CA-FIRE Deluge Valve Manufacturers
1.Standard and Certification
Deluge Valve Manufacturers complies with the core requirements of GB 5135.5-2019 "Automatic Sprinkler Systems - Part 5: Deluge Valve Alarm System", is compatible with GB 50084 "Design Code for Automatic Sprinkler Systems" and GB 50261 "Construction and Acceptance Code for Automatic Sprinkler Systems", has passed CCCF compulsory certification, and can be optionally equipped with UL/FM international certifications.
2. Core Positioning and Applicable Scenarios
Function Positioning: As the control core of the open fire suppression system, it is driven by pressure difference to quickly open, enabling instantaneous water filling of the pipeline network and simultaneous alarm. It is suitable for places where fire spread is rapid and full-immersion fire suppression is required. Typical Scenarios: Petrochemical storage areas, cable tunnels, transformer rooms, large warehouses, theater stages, etc., in severely hazardous protection zones. It can be adapted to water spray, water curtain, and foam-water combined systems.
Working Principle
1. Standby state
The water supply side and the control chamber maintain pressure balance through the throttle orifice plate. The QT450 valve disc is tightly pressed against the valve seat under the pressure of the control chamber, and the system side pipe network is in an empty pipe state; the alarm pipeline is stationary without water flow, so the water pressure alarm bell and pressure switch do not operate.
2. Startup and operation process
Trigger signal: The fire automatic alarm system triggers the electromagnetic valve to release pressure, or the transmission pipe sprinkler bursts to release pressure, or the emergency ball valve is manually opened.
Pressure difference formation: The pressure in the control chamber rapidly decreases, and the pressure difference between the water supply side and the control chamber exceeds the 2:1 threshold, pushing the valve disc to open instantly (opening time ≤ 1 second).
Extinguishing and alarm: Water from the water supply side flows into the system side pipe network and forms a submerged spray through open sprinklers; at the same time, some water flows into the alarm pipeline, driving the water pressure alarm bell to ring (≥ 85 dB), and the pressure switch sends a signal to the fire control center to联动start the fire pump.
Locking protection： After the valve disc is opened, the anti-reset mechanism automatically clamps, preventing the valve disc from closing due to water pressure fluctuations.
Test Acceptance
Test Acceptance
Pressure Test: Close the valve on the system side, slowly increase the pressure to 1.76 MPa (1.1 times the working pressure), maintain the pressure for 30 minutes without leakage.
Function Test: Power on and trigger the electromagnetic valve, check the flexibility of the valve disc opening, and the timeliness of the alarm signal response (≤ 3 seconds); Test the manual emergency device to ensure there is no jamming.
Our Advantages
Reliable Performance: Made from high-quality materials such as carbon steel or stainless steel, ensuring long-term durability and corrosion resistance under high-pressure conditions.
Clear Position Indication: The rising stem design provides a visible indication of the valve's open or closed status, reducing operational errors.
Remote Monitoring Capability: Integrated signal device allows real-time status transmission to control panels or automation systems, enhancing safety and operational efficiency.
Versatile Applications: Suitable for fire protection, water supply, HVAC, and industrial piping systems.
Easy Maintenance & Installation: Flanged connections simplify installation and maintenance, minimizing downtime.
Safety & Compliance: Designed to meet international standards and regulatory requirements, ensuring secure and compliant operation.
