MDD093A-N-030-N2L-110PB0插板閥*電動(dòng)插板閥 電動(dòng)插板閥使用中注意事項(xiàng)及其特點(diǎn)：插板閥的啟閉件是閘板，閘板的運(yùn)動(dòng)方向與流體方向相垂直，插板閥只能作全開(kāi)和全關(guān)，不能作調(diào)節(jié)和節(jié)流。閘板有兩個(gè)密封面，最常用的模式閘板閥的兩個(gè)密封面形成楔形、楔形角隨閥門參數(shù)而異，通常為50，楔式插板閥的閘板可以做成一個(gè)整體，叫做剛性閘板;也可以做成能產(chǎn)生微量變形的閘板,以改善其工藝性，彌補(bǔ)密封面角度在加工過(guò)程中產(chǎn)生的偏差，這種閘板叫做彈性閘板插板閥關(guān)閉時(shí)，密封面可以只依靠介質(zhì)壓力來(lái)密封，即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來(lái)保證密封面的密封，這就是自密封。大部分插板閥是采用強(qiáng)制密封的，即閥門關(guān)閉時(shí)，要依靠外力強(qiáng)行將閘板壓向閥座，以保證密封面的密封性。插板閥密封結(jié)構(gòu)可以分軟密封、硬密封結(jié)構(gòu)[3]。
MDD093A-N-030-N2L-110PB0插板閥*安裝指南 1.安裝前須檢查閥門腔內(nèi)和密封面等部位，不允許有污物或砂粒附著;
2.各連接部位螺栓,要求均勻擰緊;
3.檢查填料部位要求壓緊，既保證填料的密封性，也要保證插板開(kāi)啟靈活;
4.用戶在安裝閥門前，必須校對(duì)閥門型號(hào)，連接尺寸及注意介質(zhì)流向，保證與閥門要求一致性;
5.用戶在安裝閥門時(shí)，必須預(yù)留閥門驅(qū)動(dòng)的必要空間;
6.驅(qū)動(dòng)裝置的接線須按線路圖進(jìn)行;
7.MDD093A-N-030-N2L-110PB0插板閥必須定期保養(yǎng)，不得隨意碰撞及擠壓，以免影響密封。
