- Crane cast steel swing check valves can be furnished with outside lever and adjustable weight when so ordered. 如果用户需要，美国克雷恩旋启式止回阀可以配置外置杠杆和调节压铁。
- Tilting Disc Check valves are similar to swing check valves. In most installations, slamming is minimized upon reversal of flow so noise and vibration are reduced. 翻转式阀瓣止回阀与旋启式止回阀类似。对于大多数安装的翻转式阀瓣止回阀,由于流体倒流造成的撞击程度最小,因此噪音和振动也有所减小。
- There is no tendency for the seating surfaces of swing check valves to gall or score, because the disc meets the flat seat squarely without rubbing contact upon closing. 旋启式止回阀的阀座表面不存在磨损或刮伤的倾向,因为阀瓣与平面阀座相适应,不会在关闭时产生摩擦接触。
- For best performance swing check valves should operate with fluid velocity sufficient to hold the disc in a stable position off the seat or fully open against the disc stop. 为了获得最好的性能，旋启式止回阀应该运行在流量速度足够将阀瓣稳定支撑在离开阀座的位置，或让阀瓣停止在全开的位置。
- Swing check valves can be adversely affected by turbulence if placed too closely to other piping components such as pumps, control valves, meters, reducers, tees, elbows, etc. 如果过于靠近其它管道部件，如泵，控制阀，仪表，收缩管，三通，弯管，等等，旋启式止回阀可能会被湍流反作用。
- General Installation Information: Sump Pump Swing Check Valves may be installed in either vertical up-flow (see illustration) or horizontal positions on pump discharge line. 一般安装信息：水坑泵旋启式止回阀既可安装在垂直朝上（参阅图示）的泵排放管道上，也可安装在水平的泵排放管道上。
- In general a minimum of 10 pipe diameters of straight pipe should be provided upstream of a swing check valve to minimize adverse conditions. 通常，旋启式止回阀与上游部件的距离至少要有管道直径的10倍，这样才能够将反作用降到最小程度。
- 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。
- 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。
- Certain system configurations involving direct connection of a Swing Check Valve to other flanged equipment may require consideration of this bolt clearance. 某些系统配置，包括旋启式止回阀直接连接到其他法兰设备的场合可能要求考虑这种螺栓所需要的间隔。
