摘要： A diaphragm valve having a diaphragm valve element including a valve element body movable into contact with a valve seat, a web portion extending outward from the valve element body, and a fixed portion formed at an outer peripheral edge of the web portion. The web portion includes a vertical portion vertically formed continuous with the valve element body, a horizontal portion horizontally formed continuous with the fixed portion, and a connecting portion of a circular arc shape (an upward protruding shape) in section to connect the vertical portion with the horizontal portion, thereby holding the vertical portion in constant contact with an outer surface of a backup.

摘要： The present invention is made to prevent stress concentration on or around a boundary between a valve element body and a web portion of a diaphragm even in controlling supply of high-pressure fluid, thereby improving durability of the diaphragm. A diaphragm valve 1 of the present invention comprises a diaphragm valve element 20 including a valve element body 21 movable into contact with a valve seat 13, a web portion 22 extending outward from the valve element body 21, and a fixed portion 23 formed at an outer peripheral edge of the web portion 22. The web portion 22 includes a vertical portion 22a vertically formed continuous with the valve element body 21, a horizontal portion 22c horizontally formed continuous with the fixed portion 23, and a connecting portion 22b of a circular arc shape (an upward protruding shape) in section to connect the vertical portion 22a with the horizontal portion 22c, thereby holding the vertical portion 22a in constant contact with an outer surface of a backup 40.
摘要翻译： 本发明即使在控制高压流体的供给时也能够防止阀体与隔膜的腹板部分之间的边界上的应力集中，从而提高隔膜的耐久性。 本发明的隔膜阀1包括一个隔膜阀元件20，该隔膜阀元件20包括可与阀座13相接触的阀元件主体21，从阀元件主体21向外延伸的腹板部分22以及形成在阀座21上的固定部分23。 腹板部分22的外周边缘。 腹板部22包括与阀体21连续地垂直形成的垂直部22a，与固定部23连续地水平形成的水平部22c和圆弧状的连接部22b（向上突出的形状 ）以将垂直部分22a与水平部分22c连接，从而将垂直部分22a保持与支撑件40的外表面恒定接触。
