[0002] An electric ball valve is a valve body whose ball is driven by a motor to rotate around the axis of the valve stem. It is mainly used in industrial automation control systems and is composed of an electric actuator and a ball valve as an important actuator for pipeline pressure components. The opening and closing parts (ball) of this type of electric ball valve are driven by the valve stem, and are equipped with a valve that rotates around the axis of the valve stem. It is usually used for remote opening and closing (connecting and cutting off the medium) control of pipeline media. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. It is particularly suitable for media containing fibers, tiny solid particles, etc. It has a strong shear force, and the change of the valve seat opening is directly proportional to the valve disc stroke.

However, the above-mentioned products and similar products lack internal switch settings, which makes it difficult to track and monitor the working status in real time, and the overall assembly production is relatively inconvenient, and the sealing and overall firmness of the connection parts need to be further improved; at the same time, the ball of the above-mentioned product is fixed by the upper and lower pressure plates, which is easy to produce eccentricity, and the seal has no oil storage groove and dustproof paddle.

[0028] The valve ports on both sides of the above-mentioned valve body are respectively provided with a first valve port part 4 and a second valve port part 18. The first valve port part and the second valve port part are respectively connected by rotating and buckling with the raised reverse heads of the outer diameter at the valve ports on both sides through the outer diameter reverse hook columns. At the same time, the reverse heads at the valve ports on both sides of the valve body are respectively provided with corresponding raised stop heads 200, and the barb columns on the first valve port part and the second valve port part corresponding to the stop heads are provided with raised limit heads 100, and the stop heads are abutted against the limit heads; a valve port sealing ring 3 is provided at the connection between the first valve port part and the valve body, and a valve port sealing gasket 17 is provided at the connection between the second valve port part and the valve body, and a bevel ring on one side of the valve port sealing gasket is clamped and fixed between the second valve port part and the valve body, and a step ring on the other side of the valve port sealing gasket is abutted and sealed against the bevel on one side of the circular contact surface of the sphere, and the step ring on the sphere side of the sealing gasket is provided with an oil storage groove and a dust-proof pick.

[0030] In summary, the specific structural features of the built-in ball valve are as follows: 1. The built-in ball valve includes a valve body, a valve port, a valve port seal, a ball, a positioning shaft, a speed reduction cover plate assembly, a drive shaft, a switch assembly, a speed reduction gear assembly, a motor assembly, and a motor cover. The above corresponding components are fixed by rotating and buckling with the inverted buckle and the inverted hook. 2. The output gear is connected to the drive shaft as a whole. 3. The switch assembly is provided with a bidirectional movable spring and two fixed springs. 4. The convex head of the output gear is pressed to the left to close the movable spring and the fixed spring of the switch assembly to the open valve state. 5. The convex head of the output gear is pressed to the right to close the movable spring and the fixed spring of the switch assembly to the closed valve state. 6. The limit block at the top of the drive shaft is installed in the ball groove at the lower end of the ball. 7. There is a boss on each side of the lower end of the ball, and two limit ribs are provided inside the valve body. When the ball performs the switch valve action inside the valve body, after the switch valve is in place, the limit rib of the valve body will clamp the ball boss to prevent the ball from turning over, thereby playing a limiting role. 8. After the locating shaft is installed into the valve body, the two beveled elastic buckles on the valve body will clamp the locating shaft to ensure that the locating shaft will not fall out. 9. The locating shaft and the drive shaft are aligned up and down, and are assembled with the ball in an inserting manner to ensure that the upper and lower positions of the ball always remain concentric. 10. When the locating shaft and the valve body are assembled, a sealing ring is provided to ensure sealing. 11. The overall structure of the valve body adopts a rotating buckle structure, and a limit block is provided to prevent the rotating buckle from rotating back. 12. The sealing surface of the valve port sealing gasket and the valve body and valve port adopts an italic structure, which will have a better sealing effect. 13. A groove is provided at the place where the valve port sealing gasket and the circular contact surface of the ball abut each other. When the ball is performing the switch valve action, the oil squeezed by the rotation is blocked in the sealing gasket to reduce loss. The contact surface between the valve port sealing gasket and the ball has a dustproof table. 14. There is a circle of bosses on the sealing surface of the deceleration cover and the cover gasket. After the valve body and the deceleration cover are assembled, the existence of the bosses makes the gasket firmly fixed in the middle, and the cover gasket and the drive shaft are tightly wrapped to ensure sealing. 15. The assembly of the valve body and the deceleration cover adopts an internal rotating buckle structure. The valve body buckle is first inserted into the notch of the deceleration cover, then rotated into the buckle groove, and then the limit buckle locks them. 16. The switch assembly has a two-way moving spring and two fixed springs, so only three contacts are required. 17. There are three barbed buckles at the lower end of the gear fixing plate to firmly fix the motor. 18. The buckle fitting surface of the motor cover and the deceleration cover is inversely beveled, which ensures the reliability of the assembly. 19. There is a gap groove on the internal interface between the motor cover and the deceleration cover, where a sealing ring is provided to ensure internal sealing. 20. There is a wire outlet hole in the motor cover cavity. The motor wire and the switch wire pass through the sealing plug and then pass out from the wire outlet hole. Then the sealing plug is plugged into the wire outlet hole to ensure sealing. 21. There are three ribs on the motor cover where the motor cover and the speed reducer cover are buckled.
