Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0028] The inventor of the embodiment of the utility model found during the research process that since the stop valve is in the cut-off state, resetting its reset rod needs to overcome the force of the natural gas in the pipeline, so the force required for resetting is very large.

[0029] refer to Figure 1 and Figure 2 Some embodiments of the present invention provide a stop valve assembly, including a stop valve and a reset operation device. Figure 2 As shown, the stop valve is arranged on the natural gas pipeline to control the on-off of the natural gas pipeline. The stop valve includes a valve body 210 and a reset rod 220 movably arranged relative to the valve body 210. The reset rod 220 is configured to move relative to the valve body 210 in a direction away from the valve body 210 to reset the stop valve. Figure 1 As shown, the reset operation device includes a clamping member 30 and an operating rod 10. The clamping member 30 is used to clamp with the reset rod 220. One end of the operating rod 10 is connected to the clamping member 30, and the other end of the operating rod 10 is configured to receive an external force so that the clamping member 30 drives the reset rod 220 to move in a direction away from the valve body 210 under the action of the external force.

[0030] The stop valve assembly of some embodiments of the utility model is specially provided with a reset operating device for resetting the reset rod 220 of the stop valve, and the reset operating device is provided with a clamping member 30 clamped with the reset rod 220 and an operating rod 10 for the operator to apply external force, so that when the reset rod 220 of the stop valve needs to be reset, a force can be directly applied to the end of the operating rod 10 away from the clamping member 30, and then the reset rod 220 is lifted. The stop valve assembly of the embodiment of the utility model resets the reset rod 220 by providing a reset operating device. When resetting is required, the operating rod 10 can be directly pressed downward, and the operation difficulty is reduced compared with the need to manually lift the reset rod. The reduction in the difficulty of operation is also conducive to improving the reset efficiency.

[0031] In some embodiments, the reset rod 220 includes a convex ring. The clamping member 30 is clamped with the convex ring of the reset rod 220. When in use, the clamping port of the clamping member 30 is inserted into the gap between the convex ring of the reset rod and the valve body below, and a downward force is applied to the operating rod 10 to lift the reset rod of the stop valve to the flow position, and then the reset rod can be taken out after the reset is completed.

[0032] It should also be noted here that the stop valve mentioned in the embodiment of the present invention is a stop valve commonly used in the art for on-off control of pipelines, and the present invention does not limit the shape, structure, etc. of the stop valve.

[0033] That is to say, the reset operation device of the embodiment of the utility model is detachably arranged relative to the stop valve and can be taken out after the reset is completed.

[0034] refer to Figure 1 and Figure 3 In some embodiments, the reset operating device further includes a support rod 20. The first end of the operating rod 10 is connected to the clamping member 30. The second end of the operating rod 10 forms an external force application end. The support rod 20 is connected to the operating rod 10 and forms a fulcrum for the operation of the operating rod 10. The reset operating device of the utility model embodiment is provided with the support rod 20, so that the operating rod 10 takes the support rod 20 as a fulcrum, thereby forming a lever structure, and the second end of the operating rod 10 forms an external force application end. The use of the lever structure for reset can save effort and further reduce the difficulty of reset.

[0035] In some embodiments, reference Figure 1 and Figure 3 , the first end of the support rod 20 is connected to the operating rod 10. In order to achieve the resetting of multiple stop valves, the resetting operation device also includes a roller device 40 arranged at the second end of the support rod 20. After resetting one of the stop valves, the operator can push the resetting operation device to make the roller device 40 roll along the wall or the ground to move to the position of another stop valve to continue the resetting operation.

[0036] like Figure 4 As shown, in some embodiments, the roller device 40 includes a support 41 connected to the second end of the support rod 20 and at least one roller 42 rotatably disposed on the support 41. Figure 4 As shown, the support 41 is a groove-shaped structure, the groove bottom of the support 41 is connected to the second end of the support rod 20, and at least one roller 42 is arranged between two oppositely arranged groove walls of the support 41. A rotating shaft is arranged between the two groove walls of the support 41, and at least one roller 42 is rotatably arranged on the rotating shaft.

[0037] In some embodiments, the axis of the roller 42 is perpendicular to the extension direction of the support rod 20. The axis of the roller 42 in the embodiment of the utility model is perpendicular to the extension direction of the support rod 20, so that when switching the operating position, the roller device 40 can be pushed to rotate, so that the operator can push the reset operating device to move to other switching operating positions to further save effort.

[0038] In some embodiments, the operating rod 10 includes a first rod segment 11 and a second rod segment 12. The first end of the first rod segment 11 is connected to the clamping member 30. The second end of the first rod segment 11 is connected to the first end of the second rod segment 12. The second end of the second rod segment 12 forms an external force application end. The support rod 20 is connected to the middle of the first rod segment 11. The length of the second rod segment 12 is greater than the length of the first rod segment 11. Here, the length of the second rod segment 12 is set to be greater than the length of the first rod segment 11, and the support rod 20 is connected to the middle of the first rod segment 11, so that the operator's force arm is longer, and the operator's force is smaller.

[0039] The middle connection between the support rod 20 and the first rod segment 11 mentioned here refers to the connection between the support rod 20 and the middle part of the first rod segment 11. The middle part is not the midpoint of the first rod segment 11, but the connection between the other parts except the end.

[0040] In some embodiments, the angle between the first rod segment 11 and the second rod segment 12 is an obtuse angle. This arrangement enables the operator to complete the reset of the reset rod with a relatively small force.

[0041] like Figure 1 As shown, in some embodiments, the clamping member 30 includes a clamping plate 32 and a connecting plate 31 connected to the clamping plate 32. The clamping plate 32 has a clamping port 321, and the clamping port 321 is used to clamp the reset rod. The connecting plate 31 is used to connect with the operating rod 10. Such a configuration further increases the force arm of the applied force, thereby reducing the magnitude of the applied force and further saving effort.

[0042] In some embodiments, the plane where the connecting plate 31 is located forms an obtuse angle with respect to the plane where the clamping plate 32 is located. This arrangement further increases the force arm of the force, thereby reducing the magnitude of the force, and further saving effort. In addition, the connecting plate 31 is tilted toward the rear side, so that the connecting plate 31 will not have an adverse effect on the outward pulling of the reset rod.

[0043] Furthermore, since a sunshade, a rain shield, etc. are generally provided above the stop valve, the connecting plate 31 is arranged to be inclined toward the rear side to avoid positional interference between the reset operating device and the rain shield, etc.

[0044] From the above description, it can be seen that the reset operation device of the embodiment of the utility model reduces the force required to lift the reset rod according to the lever principle, which can effectively improve the reset efficiency and avoid safety hazards such as human body bumps and scratches during the reset process. In addition, during the reset process, the reset operation device can be used to apply the force required to lift the reset rod in a limited working space, thereby improving the reset efficiency and reducing safety hazards.

[0045] In some embodiments, a natural gas pipeline system includes a natural gas pipeline and the above-mentioned stop valve assembly. The stop valve of the stop valve assembly is arranged on the natural gas pipeline to control the flow of natural gas.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
