Description

Technical Field

[0001] This utility model relates to a safety valve adjustment device, and more particularly to a safety valve adjustment device. Background Technology

[0002] Valves are widely used in equipment maintenance, pipeline system installation, or precision instrument adjustment. Existing rotary valves have two valve bodies, upper and lower, which are fixed by threads. When disassembling and assembling, it is necessary to unscrew the two valve bodies or the valve body and the valve seat.

[0003] First, since the valve and valve seat are tightly fitted components, directly bearing the spring force, disassembly requires overcoming both thread friction and spring force simultaneously. Reassembly also necessitates maintaining coaxial alignment. Second, the complex working environment can lead to corrosion or adhesion over time. All of these factors contribute to difficulties in disassembly and assembly. Furthermore, the diverse shapes of valves on the market significantly increase the challenge, currently relying on lathes or single-tool disassembly. This method generally results in low coaxiality, requires multiple operators, is inefficient, and easily damages the threads. Moreover, different valves require different tools for disassembly and assembly, adding to the inconvenience of carrying them.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is: on the basis of solving the problem of disassembly and assembly of valve body and valve seat, to solve the problem of incompatibility between valve body and tools used for disassembly and assembly.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model claims a safety valve adjustment device, including an adjustment component and a conversion unit. The adjustment component is detachably mounted on the valve body via the conversion unit. The valve body is threadedly connected to the valve seat. The adjustment component is configured to drive the valve body to rotate relative to the valve seat around the valve body axis.

[0008] Preferably, the upper end of the conversion unit and the lower end of the adjustment component are connected by a plug-in joint, which restricts the degree of freedom of relative rotation between the adjustment component and the conversion unit;

[0009] The lower end of the switching unit and the upper end of the valve body form a plug-in fit, which restricts the degree of freedom of relative rotation between the valve body and the switching unit.

[0010] Preferably, the adjustment component includes a fixed unit and a handheld unit. The upper end of the conversion unit is plugged into the fixed unit. The fixed unit is in the shape of a stepped shaft, and the bottom diameter of the fixed unit is larger than the top diameter of the fixed unit. The top of the fixed unit is connected to the handheld unit, and the handheld unit and the fixed unit are perpendicular to each other.

[0011] Preferably, the fixing unit includes a base and a connecting shaft. The upper end of the conversion unit and the lower end of the base are connected by a plug-in joint. One end of the connecting shaft is installed on the upper end of the base to form a stepped shaft shape. The connecting shaft is arranged coaxially with the conversion unit. A handheld unit is installed on the other end of the connecting shaft. The handheld unit and the axis of the connecting shaft are perpendicular to each other.

[0012] Preferably, the conversion unit includes a central shaft section, the lower end of which is recessed in a first groove or protruded in a first protrusion, and the first groove or first protrusion and the upper end of the valve body form an insertion fit.

[0013] Preferably, the first groove is a polygonal groove, a straight groove, or a cross-shaped groove, and the first protrusion is a polygonal block, a straight block, or a cross-shaped block that cooperates with it.

[0014] Preferably, the upper end of the central shaft section is provided with a second groove or a second protrusion, and the second groove or the second protrusion and the lower end of the adjustment component are connected in an interlocking manner with another second protrusion or another second groove.

[0015] Preferably, the second groove is a spline groove, and the second protrusion is a spline block that mates with it.

[0016] Preferably, the central axis segment is a solid segment.

[0017] Preferably, the surface of the conversion unit that comes into contact with the regulating component and the valve body is provided with an anti-wear coating.

[0018] The advantages of this utility model are:

[0019] First, by setting up a conversion unit that matches the adjustment component, and considering that different valve bodies require different adjustment components, the conversion unit enables quick installation of the adjustment component and the valve body, thereby increasing the applicability of the adjustment component.

[0020] Second, the upper and lower ends of the conversion unit are respectively adjusted to fit into the valve body, ensuring the coaxiality of the conversion unit, the bottom end of the adjustment component, the valve body and the valve seat, which facilitates the installation and use of the adjustment component.

[0021] Third, the adjustment component is equipped with a handheld unit, which uses the lever principle to increase the adjustment torque. This allows the operator to obtain greater adjustment power with less force, and is also suitable for situations where the valve body and valve seat are installed very tightly or where adjustment is inconvenient due to rust.

[0022] Fourth, the fixed unit is set in a stepped shaft shape. Firstly, this is to ensure that the diameter of the base is as large as possible, which ensures the strength of the adjustment component and increases its service life when installed with the valve body. Secondly, it can provide a good diameter transition between the handheld unit and the adjustment component, avoiding the handheld unit being too large and inconvenient to carry or hold.

[0023] Fifth, the conversion unit includes a central shaft section to ensure the overall rigidity and strength of the conversion unit. In actual operation, the conversion unit may have grooves at both the top and bottom. The entire adjustment device needs to be unscrewed from the valve seat and valve body during use, and it bears a large force. Therefore, it is necessary to ensure that the conversion unit has at least one solid section to improve the overall strength of the conversion unit, avoid damage, and extend its service life.

[0024] 6. During the adjustment process, the areas with the greatest wear are the valve body, the adjustment group, and the switching unit. By setting an anti-wear coating, wear can be reduced and the service life of the device can be improved. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Example 1

[0037] See Figure 1 This embodiment claims protection for a safety valve adjustment device, including an adjustment component 1 and a conversion unit 2. The adjustment component 1 is detachably mounted on the valve body 3 via the conversion unit 2. The surface of the conversion unit 2, which contacts the adjustment component 1 and the valve body 3, is provided with an anti-wear coating. During the adjustment process, the position with the greatest wear is the position where the valve body 3, the adjustment component 1 and the conversion unit 2 are in contact. By providing an anti-wear coating, wear can be reduced and the service life of the device can be improved.

