[0001] This utility model relates to a valve, and more particularly to a two-stage float-type water control valve. Background Technology
[0002] With population growth and increasing demands from industry and agriculture, efficient water resource management has become increasingly important. Valves are therefore widely used in various water conservancy projects, such as urban water supply systems, irrigation projects, sewage treatment, and flood control, to ensure the control and regulation of water flow, thereby achieving the rational allocation and effective utilization of water resources and guaranteeing the safe and stable operation of water conservancy projects.
[0003] In existing technologies, valves are usually only used to regulate the opening and closing of pipelines, and cannot be effectively regulated in real time when the water supply is insufficient or the water source fluctuates greatly. This results in a poor water experience for customers and is prone to causing mechanical failures of water-using equipment.
[0004] Therefore, it is necessary to provide a two-stage float-controlled valve to solve the problems mentioned in the background art. Summary of the Invention
[0005] The purpose of this utility model is to provide a two-stage float-type water control valve. This valve, by setting a first control valve and a second control valve, can regulate and maintain a stable water supply at the outlet, thus avoiding damage to water-using equipment caused by fluctuations in the water supply.
[0006] The objective of this utility model is achieved through the following technical solution: A two-stage float-type water control valve includes: a housing; a second partition fixedly disposed within the housing, the second partition dividing the housing into a water guiding chamber and a water control chamber; a first partition fixedly disposed within the water control chamber, the first partition dividing the water control chamber into an inlet end and an outlet end; a filter screen disposed at the inlet end, and the inlet end communicating with the water guiding chamber via a first flow guide port; and a first control valve disposed at the outlet end, the first control valve being used to control the conduction state of the valve port. A second control valve is installed inside the water guide chamber, and the second control valve is connected to the water outlet through a second guide port.

[0009] As a further improvement of this utility model, the third partition divides the water guiding chamber into a water storage chamber and a connecting chamber, and the connecting chamber is connected to the water outlet through the second guide port.
[0010] As a further improvement of this utility model, both the first float and the second float are hollow spheres made of plastic.

[0015] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings.
[0016] like Figures 1 to 5 As shown, this utility model discloses a two-stage float-type water control valve, which includes: a housing 1, a second partition 9 fixedly disposed inside the housing 1, the second partition 9 dividing the housing 1 into a water guiding chamber 2 and a water control chamber 3, a first partition 4 fixedly disposed inside the water control chamber 3, the first partition 4 dividing the water control chamber 3 into an inlet end and an outlet end, a filter screen 5 disposed at the inlet end, and the inlet end and the water guiding chamber 2 being connected through a first guide port 8, and a first control valve 6 disposed at the outlet end, the first control valve 6 being used to control the conduction state of the valve port; A second control valve 7 is provided inside the water guide chamber 2, and the second control valve 7 is connected to the water outlet through the second guide port 10.
[0017] In operation, water enters the inlet and is filtered by the filter screen 5. The filtered water then enters the water guide chamber 2 through the first guide port 8. As the water in the water guide chamber 2 gradually increases, its buoyancy adjusts the second control valve 7. When the water depth in the water guide chamber 2 reaches the height limited by the second control valve 7, the second control valve 7 is opened under the action of buoyancy, allowing the water in the water guide chamber 2 to flow into the outlet through the second guide port 10.
[0018] As the water flows towards the outlet, the buoyancy of the water regulates the first control valve 6, thereby controlling the discharge of the water. When the water depth at the outlet reaches the height limited by the first control valve 6, the first control valve 6 connects the outlet to the outside, allowing the water to flow out for normal use by external equipment.
[0019] When the water supply is insufficient and cannot meet the minimum water usage conditions of the water-using equipment, the water source temporarily stored in the water guide chamber 2 and the water source temporarily stored at the outlet end will flow down to a height below the limit of the second control valve 7 and the first control valve 6. In this case, the second control valve 7 and the first control valve 6 will cut off the water source to prevent damage to external equipment due to insufficient water supply.
[0020] Meanwhile, even when the overall water supply is unstable but sufficient, the first control valve 6 and the second control valve 7 can be used to maintain a stable supply of water at the outlet, thus avoiding damage to water-using equipment caused by fluctuations in the water supply.
[0021] like Figure 4 As shown, the present invention also includes: the first control valve 6 includes an outlet 61, a valve plate 65 is slidably and sealingly disposed in the outlet 61, one end of a chain is fixedly disposed on the valve plate 65, the other end of the chain is connected to the first float 64, and a spring is disposed between the valve plate 65 and the outlet 61. The first limiting frame 62 has one end fixed to the water outlet 61 and the other end fixedly provided with a limiting ring 63; the first float 64 is movably disposed within the first limiting frame 62 and within the limiting ring 63.
[0022] The first float 64 changes its relative height within the first limiting frame 62 by buoyancy. When the height of the first float 64 changes, it pulls the valve plate 65 through the chain, thereby changing the relative position of the valve plate 65 within the outlet 61. When the water depth in the outlet reaches the maximum height adjusted by the first float 64, the first float 64 will move to the top of the first limiting frame 62, so that the valve plate 65 moves and the outlet 61 is opened, thereby supplying water to external equipment.
[0023] like Figure 5 As shown, the present invention also includes: the second control valve 7 includes a third partition 71, the third partition 71 is fixed in the water guide chamber 2, and a valve hole is also provided through the third partition 71, and a valve plug 73 is provided through the valve hole for sliding sealing. The second limiting bracket 72 is fixed on the valve port, and a sliding hole is provided on the second limiting bracket 72. A second float ball 74 is slidably disposed through the sliding hole, and the second float ball 74 is also fixedly connected to the valve plug 73.
[0024] like Figure 3 As shown, the present invention also includes: the third partition 71 divides the water guiding chamber 2 into a water storage chamber 21 and a connecting chamber 22, and the connecting chamber 22 is connected to the water outlet through the second guide port 10.
[0025] Both the first float 64 and the second float 74 are hollow spheres made of plastic.
[0026] After filtration, the water is temporarily stored in the water storage tank 21. The buoyancy generated at this time acts on the second float 74, which moves slowly under the action of buoyancy. When the water depth in the water storage tank 21 reaches a certain height, the buoyancy generated will cause the second float 74 to pull the valve plug 73, thereby opening the valve hole on the third partition 71, so that the water in the water storage tank 21 flows to the connecting tank 22, and the water in the connecting tank 22 flows to the outlet end through the second guide port 10.
