Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-6, an automatic control buoyancy tank limit valve comprises a water inlet circular barrel 4 and a balance buoyancy tank 2, wherein the top end of the inner cavity of the balance buoyancy tank 2 is opened, the bottom end of the water inlet circular barrel 4 stretches into the opening, a limit structure for limiting the bottom end of the water inlet circular barrel 4 to separate from the opening is arranged between the balance buoyancy tank 2 and the water inlet circular barrel 4, a water inlet 1 is arranged on the side surface of the water inlet circular barrel 4, a buoyancy tank water distribution opening 10 is arranged on the side surface of the balance buoyancy tank 2, an annular sealing bearing groove 8 is arranged on the bottom surface of the inner cavity of the balance buoyancy tank 2, and an annular sealing ring 6 is arranged on the bottom surface of the water inlet circular barrel 4 corresponding to the sealing bearing groove 8.
The water inlet 1 on the side surface of the water inlet barrel 4 is connected with the water inlet pipe of the water tank and the water pool. In operation, referring to fig. 1, water enters the water inlet drum 4 from the water inlet 1, falls into the balance buoyancy tank 2, and flows into the water tank or pool through the buoyancy tank water diversion port 10. The lower part of the balance buoyancy tank 2 is semicircular, the middle part of the lower end of the balance buoyancy tank 2 is provided with a balance base 9, the balance base 9 mainly plays a role in balance, and the buoyancy tank can stably move up and down by adopting the tumbler and ship bottom balance principle. As the water level rises, when the water level exceeds the height of the balance base 9, the balance buoyancy tank 2 stably floats upwards along with the rising of the water level, and as the water level continuously rises, the seal bearing groove 8 of the balance buoyancy tank 2 is tightly attached to the seal ring 6 of the water inlet round barrel 4, the buoyancy tank water diversion port 10 is closed, at the moment, water inlet is automatically closed, and the water tank is not in water inlet. When the water level of the water tank falls, the balance buoyancy tank 2 falls along with the falling water level, at the moment, the buoyancy tank water diversion port 10 is opened, and the water inlet 1 of the water tank is filled with water.
The utility model is arranged on the water inlet pipe of the water tank and is positioned below the overflow water level, and can automatically close the water inlet when the water level of the water tank and the water tank reaches the highest upper limit water level, so that the situation that excessive water overflows due to the ultrahigh water level and water resources are wasted can not occur. The utility model can ensure the safe water level of the water body, is particularly embodied in a basement water tank and a pool, and ensures that accidents of flooding the basement and a machine room caused by the ultrahigh overflow of the water level of the pool are avoided.
