Abstract
PURPOSE: To firmly fix valve seats by incorporatedly fitting by casting each valve seat when casting each valve body which has the valve seats of anticorrosive metal material on the inner peripheral surface of the valve cage and the outer peripheral surface of the valve body.
CONSTITUTION: When manufacturing a valve cage 12, first of all, a valve seat 10 of anticorrosive metal material such as stainless steel is provided almost at the middle in a space 24 of the valve cage mold between the upper and lower molds 22, 23 of a mold 21. That is; the top end side of a supporting rod 13... projected toward the direction of the center leaving the same distances between each other in the peripheral direction on the inner peripheral face of the valve seat 10 is inserted onto the peripheral side part to hold the valve seat 10. Then, by injecting hot water to separate from the mold after cooling and solidifying, the valve cage 12 in which the whole body of the valve seat 10 is casted can be taken out. Then, by cutting the appropriate surfaces of the valve seat 10 along the imaginary lines for the expected finishing measurement and cutting off the whole supporting rod 13, the valve cage can be completed. The valve body can be manufactured in almost the same process.
