Centripetal Round-Swing Fountain Device
(Mobile Rotating Connector for Fountain)

　　一般的喷泉装置只能是对摇、横摇要在一个圆形的管道上，向心内外摇动是难以做到的。本公司研制改进的圆摇装置就是利用一种活动接头改变了摇动方向，然而达到了向心摆动的效果。安装后的圆摇喷泉，水型婀娜多姿、变幻莫测，有如华尔兹对舞，又如白天鹅在飞翔。增加数控
　　阀门，水型更是千变万化，既能跑动又是摇动。

　　Normal fountain device can only make counter-swing or lateral swing on a round pipe. It is hardly to make centripetal inward or outward swing. The round-swing device researched by the company takes a mobile connector which can change swing direction to reach the result of centripetal swing. After installing, the round-swing fountain has graceful and changeable shapes just like Waltz dance or flying white swan. If adding numeric-controlled valves, water designs can change in thousand of ways in both running and swinging styles.
