Description

Technical Field

[0001] This application relates to the field of valve technology, and in particular to a float valve and a liquid storage device. Background Technology

[0002] A float valve is an automatic valve that uses a float mechanism to control the flow of fluid. A typical float valve includes a float, valve body, valve core, and valve stem. The valve body is mounted on the side of the container. One end of the valve stem is connected to the float, and the other end is connected to the valve core. The valve stem is inclined relative to the container wall. The valve core is located within the valve body, which has an inlet and an outlet. The inlet pipe connects to the inlet, and the outlet faces the inside of the container. When the float valve is in use, liquid enters the valve body through the inlet and flows into the container through the outlet. As the liquid level rises, the float rises, causing the valve stem to rotate, which in turn moves the valve core. When the liquid level reaches a predetermined height, the valve core closes the inlet, preventing further liquid from entering the container. When the liquid level drops, the valve core opens the outlet, allowing liquid to flow back into the container through the outlet. This allows for control of the liquid level within the container.

[0003] However, the valve stem is inclined relative to the container wall and can rotate. The space required for the valve stem to rotate is relatively large, which makes the float valve occupy a large space and unsuitable for containers with small inner diameters. Utility Model Content

[0004] In view of this, this application provides a float valve and a liquid storage device to solve the problem that the valve stem is inclined relative to the container wall and can rotate, and the space required for the valve stem to rotate is large, which makes the float valve occupy a large space and unsuitable for containers with small inner diameters.

[0006] The valve core assembly extends in a predetermined direction, one end of the valve core assembly is connected to the float, and the other end of the valve core assembly extends into the flow space. The valve core assembly can move relative to the mounting assembly in the predetermined direction to close or open the liquid inlet.

[0007] Preferably, the mounting assembly includes a valve seat and a mounting component, the valve seat enclosing the flow space, and the valve seat having the liquid outlet at one end facing the float;

[0008] The mounting component is connected to the valve seat, and at least a portion of the mounting component is located within the flow space. The mounting component has a sliding channel that extends along the predetermined direction, and a portion of the valve core assembly is located within the sliding channel.

[0009] Preferably, the flow space is divided into a first cavity and a second cavity by the contact surface, the first cavity is located on the side of the second cavity opposite to the float in the predetermined direction, the diameter of the first cavity is larger than the diameter of the second cavity, and the contact surface is perpendicular to the predetermined direction;

[0011] Preferably, the valve core assembly includes a valve stem and a valve core, the valve stem being connected to the float ball, and a portion of the valve stem being located within the sliding channel, a portion of the valve core being located within the sliding channel, and the valve stem being capable of abutting against the valve core.

[0012] Preferably, the sliding channel is divided into a first sliding hole and a second sliding hole, the first sliding hole being located on the side of the second sliding hole facing away from the float in the predetermined direction, and the diameter of the first sliding hole being larger than the diameter of the second sliding hole;

[0013] The valve stem includes a first rod portion and a second rod portion, the diameter of the first rod portion is larger than the diameter of the second rod portion, the first rod portion is located in the first sliding hole, the second rod portion is located in the second sliding hole, and the diameter of the first rod portion is larger than the diameter of the second sliding hole.

[0015] Preferably, the float valve further includes an installation interface, which is connected to the valve seat. The installation interface has a through hole that extends through the installation interface along the predetermined direction and communicates with the liquid inlet.

[0016] Preferably, the float valve further includes a seal disposed between the mounting interface and the valve seat.

[0017] Preferably, the mounting interface has a first mounting groove on the side facing the valve seat, and the valve seat has a second mounting groove on the side facing the mounting interface.

[0018] The sealing element includes a main body, a first sealing part, and a second sealing part. The first sealing part and the second sealing part are respectively connected to the two sides of the main body in the predetermined direction. The first sealing part is located in the first mounting groove, and the second sealing part is located in the second mounting groove.

[0019] According to another aspect of this application, a liquid storage device is provided, the liquid storage device including a container and the above-described float valve, the mounting assembly being fixed to the container.

[0020] The float valve of this application includes a float, a valve core assembly, and a mounting assembly.

The valve core assembly extends along a predetermined direction, with one end connected to the float and the other end extending into the flow space. The valve core assembly can move relative to the mounting assembly along the predetermined direction to close or open the inlet. When the float valve is in use, the predetermined direction is parallel to the direction of gravity, allowing liquid to flow into the container through the inlet, the flow space, and the outlet. As the liquid level rises, the valve core assembly rises along the predetermined direction. When the valve core assembly closes the inlet, liquid no longer enters the container through the float valve. When the liquid level in the container drops, the valve core assembly descends along the predetermined direction, opening the inlet, allowing liquid to enter the container through the float valve. Because the valve core assembly moves along the predetermined direction with the rise or fall of the liquid level, the space required for its movement is small, and the entire float valve occupies a small space, making it suitable for containers with small inner diameters.

