Technical Field

The invention relates to the field of pipeline equipment, in particular to a pipeline connecting pipe.

Background

The pipeline is an essential device for daily life, factory production operation and water source and energy transmission, is most commonly used for liquid and gas transmission and is mainly used for water supply, water drainage, heat supply, gas supply, long-distance transmission of petroleum and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. The pipeline is generally produced in a segmented mode, and when the pipeline is conveyed far away, a plurality of pipelines with different lengths and different thicknesses are required to be connected together through a connecting device; or when it is necessary to branch off the liquid/gas being transported, it is also necessary to connect the thinner branch pipes to the thicker main pipe. The existing commonly used pipeline connector is simple in structure, two ends of the connector are spiral pipe openings, and two pipelines are connected with threads at two ends of the connector respectively to complete butt joint of the pipelines. However, the existing pipe connection device still has the following disadvantages:

because the pipelines are various in types and the diameters of all the pipelines are different, when the pipelines are butted, if the sizes of the pipeline connecting device and the butted pipelines are not consistent, a new pipeline connecting device needs to be searched again, and great inconvenience is brought to the butting work.

Therefore, whether to produce a pipe connection device that can be used for pipes of various sizes is an urgent problem to be solved in the field of piping equipment.

The annular convex part has lower production difficulty, and the annular convex part can completely surround the pipeline, so that the pipeline has better leakage-proof effect.

Preferably, the cross section of the annular convex part is trapezoidal, the slope of one side of the annular convex part close to the pipe orifice is larger, and the slope of one side of the annular convex part far away from the pipe orifice is smaller, so that the resistance when the pipeline is inserted is lower, and the resistance when the pipeline slides outwards is larger, and the pipeline is better fixed in the connecting pipe.

Preferably, the pipe pad is in the shape of an incompletely closed ring, and one end of the pipe pad is provided with an uncovering part for conveniently detaching the pipe pad, so that the difficulty in detaching and installing the pipe pad is reduced.

Preferably, the large tube fixing part and the small tube fixing part are both provided with at least one injection hole for injecting the filler; the tube pad is also provided with at least one opening, and the opening of the tube pad is aligned with the injection hole. Thermoplastic or other waterproof materials can be injected through the injection holes to fill the gap between the pipeline and the pipeline connecting pipe, so that water leakage is avoided.

Preferably, the quantity of pipe pad is three, can dismantle the connection between every pipe pad, can be applicable to the butt joint of the pipeline of four kinds of sizes, can satisfy most of engineering requirements, is favorable to controlling manufacturing cost again, if the quantity of pipe pad is too much, then can greatly increased production degree of difficulty and manufacturing cost.
