Description

Technical Field

[0001] This utility model relates to the field of cooling water replenishment technology, and in particular to a water replenishment device and a coating cooling water system. Background Technology

[0002] In the coating cooling water system, the cooling tower uses an open water tank. The water in the tank is consumed to varying degrees every day, so the tank needs to be replenished with water every day.

[0003] The current method for replenishing water in a pool typically involves installing a float valve at the outlet end of the outlet pipe. This float valve consists of a valve body switch and a float. The valve body switch is installed at the outlet end of the outlet pipe, while the float floats on the water surface. When the water level in the pool is too low, the float descends with the water level, causing the valve body switch to open and replenish the pool with water. Because the outlet end of the outlet pipe is directly in contact with the float on the water surface, the large flow of water during replenishment can easily impact the surface of the float, causing damage and reducing its service life, thus affecting the replenishment efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a water replenishment device and system, which aims to solve the problem of low water replenishment efficiency of existing water replenishment devices.

[0005] To solve the above problems, this utility model proposes a water replenishment device, comprising:

[0006] A water supply pipeline, the water supply pipeline including a connected inlet pipe and a first outlet pipe;

[0007] A first control valve, located on the first outlet pipe, is used to control the water flow from the first outlet pipe; and

[0008] A water level detection device, one end of which is electrically connected to the first control valve, and the other end of which is installed in an external water tank to detect the water level height of the external water tank. The installation position of the water level detection device is far away from the first outlet pipe.

[0009] When the water level detection device detects that the water level in the external water tank is lower than a preset threshold, it controls the first control valve to open, and the water in the inlet pipe flows through the first outlet pipe into the external water tank.

[0010] In one embodiment, the water level detection device includes a water level probe and a control device. The water level probe is installed in an external water tank, and the two ends of the control device are respectively connected to the water level probe and the first control valve.

[0011] The water level probe is used to detect the water level in the external pool. When the water level is too low, the water level probe sends a corresponding signal to the control unit, which then controls the first control valve to open.

[0012] In one embodiment, the water level detection device further includes a driving component. One end of the control component is electrically connected to the water level probe, and the other end is electrically connected to one end of the driving component. The other end of the driving component is pneumatically connected to the first control valve, which is a pneumatic butterfly valve.

[0013] In one embodiment, the water replenishment device further includes a second control valve, which is driven and connected to the first control valve to control the opening and closing speed of the first control valve.

[0014] In one embodiment, the water replenishment device further includes a second water outlet pipe, which is arranged in parallel with the first water outlet pipe. The inner diameter of the second water outlet pipe is smaller than that of the first water outlet pipe. One end of the second water outlet pipe is connected to the water inlet pipe, and the other end of the second water outlet pipe is equipped with an automatic water level control valve. The installation height of the water level control valve is greater than a preset water level threshold. The automatic water level control valve is used to detect the water level of the external water tank in real time and control its own opening to allow the water in the water inlet pipe to flow through the second water outlet pipe and be injected into the external water tank.

[0015] In one embodiment, the inner diameter of the second outlet pipe is D, where D is 25±0.1mm.

[0016] In one embodiment, the water replenishment device further includes a manual control valve, which is installed at one end of the second water outlet pipe.

[0017] In one embodiment, the water replenishment device further includes a main control valve located on the water inlet pipe. When the main control valve is open, the water inlet pipe is in a water-carrying state; when the main control valve is closed, the water inlet pipe is in a closed state.

[0018] This utility model also proposes a coating cooling water system, including a water replenishment device and a water tank. The water replenishment device is as described above. The water replenishment device is located at the opening edge of the water tank and is used to replenish water into the water tank.

[0019] This invention proposes a water replenishment device, including a water supply pipeline, a first control valve, and a water level detection element. When this device replenishes water to an external water tank, the water level detection element first detects that the water level in the tank is too low, and then drives the first control valve to open. After the first control valve opens, it adjusts its opening degree to ensure that the water flow from the inlet pipe can be injected into the external water tank from the first outlet pipe at a stable flow rate. The water replenishment device proposed in this invention uses a separate design for the water level detection element and the first control valve, allowing the water level detection element to be installed far away from the first outlet pipe. This prevents the water level detection element from being impacted by the water flow, increases its service life, significantly reduces maintenance time, and thus improves water replenishment efficiency.

