AI Technical Summary
When a liquid storage tank explodes, the pressure inside the tank rises rapidly, which can easily damage both the radar level gauge and the storage tank.
An explosion-proof radar liquid level detection device was designed, including a liquid level gauge body and an explosion-proof protection mechanism. It is equipped with an anti-collision tank, an exhaust pipe and a fixing component. The exhaust pipe is connected inside and outside the liquid storage tank. Under normal circumstances, it is closed. In the event of an explosion, it automatically releases pressure to prevent the high pressure inside the liquid storage tank from damaging the liquid level gauge.
It effectively prevents the level gauge from being damaged by collision and explosion pressure, avoids the substances in the storage tank from being affected by electric current or flammable vapor, eliminates the possibility of explosion, and protects the safety of the level gauge and storage tank.
