The pipeline plug valve for the chemical engineering comprises a valve body, the valve body comprises a valve shell, a plug cock is arranged in the valve shell, a side wall lining is arranged on the side wall of the plug cock, side pieces are arranged on the two sides of the side wall lining, screw rods are arranged on the other sides of the side pieces, and sliding blocks are arranged on the upper portions and the lower portions of the screw rods; a valve cover is arranged at the upper end of the valve shell, the upper end of the valve cover penetrates through the valve cover, a valve rod is fixedly connected to the middle of the upper end of the plug cock, an adjusting piece isarranged on the side wall of the valve rod and penetrates through the middle of the valve cover, the side wall of the adjusting piece is in threaded connection with the valve cover, and a bottom lining is arranged between the lower end of the plug cock and the valve shell; and a first sealing gasket is arranged at the upper end of the plug cock, and a pressing plate is arranged between the firstsealing gasket and the adjusting piece. Gaps between the plug cock and the side wall lining and between the bottom lining and the first sealing gasket can be adjusted through the adjusting piece and the screw rods.
Description
technical field [0001] The invention relates to the field of cock valves, in particular to a chemical pipeline cock valve. Background technique [0002] The plug valve is a closing member or a plunger-shaped rotary valve. By rotating 90 degrees, the channel port on the valve plug communicates with or separates from the channel port on the valve body to realize opening or closing. The shape of its valve plug can be cylindrical or conical. In cylindrical plugs, the passages are generally rectangular; in tapered plugs, the passages are trapezoidal. These shapes make the structure of the plug valve light. It is most suitable for cutting and connecting media and shunting, but it can also be used for throttling depending on the nature of the application and the erosion resistance of the sealing surface. [0003] After the liner of the existing plug valve is worn out, the liner needs to be replaced, which affects the transportation efficiency of the pipeline, and the maintenance...