However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0031] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0032] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0033] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0034] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0035] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0036] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0037] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0039] According to one aspect of this application, a float valve is provided, such as... Figures 1 to 7 As shown, the float valve includes a float 1, a valve core assembly 2, and a mounting assembly 3. The mounting assembly 3 encloses a flow space 36 and has an inlet 34 and an outlet 35, both of which are connected to the flow space 36. The valve core assembly 2 extends along a predetermined direction L, with one end connected to the float 1 and the other end extending into the flow space 36. The valve core assembly 2 can move relative to the mounting assembly 3 along the predetermined direction L to close or open the inlet 34. When the float valve is in use, the predetermined direction L is parallel to the direction of gravity. Liquid can flow into the interior of the container through the inlet 34, the flow space 36, and the outlet 35. As the liquid level rises, the valve core assembly 2 rises along the predetermined direction L. When the valve core assembly 2 rises along the predetermined direction L to the point where it closes the inlet 34, the liquid no longer enters the container through the float valve. When the liquid level in the container drops, the valve core assembly 2 descends along the predetermined direction L, the inlet 34 opens, and the liquid can enter the container through the float valve. Because the valve core assembly 2 moves along the predetermined direction L with the rise or fall of the liquid level, the space required for the movement of the valve core assembly 2 is small, and the entire float valve occupies a small space, making it suitable for containers with small inner diameters.

[0040] In the embodiments of this application, such as Figures 2 to 6As shown, the mounting assembly 3 includes a valve seat 31 and a mounting member 32. The valve seat 31 can be a cylindrical hollow structure, so that the valve seat 31 encloses a flow space 36. A liquid outlet 35 is opened on the side of the valve seat 31 facing the float 1, which allows the liquid in the flow space 36 to flow into the container through the liquid outlet 35. The mounting member 32 is connected to the valve seat 31, and at least a portion of the mounting member 32 is located within the flow space 36. The mounting member 32 has a sliding channel 37 that extends along a predetermined direction L. A portion of the valve core assembly 2 is located within the sliding channel 37, which allows the sliding channel 37 to guide the movement of the valve core assembly 2 to ensure that the valve core assembly 2 moves along the predetermined direction L.

[0041] Furthermore, such as Figure 2 , Figure 5 and Figure 6 As shown, the sliding channel 37 is divided into a first sliding hole 371 and a second sliding hole 372. The first sliding hole 371 is located on the side of the second sliding hole 372 facing away from the float 1 in a predetermined direction L. The diameter of the first sliding hole 371 is larger than the diameter of the second sliding hole 372. The first sliding hole 371 and the second sliding hole 372 can be used to accommodate different parts of the valve core assembly 2, respectively.

[0042] Optionally, the mounting component 32 may be partially or entirely located within the flow space 36. Preferably, part of the mounting component 32 is located within the flow space 36, and another part is located outside the flow space 36. The number of liquid outlets 35 is multiple, and the multiple liquid outlets 35 are arranged around the mounting component 32.

[0043] Preferably, the entire mounting assembly 3 can be integrally molded.

[0044] like Figure 2 , Figure 3 and Figure 6 As shown, the flow space 36 is divided into a first cavity 361 and a second cavity 362 by the contact surface 39. The first cavity 361 is located on the side of the second cavity 362 facing away from the float 1 in a predetermined direction L. The diameter of the first cavity 361 is larger than the diameter of the second cavity 362. The contact surface 39 is perpendicular to the predetermined direction L. The mounting assembly 3 also includes a sealing seat 33, which has an inlet 34. At least a portion of the sealing seat 33 is located in the first cavity 361, and the sealing seat 33 abuts against the contact surface 39. In this way, the sealing seat 33 can be fixed by abutting against the contact surface 39, which facilitates the installation and removal of the sealing seat 33, thereby facilitating the installation of the valve stem 21 and the valve core 22 described below.

[0045] Optionally, such as Figure 3 and Figure 6As shown, the sealing seat 33 may include a first mounting portion 331 and a second mounting portion 332. The first mounting portion 331 and the second mounting portion 332 are connected to the side opposite to the float 1. In the direction from the valve seat 31 to the float 1, the outer diameter of the second mounting portion 332 gradually decreases. The first mounting portion 331 has a constant outer diameter structure, and its outer diameter is larger than the maximum outer diameter of the second mounting portion 332. The liquid inlet 34 penetrates the first mounting portion 331 and the second mounting portion 332 along a predetermined direction L. The first mounting portion 331 is located in the first cavity 361 and abuts against the contact surface 39, while the second mounting portion 332 is located in the second cavity 362.

[0046] In the embodiments of this application, such as Figure 2 As shown, the valve core assembly 2 includes a valve stem 21 and a valve core 22. The valve stem 21 is detachably connected to the float 1 to facilitate the replacement of different valve stems 21 and floats 1. When assembling the float valve, the sealing seat 33 can be separated from the valve seat 31, so that the valve stem 21 can be installed into the sliding channel 37 from the side where the first chamber 361 is located. Then, the valve core 22 is installed. After the valve core 22 is installed, the sealing seat 33 can be installed.

