Water exit into pressure-releasing chamber 176 from the first relief hole 113 at once, the water in the second back pressure cavity 141 from
After second relief hole 142 outflow, through the 3rd relief hole 143, (now, the 3rd relief hole 143 is in and beats again
Open state) it flow to pressure-releasing chamber 176, the water flowing to pressure-releasing chamber 176 is finally discharged to from discharge outlet 177 concentration
Outside, causes the back-pressure of the first back pressure cavity 112 and the second back pressure cavity 141 to be die-offed and the lowest after sluicing
In first, second intake tunnel 110, the intake pressure in 140, describe for convenience, be hereinafter referred to as this
Time the first back pressure cavity 112 and the second back pressure cavity 141 be in relatively low pressure state, so, enter first
Under water feeding pressure effect in aquaporin 110 and the second intake tunnel 140, the first back pressure diaphragm 114 He
Move on second back pressure diaphragm 145 and open the first exhalant canal 120 and the second exhalant canal 150, same with this
Time, first, second intake tunnel 110, the water in 140 passes through the first water hole 111 and the second water hole
In 144 respectively enter first, second back pressure cavity 112,141 and from first, second relief hole 113,142
Discharge.Due to now, described first back pressure cavity 112 and described second back pressure cavity 141 are in relatively low
Pressure condition, therefore, the piston 174 in time delaying hydraulic cylinder 172 is under the effect of piston reset elastic component 175
During extrolling, the water in chamber 171 makes it slowly flow out into the first back pressure cavity from time delay spilled water hole 173
In 112, owing to time delay spilled water hole 173 is less, therefore sluicing speed is slow, causes piston 174 movable slow
Slowly, and then make the most close 3rd relief hole 143 of sealing part 178 with piston 174 linkage, until
Sealing part 178 seals the 3rd relief hole 143, owing to the water in the second back pressure cavity 141 cannot continue to release,
