When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0035] In the related art, the handle and the pipe are tied together by ropes, but the ropes cannot ensure that the valves are effectively locked during maintenance or shutdown of the equipment. If the valve handle is accidentally touched, the position of the valve handle is still prone to change, posing a threat to personal and property safety.

[0036] In the related art, there is a technical problem that valves cannot be effectively locked. The embodiment of the present application provides a valve lock, which can at least to some extent solve the technical problem that valves cannot be effectively locked in the related art.

[0037] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0038] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the valve lock 100 is used to limit the handle 210 of the valve 200 and the pipe 300 where the valve 200 is located.

[0039] The valve lock 100 includes a connecting member 110 , a first clamping seat 120 , a second clamping seat 130 and a limiting member 140 .

[0040] The first clamping seat 120 and the second clamping seat 130 are fixedly connected by the connecting piece 110 , and the first clamping seat 120 and the second clamping seat 130 together form a pipe limiting hole 100 a of the limiting pipe 300 .

[0041] The limiting member 140 is installed on the connecting member 110 , and the limiting member 140 , the connecting member 110 and the first clamping seat 120 together form a handle limiting hole 100 b for limiting and positioning the handle 210 .

[0042] The first clamping seat 120 and the second clamping seat 130 are fixedly connected by a connector 110. When the first clamping seat 120 and the second clamping seat 130 are connected, the first clamping seat 120 and the second clamping seat 130 enclose a pipe limiting hole 100a. The pipe limiting hole 100a is used to limit the position of the pipe 300. When the valve lock 100 of the present application is used, the pipe 300 is located within the pipe limiting hole 100a.

[0043] It should be noted that the first clamp seat 120 and the second clamp seat 130 are detachably connected via the connecting member 110, so that the connecting member 110 can be removed from the first clamp seat 120 and the second clamp seat 130, so that the first clamp seat 120 and the second clamp seat 130 are separated, and further the first clamp seat 120 and the second clamp seat 130 can be removed from the pipe 300.

[0044] The stopper 140 is mounted on the connector 110. Together, the stopper 140, the connector 110, and the first clamping seat 120 define a handle stopper hole 100b. This hole 100b is used to position the handle 210. When the valve lock 100 of the present application is in use, the handle 210 is positioned within the hole 100b. The structure of the stopper 140 is diverse and is not limited herein.

[0045] like Figure 5 and Figure 6 As shown, after the present application is designed in this way, the pipeline 300 where the valve 200 is located is located in the pipeline limiting hole 100a, and the handle 210 of the valve 200 is located in the handle limiting hole 100b. Under the action of the valve lock 100, the handle 210 of the valve 200 remains relatively fixed with the pipeline 300. When the handle 210 of the valve 200 is accidentally touched, the handle 210 of the valve 200 is limited by the limiting member 140, the connecting member 110 and the first clamping seat 120, and the state of the handle 210 of the valve 200 will not change. When the equipment is overhauled or shut down, the valve 200 can be effectively locked, ensuring the life safety of the operator.

[0046] In some embodiments, a through hole 120a is provided on the first clamp seat 120 , and the connector 110 passes through the through hole 120a and is detachably connected to the second clamp seat 130 . The first clamp seat 120 is clamped between the second clamp seat 130 and the connector 110 .

[0047] The detachable connection between the connector 110 and the second clamping base 130 may be a snap connection, a threaded connection, etc. Figure 4 As shown, the through hole 120 a is a through hole that passes through the first clamping seat 120 , the connecting member 110 is located in the through hole 120 a , and the lower end of the connecting member 110 is detachably connected to the second clamping seat 130 .

[0048] After this design, the connecting member 110 passes through the first clamp seat 120 and is connected to the second clamp seat 130. After the connecting member 110 and the second clamp seat 130 are connected, the first clamp seat 120 is clamped by the connecting member 110 and the second clamp seat 130, which facilitates the connection of the connecting member 110, the first clamp seat 120 and the second clamp seat 130.

