AI Technical Summary
The existing ball valve switch cannot effectively remind staff to close it in time when it is open at different degrees, which poses a safety hazard.
Design an alarm device to be installed on a ball valve switch. The device uses a magnet and a metal plate to switch the valve on and off, and uses a buzzer to sound an alarm. The position of the alarm mechanism is adjusted according to the valve opening to ensure that staff are alerted at different opening degrees.
This provides effective warnings at different opening degrees of the ball valve, preventing workers from forgetting to close the ball valve and improving production safety.
