For the irrigation system without central control system or subcontrol boxes, the flow control depend on the operators. The coefficient of the flow can be 0.6, the flow of pump station is 1573 GPM.

61548；没有配置中央控制系统的也没有场地分控箱的手动喷灌系统，其流量的控制依赖阀门操作工人的操作水平，所以总流量的系数可以取0.6，即泵站流量为1573 GPM

This requires a water temperature-control system, usually consisting of a water pump, filter, heat exchanger, and valving to control chilled water input.

这就要求一个水温控制系统，通常包括水泵、过滤装置、热交换器、阀门以控制冷却水流量。

Actual operating results show that the mathematical model is reasonable, and feasible in theory to build the model of valve control. Provide a new method for the coke oven gas collector pressure control.

实际运行结果表明，该数学模型合理，并且在理论上建立阀门的控制量的模型可行，为焦炉集气管压力控制提供了一种新的方法。

Chongqing Umbro Kemao limited liability companies are state-level hi-tech development zone in Chongqing register a comprehensive high-tech company with independent import and export operation rights, the United States and Israel and the related companies have maintained close cooperation, mainly engaged in modern irrigation , greenhouse, water treatment, mine heap leaching, plant protection machinery, hydraulic control valves, into the exhaust valve, water distribution network distribution system, water plant construction, and automatic control, such as business, covering a variety of system design, production, product wholesale, construction, and projects such as the total package.

重庆恩宝科贸有限责任公司是在重庆国家级高新技术开发区注册的一家高技术综合性公司，拥有自主进出口经营权，与以色列与美国的相关公司保持着密切的合作，主要从事现代灌溉、温室、水处理、矿山堆浸、植保机械、水力控制阀门、进排气阀、输配水管网系统、自来水厂建造、及自动控制等业务，范围包括各种系统的设计、生产、产品批发、工程施工、与项目总包等。

Pneumatic control valves stiction is very common in process industry. A big fluctuation of process will be caused by stiction and productivity will also be lowered.

气动阀门的静摩擦现象在工业过程的控制中非常普遍，易引起控制系统的波动，从而影响生产的正常进行。

To maintain the integrity of the process logic, manual air supply overrides for control and automated valve actuator solenoids are not permitted.

为保持工艺控制的完整性，控制器与自动阀门执行机构的电磁阀不许手动供气取代自动控制。

The Yongjia County great wild goose China valve Limited company is situated at the good communications superiorly, the humanities environment "township of the Chinese pump valve"- the cup northern town, this company specialized production seals the ball valve, the biased half ball valve hardly, low, high-pressured plate gate valve, oil field special-purpose valve, throttle cut-off valve, high-pressured check valve's specialized enterprise.

本阀具有结构先进，体积小，重量轻(较同规格阀减少30%)开启省力(开启力矩为同规格阀的10%～20%)，密封可靠，高效能，高精度，高压差的优点。适用于石油、化工、冶金、电站等部门控制过程使用，特别适宜于油田注水泵出口与配水的压力控制。永嘉县鸿华阀门有限公司地处交通便利，人文环境优越的&中国泵阀之乡&-瓯北镇，本公司专业生产硬密封球阀、偏心半球阀，低、中、高压平板闸阀、油田专用阀，节流截止阀，高压止回阀的专业企业。

When the external control pressure increases to the shutoff pressure setting point of the valve, the external control pressure acting on the underside of the diaphragm, which breaks the balance of the compression of the pressure spring and the latch lever, triggers the latch and disengages valve disc arm from the latch.

当外接控制感应压力﹝即减压下游压力﹞升到此阀关断压设定点时，控制压作用于皮膜下层破坏压力弹簧压缩与闩杆间的平衡，然后扳开闩扣并从闩扣释放阀门封盘。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
