href="/mqmbfxl.html" class='con_kwd'>盲板隔斷閥</a>，煤氣專用閘閥等<a href="/product/" class='con_kwd'>煤氣閥門</a>于一體的專業(yè)化技術(shù)型企業(yè)，建立之初偉恒人就肩負(fù)著“發(fā)揮技術(shù)優(yōu)勢，幫企業(yè)節(jié)能降耗”的光榮使命。</p><p>淄博偉恒閥門發(fā)起人---賈光明，從1999年就開始了煤氣閥門鉆研，當(dāng)時在對煤氣閥門的研究中發(fā)現(xiàn)，市場上銷售煤氣系統(tǒng)閥門，絕大部分都是普通閥門，沒有針對不同煤氣工況設(shè)計制造，直接導(dǎo)致煤化工，冶金企業(yè)安全事故發(fā)生造成企業(yè)生產(chǎn)維護成本浪費。為了幫助企業(yè)節(jié)能降耗，走訪大量煤氣煙氣行業(yè)用戶而且請教多位閥門權(quán)威，順應(yīng)國際煤氣閥門行業(yè)變化而不停改變，經(jīng)過不斷產(chǎn)品改進，淄博偉恒閥門于2006年4月成立，并定位“煤氣閥門專業(yè)制造商”。</p><p><br/></p><p>閥門安裝的一般要求、最適宜的安裝高度、水平管道上閥門、閥桿方向如下：</p><p>（1）閥門應(yīng)設(shè)在容易接近、便于操作、維修的地方。成排管道（如進出裝置的管道）上的閥門應(yīng)集中布置，并考慮設(shè)置操作平臺及梯子。平行布置管道上的閥門，其中心線應(yīng)盡量取齊。手輪間的凈距不應(yīng)小于10Qmm，為了減少管道間距，可把閥門錯開布置；</p><p>（2）經(jīng)常操作的閥門的安裝位置應(yīng)便于操作，最適宜的安裝高度為距離操作面1．2m上下。當(dāng)閥門手輪中心的高度超過操作面2m時，對于集中布置的閥組或操作頻繁的單獨閥門以及安全閥應(yīng)設(shè)置平臺，對不經(jīng)常操作的單獨閥門也應(yīng)采取適當(dāng)?shù)拇胧ㄈ珂溳?、延伸桿、活動平臺和活動梯子等）。鏈輪的鏈條不應(yīng)妨礙通行。危險介質(zhì)的管道和設(shè)備上的閥門，不得在人的頭部高度范圍內(nèi)安裝，以免碰傷人頭部，或由于閥門泄漏時直接傷害人的面部；</p><p>（3）隔斷設(shè)備用的閥門宜與設(shè)備管口直接相接或靠近設(shè)備。與極度危害、高度危害的有毒介質(zhì)的設(shè)備相連接管道上的閥門，應(yīng)與設(shè)備谷口直接連接，該閥門不得使用鏈輪操縱；</p><p>（4）事故處理閥如消防水用閥、消防蒸汽兩閥等應(yīng)分散布置，且要考慮到事故時的安全操作。這類閥門要布置在控制室后。安全墻后、廠房門外、或與事故發(fā)生處有一定安全距離的地帶；以便發(fā)生火災(zāi)事故時，操作人員可以安全操作；</p><p>（5）除工藝有特殊要求外，塔、反應(yīng)器、立式容器等設(shè)備底部管道上的閥門，不得布置在裙座內(nèi)；</p><p>（6）從干管上引出的水平支管的切斷閥，宜設(shè)在靠近根部的水平管段上；</p><p>（7）升降式止回閥應(yīng)安裝在水平管道上，立式升降式止回閥應(yīng)安裝在管內(nèi)介質(zhì)自下而上流動的垂直管道上。旋啟式止回閥應(yīng)優(yōu)先安裝在水平管道上，也可安裝在管內(nèi)介質(zhì)自下而上流動的垂直管道上；底閥應(yīng)安裝在離心泵吸人管的立管端；為降低泵出口切斷闊的安裝高度，可選用蝶形止回閥；泵出口與所連接管道直徑不一致時，可選用異徑止回閥；</p><p>（8）布置在操作平臺周圍的閥門的手輪中心距操作平臺邊緣不宜大于450mm，當(dāng)閥桿和手輪伸入平臺上方且高度小于2m時，應(yīng)使其不影響操作人員的操作和通行；</p><p>（9）地下管道的閥門應(yīng)設(shè)在管溝內(nèi)或閥井內(nèi)，必要時，應(yīng)設(shè)閥門延伸桿。消防水閥井應(yīng)有明顯的標(biāo)志；</p><p>（10）水平管道上的閥門，閥桿方向可按下列順序確定：垂直向上；水平；向上傾斜45°；向下傾斜45°；不得垂直向下；</p><p>（11）閥桿水平安裝的明桿式閥門，當(dāng)閥門開啟時，閥桿不得影響通行。（淄博偉恒閥門有限公司整理報道）</p><p><br/></p>
