Description

Sinking-floating type automatic water-replenishing ball valve

Technical Field

The invention relates to automatic water replenishing equipment for a water tank, in particular to an automatic water replenishing ball valve which can be normally used under various water pressure conditions, and belongs to the field of automatic water replenishing equipment.

Background

In daily production life of people, various automatic water replenishing devices can not be left everywhere in cities or rural areas, in factories, hospitals, kitchens and restaurants, for example, containers such as various water storage tanks, toilet water tanks and the like which are common in daily life of people can not be left. From the appearance, these automatic water supply equipment can be said to be various, and the diverse, but can mainly be divided into two main categories from the functional structure, promptly: a piston type hydraulic water level control valve and a lever type automatic water-replenishing ball valve.

The piston type hydraulic water level control valve mainly comprises a valve body, a piston, a floating ball, a lever and the like, and the working principle is that when the water level in a water pool or a water tank drops to exceed a preset value and goes off-line, the floating ball in a floating cavity falls to drive the lever to open a pilot hole of the control valve, an air hole leading to an upper cavity of the piston is opened under the action of water pressure in a pipeline, the pressure of the upper cavity of the piston is reduced, a pressure difference is formed between the upper part and the lower part of the piston, and the piston is opened under; when the water level rises to a preset value and reaches the upper line, the floating ball rises to drive the lever to close the pilot hole of the control valve, the pressure of the upper cavity of the piston is continuously increased, and when the pressure of the upper cavity of the piston is greater than the pressure of water supplied by the water pipe, the piston is closed to stop water supplement, so that the automatic water supplement function is realized in a reciprocating manner. Therefore, although the piston type hydraulic water level control valve has the advantages of small volume, large water yield, high water replenishing speed and the like, the piston is opened by hydraulic pressure to supply water according to the working principle, so that the application range of the piston type hydraulic water level control valve can be limited to be used only under the condition of large water pressure in a water supply pipeline, and otherwise, normal automatic water replenishing cannot be realized.

The lever-type automatic water-replenishing ball valve mainly consists of valve body, floating ball, connecting rod, crank arm and piston. The working principle is simple, namely a floating ball moves up and down along with the water level to drive a connecting rod and a crank arm to push and pull a piston in a valve body, so that the piston of the automatic water replenishing ball valve is opened and closed. When the water level of the water tank drops, the floating ball drives the connecting rod and the crank arm to pull the piston in the valve body outwards to open the water outlet of the water replenishing ball valve for water replenishing; when the water level rises, the floating ball drives the connecting rod and the crank arm to push and press the piston in the valve body inwards until the water replenishing of the water outlet of the water replenishing ball valve is completely closed and the water replenishing is stopped. The lever type automatic water replenishing ball valve has the advantages of simple structure, low production cost and the like, but the working principle of the lever type automatic water replenishing ball valve is that a piston is pushed and pulled by utilizing a lever to achieve the purpose of opening and closing the water replenishing ball valve, so that the lever type automatic water replenishing ball valve is more suitable for being used on a pipeline with lower water pressure in a water supply pipe, and otherwise, the problems of untight closing, failure of automatic water replenishing and the like can occur; in addition, lever automatic water supply ball valve still exists: firstly, the delivery port is less, and moisturizing speed is slow, otherwise just must further increase extension floater and connecting rod volume and length, secondly when the water level in the water tank is close the water level stop line, the internal and external thrust size that acts on the piston is in the game state, needs the long time just can really realize automatic water supply and stop completely.

In summary, although the piston type hydraulic water level control valve and the lever type automatic water replenishing ball valve are two types of automatic water replenishing equipment which are most widely used at present, due to the functional structure defects of the piston type hydraulic water level control valve and the lever type automatic water replenishing ball valve, the requirements of people for normal use under different pressure water supply pipelines are difficult to meet, and particularly, when an automatic water replenishing container is produced, a manufacturer is difficult to select automatic water replenishing equipment which is suitable for normal use under various water pressure conditions, such as a common toilet water tank, and the manufacturer is difficult to find the automatic water replenishing equipment which is suitable for normal use on various water supply pipelines with different water pressures; therefore, the invention provides the automatic water replenishing equipment which is reasonable in structure, simple to install, convenient to use, fast and efficient, and solves the problem to be solved at present.
