摘要： The present invention relates to a WC-cistern filling valve comprising a liquid inlet assigned to a supply line, a liquid outlet assigned to the cistern, and a closing element which is assigned to a valve passage opening arranged between liquid inlet and oulet and which is switchable by a float in accordance with the liquid level in the cistern for opening and closing the valve passage opening. It is the object of the present invention to provide a low-noise WC-cistern filling valve. This object is achieved in that at least a portion of the liquid outlet is shaped as a thread in the flow direction downstream of the closing element in such a manner that liquid is discharged with a swirl from the liquid outlet to the cistern in the opened state of the closing element.
摘要翻译：本发明涉及一种WC储水池填充阀，其包括分配给供应管线的液体入口，分配给水箱的液体出口以及分配给设置在液体入口和口令之间的阀通道开口的关闭元件，可根据水箱中的液位由浮子切换，用于打开和关闭阀通道开口。本发明的目的是提供一种低噪声WC-蓄水池充气阀。该目的是这样实现的，即液体出口的至少一部分在封闭元件的下游沿流动方向成形为螺纹，使液体在打开状态下以液体出口向水箱中的涡流排出的关闭元件。

摘要： A self-closing valve assembly has a main valve having a seat between a high-pressure input conduit and a low-pressure output conduit, a main valve element movable into and out of engagement with the seat to block and permit flow from the input conduit to the output conduit, and a chamber behind the main valve element pressurizable to press the main valve element against the seat. A small-diameter passage extends from the input conduit to the chamber so that the chamber can be pressurized via the passage from the input conduit to hold the valve element against the seat. A pilot or control valve connected between the chamber and the output conduit can be opened to depressurize the chamber and thereby lift the valve element off the seat. A throttle valve has a throttle body having an outer face exposed to pressurized liquid in the input conduit and an inner face turned toward a mouth of the passage, a formation on the inner face blockingly engageable with the passage mouth, an abutment adjacent the mouth of the passage and operatively engageable with the throttle body so that the pressurized liquid in the input conduit will urge the body toward the mouth of the passage and toward the abutment, a weak spring for holding the throttle body at a spacing from the mouth and from the abutment, and a strong spring effective when the body inner face is against the abutment for urging the body away from the mouth of the passage.
摘要翻译：自动关闭阀组件具有主阀，其具有位于高压输入管道和低压输出管道之间的阀座，主阀元件可移动进入和脱离与阀座接合以阻止并允许从输入管道到输出管道，以及主阀元件后面的腔室可加压，以将主阀元件压靠在座椅上。小直径通道从输入导管延伸到腔室，使得腔室可以经由通道从输入导管加压以将阀元件保持抵靠座椅。连接在室和输出导管之间的先导或控制阀可以被打开以使腔室减压，从而将阀元件从座椅上提起。节流阀具有节流体，其具有暴露于输入导管内的加压液体的外表面和朝向通道口部转动的内表面，内表面与通道口可阻塞地接合，邻接口通道并且可操作地与节气门体接合，使得输入管道中的加压液体将推动身体朝向通道的嘴部并朝向邻接部，用于将节气门体保持在与嘴部和并且当身体内表面抵靠基座以促使身体远离通道的口部时，有效的弹簧是有效的。