[0028] The current method for replenishing water in a pool typically involves installing a float valve at the outlet end of the outlet pipe. This float valve consists of a valve body switch and a float. The valve body switch is installed at the outlet end of the outlet pipe, while the float floats on the water surface. When the water level in the pool is too low, the float descends with the water level, causing the valve body switch to open and replenish the pool with water. Because the outlet end of the outlet pipe is directly in contact with the float on the water surface, the large flow of water during replenishment can easily impact the surface of the float, causing damage and reducing its service life, thus affecting the replenishment efficiency.

[0029] To address the aforementioned problems, this utility model proposes a water replenishment device, aiming to solve the issue of low water replenishment efficiency in existing water replenishment devices.

[0030] like Figure 1 In one embodiment, the water replenishment device 10 includes a water supply pipeline 11, a first control valve 12, and a water level detection element 13. The water supply pipeline 11 includes a connected inlet pipe 111 and a first outlet pipe 112. The first control valve 12 is located on the first outlet pipe 112 and is used to control the water flow in the first outlet pipe 112. One end of the water level detection element 13 is electrically connected to the first control valve 12, and the other end is used to be installed in the external water tank 20 to detect the water level in the external water tank 20. The installation position of the water level detection element 13 is far away from the first outlet pipe 112.

[0031] In this embodiment, the water supply pipeline 11 is made of DN80 galvanized pipe, which gives the water supply pipeline 11 good corrosion resistance, effectively preventing rust and scaling on the inner wall of the pipe, ensuring smooth water flow, and avoiding the impact of pipe blockage on water replenishment efficiency. The inlet pipe 111 serves as the water inlet, with one end connected to an external water source to introduce sufficient water flow; the first outlet pipe 112 serves as the water output channel, with the other end connected to the first outlet pipe 112, which serves as the water output channel, to transport the water flow to the external water tank 20. The first control valve 12 is located at the connection between the inlet pipe 111 and the first outlet pipe 112. It can be a solenoid valve or a pneumatic valve. The operator can adjust the water flow rate in the first outlet pipe 112 by controlling the valve opening to achieve precise water replenishment control. A water level detection device 13 is installed inside the external water tank 20 and is used to monitor the water level in real time. Its main detection structure can be an ultrasonic level gauge, a water level probe 131, etc. It transmits the water level signal to the first control valve 12 via electrical connection to control the water replenishment operation. During the actual operation of the coating cooling water system, the cooling water in the external water tank 20 will continuously decrease due to evaporation, equipment wear, etc., causing the water level to gradually drop. At this time, the water level detection device 13 installed in the water tank 20 will monitor the water level in real time and convert the detected water level information into an electrical signal. When the water level drops below a preset threshold, the water level detection device 13 will immediately transmit this signal to the first control valve 12. After receiving the signal, the first control valve 12 opens the valve according to the preset control logic, and water from the external water source flows into the water supply pipeline 11 through the inlet pipe 111, and then into the external water tank 20 through the first outlet pipe 112. As the water level in pool 20 rises, the water level detection device 13 continuously monitors the water level change. When the water level is detected to reach or exceed the preset threshold, the water level detection device 13 will send a signal to the first control valve 12 again to control the first control valve 12 to close and stop the water replenishment operation, thereby keeping the water level in pool 20 within a reasonable range and ensuring the stable operation of the coating cooling water system.

[0032] The water replenishment device 10 proposed in this utility model adopts a separate design of water level detection element 13 and first control valve 12, which keeps water level detection element 13 away from the water flow interference area, reduces the adverse effects of external factors, reduces the probability of component damage, extends the service life of water level detection element 13, reduces equipment replacement costs, avoids water replenishment delay or inaccuracy caused by failure of water level detection element 13, ensures that the water level of water tank 20 is always maintained within a reasonable range, ensures the stable operation of coating cooling water system, and thus improves the efficiency of the entire coating production process.

[0033] like Figure 1 In one embodiment, the water level detection device 13 includes a water level probe 131 and a control device 132. The water level probe 131 is installed in the external water tank 20, and the two ends of the control device 132 are respectively connected to the water level probe 131 and the first control valve 12.

