Examples

With reference to fig. 1-3, a circular truncated cone at the top of the valve body 11 is matched with the locking assembly 2, and the locking assembly 2 can be sleeved on the circular truncated cone to rotate freely. The circular groove of the locking assembly 2 is concentric with the circular truncated cone at the top of the valve body 11, so that the locking assembly 2 is not easy to lose position during working, and the working stability of the locking assembly 2 can be ensured. The slot 14 and the valve body lock hole 15 serve to restrain the first steel pin 21 and the second steel pin 24, which in turn restricts the rotation of the latch assembly 2 and the spool. The first steel pin 21 is fixedly connected with a third magnetic steel 22, and is elastically connected with the locking component 2 through a first elastic element 23, so that the position of the first steel pin 21 can be controlled by the magnetic force and the elastic force of the first elastic element 23. When the first steel pin 21 is located in the groove 14, the valve core can be opened and closed automatically by using a handle; when the first steel pin 21 is positioned in the valve body lock hole 15, the valve is in a locking state. Because the first magnetic steel 31 and the third magnetic steel 22 attract each other and the second magnetic steel 31 and the fourth magnetic steel 25 repel each other, after the key 3 is sleeved into the locking assembly 2, the first steel pin 21 moves upwards and exceeds the surface plane of the groove 14; the fourth magnetic steel 25 presses the second steel pin 24 into the valve body lock hole 15, and at the moment, the locking assembly 2 can rotate to a state that the first steel pin 21 is located in the limiting hole 16, so that the valve locking is realized. The steel pin structure parallel to the valve rod can greatly save the space occupied by the valve, the first limiting part 27 is parallel to the valve rod, the first elastic element 23, the third magnetic steel 22 and the first steel pin 21 in the first limiting part are also placed, and the third magnetic steel 22 and the first steel pin 21 move back and forth in the first limiting part 27. The movement requires a certain stroke, and if the locking assembly 2 is placed perpendicular to the valve stem, the design is large enough to accommodate the entire movement. The diameter of the locking assembly 2 can be reduced by placing the locking assembly parallel to the valve rod instead of perpendicular to the valve rod, and the occupied area of the whole structure is reduced, so that the occupied space of the whole valve is reduced, and the valve can adapt to more environments needing valves with small volumes. The first steel pin 21 thus designed, however, is positioned parallel to the valve stem, so that the first magnetic steel 31 is located on the top of the locking assembly 2 instead of on the side when the key 3 is inserted into the locking assembly 2. Therefore, when in operation, the worker can conveniently identify the positions of the marks corresponding to the first magnetic steel 31 and the first limiting part 27, and the operation is more convenient.

The second steel pin 24 and the fourth magnetic steel 25 are cylindrical and are positioned in the second limiting part 28 and the valve body lock hole 15. The second steel pin 24 and the fourth magnetic steel 25 do not have a connection relation, when the valve state is switched, the fourth magnetic steel 25 pushes the second steel pin 24 into the valve body lock hole 15, the second steel pin 24 and the valve body lock hole 15 need to move up and down in the second limiting part 28 and the valve body lock hole 15, the cylindrical shape can be free of the influence of angle rotation, and the passing rate during movement is improved. The external handle can be detached when the valve works, so that the occupied space of the valve is saved, and the valve rod and the valve core 13 are rotated in a labor-saving manner when the valve needs to be operated, so that the valve is opened and closed.

The working principle is as follows:

freely opened and closed state (fig. 1): the first steel pin 21 is positioned in the groove 14 of the valve body 11, and the locking assembly 2 can reciprocate 90 degrees under the limit of the first steel pin 21, so that the opening or closing of the ball valve is realized.

Locked state (fig. 2): when the locking assembly 2 is at this position, the first steel pin 21 is located in the limiting hole 16 of the valve body 11, and the valve is in a locking state and cannot rotate. The first steel pin 21 is arranged in the limiting hole 16 to realize the locking of the valve.

Switching between the free opening and closing state and the locking state: the key 3 is sleeved on the locking component 2 (as shown in fig. 2), and because the first magnetic steel 31 and the third magnetic steel 22 are opposite in attraction, and the first magnetic steel 31 is fixedly connected with the first steel pin 21, the first magnetic steel 31 drives the first steel pin 21 to move upwards, and the first steel pin 21 leaves the groove on the valve body 11; the second magnet 32 repels the fourth magnet 25 in like polarity, and the fourth magnet 25 moves downward, pressing the second steel pin 24 away from the second position-limiting member 28 of the locking assembly 2. The valve handle is now free to rotate, and in the condition of fig. 1, the key 3 is removed, and the first steel pin 21 springs into the groove 14 under the action of the first elastic element 23, and the valve is free to open and close. When the key 3 is taken down in the state shown in fig. 2, the first steel pin 21 springs into the valve body lock hole 15 under the action of the first elastic element 23, and the second steel pin 24 springs into the limiting hole 16 under the action of the second elastic element 26, so that the valve locking effect is achieved.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
