消防水泵在消防給水系統(tǒng)中的作用相當(dāng)于人的心臟，是所有水系統(tǒng)的動(dòng)力所在，故消防水泵相關(guān)知識(shí)一定要認(rèn)真掌握，做到靈活運(yùn)用。下面
川消小編就來為您講解下消防水泵閥門設(shè)置的6點(diǎn)操作。
The role of fire pump in fire water supply system is equivalent to human heart, and it is the power of all water systems. Therefore, relevant knowledge of fire pump must be carefully mastered and flexibly used. Next, Sichuan Xiaobian will explain the six point operation of fire pump valve setting.
1、消防水泵的吸水管上應(yīng)設(shè)置明桿閘閥或帶自鎖裝置的蝶閥，但當(dāng)設(shè)置暗桿閥門時(shí)應(yīng)設(shè)有開啟刻度和標(biāo)志；當(dāng)管徑超過DN300時(shí)，宜設(shè)置電動(dòng)閥門；
1. The rising stem gate valve or butterfly valve with self-locking device shall be set on the suction pipe of the fire pump, but the opening scale and sign shall be set when the non rising stem valve is set; When the pipe diameter exceeds DN300, electric valve should be set;
2、消防水泵的出水管上應(yīng)設(shè)止回閥、明桿閘閥或帶自鎖裝置的蝶閥，但當(dāng)設(shè)置暗桿閥門時(shí)應(yīng)設(shè)有開啟刻度和標(biāo)志；當(dāng)管徑大于DN300時(shí)，宜設(shè)置電動(dòng)閥門；
2. Check valve, rising stem gate valve or butterfly valve with self-locking device shall be set on the outlet pipe of the fire pump, but the opening scale and sign shall be set when the non rising stem valve is set; When the pipe diameter is greater than DN300, electric valve should be set;
3、消防水泵吸（出）水管水平段，變徑連接時(shí)，應(yīng)采用偏心異徑管管頂平接；
3. For the horizontal section of the fire pump suction (outlet) pipe, the eccentric reducer pipe top shall be used for parallel connection;
4、過濾器的過水面積應(yīng)大于管道過水面積的4倍，且孔徑大于等于3mm；
4. The discharge area of the filter shall be 4 times greater than the discharge area of the pipe, and the aperture shall be no less than 3mm;
5、消火栓給水系統(tǒng)與自動(dòng)噴水滅火系統(tǒng)宜分別設(shè)置消防水泵，當(dāng)與消火栓系統(tǒng)合用消防水泵時(shí)，系統(tǒng)管道應(yīng)在報(bào)警閥前分開；
5. The fire pump should be set for the fire hydrant water supply system and the automatic sprinkler system respectively. When the fire pump is shared with the fire hydrant system, the system pipe should be separated in front of the alarm valve;
6、消防水泵吸水管的直徑小于DN250時(shí)，其流速宜為1.0m/s～1.2m/s；直徑大于DN250時(shí)，宜為1.2m/s～1.6m/s；
6. When the diameter of the fire pump suction pipe is less than DN250, the flow rate should be 1.0m/s-1.2m/s; When the diameter is greater than DN250, it should be 1.2m/s ～ 1.6m/s;
That's all for the 6 o'clock operation of fire pump valve setting. You can come to our website at any time if you have any needs http://m.xintli.net Ask about it!
