1·A test and pressure relief valve should be installed to assure relief of internal pressure prior to servicing and as a visual indication of trap operation.
应该安装一个测试和压力安全阀，确保内部压力能够在维修前得到释放，并作为疏水阀工作的直观显示。
2·A check valve should be installed on return piping if there will be a pressurized return line or the trap drains to an overhead return line (Fig. B).
如果存在一个压力回路，或者疏水阀排放口位于回路管道的上方，则应该安装一个止回阀(图b)。
3·The flat bottom gate provides full perimeter seating against the seat, eliminating pocket in the bottom of the seat that can trap process media and prevent the valve from fully closing.
平坦的闸板底部与阀座之间能够实现全周长阀座密封，避免阀座出现可能淤积流体介质、妨碍阀门完全关闭的底部洞隙。
4·Pneumoceles may occur suddenly, presumably by a trap-valve mechanism or by rupture of a large mucocele.
窦膨出可见突然发生，大概是一种滤网机制或者是一个大的黏液囊肿破裂所致。
5·Keep return piping valve closed until trap fills with condensate. Slowly open valve.
保持回路管道阀门处于关闭状态直到疏水阀充满冷凝物为止。慢慢开启阀门。
6·The steam trap is a valve that releases condensate water in steam pipe network system.
蒸汽疏水阀是一种用于蒸汽管网系统中疏导冷凝水的阀门。
7·Import import trap or trap is known for the steam pipe network and devices, can automatically discharge condensate, air and other non-condensing gas, and blocking water vapor leak valve.
进口疏水阀或称进口疏水器是用于蒸汽管网及设备中，能自动排出凝结水、空气及其它不凝结气体，并阻水蒸汽泄漏的阀门。
8·The design of the slanting valve trap keeps the valve door tightly closed when the pressure from the backflow gets higher, allowing the valve trap to perform its best function.
活门的斜角位设计，当回流压力越大，活门越能紧闭，发挥最佳的防回流功能。
9·This invention relates to structural changing of the waste water drain trap in housing construction and the double valve water tank of the waste water filter and sanitary ware urinal.
本发明涉及改变住宅建设排水管结构及废水过滤器和卫生洁具便池双阀水箱，改变各楼层废水排水管结构利用二次水自流过滤流入便池水箱冲洗便池及冲洗拖布。
10·Pneumatic Angle. Vent valve, filter, the drain valve, the valve, the diaphragm valve, cock, piston valve, valve, valve, copper heat water valves, balance valve, trap, solenoid valves.
排气阀、过滤器、排污阀、底阀、隔膜阀、旋塞阀、柱塞阀、铜阀门、保温阀门、水利控制阀、平衡阀、疏水阀、电磁阀。
