Description

Technical Field

[0001] This utility model belongs to the field of water storage systems, and particularly relates to water supply devices and water storage systems. Background Technology

[0002] In large industrial parks, both production and living areas generally need to be equipped with water storage facilities to ensure sufficient water storage for daily production and living needs in the event of municipal water supply failure. If space is limited, the water storage tank often needs to adopt a fully underground structure, that is, the entire water storage tank structure is below the ground level, and the above ground level is used for other functions. At the same time, the water replenishment and water supply equipment rooms also need to be set below the ground level to ensure normal water storage and water supply needs.

[0003] In existing water storage systems, water inlet pipes are typically used for rapid water replenishment. To control the amount of water replenished, traditional solutions involve installing electric water replenishment valves in series on the inlet pipes. However, the electric actuators of these valves have a high annual failure rate in humid and dusty environments. They are prone to malfunctions such as short circuits caused by moisture on the circuit board, drift of the position sensor, and burnout of the motor due to overload, which can lead to the valve being fully opened or incorrect feedback on the opening degree, resulting in uncontrolled water replenishment. Excessive water replenishment can cause the water tank to overflow, resulting in water waste and even flooding of the equipment room, posing a serious safety hazard. Utility Model Content

[0004] The purpose of this application is to provide a water supply device and a water storage system, aiming to solve the problem of how to improve the safety and applicability of the water supply device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a water supply device is provided, comprising a water storage container having a receiving cavity, a first water inlet pipe for supplying water to the water storage container, a second water inlet pipe for supplying water to the water storage container, a gate valve disposed on the first water inlet pipe, and a flow control valve disposed on the second water inlet pipe. The inlet ends of the first water inlet pipe and the second water inlet pipe are connected to an external water source, and the outlet ends of the first water inlet pipe and the outlet ends of the second water inlet pipe are connected to the receiving cavity. The flow control valve is used to control the fluid flow rate of the second water inlet pipe, and the gate valve has a first state of opening the first water inlet pipe and a second state of disconnecting the first water inlet pipe.

[0007] In some embodiments, the inlet end of the second inlet pipe is connected between the external water source and the gate valve, and the outlet end of the second inlet pipe is connected between the water storage container and the gate valve.

[0008] In some embodiments, the inner diameter of the second water inlet pipe is smaller than the inner diameter of the first water inlet pipe.

[0009] In some embodiments, the inner diameter of the second water inlet pipe is in the range of 50mm to 150mm, and the inner diameter of the first water inlet pipe is in the range of 150mm to 250mm.

[0010] In some embodiments, the water supply device further includes a water replenishment valve, wherein the outlet end of the first water inlet pipe and the outlet end of the second water inlet pipe are connected to the receiving cavity through the water replenishment valve, and the water replenishment valve is used to control its on / off state according to the liquid level in the receiving cavity.

[0011] In some embodiments, a water meter is also provided between the outlet end of the second water inlet pipe and the water supply valve, and the water meter is used to display water consumption data.

[0012] In some embodiments, the water supply device further includes a water outlet pipe communicating with the receiving cavity and a water pump disposed on the water outlet pipe, the water pump being used to drive the liquid in the receiving cavity to be discharged to the outside of the water storage container through the water outlet pipe.

[0013] In some embodiments, the water storage container includes a top wall located above the liquid level in the containment cavity and an overflow outlet disposed on the top wall and communicating with the containment cavity, the overflow outlet being used to allow liquid in the containment cavity to overflow.

[0014] In some embodiments, the flow control valve is a ball valve, an eccentric butterfly valve, a diaphragm valve, or a plug valve.

[0015] Secondly, a water storage system is provided, which includes the water supply device described above.

