[0022] like Figures 1 to 7 As shown, the utility model provides a magnetic lock control valve, including a pipeline assembly and a valve assembly. The pipeline assembly includes a valve body 1, a spherical member 13, a valve stem 8 and a boss structure 9. A positioning pin 6 is fixedly connected to the top of the boss structure 9. A first magnetic steel 7 is elastically provided through the surface of the boss structure 9, so that the first magnetic steel 7 can extend in and out of the surface of the boss structure 9.

[0023] The valve assembly includes a valve switch 2 and a key 4, and the valve switch 2 and the key 4 are adapted to each other so that the key 4 can be normally buckled on the valve switch 2 to control the rotation of the valve switch 2. The inner top wall of the valve switch 2 is provided with a limit groove 12 adapted to the positioning pin 6 and a mounting hole 16 adapted to the valve stem 8. The opening angle of the limit groove 12 is 180°. The inner wall of the valve switch 2 is provided with a positioning groove 14 and a card groove 15 adapted to the first magnetic steel 7. When the valve switch 2 is installed on the valve body 1 , so that the top end of the positioning pin 6 is inserted into the limiting groove 12 and slides in the limiting groove 12, which is used to limit the rotation of the valve stem 8. At the same time, the first magnetic steel 7 can also slide on the inner wall of the valve switch 2, and when the first magnetic steel 7 is located at the positioning groove 14, the first magnetic steel 7 can automatically extend to be limited in the positioning groove 14. When the first magnetic steel 7 is away from the positioning groove 14 and slides on the inner wall of the valve body 1, it will squeeze the first magnetic steel 7 to extend into the boss structure 9, ensuring that the valve switch 2 can perform normal switching operation. , will not affect it. When the valve switch 2 is installed on the valve body 1, the valve stem 8 will be inserted into the mounting hole 16, which is used for the valve switch 2 to control the rotation of the valve stem 8. The inner wall of the key 4 is embedded with a second magnetic steel 11 corresponding to the first magnetic steel 7, and the second magnetic steel 11 and the first magnetic steel 7 are set at the same level. Through the setting of the above structure, when the user has not paid, the key 4 is buckled on the surface of the valve switch 2. At this time, the second magnetic steel 11 corresponds to the first magnetic steel 7. Using the principle of magnetic repulsion, one end of the first magnetic steel 7 will automatically extend into the boss structure 9. Then, the valve switch 2 is reversed by the key 4, so that the card slot 15 is reversed to the position corresponding to the first magnetic steel 7. At this time, the positioning pin 6 also rotates in the limit slot 12 until the rotation of the valve switch 2 is positioned so that it will not continue to rotate. Finally, the key 4 is removed from the valve switch 2, and the first magnetic steel 7 can be automatically ejected and positioned in the card slot 15, so that the user will not be able to rotate the valve switch 2 for use when the fee has not been paid.

[0024] like Figure 1 and Figure 3 As shown, two opposite turning handles 3 are fixedly connected to the surface of the valve switch 2, and guide grooves 5 adapted to the turning handles 3 are provided on the left and right sides of the key 4. Through the setting of the above structure, the valve switch 2 can be more accurately controlled to rotate by the key 4, and it is convenient for the user to rotate the valve switch 2 normally.

[0025] like Figure 2 and Figure 7 As shown, the spherical member 13 is arranged in the valve body 1, the bottom end of the valve stem 8 is connected to the top end of the spherical member 13, the boss structure 9 is fixedly connected to the surface of the valve stem 8, and the top end of the valve stem 8 extends to the top of the boss structure 9. The above structures are all existing mature technologies and adopt conventional connection methods in the existing technology, which will not be described in detail here.

[0026] like Figure 7 As shown, a spring 10 is fixedly connected to the surface of the valve stem 8, and one end of the spring 10 is connected to one end of the first magnetic steel 7. Through the setting of the spring 10, the first magnetic steel 7 has an elastic sliding effect on the surface of the boss structure 9, so that the first magnetic steel 7 can automatically extend into the boss structure 9 and squeeze the spring 10 when sliding on the inner wall of the valve body 1. When the first magnetic steel 7 is located at the positioning groove 14 and the clamping groove 15, one end of the first magnetic steel 7 is automatically extended due to the elastic force of the spring 10.

[0027] like Figure 3 As shown, the second magnetic steel 11 is provided in two groups, and the two groups of second magnetic steel 11 are symmetrical, which improves the practicality of the key 4 and eliminates the need for the staff to adjust the use angle of the key 4, thereby facilitating the staff to use the key 4 to lock the valve switch 2.

[0028] The working principle and use process of the utility model are as follows: when the user needs to lock the valve when he / she has not paid for a long time, he / she only needs to buckle the key 4 on the surface of the valve switch 2, so that the second magnetic steel 11 corresponds to the first magnetic steel 7, and one end of the first magnetic steel 7 will automatically extend into the boss structure 9 by using the principle of magnetic repulsion, and then the valve switch 2 is reversed by the key 4, so that the card slot 15 is reversed to correspond to the position of the first magnetic steel 7, and the positioning pin 6 is also rotated in the limit slot 12 until the rotation of the valve switch 2 is positioned so that it will not continue to rotate, and finally the key 4 is removed from the valve switch 2. When the valve switch 2 needs to be unlocked, the staff will buckle the key 4 on the valve switch 2 again. At this time, the second magnetic steel 11 will automatically bounce the first magnetic steel 7 back into the boss structure 9, further releasing the positioning of the first magnetic steel 7, and then the valve switch 2 is rotated forward by the key 4 to move the first magnetic steel 7 to the positioning slot 14.
