Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The schematic diagram of the pipe joint of the present invention's fixing and sealing is simultaneously as shown in Fig. 1-Fig. 9, comprise jack shaft 1, fixed base 2, bolt 3 is tightly connected, black box 4, fastening gasket 5 and tightening nut 6, described jack shaft 1 is comprised of the first joint 7 and second joint 8 of dead in line, in described the first joint 7, be disposed radially the through hole 9 that is tightly connected, the side towards the second joint 8 of the described through hole 9 that is tightly connected is provided with the sealing groove 10 with the described through hole one that is tightly connected, described fixed base 2 inside are provided with the axis hole 15 matching with described the first joint 7 vertically, described the first joint 7 is through described axis hole 15, described fixed base 2 is enclosed within on described the first joint 7, described fixed base 2 inside are disposed radially the installation through hole 13 matching with the described through hole 9 that is tightly connected, described fixed base side is provided with the platform 14 concordant with the second joint 8 connecting parts with described the first joint 7, described black box is comprised of clamping plate 4-1 and gasket seal 4-2, described clamping plate 4-1 forms by the cylindrical part 16 matching with described installation through hole 13 with the corresponding connecting body 17 of described sealing groove 10, described gasket seal 4-2 is positioned at described clamping plate 4-1 inner side identical with described clamping plate shape, described black box is installed in described installation through hole 13, connecting body 17 on described clamping plate 4-1 and the described gasket seal part corresponding with described connecting body 17 all exposed the first joint 7 and fixed base 2 sides on described jack shaft 1, and connect by the described bolt 3 that is tightly connected, described the second joint 8 is threaded connection with described tightening nut 6, and described fastening gasket 5 is installed between described fixed base 2 and tightening nut 6.
