High-rise building fire hydrant valve control valve of the signal

In accordance with the "Code for Fire Protection Design of Tall Buildings" provisions in the indoor fire hydrant system, water supply pipeline valve applications divided into a number of independent paragraph, and the gate valve should be clearly marked. This is in order to repair the pipes to stop using the number of not less than one fire hydrant risers.



With the development of modern architecture, building aesthetic requirements for the various channels should be concealed as far as possible arrangements, therefore, fire hydrant located in the ceiling inside the pipe, tube wells, is widespread, but there is a problem, that is, pipeline fire hydrant control valves are not open to monitor for fire hydrant use can cause problems. For example as follows:



"Ministry of Electric Power Control Center of State Grid" project for the construction area of 50,000 square meters, floor, 27 on the ground floor, building more than one hundred and ten meters high, command scheduling for production, office meetings and other functions into one integrated of intelligent building, and its high degree of automation is rare in China. His automatic spray liquor in the design of the system, I will all the water valves before indicator signal valves are used, so the state system of fire control center can be displayed, and can identify problems at a glance, while living and Fire water level control, fire pump start and stop and so on have been a reasonable control, with the exception of fire hydrant valve control system only in accordance with the norms of the ordinary valve, it has obvious signs of the headstock, but not in the fire control center to show that the other needs of these valves are located for the beautiful in the tube and the ceiling, the current quality of workers also can not guarantee the reliability of the system. Therefore, in its fire-fighting system in the acceptance process, even though the leadership of the Ministry of Electric Power Engineering Command, construction units and design units have attached great importance to early to do the deployment and improvement, Wells had a preview, but the actual fire official acceptance process, but there are problems, there is a fire hydrant on a fire hydrant risers put no water in any case, while the other four are normal water, the fire control center is able to detect the problem. Found later in this root tube closed at both ends because the maintenance of control valves, and repair workers are not finished to open the valve, resulting in no water hydrant.



We all attach great importance in the circumstances, this problem is still there, and usually easily negligent in the circumstances there will be more difficult to know what kind of problem. This is related to the fire hydrant system when the possibility of rational use of the key issues, and avoid this from happening the most reliable approach is to control valves, fire hydrant systems are equipped with valve into the signal and open the valve in the fire control center to manage testing, although the cost has increased, but it for the entire fire hydrant systems, or the ratio of minimal, and it can make the entire hydrant system greatly enhanced the safety of this investment is worth it.
