc.Without hitch, save time fast without other annex installation and maintenance, be applicable to the connection of high low pressure pipeline, practical and convenient.

Claims (1)

1. Practical quickly jointed tubular workpieces is made up of one group of locking nut, stuffing box gland and assemblying body, and locking nut is the polygon nut of an end band tapering, in the middle of the assemblying body is through hole, the two ends inwall has the concave station shoulder, and outer wall has the outside thread with the engagement of locking nut internal thread, and the stage casing is provided with polygonal boss; It is characterized in that being enclosed within the locking nut endoporus stuffing box gland of being taken on the material, its cross section is rectangular circle, be provided with before stuffing box gland and can be enclosed within the collar of being taken on the material, this collar cross section is triangle and has entrance angle and opening that locking nut inner via hole one end is provided with puts the taper angle that collar is used.
