AI Technical Summary
The existing electric valves of the fire water supply pipes cannot be opened normally when there is a power outage or power failure, resulting in the inability to deliver fire-fighting water and delaying rescue.
An electric valve device for fire water supply pipes, combining electric and manual operation, was designed. By setting a sealing rod and bolt structure, the valve can be manually opened in the event of a power outage, ensuring the normal supply of fire-fighting water.
In the event of a power outage, firefighters can quickly open valves manually to ensure the normal supply of water for firefighting and avoid affecting rescue efforts due to power failure.