[0047] Optionally, the float 1 includes a ball body 11 and a connecting rod 12. The connecting rod 12 is connected to the ball body 11. The connecting rod 12 may have a threaded hole. The valve stem 21 can be detachably connected to the connecting rod 12 by means of a threaded connection. Alternatively, the connecting rod 12 has a fixing hole. Both the connecting rod 12 and the valve stem 21 have pin holes. A portion of the connecting rod 12 is inserted into the fixing hole, and a pin passes through the pin holes on the connecting rod 12 and the valve stem 21, thereby achieving a detachable connection between the float 1 and the valve stem 21.

[0048] Furthermore, part of the valve stem 21 is located within the sliding channel 37, and part of the valve core 22 is also located within the sliding channel 37, allowing the valve stem 21 to abut against the valve core 22. As the liquid level rises, the float 1 drives the valve stem 21 to rise. After the valve stem 21 moves to abut against the float 1, its continued rise pushes the valve core 22 upward. When the valve core 22 reaches the point where it blocks the inlet 34, the liquid can no longer enter the container through the inlet 34.

[0049] Preferably, the valve stem 21 includes a first stem portion 211 and a second stem portion 212. The diameter of the first stem portion 211 is larger than the diameter of the second stem portion 212. The first stem portion 211 is located within the first sliding hole 371, and the second stem portion 212 is located within the second sliding hole 372. The diameter of the first stem portion 211 is larger than the diameter of the second sliding hole 372. This prevents the first stem portion 211 from entering the second sliding hole 372, thus avoiding the valve stem 21 from sliding out of the sliding channel 37.

[0050] like Figure 3As shown, the valve core 22 includes a sliding portion 222 and a blocking portion 221. The sliding portion 222 may be cylindrical and is located within the first sliding hole 371, so that the first sliding hole 371 can guide the movement of the valve core 22. The blocking portion 221 may be hemispherical and is located outside the first sliding hole 371. The maximum diameter of the blocking portion 221 is larger than the diameter of the first sliding hole 371, which prevents the blocking portion 221 from entering the first sliding hole 371, thereby limiting the movement of the valve core 22.

[0051] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the float valve also includes a mounting interface 4, which is connected to the valve seat 31. The mounting interface 4 has a through hole 41 that extends through the mounting interface 4 in a predetermined direction L and communicates with the liquid inlet 34. The mounting interface 4 can be connected to the liquid inlet pipe to inject liquid into the container.

[0052] Furthermore, the float valve also includes a seal 5, which is disposed between the mounting port 4 and the valve seat 31 to achieve a seal between the mounting port 4 and the valve seat 31.

[0053] Optionally, such as Figure 3 , Figure 4 and Figure 7 As shown, the mounting interface 4 has a first mounting groove 42 on the side facing the valve seat 31, and the valve seat 31 has a second mounting groove 38 on the side facing the mounting interface 4. The sealing element 5 includes a main body 51, a first sealing part 52, and a second sealing part 53. The first sealing part 52 and the second sealing part 53 are respectively connected to the two sides of the main body 51 in a predetermined direction L. The first sealing part 52 is located in the first mounting groove 42, and the second sealing part 53 is located in the second mounting groove 38, thereby improving the stability of the sealing element 5 when installed between the valve seat 31 and the mounting interface 4.

[0054] Preferably, the seal 5 can be a gasket.

[0055] Furthermore, the mounting interface 4 is detachably connected to the valve seat 31. When the mounting interface 4 is separated from the valve seat 31 and the sealing seat 33 is separated from the valve seat 31, the valve stem 21 and the valve core 22 can be installed through the side where the first cavity 361 is located.

[0056] Optionally, the valve seat 31 and the mounting interface 4 can be connected by means of snap-fit, flange connection, threaded connection, grooved pipe fitting connection, etc. When the valve seat 31 and the mounting interface 4 are fixed by flange connection, flanges are formed on both the valve seat 31 and the mounting interface 4, and the flanges on the valve seat 31 and the mounting interface 4 are fixed by bolts.

[0057] When using the float valve of this application for liquid inlet, the mounting interface 4 is connected to the liquid inlet pipe. Liquid can enter the container through the liquid inlet 34, the flow space 36, and the liquid outlet 35. As the liquid level in the container rises, the float 1 floats up, thereby driving the valve stem 21 to move upward. After the valve stem 21 abuts against the valve core 22, the valve core 22 continues to rise, which will push the valve core 22 to move upward. When the valve core 22 closes the liquid inlet 34, the liquid no longer continues to flow into the container. When the liquid level in the container drops, the float 1 and the valve stem 21 drop, thereby realizing the drop of the valve core 22 and opening the liquid inlet 34, so that the liquid can enter the container through the liquid inlet 34, the flow space 36, and the liquid outlet 35.

[0058] According to another aspect of this application, a liquid storage device is provided, which includes a container and the aforementioned float valve, and has the same technical effects as the aforementioned float valve, which will not be described in detail here.

[0059] Optionally, the valve seat 31 can be connected to the container by welding, snap-fitting, or flange connection, thereby enabling the float valve to be fixed.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
