Beschreibung
Zusammenfassung:	The utility model relates to the technical field of valve castings, in particular to a composite valve casting which comprises a valve body, an installation hole is formed in the outer wall of the valve body, a magnet ring is installed on the inner wall of the installation hole, and a sealing rubber mat is installed at a port of the valve body. The magnet ring has a magnetic adsorption effect on the fixing plug pin, so that the fixing plug pin is better fixed to the inner wall of the mounting hole, meanwhile, the fixing plug pin is pulled out to disconnect the positioning hole and the mounting hole, the fixing shell only needs to be rotated to drive the threaded block, and the fixing plug pin is fixed to the inner wall of the mounting hole. The threaded block rotates on the inner wall of the threaded groove in a threaded mode, the threaded block rotates out of the threaded groove, the valve body and the fixed shell are disconnected, the fixed shell is convenient to open, the valve element is convenient to rep
