starting valve

Starting from the analysis on the characteristics of the measured object the accuracy and functions of the system are considered comprehensively. The automatic testing system for balancing valve and d/ p valve which is based on the industrial PC open architecture is introduced.

从分析被测对象的特性入手，综合考虑了系统的精度和功能，介绍了基于工业PC的开放式结构的平衡阀、差压阀自动测试系统。

Type V ball valve uses duplex bearing, so its mechanical stability is very high and the starting torque is small.

由于V型球阀采用双轴承结构，机械稳定性高，起动扭矩小。

The simulation of LO_2 tank pressurization system indicates that PID control parameters should be set reasonably and the initial opening of pneumatic diaphragm control valve should be adjusted to nominal pressurant mass rate, which is effective to improve stability of pressurization starting transient.

对贮箱增压系统的仿真表明，合理设计PID控制参数并根据经验预置与额定流量相近的调节阀初始开度，对于提高增压系统起动过程的平稳性有利。

Determine GPM flow by use of valve Cv curve starting page 5.

要确定每分钟多少加仑流量,则要采用从第5页开始的阀门流量曲线.

The supplier shall provide adequate on-site service and after-sale support and assign qualified representatives for assisting the installation, commissioning, starting and on-site training of the jacket ball valve.

供货商应提供强有力的现场服务与售后支持，并配备有资格的现场代表配合夹套球阀（jacketballvalve）的安装、试运行、启动、和现场培训。
