摘要：PURPOSE:To obtain a stably usable diaphragm for a long duration for theregulation of fluid discharge by constructing the diaphragm of ceramics for improving thecorrosion-resistivity, the heat-resistivity, and the durability. CONSTITUTION:Diaphragm 1,for example, repeats deformation and restoration respectively in accordance with theincrease and the decrease of pressure in a pipe 2, and opens and closes a discharge-regulating pipe passage 3 for regulating the discharge of the fluid flowing through a fluidgate pipe passage 4. In this case, the diaphragm 1 is constructed of ceramics. Thisconstruction permits to improve the corrosion-resistivity, the heat-resistivity, and thedurability in the diaphragm 1 for stable using for a long duration.
