    • A bellows type pressure responding valve having a sealed bellows (66) as a pressure sensing element and adapted to change a valve opening by transmitting the expansion/contraction of the bellows (66) to a valve disc (61) via a valve stem (65) supported by a valve housing (51) movably in a valve lift direction, wherein a spherical joint structure consisting of a ball (77) disposed coaxially with the valve stem (65) and a spherical recess (78) formed at the bellows center position of a closing end face (67a) at the bellows body (67) of the bellows (66) is assembled into a connection between the bellows (66) and the stem (65) to spherically connect the bellows (66) with the stem (65) by the spherical joint structure, thereby delivering an automatic centripetal action between the bellows and the stem to provide high-accuracy valve control characteristics.
    • 一种波纹管式压力响应阀,其具有作为压力检测元件的密封波纹管(66),并且适于通过阀杆(65)将波纹管(66)的膨胀/收缩传递到阀盘(61)来改变阀开口 )由阀门壳体(51)支承,阀门壳体(51)可在阀门升程方向上移动,其中由与阀杆(65)同轴设置的球(77)和形成在波纹管中心位置的球形凹槽(78)组成的球形接头结构 (66)的波纹管本体(67)处的关闭端面(67a)组装成波纹管(66)与杆(65)之间的连接,以将波纹管(66)与杆( 65),由此在波纹管和杆之间提供自动向心作用以提供高精度的阀控制特性。 <图像>
