Example 1

As shown in fig. 1-2, an intelligent float valve is disclosed, wherein the intelligent float valve comprises a float valve, a float valve pipeline is connected with a water storage device, the float valve comprises a valve main body 1 and a float ball device 5 for detecting the water level height of the water storage device; the valve body 1 comprises a water inlet end 2, a water outlet end 3, an upper cavity 4 and a valve core for adjusting the opening of the float valve according to the water pressure of the water inlet end and the upper cavity; the float valve also comprises a diversion waterway for adjusting the water level of the water storage device, and the float device 5 is arranged on the diversion waterway.

In this embodiment, the water storage device is supplied with water by the ball float valve and the diversion waterway, and the floating ball 50 arranged in the water storage device rises synchronously with the liquid level during the water supply. The float device 5 comprises a float 50 arranged in the water storage device, a connecting rod 51 and a float switch 52, wherein the float 50 is connected with the float switch 52 through the connecting rod 51 so as to control the on or off of the float switch 52. The floating ball 50 may be provided on the mounting rod and may be moved up and down along the mounting rod. With continuous water filling, the water level of the water storage device is higher and higher, and the position of the floating ball 50 is also higher and higher. During the rising of the float 50, the float switch 52 will be gradually closed under the action of the link 51. When the liquid level of the water storage device reaches the requirement, the float switch 52 is completely closed, and the diversion waterway can not supplement water to the water storage device. And when the float switch 52 is closed, the pressure of the water inlet end 2 of the float valve is consistent with the pressure of the upper cavity 4, the float valve is closed under the action of the valve core, and water cannot enter the water storage device through the float valve body. Over time, the liquid level in the water storage device will drop and change due to consumption and the like, and the height of the floating ball 50 will drop. At this time, the diversion waterway and the ball float valve are conducted, so that water is continuously supplied to the water storage device, the liquid level of the water storage device is lifted to the appointed liquid level, and the water storage device circulates in sequence, so that the accurate control of the liquid level in the water storage device is realized.

The opening degree of the float valve is controlled through the valve core, when the water pressure of the water inlet end 2 of the float valve is suddenly changed, the float valve cannot be rapidly opened or closed due to the sudden change of the water pressure of the water inlet end 2, and therefore a good pressure stabilizing effect can be achieved.

The principle of the diversion waterway is as follows: the floating ball 50 moves correspondingly along with the fluctuation of the liquid level of the water storage device, and the floating ball 50 completes the opening or closing of the floating ball switch 52 under the action of the connecting rod 51 in the moving process. When the actual liquid level is lower than the required value, the diversion waterway is conducted, water flow can enter the diversion waterway from the water inlet end 2 of the float valve, and the water flow can enter the water storage device from the water outlet end 3 of the float valve through the pipeline of the diversion waterway, or the water flow is discharged. Thereby realizing the water supplementing of the water storage device and improving the liquid level of the water storage device. When the position of the floating ball 50 reaches the required value again, the floating ball switch 52 is closed under the action of the connecting rod 51, water in the diversion waterway cannot enter the water storage device, and after the floating ball switch 52 is closed, the pressure of the water inlet end 2 of the floating ball valve is consistent with that of the upper cavity 4, at the moment, the floating ball valve is also closed under the action of the valve core, and at the moment, water cannot enter the water storage device through the floating ball valve body 1.

The difference between this embodiment and embodiment 1 is that: the diversion waterway comprises a first diversion waterway and a second diversion waterway. The water inlet end of the first diversion waterway is connected with the water inlet end 2 of the float valve, the water outlet end of the first diversion waterway is connected with the upper cavity 4 of the float valve, water is supplied to the upper cavity 4 of the float valve through the first diversion waterway, so that upper cavity water pressure is provided for the upper cavity 4, and the valve core adjusts the valve core of the opening degree of the float valve under the action of the water pressure of the water inlet end 2 and the upper cavity water pressure. The valve core can also adopt a diaphragm or valve clack structure, the interception effect is realized through the action of a spring, when the upper cavity pressure of the float valve is greater than the elastic force of the spring, the valve core moves under the action of water pressure, so that the float valve can conduct running water, and when the upper cavity pressure of the float valve is less than the elastic force of the spring, the valve core is completely propped up, thereby intercepting.