[0034] The water level probe 131 is used to detect the water level of the external water tank 20. When the water level is too low, the water level probe 131 sends a corresponding signal to the control unit 132, and the control unit 132 controls the first control valve 12 to open.

[0035] In this embodiment, the water level probe 131 is a liquid level probe with high, medium, and low positions. The probe length is cut according to the water level height of the pool 20 so that it is submerged inside the pool 20. When the water level is below the medium level, the water level probe 131 forms a conductive circuit with the water flow and generates an electrical signal, which is transmitted to the controller. The controller then controls the first control valve 12 to open, thereby replenishing water to the pool 20. In this embodiment, the water level probe enables remote control of the first control valve 12, ensuring that the first control valve 12 can work normally while protecting itself from the impact of the water flow, thus improving its service life and improving the water replenishment efficiency.

[0036] like Figure 1 In one embodiment, the water level detection component 13 further includes a drive component 133, one end of the control component 132 is electrically connected to the water level probe 131, the other end is electrically connected to one end of the drive component 133, and the other end of the drive component 133 is pneumatically connected to the first control valve 12, which is a pneumatic butterfly valve.

[0037] In this embodiment, the control component 132 includes a water level relay and an intermediate relay. One end of the water level relay is electrically connected to the water level probe 131, and the other end is electrically connected to the intermediate relay. The drive component 133 is a pneumatic solenoid valve, one end of which is electrically connected to the intermediate relay, and the other end is connected to the first control valve 12 via an air pipe. The water level relay then transmits the signal from the water level probe 131 to the intermediate relay. Upon receiving the signal, the internal electromagnetic coil of the intermediate relay generates magnetic force, driving the valve core of the pneumatic solenoid valve to actuate, allowing compressed air to enter the pneumatic butterfly valve, which serves as the first control valve 12, through the air pipe, thus opening it.

[0038] This pneumatic butterfly valve mainly consists of a valve body, a butterfly plate, a valve stem, and a pneumatic actuator. The valve body is the main structure of the valve and is installed between the inlet pipe 111 and the first outlet pipe 112. The butterfly plate is installed inside the valve body and connected to the pneumatic actuator via the valve stem. Its rotation controls the flow of water. The valve stem transmits torque, transferring the power of the pneumatic actuator to the butterfly plate. The pneumatic actuator receives external control signals and uses compressed air to drive the valve stem to rotate, thereby rotating the butterfly plate and opening and closing the valve. The pneumatic butterfly valve has a relatively simple structure, fewer parts, lower manufacturing costs, and a longer service life. As the first control valve 12, it maintains good performance under frequent opening and closing and flow regulation over long periods, reducing equipment replacement costs, saving operating expenses for enterprises, and improving economic efficiency.

[0039] like Figure 1 In one embodiment, the water replenishment device 10 further includes a second control valve 14, which is driven and connected to the first control valve 12 to control the opening and closing speed of the first control valve 12.

[0040] In this embodiment, the second control valve 14 is a throttle valve, which is installed above the first control valve 12 to control the first control valve 12 to open or close slowly, so that the change in water flow speed is more stable, greatly reducing the impact of water flow on the water supply pipeline 11, thereby improving the service life of the water replenishment device 10.

[0041] In other embodiments, the first control valve 12 may also be a solenoid valve.

[0042] like Figure 1 In one embodiment, the water replenishment device 10 further includes a second water outlet pipe 113, which is arranged in parallel with the first water outlet pipe 112. The inner diameter of the second water outlet pipe 113 is smaller than that of the first water outlet pipe 112. One end of the second water outlet pipe 113 is connected to the inlet pipe 111, and the other end of the second water outlet pipe 113 is equipped with an automatic water level control valve 15. The installation height of the water level control valve is greater than the preset water level threshold. The automatic water level control valve 15 is used to detect the water level height of the external water tank 20 in real time and control its own opening to inject the water in the inlet pipe 111 into the external water tank 20 through the second water outlet pipe 113.

