如今，在消防工程中，消防信號(hào)蝶閥的使用越來(lái)越廣泛，但有時(shí)施工安裝方在安裝、施工、調(diào)試過(guò)程中偶爾會(huì)出現(xiàn)投訴。投訴內(nèi)容基本是無(wú)信號(hào)、長(zhǎng)信號(hào)等情況。讓我們找出以下情況。
Nowadays, in fire engineering, fire signal butterfly valve is used more and more widely, but sometimes the construction and installation party will occasionally complain during installation, construction and commissioning. The complaint content is basically no signal, long signal, etc. Let's find out the following.
消防信號(hào)蝶閥的信號(hào)是通過(guò)微動(dòng)開(kāi)關(guān)觸點(diǎn)的通斷原理實(shí)現(xiàn)的。微動(dòng)開(kāi)關(guān)本身質(zhì)量問(wèn)題導(dǎo)致的信號(hào)蝶閥故障可能會(huì)出現(xiàn)，但產(chǎn)品不合格的概率很低。要判斷是否是微動(dòng)開(kāi)關(guān)的質(zhì)量問(wèn)題，簡(jiǎn)單的方法就是用萬(wàn)用表測(cè)量，看看微動(dòng)開(kāi)關(guān)的阻值。
The signal of fire signal butterfly valve is realized through the on-off principle of microswitch contact. The signal butterfly valve failure caused by the quality problem of the microswitch itself may occur, but the probability of product failure is very low. To judge whether it is the quality problem of the microswitch, a simple way is to use a multimeter to measure and see the resistance value of the microswitch.
測(cè)量人員可以先用電表測(cè)量焊接連接的微動(dòng)開(kāi)關(guān)的一對(duì)觸點(diǎn)，記錄電阻值，然后用手指按動(dòng)微動(dòng)開(kāi)關(guān)的觸點(diǎn)簧片，然后測(cè)量這對(duì)觸點(diǎn)，如果電阻值有變化，則可以判斷微動(dòng)開(kāi)關(guān)功能正常，質(zhì)量沒(méi)有問(wèn)題。如有必要，重復(fù)測(cè)試幾次以進(jìn)行驗(yàn)證。
The measuring personnel can first measure a pair of contacts of the microswitch connected by welding with an electric meter, record the resistance value, then press the contact reed of the microswitch with his finger, and then measure the pair of contacts. If the resistance value changes, it can be judged that the microswitch function is normal and the quality is OK. If necessary, repeat the test several times to verify.
如果能驗(yàn)證微動(dòng)開(kāi)關(guān)功能正常，閥門(mén)啟閉信號(hào)仍不輸出，則可考慮信號(hào)蝶閥啟閉是否到位。無(wú)論是通過(guò)移動(dòng)手柄來(lái)開(kāi)啟和關(guān)閉閥瓣的信號(hào)閥，還是通過(guò)渦輪蝸桿驅(qū)動(dòng)開(kāi)啟和關(guān)閉閥瓣的信號(hào)閥，都是通過(guò)改變凹形凸輪的距離來(lái)實(shí)現(xiàn)信號(hào)輸出的。
If it can be verified that the microswitch function is normal and the valve opening and closing signal is still not output, it can be considered whether the signal butterfly valve is opened and closed in place. Whether the signal valve of the disc is opened and closed by moving the handle or the signal valve of the disc is opened and closed by driving the worm, the signal output is realized by changing the distance of the concave cam.
使微動(dòng)開(kāi)關(guān)的觸點(diǎn)打開(kāi)和關(guān)閉。因此，遇到這種現(xiàn)象后，施工調(diào)試人員可以用萬(wàn)用表在信號(hào)閥全關(guān)或全開(kāi)的情況下進(jìn)行測(cè)試。如果電阻表還是沒(méi)有變化，打開(kāi)信號(hào)蝶閥傳動(dòng)部分的防塵蓋，觀察凹形凸輪轉(zhuǎn)動(dòng)時(shí)凹形凸輪與微動(dòng)開(kāi)關(guān)簧片的接觸距離。
Open and close the contacts of the microswitch. Therefore, after encountering this phenomenon, the construction and commissioning personnel can use a multimeter to test when the signal valve is fully closed or fully open. If the ohmmeter still does not change, open the dust cover of the transmission part of the signal butterfly valve and observe the contact distance between the concave cam and the reed of the microswitch when the concave cam rotates.
可能由于搬運(yùn)、運(yùn)輸、安裝操作不當(dāng)，以及外力，如碰撞、振動(dòng)等，使微動(dòng)開(kāi)關(guān)的距離發(fā)生偏移和變化，導(dǎo)致接觸不良。如果確認(rèn)微動(dòng)開(kāi)關(guān)的距離偏移發(fā)生變化，調(diào)整固定微動(dòng)開(kāi)關(guān)的兩個(gè)小螺絲，適當(dāng)調(diào)整微動(dòng)開(kāi)關(guān)的距離。凹形凸輪體隨凹凸面移動(dòng)，使微動(dòng)開(kāi)關(guān)的觸點(diǎn)隨著凹凸面的變化而被按下（接通）或釋放（斷開(kāi)）。
The distance of the microswitch may shift and change due to improper handling, transportation and installation, as well as external forces, such as collision and vibration, resulting in poor contact. If the distance offset of the microswitch is confirmed to change, adjust the two small screws that fix the microswitch and adjust the distance of the microswitch appropriately. The concave cam body moves with the concave convex surface, so that the contact of the microswitch is pressed (connected) or released (disconnected) with the change of the concave convex surface.
川消小編提醒您微動(dòng)開(kāi)關(guān)本身的問(wèn)題或微動(dòng)開(kāi)關(guān)與凹形凸輪接觸距離造成的原因除外。應(yīng)更加注意信號(hào)輸出或顯示系統(tǒng)的質(zhì)量，因?yàn)樾盘?hào)輸出顯示系統(tǒng)的故障率普遍較高。如果這部分出現(xiàn)問(wèn)題，應(yīng)該對(duì)癥處理，不需要考慮信號(hào)蝶閥的問(wèn)題。
Chuanxiao Xiaobian reminds you of the problem of the microswitch itself or the contact distance between the microswitch and the concave cam. More attention should be paid to the quality of signal output or display system, because the failure rate of signal output and display system is generally high. If there is a problem in this part, it should be treated symptomatically, without considering the problem of signal butterfly valve.
