[0026] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0027] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example:

[0030] See also Figure 1 This embodiment discloses an interlocking valve assembly, including a valve body 10 and a lock body 20. The number of valve bodies 10 and lock bodies 20 is multiple and equal, and each valve body 10 matches one lock body 20.

[0031] Specifically, the valve body 10 includes a valve stem 11 , which drives the valve body 10 to open and close. A lock body 20 is matched on each valve stem 11 .

[0032] A keyhole 21 is provided at each end of the lock body 20. A key can be inserted into each of the two keyholes 21. Moreover, the lock body 20 is in an open state only when a key is inserted into both keyholes 21. Therefore, only when a key is inserted into both keyholes 21 of the lock body 20 can the corresponding valve stem 11 move, and at this time the opening and closing state of the valve can be controlled.

[0033] All the lock bodies 20 have a key hole 21 in common, that is, one of the key holes 21 in all the lock bodies 20 can use the same key to drive the lock cylinder 23 therein.

[0034] In this embodiment, when keys are provided, the number of keys is one more than the number of all lock bodies 20, so that one key can only be inserted into one lock body 20 at a time, resulting in a state where only one lock body 20 has two keys, thereby causing the other lock bodies 20 to be in a locked state.

[0035] Therefore, through this technical solution, all valve bodies 10 can be linked, that is, when the valve stem 11 of one valve body 10 is movable, the other valve stems 11 are in an immobile state.

[0036] In a specific implementation of this embodiment, there are two valve bodies 10 and two lock bodies 20, and there are three keys. The two lock bodies 20 are V1 and V2, the two keyholes 21 on V1 are H1 and H2, the two keyholes 21 on V2 are H3 and H4, and the three keys are K1, K2 and K3.

[0037] In the initial state, both V1 and V2 are in a closed state, a key K1 is inserted into the keyhole H1 of the lock body V1, a key K3 is inserted into the keyhole H3 of the lock body V2, and both the key K1 and the key K3 cannot be removed.

[0038] At this time, if the lock body V1 needs to be opened, the key K2 is inserted into the keyhole H2 of the lock body V1, so that the lock body V1 is in the open state, and the valve body 10 and the valve stem 11 corresponding to the lock body V1 are in a movable state, and then the valve stem 11 can be driven to make the valve body 10 in the open or closed state.

[0039] Then, if the lock body V2 needs to be opened, the key K1 in the keyhole H1 of the lock body V1 is pulled out, and then the key K1 is inserted into the keyhole H4 of the lock body V2, so that the lock body V2 is in the open state, and the valve body 10 and the valve stem 11 corresponding to the lock body V2 are in the movable state, and then the valve stem 11 can be driven to make the valve body 10 in the open or closed state.

[0040] After the key K1 is pulled out of the keyhole H1 of the lock body V1 , the lock body V1 is in a closed state, and the valve body 10 and the valve stem 11 corresponding to the lock body V1 cannot be driven.

[0041] Generally, after adjusting the opening and closing states of the two valve bodies 10 , one of the keys is placed in a designated location (such as a key cabinet). Next time when the states of the two valve bodies 10 need to be adjusted, the key is taken out and the above adjustment is performed.

[0042] In one specific embodiment:

[0043] See also Figure 2 The lock body 20 includes a shell 22, a lock core 23 and a pressure block 24, wherein a channel 25 is provided in the middle of the shell 22, and the valve stem 11 of the valve body 10 passes through the channel 25. The action part of the lock body 20 is the pressure block 24, which is dynamically connected to the lock core 23. The pressure block 24 can be driven to move by rotating the lock core 23.

[0044] The pressure block 24 is located on the side of the channel 25. When the lock cylinder 23 is rotated, the pressure block 24 moves away from the channel 25. When the key is withdrawn from the lock cylinder 23, the lock cylinder 23 automatically rebounds or can only be withdrawn after the key is rotated to the specified position. The lock cylinder 23 can drive the pressure block 24 to move to the channel 25 again.

[0045] Since the valve stem 11 passes through the passage 25 , the side of the pressing block 24 contacts the valve stem 11 , thereby controlling the valve stem 11 through frictional force, so that the valve stem 11 cannot rotate.

[0046] The pressing block 24 is provided with pressing teeth, and a corresponding tooth structure is provided on the surface of the valve stem 11 . The pressing teeth and the tooth structure can prevent the valve stem 11 from sliding.

[0047] In addition, a pressure block 24 is provided on both sides of the channel 25. The two pressure blocks 24 constitute a clamping assembly, and the valve stem 11 is clamped from both sides of the valve stem 11. At the same time, the two pressure blocks 24 correspond to the lock core 23 in a keyhole 21 respectively, so that when there is a key in only one keyhole 21 of the lock body 20, the lock body 20 is still in a closed state.

[0048] In another specific embodiment:

[0049] The valve body 10 also includes a valve core 12 and a housing 13. The valve stem 11 is rotatably mounted on the housing 13, and the valve core 12 and the valve stem 11 are threadedly connected. The outer shell 22 of the lock body 20 is detachably connected to the housing 13 of the valve body 10. The medium flow direction of the valve body 10 is perpendicular to the length of the valve stem 11. The housing 13 has an S-shaped channel 25 in the middle, and the valve core 12 can be cut off in the middle of the channel 25.

[0050] By detachably connecting the lock body 20 to the housing 13 of the valve body 10 , it is ensured that the lock body 20 will not move along with the valve stem 11 when the lock body 20 locks the valve stem 11 .

[0051] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
