输出阀

With the development of pneumatic technology, electromagnetic valve coil power getting smaller and smaller, while the PLC 's output power increases, so that between the solenoid valve and the PLC eliminates the need for a number of intermediate links, so that control system becomes easier.

随着气动技术的发展，电磁阀的线圈功率越来越小，而 PLC 的输出功率在增大，使电磁阀与PLC之间省去了许多中间环节，使控制系统变得更简单了。

Some innovative approaches were presented to resolve the problem existing in the first generation of boost compressor by increasing the flow area of fluidics nozzle to decrease pressure drop and erosion attack, adding a new flow path in order to improve boosting effect of the second piston bore, connecting a bypass valve in parallel with throttle valve to set a partial flow and regulate pressure drop.

针对第一代样机存在的问题，提出了改进措施：①增加射流元件喷嘴过流面积来降低压耗和冲蚀破坏；②在射流元件输出道与二级活塞缸之间增加新流道，提高二级活塞缸增压效果；③在节流阀位置并联旁通阀进行分流稳压。

To take positive and negative pressure valve to open three valves, screw pine differential pressure transmitter body and sewage screws for the sewage, the sewage completed tighten the screws;⑦ observe the instructions of instruments, until the output of a normal, if the regulating system, and auto-manual switch.

开启三阀组正负取压阀，拧松差压变送器本体上排污螺丝进行排污，排污完成拧紧螺丝；⑦观察现场指示仪表，直至输出正常，若是调节系统，将手动切换与自动。

开启三阀组正负取压阀，拧松差压变送器本体上排污螺丝停止排污，排污完成拧紧螺丝；⑦观察现场指示仪(guan1 cha2 xian4 chang3 zhi3 shi4 yi2)表，直至输出正常，若是调节系统，将手动切换与自动。

Both kinds of algorithms can improve the static and dynamitic characteristics of the system, and meet the design requirements.

在进行系统整体设计和软、硬件设计时，本文充分考虑了系统的实际工况，设置了手柄信号中位死区，以消除系统的误动作；同时，为适应比例阀的工作频率，利用单片机对PWM输出信号进行了分频处理，保证了通过比例阀的平均电流值不变。

An intelligent control algorithm of two-times regulation of angle error was proposed, which combined neural network control and fuzzy control. Advanced output of neural network control turns off the servo valve switch. Fuzzy control turns on the servo valve switch again for more precise regulation.

该算法应用神经网络控制和模糊控制对转角误差进行分段调整，由ε-NN神经网络输出提前量给开关伺服阀断电，采用模糊控制使伺服阀再次得电进行细调。

In PT-2B SERIES CONTROLLING MODLE the automatic sprinkler system, alarm valve is a critical component, and its role to three factors: connect or disconnect the water supply, the output alarm signal and the prevention of water pumped back into the water supply source, and through the alarm valve can be installed on the system of water supply and alarm device for testing.

在自动喷水灭火系统中，报警阀是至关重要的组件，其作用有三：接通或切断水源、输出报警信号和防止水流倒回供水源，以及通过报警阀可以对系统的供水装置和报警装置进行检验。

For the stability of the flow metering pumps, metering pump flow rate, as some big changes with pressure, you can set the exit of metering pump back-pressure valve, so that the output of metering pump flow rate stability, and then usually selected back-pressure valve The Reducing Valves pressure of the actual use of a metering pump metering pump pressure or slightly less than the use of pressure.

用于稳定计量泵的流量，如某些计量泵的流量随压力变化较大，可在计量泵的出口处设置背压阀，使计量泵的输出流量稳定，这时一般选择背压阀的压力为计量泵的实际使用压力或略小于计量泵的使用压力。

The automatic control system includes system unit and accessory equipment as well as AD converter, DA converter, memory SCR current convertor, hydraulic valves, pumps, voltage, current and pressure transmitters, switching amount I/O board, top hammer, valve position collector, displacement sensor, hexahedron crown and synthesizing block.
