    • A method for operating a fluid drainage control system to drain a fluid from a fluid dispensation system is provided. The method includes determining a first ambient air temperature, determining if the first ambient air temperature is less than a predetermined drain set point temperature, isolating the fluid dispensation system from a fluid supply source by closing a supply valve located inside a temperature controlled area in response to the first ambient air temperature being less than the predetermined drain set point temperature, and draining the fluid from the fluid dispensation system by opening a drain valve subsequent to closing the supply valve. The method further includes determining a second ambient air temperature, determining if the second ambient air temperature is greater than a predetermined operation set point temperature, closing the drain valve in response to the second ambient air temperature being greater than the predetermined operation set point temperature, and opening the supply valve subsequent to closing the drain valve.
    • 提供了一种用于操作流体排出控制系统以从流体分配系统排出流体的方法。 该方法包括确定第一环境空气温度,确定第一环境空气温度是否小于预定的排水设定点温度,通过关闭位于温度受控区域内的供应阀来响应流体分配系统与流体供应源的隔离 到第一环境空气温度小于预定排水设定点温度,并且在关闭供应阀之后打开排放阀,从流体分配系统排出流体。 该方法还包括确定第二环境空气温度,确定第二环境空气温度是否大于预定操作设定点温度,响应于第二环境空气温度大于预定操作设定点温度来关闭排水阀, 并且在关闭排水阀之后打开供给阀。

    • A water or other fluid containing system is protected by a thermostatically controlled drain valve having input, output, drain and control ports. A slideable barrier within the valve selectively directs the flow within the valve between the ports. A small coupling orifice through the barrier and a particularly designed closure for the orifice are provided. A thermosensitive mechanism delivers pressure to the control port to open this closure when ambient temperature drops below a predetermined level. Equal static pressures developed by flow through the orifice in turn develop unequal forces on opposite sides of the barrier, to shift the barrier, redirecting the flow within the valve.
    • 水或其它含流体系统由具有输入,输出,排水和控制端口的恒温控制排水阀保护。 阀内的可滑动屏障选择性地引导阀之间的流动在端口之间。 提供了通过阻挡件的小联接孔和用于孔口的特别设计的闭合件。 当环境温度下降到预定水平以下时,热敏机构将压力传送到控制端口以打开该关闭。 由通过孔口流动而产生的相等的静压力又在阻挡层的相对侧上产生不相等的力,以移动障碍物,重新定向阀内的流动。
