Abstract

The utility model relates to a watertight valve with double-gear flushing, accurate metering and time-delay self closing. When a knob is turned on in a levorotatory way, a spring arm is dragged by a knob rope to leftwards swing, a valve plug is linked and opened for flushing, and flushing water pushes an impeller and links a big gear, a small gear and shafts to rotate. Meanwhile, a hanging hook on the spring arm is also sleeved and hung on the shaft of the big gear with full amplitude. Along with the rotation of the shaft of the big gear, the hanging hook carries out retreat movement. After the hanging hook retreats completely, the water with the quantity of 3 liters is already flushed out by a flushing valve, and the valve plug loses the support of opening and is closed. When the knob is turned on in a dextrorotatory way, the hanging hook on the spring arm only can be hung by less than one half. When the hanging hook retreats completely, the quantity of the flushing-out water is only 1 liter.

When left rotarily opens knob, knob rope traction return spring arm is put row left, at this moment return spring arm is opened the valve plug of flushing valve on the one hand, drive its hook that is movably connected on the former repeatedly spring arm recovery on this arm on the other hand along hook leading wall left lateral, when the hook termination surpasses Large Gear Shaft During, pack in hook that the hook cover is hung on the Large Gear Shaft During under the propelling of spring, at this moment hook will be in the amplitude of full stroke, so, make hook all withdraw from above the average age for marriage wheel shaft, just need the more revolution of impeller rotation, corresponding washing water quantity also can be more, and Here it is, and stool is washed gear.

Through debugging, this valve just can accurately realize resembling 1---3 liters discharging quantity of water.If being 200620002667.6 valve pocket, the patent No. that this flushing valve adapted is formerly invented seals smelly pan and water closet, then comparable existing pan is economized on water more than 84.2% accurately, self-evident, this will be to society and user's water saving this how to have significant meaning.
