CN2487937Y - Pipe jointing device - Google Patents

Abstract

The utility model provides a pipe jointing device for mounting pipes which comprises a left pipe tooth tray(1) and a right pipe tooth tray (2) of which both inner surfaces and outer surfaces are respectively agnail surfaces and circular conical surfaces and which both are provided with openings, a lock sleeve(3) of which one end is a convex platform and an inner surface is a circular conical surface and which is encased in the right pipe tooth tray (2), a screw thread lock sleeve(4) of which an outer surface is a screw thread surface and an inner surface is a circular conical surface and which is encased in the left pipe tooth tray (1), a lock nut(5) of which one end with a convex platform is encased in the lock sleeve(3) and the other end with internal thread is screwed on the screw thread lock sleeve(4) and toroidal rubber sealing rings matching with the pipe jointing device. The utility model is characterized by saving man hour, lowering labor intensity and increasing mounting quality; moreover, the pipes can be conveniently maintained and repaired; as a result, the utility model is particular suitable for pipe maintenance.

Description

Pipe jointer

The utility model relates to the connection set that a kind of pipe laying is used.

In the installation of present various running water pipe, steam and gas pipe line, generally adopt external or union connects two tubes.This method need need connected two tubes hank knotting to twine raw meal belt or flax silk on screw thread, and need make big strength tighten joint.The not only time-consuming but also effort of this method often can not guarantee installation quality again, often leaks air to leak and need do over again.Especially pipeline maintenance is difficult for, and when the somewhere pipeline leaks vapour and leaks because of long-term corrosion, often whole or several tubes will be pulled down from two adjacent unions, could change one section and newly manage, and is very loaded down with trivial details and require great effort.

The utility model purpose provides a kind of pipe jointer, accomplishes the pipeline ease of connection, and is time saving and energy saving, and particularly pipeline maintenance is convenient.

The purpose of this utility model be achieved in that do hangnail is arranged in two, outward for conical surface and the left and right pipe chain wheel of opening is arranged.Because the pipe chain wheel has opening, it is easy to be set on the connected two tubes of desire.One end has boss and interiorly is enclosed within on the right pipe chain wheel for the lock sleeve of conical surface, outer for flank of thread, interiorly manage on the chain wheel for the screw-threaded coupling cover of conical surface is enclosed within a left side, locking nut has an end of boss to be enclosed within on the lock sleeve, and a female end screws in screw-threaded coupling and puts.If be rotated in the forward locking nut, it will make right pipe chain wheel and left side pipe chain wheel be adjacent to and bite two connected pipes of desire respectively by lock sleeve and screw-threaded coupling cover, spur two tubes displacement in opposite directions simultaneously, compress the ring-like rubber seal between two tubes, guarantee that the two tubes joint is water-tight or air tight.

The utility model is particularly suitable for pipeline maintenance work.When finding somewhere pipe leakage gas leakage, should locate pipeline and cut.According to the length of institute's cutting pipeline, change the pipeline of replacement, two ends are loaded onto pipe jointer respectively and are got final product, and again do not need to pull down the pipeline of very long distance, more do not need to go the hinge silk with wasting time and energy.

Compared with the prior art, characteristics of the present utility model are to save man-hour, reduce labor intensity, improve installation quality, and the maintenance pipeline is convenient.

Describe concrete structure of the present utility model in detail below in conjunction with drawings and Examples.

Fig. 1 is a pipe jointer master sectional view

Fig. 2 is that the A of Fig. 1 is to sectional view

As shown in the figure, in for the hangnail face, outward for conical surface and there is the left side pipe chain wheel 1 of opening to be enclosed within on the pipe, right side pipe chain wheel 2 with spline structure is enclosed within on another root pipe, one end has boss and interiorly is enclosed within on the right pipe chain wheel 2 for the lock sleeve 3 of conical surface, outer is that flank of thread, interior screw-threaded coupling cover 4 for conical surface are enclosed within on the pipe chain wheel 1 of a left side, locking nut 5 has an end of boss to be enclosed within on the lock sleeve 3, a female end screws on screw-threaded coupling cover 4, and other has the ring-like rubber seal 6 that is clipped between the two tubes supporting with it.

Claims (1)

1, the pipe jointer used of a kind of pipe laying, be the hangnail face in it is characterized in that having, outer is conical surface and left side pipe chain wheel (1) that opening is arranged and right pipe chain wheel (2), one end has boss and interiorly is enclosed within on the right pipe chain wheel (2) for the lock sleeve of conical surface (3), outer for flank of thread, interiorly manage on the chain wheel (1) for the screw-threaded coupling cover (4) of conical surface is enclosed within a left side, locking nut (5) has an end of boss to be enclosed within on the lock sleeve (3), a female end screws on screw-threaded coupling cover (4), and other has ring-like rubber seal (6) supporting with it.
