Description

Technical Field

[0001] This utility model relates to the field of water tank technology, and in particular to a water tank inlet control device. Background Technology

[0002] Currently, water tank equipment in building water supply systems typically uses float valves for water level control. The float valve is connected to a float via a lever mechanism, and the float rises and falls with the water level in the tank. As the tank is continuously filled with water, the float rises with the water level and, through the lever mechanism, actuates the float valve, reducing the water inflow rate and thus limiting further water level rise, thereby controlling the water level.

[0003] However, float valves are usually installed directly in the water tank, which makes it extremely easy for the float to move up and down when the water level fluctuates when the tank is filled. This causes the float valve to open and close frequently when the tank is filled, making it difficult to achieve stable water level control. This not only generates noise but also seriously shortens the service life of the float valve.

[0004] On the other hand, float valves are prone to wear and tear after frequent opening and closing over a long period of time, requiring subsequent maintenance. Since the float valve is located in the water tank, maintaining the float valve also requires shutting down the water tank and draining the water, which undoubtedly affects the normal operation of the water tank.

[0026] Currently, water tank equipment in building water supply systems typically uses float valves for water level control. The float valve is connected to a float via a lever mechanism, and the float rises and falls with the water level in the tank. As the tank is continuously filled with water, the float rises with the water level and, through the lever mechanism, actuates the float valve, reducing the water inflow rate and thus limiting further water level rise, thereby controlling the water level.

[0027] However, float valves are usually installed directly in the water tank, which makes it extremely easy for the float to move up and down when the water level fluctuates when the tank is filled. This causes the float valve to open and close frequently when the tank is filled, making it difficult to achieve stable water level control. This not only generates noise but also seriously shortens the service life of the float valve.

[0028] On the other hand, float valves are prone to wear and tear after frequent opening and closing over a long period of time, requiring subsequent maintenance. Since the float valve is located in the water tank, maintaining the float valve also requires shutting down the water tank and draining the water, which undoubtedly affects the normal operation of the water tank.

[0029] In response, this application proposes a water tank inlet control device. By setting up a secondary tank, water in the main tank can flow to the secondary tank through a connecting mechanism. The float valve mechanism in the secondary tank completes the water level detection, thereby avoiding interference from water surface fluctuations when the main tank is filled with water to the float valve mechanism. Moreover, by closing the gate valve, the secondary tank and the main tank can be isolated, so that the float valve mechanism in the secondary tank can be maintained separately when the main tank continues to store water.

[0030] Reference Figure 1The water tank inlet control device of this application includes a water tank body 100, a water tank inlet pipe 200, a secondary tank 300, a connecting mechanism 400, and a float valve mechanism 500. The water tank body 100 and the secondary tank 300 together constitute the main structure of this water tank inlet control device. The water tank inlet pipe 200 can inject water into the water tank body 100, and then the water can flow to the secondary tank 300 through the connecting mechanism 400. Based on the principle of communicating vessels, the water level in the secondary tank 300 is consistent with the water level in the water tank body 100. The float valve mechanism 500 is installed in the secondary tank 300, and it can detect the water level height in the secondary tank 300, thereby determining the water level height in the water tank body 100. This design ensures that water surface fluctuations during filling of the water tank body 100 do not disturb the water level monitoring of the float valve mechanism 500.

[0031] Specifically, a water inlet pipe 200 is installed inside the water tank body 100, and the water inlet pipe 200 fills the water tank body 100 with water. An auxiliary tank 300 is installed on one side of the water tank body 100 and is connected to the water tank body 100 via a connecting mechanism 400. The connecting mechanism 400 includes a connecting pipe 410 and a gate valve 420. The two ends of the connecting pipe 410 are connected to the water tank body 100 and the auxiliary tank 300, respectively. The gate valve 420 is installed in the connecting pipe 410 to control the opening and closing of the connecting pipe 410.

[0032] The float valve mechanism 500 includes a float valve body 510 and a float 520. The float 520 is connected to the float valve body 510 by a lever. The float valve body 510 is installed in the auxiliary box 300 and is connected to the water tank inlet pipe 200 to control the water inlet rate of the water tank inlet pipe 200.

[0033] The water contained in the main water tank 100 can enter the auxiliary tank 300 through the connecting pipe 410 and lift the float 520.

[0034] When the water tank inlet control device is working normally, the gate valve 420 is open, and the water level in the water tank body 100 gradually rises as water is continuously added through the water tank inlet pipe 200. At the same time, some water also flows to the auxiliary tank 300 through the connecting pipe 410. As the water level gradually rises, the water surface touches the float ball 520, which floats on the water surface due to buoyancy until the float ball 520 rises and triggers the float valve body 510. The water inlet rate of the water tank inlet pipe 200 can be controlled by the float valve body 510.

[0035] When maintenance is required on the float valve mechanism 500 in the auxiliary tank 300, the gate valve 420 is closed, at which point the auxiliary tank 300 is not connected to the main water tank 100. After the water in the auxiliary tank 300 is emptied, the worker can then perform maintenance on the float valve mechanism 500. Thanks to the disconnection between the auxiliary tank 300 and the main water tank 100, the maintenance process will not affect the water storage operation of the main water tank 100.

