Abstract
The utility model discloses a bilayer pipeline tap which comprises two bilayer pipeline tap units, the inner pipe head faces of the two bilayer pipeline tap units are evenly jointed by mechanical sealing, the outer pipe of the two bilayer pipeline tap units are connected by radial airproof insert sealing. The utility model can completely separate two types of liquid from each other and the strike line of the pipeline does not need to be changed, promising that the lumens of liquid go the same way all along, achieving the goal of nicer efficiency of heat preservation, simplifying pipeline and lowering manufacturing cost.
Description
(1) technical field
The utility model relates to a kind of pipe joint, particularly a kind of Double layer pipeline joint.
(2) background technique
Be used for connecting the joint of double-layer heat insulation hydraulic pipe line at present, for solving the sealing problem of joint between two-layer tube chamber, adopt often the form of bypass will be wherein one road tube chamber draw, after escaping pipe joint, again introduce being back in the corresponding Double layer pipeline again, this just certainly will cause the liquid of insulation and insulation not go the same way, thereby reduces heat insulation effect, simultaneously also increase the pipeline coupling, improved cost.
(3) summary of the invention
The technical problems to be solved in the utility model is: a kind of Double layer pipeline joint is provided, makes it can guarantee that two kinds of different liquids tube chambers go the same way all the time, can separate fully again, and have good heat preservation effect.
In order to solve the problems of the technologies described above, the utility model comprises two bimetallic tube fittings bodies, and the inner tube face of described two bimetallic tube fittings bodies docks by end face seal, and the outer tube of two bimetallic tube fittings bodies is by the embedded connection of radial seal.
In full force and effect for the end face seal of pipe in making, the end face of the outer tube of described two bimetallic tube fittings bodies is gapped, and the outside of two outer tubes is provided with the connection clamp device.
The beneficial effects of the utility model are: the utility model can be fully with two kinds of different liquid separately, and do not need to change the trend of pipeline, guarantee that two kinds of different liquids tube chambers go the same way all the time, and can reach good heat insulation effect, simplify pipeline, the purpose that reduces cost.
(4) description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Wherein, 1, outer tube, 2, end face seal, 3, radial seal, 4, interior pipe.
(5) embodiment
A kind of specific embodiment as shown in Figure 1, comprise two bimetallic tube fittings bodies, interior pipe 4 end faces of two bimetallic tube fittings bodies are by end face seal 2 butt joints, and tube chamber separates fully with outer lumen in making, and the outer tube 1 of two bimetallic tube fittings bodies is by radial seal 3 embedded connections.The end face of the outer tube 1 of two bimetallic tube fittings bodies is gapped, and the outside of two outer tubes 1 is provided with the connection clamp device, connects clamp device and be the flange that is located on the outer tube 2 and the bolt and nut of adpting flange.
Claims (2)
1, a kind of Double layer pipeline joint, comprise two bimetallic tube fittings bodies, it is characterized in that: interior pipe (4) end face of described two bimetallic tube fittings bodies is by end face seal (2) butt joint, and the outer tube of two bimetallic tube fittings bodies (1) is by the embedded connection of radial seal (3).
2, Double layer pipeline joint according to claim 1 is characterized in that: the end face of the outer tube of described two bimetallic tube fittings bodies (1) is gapped, and the outside of two outer tubes (1) is provided with the connection clamp device.
