Description

Triple sealing connection structure for pipeline

Technical Field

The utility model relates to a pipe connection field, concretely relates to triple sealing connection structure of pipeline.

Background

A pipeline is a device for transporting a gas, a liquid or a fluid with solid particles, which is connected by pipes, pipe connections, valves, etc. The use of pipelines is very widespread, mainly in water supply, drainage, heating, gas supply, long-distance oil and gas delivery, agricultural irrigation, hydraulic engineering and various industrial installations. The joints of the pipelines are nodes in the pipelines, and the pipelines are connected by adopting a welding structure for ensuring the reliability and the sealing property of the pipelines. However, in practice, many pipelines need to be frequently disassembled for equipment maintenance, the pipelines connected by adopting a welding structure increase the operation difficulty, and the existing pipe connecting piece connecting structure has the defects of being not enough, or being troublesome to disassemble, or being poor in sealing performance.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, easy dismounting are swift, sealed effectual pipeline seal connection structure to solve the problem that exists in the above-mentioned background.

In order to achieve the purpose, the utility model provides a triple sealing connection structure of a pipeline, which comprises an upper pipe, a lower pipe, an upper pipe movable flange, a lower pipe movable flange, a sealing ring and a spring washer; an upper pipe movable flange matched with the outer wall of the pipe orifice of the upper pipe is sleeved on the outer wall of the upper pipe, and a lower pipe movable flange matched with the outer wall of the pipe orifice of the lower pipe is sleeved on the outer wall of the lower pipe; the upper pipe movable flange and the lower pipe movable flange are connected through a bolt to ensure the tight connection of the upper pipe and the lower pipe; the sealing rings comprise outer sealing rings, middle sealing rings and inner sealing rings, the sealing rings are arranged between the pipe orifice of the upper pipe and the pipe orifice of the lower pipe, the pipe orifice of the upper pipe is of a convex structure, and the pipe orifice of the lower pipe is of a concave structure; the spring washer is arranged between the upper pipe movable flange and the lower pipe movable flange.

Preferably, the axial surfaces of the upper pipe orifice and the lower pipe orifice are frosted surfaces.

The utility model has the advantages that: the upper pipe is matched with the lower pipe, and a bolt is combined to connect the movable flange for fixing, so that the structure is simple, and the disassembly and the assembly are convenient and quick; the movable flange is connected by the bolts to form pressure acting on the sealing ring to form triple sealing, so that the sealing effect is improved.
