The limit structure is arranged on a gradually large opening at the lower end part of the water inlet drum and arranged on a gradually reducing opening at the top end of the balance buoyancy tank, and the gradually reducing opening is positioned on the outer side of the gradually large opening.

The outer circumference of balanced flotation tank evenly is provided with three flotation tank water diversion ports.

The cross section of the sealing ring is semicircular.

The top of the water inlet drum is provided with an access hole, and the access hole is provided with an access cover.

The invention has the beneficial effects that: the invention relates to a limit valve of a buoyancy tank, which is arranged in a water tank and a water pool and is used as a high liquid level stop valve. Its simple to operate only needs to link to each other water inlet and water tank water inlet pipe mouth and accomplishes the installation, drives balanced flotation tank through water buoyancy and closes the valve, need not the connecting rod, and occupation space is little, can set up in small-size water tank, and is equipped with three distributive port, and the passageway is big not the choked flow.

Detailed Description

The present invention is described in detail below with reference to the attached drawings.

As shown in fig. 1-6, a self-control buoyancy tank limiting valve comprises a water inlet barrel 4 and a balance buoyancy tank 2, wherein the top end of the inner cavity of the balance buoyancy tank 2 is open, the bottom end of the water inlet barrel 4 extends into the opening, a limiting structure used for limiting the bottom end of the water inlet barrel 4 to be separated from the opening is arranged between the balance buoyancy tank 2 and the water inlet barrel 4, a water inlet 1 is arranged on the side surface of the water inlet barrel 4, a buoyancy tank water diversion port 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 barrel 4 corresponding to the sealing bearing groove 8.

The water inlet 1 on the side of the water inlet drum 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 barrel 4 from the water inlet 1, falls into the balance buoyancy tank 2, and then flows into the water tank or the water pool through the water diversion port 10 of the buoyancy tank. 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 balance role, and the buoyancy tank can stably move up and down by adopting a tumbler and a ship bottom balance principle. Along with the rising of the water level, 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 along with the continuous rising of the water level, referring to fig. 2, finally, the seal bearing groove 8 of the balance buoyancy tank 2 is tightly attached to the seal ring 6 of the water inlet drum 4, the water diversion port 10 of the buoyancy tank is closed, at the moment, the water inlet is automatically closed, and the water tank does not enter water. When the water level of the water tank drops, the balance buoyancy tank 2 drops along with the drop of the water level, at the moment, the water diversion port 10 of the buoyancy tank is opened, and the water inlet 1 of the water tank enters water.

The invention is arranged on the water inlet pipe of the water tank and is positioned below the overflow water level, so that the water inlet can be automatically closed when the water level height of the water tank and the water tank reaches the highest upper limit water level, and the situation that water resources are wasted due to overflow of excessive water caused by ultrahigh water level can be avoided. The invention can ensure the safe water level of the water body, is particularly embodied in the water tank and the water pool of the basement, and ensures that the accident that the basement and the machine room are flooded due to the overflow caused by the overhigh water level of the water pool is avoided.

The limiting structure is a gradually large opening 5 arranged at the lower end part of the water inlet drum 4 and a gradually reducing opening 7 arranged at the top end of the balance buoyancy tank 2, and the gradually reducing opening 7 is positioned at the outer side of the gradually large opening 5. The sealing ring 6 is arranged on the lower end surface of the gradually enlarged opening 5. When the balance buoyancy tank 2 falls to a proper position, the tapered opening 7 is tightly attached to the outer surface of the tapered opening 5, and the water inlet drum 4 is limited from separating from the balance buoyancy tank 2.

The outer circumference of the balance buoyancy tank 2 is evenly provided with three buoyancy tank water distribution openings 10.

The cross section of the sealing ring 6 is semicircular and is made of high-quality silica gel materials.

The top of the water inlet drum 4 is provided with an access hole, the access hole is provided with an access cover 3, the access cover 3 is a sealing cover, and the access cover 3 is opened when the access cover needs to be overhauled.

Finally, it should be noted that the above-mentioned contents are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, and that the simple modifications or equivalent substitutions of the technical solutions of the present invention by those of ordinary skill in the art can be made without departing from the spirit and scope of the technical solutions of the present invention.
