[0023] like Figure 4-6 As shown, this example can achieve the effect of stably and precisely driving the valve plate 201 to rotate.

[0024] The intelligent electric valve includes a housing 101, within which a valve plate 201 is disposed. A vertical shaft 202 is welded onto the valve plate 201. The upper part of the vertical shaft 202 passes through the housing 101 and is rotatably connected to the housing 101. A worm gear 207 is connected to the upper end of the vertical shaft 202. Driving the worm gear 207 to rotate can stably and precisely drive the valve plate 201 to rotate.

[0025] like Figure 4-6 As shown, this example can achieve the effect of precisely driving the vertical shaft 202 and the valve plate 201 to rotate.

[0026] Since support rods 107 are welded to both the front and rear ends of the upper side of the housing 101, the front and rear ends of the worm 104 are rotatably connected to the two support rods 107 respectively. Limiting rings 105 are welded to both the front and rear ends of the worm 104. The two limiting rings 105 are located on the outside of the two support rods 107 respectively. The worm 104 meshes with the worm wheel 207 for transmission. The worm 104 can rotate between the two support rods 107 around its own axis, thereby driving the worm wheel 207 to rotate. Through the cooperation between the worm 104 and the worm wheel 207, the worm wheel 207 is precisely driven to rotate, thereby precisely driving the vertical shaft 202 and the valve plate 201 to rotate.

[0027] like Figure 4-10 As shown, this example can achieve the effect of precisely driving the worm gear 104 to rotate via the intelligent motor 505.

[0028] Since the front part of the worm gear 104 is provided with a hexagonal slot 106, a hexagonal prism 503 is connected to the output shaft of the intelligent motor 505 by screws. The hexagonal prism 503 can be inserted into the hexagonal slot 106. The speed and amount of rotation of the intelligent motor 505 can be precisely controlled, thereby inserting the hexagonal prism 503 into the hexagonal slot 106 and precisely driving the worm gear 104 to rotate through the intelligent motor 505.

[0029] like Figure 9-10 As shown, this example can achieve the effect of controlling the connection and disconnection of the hexagonal prism 503 and the hexagonal slot 106.

[0030] Because the front side of the housing 101 is connected to an L-shaped frame 501 by screws, a track rod 508 is welded on the L-shaped frame 501, and a motor base 506 is slidably connected to the track rod 508. The intelligent motor 505 is connected to the motor base 506 by screws, and the motor base 506 can slide on the track rod 508, thereby driving the intelligent motor 505 and the hexagonal prism 503 to move back and forth, thereby controlling the connection and disconnection of the hexagonal prism 503 from the hexagonal slot 106.

[0031] like Figure 9-10 As shown, this example can achieve the effect of conveniently connecting the hexagonal prism 503 and the hexagonal slot 106.

[0032] Because the front end of the track rod 508 is connected to the disc 507 by screws, and a compression spring is sleeved on the track rod 508, the compression spring is located between the motor base 506 and the disc 507. The compression spring exerts a force on the motor base 506 to slide backward, so that the intelligent motor 505 always tends to move backward, and the hexagonal prism 503 always tends to insert into the hexagonal slot 106, which facilitates the connection between the hexagonal prism 503 and the hexagonal slot 106.

[0033] like Figure 9-10 As shown, this example can prevent others from inserting a wrench into the hexagonal slot 106 and arbitrarily turning the valve.

[0034] Because a stop bar 502 is vertically slidably connected to the L-shaped frame 501, the stop bar 502 can block the front side of the hexagonal slot 106. The two ends of the diagonal bar 504 are respectively hinged to the lower end of the stop bar 502 and the motor base 506. The front side of the L-shaped frame 501 is connected to an electric telescopic rod 509 by screws. The movable end of the electric telescopic rod 509 presses against the rear side of the motor base 506. When the electric telescopic rod 509 extends, it drives the motor base 506 to slide forward, thereby driving the hexagonal prism 503 to disengage from the hexagonal slot 106, so that the motor base 506 slides forward and drives the stop bar 502 to slide upward through the diagonal bar 504, thereby driving the stop bar 502 to the front side of the hexagonal slot 106, preventing others from inserting a wrench into the hexagonal slot 106 and arbitrarily operating the valve.

