[0014] The present invention also provides another technical solution: a maintenance method for an electric regulating valve, comprising the following steps:

[0015] S1. When installing the valve body, after aligning the two ends of the valve body with the pipeline, place the end of the connecting fixing bolt into the disassembly seat, and then rotate the turntable to drive the first worm to rotate through the turntable. When the first worm rotates, it drives the first worm wheel to rotate. At this time, the driving gear is driven to rotate through the intermediate shaft. When the driving gear rotates, it drives the movable gear ring to rotate. When the movable gear ring rotates, the outer screw sleeve is driven to rotate through the fixed gear ring. Since the limit rod is inserted into the limit groove, the disassembly screw cannot rotate. When the outer screw sleeve rotates, it drives the disassembly screw to move away from the fixing ring. At this time, the fixing bolt is pushed into the installation hole by the disassembly screw, so that the valve body is fixed. When the valve body needs to be maintained, it only needs to rotate the turntable in the opposite direction, so that the disassembly screw drives several fixing bolts to move out of the installation hole at the same time, so as to remove the valve body for maintenance;

[0016] S2. When the valve body is in normal use, the filter frame filters the liquid entering the valve body to prevent impurities in the pipeline from entering the valve body and causing blockage and damage to the valve body. During use, the water flow entering the valve body drives the turbofan to rotate, which in turn drives the transmission rod to rotate, and the transmission rod drives the rotating rod to rotate. The rotating rod scrapes the filter surface of the filter frame, so that the filter frame can maintain high-efficiency filtering capabilities for a long time;

[0017] S3. When the turntable is reversed to remove the valve body for maintenance and repair, the turntable drives the first worm to rotate, so that the second worm follows the first worm, and then the second worm drives the second worm wheel to rotate, so that the inner thread sleeve follows the second worm wheel. When the inner thread sleeve rotates, it drives the translation screw to move away from the support frame, so that the filter frame follows the translation screw to move, and the accumulated impurities are pushed out of the valve body through the filter frame, so that when the valve body is removed, the impurities blocked by the filter frame are pushed out at the same time, which is convenient for cleaning and maintenance.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention is designed to install a disassembly and assembly mechanism. When installing the valve body, it is only necessary to rotate the turntable to drive the movable gear ring to rotate. When the movable gear ring rotates, it simultaneously drives a plurality of disassembly and assembly screws to move away from the fixed ring, so as to push the fixing bolt into the installation hole, so that the valve body can be quickly installed and fixed. When the valve body needs to be maintained and repaired, it is only necessary to reverse the turntable to quickly remove the valve body, so that the maintenance personnel do not need to operate each fastener when installing or removing the valve body, thereby speeding up the disassembly and assembly of the valve body and improving the maintenance efficiency of the valve body.

[0020] 2. The present invention is designed and installed with a discharge mechanism, in which the water flow entering the valve body drives the turbofan to rotate, and then drives the rotating rod to rotate through the transmission rod, and the filtering surface of the filter frame is scraped by the rotating rod, so that the filter frame can maintain high-efficiency filtering ability for a long time. When the valve body is removed for maintenance and repair, the inner screw sleeve is driven to rotate by the turntable, so that the filter frame moves with the translation screw, and the accumulated impurities are pushed out of the valve body through the filter frame, so that when the valve body is removed, the impurities blocked by the filter frame are pushed out at the same time, which is convenient for cleaning and maintenance.

[0037] The present invention also provides another technical solution: a maintenance method for an electric regulating valve, comprising the following steps:

[0038] S1. When installing the valve body 1, align the two ends of the valve body 1 with the pipeline, place the end of the connecting fixing bolt into the disassembly seat 206, and then rotate the turntable 213 to drive the first worm 212 to rotate through the turntable 213.

When the driving gear 210 rotates, it drives the movable gear ring 204 to rotate. When the movable gear ring 204 rotates, the outer screw sleeve is driven through the fixed gear ring 203. 202 rotates, and since the limiting rod 208 is inserted into the limiting groove 207, the disassembly screw 205 cannot rotate. When the outer screw sleeve 202 rotates, the disassembly screw 205 is driven to move away from the fixing ring 201. At this time, the disassembly screw 205 pushes the fixing bolt to move into the mounting hole, so that the valve body 1 is fixed. When the valve body 1 needs to be maintained, it is only necessary to rotate the turntable 213 in the opposite direction, so that the disassembly screw 205 drives several fixing bolts to move out of the mounting hole at the same time, so that the valve body 1 can be removed for maintenance.

