Abstract

The present invention provides a novel pipeline sectional bar and connectors thereof, which relates to a pipeline and a connecting mode thereof, and the present invention is particularly to used for the pipelines, such as various water pipes, air pipes, etc., and the connection thereof. The material of the novel pipeline sectional bar is inorganic glass fiber reinforced plastics; the internal and the external walls of two ports are provided with auxiliary sleeves of damping rings, and then, the sides of the auxiliary sleeves are sheathed with a rubber ring to be favorable for the connected sectional bar. No matter whether the connectors adopt the two-way connection, the three-way connection, or the corner connection, the connectors can be totally used. The connectors comprise a connecting pipe, a baffle ring, a valve sleeve, and a liquid feeding non-return valve. When the pipelines are connected, the ports of two pipelines are pairwise inserted into the connecting pipe until making the end surfaces of two water pipes collide. Thus, a loop of gaps are formed among the auxiliary sleeves of the pipelines, the baffle ring, and the connecting pipe, and the gaps can be called as gluing filling chambers. An adhesive is injected into the gluing filling chambers from the liquid feeding non-return valve, and after the adhesive is cooled, the connectors make two pipelines fixed together. The present invention has the characteristics of simple producing process, convenient and labor-saving construction of field assembly, and good sealing performance. The present invention is mainly used for the connection of living water supply pipes.

Description

New pipeline Shape and link

One, technical field

The present invention relates to a kind of pipeline profile and Placement thereof, in particular for pipeline and connections thereof such as all kinds of water pipes, airducts.

Two, background technique

Existing water pipe adopts iron pipe mostly, and it is embedded in underground or is laid on open-air experience and exposes to wind and rain, and the time one is long, and the phenomenon of corrosion just can take place, and shortens its working life.And the connection of various pipelines all adopts flange to connect, by the workmen more than on screw is screwed on, its time-consuming taking a lot of work bothers, and has pine to have tightly very much, connect like this between the pipeline of back and still have certain clearance, for water pipe, run off because the effect of hydraulic pressure can produce water body, and make external substance enter polluted water, if what carry is that domestic water will produce secondary pollution, be detrimental to health.

Three, summary of the invention

The objective of the invention is to provide a kind of pipeline profile and link thereof, makes it have that manufacturing process is simple, the assembled on site easy construction is laborsaving, the characteristics of good airproof performance, and it is mainly used in the connection of living water pipe.

Pipeline profile of the present invention comprises inorganic glass-fiber reinforced plastic pipeline, for ease of the connection of pipeline enclosure, adorns the auxiliary sleeve that inside and outside wall all has damped ring in its two-port, and overlaps a rubber band again on the auxiliary sleeve side; Auxiliary sleeve is made of centrifugally cast method when inorganic glass-fiber reinforced plastic pipeline is uncured.

Pipe joint of the present invention is that the connection at two logical, threeway or turning all can be used, and it comprises connecting tube, baffle ring, valve pocket and liquid feeding one-way valve, and a tapped hole is wherein arranged on the connecting tube, and its material also is a FRIM.

When producing assembling, two baffle rings are embedded the two ends of connecting tube respectively, after the liquid feeding one-way valve screws in the valve pocket, valve pocket is screwed in the tapped hole on the connecting tube again, like this, link has just been assembled and can be used for the connecting tube section bar.

During the connecting tube section bar, the port of two pipeline profiles to inserting in the connecting tube, until two pipeline profile end faces are collided, like this, is just made between the auxiliary sleeve of baffle ring, connecting tube and pipeline profile and forms a circle space, this space can be described as gummed and fills the chamber.Then adhesive being injected this gummed from the liquid feeding one-way valve fills in the chamber, because the effect of two ends baffle ring and rubber band, adhesive can not ooze out, filling up the back can not screw out this valve pocket before adhesive solidifies, with bolt tapped hole is sealed, after treating the adhesive cooling, link just is fixed together two pipeline profile butt joints.Adhesive can adopt plastic liquid or other glue class materials, as polyurethane liquid glue.

Link can also be installed rubber band at two ends and seal, and when adhesive injects, rubber band is flattened, and the big more sealing effect of pressure is good more, and owing to stopping of rubber band, liquid that can not overflows the outside.This moment, the port of outer connecting pipe can be blocked rubber band with a slice iron sheet.

The invention has the beneficial effects as follows: FRIM (FRIM) is to strengthen the inorganic composite materials that magnesium cement makes, intensity height, good corrosion resistance with glass fibre, after adopting this material conduit section bar and link thereof, just need not adorn flange on the pipeline, need not revolve bolt and nut, link is a pipe-like, it is simple to have manufacturing process, assembling and site operation simple labour-saving easy for installation characteristics connect curing back pipeline and are connected as a single entity the join strength height, good airproof performance, as be used for water pipe and can guarantee to carry water quality.

Five, embodiment

Embodiment's 1. present embodiment pipeline profile and links thereof, its structure can be seen from Fig. 1, pipeline profile comprises inorganic glass-fiber reinforced plastic pipeline 1, connection for ease of 1 of inorganic glass-fiber reinforced plastic pipeline, adorn the auxiliary sleeve 3 that inside and outside wall all has damped ring 3a in its two-port, overlap a rubber band 2 again on auxiliary sleeve 3 sides.Auxiliary sleeve 3 can be made of centrifugally cast method when inorganic glass-fiber reinforced plastic pipeline 1 is uncured, and the damped ring 3a of its inwall increases area of contact can make connection more firm.

Link is used in the connection of this pipeline profile, and it comprises connecting tube 7, baffle ring 4, valve pocket 5 and liquid feeding one-way valve 6, and a tapped hole 7a is wherein arranged on the connecting tube 7.Connecting tube 7 also can adopt the FRIM manufacturing.

When producing assembling, two baffle rings 4 are embedded the two ends of connecting tube 7 respectively, after liquid feeding one-way valve 6 screws in the valve pockets 5, valve pocket 5 is screwed in the tapped hole 7a on the connecting tube 7 again, like this, link has just been assembled and can be used for the connecting tube section bar.

During site operation connecting tube section bar, as shown in Figure 2, with the port of two pipeline profiles to inserting in the connecting tube 7, collide until making two pipeline profile end faces, like this, just make to form a circle space between the auxiliary sleeve 3 of baffle ring 4, connecting tube 7 and pipeline profile, this space can be described as gummed and fills chamber 8.Then adhesive being injected this gummed from liquid feeding one-way valve 6 fills in the chamber 8, because the effect of two ends baffle ring 4 and rubber band 2, adhesive can not ooze out, filling up the back can not screw out this valve pocket 5 before adhesive solidifies, with bolt 7b tapped hole 7a is sealed, after treating the adhesive cooling, link just is fixed together two pipeline profile butt joints.The area of contact that the damped ring 3a of auxiliary sleeve 3 outer walls has increased adhesive and inorganic glass-fiber reinforced plastic pipeline 1 makes being connected of pipeline profile firmer reliable.

Embodiment's 2. present embodiment pipeline profile and links thereof, its structure can be seen from Fig. 3, different is with embodiment 1 for it: it does not use baffle ring but extruding rubber band 10 is installed at the link two ends, its cross section can be the v font, when adhesive injects, rubber band is squeezed to both sides, closely cooperate with pipeline profile and link, the big more sealing effect of pressure is good more, and owing to stopping of rubber band, liquid that can not overflows the outside.The port of connecting tube 7 will be pushed rubber band 10 with a slice iron sheet 9 and block this moment.
