您要查找的是不是：
- excess flow check valve 溢流止回阀
- Use a check valve to prevent reverse flow into the cylinder. 采用止回阀,防止回流入钢瓶。
- Stop the pumps for a flow check. 停泵观察。
- If the RPZ relief valve should open, excess flow through the drain pipe trips the flow sensor which energizes the solenoid on the 113-6RFP valve and it goes closed. 如果减压区安全阀出现开启，过量的流体将通过排放管道，从而激发流量感应器，从而激发113-6RFP上的电磁阀，引起阀门关闭。
- Check valve guiding shall be plastic to plastic. 止回阀引导装置应该是塑料对塑料。
- Purpose: To test check valve No. 2 for tightness against reverse flow. 目的:检测止回阀2号对于回流的密封性。
- When flume discharged at single side, its excess flow should not be too large. 渡槽单联过水时过流量不宜太大，闸门开启时第一开度不宜过大。
- Remove check valve and valve seal from booster. 从倍力器上卸去逆止阀和阀门密封。
- Connect vacuum hose to booster check valve. 连接真空软管到增压器检测阀。
- To test for tightness of second check Valve. 检测第二止回阀的密封性。
- ANSI FLANGED SWING CHECK VALVE CLAS. 美标法兰止回阀。
- Reassemble the Check valve modules. 重新组装止回阀模块。
- All drilling breaks are to be flow checked. 遇到快钻时或钻进放空都要检查溢流。
- Connect vacuum hose to booster check valve . 连接真空软管到增压器检测阀。
- Purpose: To test check valve No. 1 for tightness. 目的:检测止回阀1号的密封性。
- Performance parameters are sinilar to the bi-directional reedle valve but inelude a high capacity free flow check in the return directon. 功能参数同等于双向节流阀但包含一个回转方向的自由流单向阀。
- Sticky outlet check valve poppet. 1检查过滤的进水管线。
- CAUTION: The check valve spring is in compression. 警告：止回阀弹簧处于压缩状态。
- Excessive flow of milk from the breasts during lactation. 乳汁过多在哺乳期从乳房流出过多的乳汁
- Swing Check valves prevent reversal of flow through pipe lines. 旋启式止回阀可以防止管路中的流体倒流。
