末端試水裝置是由試驗閥、試驗管和排水管、壓力表組成的。該裝置安裝在系統管網不利點噴頭處，檢驗系統啟動、報警及聯動等功能的裝置，下面來分享末端試水裝置的作用以及檢查內容。

The end water test device is composed of test valve, test pipe, drainage pipe and pressure gauge. The device is installed at the nozzle at the unfavorable point of the system pipe network to test the functions of system startup, alarm and linkage. Here are the functions and inspection contents of the end water test device.

川消末端試水裝置的作用：模擬噴淋系統各個保護區不利點處的噴頭工作時，水流指示器、報警閥與壓力開關、水利警鈴的聯動、復位性能。檢測不利點處噴頭真實的工作壓力是否到達到規定值。在規定時間內，不利點處的噴頭能否達到規范所規定的流量值。便于以后對管道沖洗及換水維護等。

Function of Chuanxiao end water test device: simulate the linkage and reset performance of water flow indicator, alarm valve, pressure switch and water conservancy alarm bell when the sprinkler at the adverse points of each protection area of the sprinkler system works. Check whether the real working pressure of the nozzle at the unfavorable point reaches the specified value. Whether the nozzle at the unfavorable point can reach the flow value specified in the specification within the specified time. It is convenient for pipeline flushing and water change maintenance in the future.

末端試水裝置的檢查分為外觀檢查和功能檢查。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。

The inspection of the end water test device is divided into appearance inspection and function inspection. Appearance inspection mainly includes appearance identification and appearance quality inspection. The end water test device shall be provided with clear nameplate, safe operation instruction mark and product manual. Permanent identification of water flow direction on the water flow indicator; The water test valve of the end water test device is marked with obvious opening and closing status.

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。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 function inspection is mainly to check the sealing performance of the end water test device. The test pressure is 1.1 times of the working pressure. It can be stabilized for 5 minutes without leakage. The manual (electric) operation mode of the end water test device is flexible and easy to open. The signal feedback device can output the signal after the end water test device is opened. After the water test valve is closed, the end water test device has no leakage.

末端試水裝置處排水設施的排水能力應進行測試，且在地面不應有積水。每個季度應對系統所有的末端試水閥和報警閥旁的放水實驗閥進行一次放水試驗，檢查系統啟動、報警功能以及出水情況是否正常。每月應利用末端試水裝置對水流指示器進行試驗。

The drainage capacity of the drainage facilities at the end water test device shall be tested, and there shall be no ponding on the ground. Every quarter, a water discharge test shall be conducted for all the end water test valves of the system and the water discharge test valve next to the alarm valve to check whether the system startup, alarm function and water outlet condition are normal. The water flow indicator shall be tested monthly using the end water test device.

測試末端試水裝置的密封性能，試驗壓力為額定工作壓力的1.1倍，保壓時間為5min，末端試水裝置試水閥關閉，測試結束時末端試水裝置個組件無滲漏。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。

Test the sealing performance of the end water test device, the test pressure is 1.1 times of the rated working pressure, the pressure holding time is 5min, the water test valve of the end water test device is closed, and there is no leakage in each component of the end water test device at the end of the test. The manual (electric) operation mode of the end water test device is flexible and easy to open. The signal feedback device can output the signal after the end water test device is opened. After the water test valve is closed, the end water test device has no leakage.

試水閥、試水噴嘴應采用耐腐蝕性能不低于黃銅的金屬材料制作。末端試水裝置應具有防止誤操作的措施，壓力表安裝口應設有開關。

The water test valve and nozzle shall be made of metal materials with corrosion resistance not lower than brass. The end water test device shall be provided with measures to prevent misoperation, and the installation port of the pressure gauge shall be equipped with a switch.

開啟末端試水裝置進行試驗時，測試得到的壓力和流量數據，只是在測試位置處的流量和壓力數據，并沒有經驗公式能利用此數據科學推算出系統供水能力（壓力、流量），更不能判斷系統的不利點壓力是否符合設計要求。末端試水裝置的真正功能是檢驗系統啟動、報警和利用系統啟動后的特性參數組成聯動控制裝置等的功能是否正常。

When the end water test device is opened for test, the pressure and flow data obtained from the test are only the flow and pressure data at the test position. There is no empirical formula to use this data to scientifically calculate the water supply capacity (pressure and flow) of the system, and it can not judge whether the pressure at the unfavorable point of the system meets the design requirements. The real function of the end water test device is to check whether the functions of system startup, alarm and linkage control device composed of characteristic parameters after system startup are normal.
