Description

Pipeline joint device Technical Field The invention relates to the technical field of hydraulic equipment, in particular to a pipeline joint device. Background Fully mechanized coal mining is an important sign of modernization of coal mining technology, and a hydraulic support is key equipment of a fully mechanized coal mining face and relates to safety of the whole mine face. The pressure of the hydraulic support is provided by a hydraulic pump station and is transmitted into a hydraulic cylinder of the hydraulic support through a pipeline system. With the development trend of coal mine pipelines advancing towards high pressure and large flow, a working face often has a plurality of pipeline joints, the interfaces are numerous, and the leakage risk is increased. Therefore, convenient disassembly and assembly and reliable connection of the mining pipeline joint are important for guaranteeing safe production.
