Abstract

A negative pressure resistant rubber pipe with a novel structure comprises a rubber pipe, wherein a plurality of reinforcing ribs are arranged on the outer surface of the rubber pipe which is a corrugated pipe. The reinforcing ribs are arranged on a protruding portion on the outer surface of the rubber pipe. By means of the plurality of rubber reinforcing ribs arranged on the outer surface of the rubber pipe, rigidness of the product is improved, and deformation under the negative pressure is reduced. The negative pressure resistant rubber pipe with the novel structure solves the problems of heavy weight, complex processing, low production efficiency, poor quality stability and the like of a pipe body of an existing negative pressure resistant rubber pipe wound by a steel wire. Without increasing thickness of the wall of the rubber pipe and adding wind of a plurality of layers of skeletons, the negative pressure resistant capacity of the rubber pipe can be guaranteed, the production technology is simple, the produced rubber pipe has attractive appearance and stable quality, and materials and cost are saved.

Description

The sebific duct of anti-negative pressure of new structure

Technical field

The utility model relates to a kind of sebific duct of anti-negative pressure of new structure, especially a kind of rubber corrugated pipe of anti-negative pressure of new structure or bend pipe.

Background technique

The existing sebific duct of anti-the negative pressure adopts inner one or more layers steel wire 1 that twines to strengthen body intensity (referring to accompanying drawing 1) more; Reach the requirement of work under condition of negative pressure; The defective of this structure is following: (1) is generally the circle cross section shape owing to strengthen the steel wire of body, and shape is wound on the body in the shape of a spiral, this negative pressure sebific duct; Its pipe internal surface is not level and smooth, and spiral helicine rill is arranged.Therefore, during with its conveyance fluid medium, the concavo-convex rill of pipe internal surface has just increased the resistance of fluid, not only influences efficiency of transmission, and jog also accumulates impurity easily; (2) under most of occasions; This sebific duct is work under the alternating stress effect that constantly changes, and causes the compression repeatedly or the dilatancy of tube wall easily, causes stability decreases, flattening or steel wire helix to destroy; In addition; Make the rubber and the framework layer that riddle between the steel wire helix produce serious shear deformation, this not only can quicken the destruction of rubber cover, and can cause the tube wall layering of flexible pipe; (3) mostly wire spirally-wound hose is straight tube, for requiring flexibly connecting of dog leg piping can't realize that using scope receives than limitations; (4) the sebific duct quality of steel wire winding is heavy, processed complex, and manufacturing efficiency is low, and cost is higher.

The model utility content

Consider the problems referred to above and accomplished the utility model; And a purpose of the utility model is to provide a kind of sebific duct of anti-negative pressure of new structure, and it has solved the existing sebific duct of anti-the negative pressure owing to using steel wire to twine the problem that the efficiency of transmission that causes is low, under the complex work environment, be easy to generate early stage damage such as distortion and tube wall layering.
