雨淋报警阀是一种采用杠杆式阀辨组件具有防复位功能的单向阀，平日里我们已经不会轻易使用，但要知道它是怎么回事，比如说它的安装和调试一定是要了解的，下面来简单了解了解吧。

Deluge alarm valve is a kind of one-way valve with anti reset function by using lever valve identification component. We won't use it easily in ordinary days, but we need to know what's going on. For example, its installation and debugging must be understood. Let's have a brief understanding.

1.安装：

1. Installation:

1）雨淋报警阀安装前必须进行密封试验，试验步骤是：二倍额定工作压力的静水压保持五分钟后，无渗漏变形，自锁和复位机构性能可靠，并仔细阅读使用说明书，对照工作环境温度、施工要求和介质等是否符合，方可投入安装。

1) The sealing test must be carried out before the installation of the deluge alarm valve. The test steps are as follows: after the hydrostatic pressure of twice the rated working pressure is maintained for five minutes, there is no leakage and deformation, and the performance of the self-locking and resetting mechanism is reliable. Read the operation manual carefully and check whether the working environment temperature, construction requirements and media meet the requirements before it can be put into installation.

2）安装前，供水系统和自动喷水灭火系统管网的管路，必须进行试压冲洗，验收合格方能安装，安装位置应考虑维修、保养的空间、便于操作。有冰冻的地区，雨淋报警阀应安装在有通风设备的室内，保证管路不会被冻住。

2) Before installation, the pipelines of water supply system and automatic sprinkler system pipe network must be pressure tested and flushed, and can be installed only after passing the acceptance. The installation position should consider the space for maintenance and easy operation. In frozen areas, the deluge alarm valve should be installed in the room with ventilation equipment to ensure that the pipeline will not be frozen.

3）本阀应垂直安装在相应的管路上，雨淋报警阀通管道两头，宜各安装一台带有启闭信号的消防蝶阀，便于操作，维修和调试。本公司有ZSXF·D型的手动蜗轮传动的信号蝶阀配套。

3) The valve should be installed vertically on the corresponding pipeline. The deluge alarm valve should be installed at both ends of the pipeline, and a fire butterfly valve with opening and closing signal should be installed respectively, which is convenient for operation, maintenance and commissioning. The company has zsxf · D type signal butterfly valve with manual worm gear transmission.

2.调试：

2. Commissioning:

1）排水试验：

1) Drainage test:

先查看雨淋报警阀排水阀在关闭时供水压力表的读数并作出记录，然后缓慢打开，应有稳定的水流出，此时读数略有下降但稳定，记录两读数的差，反复测量几次，其差不大，说明供水正常，如果相差太大，说明供水管路不畅，重新检查有否堵塞。

First check the reading of the water supply pressure gauge when the deluge alarm valve and drain valve are closed and make a record. Then open it slowly and there should be stable water outflow. At this time, the reading decreases slightly but is stable. Record the difference between the two readings and measure it repeatedly for several times. The difference is not big, indicating that the water supply is normal. If the difference is too big, indicating that the water supply pipeline is not smooth, recheck whether it is blocked.

2）报警试验：

2) Alarm test:

关闭报警管路的球阀，打开报警试验球阀，供水管路水直接流入水力警铃，此时水力警铃应发出声音报警，压力开关应有动作。试验后打关闭，恢复原状。

Close the ball valve of the alarm pipeline, open the alarm test ball valve, and the water in the water supply pipeline directly flows into the hydraulic alarm bell. At this time, the hydraulic alarm bell should sound an alarm, and the pressure switch should act. Close it after the test and restore it to its original state.

3）阀瓣开启动能试验：

3) Disc opening kinetic energy test:

川消小编认为阀瓣应处于伺应状态：

Chuanxiao Xiaobian believes that the valve clack should be in a waiting state:

a.电动开启：用电控装置使电磁阀动作，阀瓣应能开启（适用于电控系统）。

a. Electric opening: use the electric control device to make the solenoid valve act, and the valve flap should be able to open (applicable to the electric control system).

b.自动开启：打开自动喷水灭火系统管网中的末端试水装置，阀瓣自动开启（适用于湿式系统）。

b. Automatic opening: open the end water test device in the pipe network of the automatic sprinkler system, and the valve disc will open automatically (applicable to the wet system).

c.打开带有一定气压管网的未端试水装置，管网内气压下降，压力开关发出信号传电控箱，电控箱处理后使电磁阀开启（适用于干式系统）。

c. Open the end water test device with a certain air pressure pipe network, the air pressure in the pipe network drops, and the pressure switch sends a signal to the electric control box. After the electric control box is processed, the solenoid valve is opened (applicable to dry-type system).

以上三项试验时，水力警铃、压力开关都应有动作，这样才能更为方便的观察，更多信息就来关注我们网站http://www.cx-fire.com，为您介绍更多设备的使用安装与调试。

During the above three tests, the hydraulic alarm bell and pressure switch should all act, so that it can be more convenient to observe. For more information, please pay attention to our website http://www.cx-fire.com , to introduce you to the use, installation and debugging of more devices.
