    • A sewer pipe gas exhaust filter apparatus includes a sewer vent valve unit connected to a sewer pipe and including a valve member moved into and out of engagement with a valve seat by a float member, a gas filter unit connected to the sewer vent valve unit and including a gas filter medium, and a gas flow valve arrangement to cause gases from the sewer to flow through the filter medium while bypassing air drawn into the sewer pipe past the gas filter unit. The filter medium of the gas filter unit removes chemical components from air and gas exhausted from the sewer pipe, thereby improving the odor of such exhausted gases.
    • 下水道排气过滤装置包括:下水道排气阀单元,连接到下水道,并且包括通过浮子构件移动进入和脱离与阀座接合的阀构件;连接到下水道排气阀单元的气体过滤器单元; 包括气体过滤介质和气流阀装置,用于使来自下水道的气体流过过滤介质,同时绕过吸入到下水道中的空气通过气体过滤器单元。 气体过滤器单元的过滤介质从下水道排出的空气和气体中除去化学成分,从而改善排气的气味。

    • An apparatus for purging air from a fluid conveying tube includes a housing member comprising an inner bore having an inlet and an outlet (115); and a vented piston member slidably disposed within the inner bore, the vented piston member comprising a filter element and at least one air vent. The filter element is configured to allow air to pass through the vented piston member to the at least one air vent and to prevent fluid from passing through the vented piston member to the at least one air vent. A method of purging accumulated air from a fluid conveying tube includes providing a vented piston member slidably disposed within a housing member; displacing air from the fluid conveying tube through a filter element disposed within the piston member using pressurized fluid; and displacing the piston member with the pressurized fluid; wherein the displacement of the piston member exposes an outlet for the pressurized fluid.
    • 用于从流体输送管吹扫空气的装置包括壳体构件,其包括具有入口和出口(115)的内孔; 以及可滑动地设置在所述内孔内的排气活塞构件,所述排气活塞构件包括过滤元件和至少一个排气口。 过滤元件被构造成允许空气通过排气的活塞构件到达至少一个排气口并且防止流体通过通气的活塞构件到达至少一个排气口。 从流体输送管吹扫积聚的空气的方法包括提供可滑动地设置在壳体构件内的排气活塞构件; 使用加压流体将空气从流体输送管移动通过设置在活塞构件内的过滤元件; 并且用所述加压流体移动所述活塞构件; 其中所述活塞构件的位移暴露所述加压流体的出口。

    • A normally open check valve, incorporating a bell-shaped check valve member, and filter assembly incorporating same, wherein the specific gravity of the bell shaped member volume as defined by the throat, and exterior wall of the bell shaped member is less than one, and the bell shaped member is disposed adjacent a valve seat in a chamber with the throat opening thereof generally facing a liquid source, among other things. The low specific gravity for the bell shaped member volume may be attained by way of example, by the bell shaped member interior capturing and retaining a gas bubble when the throat of the member is exposed to a liquid-gas interface, or by a thin member covering the throat of the bell shaped member to encapsulate a gas bubble, or by a foamed synthetic resin material in the interior of the bell shaped member, or a combination thereof.
    • 具有钟形止回阀构件的常开止回阀和包括钟形止回阀构件的过滤器组件,其中由喉部形成的钟形构件体积的比重和钟形构件的外壁小于1, 并且钟形构件设置在腔室中的阀座附近,其中喉部开口大致面向液体源。 钟形构件体积的低比重可以通过示例来实现,当构件的喉部暴露于液 - 气界面时,钟形构件内部捕获并保持气泡,或者通过薄构件 覆盖钟形构件的喉部以封装气泡,或者通过泡沫合成树脂材料在钟形构件的内部或其组合中。
