Abstract

The utility model relates to a pipeline and particularly discloses a pipeline with low probability of fouling. The pipeline is provided with a pipeline body and is characterized in that the radial cross section of the outer edge of the pipeline body is circular, and the radial cross section of a pipe hole of the pipeline body takes the shape of an egg with the radius of the upper part hole larger than that of the lower part hole. The pipeline provided by the utility model mainly solves the technical problems in the conventional tubular products for conveying flow body (or water) that both the inner and the outer of the radial cross section of a flow channel are regular circular, dirt and impurities in the fluid body (or water) are adhered on the inner wall of the pipeline and sedimented in the pipeline, and can effectively solve the difficult problem that the pipeline is fouled during the use, so that the service life of the pipeline is prolonged, the circulation capacity of the pipeline is improved, and the contamination degree of the flow body (or water) is reduced.

Description

A kind of less scaling pipeline

Technical field

The utility model relates to pipeline, particularly a kind of less scaling pipeline.

Background technique

Be rule circle shape inside and outside its runner radial cross section of tubing of now using fluid (or water) to carry, in fact in the fluid (or water) impurity is arranged more or less, these impurity can attachedly be bonded at inner tube wall and in pipeline under the deposition, time one is long, the impurity of piling up gets more and more and is difficult to and cleans, so not only have a strong impact on the conveying capacity of pipeline, and the impurity of piling up is sheltered evil people and countenance evil practices severe contamination fluid (or water).

The model utility content

The purpose of this utility model is to provide a kind of less scaling pipeline, be rule circle shape inside and outside mainly solving its runner radial cross section of tubing that has fluid (or water) conveying now, dirt in the fluid (or water), impurity can attachedly be bonded at inner tube wall and the technical problem under the deposition in pipeline, it can solve the pipeline dirty difficult problem of knot (heap) in use effectively, prolonged the working life of pipeline, improved the negotiability of pipeline and reduced the contaminated degree of fluid (or water).

For achieving the above object, the utility model is to realize like this.

A kind of less scaling pipeline, it has pipe body, it is characterized in that: the radial cross section of this pipe body outer rim is the circle shape, and the radial cross section of this pipe body pore is the egg shape of upper hole radius greater than the lower hole radius.

Described less scaling pipeline is characterized in that: the pore radius of the changeover portion between the upper and lower part of described egg shape pipe body pore is for progressively dwindling transition.

Described less scaling pipeline is characterized in that: described pipe body material is plastics, metal and nonmetal.

Described less scaling pipeline is characterized in that: described pipe body structure is single layer structure or various lamination layer structure.

The utility model compared with prior art its advantage is as follows: (1) does not influence primary tube pipe Placement; (2) pore top is the long radius zone, the bottom is the minor radius zone, under the certain hydrodynamic pressure or flow condition, its flow rate of fluid of fluid cross-section zone of shrinking increases, it is little on the flow velocity of pore inner fluid shows as greatly, so, impurity is difficult in pipeline particularly lower area deposition and fouling in the pore, and impurity is by the fluid scouring of lower area high flow rate and take away; (3) to relate to product be not increase big investment and produce original realization on original pipeline production technology basis to present technique, can solve a difficult problem in the reality effectively, and good social benefit and economic benefit are arranged.

Description of drawings

Fig. 1 is the radial cross section schematic representation of the utility model product.

Embodiment

See also Fig. 1, the utility model discloses a kind of pipeline configuration.As shown in Figure 1: it has pipe body 2, the radial cross section of this pipe body outer rim 3 is the circle shape, the radial cross section of this pipe body pore 1 is the egg shape of upper hole radius greater than the lower hole radius, it is hole shape symmetry in the OO' both sides, pore upper hole radius R 2 is greater than the lower hole radius r, by pore both sides radius R 3, R4 ... RN connection transition (wherein: RN=R2, R3=r, RN〉... R4〉R3).The ratio of described pore radius R 2/r is in 1 ~ 10000 scope, and the outer surface of zone, described pipeline top and the bottom corresponding R2, r should have sign, is convenient to correct installation.

Described pipe body 2 materials and structure have contained the material and the structure of present existing inside and outside circular pipe, and for example: the pipe body material can be plastics, iron and steel, copper material, cement etc.; The pipe body material can have specific characteristics can, as fire-retardant, anti-low temperature etc.; The pipe body structure can individual layer or honeycomb interlayer, hollow sandwich, foaming interlayer etc.; The pipe body structure can be that multiple material is composited.

Being the preferred embodiment of this patent only in sum, is not to be used for limiting practical range of the present utility model, and the described equivalence of promptly all contents according to the utility model claim changes and modifies, and is technology category of the present utility model just all.
