Embodiment
Explanation is further described to the technical solution of the utility model below by specific embodiment.
Embodiment：
As shown in Figure 1, Figure 2, Figure 3 shows：A kind of electrical ball valve, including valve body 1, be connected to the bonnet 2 at the top of valve body 1 and be located at
The drive mechanism 3 of the upside of bonnet 2, the valve body 1 interior valve seat 4 and rotary seal provided with ring-type are arranged on the valve ball in valve seat 4
5, hollow valve pipe 6 is installed, the inside of valve pipe 6 is provided with valve tube chamber 7, and the bottom of valve pipe 6 is located at valve tube chamber 7 on bonnet 2
It is interior to be provided with headstock gear 8；Headstock gear 8 includes drive seat 9, and its center basic point is located on the central shaft of valve pipe 6, the drive seat 9
The air line distance at both ends is slightly less than the internal diameter of valve pipe 6, avoids the friction of drive seat 9 and valve inside pipe wall；Also include drive shaft 10, drive
The upper end of moving axis 10 is connected with drive mechanism 3, and lower end is arranged on the center of drive seat 9, is driven in the presence of drive mechanism 3
Moving axis 10 rotates, and drive seat 9 is rotated in valve tube chamber 7；The side of the valve seat 4 away from valve ball 5 is set
The gasket ring 12 for having the elastomeric bladder 11 of annular and matching with elastomeric bladder 11, gasket ring 12 are sandwiched between elastomeric bladder 11 and valve seat 4, gasket ring 12
It is fixedly connected with valve seat 4.
As shown in Figure 1 and Figure 2：The inwall of valve pipe 6 is provided with two locating parts 13 for being used to coordinate drive seat 9 to rotate, limit
Position part 13 is located at same level with drive seat 9, and the drive seat 9 drives between locating part 13 when drive shaft 10 drives
After the rotation of seat 9 to locating part 13, valve pipe 6 rotates together under the drive of drive seat 9.
As shown in Figure 1, Figure 3：The gasket ring 12 is provided with push rod 14, is provided with the valve body 1 and accommodates the activity of push rod 14
Chamber 15 is pushed away, the outer wall of valve pipe 6 is provided with four perforates 16 for matching and being set at 90 ° intervals with the termination of push rod 14, and valve closes
