AI Technical Summary
The existing ball valves lack high-pressure early warning components, making it impossible to observe the internal pressure in a timely manner, which affects the safety of use.
An alarm device is installed inside the ball valve, including components such as a circular groove, telescopic rod, ball catcher, connecting column, and alarm light. When the pressure is too high, the connecting column is fixed to the connecting stake, and the alarm light illuminates and sounds an alarm. After the pressure returns to normal, the valve resets and cuts off the power to prevent the connecting column from being impacted and bent.
It enables timely alarms under high pressure to prevent damage to the connecting column, ensure the safe use of the ball valve, and avoid rigid contact during connection to improve ease of operation.
