[0002] A valve is a device used to control the flow of fluids (liquids, gases, powders), usually used in piping systems. Valves can open, close, and adjust fluid flow to meet process requirements or safety needs. Common valve types include ball valves, gate valves, butterfly valves, check valves, etc. In the fields of engineering and manufacturing, valves are widely used in various process flows.

[0003] However, in the prior art, the existing valves need to be positioned during the processing. However, when positioning, the traditional method uses a bolt-type positioning method, which will cause part of the valve surface area to be blocked, affecting subsequent processing, hindering the smooth progress of the process, and affecting the processing quality and efficiency. In addition, when the bolts are processed to a certain extent, the processing operation may be restricted due to the influence of the bolts, which will result in more time and effort being spent in the processing process to overcome this obstacle.

[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0026] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0027] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] Example 1

[0029] like Figure 1-4 As shown, the utility model provides a technical solution: a positioning device for a valve, comprising: a positioning mechanism 1, a supporting mechanism 2 is arranged on the top of the positioning mechanism 1, the positioning mechanism 1 comprises a side plate 11, a hollow cylinder 12 is arranged inside one side of the side plate 11, a telescopic rod 13 is arranged inside the hollow cylinder 12, a connecting column 14 is arranged at one end of the telescopic rod 13, an inclined rod 15 is arranged on one side of the connecting column 14, an arc plate 16 is arranged at one end of the inclined rod 15, a hollow cylinder 12 is arranged on the outer side of the connecting column 14, a slide groove 17 is opened on the top of the arc plate 16, a slider 18 is arranged on the inner surface of the slide groove 17, a U-shaped plate 19 is arranged on the top of the slider 18, a vertical rod 110 is arranged on the inner side of the U-shaped plate 19, an insert rod 111 is arranged on the outer side of the vertical rod 110, a slider 18 is arranged on the bottom end of the vertical rod 110, and a slide rail 112 is arranged on the top of the side plate 11.

[0030] In this embodiment, when the valve needs to be positioned, the position of the valve opening is aligned with the hollow cylinder 12 so that the end of the hollow cylinder 12 can enter the opening. At this time, the telescopic rod 13 is retracted. During this process, the inclined rod 15 on the connecting column 14 gradually changes from an inclined form, so that the angle of inclination becomes smaller, and the arc plate 16 is affected by it, and the distance between it and the hollow cylinder 12 increases, so that the outer side of the arc plate 16 fits with the inner side of the valve opening. In this way, the valve is positioned by the internal expansion method, which can ensure that the valve is accurately positioned at the required position and the valve will not accidentally move or deviate from the required position. In addition, the internal expansion method has a faster speed for positioning the valve.

[0031] Secondly, there is a mounting hole at the opening of the valve. Therefore, the slider 18 needs to be adjusted as needed. If adjustment is required, slide the slider 18 in the slide groove 17 to make the U-shaped plate 19 and the mounting hole at the same horizontal line. At this time, the plug rod 111 and the mounting hole are not at the same height. The plug rod 111 can be adjusted in the U-shaped plate 19 until it is engaged with the mounting hole. This ensures that the valve is firmly fixed in the required position during installation, and this connection method helps prevent unnecessary rotation or shaking of the valve during positioning.

[0032] Example 2

[0033] like Figure 1-4 As shown, the support mechanism 2 includes a support seat 21, one end of the side of the support seat 21 is connected with one end of the limiting rod 22, the bottom end of the limiting rod 22 is vertically engaged with the concave hole on the slide rail 112, and the surface of the slide rail 112 is slidably connected with the bottom of the support seat 21.

[0034] In this embodiment, before positioning the valve, the valve is first placed on the support seat 21, and then pushed on the slide rail 112 to make it close to the hollow cylinder 12. When it is close to a certain degree, the support seat 21 is restricted by inserting the limit rod 22 into the recessed hole on the slide rail 112. This limitation can prevent the support seat 21 from becoming unstable due to external forces during the valve positioning process, thereby ensuring the stability and reliability of the valve positioning. Under the action of the support seat 21, part of the pressure is also shared by the hollow cylinder 12, thereby providing additional support and fixation.

[0035] Working principle:

[0036] like Figure 1-4 As shown, by retracting the telescopic rod 13, the inclined rod 15 on the connecting column 14 will gradually evolve from an inclined form during this process, so that the angle of inclination becomes smaller, and the arc plate 16 is affected by it, and the distance between it and the hollow cylinder 12 increases, so that the outer side of the arc plate 16 fits with the inner side of the valve opening, and the valve is positioned by the internal expansion method. Secondly, by sliding the slider 18 in the slide groove 17, the U-shaped plate 19 and the mounting hole are on the same horizontal line. At this time, the insertion rod 111 and the mounting hole are not at the same height. The insertion rod 111 can be adjusted in the U-shaped plate 19 until it is engaged with the mounting hole position. This can ensure that the valve is firmly fixed in the desired position during the installation process.

[0037] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0038] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