[0049] like Figure 4 As shown, in some embodiments, the connecting member 110 includes a first connecting portion 111 and a second connecting portion 112, the first connecting portion 111 passes through the first clamp seat 120 and is detachably connected to the second clamp seat 130; the first clamp seat 120 is clamped between the second clamp seat 130 and the second connecting portion 112; and the limiting member 140 is installed on the second connecting portion 112.

[0050] The first connection portion 111 and the second connection portion 112 are fixedly connected, and the second connection portion 112 is provided at one end of the first connection portion 111. Figure 4 As shown, the second connecting portion 112 is provided at the upper end of the first connecting portion 111. It should be noted that the size of the second connecting portion 112 is larger than the size of the through hole 120a, and the second connecting portion 112 cannot extend into the through hole 120a, so as to ensure that the second connecting portion 112 can contact the first clamping seat (120), so that the first clamping seat 120 can be clamped between the second clamping seat 130 and the second connecting portion 112. The first connecting portion 111 and the second connecting portion 112 can be fixedly connected by welding, bonding, clamping, etc.

[0051] In some embodiments, a threaded hole 130a is provided in the second clamp seat 130 at a position opposite to the through hole 120a; an external thread is provided on the end of the first connecting portion 111 away from the second connecting portion 112, and the first connecting portion 111 passes through the through hole 120a and is threadedly connected to the threaded hole 130a.

[0052] The threaded hole 130a and the through hole 120a are arranged relative to each other. After the first connecting portion 111 of the connecting member 110 passes through the through hole 120a, it extends into the threaded hole 130a and is threadedly connected to the threaded hole 130a. With this arrangement, the first connecting portion 111 of the connecting member 110 is passed through the through hole 120a and then rotated to thread the first connecting portion 111 and the second clamping seat 130 together. During the rotation of the first connecting portion 111, the second connecting portion 112 gradually approaches the first clamping seat 120 until the second connecting portion 112 contacts the first clamping seat 120, thereby clamping the second connecting portion 112 and the second clamping seat 130 to the first clamping seat 120.

[0053] In some embodiments, two connecting members 110 are provided, and the two connecting members 110 are arranged at intervals, and an avoidance hole 110a is provided on the connecting member 110; the limiting member 140 includes a connected insertion portion 141 and a limiting portion 142, and the limiting portion 142 is connected to one end of the insertion portion 141; the insertion portion 141 of the limiting member 140 is partially located in the avoidance hole 110a, the size of the limiting portion 142 is larger than the size of the avoidance hole 110a, and the limiting portion 142 is located outside the avoidance hole 110a.

[0054] In these embodiments, the insertion portion 141 of the limiting member 140 passes through the avoidance holes 110a of the two connecting members 110 in sequence. Since the size of the limiting portion 142 is larger than the size of the avoidance hole 110a, the limiting portion 142 will not be able to pass through the avoidance hole 110a. The limiting portion 142 is located outside the avoidance hole 110a, and the limiting portion 142 limits the insertion portion 141.

[0055] Specifically, the avoidance hole 110a is formed on the second connection portion 112 of the limiting member 140. When the insertion portion 141 of the limiting member 140 passes through the avoidance holes 110a of the two connecting members 110 in sequence, the second connection portions 112, the insertion portion 141 and the first clamping seat 120 of the two connecting members 110 are combined to form the handle limiting hole 100b.

[0056] In some embodiments, one end of the inserting portion 141 away from the limiting portion 142 extends out of the avoidance hole 110 a , and a mounting hole 141 a is defined at one end of the inserting portion 141 away from the limiting portion 142 .

[0057] like Figure 3As shown, the stopper 142 is located on the right side of the right connecting member 110. The left end of the insert 141 extends out of the left connecting member 110. The left end of the insert 141 is provided with a mounting hole 141a, which is located outside the avoidance hole 110a. The mounting hole 141a can be a through hole or a blind hole. With this design, the user can insert a pin or other object that can be inserted into the mounting hole 141a to limit the left end of the insert 141 and prevent the stopper 140 from sliding out of the mounting hole 141a.

