Abstract

The utility model relates to a fusion welding socket connecting pipe, which comprises a fusion welding socket pipe (1), a chamfer (2) arranged on the inner side of the socket of the fusion welding socket pipe, and a blocking column (3) arranged on the root or appropriate depth of the inner ring of the pipe socket. The connecting pipe not only reduces the difficulty of fusion welding and welding requirements but also improves the welding quality and efficiency.

Description

The thermofusible spigot connection pipe fitting

Technical field

The utility model relates to a kind of thermofusible spigot connection pipe fitting, relates in particular to the joint in this thermofusible spigot connection pipe fitting.

Background technique

The spigot and socket type hot melt connects and claims that again hot melt socket, connection pipe fitting are the bellmouth pipe fitting of molding and forming, generally are used for the connection of the following pipeline of external diameter 160mm.

Its principle is with pipe end outer surface and bellmouth pipe fitting internal surface while heating and melting, will melt pipe end and insert bellmouth, fixes and cools off until interface.

For tubing, pipe fitting hot melt are connected, generally be to adopt following method in the prior art:

1) on bellmouth and socket, does suitable mark with slide calliper rule or pen, locate in order to welding;

2) measure and mark and draw the hot melt degree of depth with slide calliper rule or pen at pipe end;

3) weld of tubing and pipe fitting forms even flange.

As seen from Figure 1, among the figure: thermofusible spigot pipe fitting 10, tubing 20, welding flange 101.

But, in real work, be difficult to implement by the requirement of working specification because hot melt connects the difference of working environment and peopleware.For improving conduits fused quality and Security, be necessary the structure of pipe fitting is designed.

Summary of the invention

The utility model technical issues that need to address have provided a kind of thermofusible spigot connection pipe fitting, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: the thermofusible spigot pipe fitting; There are chamfering, pipe fitting bellmouth inner ring root or appropriate depth that the post of stopping is arranged in the bellmouth oral area inboard of described thermofusible spigot pipe fitting.

Compared with prior art, the beneficial effects of the utility model are: both reduced hot melt difficulty and welding requirement, improved welding quality and efficient again.

Description of drawings

Fig. 1 is a thermofusible spigot connection pipe fitting schematic representation in the prior art;

Fig. 2 is the utility model generalized section;

Fig. 3 is the utility model outer surface schematic representation;

Fig. 4 adopts the utility model connection pipe fitting schematic representation;

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

By Fig. 2, Fig. 3 as seen: the utility model comprises: thermofusible spigot pipe fitting 1; There are chamfering 2, pipe fitting bellmouth inner ring root or appropriate depth that the post of stopping 3 is arranged in the bellmouth oral area inboard of described thermofusible spigot pipe fitting 1;

In described thermofusible spigot pipe fitting 1, there are the circular production time sign 4 and relative two sides of outer surface of pipe fittings of convex outer surfaces that a positioning groove 5 respectively is set;

The slope length of described chamfering 2 is 15-45 ° for the 2-8mm angle.

Chamfering setting in the utility model: be provided with in pipe fitting bellmouth oral area inboard that the slope is long to be guaranteed the welding flange chamfering absorption of tubing and pipe fitting, and do not overflow pipe fitting bellmouth oral area for the 2-8mm angle is 15-45 ° a chamfering, help construction progress and attractive in appearance;

Stop the post setting: at pipe fitting bellmouth inner ring root or appropriate depth the post that stops that one floor height is 1-5mm is set, has guaranteed the welding degree of depth of tubing and pipe fitting, improved welding quality and efficient;

Production time is provided with: at outer surface of pipe fittings a circular production time index gauge of projection is set, has guaranteed the trackability that pipe fitting is produced, help the follow-up of quality of pipe fitting;

The welding location is provided with: in outer relative two sides of pipe fitting a positioning groove is set respectively, has guaranteed the welding location of tubing and pipe fitting, improved welding quality and efficient.

As seen from Figure 4, among the figure: thermofusible spigot pipe fitting 1, tubing 20, welding flange 102.
