消火栓系统中的压力开关与流量之间有什么关系?

来源:http://www.cx-fire.com/ 日期:2023-11-23

建筑消火栓给水系统是消防水池内的水,经过加压(外网压力不满足需要时,采用市政管网直接吸水),输送到用于扑灭建筑物内的火灾而设置的固定灭火设备,是建筑物中.基本的灭火设施。
The building fire hydrant water supply system is a fixed fire extinguishing equipment set up to extinguish fires inside the building, which is the basic fire extinguishing facility in the building. The water in the fire pool is pressurized (when the external network pressure does not meet the needs, the municipal pipeline network is used to directly absorb water) and transported to it.
压力开关、流量开关的作用
The function of pressure switch and flow switch
消防水泵出水干管上设置的压力开关、高位消防水箱出水管上设置的流量开关等开关信号应能直接自动启动消防水泵。
The pressure switch set on the main outlet pipe of the fire pump and the flow switch set on the outlet pipe of the high-level fire water tank should be able to automatically start the fire pump directly.

压力开关、流量开关的开关信号启动消防泵的控制方式可靠性较高,替代以往采用的可能误操作、投资多的消防按钮的控制方式。
The control method of starting the fire pump with the switch signals of pressure switches and flow switches has high reliability, replacing the previously used control method of fire buttons that may be operated incorrectly and have high investment.
关于压力开关、流量开关的条文解释
Explanation of articles on pressure switches and flow switches
“压力开关一般可采用电接点压力表、压力传感器等”
Pressure switches can generally use electric contact pressure gauges, pressure sensors, etc
流量开关 “应能在管道流速为 0.1m/s~10m/s 时可靠启动。”
The flow switch should be able to reliably start when the pipeline flow rate is between 0.1m/s and 10m/s
存在问题
Existing problems
压力开关并不是电接点压力表、压力传感器的统称,电接点压力表与压力传感器有所区别;
Pressure switch is not a general term for electric contact pressure gauge and pressure sensor, and there is a difference between electric contact pressure gauge and pressure sensor;
流量开关,没有规定其发出自动启动开关信号的.小及.大流量;
The flow switch does not specify a small or large flow rate that emits an automatic start switch signal;
