Abstract
PURPOSE: To accurately prevent accumulation of alien substances at the contacting water stopping part of the valve disk by providing a concave in the flow passage of the valve cage on the opposit side of the valve stem.
CONSTITUTION: At the side E where the valve stem 6 to move the valve disk 4 is, the axial direction contacting surface 18 of the elastic body 16 cntacts the valve seat part 19 of the valve cage 1 in circular condition, and on the other hand, at the opposit side F of the valve stem 6, no concave part is formed in the flow passage 2, and the radius direction contacting surface 20 of the elastic body 16 is contacted in circular condition so that the valve seat part and the flow passage 2 are flat without a division. In the middle range M between the E side where the valve stem 6 is provided and the F side on the opposit, the axial direction contacting surface 18 of the elastic body 16 gradually reduces, and instead, the radius direction contacting surface 18 and the radius direction contacting surface 20 are almost continuously alternated, and viewing from the axial direction, the whole peripheral range is accurately contacted with the inner peripheral surface of the flow passage 2 of the valve cage 1 or the valve seat part 19 to shut off the fluid.
