Product description

The deluge alarm valve (flange) consists of deluge valve, hydraulic alarm bell, anti-reset valve, solenoid valve and control chamber water supply pipeline, deluge alarm valve opening pipeline, alarm pipeline, drain pipeline, pressure gauge and other components composition. In automatic sprinkler systems, deluge valves are widely used, and are widely used in open systems such as rain shower systems, water curtain systems, and water spray fire extinguishing systems. It can also be used in closed systems, such as pre-action systems.

Features

The valve has a control cavity, a water supply cavity and a system cavity. Relying on the diaphragm to seal the pressure water in the water supply chamber, the pressure and relief of the chamber are controlled to change the position of the diaphragm, thereby opening or closing the deluge alarm valve. The solenoid valve can be activated or the emergency start ball valve can be opened to activate the alarm valve. The function of the anti-reset valve is to seal the water inlet channel of the control chamber after the pressure relief deluge alarm valve of the control chamber is opened, to prevent the control chamber pressurization deluge alarm valve from resetting and cutting off water. When the deluge alarm valve needs to be closed, open the control chamber The water inlet channel is pressurized to reset the diaphragm. Prevent the accidental spray accident caused by the water pressure fluctuation when the rain alarm valve is in the servo state.
