Abstract
A heatable double-layer pipe fitting comprises a heating pipe and a fluid pipe sleeved with the heating pipe. The heating pipe is connected with the fluid pipe through rib plates. Wall thickness of the fluid pipe doubles that of the heating pipe. Distance of a gap between the heating pipe and the fluid pipe is 2/5 of semi-diameter of the fluid pipe. Thickness and width of the rib plates are equal to the wall thickness of the heating pipe. According to the arrangement, the heating pipe is additionally arranged outside the fluid pipe, and according to the needs, heating water or water vapor is fed into the gap between the heating pipe and the fluid pipe to heat the fluid in the pipe, thus flow velocity of the fluid in the pipe is guaranteed. The heatable double-layer pipe fitting is simple in structure, low in cost and effective in guaranteeing delivering speed of the thick liquid in the pipe.
Description
Technical field
The design relates to can heat double-deck pipe fitting, belongs to pipe fitting manufacturing technology field.
Background technique
In the transmission of thick liquid, due to the reduction of temperature, tend to reduce liquid in ducted flowing velocity, sometimes even produce and condense.Solution is to increase pumping plant now, gives liquid with power, and this solution is comparatively common in petroleum pipeline is carried.But this method, the one, increase conveying cost, the 2nd, in some liquid is carried, even if increase pumping plant, the change effect of flow velocity neither be too obvious.
Summary of the invention
For the deficiencies in the prior art, the design's object is to provide one can heat double-deck pipe fitting, at a heating pipe of the outside increase of fluid hose, in the gap of two pipes, logical upper heating water or water vapour, heat fluid in pipe, to ensure flow rate of liquid in pipe as required.
For achieving the above object, the design realizes by following technological means:
One can heat double-deck pipe fitting, it is characterized in that: comprise heating pipe and be enclosed within the fluid hose in heating pipe, between described heating pipe and fluid hose, passing through link of boards.
Preferred:
Described one can heat double-deck pipe fitting, it is characterized in that: the wall thickness of described fluid hose is greater than the wall thickness of heating pipe.
Described one can heat double-deck pipe fitting, it is characterized in that: the wall thickness of described fluid hose is the twice of heating pipe wall thickness.
Described one can heat double-deck pipe fitting, it is characterized in that: the radius of described fluid hose is greater than the gap between described heating pipe and fluid hose.
Described one can heat double-deck pipe fitting, it is characterized in that: the gap between described heating pipe and fluid hose is 2/5ths of fluid hose radius.
Described one can heat double-deck pipe fitting, it is characterized in that: the thickness of described gusset and width equal the wall thickness of heating pipe.
The invention has the beneficial effects as follows: the design is at a heating pipe of the outside increase of fluid hose, and in the gap of two pipes, logical upper heating water or water vapour, heat fluid in pipe, to ensure flow rate of liquid in pipe as required.The design is simple in structure, and cost is lower, can effectively ensure the transporting velocity of thick liquid in pipe.
Brief description of the drawings
Fig. 1 is the design's structural representation, the left view that Fig. 2 is Fig. 1.
The implication of drawing reference numeral is as follows: 1 heating pipe, 2 fluid hoses, 3 gussets.
Embodiment
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, 2, one can heat double-deck pipe fitting, it is characterized in that: comprise heating pipe 1 and be enclosed within the fluid hose 2 in heating pipe 1, between described heating pipe 1 and fluid hose 2, connecting by gusset 3.
According to the stickiness of fluid, can be chosen in logical heating water or water vapour between two pipes, and can select as required temperature.
Preferred:
Described one can heat double-deck pipe fitting, it is characterized in that: the wall thickness of described fluid hose 2 is greater than the wall thickness of heating pipe 1.
Meeting under the prerequisite of heating needs, can save material, reduce costs.
Described one can heat double-deck pipe fitting, it is characterized in that: the wall thickness of described fluid hose 2 is the twice of heating pipe 1 wall thickness.
Described one can heat double-deck pipe fitting, it is characterized in that: the radius of described fluid hose 2 is greater than the gap between described heating pipe 1 and fluid hose 2.
The liquid of fluid temperature suppression ratio tube hub that generally approaches tube wall is fast, for the object that place takies less and saves, can suitably reduce the temperature gap that adds between two pipes.
Described one can heat double-deck pipe fitting, it is characterized in that: the gap between described heating pipe 1 and fluid hose 2 is 2/5ths of fluid hose 2 radiuses.
Described one can heat double-deck pipe fitting, it is characterized in that: the thickness of described gusset 3 and width equal the wall thickness of heating pipe 1.
Gusset can not be blocked up or wide, otherwise, can affect and add flowing of hot fluid or gas, affect the efficiency of heating surface.
More than show and described the design's basic principle, major character and advantage.The technician of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described of describing in above-described embodiment and specification; do not departing under the prerequisite of the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
