The deluge valve, which is also called a flood valve, is a model of fire extinguisher valve that is used to shut off and connect the water flow in the fire extinguishing system. Dilag valve directs the flow of water to the nozzles in a very short time. In the deluge valve, the upstream water pressure keeps the valve locked and no additional force is needed to keep the valve open or locked. The water flow of the fire fighting network does this. For this reason, it is necessary to consider the water pressure to keep the deluge valve closed while designing the fire extinguishing system.
The fire extinguisher is one of the most widely used products in the field of firefighting, which is used as a basic tool for people who work in this field. This product is made of durable and high quality material so that it works well even in difficult and critical conditions. Due to its light weight and ease of transportation, the fire extinguisher is widely appreciated by people working in this field. Also, this product with special capabilities such as resistance to flames and creating a flow of water or extinguishing agents, becomes an essential and vital tool for every fire department. Therefore, the fire extinguisher is one of the products that increases safety and efficiency in the field of firefighting and is of special importance. Flood systems: These valves are most used in flood fire extinguishing systems, in situations where a large volume of water is needed quickly. This fire hydrant has a very fast operation so that the water is directed to the outlet nozzles in the shortest possible time. The flood valve is usually opened by an electric command.
This system is activated by a hydraulic-electrical or pneumatic actuator. Sprinklers in this system are open type. In fact, when there is a fire, they are all activated together. This system is used in dangerous places and places where fire can spread quickly. In critical situations and when we have a large fire, these valves provide the water needed by all sprinklers in the shortest time. This valve needs water with proper pressure upstream to close. To open the deluge valve, you can open the deluge valve by draining the water on the upper chamber. The flow of water entering the valve enters the valve chamber through the trim, then with the increase of the inlet water pressure and with the help of the spring, the upper and lower chambers of the valve are compressed to keep the water outlet closed. To open the valve dilation, it is enough to reduce the pressure on the chambers until the valve opens completely. Reducing the water pressure on the chamber is done by draining the water in them. To drain the water, you can also use the hand valve above the jamber. In automatic mode, by sending an electric signal to the solenoid valve, the water flow will exit the chamber. A pneumatic or hydraulic actuator can also be used to send the command to the solenoid valve.
