如今，專門來生產末端試水裝置的企業非常多，尤其是那些未來有前景的末端試水裝置??生產企業更受人們的歡迎與認可，這些企業生產出來的末端試水裝置質量優異，使用效果非常突出并且壽命長，那么這種末端試水裝置的主要作用是什么呢？下面
川消小編為您講解一番。
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.作用是檢驗系統的可靠性，測試系統能否在開放一只噴頭的不利條件下可靠報警并正常啟動。同時可測試干式系統和預作用系統的管道充水時間。
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.末端試水裝置由試水閥、壓力表及試水接頭等組成。
2. The end water test device is composed of water test valve, pressure gauge and water test joint.
3.每個報警閥組控制的不利點噴頭處應設置末端試水裝置，其他防火分區和樓層均應設置直徑為25mm的試水閥。
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.試水接頭出水口的流量系數應與同樓層或同防火分區內選用的小流量系數的噴頭相等。其出水應采用孔口出流的方式排入排水管道。排水立管宜設置伸頂通氣管，其管徑不應小于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.
此次末端試水裝置的往凈檢查分為外觀檢查和功能檢查：
The cleaning inspection of the end water testing device is divided into appearance inspection and function inspection:
外觀檢查主要包括外觀標識和外觀質量檢查。末端試水裝置要有清晰的銘牌、操作指示標識和產品說明書。水流指示器上有水流方向的性標識；末端試水裝置的試水閥上有明顯的啟閉狀態標識。
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.
功能檢查主要是檢查末端試水裝置的密封性能，試驗壓力為工作壓力的1.1倍，穩壓5分鐘，無泄漏即可。
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.
末端試水裝置手動（電動）操作方式靈活，便于開啟，信號反饋裝置能夠在末端試水裝置開啟后輸出信號，試水閥關閉后，末端試水裝置無滲漏。
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.
末端試水裝置的主要作用除了檢查配水管道是否暢通之外，還可以檢查師是系統是否可靠，另外也可以對壓力開關、水流指示器以及水利警鈴的工作狀態進行檢驗，可見適中的末端試水裝置?對于水利工程來說是一項非常重要的儀器，因此不可或缺。你有需求就來我們網站
