Abstract
The utility model provides a quick assembly pipe joint, which is mainly composed of a three-way pipe, a pressing nut, a sealing ring, and a sealing rubber ring. The three ends of the three-way pipe are provided with outer screws. An inner screw is arranged in the pressing nut. The sealing rubber ring and the sealing ring are both a frustum shape. The ends of the three-way pipe and the pressing nut are respectively provided with a frustum. The frustum parts of the sealing rubber ring and the sealing ring are respectively placed in the frustums of each end of the three-way pipe and the pressing nut. When installed, a straight pipe does not need tapping, so heavy filament plates does not need to be carried, and hemps or raw material bands are not used for winding; when the pressing nut is rotated, the three-way pipe and the straight pipe are not rotated, so the utility model eases labor strength, is convenient to operate, has high installing speed, and is especially suitable for the installations of various water pipelines, steam pipelines, and gas pipelines.
Description
The utility model relates to a kind of improved pipe coupling, particularly a kind of fast-assembling pipe coupling.Be applicable to the joint of various waterpipes, steam line, gas pipe line.
The joint of existing waterpipe, steam line, gas pipe line, when mounted, to manage earlier material as required descends, good tap on the pipe material with filament plate again, on pipe thread, be coated with enamel paint, be wrapped with flax silk or twine with raw meal belt, and then be equipped with straight joint, elbow or the threeway of attacking female thread, rotation pipe or joint assemble.For ease of operation, in position also need be equipped with loose joint.The erecting bed, it is very heavy to carry filament plate, and especially the pipe material is used filament plate tapping operation more difficult, and is needed cost plenty of time and labour force more in short-term.
Task of the present utility model provides a kind of improved pipe coupling, does not need tapping on pipe during installation, thereby also just need not carry heavy filament plate, but use set pipe coupling, and the pipe material is descended can install.It is simple to operate, installation rate is fast.
Task of the present utility model is finished in such a way: main by the plastics with good mechanical strength or metal three-way pipe and gland nut, seal ring made of plastic, the O-ring seal made from heat resistant rubber are formed.There is outside thread three terminations of three-way pipe, and gland nut has internal thread.In order to prevent the steam seepage, seal ring and O-ring seal are arranged at straight tube and three-way pipe joint.Two seal rings all have a frustum, in the gland nut and each termination of three-way pipe a frustum are arranged all, and the frustum of O-ring seal and seal ring partly places in the frustum of each termination of three-way pipe respectively and in the frustum of gland nut and locate.Rotatably compress nut during installation, straight tube does not rotate, and two seal rings are compressed, and the inner ring of two seal rings and straight tube outer wall are closely cooperated, the frustum of two seal rings closely cooperates with the frustum of three-way pipe and the frustum of gland nut respectively, and two-layer seal ring has played the effect of dual fail-safe to preventing seepage.Because straight tube does not rotate and only rotatably compresses nut, the pipe coupling of this fast-assembling also has the function of loose joint in the installation.
Fast-assembling pipe coupling of the present utility model does not need on-the-spot tapping, need not carry heavy filament plate, reduces labor intensity, and installation rate is fast, and is easy and simple to handle.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a kind of tee union erection drawing of the present utility model.
Fig. 2 is a ring structure view of the present utility model.
Among the figure:
The frustum ┈ (2) of straight tube ┈ (1) gland nut (7)

The breach ┈ (18) of frustum ┈ (17) seal ring (3) of seal ring (3)
With reference to Fig. 1 three-way pipe (11) a garden cylindrical cavity that is passed through mutually by two Cylinders and form is arranged, the endoporus (13) of each termination of three-way pipe (11) is bigger slightly than the external diameter of straight tube (1), have 60 ° of frustums (6) in the termination of each end, there is outside thread (14) each termination.O-ring seal (5) is made with rubber, and O-ring seal (5) is passed through mutually with cone table by Cylinder and forms, and its Cylinder external diameter is identical with the non-threaded part diameter of three-way pipe (11), and all is inversed taper platform.The frustum (16) of O-ring seal (5) places in the frustum (6) of each termination of three-way pipe (11).As shown in Figure 2, seal ring (3) is a taper type, and its tapering is 60 °, has breach (18) on the frustum (17) of seal ring (3).Seal ring (3) places on the garden styletable face (4) of O-ring seal (5).The inner chamber of gland nut (7) is passed through mutually with cone table by Cylinder and forms, and its inner chamber Cylinder partly has internal thread (15), and the frustum (2) of gland nut (7) all is positive frustum with seal ring (3).The tapering of the frustum (16) of the frustum (6) of each termination of three-way pipe (11), the frustum (17) of seal ring (3), O-ring seal (5), the frustum (2) of gland nut (7) is all identical.There is six roots of sensation stiffening rib (8) to compress the mechanical strength of a chain for binding criminals mother (7) with enhancing on the gland nut (7).The endoporus (9) of the termination endoporus (12) of gland nut (7), the endoporus (10) of seal ring (3), O-ring seal (5) is all bigger than the external diameter of straight tube (1).During installation straight tube (1) is penetrated in the endoporus (9) of the endoporus (10) of termination endoporus (12), seal ring (3) of gland nut (7) and O-ring seal (5), according to straight tube (1) length and the position that need adjust O-ring seal (5) and seal ring (3) up and down, but must guarantee that O-ring seal (5) is enclosed within on the straight tube (1) fully, and seal ring (3) is right after with O-ring seal (5).The straight tube (1) that to put on gland nut (7), seal ring (3), O-ring seal (5) inserts an end endoporus (13) of three-way pipe (11), rotatably compress nut (7) it is connected with the outside thread (14) of three-way pipe (11) one terminations, till the end with seal ring (3), O-ring seal (5) and straight tube (1) and three-way pipe (11) compresses the formation drive fit.Owing to have a breach (18) on the plasticity of O-ring seal (5) and the seal ring (3), rotatably compress nut (7) and can guarantee friction tight formation.Other two end of same three-way pipe (11) is also by this procedure operation.
During installation, straight tube (1) and three-way pipe (11) all do not rotate, and only rotatably compress nut (7), so the pipe coupling of this fast-assembling also has the function of loose joint.
Embodiment 2: with the tee union principle, can design and produce into straight joint and elbow, the also same tee union of programmed sequence of operations.