[0038] Furthermore, the upper end of the conversion unit 2 and the lower end of the adjustment component 1 are connected in a plug-in fit, which restricts the degree of freedom of relative rotation between the adjustment component 1 and the conversion unit 2; the lower end of the conversion unit 2 and the upper end of the valve body 3 are connected in a plug-in fit, which restricts the degree of freedom of relative rotation between the valve body 3 and the conversion unit 2.

[0039] The valve body 3 is threaded onto the valve seat 4, and the adjusting component 1 is configured to drive the valve body 3 to rotate relative to the valve seat 4 about the axis of the valve body 3.

[0040] See 1 to Figure 2 Furthermore, the conversion unit 2 includes a central shaft section 20, which is a solid section. The central shaft section 20 is included in the conversion unit 2 to ensure the overall rigidity and strength of the conversion unit 2. In actual operation, the conversion unit 2 may have grooves at both the top and bottom. The entire adjustment device needs to be unscrewed from the valve seat 4 and valve body 3 during use, and it bears a large force. Therefore, it is necessary to ensure that the conversion unit 2 has at least one solid section to improve the overall strength of the conversion unit 2, avoid damage, and increase its service life.

[0041] The upper end of the central shaft section 20 is provided with a second groove or a second protrusion. The second groove or the second protrusion and the lower end of the adjustment component 1 are connected in a plug-in fit. The second groove is a spline groove and the second protrusion is a spline block that mates with it.

[0042] Furthermore, the lower end of the central shaft section 20 is provided with a first groove or a first protrusion. The first groove or the first protrusion and the other first protrusion or the other first groove on the upper end of the valve body 3 form an insertion fit. The first groove is a polygonal groove and the first protrusion is a polygonal block that fits with it.

[0043] See Figure 3 Here, taking the first groove recessed at the lower end of the central shaft section 20 as an example, it forms an insertion fit with another first protrusion protruding at the upper end of the valve body 3.

[0044] It is worth mentioning that the upper and lower ends of the conversion unit 2 are respectively adjusted by the assembly 1 and the valve body 3, which ensures the coaxiality of the conversion unit 2, the bottom of the adjustment assembly 1, the valve body 3 and the valve seat 4, and facilitates the installation and use of the adjustment assembly 1.

[0045] See Figures 1 to 3 Furthermore, the adjustment component 1 includes a fixed unit 10 and a handheld unit 11. The upper end of the conversion unit 2 is plugged into the fixed unit 10. The fixed unit 10 is in the shape of a stepped shaft, and the bottom diameter of the fixed unit 10 is larger than the top diameter of the fixed unit 10. The fixed unit 10 includes a base 101 and a connecting shaft 102. The upper end of the conversion unit 2 is plugged into the bottom end of the base 101. One end of the connecting shaft 102 is installed on the upper end of the base 101, forming a stepped shaft shape. The fixed unit 10 is set as a stepped shaft shape. Firstly, it is to ensure that the diameter of the base 101 is as large as possible. In this way, the strength of the adjustment component 1 is guaranteed, and the service life is increased when it is installed with the valve body 3. Secondly, it can provide a good diameter transition between the handheld unit 11 and the adjustment component 1, so as to avoid the handheld unit 11 being too large and inconvenient to carry or hold.

[0046] The connecting shaft 102 is arranged coaxially with the conversion unit 2. The other end of the connecting shaft 102 is equipped with a handheld unit 11. The axis of the handheld unit 11 and the axis of the connecting shaft 102 are perpendicular to each other. The top of the fixing unit 10 is connected to the handheld unit 11. The handheld unit 11 and the fixing unit 10 are perpendicular to each other.

[0047] It should be noted that the adjustment component, by setting up a handheld unit, uses the lever principle to increase the adjustment torque, allowing the operator to obtain greater adjustment power with less force. It is also suitable for situations where the valve body and valve seat are installed very tightly or where adjustment is inconvenient due to rust.

[0048] This utility model claims protection by setting a conversion unit 3 that is matched with the adjustment component 1. Considering that different valve bodies 3 require different adjustment components 1, the conversion unit 3 enables quick installation of the adjustment component 1 and the valve body 3, thereby increasing the applicability of the adjustment component 1.

[0049] Example 2

[0050] See Figure 5 The difference between this embodiment and embodiment one is that the first groove is a straight groove and the first protrusion is a polygonal block or a straight block that cooperates with it.

[0051] Example 3

[0052] See Figure 6 The difference between this embodiment and Embodiment 1 is that the first groove is a cross-shaped groove and the first protrusion is a cross-shaped block that cooperates with it.

[0053] In practical application, the specific implementation steps of this utility model are as follows:

[0054] Step 1: Select conversion unit 3. Based on the valve port of valve body 4, select the appropriate conversion unit 3. Generally, valve body 4 valve port is of standard size. If non-standard parts are encountered, conversion unit 3 can be customized in advance to match it.

[0055] Step 2: Install the adjustment component 1, plug the conversion unit 3 into the valve body 1, and then plug the adjustment component 1 into the conversion unit 3.

[0056] Step 3: Adjust adjustment component 1 and rotate handheld unit 12 to unscrew valve body 4 from valve seat 5.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this 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 of the technical features.
