Description

an easy-to-connect pipe

technical field

The utility model relates to the technical field of pipelines, in particular to an easy-to-connect pipeline.

Background technique

Pipeline refers to a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles; usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it is discharged from the pipeline. The high-pressure part flows to the low-pressure part, and the pressure or gravity of the fluid itself can also be used to transport. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

Joining is an industrial term that refers to the process of joining two separate profiles or parts into one complex part or component with fasteners such as screws, bolts and rivets; commonly used mechanical fasteners are mainly bolts, screws and rivets.

The connection of pipes usually adopts threaded connection and flange connection. In order to ensure the tightness of pipe connection with large diameter, flange connection is usually used. However, the direct alignment between pipes makes it difficult to ensure the stability between pipes, resulting in relatively difficult connection. Difficult and inconvenient construction affects the efficiency of pipeline connection. At the same time, flange connection is directly used for the first pipeline and the second pipeline. If there are too few connections between pipelines, it is easy to cause water leakage and affect the connection effect.

For example, the patented notification number CN214197742U discloses a new type of easy-to-connect pipe for water conservancy engineering, which relates to the technical field of water conservancy engineering. , the first connecting seat and the second connecting seat, the bearing seat is a plate-shaped structure, the lower surface of the first connecting seat and the lower surface of the second connecting seat are welded to the upper surface of the bearing seat, the body structure includes the first pipe and the second pipe, The side surface of the first pipe is connected to the side surface of the first connection seat, the side surface of the second pipe is connected to the side surface of the second connection seat, the fixing structure includes a fixing ring, and the side surfaces of the two fixing rings are connected to the first connecting seat respectively. The surface on one side of the seat is connected to the surface on one side of the second connecting seat. The utility model relates to a new type of pipeline for water conservancy projects which is easy to connect. Vibration during the construction of water conservancy projects can be well reduced by arranging the cooperation between the shock-absorbing spring and the shock-absorbing column.

The connection of pipes usually adopts threaded connection and flange connection. In order to ensure the tightness of the pipe connection with larger pipe diameter, flange connection is usually used. Combining the above-mentioned existing technology, it is known that the pipes are directly aligned, and it is difficult to ensure the tightness between the pipes. The stability of the pipeline leads to difficulty in connection and inconvenience in construction, which affects the efficiency of pipeline connection. At the same time, flange connection is directly used for the first pipeline and the second pipeline. If there are too few connections between pipelines, it is easy to cause water leakage and affect the connection effect. , the problem is widespread and urgently needs to be improved.
