Abstract
The utility model discloses a double-channel fluid conveying pipeline, which can convey gas and light fluid, and includes an outer protective layer and two parallel pipe bodies arranged in the outer protective layer, and filler is arranged between the peripheries of the pipe bodies and the inner wall of the outer protective layer. The protective layer arranged outside the two pipe bodies ensure that the possibility of squeezing the pipe bodies is little; and by arranging the filler between the peripheries of the pipe bodies and the inner wall of the outer protective layer, when in use, the double-channel fluid conveying pipeline is not limited by the on-site conditions, the pipelines are prevented from being knotted or bent in case of winding or long-distance conveying, as a result, the normal conveying function of the pipeline is effectively ensured.
Description
Technical field
The utility model relates to fluid transmission equipment technical field, relates in particular to a kind of conveyance conduit.
Background technique
In fluid mechanics and HVAC technical field, existing Pitot tube is commonly single tube, when two conveyance conduits of needs; Usually adopt two single tube Pitot tubes, and existing Pitot tube is directly exposed outside, the using process middle tube body receives the restriction of condition; Be prone to be extruded, and two bodys are prone to coiling, hand over knot or bending when using together between the body; Cause pipeline obstructed, influence the normal conveying function of pipeline.
The model utility content
The utility model has overcome deficiency of the prior art; A kind of Twin channel fluid-transporting tubing is provided; This pipeline in use body does not receive the restriction of condition, be not extruded, and two bodys is when using together; Be difficult for coiling between the body, hand over knot or bending, can effectively ensure the normal conveying function of pipeline.
The technological scheme of the utility model is following:
A kind of Twin channel fluid-transporting tubing comprises external protection and is arranged on two bodys arranged side by side in the external protection, is provided with packing between the periphery of said body and the inwall of external protection.
Owing to be provided with protective layer in the outside of two bodys, be difficult for during use being extruded, be provided with packing between the periphery of body and the inwall of external protection; So in use; No matter do not receive limitation of field condition, be coiling, still long distances; Can not take place to hand over knot or bending between the pipeline, ensure the normal conveying function of pipeline effectively.
Said packing comprises two rubber bars arranged side by side, and the rubber bar is arranged between two bodys, makes the directly contact of two bodys, and is yielding when having avoided body directly to contact mutual extrusion, conveying function that can the better guarantee pipeline.
Said external protection is the PVC plastics, and the cross section of PVC plastics is circular; Described body is a pvc pipe, and the cross section of pvc pipe is circular.
Description of drawings
Fig. 1 is a Twin channel fluid-transporting tubing sectional view.
Wherein: 1 is external protection, and 2 is body, and 3 is packing, and 4 is the rubber bar.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
Like Fig. 1, a kind of Twin channel fluid-transporting tubing comprises external protection 1 and is arranged on two bodys arranged side by side 2 in the external protection 1, is provided with packing 3 between the inwall of the periphery of said two bodys 2 and external protection 1.
Owing to be provided with protective layer in the outside of two bodys 2, be difficult for during use being extruded, be provided with packing 3 between the inwall of the periphery of body 2 and external protection 1; So in use; No matter do not receive limitation of field condition, be coiling, still long distances; Can not take place to hand over knot or bending between the pipeline, ensure the normal conveying function of pipeline effectively.
Said packing 3 comprises two rubber bars 4 arranged side by side, and rubber bar 4 is arranged between two bodys 2, makes the directly contact of two bodys, and is yielding when having avoided body directly to contact mutual extrusion, conveying function that can the better guarantee pipeline.
Said packing 3 can be cellosilk, and resin etc. are soft, resilient material.
External protection 1 is PVC plastics or other protective materials, and the cross section of PVC plastics can be circle or other geometrical shapies.Body 2 is a pvc pipe, and the cross section of pvc pipe can be circle or other geometrical shapies.
Certainly, more than only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.Except that the foregoing description, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
