As shown in fig. 1 to 11(c), the valve status lock according to the embodiment of the present invention can be connected to a hidden rod valve 900 (shown in fig. 3 a), the hidden rod valve 900 includes a valve body 910, a valve rod 920 and a rotating wheel 930, the rotating wheel 930 is fixedly connected to the valve rod 920, and the valve rod 920 can control the valve body 910 to open or close by rotating the rotating wheel 930 (shown in fig. 3 b).

The above-mentioned built-in stem valve state lock includes the mounting unit 100 that can be connected to the valve body 910 of the built-in stem valve 900, the locking unit 200 (shown in fig. 1, 2, 3 a) for locking the runner 930 of the built-in stem valve 900, the lifting unit 310 that is driven to lift by the valve stem 920 when the valve stem 920 of the built-in stem valve 900 rotates, and the sensing unit 400 (shown in fig. 2, 4) for sensing the position of the lifting unit 310 to determine the open and close state of the built-in stem valve 900. The mounting member 100 may be a mounting base 110 fixedly coupled to the valve body 910, and the mounting base 110 may have a mounting positioning groove 111 matched with the valve body 910 and fixed to the valve body 910 by a screw 112 (shown in fig. 2). The locking part 200 may be coupled to the mounting part 100, and the sensing part 400 may be coupled to the locking part 200. The lifting component 310 can convert the circular motion of the valve rod 920 into lifting motion, the opening and closing state of the dark rod valve 900 can be detected by sensing the lifting position of the lifting component 310 through the sensing component 400, so that the opening and closing state of the dark rod valve 900 can be monitored, the blocking or unblocking of the rotating wheel 930 by the locking component 200 and the monitoring of the corresponding state are combined, the misoperation can be effectively prevented, and the safety and the reliability are high.

Specifically, the valve rod 920 or the rotating wheel 930 is fixedly connected with the rotating follower 320, and the rotating follower 320 can rotate synchronously with the valve rod 920 and the rotating wheel 930. The lifting member 310 includes a lifting stroke part 311 (shown in fig. 2) connected to the rotary follower 320 and axially moving relative to the valve rod 920 when the rotary follower 320 rotates, that is, when the valve rod 920 rotates in a forward/reverse direction, the lifting stroke part 311 may correspondingly lift/lower. The mounting member 100 is fixedly connected with a limit fixing seat 330 for limiting the rotation of the lifting stroke piece 311, a screw transmission structure can be adopted between the rotation follower 320 and the lifting stroke piece 311, and when the rotation follower 320 rotates, the lifting stroke piece 311 correspondingly ascends/descends (shown in fig. 3).

In this embodiment, the rotary follower 320 is a threaded sleeve 321 fixedly sleeved on the valve rod 920, and the lifting stroke member 311 is a stroke nut threadedly connected to the threaded sleeve 321. Of course, the rotary follower 320 and the lift stroke member may take other suitable configurations.

Specifically, the threaded sleeve 321 is connected with a locking ring 340 for locking the threaded sleeve 321 to the rotating wheel 930, the threaded sleeve 321 may be provided with a plurality of locking slots 322 for locking the spokes 931 of the rotating wheel 930, the threaded sleeve 321 is located at the bottom of the rotating wheel 930, the locking ring 340 is located at the top of the rotating wheel 930, the locking ring 340 and the threaded sleeve 321 may be fixed by screws 350, so that the threaded sleeve 321 may be fixed to the rotating wheel 930, and the valve stem 920 is fixedly connected to the rotating wheel 930, so that the threaded sleeve 321 may reliably rotate with the valve stem 920 and the rotating wheel 930 synchronously. Of course, the threaded sleeve 321 may be fixed to the valve stem 920 or the rotary wheel 930 by screws or other structures for specific applications.

Specifically, the limit fixing seat 330 has a limit cavity 331, and the stroke nut (the lifting stroke piece 311) is disposed in the limit cavity 331, so that the stroke nut can only move axially relative to the valve rod 920. The locking part 200 may be fixedly connected to the position-limiting fixing base 330 and located at one side of the position-limiting cavity 331.

Specifically, the limit fixing seat 330 may be sleeved on the valve rod 920 and fixedly connected to the mounting base 110 through a screw 360.

Specifically, the position of the lifting member 310 can be sensed between the sensing member 400 and the lifting member 310 by touch pressure sensing, magnetic sensing, photoelectric sensing or radio frequency sensing.

In this embodiment, the sensing part 400 includes a sensing switch assembly triggered by the lifting part 310 at different positions. The inductive switch assembly includes a first inductive switch 410 and a second inductive switch 420 disposed along a lifting direction of the lifting member 310, the lifting member 310 (travel nut) acts on the first inductive switch 410 when the dark bar valve 900 is in an open state, and the lifting member 310 (travel nut) acts on the second inductive switch 420 when the dark bar valve 900 is in a closed state. The first and second inductive switches 410 and 420 may be travel switches.

The first inductive switch 410 and the second inductive switch 420 are located at different positions with respect to the axial direction of the valve rod 920 for sensing different heights of the lifting member 310 during lifting, and the first inductive switch 410 and the second inductive switch 420 may be located on the same longitudinal axis or different longitudinal axes. Specifically, the first inductive switch 410 is located at a height that the lifting member 310 is located at in the valve-open state, and the second inductive switch 420 is located at a height that the lifting member 310 is located at in the valve-closed state. The lifting member 310 cannot simultaneously trigger the first and second sensing switches 410 and 420. That is, in the valve-open state, the lifting member 310 triggers only the first inductive switch 410; in the valve closed state, the lifting member 310 activates only the second inductive switch 420.

Specifically, the inductive switch assemblies (the first inductive switch 410 and the second inductive switch 420) are contact switch assemblies or inductive switch assemblies, that is, the lifting member 310 may trigger the contact switch assemblies through a contact pressing type or trigger the inductive switch assemblies through a non-contact type.

The locking rod 220 can be switched between an unlocking position and a locking position, when the locking rod 220 is in the locking position, the front end of the locking rod 220 extends out of the lock case 210 and forms a locking (blocking) with the rotating wheel 930, so that the rotating wheel 930 cannot rotate, i.e. the hidden rod valve 900 cannot be operated freely, thereby avoiding misoperation. When the locking lever 220 is in the unlocked position, the front end of the locking lever 220 retracts to release the limitation on the rotating wheel 930, and the rotating wheel 930 can rotate, so that a user can operate the non-rising stem valve 900 without affecting the normal operation of the non-rising stem valve 900.
