Description
Technical Field
The present invention relates to a liquid level control container.
Background
Existing adjustable dual level depth controllers are often implemented using pumps (or solenoid valves) and associated control circuitry. For example, an electronic dual-liquid-level controller has higher liquid level control precision, but has a complex structure, and the whole controller has higher cost, lower power consumption and lower reliability due to the existence of a circuit.
Disclosure of Invention
It is an object of the present invention to provide an adjustable dual level controller that can eliminate the need for circuit control.
The technical scheme of the invention is as follows: a double-liquid-level controller comprises a liquid container, a control container positioned in the liquid container, and a liquid container communicated with the bottom of the control container; an exhaust float valve for exhausting air in the control container is arranged between the liquid container and the control container, an air inlet of the exhaust float valve is connected with the side wall of the control container, and a liquid outlet is arranged on the side wall of the liquid container; the control container is internally provided with an adjustable high-liquid-level control floating ball valve, and a liquid inlet of the high-liquid-level control floating ball valve with an adjustable position is connected with external liquid through the side wall of the control container.
Preferably, the liquid outlet is arranged at the lower part of the liquid container.
Preferably, the exhaust float valve is provided at an upper portion of a side wall of the control container.
When the liquid level controller works, the high liquid level control float valve with adjustable position is used for controlling the opening and closing of the liquid inlet valve of liquid, and when the liquid level reaches a high liquid level line, the liquid inlet valve is closed; under the state of high liquid level, the control container is matched with the exhaust ball valve, the liquid level falling process is started after the liquid level is high, the exhaust ball valve is in a closed state very quickly, the air in the upper part of the control container is reduced due to the fact that liquid in the lower part of the control container is discharged, the liquid in the control container stops flowing out of the bottom of the control container, and accordingly the adjustable high-liquid-level control ball valve is kept in the closed state until the water level of the liquid containing container is lower than the lower edge of the control container, and the closing state of the liquid inlet valve is relieved after a large amount of water in the control container flows out due to the fact that external air enters from the lower part of the control container, the liquid inlet valve is opened again, the liquid is discharged from the lower position to the higher position, the above processes are repeated, and the effect of controlling the high liquid level of the liquid outlet is achieved.
Compared with the prior art, the invention has the beneficial effects that: (1) The controller completely adopts a mechanical structure, has a simple and easy-to-realize structure, does not need electricity in use, does not need a relatively expensive electromagnetic valve or water pump, a matched control system, a water level sensor and the like, and is energy-saving, environment-friendly, safe and reliable. And (2) no electric drive is adopted, so that the safety is high. (3) The structure is simple, the abrasion is less in use, only the sealing material of the liquid inlet of the floating ball is aged (or worn) and the rotating shaft part of the valve body is worn for years, and the service life is long and the reliability is high.
Drawings
FIG. 1 is a schematic top view of a dual level controller according to the present invention.
Detailed Description
The present invention will be described in detail with reference to specific embodiments thereof so that the above objects, features and advantages of the present invention can be more clearly understood.
As shown in fig. 1, in this embodiment, the dual-liquid level controller is composed of a liquid container 1 and a control container 2, wherein the control container 2 is inversely buckled in the liquid container 1, and one side wall of the two is close to each other; an exhaust float valve 3 is arranged between the liquid container 1 and the control container 2, and an air inlet of the exhaust float valve 3 is connected with the side wall of the control container 3 and extends into the control container 2. An adjustable high-liquid-level control ball float valve 4 is arranged in the control container 2, a liquid inlet 41 of the ball float valve 4 penetrates through the side wall of the control container and the side wall of the liquid container 1 to be connected with an external liquid input pipeline, and a liquid outlet 11 is arranged at the bottom of the side wall of the liquid container 1. Typically, a vent ball float valve is provided in the upper portion of the control vessel.
When the liquid filling device works, firstly, the liquid inlet is opened, liquid is filled into the control container, and the liquid can directly flow into the liquid container due to the fact that the bottom of the control container is communicated with the liquid container. When the liquid level in the liquid container is slowly increased to cover the communication port between the internal control container and the liquid container, the air in the control container is in a closed state, so that fluid is limited to enter the control container, the adjustable high-liquid-level control float valve is larger in valve opening degree because the ball body is at a lower position, external liquid is faster than a ball valve used in daily life, after the liquid level in the liquid container is continuously increased to a certain height, the sealing ball body of the air-discharging float valve is immersed in the liquid, the ball valve floats upwards, the air in the control container is discharged from the air port of the air-discharging float valve, the liquid quickly enters the control container, the floating ball body of the adjustable high-liquid-level control float valve floats upwards, the high-liquid-level control float valve floats to close the liquid inlet, and the air-discharging float valve floats to keep the air inlet open; when the liquid in the liquid container is discharged, the liquid level descending process starts after the liquid level is high, the air exhaust ball valve is in a closed state quickly, the air quantity of the upper part of the control container is reduced due to the liquid discharge at the lower part of the control container, and when the liquid in the liquid container is continuously discharged, the liquid in the control container is finally stopped from flowing out of the bottom of the control container, and the liquid level in the liquid control container is higher at the moment, so that the adjustable high-liquid-level control ball valve is kept in the closed state until the water level of the liquid container is lower than the lower edge of the control container, and the closed state of the liquid inlet valve is released after the water in the control container flows out due to the fact that the external air enters from the lower part of the control container; after which a new level cycle is started again, and dual level control is thus cycled.
The liquid level control container can be used for plant irrigation, accurately controls the irrigation water level of plants, enables the plants to grow to obtain good water and gas conditions, is very beneficial to the growth of the plants, can save a large amount of water resources, and saves manpower and material resources.
When the control container is used, the low liquid level of the liquid is controlled by the placing height of the liquid container and the distance between the lower edge of the control container and the liquid container; the high liquid level of the liquid is regulated by an adjustable high liquid level control float valve and an adjustable exhaust valve are mutually matched and controlled.
The foregoing examples merely illustrate embodiments of the invention and are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