[0016] The beneficial effects of this application are as follows: When the water supply device of this application is in use, the gate valve is switched to the second state during daily use. At this time, the gate valve disconnects the first water inlet pipe, so that the external water source can only supply water to the water storage container through the second water inlet pipe. Moreover, the flow control valve can control the fluid flow of the second water inlet pipe, thereby achieving precise control of the water supply to the water storage container, preventing safety hazards caused by excessive water replenishment, and effectively improving safety. When it is necessary to quickly replenish the water in the water storage container, the gate valve can be switched to the first state. At this time, the gate valve opens the first water inlet pipe, so that the first water inlet pipe supplies water to the water storage container. Thus, different water supply modes can be switched according to different water supply conditions, improving the applicability of the water supply device. Attached Figure Description

[0027] Please see Figures 1 to 3 This application provides a water supply device, including a water storage container 30 with a receiving cavity 200, a first water inlet pipe 10 for supplying water to the water storage container 30, a second water inlet pipe 20 for supplying water to the water storage container 30, a gate valve 40 disposed on the first water inlet pipe 10, and a flow control valve 50 disposed on the second water inlet pipe 20. The water inlet end of the first water inlet pipe 10 and the water inlet end of the second water inlet pipe 20 are connected to an external water source, and the water outlet end of the first water inlet pipe 10 and the water outlet end of the second water inlet pipe 20 are connected to the receiving cavity 200. The flow control valve 50 is used to control the fluid flow rate of the second water inlet pipe 20, and the gate valve 40 has a first state of opening the first water inlet pipe 10 and a second state of disconnecting the first water inlet pipe 10.

[0028] In this embodiment, the water storage container 30 is a water tank, water trough, or water pool, etc., used for storing water. Taking a water pool as an example, the water pool can adopt a fully underground structure, that is, the entire water pool is below the ground level, and the area above the ground level is used for other functions. At the same time, the water supply equipment room also needs to be set below the ground level and adjacent to the water pool to ensure normal water storage and supply needs. The first water inlet pipe 10, the second water inlet pipe 20, the gate valve 40, and the flow control valve 50 are located in the water supply equipment room.

[0029] It should be noted that in this embodiment, the gate valve 40 can be switched to the first state of connecting the first water inlet pipe 10 or the second state of disconnecting the first water inlet pipe 10 according to the actual situation. Specifically, the gate valve 40 is always in the second state during normal use. However, in some emergencies, such as when the external municipal water supply network or the internal pipe network of the industrial park fails and causes a long period of no water supply, the water in the water storage container 30 will gradually decrease or even be completely used up. When the municipal water supply or the internal pipe network resumes water supply, it is necessary to quickly replenish the water in the water storage container 30. At this time, the gate valve 40 is switched to the first state so that it can be filled with water in the shortest time. After the water storage container 30 is full, it is immediately switched to the second state.

[0030] Understandably, when the gate valve 40 is switched to the first state, both the first inlet pipe 10 and the second inlet pipe 20 are open, enabling rapid water replenishment; while when the gate valve 40 is switched to the second state, the gate valve 40 blocks the water flow to the first inlet pipe 10, so that the external water source can only supply water to the water storage container 30 through the second inlet pipe 20, and the flow control valve 50 can control the fluid flow of the second inlet pipe 20, thereby enabling long-term low-flow water replenishment.

[0031] When the water supply device of this application is in use, during normal use, the gate valve 40 is switched to the second state. At this time, the gate valve 40 disconnects the first water inlet pipe 10, so that the external water source can only supply water to the water storage container 30 through the second water inlet pipe 20. The flow control valve 50 can control the fluid flow of the second water inlet pipe 20, thereby achieving precise control of the water supply to the water storage container 30, preventing safety hazards caused by excessive water replenishment, and effectively improving safety. When it is necessary to quickly replenish the water in the water storage container 30, the gate valve 40 can be switched to the first state. At this time, the gate valve 40 opens the first water inlet pipe 10, so that the first water inlet pipe 10 supplies water to the water storage container 30. Thus, different water supply modes can be switched according to different water supply conditions, improving the applicability of the water supply device.

[0032] In some embodiments, such as Figure 2As shown, the water supply device also includes a water replenishment valve 60. The outlet ends of the first water inlet pipe 10 and the second water inlet pipe 20 are connected to the receiving cavity 200 through the water replenishment valve 60. The water replenishment valve 60 is used to control its on / off state according to the liquid level in the receiving cavity 200. By setting the water replenishment valve 60, when the liquid level in the receiving cavity 200 is high, the water replenishment valve 60 is closed, and water supply to the water storage container 30 is stopped. When the liquid level in the receiving cavity 200 is low, the water replenishment valve 60 is open, and water can be supplied to the water storage container 30, thereby realizing automatic water supply to the water storage container 30 and reducing manual intervention.

