盲板閥的類型和工作原理

盲板閥是一(yi)種手動(dong)、電(dian)動(dong)、氣動(dong)或液(ye)壓(ya)切斷氣體介質的閘閥(fa)(fa)(fa)。一(yi)般分(fen)為電(dian)動(dong)盲板閥(fa)(fa)(fa)、液(ye)壓(ya)盲板閥(fa)(fa)(fa)、氣動(dong)盲板閥(fa)(fa)(fa)和電(dian)動(dong)開式盲板閥(fa)(fa)(fa)。

盲板閥的(de)驅(qu)動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)有三種(zhong)(zhong)，其中有兩種(zhong)(zhong)手(shou)動(dong)夾(jia)(jia)緊或(huo)(huo)釋(shi)(shi)放裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)，一種(zhong)(zhong)是(shi)打(da)開或(huo)(huo)關(guan)閉百葉(xie)窗(chuang)的(de)電動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)。在打(da)開或(huo)(huo)關(guan)閉快(kuai)門時(shi)，首先(xian)釋(shi)(shi)放兩個(ge)手(shou)動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)，然后啟動(dong)電動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)打(da)開或(huo)(huo)關(guan)閉快(kuai)門(特別注意(yi)：如果兩個(ge)手(shou)動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)未釋(shi)(shi)放，則不得(de)打(da)開電動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi))。開閉器(qi)打(da)開或(huo)(huo)關(guan)閉后，夾(jia)(jia)緊兩個(ge)手(shou)動(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)(zhi)，管道(dao)才(cai)能(neng)繼(ji)續。

盲(mang)板(ban)(ban)閥(fa)(fa)(fa)由(you)左右閥(fa)(fa)(fa)體、伸縮機構和(he)扇(shan)形體組成。盲(mang)板(ban)(ban)閥(fa)(fa)(fa)分為電動盲(mang)板(ban)(ban)閥(fa)(fa)(fa)、氣動盲(mang)板(ban)(ban)閥(fa)(fa)(fa)、液壓盲(mang)板(ban)(ban)閥(fa)(fa)(fa)、開式(shi)插(cha)板(ban)(ban)閥(fa)(fa)(fa)和(he)閉(bi)式(shi)插(cha)板(ban)(ban)閥(fa)(fa)(fa)。之前已經詳細(xi)分析了開啟和(he)關閉(bi)閘(zha)板(ban)(ban)閥(fa)(fa)(fa)。下面詳細(xi)介紹幾種盲(mang)板(ban)(ban)閥(fa)(fa)(fa)：

1、F943X電(dian)動扇形(xing)盲板閥(fa)，屬于自動扇形(xing)盲板閥(fa)產品。它由夾緊驅動裝置、閥(fa)瓣(ban)和(he)閥(fa)體(ti)組(zu)成。主要用于工礦行業作為冶金(jin)閥(fa)門的切割(ge)裝置。該閥(fa)可(ke)由單個單元(yuan)或(huo)多個單元(yuan)遠程控制，特殊情況下(xia)可(ke)手動操作。結構體(ti)由底座(zuo)和(he)支(zhi)撐柱組(zu)成，具(ju)有(you)穩定性(xing)高的特點；在閥(fa)板上，密(mi)封圈具(ju)有(you)密(mi)封性(xing)能高等(deng)優點。

2、F743X液壓(ya)扇形(xing)盲板(ban)(ban)(ban)(ban)閥(fa)主要由(you)左(zuo)閥(fa)體(ti)、右閥(fa)體(ti)、螺桿、閘板(ban)(ban)(ban)(ban)、密封圈(quan)、杠桿、液壓(ya)缸(gang)(gang)等部分組成(cheng)，底座和(he)(he)支撐柱組成(cheng)剛(gang)性結構。該(gai)閥(fa)門設有夾緊(jin)釋(shi)放(fang)缸(gang)(gang)和(he)(he)翻板(ban)(ban)(ban)(ban)缸(gang)(gang)，夾緊(jin)釋(shi)放(fang)缸(gang)(gang)通過杠桿和(he)(he)螺桿驅動(dong)(dong)左(zuo)右閥(fa)體(ti)完成(cheng)松開和(he)(he)夾緊(jin)動(dong)(dong)作(zuo)，翻板(ban)(ban)(ban)(ban)缸(gang)(gang)驅動(dong)(dong)閘板(ban)(ban)(ban)(ban)完成(cheng)開啟和(he)(he)關閉動(dong)(dong)作(zuo)。

3、F643X氣(qi)動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)是一種自動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)，其驅動(dong)(dong)(dong)方(fang)式為(wei)氣(qi)動(dong)(dong)(dong)，故又稱氣(qi)動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)。F643X氣(qi)動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)有四種閥(fa)(fa)(fa)門，分別是F643X-0.5氣(qi)動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)、F643X-1.5氣(qi)動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)、F643X-1.0氣(qi)動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)和F643X-2.0氣(qi)動(dong)(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)閥(fa)(fa)(fa)。

4、F643X氣動(dong)(dong)扇(shan)形盲板閥(fa)可自動(dong)(dong)遙控。它由左(zuo)(zuo)閥(fa)體、右(you)閥(fa)體、中閥(fa)體和三個連接(jie)螺釘組成(cheng)。用(yong)扳手轉(zhuan)動(dong)(dong)連接(jie)螺絲，左(zuo)(zuo)右(you)閥(fa)體就可以夾緊和松開(kai)，通(tong)過改(gai)變百(bai)葉窗上(shang)的盲板和通(tong)孔板的位置(zhi)就可以實現開(kai)啟和關閉。該(gai)閥(fa)具有(you)結構簡單、重量輕、性能可靠(kao)、操作(zuo)方(fang)便的特點。該(gai)閥(fa)為(wei)一系列短(duan)結構，左(zuo)(zuo)右(you)閥(fa)體上(shang)分別(bie)安裝橡膠密封圈。
