如今，专门来生产末端试水装置的企业非常多，尤其是那些未来有前景的末端试水装置??生产企业更受人们的欢迎与认可，这些企业生产出来的末端试水装置质量优异，使用效果非常突出并且寿命长，那么这种末端试水装置的主要作用是什么呢？下面川消小编为您讲解一番。

Nowadays, there are many enterprises specialized in producing end-of-pipe water testing devices, especially those with promising future?? The production enterprises are more popular and recognized by people. The end water testing devices produced by these enterprises are of excellent quality, outstanding use effect and long service life. What is the main role of this end water testing device? Next, Sichuan Xiaobian will explain it to you.

1.作用是检验系统的可靠性，测试系统能否在开放一只喷头的不利条件下可靠报警并正常启动。同时可测试干式系统和预作用系统的管道充水时间。

1. The function is to check the reliability of the system and test whether the system can reliably alarm and start normally under the adverse conditions of opening a nozzle. At the same time, it can test the pipe filling time of dry system and pre-action system.

2.末端试水装置由试水阀、压力表及试水接头等组成。

2. The end water test device is composed of water test valve, pressure gauge and water test joint.

3.每个报警阀组控制的不利点喷头处应设置末端试水装置，其他防火分区和楼层均应设置直径为25mm的试水阀。

3. The end water test device shall be set at the adverse point nozzle controlled by each alarm valve group, and the water test valve with diameter of 25mm shall be set in other fire zones and floors.

4.试水接头出水口的流量系数应与同楼层或同防火分区内选用的小流量系数的喷头相等。其出水应采用孔口出流的方式排入排水管道。排水立管宜设置伸顶通气管，其管径不应小于75mm。

4. The flow coefficient of the water test joint outlet shall be equal to the nozzle with small flow coefficient selected in the same floor or fire compartment. The outlet water shall be discharged into the drainage pipe through the orifice. The drainage riser should be equipped with a vent pipe with a diameter of not less than 75mm.

此次末端试水装置的往净检查分为外观检查和功能检查：

The cleaning inspection of the end water testing device is divided into appearance inspection and function inspection:

外观检查主要包括外观标识和外观质量检查。末端试水装置要有清晰的铭牌、操作指示标识和产品说明书。水流指示器上有水流方向的性标识；末端试水装置的试水阀上有明显的启闭状态标识。

Appearance inspection mainly includes appearance identification and appearance quality inspection. The end water testing device shall be provided with clear nameplate, safe operation indication and product instructions. The water flow indicator is provided with permanent identification of water flow direction; The water test valve of the end water test device has obvious opening and closing status identification.

功能检查主要是检查末端试水装置的密封性能，试验压力为工作压力的1.1倍，稳压5分钟，无泄漏即可。

The function check is mainly to check the sealing performance of the end water test device. The test pressure is 1.1 times of the working pressure, and the pressure is stabilized for 5 minutes, without leakage.

末端试水装置手动（电动）操作方式灵活，便于开启，信号反馈装置能够在末端试水装置开启后输出信号，试水阀关闭后，末端试水装置无渗漏。

The manual (electric) operation mode of the end water test device is flexible and easy to open. The signal feedback device can output signals after the end water test device is opened. After the water test valve is closed, the end water test device has no leakage.

末端试水装置的主要作用除了检查配水管道是否畅通之外，还可以检查师是系统是否可靠，另外也可以对压力开关、水流指示器以及水利警铃的工作状态进行检验，可见适中的末端试水装置?对于水利工程来说是一项非常重要的仪器，因此不可或缺。你有需求就来我们网站http://www.cx-fire.com咨询联系吧！

The main function of the end water test device is not only to check whether the water distribution pipeline is smooth, but also to check whether the system is reliable, and also to check the working status of the pressure switch, water flow indicator and water conservancy alarm bell. It can be seen that the end water test device with moderate price? It is a very important instrument for water conservancy projects, so it is indispensable.