[0035] like Figure 4-6 As shown, this example can achieve the effect of controlling the maximum rotation angle of the worm gear 207 and the valve plate 201.

[0036] Since the upper end of the worm gear 207 is welded with a threaded post 206, the connecting piece 205 is inserted into the threaded post 206, and a nut is threaded onto the threaded post 206. The nut presses on the connecting piece 205. The end of the connecting piece 205 is connected to a hollow sleeve 203 by a screw. Both ends of the hollow sleeve 203 are slidably connected to sliding pillars 204. Both ends of the hollow sleeve 203 are threadedly connected to fastening screws. The two fastening screws press on the two sliding pillars 204 respectively. The length of the sliding pillars 204 protruding from the hollow sleeve 203 can be manually adjusted. When the worm gear 207 rotates a certain angle, the sliding pillars 204 will contact the worm 104. At this time, the rotation of the worm 104 is restricted, thereby controlling the maximum rotation angle of the worm gear 207 and the valve plate 201. It can also control the valve plate 201 to not continue to rotate after it is closed, preventing the valve plate 201 from rotating excessively.

[0037] like Figure 4-6 As shown, this example can achieve the effect of pressing the two side tubes 301 against both sides of the housing 101.

[0038] Since both sides of the housing 101 are welded with annular edges 102, and each annular edge 102 is fitted with a side tube 301, and each side tube 301 is welded with a protruding plate 304, the two ends of the screw 303 pass through the two protruding plates 304 respectively, and both ends of the screw 303 are threaded with nuts. By rotating the nuts at both ends of the screw 303, the two side tubes 301 tend to move closer to each other, thereby pressing the two side tubes 301 against both sides of the housing 101, thus completing the connection of the two side tubes 301.

[0039] like Figure 7-8As shown, this example can achieve the effect of installing the support ring 410 at different positions inside the side tube 301.

[0040] Because multiple slots 302 are provided on both the front and rear sides of the side tube 301 from left to right, the support ring 410 is inserted into the side tube 301. Elastic rods 409 are welded to both the front and rear sides of the support ring 410, and a locking block 408 is welded to the end of each elastic rod 409. Two locking blocks 408 are respectively inserted into the slots 302 on both sides. A pull ring 405 is provided on the inner side of the elastic rod 409. By locking the two locking blocks 408 into different slots 302, the support ring 410 is installed in different positions within the side tube 301. The pull ring 405 on the inner side of the elastic rod 409 facilitates pulling the elastic rod 409 outwards to elastically bend it, allowing the locking block 408 to be removed from the slot 302.

[0041] Each of the card blocks 408 is welded with a threaded post 407, and the two ends of the positioning rod 406 are respectively inserted into the two threaded posts 407. Each threaded post 407 is threaded with a nut.

[0042] like Figure 7-8 As shown, this example can prevent two card blocks 408 from leaving their corresponding card slots 302.

[0043] After the two locking blocks 408 are engaged in the slots 302, the positioning rod 406 is inserted into the two threaded post 407 to prevent the two locking blocks 408 from leaving the corresponding slots 302.

[0044] The upper and lower ends of the support ring 410 are slidably connected to guide rods 403 in the left and right directions. Each guide rod 403 has a stop 404 fixed at its left end. A ring 402 is fixed between the right ends of the two guide rods 403. Each guide rod 403 is fitted with a compression spring, which is located between the ring 402 and the support ring 410. A rubber ring 401 is glued to the right side of the ring 402 and presses against the outer ring of the valve plate 201.

[0045] like Figure 4-10 As shown, this example can further improve the sealing performance of valve plate 201 when valve plate 201 is closed.

[0046] The compression springs on the two guide rods 403 apply pressure to the ring 402 and the rubber ring 401, causing the ring 402 and the rubber ring 401 to press against the outer ring of the valve plate 201. When the valve plate 201 is closed, the sealing performance of the valve plate 201 is further improved. When the valve plate 201 rotates, it drives the ring 402 and the rubber ring 401 to move outward. At this time, the two guide rods 403 slide outward on the bracket ring 410. Adjusting the bracket ring 410 at different positions can adjust the compression degree of the compression springs on the two guide rods 403, thereby adjusting the pressure of the ring 402 and the rubber ring 401 on the valve plate 201.
