Pipe joint

The pipe joint is connected with the tool between the pipeline and the pipeline, can be the connection point between components and hydraulic pipe fittings assembly and disassembly. As a significant role in the tube, it is one of the two main components of hydraulic pipeline.
The pipe joint has a wide range, a pipe joint used in general can be divided into two kinds of fittings and hydraulic hose and fittings joint hard tube. If in accordance with the connection pipe joint and pipe to points, hard tube joint with flared type, sleeve type and welding type three, hose connectors are mainly withhold hose joint.
Pipeline of hydraulic system and connection pipe joint are also different, the pipeline is screwed into the end is used in connecting thread. Taper thread by virtue of his vertebrae and the use of PTFE sealing screwing operation of material, is mainly used in low pressure in the hydraulic system. Fine tooth thread sealing effect is very good, is often used in high voltage system, but it requires the use of combination washer or O type ring against the end face of the enclosed work, sometimes use a copper washer, it is more suitable for the connection of pipeline wall is thick, the system consists of a joint body, connecting pipe and a nut. When in use, the joint body is embedded in the target, with the use of said in front of the washer will face seal, between the joint body and taken over by the rubber sealing, sometimes using spherical seal method.
The pipe joint can be connected component belongs to the disassembly assembly type, which in addition to meet the normal steady connection, sealing strong, reasonable size, small pressure loss, good process performance and so on requirements, must also meet the requirements of assembly and disassembly is convenient. Therefore, do not underestimate the small pipe joints, because only it exists to support the existence of the whole hydraulic system.
