Ball valve body

The utility model relates to a ball valve body. Including valve body body, valve gap, valve gap flange and valve body flange, valve gap flange and valve body flange are flat round ring -shaped member, the import part of valve body body and valve gap is cylindricly, the entrance point of valve body body and valve gap all is equipped with the external screw thread, the hole of valve body flange and valve gap flange be equipped with respectively with outer thread to match's internal thread on the entrance point of valve body body and valve gap, valve gap flange and valve body flange through interior matching the external screw respectively with valve gap and this body coupling of valve body. Consequently, the inlet and outlet channel in valve body body and the valve gap goes up not seam, and the possibility of revealing only on the entrance point of valve body body and valve gap gets terminal surface and excircle, has been stopped to the seam, has prolonged life, also needn't carry out welding treatment in the a
