Working principle
When in the cylindrical shell 1 of sealing without ponding, the movable plate 2-2 of rotary plate valve 2 is in limit inferior working position, negative tube
11 connect with extraction pipeline, and under the action of extraction pipeline negative pressure, water one-way valve 19 is closed out, and negative pressure is gradually in cylindrical shell 1
Gradually with extraction pipeline negative pressure close to identical, the ponding in extraction pipeline pushes the inflow of water feeding one-way valve 12 open under the effect of gravity at this time
In cylindrical shell 1, tailrace starts water storage, as the float 16 that increases of water level slowly moves up, when plane on float and lifting
When third limit plate 14-3 on bar 15 is contacted, elevating lever is temporarily motionless under the effect of upper ear plate fixed magnet 2-11 the suction-combining force,
When float 16 shakes off the magnetic force of upper ear plate fixed magnet 2-11 upwards, 15 inertia of elevating lever is moved up, and passes through the second limit
Plate 14-2 drives shift fork 2-7 to move up, and is attracted movable plate otic placode 2-10 and lower ear plate fixed magnet 2-9, so that rotary plate valve 2
Movable plate 2-2 turn to limes superiors working position, a through-hole on the through-hole and movable plate 2-2 on fixed plate 2-1 is logical at this time
It crosses snorkel 5 and 1 outside atmosphere of cylindrical shell is connected, the through-hole being connected on fixed plate 2-1 with negative tube 11 is closed, water inlet is single
It is closed to valve 12, water one-way valve 19 is opened out, and tailrace starts to discharge water；With the outflow of 1 internal water accumulation of cylindrical shell, float 16
It slowly moves down, when the 4th limit plate 14-4 on float lower plane and elevating lever 15 is contacted, elevating lever is in the fixed magnetic of lower ear plate
The effect of iron 2-9 the suction-combining force is lower temporarily motionless, when float 16 shakes off downwards the magnetic force of lower ear plate fixed magnet 2-9, elevating lever 15
Inertia moves down, and drives shift fork 2-7 to move down by the first limit plate 14-1, keeps movable plate otic placode 2-10 and upper ear plate solid
Fixed magnet 2-11 is attracted, and the through-hole on through-hole and movable plate 2-2 being connected on fixed plate 2-1 with snorkel 5 is staggered
It is closed with 1 outside atmosphere of cylindrical shell, fixed plate 2-1 is upper and the through-hole of the connection of negative tube 11 and one on movable plate 2-2
The corresponding connection of through-hole, water one-way valve 19 is closed out, and water feeding one-way valve 12 is opened, and tailrace starts to intake again.Such Zhou Erfu
Begin, realizes automatic draining circulation.
