Ship lock dynamic water valve closing process debugging method capable of shortening water filling time
The invention provides a ship lock flowing water valve closing process debugging method capable of shortening water filling time. The method comprises the following steps that 1, the water level in alock chamber is flush with the downstream water level, a downstream miter gate is closed, and a drain valve is closed; 2, a water filling valve is opened to fill water until the water filling valve isin a fully open state; 3, when the residual water head value reaches H, a water filling valve is started to be closed, when the water filling valve is closed to the opening degree n, the valve closing action is stopped, water filling is continued till the water level of the lock chamber is flush with the upstream water level of the ship lock, the miter gate is opened to the end of opening, and the waiting flush time delta(t) value and the inertia ultrahigh value delta(h) are calculated; 4, according to the delta(t) value and the delta(h) value, the remaining water head value delta(H) or the valve closing opening value delta(n) of the water filling valve is adjusted; 5, repeating the step 1 and the step 3 for debugging by adopting the adjusted delta(H) and n values, and synchronously calculating delta(t) and an inertia ultrahigh value delta(h). The process for closing the valve by moving the water in advance of the valve can ensure the running of the miter gate and the berthing safetyof a lock chamber ship, and can shorten the water filling time.
本发明提供的一种缩短充水时间的船闸动水关阀工艺调试方法，包括以下步骤：步骤一、闸室内水位与下游水位齐平、下游人字门关闭、泄水阀门关闭；步骤二、开启充水阀门进行充水，直至充水阀门处于全开状态；步骤三、当剩余水头值达到△H时，开始关闭充水阀门，当充水阀门关至开度n时，停止关阀动作，继续充水直至闸室水位与船闸上游水位齐平，人字门开启至开终，计算等待齐平时间△t值和惯性超高值△h；步骤四、根据△t及△h值，对剩余水头值△H或充水阀门的关阀开度值n进行调整；步骤五、采用调整的△H及n值，重复步骤一~三进行调试，同步计算△t和惯性超高值△h。确定既能保证人字门运行及闸室船舶停泊安全，又能缩短充水时间的阀门提前动水关阀工艺。
