Summary of the invention
The purpose of this utility model is to provide a kind of without revealing to overcome the deficiencies in the prior art, and simple process, difficulty of processing is little, the ball valve body structure that cost of production is low.
For achieving the above object, the utility model discloses a kind of ball valve body structure, comprise valve body body, valve gap, bonnet flange and valve flange, the side of valve gap and valve pocket is respectively equipped with the import and export with valve pocket UNICOM, described valve gap is fixedly connected with valve body body, the import and export of valve gap and valve pocket are provided with the valve seat shoulder rank for arranging valve seat near the one end at valve pocket center, described bonnet flange and valve flange are respectively equipped with access way, it is characterized in that: one end that described valve flange is connected with valve body body and one end outer wall that bonnet flange is connected with valve gap are provided with to dock takes on rank, the internal diameter of the import and export on the import and export of described valve pocket and valve gap respectively with described valve flange and bonnet flange are docked the external diameter takeing on rank and match, the docking shoulder rank of described valve flange and bonnet flange are equipped with respectively in the import and export in the import and export and valve gap of described valve pocket, described valve flange is connected the end face of one end and bonnet flange be connected one end end face with valve gap and flushes with the planar annular that valve seat takes on rank with valve body body, described valve flange and valve body body and bonnet flange and the connecting sewing place of valve gap on cylindrical are fixedly connected by welding.
The ball valve body structure that the utility model provides, one end outer wall be connected with valve gap by one end of being only connected with valve body body at described valve flange and bonnet flange is provided with to dock and takes on rank, and described bonnet flange and valve flange are connected one end end face with valve body body flushes with the planar annular that valve seat takes on rank, therefore not seam on the import and export passage in valve body body and valve gap, seam crossing is on the planar annular on valve seat shoulder rank, and the medium in valve and seam are isolated by tetrafluoro valve seat on valve seat shoulder rank under the effect of the pressure, stop the possibility revealed, seam crossing also need not carry out soldering simultaneously, simplify technique, difficulty of processing is little, reduce cost of production.
As further setting of the present utility model, the docking shoulder rank of described valve flange and bonnet flange are also provided with outside thread, also be provided with the internal thread matched with described outside thread in import and export on the import and export of described valve pocket and valve gap, described bonnet flange and valve flange are coordinated by internal and external threads and are connected with valve gap and valve body body respectively.More convenient like this assembling.
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.
