Embodiment 1

[0029] Such as figure 1 , figure 2 A PVC steel belt winding pipe is shown, which includes a steel belt winding belt 1, and the steel belt winding belt 1 includes an upper winding belt 11 and a lower winding belt 12; the upper winding belt 11 is internally provided with a steel belt 111 , the steel strip 111 includes an arc-shaped steel strip 1111 and an extended steel strip 1112, the two sides of the arc-shaped steel strip 1111 are respectively connected with an extended steel strip 1112; There are a plurality of support belts 2; the support belt 2 of the steel belt winding belt 1 forms a plurality of separate inner cavities, and an upper connection extension belt 3 is arranged on one side of the upper winding belt 11, and an upper connection extension belt 3 is arranged on the upper connection extension belt 3. There is an upper connection card head buckle tenon 4, and the other side of the upper winding belt 11 is provided with an upper connection card groove buckle tenon ...

Embodiment 2

[0033] This embodiment has been further improved on the basis of embodiment 1, as figure 1In the PVC steel belt winding pipe shown, the upper connection extension belt and the lower connection extension belt are both provided with sealing rubber strips.

Embodiment 3

[0035] This embodiment has been further improved on the basis of embodiment 2, such as figure 1 , figure 2 In the PVC steel belt winding pipe shown, the upper connection extension belt is provided with an O-shaped sealing strip, and the lower connection extension arm is provided with a Y-shaped sealing strip. This embodiment is a non-pressure self-flowing pipeline , the internal and external pressures are both atmospheric pressure, but under the action of water flow, the osmotic pressure of water is greater than atmospheric pressure, so the sealing ring of the inner rule adopts Y-shaped sealing strip, and the Y-shaped piece of the Y-shaped sealing strip is inside the water flow. Under the action of the seal, it is firmly attached to the sealed part. After the water pressure is decompressed by the Y-shaped sealing strip, the internal and external pressure is basically equal to the atmospheric pressure. At this time, under the elastic deformation of the O-shaped sealing strip, ...

Abstract

The invention discloses a PVC (polyvinyl chloride) steel belt winding pipe, which comprises a steel belt winding belt, an upper winding belt, a steel belt, a lower winding belt, a support belt, an upper connection extending belt, an upper connection clamp head, an upper connection clamp groove, a lower connection extension belt, a lower connection clamp head and a lower connection clamp groove. The PVC steel belt winding pipe has the beneficial effects that the PVC steel belt winding pipe covers the total advantages of a PE (poly ethylene) steel belt winding pipe and a PVC winding pipe; in addition, the production cost is greatly reduced; when the annular rigidity is high, the cost is low; the differences of the PVC steel belt winding belt cross section shape are used, after the bending deformation, the plate belt cross section shapes are different, the rebounding quantities are different, the rubber strip is automatically and tightly pressed through the different rebounding quantities, and the effect of water leakage prevention of the pipeline is achieved; the self-pressing type sealing rubber strip is formed. The PVC special glue water is not used; a product can be used after 24 hours from the production completion. The PVC steel belt winding pipe is applied to water introducing engineering of water works, and the water quality can completely meet the sanitation standard of life drinking water.

Description

technical field [0001] The invention relates to the field of pipe materials, in particular to a PVC steel strip winding pipe. Background technique [0002] Polyvinyl chloride resin is a non-toxic, odorless white powder with high chemical stability and good plasticity. It has excellent flame retardancy, wear resistance, chemical corrosion resistance, comprehensive mechanical properties, electrical insulation and other characteristics. Rigid polyvinyl chloride-PVC winding pipes are widely used in water diversion projects, irrigation water projects, sewage drainage projects, and rainwater drainage projects. In the water diversion project of the waterworks, the ordinary hard polyvinyl chloride-PVC winding pipe cannot meet the hygienic requirements of the project, because the ordinary hard polyvinyl chloride-PVC winding pipe uses hard polyvinyl chloride-PVC special glue, hard polyvinyl chloride Acetone, methyl ethyl ketone, perchlorethylene, trichloroethane, toluene and other o...
