[0033] The specific working process of the integrated intelligent heating ball valve is as follows:

[0034] When the ball valve controls the heating pipeline to be closed, the staff rotates the hand wheel 14, so that the hand wheel 14 drives the valve core 9 to rotate ninety degrees through the valve stem 7, and then the outer surface of the valve core 9 blocks the valve seat 10, as shown in Figure 4 In this process, since the valve core 9 rotates ninety degrees, the first magnetic ring 91 on the valve core 9 is just rotated to the magnetic field range of the second magnetic ring 103, and then the first magnetic ring 91 is used to adsorb the second magnetic ring 103, so that the sealing ring 102 is attached to the outer surface of the valve core 9, even if the outer surface of the valve core 9 is worn, since the sealing ring 102 is attached to the valve core 9, the valve cannot be tightly closed and the medium cannot be leaked, the sealing property of the valve is improved; At the same time, when the valve core 9 rotates to close the valve, since the first magnetic ring 91 adsorbs the second magnetic ring 103, the sealing ring 102 can be quickly attached to the outer surface of the valve core 9, so as to accelerate the closing of the valve core 9.

[0035] Secondly, when the ball valve controls the heating pipeline to be opened, the staff reversely rotates the hand wheel 14 by ninety degrees, and then the valve stem 7 drives the valve core 9 to rotate, so that the through hole 11 on the valve core 9 connects the inlet pipe 2 and the outlet pipe 4, in this process, the rotation of the valve core 9 makes the protrusion 92 on the valve core 9 first contact the edge of the sealing ring 102, so as to push the sealing ring 102 open, and then the medium pressure in the valve body 1 promotes the sealing ring 102 to move quickly to the direction of the valve seat 10, at this time, the bellows 101 is retracted, so that the valve can be quickly opened.

[0036] Compared with the prior art, the utility model discloses a corrugated pipe, sealing ring, first magnetic ring and second magnetic ring are designed, when the valve is closed, the valve stem drives the valve core to rotate, makes the valve core rotate ninety degrees, first magnetic ring on the valve core just rotates to the magnetic field range of second magnetic ring, and then utilizes second magnetic ring to adsorb first magnetic ring, makes sealing ring to be attached on the outer surface of valve core, even if the outer surface of valve core appears abrasion, because of the fit of sealing ring and valve core, will not appear that the valve is not tight and medium leaks, improved the sealing of valve.

[0037] When the valve core rotates and closes the valve, because second magnetic ring adsorbs first magnetic ring, can make sealing ring quickly attach on the outer surface of valve core, thereby accelerates the closing of valve core.

[0038] When the valve needs to open, the rotation of valve core makes the convex block on valve core first contact with the edge of sealing ring, thereby toping open sealing ring, and then utilizes the medium pressure in valve body to make sealing ring move to the direction of valve seat, at this time, the corrugated pipe retracts, so that the valve can realize quick opening.
