In the process of lifting the piston 260, the guide block 261 of the first piston 260 and the guide block 261 of the second piston 260 are both in the second thread groove 252 under normal conditions, and the total water yield is the sum of V1 and V2, in the process of reversing the piston 260, when the guide block 261 of the first piston 260 enters a reversing area from the second thread groove 252, the amount of the pressurized water is gradually reduced, meanwhile, the guide block 261 of the second piston 260 enters the first thread groove 251 from the second thread groove 252, and the lifting distance in a fixed interval is gradually increased to compensate for the reduced pressurized water yield when the first piston 260 reverses, and the total water yield is unchanged; when the guide block 261 of the second piston 260 enters the reversing area from the first thread groove 251, the amount of pressurized water is gradually reduced, the guide block 261 of the first piston 260 enters the first thread groove 251 from the reversing area, and the ascending distance in the fixed interval is gradually increased to compensate for the reduced amount of pressurized water when the second piston 260 reverses; when the reversing of the second piston 260 is finished, the guide block 261 of the second piston 260 enters the second threaded groove 252, and the guide block 261 of the first piston 260 enters the second threaded groove 252 from the first threaded groove 251, wherein the total water yield is the sum of V1 and V2.
In the descending process of the piston 260, the guide block 261 of the first piston 260 and the guide block 261 of the second piston 260 are both in the second thread groove 252 under normal conditions, and the total water yield is the sum of V1 and V2 at this time; when the guide block 261 of the second piston 260 enters the reversing area from the first thread groove 251, the amount of pressurized water is gradually reduced, the guide block 261 of the first piston 260 enters the first thread groove 251 from the reversing area, and the ascending distance in the fixed interval is gradually increased to compensate for the reduced pressurized water amount when the second piston 260 reverses; when the reversing of the second piston 260 is finished, the guide block 261 of the second piston 260 enters the second thread groove 252, and the guide block 261 of the first piston 260 enters the second thread groove 252 from the first thread groove 251, and the total water yield is the sum of V1 and V2.
This allows the amount of water exiting the regulator valve to be a constant value throughout the constant rotation of the hand wheel 110.
