Abstract

The invention relates to a self-reset electric ball valve. The self-reset electric ball valve comprises an executor and a valve body assembly connected with the executor. The executor comprises an execution motor and a controller capable of controlling the execution motor to act. The self-reset electric ball valve further comprises a standby power supply arranged in the executor, and the controller controls the standby power supply to provide electricity for the execution motor when an external power supply is switched off. Since the standby power supply is arranged in the self-reset electric ball valve, one-to-one correspondence between the standby power supply and the self-reset electric ball valve is achieved; damage to the standby power supply in the self-reset electric ball valve cannot affect work of other self-reset electric ball valves, so that the influence range of the broken-down standby power supply is effectively narrowed. In addition, the standby power supply is arranged in the self-reset electric ball valve, any change of an external power supply circuit of the self-reset electric ball valve is not needed, and therefore the wiring difficulty is effectively reduced. The invention further discloses a control method of the self-reset electric ball valve.

Description

technical field [0001] The invention relates to the technical field of heating control, in particular to a self-resetting electric ball valve and a control method thereof applied in a heating process. Background technique [0002] In the process of heating and heating, it is necessary to use an on-off valve to control the on-off of heat. Electric ball valve is a kind of on-off valve commonly used in the current industry. [0003] Electric ball valves usually use a reversible synchronous hysteresis motor to drive the valve on and off. When the valve needs to be opened, the motor rotates clockwise or counterclockwise to drive the valve stem to open the valve; when the valve needs to be closed, the motor rotates in the opposite direction to drive the valve stem to close the valve. . However, in the heating process, there are often different requirements for normally open or normally closed for different requirements. Therefore, it must be considered that once the power supply ...
