    • The present invention relates to a valve arrangement (1) comprising a valve housing (2), a valve inlet (3), a valve outlet (4) and a diaphragm assembly for controlling a fluid flow through the valve housing (2) from the valve inlet (3) to the valve outlet (4), the diaphragm assembly comprising a diaphragm (5) and a diaphragm plate (6) at least partially covering the diaphragm (5), the diaphragm (5) comprising one or more equalization holes (13) passing through the diaphragm (5) and the diaphragm plate (6) comprising one or more equalization openings (12) passing through the diaphragm plate (6), the equalization holes (13) being aligned with the equalization openings (12). According to the invention, the diaphragm assembly comprises an engagement zone engaging the diaphragm (5) in order to rotationally fix the diaphragm (5) and the diaphragm plate (6) with respect to each other. This has the effect that the equalization holes (13) will keep aligned with the equalization openings (12). Thus, proper function of the valve arrangement (1) is ensured at all times. Furthermore, the invention relates to a diaphragm assembly for a valve arrangement (1) as described above.
    • 本发明涉及一种包括阀壳体(2),阀入口(3),阀出口(4)和隔膜组件的阀装置(1),所述隔膜组件用于控制流体流过 从所述阀入口(3)到所述阀出口(4)的所述阀壳体(2),所述隔膜组件包括隔膜(5)和至少部分地覆盖所述隔膜(5)的隔膜板(6),所述隔膜 5)包括穿过所述隔膜(5)和所述隔膜板(6)的一个或多个均衡孔(13),所述均衡孔包括穿过所述隔膜板(6)的一个或多个均衡开口(12),所述均衡孔 与均衡开口(12)对齐。 根据本发明,隔膜组件包括与隔膜(5)接合的接合区域,以便将隔膜(5)和隔膜板(6)相对于彼此旋转地固定。 这具有均衡孔(13)将与均衡开口(12)保持对齐的效果。 因此,始终确保阀装置(1)的适当功能。 此外,本发明涉及如上所述的用于阀装置(1)的隔膜组件。

    • The invention relates to a valve (1) comprising a main valve (2), a pilot valve (3), a housing (4), an inlet (5) and an outlet (8). Opening and closing of the main valve (2) is controlled by the pilot valve (3). A pilot valve seat (10) is arranged in a diaphragm (6). A pilot chamber (11) is arranged in the housing (4) separated from the inlet (5) and the outlet (8) by the diaphragm (6). Task of the invention is to provide a valve with a lower cost. According to the invention a support member (17) supports the diaphragm (6), wherein the support member (17) is guided in the housing, and wherein a radial gap (26) is arranged between the radially outer end of the diaphragm (6) and the housing (4) in a radial direction perpendicular to the opening direction of the pilot valve (3). Thereby, a cheaper, less resistant material for the diaphragm can be used.
    • 本发明涉及包括主阀(2),先导阀(3),壳体(4),入口(5)和出口(8)的阀(1)。 主阀(2)的打开和关闭由先导阀(3)控制。 导向阀座(10)布置在隔膜(6)中。 引导室(11)布置在通过隔膜(6)与入口(5)和出口(8)分离的壳体(4)中。 本发明的任务是提供一种成本较低的阀门。 根据本发明,支撑构件(17)支撑隔膜(6),其中支撑构件(17)被引导到壳体中,并且其中径向间隙(26)布置在隔膜(6)的径向外端之间 )和壳体(4)在垂直于先导阀(3)的打开方向的径向方向上。 因此,可以使用用于隔膜的更便宜,更小的耐受材料。
