Abstract
The utility model relates to a balance elbow, which relates to a pipe component, wherein the elbow and a straight pipe are communicated at the same diameter and are fixedly connected into integration. The straight pipe is additionally provided with a corrugated pipe communicated with the straight pipe, and the straight pipe is fixed with a support bracket which is provided with a pulling rod. The utility model has the function of a common elbow. Because the arrangement of the corrugated pipe and the pulling rod, the utility model can balance inner pressure pushing force and compensate the plane displacement caused by the heat deformation on the folding angle part of the pipeline and the frictional force from soil, and thus, influence to the pipeline after the direction change of supporting wires is reduced. The utility model is particularly suitable for the occasion that the construction space of the pipeline on a direction changing part is insufficient and a full fixing joint can not be arranged.
Description
Technical field:
The utility model relates to pipe fitting, particularly elbow.
Background technique:
Elbow is at pipeline knuckle place connecting tube, reach the effect that changes direction, direct-buried insulated pipe particularly, press thrust big in the elbow, and the compensation pipeline at the knuckle place because the in-plane displancement that causes of thermal distortion and the frictional force that comes from soil, influence to pipeline after the branch line change direction is big especially, and general now employing is provided with full fixed knot to be influenced to reduce, but just full fixed knot can't be set under break-in place construction space condition of limited.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of balance elbow is provided, and is rational in infrastructure, and balance internal pressure and external power reduce the influence to pipeline, long service life.
The technological scheme that the utility model is adopted for achieving the above object is: the balance elbow, elbow communicates with the footpath with straight tube, and fixedly connected being integral, and is equipped with bellows on the straight tube and is communicated with straight tube, is fixed with support on the straight tube, and pull bar is installed on the support.
The utility model not only has the function of common elbow, and because the existence of bellows and pull bar, have press in the balance thrust and compensation pipeline at the knuckle place because in-plane displancement that thermal distortion causes and the frictional force that comes from soil, reduced influence to pipeline after the branch line change direction, applied widely, be specially adapted to pipeline can't be provided with full fixed knot in break-in place construction space deficiency occasion.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
Balance elbow as shown in the figure, elbow 3 and steel straight tube 4 is with the footpath and communicate, and the relation line place is integrally welded, and straight-tube portion is equipped with two sections bellowss 1, is welded with support 5 on the straight tube, and pull bar 2 is installed on the support.Be used for pipeline and the occasion of full fixed knot can't be set in break-in place construction space deficiency, convenience quick for installation, and guarantee that network security, life-span are long.
