The rotating wheel 203 is axially locked and circumferentially rotatable arranged in the valve body 202. The valve core is circumferentially locked with the valve body 202 and movably arranged in the valve body 202 along the axial direction Z. The valve stem 201 is connected to the valve core. The rotating wheel 203 is configured to drive the valve stem 201 to move axially Z when rotating relative to the valve body 202, so as to drive the valve core to move axially Z.

[0041] The valve body 202 of the valve 20 is in communication with the pipeline which needs to be controlled to be opened or closed. One end of the valve stem 201 of the valve 20 is inserted into the valve body 202. The other end is located outside the valve body 202 and cooperates with the rotating wheel 203. The rotating wheel 203 rotates to drive the valve stem 201 to move along the axial direction Z, so as to drive the valve core to move along the axial direction Z, adjust the position of the valve core in the valve body 202, and control the opening degree of the valve 20. Exemplarily, the valve 20 is a gate valve.

[0042] In some embodiments, the rotating wheel 203 and the valve stem 201 are threadedly connected. The rotating wheel 203 is provided with an internal thread, and the valve stem 201 is provided with an external thread. The internal thread cooperates with the external thread to enable the valve stem 201 to move along the axial direction Z when rotating relative to the rotating wheel 203.

[0043] Please refer to Figure 3 and Figure 4 , Figure 3 the assembly drawing of the valve detection device 10, the valve stem 201 and the rotating wheel 203 provided by some embodiments of the present application; Figure 4An exploded view of a valve detection device 10 is provided for some embodiments of the present application. The valve detection device 10 is provided by an embodiment of the present application, the valve 20 includes a valve body 202, a valve stem 201 and a rotating wheel 203, the rotating wheel 203 is axially locked and circumferentially rotatable arranged in the valve body 202, the rotating wheel 203 is configured to drive the valve stem 201 to move axially Z when rotating relative to the valve body 202. The valve detection device 10 includes a detection assembly 1, a first adjusting bracket 2 and a second adjusting bracket 3. The detection assembly 1 includes a housing 11 and a detection part 12, the detection part 12 is rotatably arranged in the housing 11 about an axis extending along the axial direction Z, the detection assembly 1 is configured to detect the rotation angle of the detection part 12 when the detection part 12 rotates relative to the housing 11. The first adjusting bracket 2 is detachably connected to the housing 11, the first adjusting bracket 2 is used to detachably connect to the valve stem 201 to fix the housing 11 and the valve stem 201. The second adjusting bracket 3 is detachably connected to the detection part 12, the second adjusting bracket 3 is used to cooperate with the rotating wheel 203 to limit the second adjusting bracket 3 from rotating about the axis and allow the second adjusting bracket 3 to move along the axial direction Z.

[0044] The axial direction Z is the extension direction of the valve stem 201, one end of the valve stem 201 along the axial direction Z is inserted into the valve body 202 to cooperate with the valve core, the other end of the valve stem 201 along the axial direction Z is located outside the valve body 202, and the first adjusting bracket 2 is arranged close to the end of the valve stem 201 located outside the valve body 202. When the valve detection device 10 is assembled on the valve 20, the axial direction Z of the detection part 12 and the axial direction Z of the valve stem 201 are arranged in parallel or collinear. The extension direction of the axis is parallel to the axial direction Z.

[0045] The detection assembly 1 is used to detect the relative rotation angle between the rotating wheel 203 and the valve stem 201, so as to judge the opening degree of the valve 20. The detection part 12 can be rotatably arranged in the housing 11 about the axis; the detection part 12 and the housing 11 are axially locked, that is, the detection part 12 and the housing 11 cannot move along the axial direction Z, and remain relatively stationary in the axial direction Z.

[0046] The first adjusting bracket 2 connects the housing 11 and the valve stem 201 to fix the housing 11 and the valve stem 201. The fixing of the housing 11 and the valve stem 201 means that the housing 11 and the valve stem 201 cannot move relative to each other along the axial direction Z and cannot rotate relative to each other in the circumferential direction. The housing 11 and the first adjusting bracket 2 are detachably connected, which can be clamping, inserting, fastener connection and the like, wherein the fastener can be a bolt.

[0047] The second adjusting support 3 is connected to the detection part 12, so that the second adjusting support 3 and the detection part 12 can rotate synchronously. The second adjusting support 3 is detachably connected to the detection part 12, which can be clamped, inserted or fastened. The fastener can be a bolt. The second adjusting support 3 can be inserted or clamped with the rotating wheel 203. The rotating wheel 203 limits the rotation of the second adjusting support 3 around the axis, and the second adjusting support 3 and the rotating wheel 203 are circumferentially locked, so that the second adjusting support 3 can rotate synchronously with the rotating wheel 203. The rotating wheel 203 allows the second adjusting support 3 to move along the axial direction Z. When the rotating wheel 203 rotates, the valve rod 201 drives the detection assembly 1 to move along the axial direction Z, and the detection part 12 of the detection assembly 1 drives the second adjusting support 3 to move along the axial direction Z relative to the rotating wheel 203.

[0048] In the embodiments of the present application, the first adjusting support 2 is connected to the housing 11 and the valve rod 201, so that the housing 11 can move along the axial direction Z together with the valve rod 201. The second adjusting support 3 is connected to the detection part 12, and cooperates with the rotating wheel 203. On the one hand, when the rotating wheel 203 rotates relative to the valve rod 201, the rotating wheel 203 can drive the second adjusting support 3 to rotate, so that the detection part 12 connected to the second adjusting support 3 rotates relative to the housing 11 connected to the valve rod 201. Thus, the rotation angle of the detection part 12 relative to the housing 11 is measured to measure the rotation angle of the rotating wheel 203 relative to the valve rod 201, so as to determine the opening of the valve 20 and realize the opening detection of the valve 20. On the other hand, the first adjusting support 2 and the second adjusting support 3 realize the installation of the detection assembly 1 and the valve 20. When facing different models of valves 20, the first adjusting support 2 or the second adjusting support 3 can be replaced to adapt to the corresponding model of the valve 20, thereby improving the compatibility of the valve detection device 10, realizing the installation of the valve detection device 10 and the valve 20, improving the compatibility of the valve detection device 10, and reducing the manufacturing cost of the valve detection device 10.

[0049] In some embodiments, the detection assembly 1 further comprises a detection circuit board, a sensing element and a detection piece that is inductively coupled with the sensing element. The detection circuit board is arranged in the housing 11. The sensing element is arranged on the detection part 12 to rotate with the detection part 12. The detection piece is arranged on the detection circuit board. When the rotating wheel 203 rotates, the rotating wheel 203 drives the second adjusting support 3 to rotate, the second adjusting support 3 drives the detection part 12 to rotate, thereby driving the sensing element to rotate in the housing 11. The sensing element and the detection piece are inductively coupled, the detection piece sends a signal to the detection circuit board, thereby awakening the detection circuit board, so that the detection circuit board can receive the detection signal sent by the detection part 12, and further detect the process state of the valve 20.

[0050] In some embodiments, please refer toFigure 3 and Figure 4 The first adjusting bracket 2 comprises a mounting seat 21 and a clamping assembly 22.

By clamping the valve rod 201 through the clamping assembly 22, the installation difficulty of the first adjusting bracket 2 and the valve rod 201 is reduced, and the assembly of the first adjusting bracket 2 and the valve rod 201 is more convenient.
