[0029] Figure 1 Schematic diagram of an application scenario of a butterfly valve provided by an embodiment of the present disclosure. As Figure 1 shown, the butterfly valve 102 is installed on the pipeline 101. The butterfly valve 102 includes an operating handle 1021 and a valve body structure 1022; the operating handle 1021 is connected to the valve body structure 1022 to control the rotation of the valve body structure 1022. When the extending direction of the operating handle 1021 is the same as the extending direction of the pipeline 101, the valve body structure 1022 opens the pipeline 101 and is in a connected state; referring to Figure 1 , when the extending direction of the operating handle 1021 is perpendicular to the extending direction of the pipeline 101, the valve body structure 1022 blocks the pipeline 101 to make it in a closed state. The operating handle 1021 lacks a locking device, and anyone can change the position of the operating handle 1021, thereby changing the state of the pipeline 101, which brings great potential safety hazards to production safety.

[0030] In view of this, the present disclosure provides a locking tool for an operating handle of a butterfly valve. Specifically, the locking tool includes a first component 200 and a second component 300 (refer to Figure 2A , Figure 2B and Figure 3 ), the first component 200 includes a first body and a first locking portion 400, the first body can surround the outer periphery of the pipeline 101; the second component 300 includes a second body and a second locking portion 500, the second body can surround the outer periphery of the operating handle 1021, the second component can rotate with the rotation of the operating handle 1021, and the first locking portion 400 and the second locking portion 500 can cooperate to fix the rotating second locking portion to lock the position of the operating handle 1021. Adopting such a technical solution can lock the position of the operating handle, thereby improving production safety and avoiding personal injury.

[0031] The following will Figures 2A to 4 be combined with to detail the locking tool provided by the embodiments of the present disclosure.

[0032] Figure 2A FIG. shows a schematic structural diagram of a first component provided by an embodiment of the present disclosure. Figure 2B FIG. shows a schematic structural diagram of another perspective of a first component provided by an embodiment of the present disclosure. As Figure 2A and Figure 2B shown, the first component 200 includes a first body, a first locking portion 400 and a fixing member 203, and the first body can surround the outer periphery of the pipeline 202.

[0033] In some embodiments, the first body includes a first connecting plate 201 and a first connecting rod 202; the first connecting plate 201 and the first connecting rod 202 can be detachably connected by means of the fixing member 203; the first locking portion 400 is provided on the first connecting plate 201 (as Figure 2A shown).

[0034] In some embodiments, as Figure 2A shown, the first connecting plate 201 includes a surrounding plate 2011 and a first locking plate 2012, the first locking plate 2012 protrudes outward from the surrounding plate 2011 and the first locking portion 400 is provided on the first locking plate 2012. Here, the structure where the first locking plate 2012 protrudes outward from the surrounding plate 2011 facilitates the cooperation between the first locking portion 400 and the second locking portion 500.

[0035] Optionally, the first locking plate 2012 is perpendicular to the surrounding plate 2011. In other words, the first locking plate 2012 protrudes outward from the extension surface of the surrounding plate 2011. The first locking portion 400 is provided on the first locking plate 2012, and at this time, the surrounding plate 2011. Optionally, the first locking plate 2012 protrudes outward from the outer periphery of the surrounding plate 2011, and the first locking portion 400 is provided on the first locking plate 2012.

[0036] In some embodiments, the surrounding plate 2011 is provided with a first connection hole; when the first connecting rod 202 passes through the first connection hole, the fixing member 203 can fix the first connecting rod 202.

[0037] Exemplarily, the number of the first connecting plates 201 is two, the surrounding plate 2011 is a flat plate, and the number of the second connecting members 202 is at least two. As Figure 2A and Figure 2B shown, the two relatively arranged first connecting plates 201 are connected by using the second connecting member 202 and the fixing member 203, so that the surrounding plate 2011 and the second connecting member 202 form a structure capable of surrounding the pipeline 101. When the surrounding plate 2011 is arranged on the left and right sides of the pipeline 202, the first locking plate 2012 is perpendicular to the flat plate (as Figure 2A shown); when the surrounding plate 2011 is arranged on the upper and lower sides of the pipeline 202, the first locking plate 2012 protrudes from the outer periphery of the flat plate.

[0038] Exemplarily, the number of the first connecting plates 201 is one, the surrounding plate 2011 is a U-shaped plate, and the number of the second connecting members 202 is at least one. The first connecting plate 201 and the second connecting member 202 are fixedly connected by using the fixing member 203, and the U-shaped plate and the second connecting member 202 form a structure capable of surrounding the pipeline 101. When the bottom plate of the U-shaped plate is located on the lower side or the upper side of the pipeline, the first locking plate 2012 is parallel to the bottom plate of the U-shaped plate and protrudes from the outer periphery of the bottom plate.

