Abstract
The utility model relates to utilidor technical fields, specifically, being related to a kind of heat preservation pipe prefabricated foaming steering knuckle.Fastened and constituted by two half shell docking in " ┑ " shape, the half shell set there are two interface tube, the equal semicircular in shape in the section of two interface tube, and internal diameter is identical；The opening of two interface tubes of two half shells is symmetrical arranged there are two engaging lug, is equipped with connecting hole on each engaging lug；When two half shells are mutually butted fastening, two engaging lugs at corresponding position are mutually close in two half shells, and are locked by fastening bolt；Foam hole is reserved in one of half shell.The utility model both facilitates pipeline construction, time saving and energy saving, and is avoided that pipeline enclosure connection is not close and weeping occurs.
Description
Technical field
The utility model relates to utilidor technical fields, connect specifically, being related to the heat preservation pipe prefabricated foaming steering of one kind
Head.
Background technique
Insulating tube is the abbreviation of insulated piping, and insulating tube is used for the conveying of liquid, gas and other media, in petroleum, is changed
It is commonly used in the adiabatic heat-insulation engineering of the pipelines such as work, space flight, military affairs, central heating, central air-conditioning, municipal administration.
Current insulating tube majority construction is identical, is to be connected to one by multistage, a conveyance conduit is formed, in delivery pipe
When road needs to turn to, in the junction of two insulating tubes, usually the connecting pin of two insulating tubes is first soldered to one, then
Polyurethane and polyethylene are coated to complete to seal by outside, and still, such connection type is both not easy to pipeline construction, time-consuming to take
Power, and it be easy to cause pipeline enclosure connection not close, it is easy to appear weeping.
Utility model content
The purpose of the utility model is to provide a kind of heat preservation pipe prefabricated foaming steering knuckles, to solve above-mentioned technology
Problem.
To solve the above problems, the technical scheme adopted by the utility model is
A kind of heat preservation pipe prefabricated foaming steering knuckle, it is characterised in that: the steering knuckle is by two in the half of " ┑ " shape
Shell docking, which fastens, to be constituted, and the half shell is set there are two interface tube, the equal semicircular in shape in the section of two interface tube, and internal diameter
It is identical；The opening of two interface tubes of two half shells is symmetrical arranged there are two engaging lug, is equipped on each engaging lug
Connecting hole；When two half shells are mutually butted fastening, two engaging lugs at corresponding position are mutually close in two half shells, and
It is locked by fastening bolt；Foam hole is reserved in one of half shell.
Preferred: the foam hole is located at the centre of half shell.
The utility model has the advantages that compared with prior art, the connection construction that the utility model can be used for when conveyance conduit needs to turn to,
When construction, first by the internal layer core pipe of the identical insulating tube of two outer diameters by turning to after pipe connecting piece is linked together, then by two and half
Shell is wrapped in the outside of two insulating tube connecting pins, and after being locked by fastening bolt, the pipette tips of foam gun from
Foam hole is reached in reducer union and is foamed, and both facilitates pipeline construction, time saving and energy saving, and is avoided that pipeline enclosure connection not
Closely there is weeping.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Embodiment:
Referring to Fig.1, Fig. 2, heat preservation pipe prefabricated foaming steering knuckle described in the present embodiment are in the half-shell of " ┑ " shape by two
The docking of body 1, which fastens, to be constituted, and the half shell 1 is set there are two interface tube, the equal semicircular in shape in the section of two interface tube, and internal diameter
It is identical；The opening of two interface tubes of two half shells 1 is symmetrical arranged there are two engaging lug 2, is all provided on each engaging lug
There is connecting hole；When two half shells 1 are mutually butted fastening, two engaging lugs 2 at corresponding position are mutually tight in two half shells 1
Patch, and be locked by fastening bolt 3；Foam hole 4 is reserved in one of half shell.In the present embodiment, the foaming
Hole 4 is located at the centre of half shell 1, and it is more uniform to be conducive to foaming when construction.
When construction, after first the internal layer core pipe of the identical insulating tube of two outer diameters is linked together by steering pipe connecting piece, then
Two insulating tubes are carried out heat preservation airtight connection by the steering knuckle to be matched using the outer diameter with insulating tube, concrete operation method:
First by the internal layer core pipe of two insulating tubes by turning to after pipe connecting piece is connected as one, then by two half shells of steering knuckle
It is wrapped in the outside of two insulating tube connecting pins, and after being locked by fastening bolt 3, the pipette tips of foam gun are from foaming
Hole 4 reaches is foamed in direct-connected connector, both facilitates pipeline construction, time saving and energy saving, and is avoided that pipeline enclosure connection is not tight
It is close and weeping occur.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
Claims (2)
