Abstract

The present invention relates to a kind of GRP pipe pipe fitting socket glue joint method using jacket type bellmouth to solve the deficiencies in the prior art, technical scheme is: use the jacket type bellmouth that the inner core being connected by one end and urceolus are formed with body, inner core external diameter is slightly less than socket internal diameter, urceolus internal diameter is slightly larger than socket external diameter, forms the semiclosed chuck that one end open is closed in one end between inner core and urceolus；During socket glue joint, first make the process of splicing face, then glue is placed in a circle bottom the blind end of chuck, then socket is slowly inserted from chuck openend, make glue be covered with splicing face along the Connexin between chuck and socket to external migration under the extruding of socket.Providing the benefit that: cementing position will not sandwich air and produces defect and adequately protected by inner core, strength of joint is high, and impervious antiseptic property is good, can be used for heavy caliber and corrosive fluid, easy enforcement simple to operate and material-saving saving of labor.

Description

A kind of GRP pipe pipe fitting socket glue joint method using jacket type bellmouth

Technical field

The present invention relates to a kind of GRP pipe pipe fitting socket glue joint method using jacket type bellmouth, belong to field of compound material.

Background technology

Traditional GRP pipe pipe fitting socket glue joint method is: use the bell bellmouth of fiberglass, first to the inwall of bell bellmouth and The outer wall of prefabricated socket carries out hacking and cleaning process, then with certain thickness, the glue preparing is uniformly coated on bellmouth inwall and inserts On the splicing face of mouth outer wall, then socket inserted bellmouth certain depth and keep static until glue hardens.The deficiency of above-mentioned way Part is: can sandwich a certain amount of air during band glue socket inserts band glue bellmouth and make cementing position existing defects, The problem that socket and bellmouth are opened then can occur owing to glue-joint strength is not enough sometimes, and the impermeability of cementing position is bad and Fail to be effectively protected, be generally used for small-bore and that corrosivity is little fluid.

Content of the invention

The problem existing for above-mentioned prior art, the present invention provides a kind of GRP pipe pipe fitting socket joint using jacket type bellmouth Adhering method, sandwiches air and forms defect, and make cementing position be effectively protected, improve the intensity of joint during to avoid grafting With impervious antiseptic property.

To achieve these goals, the technical solution used in the present invention is: use fiberglass jacketed formula bellmouth, and described jacket type holds Inner core and urceolus that mouth is each connected with body by one end form, and the external diameter of described inner core is slightly less than the internal diameter of respective socket, institute State the external diameter slightly larger than respective socket for the internal diameter of urceolus, thus between inner core and urceolus, form half envelope that one end open is closed in one end Close chuck；During socket glue joint, first hacking and cleaning process are carried out to the splicing face of inner tank theca and outer tube inner wall and socket inside and outside wall, Again a number of glue preparing is placed in a circle bottom the blind end of semiclosed chuck, then socket is delayed from chuck openend Slowly insert, make glue be covered with splicing face along the Connexin between chuck and socket to external migration under the extruding of socket, insert To certain degree of depth and keep static until glue hardening.

The invention has the beneficial effects as follows: 1) cementing position will not produce defect and be adequately protected by inner core because sandwiching air, joint Intensity is high, and impervious antiseptic property is good；2) can be used for heavy caliber and corrosive fluid；3) easy enforcement simple to operate, efficiency is high, Save material and artificial.

Brief description

Fig. 1 is the structural representation of a kind of fiberglass jacketed formula bellmouth according to example of the present invention.

Fig. 2 is a kind of GRP pipe pipe fitting socket glue joint method schematic diagram using jacket type bellmouth according to example of the present invention.

Label 1 in figure is body, and 2 is inner core, and 3 is urceolus, and 4 is socket, and 5 is glue.

Detailed description of the invention

The example of the present invention is described below in detail；The example describing below with reference to accompanying drawing is exemplary, is only used for explaining this Invention, and it is not intended that to invention restriction.

Turning next to Fig. 1, exemplified fiberglass jacketed formula bellmouth is made up of inner core 2 and urceolus 3 two-part structure, inner core 2 Being connected on same one end of body 1 with one end of urceolus 3, the external diameter of described inner core 2 is slightly less than the internal diameter of respective socket 4. The internal diameter of described urceolus 3 is slightly larger than the external diameter of respective socket 4, thus forms one end between inner core and urceolus and close a dististyle mouth Semiclosed chuck.

Turn next to Fig. 2, exemplified a kind of use jacket type bellmouth GRP pipe pipe fitting socket glue joint method be: first Hacking and cleaning process are carried out to the splicing face of the outer wall of inner core 2 and the inside and outside wall of the inwall of urceolus 3 and socket 4, then will be certain The glue 5 preparing of quantity is placed in a circle bottom the blind end of semiclosed chuck, then slowly inserts socket 4 from chuck openend Enter, make glue 5 be covered with splicing face along the Connexin between chuck and socket to external migration under the extruding of socket 4.

While there has been shown and described that the example of the present invention, it will be understood by those skilled in the art that: without departing from this Multiple change, modification, replacement and modification, the scope of the present invention can be carried out to these examples in the case of bright principle and objective Limited by claim and equivalent thereof.

Claims

1. a fiberglass jacketed formula bellmouth, is characterized in that: inner core and urceolus that jacket type bellmouth is each connected with body by one end form, The external diameter of inner core is slightly less than the internal diameter of respective socket, and the internal diameter of urceolus is slightly larger than the external diameter of respective socket, between inner core and urceolus Form one end and close the semiclosed chuck of one end open.

2. use a GRP pipe pipe fitting socket glue joint method for jacket type bellmouth, it is characterized in that: during socket glue joint, first make to glued joint Face process, then glue is placed in a circle bottom the blind end of semiclosed chuck, then socket is slowly inserted into from chuck openend, Glue is made to be covered with splicing face along the Connexin between chuck and socket to external migration under the extruding of socket.
