Deluge Alarm Valve

It's fundamentally different from the common "wet alarm valve." While conventional sprinkler systems have each nozzle independently respond to temperature and burst water, a deluge system simultaneously distributes water across the entire protected area. Once a Deluge Alarm Valve is activated, all its outlets instantly open, flooding the entire pipe network with water, resembling a torrential downpour. Hence the name "deluge."Fuxeon® can provide customers with free samples. Please send an inquiry.

Advantages

After prolonged use, Deluge Alarm Valve on the market are prone to internal rusting. In contrast, we employ a unique electric arc copper spraying process, which offers greater wear and corrosion resistance, resulting in a longer service life.

Function and application description

The ZSFM deluge alarm valve offers two main configurations depending on the installation configuration: one is an open sprinkler system installed on a sprinkler network. Normally, the network is dry, and a diaphragm isolates the water supply. In the event of a fire, the diaphragm opens, causing all open sprinklers to spray water simultaneously. This design is suitable for locations such as flammable and explosive warehouses. The other is a closed sprinkler system. Normally, the network is filled with water, and in the event of a fire, the diaphragm opens, allowing all closed sprinklers to spray water simultaneously.

This system can also be divided into two types: wet and electronic, depending on the detection and control device. The wet system uses closed sprinklers to detect a fire. Upon rupture, the network pressure drops, causing the diaphragm to open, resulting in localized water spraying. This system requires a manual valve or diaphragm chamber connection. The electronic system uses an electronic detector to trigger a solenoid valve to release diaphragm pressure. This system can be flexibly designed as an open network for full-area water spraying or a closed network for localized water spraying. It supports both dry and wet control modes to adapt to different environmental requirements.

FAQ

Q1: What are the main application scenarios of deluge alarm valve?

Deluge alarm valve is the core control equipment of deluge fire sprinkler systems. It is widely used in high-risk fire areas such as chemical plants, oil & gas stations, power plants, industrial tunnels, aircraft hangars and flammable material warehouses. It supports full-area simultaneous water spray for rapid cooling and fire containment.

Q2: What key materials are used for deluge alarm valve?

The main valve body is made of heavy-duty ductile iron or cast brass with anti-corrosion painting. Internal diaphragms, seal rings and gaskets adopt heat-resistant and aging-resistant rubber materials. Guide parts, fasteners and thread components use stainless steel to ensure high pressure resistance, wear resistance and long-term outdoor & industrial durability.

Q3: What is the working principle advantage of deluge alarm valve?

Different from ordinary wet alarm valves, the deluge valve keeps the system pipeline empty under normal status. Once triggered by fire detection, solenoid valve or manual control, the valve opens instantly. All open deluge sprinklers spray water at the same time to suppress large-area spreading fires in the shortest time.
