一种防爆止水阀活动杆
By adding an explosion-proof water-stopping section and explosion-proof water-stopping components to the movable rod of the water-stopping valve, automatic water-stopping is achieved by utilizing the water pressure changes in the water flow channel. This solves the problem that the water-stopping valve cannot automatically stop water when the outer end of the water outlet bursts, simplifies the structure, and improves the water-stopping effect.

AI Technical Summary
The existing water stop valve has the problem of not being able to automatically shut off the water outlet in time when the water outlet valve is at the water pipe joint. In the event of a burst water outlet, the existing water stop valve cannot automatically stop the water outlet.
An explosion-proof water-stopping section is added to the movable rod of the water-stopping valve, and an explosion-proof water-stopping component is installed. Automatic water-stopping is achieved by utilizing the water pressure changes in the water flow channel. The component includes an inner baffle and an outer baffle. The explosion-proof water-stopping component seals the water flow channel through elastic and movable parts.
It achieves automatic water stop when the water outlet bursts, simplifies the structure, facilitates production and assembly, adapts to various water pipe joint structures, and improves the water-stopping effect.
