Description

Technical Field

[0001] This utility model belongs to the field of valve technology and relates to a valve handle. Background Technology

[0002] Ball valves are commonly used valves. They are operated by rotating a valve stem around a handle, which in turn rotates the ball inside the valve, thus opening and closing the valve. Ball valve handles come in various shapes and sizes, including elongated handles, butterfly handles, handwheels, and more.

[0003] For example, a ball valve handle was designed and a Chinese patent was applied for, with application number 201330195541.0 and publication number 302642057S. The ball valve handle is long and narrow, with a connection hole at one end for connecting with a valve, and a leather sleeve on the outer side of the other end.

[0004] The leather sleeve on the aforementioned ball valve handle can be designed in colors such as red, blue, yellow, and green, making it highly visible. However, during production, to prevent the sleeve from falling off, it is often fitted tightly to the outside of the handle, resulting in high friction and making the sleeve difficult to install and remove. Once manufactured, it is difficult to replace or adjust it according to the actual usage environment. Therefore, in actual use, the ball valve handle lacks the function of indicating the corresponding pipeline. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a valve handle that solves the problem of the lack of indication function in existing handles.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A valve handle includes a long strip-shaped handle body, one end of which has a connecting portion for connecting to a valve. The handle body has a through hole extending through its other side. The valve handle also includes a long strip-shaped indicator element, with a first and a second fastening portion at each end. The indicator element is bent, and the first and second fastening portions extend from the two ends of the through hole and are fastened to each other.

[0008] In this valve handle, a through hole is formed at the other end of the handle body, and an indicator is fastened to this through hole for indication. The indicator is connected via a snap-fit ​​method for easy installation. The appropriate color of the indicator can be selected based on the actual operating environment of the valve and the media in the pipeline network, thus enabling the valve handle to provide indication and facilitating user operation.

[0009] In the aforementioned valve handle, the second snap-fit ​​part is annular, with an annular groove recessed into its inner wall. The outer side of the first snap-fit ​​part has an annular protrusion. The first snap-fit ​​part extends into the second snap-fit ​​part, and the protrusion engages with the corresponding groove. The connection and fixation of the first snap-fit ​​part and the second snap-fit ​​part are achieved through the engagement of the annular protrusion and the annular groove, resulting in good connection stability and preventing detachment.

[0010] In the aforementioned valve handle, the inner wall of the second fastening part has two annular protruding rings, a first protrusion and a second protrusion. The groove is located between the first and second protruding rings. When the protrusion passes through the inner hole of the first protrusion and engages with the groove, the end of the first fastening part abuts against the second protrusion. By using the first and second protruding rings to hold the protrusion in place, and by using the second protrusion to limit the end of the first fastening part, the connection positioning becomes more accurate, ensuring the stability of the connection.

[0011] In the valve handle described above, the first fastening part is annular. Both the first and second fastening parts are annular, creating a hollow space inside the connection position to facilitate tool insertion for disassembly.

[0012] In the valve handle described above, the through hole is a square hole, and both the first and second fastening parts are square annular. The fit between the square hole and the square annular shape prevents the indicator from rotating relative to the handle, keeping its position fixed and facilitating observation.

[0013] In the valve handle described above, the outer side of the first fastening part has an outwardly protruding annular edge, and the outer side of the second fastening part has an outwardly protruding annular edge. Edge one and edge two can respectively abut against the two sides of the handle body. By abutting edge one and edge two against the opposite sides of the handle body, the overall integrity between the indicator and the handle body is improved, resulting in a more stable structure and more intuitive indication.

[0014] Compared to existing technologies, this valve handle features a through hole at the other end of the handle body, where an indicator is attached for indication. The indicator is connected via a snap-fit ​​mechanism, facilitating installation. Appropriate colors of indicator elements can be selected based on the valve's operating environment and the media in the pipeline network, ensuring the valve handle provides clear indication and ease of use for the user.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 and Figure 2 As shown, this valve handle includes a long, narrow handle body 1 and a long, narrow indicator 2. One end of the handle body 1 has a connecting portion 11 for connecting to the valve, which can be a round hole or a square hole. A through hole 12 is provided through the side of the other end of the handle body 1. The two ends of the indicator 2 have a first fastening portion 21 and a second fastening portion 22, respectively. The indicator 2 is bent, and the first fastening portion 21 and the second fastening portion 22 extend from the two ends of the through hole 12 and fasten together. In this embodiment, the indicator 2 can be made of rubber or plastic material to allow it to be bent and to allow the fastening position to deform and return to its original position during fastening. Its color can be red, blue, etc.

[0020] Specifically, the through hole 12 is a square hole, and the first fastening part 21 and the second fastening part 22 are square annular. The inner wall of the second fastening part 22 has two protruding annular protrusions, a first protrusion 25 and a second protrusion 26, which are spaced apart and form an annular groove 23 between them. The first protrusion 25 is closer to the first fastening part 21 than the second protrusion 26, and the inner hole width of the second protrusion 26 is smaller than that of the first protrusion 25, that is, the second protrusion 26 is more protruding than the first protrusion 25. The outer side of the first fastening part 21 has a protruding annular protrusion 24. When the first fastening part 21 extends into the second fastening part 22 and the protrusion 24 passes through the inner hole of the first protrusion 25 and is engaged in the groove 23, the end of the first fastening part 21 can abut against the second protrusion 26 to achieve a limiting position. In this embodiment, the outer side of the first fastening part 21 has an outwardly protruding annular piece-shaped edge 27, and the outer side of the second fastening part 22 has an outwardly protruding annular piece-shaped edge 28. Both the first edge 27 and the second edge 28 are located outside the through hole 12, and the first edge 27 and the second edge 28 can respectively abut against the two opposite sides of the handle 1.

[0021] In this valve handle, a through hole 12 is formed at the other end of the handle body 1, and an indicator 2 is fastened to this through hole 12. Different colors of indicator 2 are used to indicate different usage environments, thus serving an indication function. Here, the indicator 2 is connected by a fastening method, which is convenient for installation. The appropriate color of indicator 2 can be selected and replaced according to the actual usage environment of the valve and the different media in the pipeline network.
