valve-opening time

Meanwhile, the flap valve can be used to adjust weight, spring tension and the bottom outlet valve flap valve opening size to determine the pressure and open and close time.

同时，可以利用调整阀瓣的自重、弹簧的弹力以及阀瓣的底孔大小来确定阀门的开启压力和启闭时间。

The relationship between delay time of the boiler response, the opening time of the valve and the flow through the valve for an actual boiler is obtained.

针对电厂一台实际锅炉，得出了锅炉水位动态响应的延迟时间与伐门开启时间，以及流过伐门流量之间的关系。

Calculation by theoretical analysis may ascertain the ideal rotate speed of variable-speed pump and ideal opening of regulating valve, completes adjust process at one time.

经理论分析计算，确定变速泵理想的转速，确定调节阀理想的开度，调节过程一次完成。
