Quick pipeline connecting structure and mounting and dismounting method

Abstract

The invention provides a quick pipeline connecting structure and a mounting and dismounting method, and belongs to the field of pipelines. The problem that existing pipeline connecting is low in strength and poor in sealing performance is solved. The quick pipeline connecting structure comprises an upper pipeline, a lower pipeline and a connecting device. The connecting device comprises an upper connecting component connected with the upper pipeline, and a lower connecting component connected with the lower pipeline. The upper connecting component comprises an upper quick connecting pipe, an upper connecting pipe and an upper connecting plate. The upper connecting component further comprises an upper fastener penetrating through the upper connecting pipe and the upper pipeline to be fixed.The lower connecting component comprises a lower quick connecting pipe, a lower connecting pipe and a lower connecting plate, and further comprises a lower fastener penetrating through the lower connecting pipe and the lower pipeline to be fixed. A circular-ring-shaped upper baffle ring is fixed to the outer wall of the bottom end of the upper quick connecting pipe coaxially. A circular-ring-shaped lower baffle ring is fixed to the inner wall of the top end of the lower quick connecting pipe coaxially. The quick pipeline connecting structure further comprises an adjusting pipe sleeving the outer side of the upper quick connecting pipe, the inner diameter of the upper quick connecting pipe is the same as the outer diameter of the lower quick connecting pipe, and a circular-ring-shaped sealing pad is fixed to the top end of the lower baffle ring. The connecting structure can be used for connecting pipelines in a high strength and high sealing performance manner.

Description

technical field [0001] The invention belongs to the technical field of pipelines, and relates to a quick connection structure of pipelines and an assembly and disassembly method thereof. Background technique [0002] When arranging drainage pipes in different areas, it is necessary to seal butt joint two drainage pipes, so connecting devices are widely used. Most of the current connecting devices are to fix the pipe fittings with glue, and then connect them through the thread on the connecting device. However, the strength of the glue is low after being fixed, and it is easy to be exploded by the impact of water flow, and the thread on the connecting device is used to match the butt connection speed. , not suitable for occasions that require quick assembly and disassembly. At the same time, in order to improve the connection strength between the connecting device and the pipe fittings, it is more suitable to use fasteners to connect, but the fasteners will pass through the p...

Problems solved by technology

Most of the current connecting devices are to fix the pipe fittings with glue, and then connect them through the thread on the connecting device. However, the strength of the glue is low after being fixed, and it is easy to be exploded by the impact of water flow, and the thread on the connecting device is used to match the butt connection speed. , not suitable for occasions that require quick assembly and disassembly. At the same time, in order to improve the connection strength between the connecting device and the pipe fittings, it is more suitable to use fasteners to connect, but the fasteners will pass through the pipes, so that the two ends of the fasteners are located on the inner and outer sides of the fluid. The fluid in the pipe fittings is easy to leak along the fasteners and through the connection parts of the fasteners. Therefore, the above-mentioned various solutions have some disadvantages to varying degrees, and the traditional connection device is more suitable for connecting circular pipes of the same specification. For different specifications and non-circular pipes, the connection ability is poor
