In each form of pipe joint, there are direct, right Angle, three-way and other types according to the number and direction of the joint path; The connection mode with the body is threaded connection, flange connection and so on. In addition, there are some fittings for special purposes.
The welded straight through pipe joint is mainly composed of joint body 4, nut 2 and nozzle L, and is sealed with o-ring 3 between the joint body and nozzle. When the joint body is screwed into the body, metal gasket or combined gasket 5 is used to seal the end face. Pipe nozzles and pipes in piping systems
Weld the connection. Welded pipe joints are firmly connected and reliably sealed. The shortcoming is that thick wall steel pipes are used and the welding workload is large because welding is required during assembly.
Clamp sleeve type pipe joint construction. This kind of pipe joint mainly includes three components: the joint body 4 with 24° conical hole, the clamping sleeve 2 with sharp inner edge, and the clamping nut 3 with pressing effect. When the nut 3 is tightened, the jacket 2 is pushed into the 24° cone hole, and deformed accordingly, so that the jacket and the cone inside the joint form a spherical contact seal; At the same time, the inner cutting edge of the sleeve is embedded in the outer wall of the tubing L, and an annular groove is pressed on the outer wall, thus playing a reliable sealing role. Sleeve type pipe joint has the advantages of simple structure, good performance, light weight, small volume, convenient use, no welding, steel pipe axial size requirements are not strict, and good vibration resistance, working pressure up to 31.5mpa, is an ideal pipeline connector in hydraulic system.
Cone seal welded pipe joint construction. This kind of pipe joint is mainly composed of joint body 2, nut 4 and pipe 5. In addition to the advantages of welded pipe joint, its O-ring is installed on the 24° cone of pipe 5, so that the sealing is possible to adjust and the sealing is more reliable. work
