Abstract
The utility model provides a coupling formula pipeline crimp connection device, including be used for with the pipe end interference fit's of two takeovers coupling to and be used for through two packing rings of sealed glue with the pipe end sealing connection of two takeovers. The utility model is suitable for a not needing welded connection's piping installation, adopting coupling and pipe end interference fit's mode, be connected to two pipes together, it is sealed gluey to have cohesiveness between the excircle of coupling middle part and pipe end tip, has the effect that can bear pressurization. This kind of connecting device not only had been applicable to the connection that needs the undercoating protection tube but also be applicable to compound pipe of inside lining and ordinary steel pipe, had avoided because the complicated problem of construction sum check that the welding of pipe end brought has the characteristics that high efficiency constructed again.
Description
Technical field
This utility model relates to the bindiny mechanism of pipeline, particularly relates to be applicable to have undercoating and composite bimetal pipe
Pipe end connect coupling type pipe pressuring connection attachment means.
Background technology
In the construction of undercoating anti-corrosion pipe, there is welding high temperature pipe end undercoating anticorrosion when pipe end connects
The problem of corrosion material.Even if the pipe end docking further for composite bimetal pipe uses special welding procedure, also
It is difficult to avoid that the problem of accelerated corrosion because the fusing of welding metal causes the reduction of metallicity.In order to prevent connecing
Anticorrosive coat at Kou is occurred by the problem of welding high temperature failure, uses the mode of coupling type plug-in mounting to carry out the company of pipe end
Connecing, pipe end does not has the impact of high temperature melting, can either ensure sealing effectiveness, can improve again speed of application.
Utility model content
The purpose of this utility model, it is simply that in order to solve the problems referred to above, it is provided that a kind of coupling type pipe pressuring connection connects dress
Put.
In order to achieve the above object, this utility model have employed techniques below scheme: a kind of coupling type pipe pressuring connection is even
Connection device, including:
For the box cupling with the pipe end interference fit of two adapters, the centre in box cupling is provided with interior step；
For two packing rings connected by the end sealing of fluid sealant and two adapters, two packing rings are separately positioned on
The both sides of step in box cupling.
Described packing ring is plane for the one side being connected with step in box cupling, for be connected with the end sealing of adapter
One side is concave-convex end face.
Described concave-convex end face includes that the circle step being arranged on end face outer ring is recessed with the profile of tooth being arranged on end face inner ring
Male structure, described step is concordant with the concave surface of profile of tooth concaveconvex structure.
This utility model is applicable to have undercoating and the connection of composite bimetal pipe pipe end, is also applied for common pipe
Quick connection.Pipe end ensures pipe by the effect of end sealing glue together with passing through to crimp link with the surface of box cupling
Road connection has the effect that can bear high pressure sealing, both can facilitate on-the-spot rapid construction, can avoid again because welding
The damage of anticorrosive metal function is affected by the metal molten high temperature caused.
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present utility model；
Fig. 2 is the structural representation of the box cupling in this utility model.
Fig. 3, Fig. 4 are the structural representation of the packing ring in this utility model.
Fig. 5 is when centre is without packing ring, carries out the schematic diagram of plug-in mounting by the way of clamp.
Detailed description of the invention
Seeing Fig. 1, Fig. 2, Fig. 3, Fig. 4, coupling type pipeline of the present utility model connects compression bonding apparatus, including using
In the box cupling 1 with pipe end 4 interference fit of two adapters, and for by fluid sealant 3 and the pipe of two adapters
Two packing rings 2 that end 4 is tightly connected.
Centre in box cupling is provided with interior step 11, and two packing rings 2 are separately positioned on the both sides of step in box cupling.
Above-mentioned packing ring 2 is plane for the one side being connected with step in box cupling, for being connected with the end sealing of adapter
One side be concave-convex end face.This concave-convex end face includes the circle step 21 being arranged on end face outer ring and is arranged on
The profile of tooth concaveconvex structure 22 of end face inner ring, step is concordant with the concave surface of profile of tooth concaveconvex structure.Profile of tooth concaveconvex structure 22
Cure shrinkage for fluid sealant.Step 21 is for the storage of too much fluid sealant.
Use state of the present utility model is as shown in Figure 1.For connecting the pipe end 4 of two pipelines.During connection,
Pipe end smears a certain amount of fluid sealant 3, by compression bonding apparatus by two pipe end press-in box cuplings, until pipe end and pad
Till the end contact of circle 2.
During as it is shown in figure 5, do not use packing ring in the middle of box cupling, fixture 5 can be used to carry out the location positioning of plug-in mounting,
Ensure that the link position of box cupling and two pipe ends is symmetrical.
Interference fit due to tube end outer surface Yu box cupling inner surface, it is achieved being reliably connected of two pipe ends, and pass through
The fluid sealant cementation of pipe end can realize the pressure bearing and seal of pipeline.
