Description

Technical Field

[0001] The utility model relates to the technical field of valve welding tooling, in particular to a single valve assembly device with adjustable groove gap. Background Art

[0002] Valves are important industrial control devices, widely used in industries such as petroleum, petrochemicals, electric power, and nuclear power. They block or connect the flow of media, change the direction of the flow, regulate the flow rate and pressure of media in pipelines, and ensure normal system operating parameters. Aligning valves with pipelines is a key step in ensuring the proper operation of fluid systems. Valves and pipelines can be connected using various methods, including flanged, threaded, and welded connections.

[0003] Single valves used in nuclear power plants are typically connected to pipelines via welding. Therefore, valve replacement in nuclear power plants requires a controllable gap between the valve and the pipeline, while also ensuring proper coaxiality between the pipeline and the valve. To address this technical requirement, technicians typically design specialized assembly devices to assist with assembly. However, existing assembly devices cannot achieve both gap adjustment and proper coaxiality, adversely affecting subsequent welding. Utility Model Content

[0004] In response to the technical problem that existing valve assembly devices are unable to adjust the gap and coaxiality, the utility model provides a single valve assembly device with adjustable groove gap, which can adjust the welding groove gap while ensuring the coaxiality of the valve connection end and the pipeline, thereby ensuring the quality of the welding between the valve and the pipeline.

[0005] The utility model is achieved through the following technical solutions:

[0006] The utility model provides a single-valve assembly device with adjustable groove clearance, comprising: a tooling base; a movable guide rail, the movable guide rail is arranged parallel to the length direction of the tooling base, and the end of the movable guide rail is connected to the tooling base; a first fixing component, the first fixing component is used to be fixedly connected to the pipe to be welded, the first fixing component is slidably connected to the movable guide rail, and the first fixing component can slide along the length direction of the movable guide rail; a second fixing component, the second fixing component is used to be fixedly connected to the connecting end of the valve to be welded, and the second fixing component is connected to the movable guide rail; a linear adjustment mechanism, the linear adjustment mechanism is arranged on the tooling base, and the linear adjustment mechanism is transmission-connected to the first fixing component so as to be able to drive the first fixing component to move.

[0007] It should be noted that most single valves used in nuclear power plants are connected to pipelines by welding. When replacing single valves in nuclear power plants, the gap between the valve and the pipeline must be controllable, and the coaxiality of the pipeline and the valve must be ensured. However, the existing assembly device cannot take into account both gap adjustment and coaxiality, which has an adverse effect on subsequent welding.

[0008] In view of this, the utility model provides a single valve assembly device with adjustable groove gap, including a tooling base, a movable guide rail, a first fixed component, a second fixed component and a linear adjustment mechanism. The movable guide rail is arranged parallel to the length direction of the tooling base, and the end of the movable guide rail is connected to the tooling base. The first fixed component is slidably connected to the movable guide rail, and the first fixed component can slide along the length direction of the movable guide rail. The second fixed component is connected to the movable guide rail. The linear adjustment mechanism is arranged on the tooling base and is transmission-connected to the first fixed component.

[0009] During use, the tooling base is set and fixed directly below the valve, and the first fixing component is fixedly connected to the corresponding end of the pipe to be welded, and the second fixing component is fixedly connected to the connecting end of the valve to be welded. Since the linear adjustment mechanism is set on the tooling base and is transmission-connected to the first fixing component, the first fixing component is driven to move relative to the tooling base by the linear adjustment mechanism, thereby driving the pipe to be welded away from or close to the connecting end of the valve to be welded, thereby adjusting the gap of the groove according to the welding process.

[0010] Among them, since the movable guide rail is arranged parallel to the length direction of the tooling base, and the end of the movable guide rail is connected to the tooling base, the first fixed component is slidably connected to the movable guide rail and can slide along the length direction of the movable guide rail, and the second fixed component is connected to the movable guide rail, which can fix the circumferential relative positions of the first fixed component and the second fixed component, and thus fix the circumferential relative positions of the connecting ends of the pipe to be welded and the valve to be welded, so that the pipe to be welded and the valve to be welded are coaxially arranged, and move along the length direction of the movable track during the movement of the first fixed component. Therefore, in the process of adjusting the gap of the groove, the circumferential relative positions of the pipe to be welded and the valve to be welded remain unchanged, that is, the coaxiality of the pipe to be welded and the valve to be welded remains unchanged.

[0011] Therefore, the single valve assembly device with adjustable groove gap provided by the utility model can ensure the coaxiality of the valve connection end and the pipeline while adjusting the welding groove gap, thereby ensuring the quality of the welding between the valve and the pipeline.

[0012] In an optional embodiment of the present application, two supports are provided on the tooling base, and the two supports are spaced apart along the length direction of the tooling base. The two ends of the movable guide rail are respectively connected to the corresponding supports to fix the movable guide rail and ensure that the relative position of the movable guide rail and the tooling base remains unchanged.

[0013] In an optional embodiment of the present application, an accommodating recess is provided at the upper end of each of the two supports, and the accommodating recess is used to accommodate the pipe to be welded to avoid interference between the support and the fixation of the pipe to be welded.

