[0033] like Figure 1-8 As shown, the valve is described in detail:

[0034] A valve comprises a main body tube 101, wherein a spherical groove 102 is provided in the middle of the inner diameter of the main body tube 101, and two plane grooves 105 are axially symmetrically provided on the inner wall of the main body tube 101, and a round seat 103 is provided on the outer surface of the main body tube 101 corresponding to the intersection of the two plane grooves 105 and the spherical groove 102, and round sleeves 303 are rotated in the two round seats 103, and a spherical disc 201 is rotated in the spherical groove 102, and end planes 204 are provided at the upper and lower ends of the spherical disc 201, and the two end planes 204 are respectively fitted and slid in the two plane grooves 105, and the two end planes 204 are respectively provided with a circular groove 203, and the two round sleeves 303 are respectively rotated in the two circular grooves 203, and a square hole 202 is penetrated by the spherical disc 201 between the two circular grooves 203, and a square block 301 is slidably fitted in the square hole 202, and a square rod 302 is provided at both ends of the square block 301.

[0035] The spherical disc 201 is located in the circular groove 203 and the inner hole of the circular seat 103 through the circular sleeve 303, forming a limited installation of the spherical disc 201 and the main tube 101, so that the spherical disc 201 can rotate with the circular sleeve 303 as the axis, and then the spherical disc 201 rotates in the main tube 101 to control the valve to open or close;

[0036] The outer edge of the spherical disc 201 is a spherical surface that matches the spherical groove 102. When the valve is closed, the spherical disc 201 contacts the spherical groove 102 through the edge spherical surface, and the two end planes 204 contact the two plane grooves 105 respectively, so that the valve maintains good sealing when it is closed.

[0037] At the same time, in order to better maintain the sealing performance, grooves are provided on the spherical surface of the spherical disc 201 and the end plane 204, and rubber strips are provided in the grooves (not shown in the figure). Therefore, when the valve is closed, the spherical disc 201 has a rubber strip between the edge spherical surface and the spherical groove 102, and a rubber strip is provided between the end plane 204 and the plane groove 105, so that the sealing performance of the valve is better.

[0038] Further:

[0039] An annular groove 205 is provided on the end plane 204 , and a rubber ring is provided in the annular groove 205 , so that the gap between the valve and the circular groove 203 and the circular sleeve 303 is isolated and sealed by the rubber ring.

[0040] like Figure 1-8 As shown:

[0041] A circular seat 401 is sleeved on each of the two round seats 103 . A square groove 402 is provided at the center of the circular seat 401 , and an electromagnet is provided in the square groove 402 . A socket 404 is provided on the side of the circular seat 401 , and an electric plug hole 405 is provided on the socket 404 .

[0042] An extension plate 403 is disposed at the end of the annular seat 401 away from the socket 404 .

[0043] The extension plate 403 is provided with a sheath.

[0044] The two annular seats 401 are clamped on the two round seats 103 through the clamping spring. When the valve needs to be controlled to be opened or closed, the power cord is first inserted into the plug hole 405 to power the electromagnet, thereby generating a magnetic force to attract the square rod 302 to slide in the direction of the electromagnet and then insert it into the square groove 402. Then, by twisting the extension plate 403, the square rod 302 is driven to rotate, and then the block 301 drives the spherical disc 201 to rotate, thereby controlling the valve to be opened or closed;

[0045] Further:

[0046] The end of the circular sleeve 303 away from the spherical disc 201 is provided with a threaded ring, which is threadedly connected to the inner hole of the circular seat 103 . Springs I 304 are respectively provided between the two ends of the block 301 and the two circular sleeves 303 .

[0047] The threaded ring on the round sleeve 303 and the inner thread of the round seat 103 form a fixed installation of the round sleeve 303, and then the spherical disc 201 and the main tube 101 are installed. Then, through the elastic force of the two springs I 304, the square block 301 can be pushed to the center of the square hole 202 at the same time, so that the two square rods 302 are located in the two round sleeves 303 and will not be automatically inserted into the square groove 402, thereby ensuring that when the round ring seat 401 is not powered, the valve cannot be controlled to open or close;

[0048] This effectively prevents non-professionals from manipulating the valve;

[0049] Moreover, in order to further prevent non-professionals from manipulating the valve, the power plug hole 405 can be designed to be a triangle, square or other special shapes, so that non-professionals cannot supply power to the ring seat 401, thereby ensuring that non-professionals are prevented from manipulating the valve.

[0050] Further:

[0051] A baffle frame 406 is slidably passed through the socket 404 , and a spring II 407 is provided between the baffle frame 406 and the socket 404 , so that the baffle frame 406 can shield the power plug hole 405 .

[0052] The elastic force of spring II 407 pushes the baffle frame 406 to press against the socket 404 and shield the plug hole 405 to prevent dust from falling into the plug hole 405 and affecting the electrification of the electromagnet in the annular seat 401;

[0053] When the valve needs to be controlled to be opened or closed, the baffle frame 406 is directly moved to expose the power plug hole 405 .

[0054] Further:

[0055] The two ends of the main tube 101 are both provided with thread grooves 104 , and the two thread grooves 104 are both threadedly connected with extension tubes 501 . The extension tubes 501 are provided with flanges 502 at the ends away from the main tube 101 .

[0056] By providing the extension pipe 501 and the flange 502, the connection mode at both ends of the valve can be replaced from threaded connection to flange connection, thereby increasing the connection forms and facilitating the use of the valve.

[0057] like Figure 1-8 As shown:

[0058] A valve production process, assembling the valve, comprising:

[0059] S1, take the spherical disc 201 and place it on one end of the main tube 101, and make the spherical disc 201 and the end surface of the main tube 101 perpendicular to each other;

[0060] S2, making the two end planes 204 of the spherical disc 201 slide along the two plane grooves 105 toward the center of the main tube 101, until the circular groove 203 corresponds to the inner hole of the round seat 103;

[0061] S3, insert the round sleeve 303 into the round groove 203 through the inner hole of the round seat 103 to limit the spherical disc 201 and the main tube 101, and then insert the square block 301 into the square hole 202;

[0062] S4. By rotating the square rod 302, the valve can be controlled to open or close.