[0033] In some embodiments, a water meter 90 is also provided between the outlet end of the second water inlet pipe 20 and the water supply valve 60. The water meter 90 is used to display water consumption data. Understandably, the water meter 90 is equipped with a screen, and the water consumption data is displayed on the screen, making it convenient for operators to intuitively understand the amount of water consumption data, thereby facilitating adjustments by the operators.

[0034] It should be noted that the flow control valve 50 is normally in the open water supply state. The water supply rate depends on the opening degree of the flow control valve 50, which is determined by the daily water consumption reading of the water meter 90. Specifically, the opening degree of the flow control valve 50 can be set to the maximum daily water consumption of the month, ensuring that the monthly water supply is slightly greater than the actual monthly water consumption. The balance between the daily water supply and water consumption is regulated by the sufficient capacity of the water storage container 30. When the water consumption is greater than the water supply, the water level in the water storage container 30 is slightly lower, and the water supply valve 60 is in the constant water supply state. When the water supply exceeds the water consumption, the water supply valve 60 automatically closes, stopping the water supply.

[0035] When the water supply valve 60 fails due to a malfunction and continuously supplies water, the water supply volume is set to be only slightly greater than the water consumption. This will prevent the water storage container 30 from overflowing in a short time, or even if water overflows, it will not cause the water pump 72 to be flooded. This is because the flow rate of the submersible pump used for drainage is much greater than the amount of overflowing water, thus achieving the purpose of preventing the water pump 72 from being flooded by overflow.

[0036] In some embodiments, such as Figure 2 As shown, the inlet end of the second inlet pipe 20 is connected between the external water source and the gate valve 40, and the outlet end of the second inlet pipe 20 is connected between the water storage container 30 and the gate valve 40. That is to say, at this time, the flow control valve 50 in the second inlet pipe 20 is connected in parallel with the gate valve 40 of the first inlet pipe 10. This can reduce the length of the second inlet pipe 20, thereby reducing the length of the entire water storage system pipeline, which is beneficial to saving costs.

[0037] In some embodiments, the inner diameter of the second water inlet pipe 20 is smaller than the inner diameter of the first water inlet pipe 10. By setting the second water inlet pipe 20 to have a smaller inner diameter, the flow rate of water is further reduced when the second water inlet pipe 20 supplies water alone, thereby reducing the water intake and further improving the safety of the water supply device; while by setting the first water inlet pipe 10 to have a larger inner diameter, the flow rate of water is increased when a large amount of water is needed, thereby improving the water supply efficiency.

[0038] Optionally, the inner diameter of the second inlet pipe 20 ranges from 50mm to 150mm, and the inner diameter of the first inlet pipe 10 ranges from 150mm to 250mm. The inner diameter of the second inlet pipe 20 cannot be too small, as this would significantly reduce the water flow velocity, thereby reducing water supply efficiency and failing to meet normal water supply needs. Conversely, the inner diameter of the second inlet pipe 20 cannot be too large, as this would increase the water flow velocity, making it impossible to accurately control the water supply. Optionally, the inner diameter of the second inlet pipe 20 is 100mm, and the inner diameter of the first inlet pipe 10 is 200mm.

[0039] Optionally, the flow control valve 50 in this embodiment is a ball valve, specifically, the flow control valve 50 in this embodiment is a V-type ball valve. A V-type ball valve is a specially designed regulating ball valve, its core feature being a V-shaped notch on the ball. By rotating the ball, the area of ​​the V-shaped opening is changed, achieving linear or equal percentage flow regulation. With an opening degree ranging from 0° to 90°, the flow rate change is linearly related to the opening degree, thus achieving precise flow regulation.

[0040] Furthermore, the V-shaped edge of the V-type ball valve cuts through fibers and particles such as pulp, mud, and sewage during opening and closing, helping to prevent the valve from jamming and preventing media from accumulating as it flows through the V-shaped opening. Additionally, V-type ball valves are typically made of materials such as PTFE and metal hard seals, ensuring a tight fit between the V-shaped edge and the valve seat when closed, resulting in high sealing performance and wear resistance.

[0041] In other possible implementations, the flow control valve 50 may also be an eccentric butterfly valve, a diaphragm valve, or a plug valve, etc. The specific structure of the flow control valve 50 is not uniquely limited in the embodiments of this application.

