盲板閥型號及工作原理

盲板閥是一種手、電動或氣、液動切斷氣體介質的閘板閥，一般分為電動盲板閥、液動盲板閥、氣動盲板閥、封閉式插板閥、電動敞開式盲板閥。接下來由球一盲板閥廠家來具體講解盲板閥。

盲板閥共有三(san)個驅動裝置(zhi)，

盲板閥其(qi)中有兩(liang)個手(shou)動(dong)(dong)(dong)夾(jia)(jia)緊或松(song)開(kai)裝(zhuang)(zhuang)(zhuang)置(zhi)，一(yi)個為使閘(zha)板開(kai)通或者關閉的電動(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)，在開(kai)或關閘(zha)板中，首先松(song)開(kai)兩(liang)個手(shou)動(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)，而后再(zai)(zai)啟動(dong)(dong)(dong)電動(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)，以達到閘(zha)板開(kai)或關的目的(特(te)別注意(yi)：兩(liang)個手(shou)動(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)不松(song)開(kai)，不得開(kai)啟電動(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi))，閘(zha)板開(kai)或關完成后，再(zai)(zai)將兩(liang)個手(shou)動(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)夾(jia)(jia)緊，管道方能進行(xing)工作.

盲板(ban)(ban)(ban)閥(fa)由左、右閥(fa)體(ti)、伸縮(suo)機構、扇形閥(fa)板(ban)(ban)(ban)及驅動(dong)(dong)閥(fa)板(ban)(ban)(ban)的電動(dong)(dong)推桿(gan)Ⅰ和(he)夾緊、松(song)開的電動(dong)(dong)推桿(gan)Ⅱ組成。

關閥

電(dian)動(dong)推(tui)桿(gan)Ⅱ動(dong)作，密(mi)封副脫開(kai)，然后電(dian)動(dong)推(tui)桿(gan)Ⅰ動(dong)作，扇形閥(fa)板由開(kai)到關，關到位后，電(dian)動(dong)推(tui)桿(gan)Ⅱ再反方向動(dong)作，密(mi)封副夾緊，關閥(fa)結束。開(kai)閥(fa)則反之.

盲(mang)板(ban)(ban)閥(fa)(fa)(fa)(fa)又分(fen)為電動盲(mang)板(ban)(ban)閥(fa)(fa)(fa)(fa)，氣動盲(mang)板(ban)(ban)閥(fa)(fa)(fa)(fa)，液動盲(mang)板(ban)(ban)閥(fa)(fa)(fa)(fa)，敞開式(shi)(shi)插(cha)板(ban)(ban)閥(fa)(fa)(fa)(fa)和(he)封(feng)閉式(shi)(shi)插(cha)板(ban)(ban)閥(fa)(fa)(fa)(fa)。敞開式(shi)(shi)和(he)封(feng)閉式(shi)(shi)插(cha)板(ban)(ban)閥(fa)(fa)(fa)(fa)在之前有詳細的分(fen)析。下面就來詳細的介紹幾種盲(mang)板(ban)(ban)閥(fa)(fa)(fa)(fa)：

（一）F943X電動(dong)(dong)扇(shan)形(xing)盲板(ban)(ban)(ban)閥(fa)(fa)，屬于(yu)自動(dong)(dong)扇(shan)形(xing)盲板(ban)(ban)(ban)閥(fa)(fa)的(de)產品。由夾(jia)緊驅動(dong)(dong)裝置、翻板(ban)(ban)(ban)和閥(fa)(fa)體等部分組成(cheng)。主要用于(yu)工礦行業作為切斷裝置的(de)冶金閥(fa)(fa)門(men)。本閥(fa)(fa)門(men)既可以單臺遠(yuan)距(ju)(ju)離控制，也可以多臺遠(yuan)距(ju)(ju)離控制，也可以在(zai)特(te)殊情況下(xia)進行手動(dong)(dong)操(cao)作。由底座和支撐柱構成(cheng)一個(ge)結構體，具有穩定性高(gao)的(de)特(te)點(dian)；密封(feng)圈在(zai)閥(fa)(fa)板(ban)(ban)(ban)上，具有密封(feng)性能高(gao)的(de)優(you)點(dian)等。

（二）F743X液動(dong)(dong)(dong)扇(shan)形盲(mang)板閥(fa)，主(zhu)要由(you)左(zuo)閥(fa)體(ti)、右(you)閥(fa)體(ti)、絲(si)桿、閘板、密封圈、杠桿、液壓油缸等零(ling)件(jian)組成，并由(you)底座、支撐柱構成一個剛(gang)性結(jie)構體(ti)。閥(fa)門中設有(you)夾(jia)緊(jin)、松(song)開汽缸和翻板汽缸，夾(jia)緊(jin)、松(song)開汽缸通過杠桿和絲(si)桿螺旋驅(qu)動(dong)(dong)(dong)左(zuo)、右(you)閥(fa)體(ti)完成松(song)開、夾(jia)緊(jin)動(dong)(dong)(dong)作，翻板汽缸驅(qu)動(dong)(dong)(dong)閘板完成開關動(dong)(dong)(dong)作。

（三）F643X氣(qi)動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)，是自動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)的一種(zhong)，其(qi)驅(qu)動(dong)(dong)方式為氣(qi)動(dong)(dong)，所以(yi)又名為氣(qi)動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)。F643X氣(qi)動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)又有4種(zhong)閥(fa)(fa)門，F643X-0.5氣(qi)動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)、F643X-1.5氣(qi)動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)、F643X-1.0氣(qi)動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)、F643X-2.0氣(qi)動(dong)(dong)扇(shan)(shan)形(xing)(xing)盲(mang)(mang)(mang)(mang)板(ban)(ban)(ban)閥(fa)(fa)。

（四）F643X氣動扇形盲板閥既可以自動控制又可以遠距離控制的隔斷設備。由左閥體、右閥體、中閥體、連接螺桿（三根）組成。用扳手旋轉連接螺桿，使左右閥體完成夾緊和松開動作，利用閘板上盲板和通孔板的位置變換達到啟閉目的。本閥具有結構簡單，重量輕，性能可靠，操作方便等特點。本閥為短結構系列，橡膠密封圈分別安裝在左、右閥體上。本閥門以其良好的功能被冶金、環保等行業廣泛應用。

（五）F343CX手動扇(shan)形(xing)盲(mang)板(ban)閥(fa)由閥(fa)體(ti)、渦(wo)輪轉(zhuan)動機構(gou)、扇(shan)形(xing)盲(mang)板(ban)等等組成。它的優點是閥(fa)體(ti)固定(ding)(ding)底座上，結構(gou)穩定(ding)(ding)；有盲(mang)板(ban)定(ding)(ding)位塊，可以防止盲(mang)板(ban)漂(piao)移，避(bi)免(mian)密封圈(quan)擦傷；渦(wo)輪轉(zhuan)動機構(gou)，能(neng)松開夾緊閥(fa)體(ti)。
