[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0033] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] Reference Figure 1 The first embodiment of this application provides a multifunctional valve fastening device, including a valve stem 1, a valve head 2, and a valve handle 3. The valve stem 1 includes a connecting end 11 and a fitting end, and a valve seat 12 is provided on the fitting end. The valve head 2 is fitted and connected to the valve seat 12, and a plurality of valve holes are provided on the valve head 2, each of which has a different cross-sectional area. The valve handle 3 is connected to the connecting end 11. Rotating the valve handle 3 drives the valve stem 1 to rotate, thereby realizing the rotation of the valve head 2.

[0036] The valve seat 12 on the mating end can be integrally formed with the valve stem 1. The valve seat 12 itself can be mated and connected with the underground valve, thereby rotating the underground valve and opening or closing it. When the size of the underground valve is too small to match the valve seat 12, the valve seat 12 can be mated with the valve head 2, so that the valve hole on the valve head 2 that can be mated with the underground valve is aligned with the underground valve, thus mating with it. By rotating the valve stem 1, the valve seat 12 and the valve head 2 are rotated, thereby rotating the underground valve and achieving the purpose of opening or closing it.

[0037] The valve head 2 is provided with several valve holes, which can specifically include 6 corresponding models of common underground valves, while the valve seat 12 itself can be matched with the largest common underground valve, so that the multi-functional valve fastening device can match common valve models; the valve hole models can be: 53×53mm, 37×37mm, 32×32mm, 28×28mm, 22×22mm, 12×12mm.

[0038] The valve handle 3 can be engaged with the connecting end 11 of the valve stem 1, thereby adjusting the length of the multi-functional valve fastening device as needed. This facilitates the engagement of the valve seat 12 or valve head 2 with the underground valve via the valve stem 1, thereby turning to open or close the underground valve for maintenance and pipeline operations.

[0039] The length of the valve handle 3 can be 60-70cm, specifically 66cm; the length of the valve stem 1 (including the valve seat 12) can be 150-160cm, specifically, the height of the valve seat 12 can be 7cm. It is suitable for underground pipeline operations that are buried deep, and facilitates the operation or maintenance of relief valve plugs or similar underground valves that are inconvenient to tighten with a wrench.

[0040] The multifunctional valve fastening device of this embodiment includes a valve stem 1, a valve head 2, and a valve handle 3. The valve stem 1 includes a connecting end 11 and a fitting end. The connecting end 11 is connected to the valve handle 3, and the length of the valve stem 1 can be extended and adjusted by the valve handle 3. The fitting end is provided with a valve seat 12, which can be fitted with an underground valve to open or close the underground valve. Alternatively, the valve seat 12 can be connected and fitted with the valve head 2, and then fitted with an underground valve through several valve holes provided on the valve head 2, thereby opening or closing the underground valve. The cross-sectional areas of the several valve holes on the valve head 2 are all different, and can be set to commonly used underground valve models as needed, so that the multifunctional valve fastening device can match different valve models.

[0041] Reference Figure 2 and Figure 3 In some embodiments, a magnetic layer 121 is provided on the valve seat 12, which is used to connect the valve seat 12 and the valve head 2. The valve seat 12 and the valve head 2 are preferably made of alloy or metal, which can be attracted by the magnetic layer 121, thereby stably connecting the valve seat 12 and the valve head 2. This also facilitates the disassembly and reassembly of the valve seat 12 and the valve head 2, making it suitable for matching different types of underground valves. The magnetic layer 121 can be a magnet.

[0042] The magnetic layer 121 can be disposed on the inner side of the valve seat 12, and can be used to directly contact the valve head 2, thereby magnetically connecting the valve seat 12 and the valve head 2; the magnetic layer 121 can also be disposed on the outer side of the valve seat 12, so that the valve seat 12 is magnetized by the magnetic layer 121, thereby tightly connecting with the valve head 2.

[0043] The magnetic layer 121 enables the multi-functional valve fastening device to quickly switch between valve head models 2 on-site, improving user efficiency and shortening installation time during emergency repairs of underground valves.

[0044] In some embodiments, a buffer layer 122 is provided on the magnetic layer 121, or a buffer layer 122 is provided on the side of the valve seat 12 opposite to the magnetic layer 121.

[0045] When the magnetic layer 121 can be disposed on the inner side of the valve seat 12, a buffer layer 122 can be disposed on the magnetic layer 121 to buffer the collision force when the valve seat 12 and the valve head 2 are magnetically connected, and to prevent damage to the magnetic layer 121. The buffer layer 122 can be directly bonded to the magnetic layer 121 and directly contact the valve head 2.

[0046] When the magnetic layer 121 is disposed on the outside of the valve seat 12, a buffer layer 122 is disposed on the side of the valve seat 12 away from the magnetic layer 121. That is, the buffer layer 122 is disposed on the valve seat 12. It is also used to buffer the collision force when the valve seat 12 and the valve head 2 are magnetically connected, so as to prevent the valve seat 12 from being damaged. The buffer layer 122 can be directly bonded to the inside of the valve seat 12.

[0047] Furthermore, the buffer layer 122 can also prevent the magnetic force of the magnetic layer 121 from being damaged due to collisions with the valve seat 12 when switching valve heads 2. Specifically, the buffer layer 122 should have pores and can be a foam layer, a plastic layer, or a rubber layer, and its thickness should not be too thick to prevent it from blocking the magnetism of the magnetic layer 121; that is, while ensuring that the valve seat 12 can quickly attract the valve head 2 through magnetism, the thickness of the buffer layer 122 is adjusted and set.

[0048] Reference Figure 4 and Figure 5 In some embodiments, the valve handle 3 is provided with a thread 31, and the inner side of the connecting end 11 is provided with a texture corresponding to the thread 31, or the outer side of the connecting end 11 is provided with a texture corresponding to the thread 31.

