Description

Technical Field

[0001] This application relates to the field of valve technology, and in particular to a time-controlled hydraulic dual-level controller. Background Technology

[0002] A remote-controlled float valve (or hydraulic sensor float valve) is a level control valve. Its function is to control the water level in a pool (or tank). When the water level falls below a set level, the remote-controlled float valve opens to allow water to enter the pool (or tank). When the set water level is reached, the remote-controlled float valve closes to stop water flow. Remote-controlled float valves feature automatic opening and closing and are widely used in industries such as construction, water conservancy, hydropower, and water supply. However, the following problems with remote-controlled float valves currently on the market need to be addressed:

[0003] 1. When the water level in the pool (or tank) drops slightly, the remote-controlled float valve opens, allowing water to enter the pool (or tank). When the water level rises to the set level, the remote-controlled float valve closes. This frequent opening and closing of the remote-controlled float valve, sometimes as many as 50-60 times or more per day, leads to fatigue and shortens its lifespan. Furthermore, the float in the pilot valve is easily affected by water waves in the pool (or tank), making it prone to failure. This can cause a large amount of water to overflow, and in severe cases, flood the pump room.

[0004] 2. Remote-controlled float valves can only control the high water level in the pool (or tank). This can easily lead to the water in the pool (tank) aging too long, causing water quality deterioration and affecting health.

[0005] 3. Since the remote control float valve can only control the high water level of the pool (or tank), the pool (or tank) is always full, and the volume of the pool (or tank) cannot be fully utilized. Utility Model Content

[0006] The purpose of this application is to provide a time-controlled hydraulic dual-level controller that stops water intake when the water level is high and starts water intake when the water level is low, and the water intake time can be set arbitrarily when needed.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] This application provides a time-controlled hydraulic dual-level controller, including an inlet pipe connected to an external water source, which injects water into a water storage device. An inlet main valve is installed on the inlet pipe and connected to a control pilot valve, which is installed in a control water tank. The control pilot valve controls the inlet main valve by controlling changes in the water level within the control water tank. A siphon pipe is also installed in the control water tank. The control water tank is connected to the water storage device via a connecting pipe, with one end of the siphon pipe located inside the control water tank and the other end inside the connecting pipe. The control water tank is also connected to a solenoid valve via a pipe. The solenoid valve is connected to a time-controlled switch, which controls the opening and closing of the solenoid valve. Together with the siphon pipe, this controller achieves dual-level control of the water storage device.

[0009] The control water tank is equipped with a partition that divides the control water tank into a static water tank and a dynamic water tank. The static water tank is equipped with a float that is connected to a linkage mechanism, which is connected to a control valve.

[0010] One end of the solenoid valve is connected to the control water tank via a connecting pipe, and the other end is connected to a connecting pipe.

[0011] The opening of the connecting pipe is located at the bottom of the still water tank.

[0012] The upper port of the connecting pipe is located at the bottom of the moving water tank.

[0013] The lower port of the connecting pipe is located at the bottom of the water storage device.

[0014] The water storage device is a water storage pool or water storage tank.

[0015] Compared with existing technologies, the advantages of this application are: it greatly reduces the number of times the main valve and control pilot valve are opened, thus extending their service life; the low water level can be set arbitrarily, ensuring the circulation of water in the pool (or tank) and shortening the water age; and the time control switch can be set arbitrarily for easy regulation.

[0019] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0020] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0021] like Figure 1 and Figure 2 As shown, a time-controlled hydraulic dual-level controller includes an inlet pipe connected to an external water source, which injects water into a water storage device 4. An inlet main valve 1 is installed on the inlet pipe, and the inlet main valve 1 is connected to a control pilot valve 3. The control pilot valve 3 is installed in a control water tank 2. Changes in the water level in the control water tank 2 cause the control pilot valve 3 to control the inlet main valve 1. A siphon pipe 5 is also installed in the control water tank 2. The control water tank 2 and the water storage device 4 are connected via a connecting pipe 8. One end of the siphon pipe 5 is located in the control water tank 2, and the other end is located in the connecting pipe 8. The control water tank 2 is also connected to a solenoid valve 7 via a pipe. The solenoid valve 7 is connected to a time-controlled switch 6, which controls the opening and closing of the solenoid valve 7. Together with the siphon pipe 5, the controller achieves dual-level control of the water storage device 4.

[0022] The control water tank 2 is provided with a partition 20, which divides the control water tank 2 into a static water tank 21 and a dynamic water tank 22. The static water tank 21 is provided with a float 23, which is connected to a linkage mechanism 24. The linkage mechanism 24 is connected to a control valve 3.

[0023] One end of the solenoid valve 7 is connected to the control water tank 2 via a connecting pipe, and the other end is connected to the connecting pipe 8.

[0024] The opening of the connecting pipe is located at the bottom of the still water tank 21.

[0025] The upper port of the connecting pipe 8 is located at the bottom of the moving water tank 22.

[0026] The lower port of the connecting pipe 8 is located at the bottom of the water storage device 4.

[0027] The water storage device 4 is a water storage pool or water storage tank.

[0028] The water intake process of the control water tank 2 is as follows: As the water level in the storage device (4) rises, water will rise from the bottom connecting pipe 8 of the control water tank to the moving water tank 22 of the control water tank 2, and then overflow the intermediate partition 20 into the static water tank 21 of the control water tank 2 until the float 23 floats up. At this time, the control pilot valve 3 is closed, the main inlet valve 1 is closed, the storage device 4 stops water intake, and the water level is at the highest level. When the water level of the storage device 4 drops, the static water tank 21 of the control water tank 2, which contains the control pilot valve float 23, will not have its water level drop with the water level of the storage device 4 because the bottom sealing solenoid valve 7 is in the closed state. Therefore, the float will still float up, the control pilot valve 3 will be closed, and the main inlet valve 1 will be closed. The storage device 4 will not take in water. As the water level in storage device 4 continues to drop, when the water level in storage device 4 reaches the designed low water level, a siphon phenomenon occurs. Water in the static water tank 21, which contains the float 23, is drawn out by the siphon pipe 5. The float 23 falls, the control pilot valve 3 opens, and the main inlet valve 1 opens, allowing water to enter storage device 4. When the water level in storage device 4 is between the high and low water levels, a time period can be set in the time control switch 6 as needed. During this period, the solenoid valve 7 is in the open state, the water level in the static water tank 21 drops, the float 23 falls, the control pilot valve 3 opens, the main inlet valve 1 opens, water enters storage device 4, and the water level rises to the highest water level.

[0029] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