[0043] In this embodiment, the second outlet pipe 113 serves as an auxiliary water flow channel for the water replenishment device 10. It is connected to the first outlet pipe 112 via a T-joint and is also connected to the inlet pipe 111. It is also made of galvanized pipe. An automatic water level control valve 15 is installed at the outlet of the second outlet pipe 113. This valve can be a float valve, which mainly consists of a float, a linkage mechanism, a valve core, and a valve body. The float is typically a hollow sphere, usually made of plastic or stainless steel, and can float on the water surface. The linkage mechanism connects the float and the valve core. When the float rises or falls with the water level, it drives the valve core to move via the linkage. The valve core is installed inside the valve body and, through its cooperation with the valve seat, opens and closes the valve, controlling the flow of water. When the water level drops, the float descends, driving the valve core to move via the linkage mechanism, gradually opening the valve. Water from the inlet pipe 111 flows slowly into the external water tank 20 through the second outlet pipe 113, achieving a small amount of water replenishment. As the water level gradually rises, the float also rises, and the linkage mechanism drives the valve core to move in the opposite direction, gradually closing the valve. This combination of the second outlet pipe 113 and the automatic water level control valve 15 allows for small-scale water replenishment when water level changes are minor and the water level probe 131 cannot detect the change, further improving the practicality of the water replenishment device 10. Simultaneously, the second outlet pipe 113 uses a smaller inner diameter, resulting in a lower flow rate under the same water pressure, enabling precise control of the water replenishment amount. This addresses minor water level fluctuations in the coating cooling water system caused by slight equipment wear or natural evaporation, further improving the water replenishment accuracy of the water replenishment device 10.

[0044] Furthermore, in one embodiment, the inner diameter of the second water outlet pipe 113 is D, where D is 25±0.1mm.

[0045] In this embodiment, the inner diameter of the second outlet pipe 113 is designed to be 25±0.1mm, which can meet the micro-water replenishment needs of most coating cooling water systems when the water level fluctuates slightly, without causing impact on the second outlet pipe 113 during water replenishment due to excessive pipe diameter. At the same time, the 25mm pipe diameter is an industrial standard size, which is convenient for purchase and installation, further reducing the manufacturing and installation costs for enterprises.

[0046] like Figure 1 In one embodiment, the water replenishment device 10 further includes a manual control valve 16, which is installed at one end of the second water outlet pipe 113.

[0047] In this embodiment, the manual control valve 16 can be a manual gate valve, a manual shut-off valve, or a manual ball valve, etc. It is installed at the end of the second outlet pipe 113 near the water supply pipe. The design of the manual control valve 16 facilitates the maintenance and debugging of the second outlet pipe 113. During maintenance, the manual control valve 16 can be used to cut off the water flow, which facilitates the inspection and replacement of components such as the second outlet pipe 113 and the float valve, further improving the flexibility of the water supply device 10.

[0048] like Figure 1 In one embodiment, the water replenishment device 10 further includes a main control valve 17, which is located in the water inlet pipe 111. When the main control valve 17 is open, the water inlet pipe 111 is in a water-carrying state, and when the main control valve 17 is closed, the water inlet pipe 111 is in a closed state.

[0049] In this embodiment, the main control valve 17 can be a manual ball valve or a pneumatic shut-off valve. During the operation of the water replenishment device 10, the main control valve 17 acts as a main switch. When the main control valve 17 is in the open state, water from the external water source can smoothly enter the inlet pipe 111 and then be injected into the external water tank 20 through the first outlet pipe 112 and the second outlet pipe 113. When the main control valve 17 is closed, the water flow channel of the inlet pipe 111 is cut off, and neither the first outlet pipe 112 nor the second outlet pipe 113 can obtain water, thus achieving the effect of stopping water replenishment. During equipment maintenance, operators can close the main control valve 17 to cut off the water supply, ensuring that maintenance personnel can safely inspect, repair, and replace the first control valve 12, water level detection device 13, second outlet pipe 113, and related components in a waterless environment. When the coating cooling water system is shut down for a long time or does not require water replenishment, closing the main control valve 17 can avoid water waste caused by pipe leaks, valve failures, etc. In addition, in case of emergencies, such as the bursting of the inlet pipe 111 or external water source pollution, the main control valve 17 can be quickly closed to prevent the accident from escalating and ensure the safety of the entire water replenishment device 10 and the coating cooling water system.

[0050] like Figure 1 The present invention also proposes a coating cooling water system, which includes a water replenishment device 10 and a water tank 20. The specific structure of the water replenishment device 10 is as described in the above embodiments. Since the water replenishment device 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
