Bottom, second level water tank 2 are located at 1 top of first order water tank, and third level water tank 3 is located at top, and third level water tank 3 is equipped with moisturizing
Mouthful, water supplement port is equipped with water compensating valve 4, and the first order water tank 1 is equipped with discharge outlet, and discharge outlet is equipped with drain valve 5, the benefit
The mouth of a river is connected by floating ball valve of rehydration 6 with every grade of water tank；Neighbouring two layers of water tank is connected by a siphon pipe 7, is located at
Siphon pipe 7 in higher level's water tank is known as upper end siphon pipe, is known as lower end siphon pipe positioned at the siphon pipe of junior's water tank, is located at upper layer
Upper end siphon pipe in water tank is equipped with water inlet, and the lower end siphon tube wall in lower layer's water tank is equipped with water outlet 701, removes
Siphon ball-cock assembly 8 is equipped in other water tanks other than third level water tank, the siphon ball-cock assembly 8 controls on lower end siphon tube wall
The opening and closing of water outlet 701, when water level decreasing to minimum setting position, siphon ball-cock assembly 8 controls water outlet 701 and opens, on water level
When rising to highest setting position, siphon ball-cock assembly 8 controls water outlet 701 and closes.
The siphon ball-cock assembly 8 is sheathed on the siphon pipe of lower end, and siphon ball-cock assembly 8 can be transported relatively up and down along lower end siphon pipe
Dynamic, the siphon ball-cock assembly 8 is used to control the opening and closing of water outlet 701 with the relative motion of lower end siphon pipe.
The siphon ball-cock assembly 8 is connected by floating ball rod (not shown) with control floating ball 801, the control floating ball
801 other end is fixedly arranged on roof, and the siphon ball-cock assembly 8 is equipped with vertical chute (not shown), and the floating ball connects
Bar can relatively move up and down along the chute, and during water level decreasing, the siphon ball-cock assembly 8 can decline with water level decreasing, water level
In uphill process, before water level rises to highest setting position, control floating ball 801 controls siphon ball-cock assembly 8 by floating ball rod
Relative motion does not occur with lower end siphon pipe, when water level rises to highest setting position, control floating ball 801 passes through floating ball rod band
Dynamic siphon ball-cock assembly 8 moves upwards control water outlet 701 and closes.The bottom of the siphon ball-cock assembly 8 is installed with buoyant member 802,
Buoyant member 802 can make siphon ball-cock assembly 8 have certain buoyancy, decline with the decline of water level.
