礦用無壓風門

ꄴ上一個：無

ꄲ下一個：礦用避難硐室門

無壓風門用于井下進回風巷和主要進回風巷之間的每個聯(lián)絡(luò)巷中，是保障礦井風流正常流通而研制的專用設(shè)備,開啟力小，無需再設(shè)反向風門，人和車過后，能自動關(guān)閉，是目前我國煤礦井下較為理想的一種風門。

本無壓風門是我廠自主開發(fā)，產(chǎn)品質(zhì)量標準和檢測標準嚴格執(zhí)行國家相關(guān)規(guī)定要求。一般一套為 2 道門，根據(jù)閉鎖結(jié)構(gòu)可分為機械閉鎖式、氣動閉鎖式、電氣閉鎖式和電液閉鎖式四種。

無壓風門安裝說明：

1、安裝前準備工作

（1）確定門的型號、尺寸和配置；

（2）檢查門洞尺寸、墻體結(jié)構(gòu)及地面高度是否符合安裝要求；

（3）準備安裝所需工具和材料，比如電動螺絲刀、膨脹螺栓、內(nèi)六角扳手等。

2、安裝步驟及注意事項

（1）測量門洞的高寬，將風門放入門洞中，并進行初步調(diào)整，使門與門洞的垂直度及水平度達到標準。

（2）確認門洞結(jié)構(gòu)類型，選擇合適的安裝方法，如使用膨脹螺栓固定。鋼結(jié)構(gòu)門洞應(yīng)采取鋼梁埋嵌加固或冷彎成型的加固方式。混凝土結(jié)構(gòu)門洞應(yīng)采用鉆孔加粘鉤加固。

（3）確認安裝位置，打好安裝孔，固定門，保證門與門洞有一個密封空間。

（4）進行風門的外觀檢查，確保門面平整、無明顯變形、色差和劃痕等。

（5）進行空氣密封性測試，即用煙霧機將煙霧噴入門縫縫隙，檢查門的密閉性。

3、安裝后的驗收

（1）檢查門的開閉情況，確保門輕松開關(guān)，不卡頓、不變形、不銹蝕等。

（2）測試門的通風、防突性能，確保門在強風等極端條件下，能夠保持建筑內(nèi)外空氣壓平衡。

（3）進行安全性能測試，確保門對震動、撞擊等外力有足夠的承受能力。

4、注意事項

（1）門的安裝需由專業(yè)人員進行，確保安裝的準確性和安全性。

（2）門的檢驗、維修、保養(yǎng)應(yīng)按照安裝部位、使用頻度、環(huán)境條件等特點進行，并有明確的記錄。

（3）門的使用過程中，應(yīng)注意每次關(guān)閉時門的密封性能，維護常開狀態(tài)下的門，確保外侵和風阻的平衡性。

（4）風門要由專人維護使用，初次安裝或使用應(yīng)完整閱讀使用說明書。

（5）按規(guī)定的時間期限對風門靈活度、密封性進行調(diào)節(jié)，定期清洗風門，保持良好的通風形象。

（6）檢查風門閉鎖的可靠性，不可有故障瞞報漏報的現(xiàn)象，風流有序流通是煤礦安全作業(yè)的基本條件，任何人員不得違章破壞風門。
