When the pipeline produces condensate, trap enclosure cooling, the trap begins to drain; in the superheated steam pipe on the absence of condensate production, trap does not open, the work of high quality.

当管线截止阀产生凝结水，疏水阀外壳降温，疏水阀开始排水；在过热蒸汽管线上如果没有凝结水产生，疏水阀不会开启，工作质量高。

Pressure-relief valve is installing to use , should open the shut-off valve of the road of bypass pipe , remove the mixture of soda and the condenser water in pipeline, in order to avoid that pressure-relief valve produce water when opening 圾 phenomenon damage pressure-relief valve, will be the same as frequently phenomenon rear, press to obey the direction of hour hand slow revolving regulation screw, adjust outlet pressure to needed pressure ( is subject to valve rear gauge pressure ), adjustment is rear, carry locknut , twist protection cover.

减压阀在安装使用时，应把旁通管道的截止阀打开，排除管路中的冷凝水和汽水的混合物，以防减压阀开启时产生水圾现象损坏减压阀，当无异常现象后，按顺时针方向缓慢旋转调节螺钉，将出口压力调至所需的压力，调整后，将锁紧螺母背紧，拧上防护罩。

Ignition performance, off the performance, combustion gas proportional valve capacity is a measure of the performance level of the main technical indicators, namely the import and export mapping proportional valve pressure (P2-P2) performance curve, outlet pressure and coil current (P2-I) curve, current and flow curve, and the data of these curves is proportional valve performance testing gas key.

点火性能、熄灭性能、燃烧能力是衡量燃气比例阀性能高低的主要技术指标，截止阀即测绘比例阀进出口压力（P2-P2）性能曲线、出口压力与线圈电流（P2-I）曲线、电流与流量曲线，以及这些曲线有关数据，是燃气比例阀性能测试的关键。

Plug into the part called the valve seat ring head out through the top portion of valve rod called a spool.

阀芯插入阀座环的部分叫做阀芯头，而通过截止阀顶部伸出的部分叫做阀芯杆。

In addition to this valve disc is free to lift, the other part of the same as the cut-off valve, the fluid pressure valve from the valve seat sealing surface of valve lift, medium return A42C Type Pound-Grade Low Lift Spring Loaded Safety Valve led to a seat on the disc down and cut off the flow.

此阀门除了阀瓣可以自由地升降之外，其余部分如同截止阀一样，流体压力使阀瓣从阀座密封面上抬起，介质回流导致阀瓣回落到阀座上，并切断流动。

All NIBCO pressure-rated bronze gate, globe, check and bronze ball valves are manufactured in NIBCO's Nacogdoches, Texas, plant.

所有美国尼伯科额定压力青铜闸阀、截止阀、止回阀和青铜球阀都是在美国德克萨斯州的尼伯科工厂制造。
