The limiting extrusion frame 212 is slidably mounted on two limiting extrusion frame sliding rods 211 which are arranged in parallel, the two limiting extrusion frame sliding rods 211 are fixedly mounted on the electromagnet 210, the electromagnet 210 is magnetically matched with the limiting extrusion frame 212, the electromagnet 210 is fixedly mounted on the inner fine tuning shell 207, and an elastic component 213 is arranged between the inner wall of the inner fine tuning shell 207 and one side surface, away from the electromagnet 210, of the limiting extrusion frame 212. A trimming motor support plate 208 is fixedly installed on one side, far away from the driving valve column 1042, of the inner trimming housing 207, a trimming motor 209 is fixedly installed on the trimming motor support plate 208, and an output shaft of the trimming motor 209 is fixedly connected with the sun gear 217.
First, the micro-adjustment motor 209, the driving motor 206 and the electromagnet 210 are connected with a remote control unit, so as to remotely control the rotation angles of the micro-adjustment motor 209 and the driving motor 206, and the start-stop state of the electromagnet 210, when fluid is required to pass through the valve core 104, the driving motor 206 is controlled, the output shaft of the driving motor 206 drives the driving gear 203 to rotate, the driving gear 203 rotates to drive the driving gear 202 to rotate, the driving gear 202 rotates to drive the valve core 104 to rotate (the flow channel 1041 and the driving valve column 1042 are part of structures on the valve core 104), the flow channel 1041 is rotated to an angle coaxial with the first valve body 101 and the second valve body 102, or an angle difference exists, and the size of the angle between the flow channel 1041 and the axes of the first valve body 101 and the second valve body 102 determines the size of the passing flow (all adjustment limiting plates 114 cannot be blocked at this time). The size of the passing flow rate can also be adjusted by controlling the adjustment limiting plate 114 to move from the position shown in fig. 7 to the position shown in fig. 8. Specifically, the trimming motor 209 is controlled, the output shaft of the trimming motor 209 drives the sun gear 217 to rotate, the sun gear 217 rotates to drive the planetary gear 216 to rotate, and the planetary gear 216 rotates to drive the planetary gear carrier 218 to rotate, where the premise is that the outer ring gear 215 is fixed (it should be noted that, when the trimming motor 209 is started, the electromagnet 210 is also energized, and the electromagnet 210 generates magnetic force after being energized, so as to attract the limiting extrusion frame 212, the elastic component 213 is in a stretched state, and then the limiting extrusion frame 212 extrudes the limiting convex tube 2141, so that the limiting convex tube 2141 cannot rotate, the limiting disc 214 cannot rotate due to the fact that the limiting disc 214 and the outer ring gear 215 are fixed, and therefore the outer ring gear 215 cannot rotate). The planetary gear carrier 218 rotates to drive the fine adjustment input gear 219 to rotate, the fine adjustment input gear 219 rotates to drive the central driving gear 220 to rotate, the fine adjustment driving gear 110 drives the fine adjustment driving gear ring 111 to rotate through the transmission rod shaft 108, the fine adjustment driving gear ring 111 drives the adjustment rotary table 109 to rotate, the sliding pin 113 is shifted to move along the hexagonal sliding rail through the shifting chute 1091, the adjustment limiting plates 114 at the moment synchronously move, and the size of the opening in the middle is changed due to the movement of all the adjustment limiting plates 114, so that the passing flow is adjusted.
It should be noted that, when the valve core 104 rotates, in order to prevent the movement of the adjustment limiting plate 114, the fine adjustment input gear 219 rotates to drive the planet gear carrier 218 to rotate, the planet gear carrier 218 rotates to drive the planet gear 216 to rotate, and the planet gear 216 rotates to drive the outer ring gear 215 to rotate, because the sun gear 217 is connected with the output shaft of the fine adjustment motor 209, the rotation sun gear 217 needs to have a larger resistance, so that the outer ring gear 215 needs to be in an active state to release the torsion force, so that the adjustment limiting plate 114 is also in a moving state when the valve core 104 rotates, and when the valve core 104 moves, the fine adjustment motor 209 and the electromagnet 210 are in a power-off state, the electromagnet 210 attracts the limiting extrusion carrier 212, so that the outer ring gear 215 is in a freely rotatable state.
