Abstract

The utility model discloses an use novel pipe fitting of high -frequency induction welding mode construction, pipe fitting bell and spigot inner wall has inlayed the metal mesh through the hot melt adhesive to make the pipe fitting make the metal mesh generate heat under high -frequency induction welder's effect and melt the hot melt adhesive, thereby link up the tubular product pipe fitting is glutinous. This pipe fitting part makes the tubular product pipe fitting weld and becomes more convenient, can also be applicable to the welding of the tubular product pipe fitting of heavy -calibre winding pipe and so on simultaneously, and saving equipment input, reduces the cost of labor.

Description

A kind of novel pipe fitting using HFI welding mode to construct

Technical field

The utility model relates to a kind of novel pipe fitting using HFI welding mode to construct, and particularly relates to a kind of plastic pipe using HFI welding mode to construct.

Background technique

Plastic pipe is due to the performance of its excellence, be widely used in each field of municipal engineering, as engineering plumbing, energy heating system, gas pipeline system etc., but along with the progress of society and the raising of national life level, to the security of system of pipeline particularly pipeline connect in the requirement of combination property of tubing and pipe fitting day by day improve.In plastic pipe work progress, because the existing pipe fitting overwhelming majority is pure plastic pipe or electric melting pipe fittings, the sweat soldering of pure plastic pipe exist cannot ensure conversion time, socket joint dynamics and pipe part relative movement time the centering technical barrier that cannot ensure, be easy to occur the quality problems such as cold welding, rosin joint, particularly more than the tubing of 250 bores, not only will configure heavy sweat soldering instrument in sweat soldering construction, and welding quality 100% cannot to ensure; Although the welding of electric melting pipe fittings greatly reduces welding operation difficulty, but its fancy price, the hidden danger that pre-buried resistance wire exists open circuit and short circuit also can affect the selection of people and welding quality exists risk, and can not carry out the secondary welding of prosthetic and the pipe fitting that must more renew for the problems of welded quality that the later stage finds.For the cold welding in pipe fitting welding, rosin joint, constructing operation difficulty, engineering cost etc. systems engineering problem, not only how to ensure the Security of plastic duct system but also effectively can reduce construction and cost of material, be a difficult problem of pendulum in face of plastic duct system Production design construction industry.

Model utility content

The purpose of this utility model is to provide a kind of convenient welding, firmly, and is applicable to the plastic pipe of the employing HFI welding that heavy caliber pipe connects, and its way of realization is as follows.

The novel pipe fitting using HFI welding mode to construct, comprises pipe fitting body and pipe fitting joint socket, and described pipe fitting joint socket internal surface is equipped with wire netting.

The internal diameter of described pipe fitting joint socket is greater than the internal diameter of pipe fitting body.

Described wire netting surface is laid with the class binders such as hot melt adhesive.

The material of described wire netting is iron or stainless steel.

The beneficial effects of the utility model are.

(1) connection for small-bore common plastics pipe fitting uses the pipe fitting of HFI welding to connect tubing joint by adopting, not only operation can be reduced, can welding quality be guaranteed simultaneously, make the welding quality of weld homogeneous, the problem such as cold welding or rosin joint is less likely to occur.

(2) for the connection of the bigbore plastic tubes such as entwining tube, because its welding procedure is complicated, labor intensity is large, bigbore entwining tube is gone for by adopting the pipe fitting of HFI welding, only pipe part need be connected, radio-frequency induction coil is coated on joint, just can realize good melting and connect, thus, not only raise the efficiency but also cost of labor can be reduced preferably.

Accompanying drawing explanation

Fig. 1: pipe fitting sectional view.

Fig. 2: pipe part welding process sectional view.

In figure: 1 pipe fitting body; 2 pipe fitting joint socket; 3 wire nettings; 4 tubing; 5 high-frequency welders are wound around circle.

Specific embodiment

Use the novel pipe fitting that HFI welding mode is constructed, as Fig. 1, it comprises pipe fitting body 1, pipe fitting joint socket 2, wire netting 3.

This pipe fitting is the tubular structure of vertical symmetry, pipe fitting body 1 internal surface inwardly thickens, thus make pipe fitting body 1 internal diameter be less than the internal diameter of pipe fitting joint socket 2, its objective is that the internal diameter of tubing is identical with the internal diameter of pipe fitting body 1 in order to make pipe fitting joint socket 2 after the tubing of dimension inserts.Pipe fitting joint socket 2 internal surface is equipped with one deck ferrous metal net 3, and wire netting is fixed on pipe fitting joint socket internal surface by hot melt adhesive.

The welding process of this pipe fitting is as Fig. 2, tubing 4 port is inserted into pipe fitting joint socket 2 interior till it is propped up by pipe fitting body 1, the winding around 5 of high frequency induction welder is wound around a circle at the outer pen of pipe fitting joint socket 2, energising makes high frequency induction welder carry out work, pipe fitting joint socket 2 inwall ferrous metal net 3 generate heat under the effect of the winding around of high frequency welding, the hot melt adhesive of periphery is melted, pipe fitting joint socket 2 and tubing 4 are sticked together, close high frequency induction welder power supply, take off high frequency induction welder winding around, cool welding part, operation completes.

The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model specification and accompanying drawing content thereof to do equivalent structure or equivalence transformation; or direct or indirect other association areas used beyond the utility model, all can be considered in scope of patent protection of the present utility model.