[0036] Furthermore, the water tank inlet pipe 200 is installed on the side of the water tank body 100 away from the auxiliary tank 300, so that when the water tank inlet pipe 200 injects water into the water tank body 100, the source of water disturbance can be kept away from the auxiliary tank 300 as much as possible, and the disturbance of the water surface can be avoided from affecting the float valve mechanism 500 in the auxiliary tank 300.

[0037] Furthermore, a limiting component 310 is installed in the auxiliary box 300. The limiting component 310 can support the float 520, so that when the water level is low and has not yet touched the float 520, the float 520 can be supported and the weight of the float 520 and the lever will not be applied to the float valve body 510, thus reducing the wear and tear on the float valve body 510.

[0038] Regarding the specific structure of the limiting member 310, in some embodiments, the limiting member 310 is a convex structure disposed in the auxiliary box 300, and the float 520 can be supported by the limiting member 310. In this embodiment, the limiting member 310 is a mesh structure, and the limiting member 310 is horizontally placed in the auxiliary box 300. On the one hand, the mesh structure of the limiting member 310 does not limit the installation position of the float 520, and the float 520 can be supported accurately. On the other hand, referring to... Figure 2 The limiting component 310 has multiple mesh holes 311 to allow water to pass through. The limiting component 310 does not affect the rise and fall of the water level, and the multiple mesh holes 311 can also reduce the fluctuation of the water surface in the auxiliary box 300, thereby further improving the detection accuracy of the float valve mechanism 500.

[0039] Furthermore, the connecting mechanism 400 also includes a drain valve 430, which is installed in the connecting pipe 410. Opening the drain valve 430 allows water to be drained from the auxiliary tank 300. Therefore, when maintaining the float valve mechanism 500 in the auxiliary tank 300, the gate valve 420 in the connecting pipe 410 is first closed to disconnect the connection between the auxiliary tank 300 and the main tank 100. Then, the drain valve 430 is opened to drain the water from the auxiliary tank 300 until it is empty. Finally, the worker can inspect and repair the emptied auxiliary tank 300 and maintain the float valve mechanism 500. The design of the drain valve 430 allows for quick drainage of water from the auxiliary tank 300, thereby improving the efficiency of maintaining the float valve mechanism 500.

[0040] Furthermore, the drain valve 430 is located at the bottom of the auxiliary tank 300, so that when the drain valve 430 is opened, the water in the auxiliary tank 300 can be discharged from the drain valve 430 as quickly as possible.

[0041] Furthermore, the connecting mechanism 400 also includes a filter 440, which is installed in the connecting pipe 410 and is equipped with a filter screen or filter element to isolate impurities in the water tank body 100, thereby preventing impurities from entering the auxiliary tank 300 through the connecting pipe 410. This, in turn, prevents impurities from entering the float valve mechanism 500 and causing it to malfunction, thus extending the service life of the float valve mechanism 500.

[0042] Furthermore, a level control valve 210 is installed in the water tank inlet pipe 200. A float valve body 510 is connected to the level control valve 210, and the float valve body 510 can regulate the opening and closing of the level control valve 210. When the float 520 is pushed upwards by the water level, it can trigger the float valve body 510 via a lever. With the triggering of the float valve body 510, it can further adjust the level control valve 210, thereby reducing the water inlet efficiency of the water tank inlet pipe 200.

[0043] Regarding the connection between the float valve body 510 and the level control valve 210, in some embodiments, both the float valve body 510 and the level control valve 210 are electric valves, electrically connected to each other via wires. This allows the float valve body 510 to adjust the level control valve 210 through circuit control. In other embodiments, the float valve body 510 and the level control valve 210 interact via hydraulic or pneumatic means. When the float valve body 510 is triggered, it can act on the level control valve 210 via hydraulic or pneumatic pressure, thus making the level control valve 210 subject to the action of the float valve body 510.

[0044] Furthermore, the water tank inlet pipe 200 is connected to the water supply equipment. The water tank inlet pipe 200 is equipped with a main valve 220 to control its opening and closing. By controlling the opening and closing of the main valve 220, the rate and flow rate of water injected from the water tank inlet pipe 200 into the water tank body 100 can be adjusted.

[0045] Furthermore, the auxiliary housing 300 includes an auxiliary housing body 320 and a housing cover 330. The housing cover 330 is movably connected to the auxiliary housing body 320, and the housing cover 330 can seal the internal space of the auxiliary housing body 320. Thus, when no maintenance is required, the housing cover 330 covers the internal space of the auxiliary housing body 320, preventing external dust or impurities from entering the auxiliary housing 300 and causing contamination, keeping the internal environment of the housing cover 330 clean. When maintenance is performed on the float valve mechanism 500, the housing cover 330 can be opened to expose the internal environment of the auxiliary housing 300.

[0046] Regarding the movable connection between the lid 330 and the auxiliary box body 320, in some embodiments, the lid 330 and the auxiliary box body 320 are hinged, and the lid 330 is opened and closed by a flip-opening method; in other embodiments, the lid 330 can be slidably opened and closed with the auxiliary box body 320. Alternatively, it is easily understood that the lid 330 can also adopt other types of movable connection methods to achieve a similar opening and closing effect.

[0047] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
