Hiding behind the regulator valve control is the steam manifold pressure gauge, and below are the vacuum and steam brake application levers.

从左上角的控制，哨子阀，真空喷射器，锅炉压力和真空计方面，这是蒸汽draincocks控制和截止阀，汽刹车停止背后的调节阀控制阀，喷射蒸汽和威尔泵阀。

Programs are cut-off valve straight valve, gate valve, diaphragm valves and so on.

直行程式的阀有截止阀、闸阀、隔膜阀等。

The following cases, to go with locator: 1, medium pressure high pressure big time; 2, valve diameter is large Forged Gate, Globe, Check Valves (DN 00); 3, high or low temperature control valve; 4, the action necessary to raise the speed control valve; 5, using standard signal, the operation of non-standard spring when the implementing agency (20 ~ 100KPa spring outside the range); 6, when used for sub-process control; 7, when the valve to achieve the reverse action (air to close each open-type gas conversion); 8, need to change the valve's flow characteristic time (you can change the positioner cam); 9, no spring actuator or piston actuator, the proportion of action to achieve the time; 10, electrical signals to operate pneumatic actuator must Distribution - gas valve positioner.

下列情况下，要配定位器： 1、介质压力高、压差大的时候； 2、调节阀口径大时（DN00）； 3、高温或低温调节阀； 4、需要提高调节阀的动作速度时； 5、用标准信号、操作气动管路截止阀非标准弹簧的执行机构时（20～100KPa以外的弹簧范围）； 6、用于分程控制时； 7、使阀门实现反向动作时（气关式和气开式互相转换）； 8、需要改变阀的流量特性时； 9、无弹簧执行机构或活塞执行机构，要实现比例动作时； 10、用电信号去操作气动执行机构时，必须配电-气阀门定位器。

下面所开列情况下，要配定位器：一、介质压力高、压差大的时辰； 2、调节阀口径大时（DN00）； 3、高温或低温调节阀； 4、需要提高调节阀的动作速度时； 5、用标准旌旗灯号、操作气动管路截止阀非标准弹簧的执行机构时（20～100KPa以外的弹簧范围）； 6、用于分程节制时；七、使阀门实现逆向动作时（气关式和气开式互相转换）； 8、需要改变阀的流量特性时；九、无弹簧执行机构或活塞执行机构，要实现比例动作时； 10、用电旌旗灯号去操作气动执行机构时，必须配电-气阀门定位器。

Rotary control valve is a control valve, control valve also includes a number of straight travel valve, such as cut-off valves, gate valves, diaphragm valves.

旋转调节阀是一种控制阀，控制阀还包括一些直行程阀如截止阀、闸阀、隔膜阀。

Compression-type valve: This valve is used as boiler feed water and steam off with a valve, it has a lift check valve and stop valve or angle valve integrated function.

压紧式止回阀：这种阀门是做为锅炉给水和蒸汽切断用阀，它具有升降式止回阀和截止阀或角阀的综合机能。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