The first diversion waterway is sequentially provided with a gate valve 6, a check valve 7, a Y-shaped filter 8 and a needle valve 9, and a pressure gauge 10 can be arranged on the first diversion waterway, and the pressure gauge 10 is arranged between the gate valve 6 and the check valve 7. The water pressure is monitored at any time by the pressure gauge 10.

The water inlet end of the second diversion waterway is connected with the water inlet end 2 of the float valve, and the water outlet end of the second diversion waterway is connected with the water outlet end 3 of the float valve or the water outlet end behind the float valve. The floating ball device 5 is arranged in the second diversion waterway. The floating ball device 5 is arranged in the second diversion waterway, and the floating ball 50 rises or falls along with the liquid level of the water storage device, so that the conduction or the closing of the second diversion waterway is controlled, and the accurate adjustment of the liquid level in the water storage device is realized. The second diversion water path specifically comprises a gate valve 6, a check valve 7, a Y-shaped filter 8, a floating ball device 5 and a pressure relief pilot valve 11. The first diversion waterway and the second diversion waterway share pipelines provided with a gate valve 6, a check valve 7 and a Y-shaped filter 8.

The pressure relief pilot valve 11 can also be connected with a main pipeline, and when the main pipeline pressure is lower than a set value (the pressure is set by adjusting the adjusting nut), the opening of the pressure relief pilot valve 11 is reduced. At this time, the opening of the main valve is reduced with the pressure difference between the inlet and the outlet of the pressure relief pilot valve 11.

Example 3

As shown in fig. 3, an intelligent float valve is disclosed, wherein the intelligent float valve comprises a float valve, a float valve pipeline is connected with a water storage device, the float valve comprises a valve main body 1 and a float ball device 5 for detecting the water level height of the water storage device; the valve body 1 comprises a water inlet end 2, a water outlet end 3, an upper cavity 4 and a valve core for adjusting the opening of the float valve according to the water pressure of the water inlet end and the upper cavity; the float valve also comprises a diversion waterway for adjusting the water level of the water storage device, and the float device 5 is arranged on the diversion waterway.

The difference between this embodiment and the above embodiment is that: the water storage device is internally provided with a water seepage sleeve, and the floating ball 50 is arranged in the water seepage sleeve 53. It is easy to understand that when water is directly supplied to the water storage device through the ball float valve or water is injected into the water storage device through the diversion waterway, the liquid level of the water storage device fluctuates up and down, and then the floating ball 50 floating on the liquid level also fluctuates up and down along with the fluctuation of the liquid level. In this state, the height of the float 50 is then in error with the actual liquid level.

Therefore, in order to avoid the floating ball 50 floating up and down due to the fluctuation of the liquid level in the water injection process of the water storage device, so as to influence the judgment of the liquid level, a water seepage sleeve 53 capable of seepage water can be arranged in the water storage device, and the floating ball 50 is arranged in the water seepage sleeve 53. Through this design, when water storage device is at the water injection or the process of draining, the liquid level is undulant, and the outer wall of infiltration sleeve 53 can play fine anti-fluctuation effect to make the liquid level in the infiltration sleeve 53 steadily rise, avoided floater 50 undulant along with the liquid level, thereby make through floater 50 to the detection of liquid level height more accurate.

The water seepage sleeve 53 can be a hollow pipe, and then a plurality of water seepage holes are formed in the side wall of the hollow pipe, water in the water storage device enters the hollow pipe through the water seepage holes, and under the principle of communicating vessels, the actual liquid level of the hollow pipe is guaranteed to be consistent with the liquid level of the water storage device. Meanwhile, in order to facilitate the installation of the water penetration sleeve 53, the water penetration sleeve 53 may be connected with the inner wall of the water storage device.
