Whenever embodiment 9: working principle of the present utility model is: the breather cheek valve of the general automatic water drainage device of positive and negative pressure is connected to outside atmospheric valve (when guarantee needs, outside air can enter tailrace, and gas can not through its reverse outflow in tailrace), intake pipe is connected with the container (hereinafter referred to as gas conveyer tube) of pressure-equalizing pipe with gas conveyer tube or splendid attire gas, pressure-equalizing pipe has been communicated with tailrace and gas conveyer tube, make pressure between the two equal, under the state be hedged off from the outer world, no matter the polarity of pressure is plus or minus, the water accumulated in gas conveyer tube all can flow into tailrace through intake pipe and store (receipts water state) under the effect of self gravitation, and no matter the polarity of pressure is plus or minus, under the effect of counterweight, only have when water level in tailrace rise to blowoff valve body be submerged in (being isolated from the outside by gas with water) of certain depth under water time, cursory could with counterweight and pallet component (pallet, magnet, side guide rod, centre pilot bar, cursory block, be the entirety firmly linked together during seal work, be called for short pallet component, lower same) rise, buoyancy valve (blowoff valve body+seal+centre pilot bar+pallet) is opened, ponding flows in buffer cavity, for " discharging water " ready work.Now;
If pressure is just, inlet pressure is higher than outlet pressure, and water check valve is open-minded, enters " malleation discharges water " state, and now " receipts water " and " discharging water " are carried out simultaneously, and by the balance of cursory elevating control retractable water;
If pressure is negative, outlet pressure is higher than inlet pressure, and water check valve is closed, and tailrace maintains " receipts water " state;
As timing during pressure is born, then change therebetween at " malleation discharges water " and " receipts water ".
As negative pressure is held time very long, when cursory rise to limiting altitude time, being fixed on pallet and the magnet above to cover can unexpected adhesive, and pallet rises instantaneously and puts in place; Pressure-equalizing pipe blocks by the sealing gasket on it, atmospheric valve (air inlet valve body+sealing head) is opened (sealing head is backed down by side guide rod), ambient air enters tailrace through breather cheek valve, inlet hole (on air inlet valve body), the pressure of its inside is very fast identical with the external world, because outlet pressure is higher than inlet pressure, one-way water inlet valve is closed, tailrace and gas conveyer tube completely cut off, under the effect of hydrostatic pressure, tailrace internal water accumulation flows out through water check valve, enters " static pressure discharges water " state.
Along with water level decreasing, cursory meeting drops to and is hung on cursory block, along with water level continues to decline, and F under(pallet component heavy+ counterweight heavy+ cursory heavy-cursory floating) increase gradually, work as F on(magnet inhale+ negative pressure inhale) < F undertime, magnet discharges, and pallet can plunk down, and tailrace is communicated with gas conveyer tube, and the pressure in tailrace becomes rapidly negative, then atmospheric valve, water check valve are closed under the effect of inside and outside differential pressure, and one-way water inlet valve is opened, and enters " receipts water " state.A beginning new round " receive---put " water circulation.
As the polarity in magnet attraction state downforce is just becoming, then
F on=magnet inhale;
F under=malleation push away+ pallet component heavywhile not tangled by cursory block (cursory),
Or,
F under=malleation push away+ pallet component heavy+ counterweight heavy+ cursory heavy-cursory floatingwhile being tangled by cursory block (cursory),
(buoyancy of pallet component is far smaller than cursory buoyancy, can ignore);
F on< F undertime, magnet discharges, and pallet falls, and tailrace is communicated with gas conveyer tube, and the pressure in tailrace is just becoming rapidly, and breather cheek valve is closed under the effect of inside and outside differential pressure, and water check valve is opened, and enters " malleation discharges water " state.
F on>=F undertime, magnet maintains adhesive, pressure-equalizing pipe is still blocked, but pressure also acts on tailrace by aqueduct, when pressure is greater than the U-shaped curved water column pressure of aqueduct, residual pressure acts on tailrace inside, state that tailrace enters " micro positive pressure discharges water ", otherwise maintain " static pressure discharges water " state, and along with water level decreasing, F underincrease gradually, until F on< F under, magnet discharges, and pallet falls, and enters " malleation discharges water " state.
The matching principle of counterweight;
1., during original state, itself and pallet component, cursory gravity sum can ensure the sealing of buoyancy valve.
2. in tailrace water level rise to blowoff valve body be submerged in certain depth under water time, the cursory counterweight that just can carry rises together with pallet component.
3., in " static pressure discharges water " process, when blowoff valve body is still submerged under the water level of certain depth, magnet is discharged.
