Abstract

A stainless steel plastic compound pipe material connection device belonging to pipeline connection, which is mainly used in the mutual connection of the compound pipe material with the outer layer of stainless steel and the inner layer of plastic. The characteristics are that the device comprises a pipe component body with an inner stopping port table, an adhesive layer coated on the inner wall and used to bond the inner wall and the outer wall of the connected compound pipe material, a sealing loop arranged in the inner stopping port table, and an inner core sleeve inserted inside the loop and the compound pipe material. The utility model has advantages of simple structure, convenient installation and operation, and that the sealing loop generates double sealing through the transformation of the side surface under the intrusion of the inner core sleeve, then meets water to expand and automatically seal, thus the connection and sealing are all more reliable.

Description

Plastic stainless-steel composite-tubes material connection set
A kind of plastic stainless-steel composite-tubes material connection set belongs to the pipeline connection technology field.Be mainly used in the outer stainless steel that is, internal layer is the interconnecting of composite pipe of plastics, also can be used for being connected to each other between other forms of composite metal-plastic pipe, metal tube and the plastic tube.
In the prior art, cohering between traditional metal tube and the metal pipe element generally is to adopt the epoxies adhesive.Be characterized in and cohere at normal temperatures, but needed after cohering several hours even tens hours glutinous jails of ability curing; In a single day another characteristics are bond strength height, but are bonded together, then do not have way again and make them separately.Design at the beginning of the applicant 2000 and successfully also obtained No. 00213349.0 Patent right " thermosol coheres formula stainless steel sealed pipe fittings ", though can solve existing questions in the prior art, but being used for outer wall is stainless steel, inwall is that the composite pipe of plastics is when being connected with metal pipe element, often, pipe-line system is leaked because of factors such as method of construction, workmen's quality and tubing and pipe fitting matching gap be excessive produce poorly sealed phenomenon.
The purpose of this utility model is to provide a kind of structure very simple, and fitting operation is easy, and seal ring produces double seal by the side distortion under the inner core cover squeezing action, and the while is the self-sealing plastic stainless-steel composite-tubes material of water-swellable connection set again.
The basic principle that is tightly connected according to tubing and the characteristic of silicone rubber and hydro-expansive rubber composite material, basic design of the present utility model is: process an inner stopper platform in the suit place at pipe fitting mutually with the tubing that is connected, be pipe fitting from this to mouthful end with connected composite pipe mutually this section pipe fitting inwall of suit be coated with one deck and seal the binder that is bonded together in order to outer wall with pipe fitting inwall and composite pipe, a seal ring is installed at the stopping table place, inserts its other end and its integral body in the circle and can insert the interior inner core cover of composite pipe.Like this, tubing is cohered with pipe fitting mutually by binder, both can play seal action, can offset end thrust again, and seal ring by the side distortion, also makes tubing and pipe fitting produce the double seal effect under the squeezing action of inner core cover, thereby realizes purpose of design.
Plastic stainless-steel composite-tubes material connection set described in the utility model, by pipe fitting 1 be painted on its mouthpiece inwall in order to constitute with glue layer 3 that connected composite pipe 4 coheres mutually, it is characterized in that this installs its above-mentioned pipe fitting 1 and is provided with the inner stopper platform, this locates to be equipped with seal ring 2 and an end inserts in the sealing circle 2, the other end and the whole inner core cover 5 that inserts in the connected composite pipe 4 thereof.
The utility model has the advantages that: remove kept comprehensively that No. 00213349.0 patent had simple in structure, easy processing and fabricating, cost is low, fitting operation is easy, be connected firmly, in case find that poor sealing only need be heated to melting point again and promptly tubing be transferred to refitting, outside the advantage such as detachable, also because the pipe fitting of this device is processed with the inner stopper platform, quite cohere mutually by binder the outer wall of the inwall of one section long pipe fitting and connected composite pipe from this to port, both played seal action, can offset end thrust again, again because dress inner core cover in seal ring and the circle is equipped with at inner stopper platform place, under its squeezing action, be out of shape by the side, make tubing and pipe fitting produce double seal, sealing is tight more reliable, adds the composite structure that seal ring adopts silicone rubber and hydro-expansive rubber to be composited, promptly expand from motive sealing in case allow seal ring touch water, therefore make the sealing between pipe fitting and the tubing more firm.
Accompanying drawing is along axis complete section structural representation after one of the utility model most preferred embodiment installs on the connected composite pipe.
In conjunction with the accompanying drawings and most preferred embodiment, further describe structure characteristic of the present utility model as follows: with the pipe fitting 1 of stainless steel it by punch and weld and connected plastic stainless-steel composite-tubes material 4 each other mutually the root of that section pipe of suit be provided with the inner stopper platform, scribble to this section of port inwall with so that the glue layer 3 that wall coheres mutually outside wall and the connected composite pipe 4 within the pipe fitting 1 from this, the seal ring 2 that is composited by silicone rubber and hydro-expansive rubber is housed on the inner stopper platform, inserts the inner core covers 5 of a stainless steel in these circle 2 interior and connected composite pipes 4.
Change as present embodiment:
1, the material of pipe fitting and connected tubing all can change the composite material of other metals such as aluminium, aluminum alloy, steel, galvanized steel and they and plastics and plastics etc. into;
2, the material of inner core cover can be used engineering plastics instead.
