Safety pressure vessel for engineering

The utility model relates to a safety type pressure vessel for engineering, which comprises a plurality of supports uniformly arranged on the bottom surface of the outer side of a pressure vessel mainbody, and universal wheels arranged at the bottom ends of the supports in a matching manner, the movable fixing assembly is fixedly connected with the outer side surface of the bracket through one end of a connecting inclined rod; the liquid inlet is formed in the upper surface of the pressure vessel main body and is communicated with the interior of the pressure vessel main body; and the sealingcover assembly is arranged at the top end of the liquid inlet. The pressure vessel fixing device has the advantages that the universal wheels are arranged at the bottom end of the pressure vessel sothat the pressure vessel can be pushed to be moved and transposed, and through the arrangement of the movable fixing assembly, switching between fixing and moving of the pressure vessel can be conveniently and rapidly achieved;
