Fire solenoid valve What does it do

< span style="font-size: 16px;">The solenoid valve is used in conjunction with the detector or controller. When the detector detects a fire alarm, it will output voltage to Solenoid Valve, thereby opening the solenoid valve to spray water. After the fire alarm is cleared, the solenoid valve automatically resets when it loses power, the valve closes, and the water source is cut off. . There is no water in the pipes (sprinkler branch pipes) of this system at ordinary times, and there is water in the pipes only under fire conditions. After knowing this principle, the solenoid valve cannot be dismantled.

The fire solenoid valve is a fire solenoid valve for the automatic tracking and positioning jet fire extinguishing system. It complies with the GB "Automatic Sprinkler System - General Valve" standard and has passed the type inspection of the "National Fixed Fire Extinguishing System and Fire-Resistant Components Quality Supervision and Inspection Center". The high-reliability solenoid valve adopts a piston-type pilot structure, an extra-large pilot hole, no scaling, no rust, fast opening and closing, and reliable performance, overcoming various shortcomings of existing solenoid valves. It is widely used in supporting products of sports venues, exhibition halls, industrial standard factories and various large space fire extinguishing systems.

Working principle of fire solenoid valve< /p>

Fire solenoid valve When the solenoid is energized, the moving iron core is attracted, driving the valve stem to move upward, and the spring is compressed at the same time, causing the valve stem to separate from the middle hole (pilot hole) of the valve core, and the fluid in the upper cavity of the valve core is instantly released from the middle hole. After pressure, the valve core floats upward quickly under the action of the pressure difference between the upper and lower chambers,The solenoid valve is opened. When the coil of the solenoid valve is powered off, the valve stem closes the middle hole of the valve core under the action of the spring force, and pushes the valve core downward to seal the fluid outlet, and the solenoid valve closes.
