Fire hydrant valve belongs to shock wave valve. Valve is the control part of the fluid conveying system. It has the functions of cut-off, regulation, diversion, countercurrent prevention, stabilization, diversion or overflow relief. So how to replace the indoor fire hydrant valve? We need the safety observer of Baibai safety net to give you a detailed introduction.
The valve of indoor fire hydrant generally adopts open pole flange gate valve. Fire hydrant valve is an important accessory of industrial and architectural pipeline control. This lecture is more important than the practical application of fire hydrant valve. Fire hydrant valve consists of valve body, opening and closing mechanism and valve cover. When replacing the hydrant valve, the main valve must be closed in order to replace it. You can't replace it without releasing water. There are fire hydrants on each floor and there is no other way to deal with them.
The indoor fire water supply pipeline shall be divided into several independent sections by valves. For single-storey factories (warehouses) and public buildings, no more than five hydrants should be stopped for overhaul. For multi-storey civil buildings and other factories (warehouses), the arrangement of valves in indoor fire water supply pipelines should ensure that no more than one vertical pipe is closed when the pipeline is repaired, but two vertical pipes can be closed when the number of vertical pipes is more than three.
Valves should be kept open regularly, and should have obvious opening and closing signs or signals; (The latter clause explains that fire valves should be installed on fire pipelines. The valve arrangement in the annular pipe network should ensure that the necessary water for fire protection is still available when the pipe network is repaired. The number of fire hydrants between two valves in the indoor fire pipe network of a single-storey factory building (warehouse) should not exceed 5. When arranging the valves of fire water supply pipe network in multi-storey, high-rise factory buildings (warehouses) and multi-storey civil buildings, we should try to ensure that one of the vertical pipes can still supply all the water for fire protection when it is overhauled. )
