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.

壓力開關(guān)、流量開關(guān)的作用

The function of pressure switch and flow switch

消防水泵出水干管上設(shè)置的壓力開關(guān)、高位消防水箱出水管上設(shè)置的流量開關(guān)等開關(guān)信號應(yīng)能直接自動啟動消防水泵。

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.

壓力開關(guān)、流量開關(guān)的開關(guān)信號啟動消防泵的控制方式可靠性較高，替代以往采用的可能誤操作、投資多的消防按鈕的控制方式。

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.

關(guān)于壓力開關(guān)、流量開關(guān)的條文解釋

Explanation of articles on pressure switches and flow switches

“壓力開關(guān)一般可采用電接點壓力表、壓力傳感器等”

Pressure switches can generally use electric contact pressure gauges, pressure sensors, etc

流量開關(guān) “應(yīng)能在管道流速為 0.1m/s～10m/s 時可靠啟動。”

The flow switch should be able to reliably start when the pipeline flow rate is between 0.1m/s and 10m/s

存在問題

Existing problems

壓力開關(guān)并不是電接點壓力表、壓力傳感器的統(tǒng)稱，電接點壓力表與壓力傳感器有所區(qū)別；

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;

流量開關(guān)，沒有規(guī)定其發(fā)出自動啟動開關(guān)信號的.小及.大流量；

The flow switch does not specify a small or large flow rate that emits an automatic start switch signal;
