    What kind of valve will be?used in the fire water system

    Posted by Bundor valve
    What kind of valve will be used in the fire water system? Common valves for fire water systems include resilient seat gate valves, signal butterfly valves, signal gate valves, check valves, ball valves, solenoid valves and globe valves. Each valve has different function in the fire water system. Bundor will introduce to you one by one.

    Resilient seat gate valve
    Resilient seat gate valve is the most commonly used valve in water system, its sealing performance is very good, mainly used to cut off the water flow in the pipeline. In the fire water system pipeline, resilient seat gate valve is an essential valve.
    Signal butterfly valve
    Signal butterfly valve is an ordinary butterfly valve with a set of signal lines added and connected to the fire alarm host together with the monitoring module. The signal (input module) module indicator light is always shine when the valve is closed, the module signal indicator light is shine when the valve is normally open. The signal butterfly valve in fire protection is the switch in the fire protection pipeline network, because the water in the fire protection pipeline network must be kept unblocked, so as to ensure the timeliness of fire fighting, so once the signal butterfly valve is closed, the signal module will report feedback information to the host and notify the monitoring center. The fire network is closed. The opening and closing of normal butterfly valves cannot be seen through the alarm host, only be viewed on site.
    Signal gate valve
    The principle is the same as that of the signal butterfly valve.
    check valve
    Check valve only allows the flow of the medium in one direction and prevents flow in the opposite direction. Usually this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve flap opens, when the fluid flows in the opposite direction, the fluid pressure and the self-coincident valve flap of the valve flap act on the valve seat, thereby cutting off the flow. Installed on the fire water system pipeline to prevent backflow of water and ensure the safety of pipeline equipment.
    Ball valve
    Ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the water in the pipeline. It only needs to be rotated 90 degrees and a small torque can be closed tightly. Ball valves are most suitable for switching and shut-off valves.
    The electromagnetic valve
    Solenoid valve is an automatic basic component used to control fluids. It belongs to the actuator and is not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium.
    Shut-off valve
    The globe valve is used to cut off the flow of the medium. Globe valve is suitable for occasions that need to be opened frequently.  Globe valve can be used for pipelines such as water, steam and compressed air, but it is not suitable for medium pipelines with high viscosity, coking and sedimentation, so as not to damage the sealing surface.
