Abstract: A pressure-reducing valve is provided in which a diaphragm rod connected to a valve body of a valve mechanism is connected to a central part of a diaphragm having its peripheral edge part clamped between a body and a diaphragm cover, wherein the diaphragm (28) is formed from a disk-shaped rubber sheet for which the sheet thickness of at least its peripheral edge part is uniform in the natural state, and in a state in which the diaphragm cover (17) is fixed to the body (16) so that the peripheral edge part of the diaphragm (28) is compressively held between a collar portion (17b) of the diaphragm cover (17) and a clamping face (91) of the body (16), a portion having, of the gap between the collar portion (17b) and the clamping face (91), a minimum gap is positioned further inward in the radial direction of the diaphragm (28) than a portion having a maximum gap. This enables the sealing properties and the pull-out resistance for the diaphragm to be guaranteed while achieving a reduction in weight and a reduction in cost.

Abstract translation: 本发明提供一种减压阀，其中，与阀机构的阀体连接的隔膜杆连接到隔膜的中心部分，隔膜的周缘部夹在主体和隔膜盖之间，其中隔膜（28） 由至少其周缘部的板厚在自然状态下均匀的圆盘状的橡胶片形成，并且在隔膜罩（17）固定于主体（16）的状态下， 隔膜（28）的周缘部被压缩保持在隔膜罩（17）的凸缘部（17b）与主体（16）的夹持面（91）之间，该隔膜 （17b）与夹紧面（91）之间的最小间隙位置比膜片（28）的径向内侧的间隙的最大间隙小。 由此，能够确保膜片的密封性和拔出阻力，并且能够实现轻量化和低成本化。
