Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as Figure 1-Figure 6 Shown, a kind of self-control buoyancy tank limit valve comprises water inlet drum 4 and balance buoyancy tank 2, the top opening of the inner chamber of balance buoyancy tank 2, the bottom end of water inlet drum 4 stretches in the opening, balance buoyancy tank 2 Between the tank 2 and the water inlet drum 4, there is a limit structure for restricting the bottom end of the water inlet drum 4 from leaving the opening. There is a water diversion port 10 of the buoyancy tank, and the bottom surface of the inner cavity of the balance buoyancy tank 2 is provided with an annular sealing groove 8, and the bottom surface of the water inlet drum 4 is provided with an annular sealing ring 6 corresponding to the sealing groove 8.

[0021] The water inlet 1 of water inlet cylinder 4 sides is connected with the water inlet pipe of water tank, ...

Abstract

The invention discloses a self-controlled buoyancy tank limiting valve. The self-controlled buoyancy tank limiting valve comprises a water inlet circular barrel and a balancing buoyancy tank, wherein an opening is formed in the top end of an inner cavity of the balancing buoyancy tank; the bottom end of the water inlet circular barrel extends into the opening; a limiting structure used for limiting the bottom end of the water inlet circular barrel from being separated from the opening is arranged between the balancing buoyancy tank and the water inlet circular barrel; a water inlet is formed in the side of the water inlet circular barrel; a buoyancy tank water distribution opening is formed in the side of the balancing buoyancy tank; an annular sealing and bearing groove is formed in the bottom surface of an inner cavity of the balancing buoyancy tank; and an annular sealing ring corresponding to the sealing and bearing groove is arranged on the bottom surface of the water inlet circular barrel. The self-controlled buoyancy tank limiting valve is mounted in a water tank and a water pool and serves as a high-liquid-level closing valve. The self-controlled buoyancy tank limiting valve is convenient to mount, can be mounted by only connecting the water inlet with a water inlet pipe opening of the water tank, drives the balancing buoyancy tank to turn off the valve through water buoyancy, is free of a connection rod, occupies small space, and can be used in a small water tank.

Description

technical field [0001] The invention relates to the technical field of self-control floating ball valves, in particular to a self-control floating tank limit valve. Background technique [0002] At present, the mechanical ball float valves commonly used in the market all have a ball float connecting rod structure, and the existing ball float valves have many disadvantages in the way of force transmission through the connecting rod. The floating ball connecting rod structure will occupy the space of the water tank, reducing the water volume of the water tank, and the larger the diameter of the water inlet pipe, the longer the floating ball connecting rod, the larger the space occupied, the more inconvenient the installation, and the less suitable for small water tanks. [0003] Therefore, there is an urgent need in the prior art for a self-control floating tank limit valve with reasonable structure, small footprint and easy installation. Contents of the invention [0004] ...
