1、This allows our swing check valve to close completely even when installed in a horizontal pipe run with no flow.───这使得我们的旋启式止回阀无论安装在水平管道还是垂直管道上，都能够实现完全的关闭。
2、Swing Check Valves operate in response to a fluid stream flow opening a swinging disc.───当流体流动打开旋启式阀瓣时，旋启式阀瓣处于工作状态。
3、Swing Check Valve bodies are ordinary hinge, there is a door the same as the free flap valve against the valve seat sloping surface.───旋启式止回阀有一介铰链机构，还有一个像门一样的阀瓣自由地靠在倾斜的阀座表面上。
4、Swing check valves are used to prevent reversal of flow in horizontal or vertical pipe lines.───旋启式止回阀用于防止水平管路或垂直管路的流体倒流。
5、Double Flanged Style Valves bolt up similar to a bolted cap swing check or gate valve.───双法兰类型阀门采用螺栓紧固，类似于螺栓阀帽旋启式止回阀或闸阀。
6、The swing check valve can also be mounted to the vertical position, provided the disc should not reach the valve position.───旋转式止回阀也可以安装在垂直位置，此时阀瓣应该无法达到阀门的位置。
7、Swing Check Valves additionally allow higher volume of fluid transmission.───此外，旋启式止回阀能够通过的流量更大。
8、Industrial Swing Check models can be fitted with an optional counter balance device to further control closing speed.───工业旋启式止回阀系列可以配置反平衡装置来进一步控制关闭速度。
9、processing contrast experimental investigation into the water hammer for a spherical check valve and swing check valve is conducted.───对球形和旋启式两种止回阀进行了水锤对比试验研究。