[0042] Optionally, the gate valve 40 in this embodiment is a non-rising stem gate valve. A non-rising stem gate valve is a type of gate valve in which the valve stem does not move with the rise and fall of the gate; the valve stem only rotates without axial displacement. Its structural design completely embeds the valve stem thread inside the valve body, preventing the thread from being exposed and avoiding jamming and corrosion. Furthermore, the valve plate is raised and lowered by rotating a handwheel, the exposed length of the valve stem is fixed, and a packing seal is used between the valve stem and the valve cover, resulting in good sealing performance.

[0043] In some embodiments, the water storage container 30 has an inlet communicating with the receiving cavity 200. The water supply valve 60 may include a valve disposed at the inlet and a floating element movably connected to the valve. The floating element can rise and fall with the liquid level in the receiving cavity 200. When the floating element is higher than a preset height, the floating element drives the valve to close or the inlet. When the floating element is lower than the preset height, the floating element drives the valve to open the inlet. By setting the floating element, when the liquid level in the receiving cavity 200 rises, the floating element can rise. When the liquid level reaches the preset height, the valve will close, at which point the injection of water into the receiving cavity 200 will stop. The structure is simple and can react quickly.

[0044] In some embodiments, such as Figure 1 and Figure 3 As shown, the water supply device also includes a water outlet pipe 71 connected to the receiving cavity 200 and a water pump 72 installed on the water outlet pipe 71. The water pump 72 is used to drive the liquid in the receiving cavity 200 to be discharged to the outside of the water storage container 30 through the water outlet pipe 71. By installing the water pump 72, when the water storage container 30 is over-supplied with water, the water pump 72 drives the liquid in the receiving cavity 200 to be discharged to the outside of the water storage container 30 through the water outlet pipe 71, thereby reducing safety hazards and further improving safety.

[0045] Optionally, multiple outlet pipes 71 can be installed to improve drainage efficiency. Additionally, as... Figure 1 and Figure 3 As shown, the outlet pipe 71 is equipped with a shut-off valve 73 and a check valve 74. The shut-off valve 73 allows the outlet pipe 71 to switch between on and off states, while the check valve 74 prevents fluid from flowing back into the water storage container 30. Additionally, the control box of the water pump 72 can be installed above the floor of the water supply equipment room. Increasing the installation height of the control box prevents damage to the control box in case of overflow, thus ensuring the normal operation of drainage.

[0046] In some embodiments, such as Figure 1 and Figure 3 As shown, the water storage container 30 includes a top wall 31 located above the liquid level in the receiving cavity 200 and an overflow port 32 located on the top wall 31 and communicating with the receiving cavity 200. The overflow port 32 is used to allow liquid in the receiving cavity 200 to overflow. By providing the overflow port 32, when the water level in the receiving cavity 200 is high, it can overflow through the overflow port 32, thereby further improving safety.

[0047] Optionally, the water storage container 30 also includes a cover 80 located at the overflow outlet 32, which partially covers the overflow outlet 32. Since the water storage tank can adopt a fully underground structure, that is, the entire water storage tank is below the ground level, and there may be personnel activity above the ground level, the cover 80 can prevent personnel from stepping into the overflow outlet 32, reducing safety hazards. In addition, the cover 80 partially covers the overflow outlet 32, that is, a gap is left between the cover 80 and the overflow outlet 32 ​​to allow water to overflow normally.

[0048] This utility model also proposes a water storage system, which includes a water supply device. The specific structure of the water supply device is as described in the above embodiments. Since this water storage system adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0049] In summary, when the water supply device of this application is in use, during normal use, the gate valve 40 is switched to the second state. At this time, the gate valve 40 disconnects the first water inlet pipe 10, so that the external water source can only supply water to the water storage container 30 through the second water inlet pipe 20. Furthermore, the flow control valve 50 can control the fluid flow of the second water inlet pipe 20, thereby achieving precise control of the water supply to the water storage container 30, preventing safety hazards caused by excessive water replenishment, and effectively improving safety. When it is necessary to quickly replenish the water in the water storage container 30, the gate valve 40 can be switched to the first state. At this time, the gate valve 40 opens the first water inlet pipe 10, so that the first water inlet pipe 10 supplies water to the water storage container 30. Thus, different water supply modes can be switched according to different water supply conditions, improving the applicability of the water supply device.

[0050] The above are merely optional embodiments of this application and are not intended to limit 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 the claims of this application.
