Three-dimensional four-way liquid pipe connector convenient to weld

Abstract

The invention provides a three-dimensional four-way liquid pipe connector convenient to weld. The three-dimensional four-way liquid pipe connector comprises a first connection pipe, a second connection pipe, a third connection pipe, a fourth connection pipe, elastic bodies and air connectors. The first connection pipe and the second connection pipe are located on the same central axis. The third connection pipe is perpendicular to the first connection pipe and the second connection pipe. The fourth connection pipe is perpendicular to the third connection pipe. The elastic bodies are arranged on the inner wall of the first connection pipe and the inner wall of the second connection pipe. The air connectors are movably connected with the elastic bodies. The third connection pipe is a welding connection pipe and is internally provided with a hollow cylinder, the inner wall of the hollow cylinder is provided with a plurality of curved surfaces, and a step is arranged at the junction of every two adjacent curved surfaces and provided with a plurality of closely-arranged raised lines. The three-dimensional four-way liquid pipe connector convenient to weld has the characteristics of being good in sealing performance, high in strength, low in welding difficulty coefficient and high in practicality.

Description

【Technical field】 [0001] The invention relates to the technical field of connectors, in particular to a three-dimensional four-way liquid pipe joint which is convenient for welding. 【Background technique】 [0002] The pipe joint is a connection tool between pipes and a detachable connection point between components and pipes. It plays an indispensable and important role in pipe fittings, and it is one of the two main components of hydraulic pipelines. The traditional pipe joints are simple in structure and can only perform a single connection function, and when connecting hydraulic pipes, it is easy to leak due to insufficient sealing of the connection, or the connection form is single, all of which are fastened or welded connections, which cannot meet the requirements of hydraulic pressure. There are many requirements for pipeline connection. [0003] At the same time, during the welding connection, due to the continuous vibration of the equipment during work, the welding...

Problems solved by technology

The traditional pipe joints are simple in structure and can only perform a single connection function, and when connecting hydraulic pipes, it is easy to leak due to insufficient sealing of the connection, or the connection form is single, all of which are fastened or welded connections, which cannot meet the requirements of hydraulic pressure. Various requirements for pipeline connection

[0003] At the same time, during the welding connection, due to the continuous vibration of the equipment during work, the welding surface is small or the welding surface is flat, so the welding is not firm, and the vibration of the equipment is easy to cause cracks between the pipes of the welded joint. The opening of the joint will cause the sealing of the joint to be damaged, and the liquid medium in the pipeline will flow out, causing pollution or waste
