末端試水裝置為什么大部分都設(shè)置在廁所里？

在日常的消防維保工作中,，有一個(gè)東西是肯定要查看的,，那就是末端試水裝置。那么真正的末端試水裝置是咱們平時(shí)見到的樣子嗎,？為什么大部分都設(shè)置在廁所里？諸多問題且聽
川消小編一一道來,。
In daily fire maintenance work, there is one thing that must be checked, which is the end water testing device. So is the real end water testing device what we usually see? Why are most of them set up in the restroom? Many questions, let's listen to the editor of Chuanxiao.
在整個(gè)噴淋系統(tǒng)中,，有的噴頭距離濕式報(bào)警閥很近，有的則離的很遠(yuǎn),，高度差也有大有小,，距離報(bào)警閥較遠(yuǎn)的噴頭爆裂后系統(tǒng)的反應(yīng)就會(huì)遲鈍，要想測試整個(gè)系統(tǒng)的任何一個(gè)噴頭的爆裂是否都會(huì)正常的及時(shí)啟動(dòng)系統(tǒng),，就必須要找到這個(gè)不利點(diǎn),，在這個(gè)點(diǎn)進(jìn)行測試能啟動(dòng)系統(tǒng)，才能代表整個(gè)系統(tǒng)處于正常狀態(tài),。
In the entire sprinkler system, some nozzles are very close to the wet alarm valve, while others are far away, with varying height differences. After the nozzle far from the alarm valve bursts, the system's response will become sluggish. To test whether any nozzle burst in the entire system will start the system normally and in a timely manner, it is necessary to find this unfavorable point and conduct testing at this point to start the system, Only then can it represent that the entire system is in a normal state.
在噴淋系統(tǒng)中這個(gè)不利點(diǎn)一般都是在高樓層的偏僻的角落,，在這個(gè)點(diǎn)安裝末端試水裝置，就能測試出系統(tǒng)的可靠性了,。就是說,，如果這個(gè)點(diǎn)的噴頭爆裂都可以啟動(dòng)系統(tǒng)，那么其他位置的噴頭發(fā)生爆裂就更能啟動(dòng)系統(tǒng)了,。
In the sprinkler system, this disadvantage is usually found in remote corners of high floors. By installing an end water testing device at this point, the reliability of the system can be tested. That is to say, if the nozzle at this point bursts, the system can be activated, and if the nozzle at other positions bursts, the system can be activated even more.
規(guī)范說：末端試水裝置的出水,，應(yīng)采取孔口出流的方式排入排水管道 。就是說放水的時(shí)候,，眼睛要能看到水在嘩嘩的往外流,，不能直接連上一根管子直接排走（如果這樣的話管子被堵住了都不知道，測試結(jié)果也就不可靠了）,。
The specification states that the outlet of the end water testing device should be discharged into the drainage pipeline through the orifice. That is to say, when releasing water, the eyes should be able to see the water splashing outward, and cannot directly connect a pipe to discharge it (if this happens, the pipe is blocked and the test results are unreliable).
就是說這個(gè)地方要有下水管,，如果沒有下水管，你平時(shí)去檢測還會(huì)隨便放水嗎,？相當(dāng)于變相給測試增加了障礙,。大家都知道，一個(gè)辦公樓的辦公室里幾乎不會(huì)設(shè)置下水裝置,，好的選擇就是在廁所里,。
That means this place needs to have a drainage pipe. If there is no drainage pipe, do you still discharge water casually when you go for testing? Equivalent to adding obstacles to testing in disguise. As we all know, there is almost no drainage system installed in the office of an office building, and a good choice is to use the toilet.
找到了末端試水裝置之后，你會(huì)在其他樓層的相同位置看到試水閥,。試水閥就沒有要求裝試水接頭,，這是因?yàn)槠渌麡菍拥脑囁y的作用是測試該層噴淋系統(tǒng)的水流指示器的。
After finding the end water testing device, you will see the water testing valve at the same location on other floors. The water testing valve does not require the installation of a water testing joint, because the function of the water testing valves on other floors is to test the water flow indicator of the spray system on that floor.
在試水閥處放水，該層噴淋系統(tǒng)內(nèi)的水就會(huì)產(chǎn)生流動(dòng),，沖擊水流指示器,，觸發(fā)微動(dòng)開關(guān)，給消防主機(jī)一個(gè)反饋信號(hào),，就能知道水流指示器是否能正常報(bào)警了,。所以你如果看到其他樓層的試水閥上沒有壓力表，不要說人家忘了裝了,，是真沒必要安裝壓力表,，也不用控制流量 。
When water is discharged at the water testing valve, the water in the spray system of this layer will flow, impact the water flow indicator, trigger the microswitch, and give a feedback signal to the fire host to determine whether the water flow indicator can alarm normally. So if you see that there is no pressure gauge on the water testing valve on other floors, don't say they forgot to install it. It's really unnecessary to install a pressure gauge or control the flow.
此外水流指示器前面都有一個(gè)信號(hào)蝶閥,，規(guī)范規(guī)定兩者的距離不得小于30厘米,，這樣做的原因，是怕距離太近,，信號(hào)蝶閥的閥板會(huì)造成水流的紊流現(xiàn)象,，影響水流指示器的正常反饋。所以試水閥放水后水流指示器不反饋還有可能是信號(hào)蝶閥被關(guān)閉了,。還有什么事項(xiàng)就來我們網(wǎng)站

In addition, there is a signal butterfly valve in front of the water flow indicator, and the specification stipulates that the distance between the two should not be less than 30 centimeters. The reason for doing so is to be afraid that the valve plate of the signal butterfly valve may cause turbulence in the water flow, affecting the normal feedback of the water flow indicator. So if the water flow indicator does not provide feedback after the water test valve is drained, it is possible that the signal butterfly valve has been closed.
