How to wire the fire solenoid valve, installation diagram of the fire solenoid valve

How to wire the fire solenoid valve? The fire solenoid valve requires a power cord and an alarm line and is connected to a single input single output module. Fire sprinkler preaction systems generally use solenoid valves. There are two installation locations for the solenoid valves. One is the solenoid valve of the alarm valve, and the other is located at the end of the main pipeline of the system partition. The red and yellow linkage wires are connected to the single input and output module, and then connected to the solenoid valve coil of the fire rapid exhaust valve group. The fire solenoid valve is a quick exhaust valve that cannot be automatically closed. The pipeline is usually full of gas. If the solenoid valve is not closed, the pre-action system cannot be maintained. Once the solenoid valve is opened when needed, the air will be directly discharged from the exhaust valve when the pipe network is opened. The system automatically switches to the wet state for fire extinguishing. If the solenoid valve is not installed, there is no way to manually open the exhaust. Fire solenoid valve installation diagram Automatic tracking and positioning jet fire extinguishing device (fire water monitor) is an efficient fire extinguishing product with large flow rate and long range. This fire monitor integrates computer technology, red-ultraviolet sensing technology, mechanical transmission technology and image transmission technology. It automatically detects the monitored range around the clock. Once a fire is discovered, it starts in time, completes the positioning within 60 seconds, and sends out a signal at the same time. The alarm signal is linked to electric valves, water pumps and other ancillary equipment to implement fixed-point water injection at the fire point to extinguish the fire. After the fire is extinguished, it will automatically stop and restart if there is a re-ignition. It can spray water in columnar or mist form, which greatly improves the fire extinguishing efficiency. The automatic tracking and positioning jet fire extinguishing device can be connected to the automatic fire alarm system, or can be combined with the fire extinguishing device on-site control box, the fire extinguishing device video centralized linkage control cabinet, etc. to form a centralized fire extinguishing management system. The fire pipeline system must carry out pipeline flushing and pipeline pressure testing. If it is not flushed, not only will the solenoid valve not close tightly, but debris will also block the nozzle of the water cannon, thereby affecting the range and flow rate of the water cannon. If the water monitor system and the sprinkler system share a pump room system, the water monitor main pipe must be connected in front of the wet alarm valve. If connected behind the wet alarm valve, the water monitor 5L-10L pipe network pressure can only reach 3-4 kg, and the nozzle cannot reach the rated pressure of 6 kg;the water monitor 20L-30L pipe network pressure can only reach 5-6 kg. The nozzle does not reach the rated pressure of 8 kg. If a DN50 filter is not installed between the gate valve and the solenoid valve, impurities in the pipeline will cause the solenoid valve to not close tightly, resulting in long-term water leakage. This will make subsequent maintenance very difficult. The distance between the solenoid valve and the fire water monitor should be as short as possible, but the length between the solenoid valve and the fire water monitor should not be less than 10CM. If it is too long, it will affect the effect of the water cannon. The distance between the electric valve and the water monitor flange. The distance between the electric valve and the water monitor flange should be no less than 15 centimeters. If the installation distance is too close, when the electric valve rotates, the baffle will be stuck by the flange, resulting in lax closing, burnout of the electric valve, and insufficient water injection flow. Precautions for installation of fire solenoid valves Wiring: Do not connect strong electricity to the CAN and RS485 communication ports. The shielding layer of the communication line must be grounded. The communication line should be passed through the pipe separately and transported separately from the strong electricity: the water monitor should not be violently shaken. Handle it gently to minimize the vibration of the gun body. Installation site: The installation site should be away from sunlight, ultraviolet light, high-power equipment, high-temperature equipment, lifting equipment and other sites with magnetic field interference, light interference, high-temperature interference and other environmental interference. Installation: Pay attention to the bottom of the cannon when installing. Do not smash the UV tube, and check whether there is any dirt residue on the UV tube. It is best to place the water monitor flat. Do not place the sensor directly on the table or the ground without any protective measures.
