Rain alarm valve
Product Introduction
◆ The deluge alarm valve has a control chamber, a water supply chamber, and a system chamber.
The deluge alarm valve opens or closes by controlling the pressure in the control chamber by pressurizing and depressurizing the diaphragm to seal the water supply chamber. The alarm valve can be activated by a solenoid valve or by opening the emergency start ball valve. The anti-reset valve seals the water inlet of the control chamber when the deluge alarm valve opens due to pressure relief, preventing the valve from resetting and cutting off water supply when pressurization is needed. It also opens the water inlet to replenish pressure and reset the diaphragm when the deluge alarm valve needs to close. This prevents accidental spraying due to water pressure fluctuations when the deluge alarm valve is in standby mode.
Features
◆ ZSFM produced by our company The series of diaphragm-type deluge alarm valve skid systems are technologically mature, with stable performance, sensitive operation, and the following characteristics: ◆ 1.1. Unobstructed valve port and full-bore valve body, resulting in high reliability and fire extinguishing efficiency. ◆ 1.2. Online maintenance is possible, reducing system downtime. ◆ 1.3. Prevents automatic valve disc reset, ensuring reliable operation. ◆ 1.4. Supports multiple control methods for starting, including electric, hydraulic, pneumatic, and mechanical. ◆ 1.5. The integrated molded elastic diaphragm assembly is the only moving part, requiring no maintenance. ◆ 1.6. The deluge valve can complete the entire process from start-up to nozzle water output within 60 seconds, with no mechanical rotating parts, avoiding the risk of jamming.
