Abstract

The utility model relates to a low air resistance energy-saving bent tube, belonging to a pipeline interface piece. The central part of the bent tube is provided with a semi-spherical body with increased volume and a belly shape body, both ends are provided with interfaces which are connected with the pipeline, and the points of the bent tube body close to the two interfaces are of streamlined structures. The air resistance is reduced, the flow quantity is increased, and thus the power consumption can be avoided effectively, so as to achieve the goal of energy-saving. The utility model has the advantages of unique structure and easy fabrication, and can be widely matched with various pipelines.

Description

Low air resistace energy-saving bent tube

The utility model belongs to Pipe jointing part, can be widely used in range hood, refrigerating and air conditioning engineering, intake and exhaust airduct, the pipe arrangement of gas pipe, water pipe and fluid etc.

Existing tube bends part, its shape is identical with equipped with it pipeline, does not generally change, and is with the length lengthening of bend pipe at most, to reduce weld seam, falls low power consume.Yet only the function of improving bend pipe by the improvement of length is far from being enough; Windage in the pipeline can not reduce, and flow can not get increasing.If what flow in the pipeline is liquid, so, the not smooth situation that flows will appear, and especially when remote the conveying, flow velocity is slow, and the liquid rheology is little, and supply falls short of demand.Unexpectedly pipe is like this, and for a long time, this phenomenon must be less than change.

The purpose of this utility model is to improve the shape of bend pipe spare, to reduce windage, reduces noise, increases flow, and even saves the energy.

The technical solution of the utility model is implemented increasing the bend pipe volume, makes it become a half sphere shape or a tripe shape body.The bend pipe inside that is half sphere shape is designed to streamlined, when air-flow or liquid stream by bend pipe, this streamlined structure impels fluid to pass through bend pipe fast.

The utility model accompanying drawing is explained as follows:

Fig. 1 is the utility model front section view, and (1) is bent tubular body among the figure, and (2) are the bend pipe interface.

Below in conjunction with accompanying drawing the utility model is described in detail: bent tubular body among Fig. 1 (1) is half sphere shape or the tripe shape body that a volume increases, and itself and two interfaces (2) locate to be streamlined structure; When air-flow or liquid process bent tubular body (1), a large amount of fluids continuously are stored in the bent tubular body (1), flow away with main flow again then.Because bent tubular body (1) is a hemisphere, its volume increases, form a streamlined bend pipe single piece with two bend pipe interfaces (2), when fluid is flowed through herein, this streamlined structure is accelerated flow velocity, and flow increases, and resistance reduces, and can make windage be reduced to inferior limit, the wind song is eliminated by bend pipe.If a plurality of bend pipe series connection tippings can make horsepower reduce, reach energy-conservation purpose.The camber of this bend pipe can be 90 °, 45 ° or arbitrarily angled.

The utility model is through using, and its effect obviously is better than existing all types of bend pipe spare, its windage minimum, and the air quantity maximum, flow can increase 10%, than the power consumption of existing bend pipe spare saving more than 2.5%.And then because frictional resistance is little, Gu noise reduces therefore be highly advantageous to uptown environment maintenance and people's physical and mental health.

Claims

1, the energy-conservation bend pipe of a kind of low windage comprises two interfaces (2), it is characterized in that bent tubular body (1) is half sphere shape and the tripe shape body that a kind of volume increases, and is streamlined structure in bent tubular body (1) and two interfaces (2) part of joining.

2,, it is characterized in that the camber of bend pipe can be 90 °, 45 degree or arbitrarily angled according to the described low energy-conservation bend pipe of windage of claim 1.
