球滴
Ball Drip
美国尼伯科UL认证的止回阀可配置一个自动化球滴。这个球滴安装在消防部分连接的止回阀的轮箍C位置上。出现压力时，止回阀将关闭，但是压力消失后将开启使得谁能够从消防连接处排泄。
An automatic ball drip is available for
NIBCO Underwriter's check valves. The ball drip is installed at
boss location "C" on the check valve of the fire department
connection. It will close against pressure, but will open when pressure
is off allowing water to drain from the fire department connection.