[0014] In an optional embodiment of the present application, the accommodating recess is an arc-shaped recess to prevent the accommodating recess from damaging the surface of the pipe to be welded.

[0015] In an optional embodiment of the present application, the movable guide rail is rod-shaped to facilitate sliding connection between the first fixed component and the movable guide rail.

[0016] In an optional embodiment of the present application, two movable guide rails are provided, and the two movable guide rails are arranged on both sides of the length direction of the tooling base to avoid circumferential offset when the first fixed component moves, further ensuring that the coaxiality of the pipe to be welded and the valve to be welded remains unchanged.

[0017] In an optional embodiment of the present application, the first fixing component is an annular clamp component, so as to facilitate connecting the first fixing component to the pipe to be welded.

[0018] In an optional embodiment of the present application, the second fixing component is an annular clamp component, so as to facilitate connecting the second fixing component to the valve to be welded.

[0019] In an optional embodiment of the present application, the first fixing assembly, the second fixing assembly and the linear adjustment mechanism are each provided in two groups, so as to simultaneously pair the connecting ends of the valves to be welded with the corresponding pipes to be welded.

[0020] In an optional embodiment of the present application, the linear adjustment mechanism includes an adjusting screw, both ends of which are rotatably connected to the tooling base, and the middle part of the adjusting screw is threadedly connected to the first fixed component. On the one hand, it can ensure that the linear adjustment mechanism can output sufficient adjustment torque, and on the other hand, it is convenient to accurately control the gap of the welding groove.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] The utility model provides a single valve assembly device with adjustable groove gap, which includes a tooling base, a movable guide rail, a first fixed component, a second fixed component and a linear adjustment mechanism. The movable guide rail is arranged parallel to the length direction of the tooling base, and the end of the movable guide rail is connected to the tooling base. The first fixed component is slidably connected to the movable guide rail, and the first fixed component can slide along the length direction of the movable guide rail. The second fixed component is connected to the movable guide rail. The linear adjustment mechanism is arranged on the tooling base and is transmission-connected to the first fixed component. When in use, the tooling base is set and fixed directly below the valve, and the first fixed component is fixedly connected to the end corresponding to the pipe to be welded, and the second fixed component is fixedly connected to the connecting end of the valve to be welded, so that the first fixed component is driven to move relative to the tooling base by the linear adjustment mechanism to adjust the groove gap. During the movement of the first fixed component, it moves along the length direction of the movable rail, and the circumferential relative position of the pipe to be welded and the valve to be welded remains unchanged. Therefore, while adjusting the welding groove gap, the coaxiality of the valve connecting end and the pipe can be guaranteed to ensure the quality of the welding between the valve and the pipe.

[0038] In order to solve the above-mentioned problems, the inventors innovatively designed the following technical solutions, and the specific implementation solutions of this application will be described in detail with reference to the accompanying drawings.

[0039] Example

[0040] Combine Figure 1-Figure 4 , this embodiment provides a single-valve assembly device with adjustable groove gap, including: a tooling base 10; a movable guide rail 20, the movable guide rail 20 is arranged parallel to the length direction of the tooling base 10, and the end of the movable guide rail 20 is connected to the tooling base 10; a first fixing component 30, the first fixing component 30 is used to be fixedly connected to the pipe 60 to be welded, the first fixing component 30 is slidably connected to the movable guide rail 20, and the first fixing component 30 can slide along the length direction of the movable guide rail 20; a second fixing component 40, the second fixing component 40 is used to be fixedly connected to the connecting end of the valve 70 to be welded, and the second fixing component 40 is connected to the movable guide rail 20; a linear adjustment mechanism 50, the linear adjustment mechanism 50 is arranged on the tooling base 10, and the linear adjustment mechanism 50 is transmission-connected to the first fixing component 30 to be able to drive the first fixing component 30 to move.

[0041] Specifically, the tooling base 10 is provided with two supports 11, which are spaced apart along the length direction of the tooling base 10. The two ends of the movable guide rail 20 are respectively connected to the corresponding supports 11 to fix the movable guide rail 20 and ensure that the relative position of the movable guide rail 20 and the tooling base 10 remains unchanged. It can be seen that the gap between the two supports 11 can accommodate the valve 70 to be welded, the first fixing component 30 and the second fixing component 40 (such as Figure 1 、 Figure 2 and Figure 4 ).

[0042] Combine Figure 3 and Figure 4 The upper ends of the two supports 11 are each provided with an accommodating recess 11 a, and the accommodating recess 11 a is used to accommodate the pipe 60 to be welded, so as to avoid interference between the support and the fixation of the pipe 60 to be welded.

[0043] In this embodiment, the receiving recess 11a is an arc-shaped recess to prevent it from damaging the surface of the pipe to be welded 60. Of course, the receiving recess 11a can also be a V-shaped recess, a trapezoidal recess, a square recess, etc., as long as it can accommodate the pipe to be welded 60.