[0058] In this way, the left end of the insertion part 141 is limited by the object located in the installation hole 141a, and the right end of the insertion part 141 passes through the limiting part 142, so that the limiting member 140 will not be detached from the connecting member 110, thereby improving the safety of the valve lock 100 of the present application.

[0059] In some embodiments, the valve lock 100 further includes a padlock 160 , which is installed in the installation hole 141 a .

[0060] In these embodiments, mounting hole 141 is a through hole. The structure of padlock 160 is well known to those skilled in the art and will not be described in detail here. Specifically, padlock 160 includes a locking beam and a locking tongue. The locking beam of padlock 160 passes through mounting hole 141a and engages with the locking tongue. This design allows operators to install padlock 160 in mounting hole 141a during maintenance or equipment shutdown, preventing other operators from removing the retaining member 140 or turning the handle 210, thereby enhancing the safety of valve lock 100.

[0061] In some embodiments, along the axial direction of the pipeline limiting hole 100a, the two connecting members 110 are respectively located on both sides of the pipeline limiting hole 100a.

[0062] like Figure 4 As described above, one connector 110 is located on the left side of the pipe stop hole 100a, and the other connector 110 is located on the right side of the pipe stop hole 100a. Along the axial direction of the pipe stop hole 100a, the two connectors 110 are located on either side of the pipe stop hole 100a, which helps to improve the stability of the connection between the first clamping base 120, the second clamping base 130, and the connectors 110.

[0063] The shape of the pipe stop hole 100a is not limited in this application and can be square, polygonal, elliptical, etc. In some embodiments, the pipe stop hole 100a is a circular hole. In these embodiments, semicircular holes of the same diameter are formed on the first clamping seat 120 and the second clamping seat 130. When the first clamping seat 120 and the second clamping seat 130 are connected by the connector 110, the two semicircular holes form a circular pipe stop hole 100a.

[0064] In some embodiments, the valve lock 100 further includes an elastic pad 150 , which is fixedly connected to the hole wall of the pipeline limiting hole 100 a .

[0065] The elastic pad 150 may be provided only on the first clamping seat 120, only on the second clamping seat 130, or on both the first clamping seat 120 and the second clamping seat 130. The elastic pad 150 is elastic and can be deformed under pressure. The material thereof may be silicone.

[0066] An elastic pad 150 is provided. After the first clamp seat 120 and the second clamp seat 130 are fixed by the connecting piece 110, the elastic pad 150 fits tightly against the outer wall of the pipe 300, which helps the first clamp seat 120 and the second clamp seat 130 to firmly clamp the pipe 300 and prevents the first clamp seat 120 and the second clamp seat 130 from rotating around the pipe 300 after the first clamp seat 120 and the second clamp seat 130 are fixed by the connecting piece 110, thereby ensuring the stability of the connection between the first clamp seat 120, the second clamp seat 130 and the pipe 300.

[0067] In some embodiments, two connecting members 110 are provided, and the two connecting members 110 are respectively provided on the first clamping seat 120 and the second clamping seat 130 .

[0068] The valve lock 100 of the present application can be used according to the following steps:

[0069] First, place the first clamping seat 120 and the second clamping seat 130 on both sides of the pipe 300, so that the pipe 300 is clamped between the first clamping seat 120 and the second clamping seat 130, and the handle 210 is located between the two through holes 120a;

[0070] Next, install the connecting member 110, hold the second connecting portion 112 of the connecting member 110, and allow the first connecting portion 111 to extend into the through hole 120a of the first clamping seat 120;

[0071] Next, the second connecting portion 112 is rotated so that the first connecting portion 111 is threadedly connected to the threaded hole 130a of the second clamping seat 130 until the second connecting portion 112 contacts the first clamping seat 120;

[0072] Next, install the limiting member 140, hold the limiting portion 142 of the limiting member 140, and make the insertion portion 141 pass through the two avoidance holes 110a in sequence, and make the installation hole 141a extend out of the avoidance hole 110a;

[0073] Finally, the padlock 160 is installed on the mounting hole 141 a. Specifically, the lock beam of the padlock 160 is passed through the mounting hole 141 a and engaged with the lock tongue.
