消防水泵在消防给水系统中的作用相当于人的心脏，是所有水系统的动力所在，故消防水泵相关知识一定要认真掌握，做到灵活运用。下面川消小编就来为您讲解下消防水泵阀门设置的6点操作。

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应设置明杆闸阀或带自锁装置的蝶阀，但当设置暗杆阀门时应设有开启刻度和标志；当管径超过DN300时，宜设置电动阀门；

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应设止回阀、明杆闸阀或带自锁装置的蝶阀，但当设置暗杆阀门时应设有开启刻度和标志；当管径大于DN300时，宜设置电动阀门；

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，变径连接时，应采用偏心异径管管顶平接；

3. For the horizontal section of the fire pump suction (outlet) pipe, the eccentric reducer pipe top shall be used for parallel connection;

4、过滤器的过水面积应大于管道过水面积的4倍，且孔径大于等于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、消火栓给水系统与自动喷水灭火系统宜分别设置消防水泵，当与消火栓系统合用消防水泵时，系统管道应在报警阀前分开；

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径小于DN250时，其流速宜为1.0m/s～1.2m/s；直径大于DN250时，宜为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;
