Problems solved by technology

If there is no flood or power failure for a long time, after the ball valve does not rotate for a long time, once flood or power failure occurs, the initial rotational torque of the ball valve will be very large, which will cause the internal driver to fail to drive the ball valve, and the ball valve will not close. ; Even if the ball valve is damaged during use, it cannot be found in time, resulting in flooding or failure to use normally when the power is cut off

Abstract

The invention discloses a water leakage protection device for an electric ball valve, which includes a control circuit, a ball valve rotation self-inspection mechanism, an alarm circuit and a power circuit for supplying power to the whole device. The control circuit regularly controls the motor drive circuit to drive the motor to rotate forward or reverse Reset, the ball valve rotation self-inspection mechanism is used to detect whether the ball valve rotates normally, and feeds back the detected signal to the control circuit, the alarm circuit is connected to the control circuit, and the control circuit judges whether the alarm circuit is passed according to the signal fed back by the ball valve rotation self-inspection mechanism Alarm; the advantage is that the ball valve rotation self-inspection mechanism can be added to regularly monitor whether the ball valve is working normally. Once there is a problem, the user can be reminded to repair it in time to ensure that the ball valve does not suffer from flooding for a long time. The motor can normally and quickly drive the ball valve to close; to ensure that the ball valve can be closed normally when flooding or power failure occurs.

Description

technical field [0001] The invention relates to the technical field of electric ball valves, in particular to a water leakage protection device for electric ball valves. Background technique [0002] Electric ball valve is an important actuator in industrial automation control system. It is widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and occupies a pivotal position in the national economy. The electric ball valve is equipped with a water leakage protection actuator. When there is a flood and the power is cut off, the water leakage protection actuator drives the ball valve to close the water source. If there is no flood or power failure for a long time, after the ball valve does not rotate for a long time, once flood or power failure occurs, the initial rotational torque of the ball valve will be very large, which will cause the internal dr...
