Technical Field
[0001] The utility model relates to the technical field of corrugated pipes, in particular to a corrugated pipe with enhanced pressure resistance. Background Art
[0002] The corrugated pipe is a thermally wound high-density polyethylene wound structured-wall pipe. This wall pipe uses high-density polyethylene resin as the main raw material and adopts a thermally wound forming process. It uses a polypropylene single-wall corrugated pipe as the support structure to make a special structured-wall pipe with high external pressure resistance.
[0003] When the existing corrugated pipes are buried and butt-jointed, only the butt-joint ends of the corrugated pipes are sleeved and butted for sealing, and the sealing ring around the butt-joint end can be squeezed for sealing to form a connection and cooperation between two groups of corrugated pipes. However, when the corrugated pipes are buried underground, the pipes are prone to deformation under extrusion, resulting in a certain gap or detachment between the pipe butt-joint ends, affecting the sealing effect. Therefore, we propose a corrugated pipe with enhanced pressure resistance. Summary of the Utility Model
[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a corrugated pipe with enhanced pressure resistance.
[0005] To achieve the above object, the utility model adopts the following technical scheme. A corrugated pipe with enhanced pressure resistance includes a pipe body. One end of the pipe body is integrally formed with a connection end, and the other end of the pipe body is integrally formed with a sealing sleeve end. A sealing gasket is sleeved outside the connection end. A packaging spiral groove is opened inside the sealing sleeve end. A packaging pad is connected to the periphery of the connection end. One end of the outer periphery of the pipe body is sleeved and installed with a fixed end, and the other end of the outer periphery of the pipe body is sleeved and installed with a butt-joint end. A connection screw groove is opened inside the fixed end, and a locking screw groove is opened inside the butt-joint end. A fixing bolt is threadedly connected in the connection screw groove.
[0006] Preferably, when every two groups of the pipe bodies are butt-joint installed, the sealing sleeve end at one end of the pipe body and the packaging pad around the connection end of the other end of the pipe body are in a spiral sleeved and packaged state through the packaging spiral groove, and one end of the sealing sleeve end and the sealing gasket around the connection end are in a secondary extrusion sealing state.
[0007] Preferably, the fixing bolt is in a threaded locking state through the connection screw groove inside the fixed end and the locking screw groove inside the butt-joint end.
[0008] Preferably, a flow guiding inner lining is installed at one end inside the pipe body. The flow guiding inner lining is an elliptical hollow structure. A support inner lining is installed at the other end inside the pipe body. An assembly groove is opened inside the support inner lining, and the assembly groove has the same structure as the flow guiding inner lining.
[0009] Preferably, when every two groups of the pipe bodies are butted against each other, the flow guiding inner lining at one end of the pipe body is in an assembled and clamped state in the assembly groove inside the support inner lining at the other end of the pipe body.
[0010] Preferably, a blocking groove is formed at one end of the support inner lining, and a plurality of groups of blocking kits are installed on the periphery of the flow guiding inner lining. The blocking kits on the periphery of the flow guiding inner lining are in a butted and blocked state in the blocking groove at one end of the support inner lining.
[0011] Preferably, an installation groove is formed inside the pipe body, a spring ring is embedded inside the installation groove, and a connecting piece elastically supported and cooperated with another spring ring is installed inside one of the spring rings. Both the spring ring and the connecting piece have deformation characteristics.
[0012] Beneficial effects
[0013] The utility model provides a reinforced pressure corrugated pipe, which has the following beneficial effects:
[0014] 1. For this reinforced pressure corrugated pipe, in this article, when every two groups of pipe bodies are butted and assembled, the sealing sleeve end at one end of the pipe body can be sleeved with the connecting end at one end of another group of pipe bodies. When the sealing sleeve end at one end of the pipe body is rotated, the encapsulation spiral groove inside the sealing sleeve end can be spirally sleeved and encapsulated with the encapsulation pad on the periphery of the connecting end, and is press-fitted and sealed through the encapsulation pad. At this time, the fixing bolt inside the connecting screw groove is rotated, and the threaded end of the fixing bolt is threadedly locked and connected with the locking screw groove inside the butting end. A sealing and locking fit is formed between the two groups of pipe bodies. In this way, after the two groups of pipe bodies are butted and sleeved, while ensuring the sealing effect, the connection stability between the two groups of pipe bodies can be increased, and the separation between the pipe bodies can be avoided, so as to improve the butt joint sealing effect between the pipe bodies.
[0015] 2. For this reinforced pressure corrugated pipe, after the two groups of pipe bodies are butted and installed, the flow guiding inner lining at one end of one group of pipe bodies will be inserted and assembled with the assembly groove inside the support inner lining in another group of pipe bodies, and multiple groups of blocking kits on the periphery of the flow guiding inner lining will be sequentially sealed and inserted into multiple groups of blocking grooves inside the support inner lining, forming multiple layers of blockades between the flow guiding inner lining and the support inner lining. When there is a conveying medium flowing inside the pipe body, the conveying medium can be directly introduced into another group of pipe bodies for conveying through the flow guiding inner lining, and multiple groups of blocking kits can form a sealing blockade at the butting end of the two groups of pipe bodies, so as to assist in improving the butt joint sealing effect of the pipe bodies.