[0039] S2. When the valve body 1 is in normal use, the filter frame 306 filters the liquid entering the valve body 1 to prevent impurities in the pipeline from entering the valve body 1 and causing blockage and damage in the valve body 1. During use, the water flow entering the valve body 1 drives the turbofan 310 to rotate, and the turbofan 310 drives the transmission rod 309 to rotate, and the transmission rod 309 drives the rotating rod 311 to rotate, and the rotating rod 311 scrapes the filtering surface of the filter frame 306, so that the filter frame 306 can maintain high-efficiency filtering ability for a long time;

[0040] S3. When the turntable 213 is reversed to remove the valve body 1 for maintenance and repair, the turntable 213 drives the first worm 212 to rotate, so that the second worm 304 rotates following the first worm 212, and then the second worm 304 drives the second worm wheel 303 to rotate, so that the inner screw sleeve 302 rotates following the second worm wheel 303. When the inner screw sleeve 302 rotates, it drives the translation screw 305 to move away from the support frame 301, so that the filter frame 306 moves following the translation screw 305, and the accumulated impurities are pushed out of the valve body 1 through the filter frame 306, so that when the valve body 1 is removed, the impurities blocked by the filter frame 306 inside are also pushed out, which is convenient for cleaning and maintenance.

The end of the transmission rod (309) away from the middle of the valve body (1) is installed in the middle of the filter frame (306) by inserting. The turbofan (310) is fixedly installed at the end of the transmission rod (309) away from the filter frame (306) by bolts, and is also installed at the end of the translation screw (305) away from the filter frame (306) by bearings. The end of the rotating rod (311) located in the middle of the filter frame (306) is fixedly connected to the transmission rod (309) by bolts.

8. A maintenance method for an electric regulating valve, applicable to the easy-to-maintain electric regulating valve according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1. When installing the valve body (1), align the two ends of the valve body (1) with the pipeline, place the end of the connecting fixing bolt into the disassembly seat (206), and then rotate the turntable (213). The turntable (213) drives the first worm (212) to rotate. When the first worm (212) rotates, it drives the first worm wheel (211) to rotate. At this time, the driving gear (210) is driven to rotate through the intermediate shaft (209). When the driving gear (210) rotates, it drives the movable gear ring (204) to rotate. When the movable gear ring (204) rotates, the fixed gear ring (203) drives the external screw When the sleeve (202) rotates, the limiting rod (208) is inserted into the limiting groove (207), so that the disassembly screw (205) cannot rotate. When the outer screw sleeve (202) rotates, the disassembly screw (205) is driven to move in a direction away from the fixing ring (201). At this time, the disassembly screw (205) pushes the fixing bolt to move into the installation hole, so that the valve body (1) is fixed. When the valve body (1) needs to be maintained, it is only necessary to rotate the turntable (213) in the opposite direction, so that the disassembly screw (205) drives the plurality of fixing bolts to move out of the installation hole at the same time, so that the valve body (1) can be removed for maintenance. S2. When the valve body (1) is in normal use, the filter frame (306) filters the liquid entering the valve body (1) to prevent impurities in the pipeline from entering the valve body (1) and causing blockage and damage to the valve body (1). During use, the water flow entering the valve body (1) drives the turbofan (310) to rotate, and the turbofan (310) drives the transmission rod (309) to rotate, and the transmission rod (309) drives the rotating rod (311) to rotate, and the rotating rod (311) scrapes the filtering surface of the filter frame (306), so that the filter frame (306) can maintain high-efficiency filtering capabilities for a long time. S3. When the turntable (213) is reversed to remove the valve body (1) for maintenance and repair, the turntable (213) drives the first worm (212) to rotate, so that the second worm (304) rotates following the first worm (212), and then the second worm (304) drives the second worm wheel (303) to rotate, so that the inner thread sleeve (302) rotates following the second worm wheel (303). When the inner thread sleeve (302) rotates, it drives the translation screw (305) to move away from the support frame (301), so that the filter frame (306) moves following the translation screw (305), and the accumulated impurities are pushed out of the valve body (1) through the filter frame (306), so that when the valve body (1) is removed, the impurities blocked by the filter frame (306) inside are also pushed out, so as to facilitate cleaning and maintenance.