[0049] The valve handle 3 can be spirally engaged with the grooves on the connecting end 11 by the thread 31, thereby adjusting the length of the multi-functional valve fastening device for user convenience.

[0050] Specifically, the thread 31 on the valve handle 3 can be located on the inner or outer side of the valve stem 1. When the thread 31 is located on the outer side of the valve handle 3, the inner side of the connecting end 11 is provided with a pattern corresponding to the thread 31, which facilitates the valve handle 3 and the connecting end 11 to be engaged and screwed together to adjust the overall length. Similarly, when the thread 31 is located on the inner side of the valve handle 3, the outer side of the connecting end 11 is provided with a pattern corresponding to the thread 31, which also facilitates the valve handle 3 and the connecting end 11 to be engaged and screwed together to adjust the overall length.

[0051] In some embodiments, the valve seat 12 is provided with a plurality of fixing holes 123, and the magnetic layer 121 is provided with fixing protrusions 1211 corresponding to the fixing holes 123.

[0052] The magnetic layer 121 can be fitted with the fixing hole 123 of the valve seat 12 through the fixing protrusion 1211, thereby stably connecting the valve seat 12 and the magnetic layer 121. This facilitates quick replacement of the magnetic layer 121 when its magnetism is insufficient or damaged, ensuring the safety and reliability of the device. The number of fixing holes 123 can be set according to actual needs, preferably two or more.

[0053] In some embodiments, the valve stem 1 is provided with a connection hole 13, and the valve handle 3 passes through the connection hole 13 and is connected to the valve stem 1.

[0054] The valve stem 1 can be perpendicular to the valve stem 1 after passing through the connecting hole 13. The valve handle 3 can be used to adjust and extend the length of the valve stem 1, and can also be used to connect to the valve stem 1 through the connecting hole 13, serving as a handle for the user to rotate the valve stem 1.

[0055] Reference Figure 6 and Figure 7 In some embodiments, a limit rod 33 is provided on the valve handle 3, and the limit rod 33 is arranged perpendicularly to the valve handle 3.

[0056] When the valve handle 3 is fitted into the connecting end 11, thereby extending the length of the valve stem 1, the limiting rod 33 can keep the valve handle 3 completely embedded in the connecting end 11, making it inconvenient to pull it out; when the valve handle 3 is connected to the valve stem 1 through the through connecting hole 13, the limiting rod 33 can limit the connection position between the valve handle 3 and the connecting hole 13, thereby making it convenient for the user to apply force based on the fixed point position, thereby rotating the valve stem 1.

[0057] In some embodiments, the valve stem 1 is provided with an anti-slip surface 32. The anti-slip surface 32 is used to increase the coefficient of friction of the valve stem 1, making it easier for the user to contact and use the valve, and making it easier for the user to apply force.

[0058] In some embodiments, the valve head 2 has a cubic structure, and the valve head 2 includes a first side, a second side, a third side, a fourth side, a fifth side, and a sixth side, and valve holes are provided on the first side, the second side, the third side, the fourth side, the fifth side, and the sixth side.

[0059] The valve head 2 is a hollow cubic structure, preferably a cube, containing six sides, each with a valve hole. When different models of underground valves need to be matched, the side with the corresponding valve hole is aligned with the underground valve. The shape of the valve hole is not limited; specifically, it corresponds to the shape of the vent valve or other underground valve used in the application, and can be square, rectangular, or circular, etc., preferably square.

[0060] In some embodiments, the valve orifice includes a first valve orifice 21, a second valve orifice 22, a third valve orifice 23, a fourth valve orifice 24, a fifth valve orifice 25, and a sixth valve orifice. The first valve orifice 21 is disposed on the first side, the second valve orifice 22 is disposed on the second side, the third valve orifice 23 is disposed on the third side, the fourth valve orifice 24 is disposed on the fourth side, the fifth valve orifice 25 is disposed on the fifth side, and the sixth valve orifice (not shown in the figure) is disposed on the sixth side.

[0061] The first valve hole 21, the second valve hole 22, the third valve hole 23, the fourth valve hole 24, the fifth valve hole 25, and the sixth valve hole are respectively located on the first side, the second side, the third side, the fourth side, the fifth side, and the sixth side, with sizes of 53×53mm, 37×37mm, 32×32mm, 28×28mm, 22×22mm, and 12×12mm; all of them are square in shape.

[0062] The valve seat 12 of the multifunctional valve fastening device in this embodiment can correspond to one type of underground valve, and the valve seat can correspond to six different types of valves, making the multifunctional valve fastening device suitable for matching seven different types of underground valves. This gives the device a multi-purpose function, breaking the traditional operation mode that requires carrying multiple valve stems 1 of different specifications for replacement. It greatly reduces the equipment carrying burden of emergency repair personnel and emergency repair vehicles, reduces the time and labor costs caused by replacing valve stems 1, and significantly improves the convenience and flexibility of the work.

[0063] In summary, this application provides a multifunctional valve fastening device, including a valve stem, a valve head, and a valve handle. The valve stem includes a connecting end and a fitting end. The connecting end is connected to the valve handle, allowing the length of the valve stem to be extended and adjusted via the valve handle. The fitting end is provided with a valve seat, which can be fitted with an underground valve to open or close the underground valve. Alternatively, the valve seat can be connected and fitted with the valve head, and then fitted with an underground valve via several valve holes on the valve head to open or close the underground valve. The cross-sectional areas of the several valve holes on the valve head are all different, and can be configured to be the commonly used underground valve models as needed, thus enabling the multifunctional valve fastening device to match different valve models.

[0064] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing examples, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions in the examples of this application.
