Water in second back pressure cavity 141 is after the outflow of the second relief hole 142 again through (now, the 3rd relief hole 143 of the 3rd relief hole 143
In open mode) pressure-releasing chamber 176 is flow to, the water for flowing to pressure-releasing chamber 176 is finally discharged to outside from the concentration of discharge outlet 177, sluices
Cause the back-pressure of the first back pressure cavity 112 and the second back pressure cavity 141 to be die-offed afterwards and be far below first, second intake tunnel 110,
Intake pressure in 140, describe for convenience, the first back pressure cavity 112 and the second back pressure cavity 141 hereinafter referred to as now are in phase
To low-pressure state, so, under the water feeding pressure effect in the first intake tunnel 110 and the second intake tunnel 140, the first back pressure
The back pressure diaphragm 145 of diaphragm 114 and second, which moves up, opens the first exhalant canal 120 and the second exhalant canal 150, at the same time, the
First, the water in the second intake tunnel 110,140 respectively enters first, second by the first water hole 111 and the second water hole 144
Discharged in back pressure cavity 112,141 and from first, second relief hole 113,142.Due to now, first back pressure cavity 112 and institute
State the second back pressure cavity 141 and be in relatively low pressure state, therefore, the piston 174 in time delaying hydraulic cylinder 172 is in piston reset elastic component
Water in the presence of 175 during extrolling in chamber 171 makes it slowly flow out into the first back pressure cavity 112 from delay spilled water hole 173
Interior, because delay spilled water hole 173 is smaller, therefore sluicing speed is slow, causes the activity of piston 174 slowly, and then cause and piston 174
The sealing part 178 of linkage is slowly close to the 3rd relief hole 143, until the 3rd relief hole 143 of sealing of sealing part 178, due to second
Water in back pressure cavity 141 can not continue to release, and cause the back-pressure of the second back pressure cavity 141 to increase (the second back pressure cavity now
141 back-pressure is equal with the intake pressure in the second intake tunnel 140) so that the second back pressure diaphragm 145 move down it is close
