Description

Technical Field

[0001] The utility model belongs to the technical field of bellows, and in particular relates to a pressure-resistant bellows. Background Art

[0002] Bellows mainly include metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm boxes and metal hoses. Metal bellows are mainly used to compensate for pipeline thermal deformation, reduce shock, absorb pipeline settlement deformation, etc., and are widely used in petrochemical, instrumentation, aerospace and other industries.

[0003] The existing corrugated pipes have poor pressure resistance. When most of the corrugated pipes are buried underground, if heavy vehicles such as trucks pass by for a long time, the corrugated pipes may be distorted and deformed, which may lead to the breakage of the corrugated pipes, thus affecting their use. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a pressure-resistant corrugated pipe. Through the arrangement of triangular blocks and hexagonal prisms, the hexagonal prisms have strong pressure resistance. When the outer tube is squeezed, the hexagonal prisms can play a good pressure resistance effect. The triangular blocks are stable and play a supporting role between the inner tube and the outer tube. The strength of the raised thread is increased by the arrangement of the reinforcing ring. At the same time, the arrangement of the wire mesh increases the strength of the outer tube and reduces the probability of rupture when the outer tube is squeezed.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure-resistant corrugated pipe, comprising a fixed seat, an inner pipe and an outer pipe, the surface of the inner pipe is fixedly connected with a plurality of triangular blocks, the surface of the triangular blocks is fixedly connected with a reinforcement pad, the surfaces of the plurality of reinforcement pads are fixedly connected with an outer pipe, a plurality of hexagonal prisms are fixedly connected between the inner pipe and the outer pipe, the surface of the outer pipe is provided with a raised thread, the interior of the raised thread is provided with a reinforcement ring, and the interior of the outer pipe is provided with a wire mesh.

[0006] Furthermore, the plurality of hexagonal columns are respectively located between two reinforcement pads.

[0007] Furthermore, a fixing seat is provided on the surface of the outer tube, and both ends of the inner tube are respectively fixedly connected with sealing covers, and the sealing cover is fixedly connected to one end of the outer tube.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. Through the setting of triangular blocks and hexagonal prisms, the hexagonal prisms have strong compressive resistance. When the outer tube is squeezed, the hexagonal prisms can play a good compressive resistance effect. The triangular blocks are stable and play a supporting role between the inner tube and the outer tube. The strength of the raised thread is increased by the setting of the reinforcing ring. At the same time, the setting of the wire mesh increases the strength of the outer tube and reduces the probability of rupture when the outer tube is squeezed.

[0010] 2. The setting of the reinforcement pad enhances the fixing effect between the triangular block and the outer tube. The setting of the fixing seat can play a supporting role when the outer tube is placed or buried underground, thereby enhancing the stability of installation and placement.
