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。

Benefits: In addition to a gate valve, globe valve advantages, there are small, sealed, the advantages of easy operation.

优点：除具有闸阀、截止阀的优点外，还有体积小、密封好、易操作的优点。

This less restrictive flow path design improves flow while maintaining the same excellent throttling characteristics as a globe valve.

这种结构对流道的阻力较小，从而在保持截止阀具有相同的节流性能的基础上改善了截止阀的介质流动性。

By adjusting the opening varies of the electronic expansion valves according to the exterior air temperature detected by a temperature sensor, the following is achieved: great heating/cooling efficiency irregardless of the operational conditions, a simple structure, and an air conditioner of smaller size, using electronic expansion valves to adjust the circulation speed of the exchange medium.

电子膨胀阀根据温度传感器检测的外界空气温度，调节其开启程度。得到高加热／制冷效率，而与运行状态无关。通过电子膨胀阀调节热交换介质的流速，得到一个结构简单、尺寸较小的空调器。

In the light of the problems with imported offshore wellhead, such as being bulky and expensive and being inconvenient to mount and maintain, Model HKY65―21 offshore wellhead is developed. This wellhead consists of tubing head assembly, PHK plate gate valve, safety valve, stop valve, clamp, small four-way connection and choke, and it is small-sized, light-weighted, high-strength, corrosion- and abrasion-resistant, reliably sealed and convenient to mount and maintain. Application shows that the wellhead can satisfy the requirements of offshore production with good performance.

针对海上油田所用国外采油井口装置存在体积庞大笨重、价格昂贵以及与国产设施不配套和安装维护不便等问题，研制了HKY65―21型海上井口装置这种井口装置主要由油管头总成、PHK平板闸阀、井口安全阀、截止阀、卡箍总成、小四通和节流器组成，具有体积小、重量轻、强度高、防腐耐磨、密封可靠和安装维护方便等优点现场使用128套的实践表明，其各项技术性能指标均能满足海洋石油生产的要求，完全可以取代进口产品，经济效益可观

Bellows Gate Valves However, in large differential pressure operating conditions, evaporation pressure has eased, the evaporator load requirements of the fluid volume decreased, but the actual situation the contrary, in the suction superheat unchanged, due to evaporation pressure has eased, the evaporator outlet pressure be reduced accordingly, pressure changes above and below the diaphragm, causing the main valve opening increases for increased fluid; but in a small pressure operating conditions, evaporation pressure rise, evaporator load demand for fluid volume increased, but the reality is that in the suction gas superheat unchanged, due to evaporation pressure rise, a corresponding increase in the evaporator outlet pressure, pressure difference above and below the diaphragm smaller, so that the main valve opening decreased for the reduction of liquid volume; in variable load is all about.

但在大压差工况下，蒸发压力降低，蒸发器负荷需求的液量减少，但实际情况相反，在吸气过热度不变的情况下，由于蒸发压力降低，蒸发器出口压力相应降低，膜片上下的压差变大，使主阀开度增大，供液量增加；但在小压差工况下，蒸发压力上升，蒸发器负荷需求的液量增多，但实际情况是在吸气过热度不变的情况下，由于蒸发压力上升，蒸发器出口压力相应提高，膜片上下的压差变小，使主阀开度减小，供液量减少；在变负荷下亦如此。

The flow capacity of large-size small Straight trip valve flow capacity is to install the pipeline flow capacity of valve scores, improve flow capacity is to increase the size of straight travel valve is usually larger than pipelines.

流通能力大尺寸小直行程阀的流通能力是安装阀的管道流通能力的分数，提高流通能力的方法是提高直行程阀的尺寸，通常可能比管道还大。

Angle type valve to cut off travel greater pressure is due to media in the spool or the valve plate force generated by the rotational axis of the torque produced is very small, so it can withstand a greater pressure differential.

角行程类阀的切断压差较大，是因为介质在阀芯或阀板上产生的合力对转动轴产生的力矩非常小，因此，它能承受较大的压差。

Angle type valve to cut off travel greater pressure because of media in the spool or the valve plate force generated by the rotational axis of the torque produced is very small, Check Valves so it can withstand a greater pressure differential.

角行程类阀的切断压差较大，是因为介质在阀芯或阀板上产生的合力对转动轴产生的力矩非常小，因此，它能承受较大的压差。

Turn it back on and set the box cover at the right, and then set the pumb output tubes and machine into the tubing connected, and then on the machine: the pumb work grow up immediately, and mold hold its output tube is also apparent from inside the pent up spilling in output occurred at both the reliability and vibration grow up; then view the instructions in the oil pressure table has been rising "" 0 to "" 5, at the same time, pressure relay (and by keeping the switchboard AC closing in — from its contact outgoing voltage) order lubrication solenoid valve work of fuel, oil pressure decreased and quickly rose to require lubrication with pressure-a solenoid valve, so self-repeating.

重陈不兵其拧不松并不兵盒盖上好，再不兵油泵输入惯与机械的不退油惯接开，然后试机：油泵处事的声音当即变不小了，且用手捏握其输入惯也暗显感触边面流油的鼓胀度和震不不静度均变不小了；再不雅油压外洋的辅导已由&0&逐步上降到了&5&，与此同时，不张力继电器不不静息（并开功使配电柜内互换隔绝器呼分——由其触不面传不入电压）令润滑电磁阀处事——放油，油压回降后又迅不缓上降至规矩不张力后再令润滑电磁阀放油，如此轮回来往。
