Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valve processing, in particular to a pressure reducing valve fixing component. Background Art

[0002] Pressure reducing valves, a common valve element, are often used in pipelines. They control flow and pressure within pipelines, maintaining a predetermined flow rate, limiting excess flow to a predetermined value, and appropriately reducing upstream high pressure. Even if pressure changes upstream of the main valve, the flow rate downstream of the main valve remains unchanged. Therefore, precise machining is crucial to ensure accurate flow control.

[0003] Prior art typically uses a vise to clamp and secure the pressure-reducing valve. Because the valve is subject to forces from the machining components during machining, the vise must provide a high clamping pressure to ensure stability during processing. However, this high clamping pressure can damage the valve surface, rendering it unqualified. Furthermore, the vise must be adjusted each time the valve is removed or placed, making the entire process cumbersome. Utility Model Content

[0033] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The following combination Figure 1The present invention describes a pressure reducing valve fixing assembly comprising a fixing block 1, a connecting block 2, and multiple limiting posts 4. The connecting block 2 is connected to the fixing block 1 and is used to receive the pressure reducing valve 3. Multiple limiting posts 4 are located on the side of the connecting block 2 facing away from the fixing block 1. Each limiting post 4 abuts the pressure reducing valve 3, and at least one limiting post 4 is provided on each side of the pressure reducing valve 3.

[0035] Please refer to Figures 1 to 4 The pressure reducing valve fixing assembly includes a fixing block 1. In this embodiment, the shape of the fixing block 1 is selected to be a rectangular parallelepiped, so that the fixing block 1 can have multiple flat surfaces. The upper surface of the fixing block 1 is used to install the connecting block 2 to ensure the stability of the installation of the connecting block 2. Because the fixing block 1 needs to be clamped by the vise 7, the front and rear surfaces of the fixing block 1 are also planes, so that when the fixing block 1 is clamped by the vise 7, the surface of the fixing block 1 and the clamping surface of the vise 7 can be better fitted together, thereby improving the stability of the clamping of the vise 7. In different embodiments, the shape of the fixing block 1 can be changed according to the shape of the clamping surface in the vise 7 to ensure that the vise 7 and the fixing block 1 remain in contact when the vise 7 clamps the fixing block 1.

[0036] After the connecting block 2 is installed on the fixed block 1 through the lower surface, a plurality of limiting columns 4 are installed on the upper surface of the connecting block 2. The upper surface of the connecting block 2 is used to place the pressure reducing valve 3, and then the pressure reducing valve 3 is limited by the limiting columns 4. Specifically, in this embodiment, the pressure reducing valve 3 has four side surfaces, and the four side surfaces are connected end to end, and the angle between two adjacent side surfaces is 90°. Then, in this embodiment, taking four limiting columns 4 as an example, the four limiting columns 4 are respectively arranged corresponding to the four side surfaces of the pressure reducing valve 3. That is, after the pressure reducing valve 3 is placed on the upper surface of the connecting block 2, at least one limiting column 4 is provided at the position of each side surface of the pressure reducing valve 3.

[0037] Preferably, in this embodiment, to maintain the stability of the pressure reducing valve 3, the limiting posts 4 are arranged according to the size and shape of the pressure reducing valve 3. Not only is there at least one limiting post 4 at each side of the pressure reducing valve 3, but each limiting post 4 is also aligned with the corresponding side. In the mating relationship between the pressure reducing valve 3 and the limiting posts 4, this embodiment preferably employs an interference fit, so that the pressure reducing valve 3 and the limiting posts 4 abut against each other. The limiting posts 4 not only limit the pressure reducing valve 3, but also clamp the pressure reducing valve 3 through the mating relationship, thereby increasing the stability of the pressure reducing valve 3.

[0038] In this embodiment, the pressure-reducing valve 3 is first supported by the connecting block 2. Then, a limiting post 4 is arranged on the connecting block 2 to limit the position of the pressure-reducing valve 3. After the pressure-reducing valve 3 is positioned on the connecting block 2, the connecting block 2 is connected to the vise 7 via the fixing block 1 on its lower surface. The vise 7 indirectly positions the pressure-reducing valve 3 by clamping the fixing block 1. During the positioning process, the vise 7 avoids direct contact with the pressure-reducing valve 3, thereby preventing wear on the outer surface of the valve 3 and improving the yield rate of the finished product.

[0039] In one embodiment, a limiting hole 5 is provided on one side of the connecting block 2 connected to the limiting column 4 , and the limiting hole 5 is engaged with the pressure reducing valve 3 .

