DETAILED DESCRIPTION

[0022] The technical scheme in the utility model is further explained below in combination with the drawings and embodiments.

[0023] As shown in the utility model embodiment, a double-encryption-locked filter ball valve is provided, which comprises: Figures 1-4

[0024] The ball valve body 1 is provided with a valve rod 2.

[0025] The encryption assembly comprises a rotating column 3, a limiting block 4, a clamping plate 5, a rotating block 9 and a secret key assembly. The rotating column 3 is internally provided with a movable cavity. The valve rod 2 is slidingly arranged through the bottom of the rotating column 3 and extends into the movable cavity. The limiting block 4 is fixedly arranged at the top of the valve rod 2. The limiting block 4 is provided with a positioning groove 6. The clamping plate 5 is fixedly arranged at the inner top of the movable cavity. The bottom and both sides of the clamping plate 5 are arc-shaped, so that the clamping plate 5 can be better inserted into the positioning groove 6, reducing the situation that the clamping plate 5 abuts against the limiting block 4. The positioning groove 6 is rectangular. The clamping plate 5 is inserted into the positioning groove 6 and cooperatively arranged. The clamping plate 5 abuts against the inner wall of the positioning groove 6, so that the clamping plate 5 can drive the limiting block 4 to rotate through the positioning groove 6. The inner top of the movable cavity is fixedly provided with a spring 7. The bottom of the spring 7 is fixedly provided with a circular ring 8. The clamping plate 5 is movably arranged through the spring 7 and the circular ring 8, without affecting the up-and-down movement of the clamping plate 5. The spring 7 can pop up the rotating column 3 upward through the circular ring 8, so as to drive the clamping plate 5 to move upward and separate from the positioning groove 6, thereby avoiding the ball valve body 1 from being opened or closed due to accidental touch, and further improving the safety.

[0026] The rotating block 9 is fixedly arranged at the top of the rotating column 3. The secret key assembly comprises a positioning block 10 and a rotating handle 13. The bottom of the positioning block 10 is provided with a clamping groove 11. The rotating block 9 is cooperatively arranged with the clamping groove 11, so that the rotating block 9 can be clamped into the clamping groove 11 and abut against the inner wall of the clamping groove 11, thereby enabling the positioning block 10 to drive the rotating block 9 to rotate through the clamping groove 11. The top of the positioning block 10 is fixedly provided with a fixing rod 12. The rotating handle 13 is fixedly arranged at the top of the fixing rod 12. The rotating handle 13 is convenient for the staff to rotate the positioning block 10.

[0027] The utility model also comprises a locking assembly, which comprises an L-shaped plate 14 and a sector plate 16. The L-shaped plate 14 is fixedly arranged on the ball valve body 1. The L-shaped plate 14 is provided with a first through hole 15. The sector plate 16 is fixedly arranged on the valve rod 2. The sector plate 16 is provided with two second through holes 17. When the ball valve body 1 is in a closed state, the first through hole 15 is aligned with one of the second through holes 17. When the ball valve body 1 is in an open state, the first through hole 15 is aligned with the other second through hole 17. The padlock is passed through the first through hole 15 and the corresponding second through hole 17, so that the sector plate 16 can be locked by the padlock, thereby locking the valve rod 2 and further locking the ball valve body 1. ​

[0028] The detailed working process of the utility model is as follows:

[0029] 1. When using, first, the positioning block 10 is sleeved on the rotating block 9, so that the rotating block 9 is clamped into the clamping groove 11, then the rotating handle 13 is pressed downward to the rotating column 3, the spring 7 is extruded, so that the clamping plate 5 is clamped into the positioning groove 6 (if the clamping plate 5 is not aligned with the positioning groove 6, the clamping plate 5 can be adjusted to be aligned with the positioning groove 6 by pressing and rotating), at this time, the valve stem 2 can be rotated by the rotating handle 13, and the ball valve body 1 is opened or closed;

[0030] 2. After the rotating handle 13 is loosened and the positioning block 10 is separated from the rotating block 9, the rotating column 3 is reset under the action of the spring 7, drives the clamping plate 5 to move upward and separate from the positioning groove 6, at this time, the valve stem 2 cannot be rotated, so that the ball valve body 1 is locked.

[0031] Finally, it is pointed out that the above embodiments are only used to illustrate the technical scheme of the utility model and are not limited. Although the utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical scheme of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the utility model technical scheme, and all should be covered in the scope of the claims of the utility model.
