Detailed Description

Fig. 1 to 3 show that a novel valve sealing connecting flange is related to, including valve body 1 and pipeline 2, pipeline 2 is connected with mounting flange 4 with the equal welded connection in one side that valve body 1 is relative, is provided with flange 3 between two mounting flange 4 relative one side.

When using novel valve seal flange, at first put the position between valve body 1 and pipeline 2 with flange 3, make fastening screw 31's one end again run through jack 43, make trapezoidal cone embedding pipe 32 imbed the inside of second through-hole 41 simultaneously, wherein, trapezoidal cone embedding pipe 32 passes through trapezoidal taper rubber sleeve and annular binding face 42 close-fitting together, then all tighten up fastening nut 5 in six fastening screw 31's one end, make fastening nut 5 compress tightly flange 4 and flange 3 link together, the same reason, compress tightly pipeline 2 and flange 3 and link together, thereby can make valve body 1 and pipeline 2 mutual sealing connection through flange 3, moreover, the steam generator is simple in structure, can be convenient for install, better sealed effect has, wide application scope.

In the further scheme, the docking flange 3 is including fastening screw 31, trapezoidal cone embedded pipe 32, first through-hole 33, trapezoidal cone embedded pipe 32 sets up on the position of 3 both sides of docking flange, and trapezoidal cone embedded

pipe

32 and 3 welded connection of docking flange, fastening

screw

31 and 3 through connections of docking flange, and fastening screw 31 is six that the border position for being close to 3 border positions of docking flange circularizes the distribution, trapezoidal cone embedded pipe 32, first through-hole 33 has been seted up jointly to the surface central axis position of docking flange 3, be convenient for the mounting of docking flange 3.

In a further scheme, the fixing flange 4 comprises a second through hole 41, an annular binding surface 42 and jacks 43, the second through hole 41 is arranged at the central axis position of the outer surface of the fixing flange 4, the annular binding surface 42 is arranged at the edge position of the second through hole 41, and the jacks 43 are six jacks annularly distributed at the edge position of the outer surface of the fixing flange 4, so that the rapid positioning and butt joint are facilitated.