[0040] like Figure 2 As shown, a limit hole 5 is provided on the upper surface of the connecting block 2. Correspondingly, a raised portion is also provided on the pressure reducing valve 3. In this embodiment, the raised portion on the pressure reducing valve 3 is located at the center of the lower surface of the pressure reducing valve 3. Therefore, the limit hole 5 should be provided at the center of the upper surface of the connecting block 2 so that when the pressure reducing valve 3 is installed on the connecting block 2, the raised portion on the pressure reducing valve 3 can align with the limit hole 5 and be inserted, thereby engaging with the limit hole 5.

[0041] Furthermore, the protrusion on the pressure reducing valve 3 is circular, so the limiting hole 5 is also circular, and their sizes correspond to each other. This allows the protrusion on the pressure reducing valve 3 to fit snugly with the limiting hole 5 after it is inserted into the limiting hole 5. Furthermore, because the protrusion on the pressure reducing valve 3 is circular and the limiting hole 5 is also circular, after the pressure reducing valve 3 and the limiting hole 5 are engaged, the limiting hole 5 can only limit the movement of the pressure reducing valve 3 in a direction perpendicular to the axis of the limiting hole 5. However, the limiting hole 5 cannot limit the rotation of the pressure reducing valve 3 about the axis of the limiting hole 5. Therefore, in this embodiment, the pressure reducing valve 3 is also limited by a limiting post 4.

[0042] In this embodiment, the limiting hole 5 not only serves to limit the pressure reducing valve 3, but also serves to position the pressure reducing valve 3, because only after the protrusion of the pressure reducing valve 3 is aligned with the limiting hole 5 can the pressure reducing valve 3 be successfully placed on the connecting block 2. In addition, the limiting hole 5 can also screen the pressure reducing valve 3 in advance, because the relative position of the limiting hole 5 and the limiting post 4 will not easily change after production without external force. If the pressure reducing valve 3 is placed on the connecting block 2, and the side of the pressure reducing valve 3 is in contact with the limiting post 4, and the protrusion of the pressure reducing valve 3 cannot be aligned and inserted, it means that the size of the pressure reducing valve 3 is incorrect, it is a defective product, and needs to be replaced.

[0043] Because the relative positional relationship between the side of the pressure reducing valve 3 and the limiting post 4 remains consistent after the side of the pressure reducing valve 3 and the limiting post 4 are in contact, and the relative positional relationship between the limiting hole 5 and the limiting post 4 remains unchanged, the relative positional relationship between the side of the pressure reducing valve 3 and the limiting hole 5 remains unchanged. If the protrusion of the pressure reducing valve 3 cannot be aligned with the limiting hole 5, it means that the relative positional relationship between the protrusion of the pressure reducing valve 3 and the side of the pressure reducing valve 3 has changed, which means that the size of the pressure reducing valve 3 is incorrect. This allows the pressure reducing valve 3 to be screened in advance, avoiding the situation where the pressure reducing valve 3 is found to be incorrectly sized after processing, thus saving resources.

[0044] In one embodiment, each limiting column 4 is further provided with a limiting protrusion 8 on the side facing the pressure reducing valve 3 , and the pressure reducing valve 3 is provided with a limiting groove, and the limiting protrusion 8 is engaged with the limiting groove of the pressure reducing valve 3 .

[0045] Please refer to Figure 2 and Figure 3 In this embodiment, four limiting columns 4 are taken as an example, and four limiting protrusions 8 are also provided, so each limiting column 4 is connected to a corresponding limiting protrusion 8. Because there are four limiting grooves on the pressure reducing valve 3, four limiting protrusions 8 are taken as an example in this embodiment. In different embodiments, the number of limiting protrusions 8 needs to be changed according to the number of limiting grooves on the actual pressure reducing valve 3. For example, when there are five limiting grooves on the pressure reducing valve 3, there also needs to be five limiting protrusions 8. The limiting protrusion 8 is connected to the limiting column 4 and is supported by the limiting column 4, so there also needs to be five limiting columns 4. The rest of the cases can be deduced by analogy and will not be elaborated here.

[0046] When the pressure reducing valve 3 is placed on the connecting block 2, the side of the pressure reducing valve 3 first fits against the limiting column 4. At the same time, the limiting groove on the pressure reducing valve 3 is aligned with the limiting protrusion 8. During the placement of the pressure reducing valve 3, the limiting groove and the limiting protrusion 8 are engaged and connected. Until the pressure reducing valve 3 is completely placed on the connecting block 2, the limiting protrusion 8 is also completely embedded in the limiting groove, thereby further limiting the pressure reducing valve 3.

[0047] In one embodiment, the pressure reducing valve fixing assembly further includes a limiting slot 6 , which is provided on a side of the connecting block 2 receiving the pressure reducing valve 3 , and the limiting column 4 is engaged with the limiting slot 6 .