[0039] Figure 3 The structure diagram of a second component 300 provided by an embodiment of the present disclosure is shown. As Figure 3 shown, the second body 300 includes a second connecting plate 301 and a third connecting plate 302 that are detachably connected; wherein, the second locking portion 500 is provided on the second connecting plate 301 or the third connecting plate 302 (not shown in the figure).

[0040] In some embodiments, the second connecting plate 301 includes a bearing plate 3011 and a second locking plate 3015; the second locking plate 3015 protrudes outward from the bearing plate 3011, and the second locking portion 500 is provided on the second locking plate 3015. Here, the structure in which the second locking plate 3015 protrudes outward from the bearing plate 3011 facilitates the cooperation between the first locking portion 400 and the second locking portion 500.

[0041] In some embodiments, the supporting plate 3011 includes a groove 3013 and a through hole 3014 ; the groove 3013 is used to support the operating handle; and the through hole 3014 is used to pass through the valve body structure 1022 of the butterfly valve.

[0042] In some embodiments, the carrier plate 3011 further includes a second connection hole 3012, and the third connection plate 302 includes a third connection hole 3022. When the second connection hole 3012 and the third connection hole 3022 are aligned, the carrier plate 3011 and the third connection plate 302 can be connected by fasteners, and the two can surround the operating handle 1021. It should be noted that when the carrier plate 3011 and the third connection plate 302 are aligned, the second locking plate 3015 protrudes beyond the boundary between the carrier plate 3011 and the third connection plate 302.

[0043] Furthermore, the second body 200 further includes a rotating assembly 303, which connects the second connecting plate 301 and the third connecting plate 302 and allows them to rotate relative to each other. The rotating assembly 303 helps control the relative position of the supporting plate 3011 and the operating handle 1021, preventing the supporting plate 3011 from sliding along the operating handle 1021.

[0044] Exemplarily, the supporting plate 3011 further includes a first rotation through-hole; the third connecting plate 302 includes a second rotation through-hole. The rotation assembly 303 includes a screw and a nut, with the screw passing through the first rotation through-hole and the second rotation through-hole and being threadedly connected to the nut. Thus, the third connecting plate 302 can rotate relative to the supporting plate 3011 around the screw. It should be noted that the first rotation through-hole is located on the side of the through-hole 3014 away from the groove 3013, so that the operating handle can extend outside the groove 3013. Optionally, the second connecting hole 3012 is located on the side of the groove 3013 away from the through-hole 3014. Such a structure helps to fix the second connecting plate 301 and the third connecting plate 302 more evenly and stably.

[0045] Optionally, the first locking portion 400 and the second locking portion 500 are respectively the first through hole and the second through hole. The locking tool further comprises a padlock (not shown in the figure), which can pass through and lock the relative positions of the first through hole and the second through hole.

[0046] Figure 4 The second component 300 and the butterfly valve assembly effect diagram provided by the embodiment of the present disclosure are shown. Figure 2A 、 Figure 2B and Figure 4 , the method of using the locking tool is explained by way of example.

[0047] First, follow Figure 2AAs described above, the first connecting plate 201 and the first connecting rod 202 are placed around the outer circumference of the pipeline 101 and fixed using the fixing member 203. Optionally, the first locking plate 2012 of the first connecting plate 201 is located on a side of the pipeline 101 close to the operating handle.

[0048] Next, if Figure 4 As shown, the second connecting plate 301 is inserted along the extension direction of the operating handle 1021, so that the valve body structure 1022 is located within the through-hole 3014, and the operating handle 1021 is partially located within the groove 3013 and partially extends outside the groove 3013. The third connecting plate 302 is rotated and connected to the second connecting plate 301 using the rotating assembly 303. When the second connecting hole 3012 and the third connecting hole 3022 are aligned, the carrier plate 3011 and the third connecting plate 302 are connected using fasteners.

[0049] It should be understood that the installation order of the first component 200 and the second component 300 can be adjusted, and the present disclosure does not limit this.

[0050] After the installation is completed, the operating handle 1021 is rotated, and the second component 300 rotates accordingly. When the operating handle 1021 is perpendicular to the pipe 101, the second locking portion 500 and the first locking portion 400 are aligned, and the padlock passes through the second locking portion 500 and the first locking portion 400 to lock the relative position of the two. At this time, the position of the operating handle 1021 is fixed (such as Figure 5 As shown), thereby avoiding misoperation by personnel and improving production safety. It should be noted that the first locking plate 2012 and the second locking plate 3015 at least partially overlap.

[0051] When the operating handle 1021 needs to be rotated, the padlock is opened with a key to release the lock between the second locking portion 500 and the first locking portion 400 .

[0052] The locking tool provided by the embodiment of the present disclosure is compact, easy to install, and has a wide range of applications.