[0044] Combine Figure 1 、 Figure 2 and Figure 4 The movable guide rail 20 is rod-shaped so as to facilitate sliding connection between the first fixed component 30 and the movable guide rail 20. To this end, a through hole is provided on the first fixed component 30 for the movable guide rail 20 to pass through, and correspondingly, blind holes are provided on the two supports 11 for accommodating the ends of the movable guide rail 20.

[0045] To this end, two movable guide rails 20 are provided, and the two movable guide rails 20 are arranged on both sides of the length direction of the tooling base 10 to avoid circumferential offset when the first fixed component 30 moves, and further ensure that the coaxiality of the pipe 60 to be welded and the valve 70 to be welded remains unchanged.

[0046] It is understood that the first fixing assembly 30 is an annular clamp assembly to facilitate connection of the first fixing assembly 30 to the pipe to be welded 60. In this embodiment, the first fixing assembly 30 includes a first arcuate lower clamp 31 and a first arcuate upper clamp 32, which are symmetrically arranged in a vertical direction. The first arcuate lower clamp 31 and the first arcuate upper clamp 32 are connected on opposite sides by first fixing bolts 33 to facilitate fixation to the pipe to be welded 60. To further improve the stability of the first fixing assembly 30 during movement, the first arcuate lower clamp 31 can be slidably connected to the tooling base 10.

[0047] Similarly, the second fixing assembly 40 is an annular clamp assembly, which facilitates connecting the second fixing assembly 40 to the valve 70 to be welded. In this embodiment, the second fixing assembly 40 includes a second curved lower clamp 41 and a second curved upper clamp 42, which are symmetrically arranged in a vertical direction. The second curved lower clamp 41 and the second curved upper clamp 42 are connected on opposite sides by second fixing bolts 43 to facilitate fixing to the valve 70 to be welded. To further improve the stability of the first fixing assembly 30 during movement, the second curved lower clamp 41 can be connected to the tooling base 10.

[0048] Generally speaking, two groups of the first fixing assembly 30 , the second fixing assembly 40 and the linear adjustment mechanism 50 are provided, so as to simultaneously mate the connecting ends of the valve 70 to be welded with the corresponding pipe 60 to be welded.

[0049] Recombination Figure 1 and Figure 2 The linear adjustment mechanism 50 includes an adjusting screw 51, both ends of which are rotatably connected to the tooling base 10, and the middle part of the adjusting screw 51 is screwed to the first fixing component 30. On the one hand, it can ensure that the linear adjustment mechanism 50 can output sufficient adjustment torque, and on the other hand, it is convenient to accurately control the gap of the welding groove.

[0050] It can be understood that one end of the adjusting screw 51 is rotatably connected to the corresponding support 11 , while the other end can be rotatably connected to the structure corresponding to the tooling base 10 , and can also be rotatably connected to the second arc-shaped lower hoop 41 .

[0051] In summary, the single valve assembly device with adjustable groove clearance provided in this embodiment includes a tooling base 10, a movable guide rail 20, a first fixed component 30, a second fixed component 40 and a linear adjustment mechanism 50. The movable guide rail 20 is arranged parallel to the length direction of the tooling base 10, and the end of the movable guide rail 20 is connected to the tooling base 10. The first fixed component 30 is slidably connected to the movable guide rail 20, and the first fixed component 30 can slide along the length direction of the movable guide rail 20. The second fixed component 40 is connected to the movable guide rail 20. The linear adjustment mechanism 50 is arranged on the tooling base 10 and is transmission-connected to the first fixed component 30.

[0052] During use, the tooling base 10 is set and fixed directly below the valve, and the first fixing component 30 is fixedly connected to the corresponding end of the pipe to be welded 60, and the second fixing component 40 is fixedly connected to the connecting end of the valve to be welded 70. Since the linear adjustment mechanism 50 is set on the tooling base 10 and is transmission-connected to the first fixing component 30, the first fixing component 30 is driven by the linear adjustment mechanism 50 to move relative to the tooling base 10, thereby driving the pipe to be welded 60 away from or close to the connecting end of the valve to be welded 70, thereby adjusting the gap of the groove according to the welding process.

[0053] Among them, since the movable guide rail 20 is arranged parallel to the length direction of the tooling base 10, and the end of the movable guide rail 20 is connected to the tooling base 10, the first fixed component 30 is slidably connected to the movable guide rail 20 and can slide along the length direction of the movable guide rail 20, and the second fixed component 40 is connected to the movable guide rail 20, which can fix the circumferential relative position of the first fixed component 30 and the second fixed component 40, and thus can fix the circumferential relative position of the connecting ends of the pipe to be welded 60 and the valve to be welded 70, so that the pipe to be welded 60 and the valve to be welded 70 are coaxially arranged, and move along the length direction of the movable rail during the movement of the first fixed component 30. Therefore, in the process of adjusting the gap of the groove, the circumferential relative position of the pipe to be welded 60 and the valve to be welded 70 remains unchanged, that is, the coaxiality of the pipe to be welded 60 and the valve to be welded 70 remains unchanged.

[0054] In summary, the single valve assembly device with adjustable groove gap provided in this embodiment can ensure the coaxiality of the valve connection end and the pipeline while adjusting the welding groove gap, thereby ensuring the quality of the welding between the valve and the pipeline.

[0055] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