[0048] like Figure 2As shown, a limiting slot 6 is provided on the upper surface of the connecting block 2 for mounting a limiting post 4. To ensure accurate positioning of the limiting post 4 when installed on the connecting block 2, the limiting slot 6 serves to limit the position of the limiting post 4. During installation, once the limiting post 4 is inserted into the limiting slot 6, the inner wall of the limiting slot 6 restricts the movement of the limiting post 4 on the upper surface of the connecting block 2, making installation of the limiting post 4 simpler, more convenient, and more accurate.

[0049] In one embodiment, the connection block 2 is provided with a plurality of mounting holes, the number of the mounting holes is greater than the number of the limiting columns 4, and the plurality of limiting columns 4 are installed in a plurality of different mounting holes to form different limiting spaces.

[0050] In this embodiment, in order to enable the limiting column 4 to be installed at different positions on the connecting block 2, a plurality of mounting holes are provided on the connecting block 2 (not shown in the figure). Figure 2 Take four mounting holes as an example). Because the limiting column 4 needs to abut against the side of the pressure reducing valve 3, the pressure reducing valve 3 can be limited. Different pressure reducing valves 3 have different sizes. When pressure reducing valves 3 of different sizes are placed on the connecting block 2, there may be a gap between the pressure reducing valve 3 and the limiting column 4, or the size of the pressure reducing valve 3 may be too large to fit between multiple limiting columns 4. Therefore, the connecting block 2 in this embodiment provides multiple mounting holes. When it is necessary to install pressure reducing valves 3 of different sizes, it is only necessary to adjust the installation position of the limiting column 4 according to the actual size of the pressure reducing valve 3. Then the limiting column 4 can be made to fit and abut against the pressure reducing valve 3 again to keep the position of the pressure reducing valve 3 accurate.

[0051] In one embodiment, a plurality of sliding grooves are provided on the connecting block 2 , and a plurality of limiting posts 4 are respectively connected to the plurality of sliding grooves, so that the plurality of limiting posts 4 are all slidably connected to the connecting block 2 .

[0052] Furthermore, the design of a sliding connection between the limiting post 4 and the connecting block 2 also allows the placement of the limiting post 4 to be changed. Once the size of the pressure reducing valve 3 is determined, the limiting post 4 slides on the connecting block 2 to the corresponding position and then locks to keep the limiting post 4 fixed. When replacing the pressure reducing valve 3 with a different size, the limiting post 4 is unlocked, allowed to slide to the corresponding position, and then locked again, thus accommodating pressure reducing valves 3 of different sizes.

[0053] The sliding method provided in this embodiment can make the adjustment of the limiting column 4 simpler and more convenient.

[0054] In one embodiment, the pressure reducing valve fixing assembly includes four limiting posts 4 , which are respectively arranged at four corners of the connecting block 2 .

[0055] like Figure 1As shown, this embodiment has four limiting posts 4. Because the limiting grooves of the pressure reducing valve 3 are formed at the four corners of the pressure reducing valve 3, the limiting posts 4 also need to be arranged according to the position of the limiting grooves. After the four limiting posts 4 are respectively arranged at the four corners of the connecting block 2, it is easier to engage the limiting posts 4 with the limiting grooves during installation of the pressure reducing valve 3.

[0056] In one embodiment, the structural strength of the fixing block 1 is greater than the structural strength of the limiting pillars 4. In one embodiment, the plurality of limiting pillars 4 are detachably connected to the connecting block 2. In one embodiment, the fixing block 1 and the connecting block 2 are welded.

[0057] In this application, the fixing block 1 is connected to the vise 7, which clamps the fixing block 1, thus exerting considerable pressure on the fixing block 1. Therefore, to increase the service life of the fixing block 1, the fixing block 1 is designed to have a relatively high structural strength. However, the limiting post 4 abuts the pressure reducing valve 3, and to prevent damage to the pressure reducing valve 3, the limiting post 4 has a relatively low structural strength.

[0058] Because the structural strength of the fixing block 1 is greater than that of the limiting posts 4, the service life of the fixing block 1 is greater than that of the limiting posts 4. Therefore, the likelihood of the fixing block 1 needing to be replaced is low, so the fixing block 1 and the connecting block 2 are welded to maintain relative fixation between the fixing block 1 and the connecting block 2. However, the service life of the limiting posts 4 is shorter, so to facilitate the maintenance and replacement of the limiting posts 4, the limiting posts 4 and the connecting block 2 are detachably connected. If one of the limiting posts 4 is damaged, it can be replaced individually, without having to replace the entire post, thus saving resources.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
