Abstract

The utility model provides a high reliable fast installing pipeline joint which is composed of a pipe interface, a round elastic sealing sleeve, a fastening clamp ring and a pressing nut, wherein an annular plane is arranged on the pipe interface. When the pressing nut is screwed, the high reliable fast installing pipeline joint and the round section of a pipe extrude an elastic round ring parallel body of the round elastic sealing sleeve together to seal the round section of a pipe, and simultaneously an elastic cone of the round elastic sealing sleeve extrudes from a large-diameter part to a small-diameter part to seal the outer wall of the pipe. Two fastening round rings with notches are arranged on the fastening clamp ring. When the pressing nut is screwed, the notches are pressed in the pipe to make the pipe and a pipe fitting form shearing force for enhancing the connecting strength. When the pipe joint is connected with a pipe, the end head of the pipeline joint does not to be screwed. The utility model has the advantage of convenient and rapid instillation, and is suitable for various low pressure transmission systems.

Description

A kind of fast-assembling pipe coupling of high reliability
The utility model relates to a kind of fast-assembling pipe coupling of high reliability.
There are some problems in fast-assembling pipe coupling of the prior art on reliability, at first be the linking intensity problem, and its linking intensity is by friction, rather than shearing force, and under water hammering, pipe joint easily separates with pipe; A kind of collar internal cover type fast-assembling pipe coupling with lock proposes to solve the linking intensity problem with two dog wedges, because the cylindrical of its clamp ring is made up of cylinder and circular cone, its dog wedge can not all enter interior cover, the not basic linking intensity problem that solves.Secondly, the sealability of some fast-assembling pipe couplings is perfect inadequately, only takes seal approach at the tube wall place, and the place does not have seal approach at tube section, and the tube wall sealing is had relatively high expectations to the circularity of pipe and interface tube, has certain difficulty in actual applications.
The purpose of this utility model is: a kind of fast-assembling pipe coupling of high reliability is provided, uses this ready-packaged joint, not only do not need mantle fiber is carried out in the pipe termination, and solved the linking intensity and the sealing problem of fast-assembling pipe coupling.
The purpose of this utility model is achieved in that a kind of fast-assembling pipe coupling of high reliability, by interface tube, the close property circle of elasticity cover, snap in clamp ring, form with gland nut, the outer rounded head of interface tube has outside thread (4), interface tube the inner is conical (7), interface tube and pipe (1) jointing place, cross section is useful on the ring plane (9) of sealing, circular hole (13) is arranged in the middle of the elastic packing circle cover (8), its cylindrical is Elastic Circular cone (10), interior circle is circular (11), elastic packing circle cover (8) is elastic circular ring parallel body (12) with pipe (1) circular section interface, the outer side surface of elastic circular ring parallel body (12) parallels with the ring plane (9) of interface tube, snap in the clamp ring cylindrical and be conical (5), snap in the two track tape otch arranged in the clamp ring snap in annulus (6), snap in clamp ring and be provided with opening (14), gland nut has internal thread on (2), end face in the gland nut ascending pipe interface is circular cone stage body (3), and gland nut (2) is inserted in pipe (1), is inserted in and snaps in clamp ring, then put elastic packing circle cover (8), push interface tube, tighten gland nut, be combined into a kind of fast-assembling pipe coupling of high reliability.
Good effect of the present utility model is:
1, be useful on the ring plane of sealing on the interface tube, when gland nut is tightened, it and pipe
The elastic circular ring parallel body of circular section co-extrusion elastic packing circle cover forms the pipe circle is cut
The sealing of face.
2, the inner of interface tube is a cone, when gland nut is tightened, and the elasticity of elastic packing circle cover
Cone pushes to minor diameter part from large-diameter portion, forms the sealing to tube outer wall.
3, snap in the nicked annulus that snaps in of twice is arranged in the clamp ring, when gland nut is tightened, otch
Be pressed into pipe, make pipe and pipe fitting form shearing force.Strengthened linking intensity.
4, the installation process that connects with pipe fitting of pipe only needs hacksaw, spanner, does not need large-scale die head threading machine etc.
Instrument, and convenience quick for installation.
Further specify below in conjunction with embodiment and accompanying drawing:
Fig. 1 is installation connection figure of the present utility model.Fig. 2 is the sectional view of the utility model elastic packing circle cover, and Fig. 3 is the clamp ring view that snaps in of the present utility model.Referring to accompanying drawing.
Fig. 1 is this reality and novel installation connection figure, for simplicity, the lines of some reflection views have been omitted on the drawing, during installation, on pipe, be inserted in gland nut earlier, be inserted in again and snap in clamp ring, then be inserted in elastic packing circle cover, pipe is pushed interface tube, tighten gland nut, promptly finish the whole erection process.
The described pipe coupling of this model utility, the connection form of its joint is identical with former pipe coupling, i.e. elbow, threeway, reducer fitting etc.
The used material of the described pipe joint of this model utility can be used aluminum alloy, Cuprum alloy, zinc alloy, and also available plastic-aluminum, copper are moulded all composite materials.

Claims (1)
