                                                                                                                                                                              七氟丙烷滅火系統分為有管網與無管網,無管網七氟丙烷滅火系統不需要設計管道輸送,而有管網七氟丙烷滅火系統是需要布置管道進行滅火劑的輸送,可以保護多個防火區,那么有管網七氟丙烷滅火系統是怎么將滅火劑準確地輸送到特定的防火區的呢?為了實現這樣的輸送,系統組件中的選擇閥以及單向閥具有非常重要的作用。
                                                                                                                                                                               
                                                                                                                                                                              選擇閥
                                                                                                                                                                              有管網七氟丙烷滅火系統選擇閥是系統的主要組件,為什么系統能準確將滅火劑輸送到指定的防火區,原因就在于它的作用。七氟丙烷滅火系統的選擇閥可以是兩個或者兩個以上,每個選擇閥對應著特定的防火區,這樣的設計可以為系統節省了滅火劑的用量,因此場所中滅火劑用量以最大防火區為設計標準來計算。

                                                                                                                                                                              有管網七氟丙烷滅火系統的單向閥分為液體單向閥以及氣控單向閥,液體單向閥與高壓軟管以及集流管連接,防止滅火劑倒流,能將滅火劑噴放到集流管通過管道輸送到防火區。氣控單向閥是啟動氣體管道上的的裝置是為了防止啟動氣體倒流,有效控制瓶頭閥以及選擇閥的啟開,確保了系統的正常啟動??梢哉f是氣控單向閥就是選擇閥的輔助性組件,選擇閥的正常開啟離不開氣控單向閥的作用。
