安全閥的反作用力是可以計(jì)算的。四、調(diào)節(jié)閥的安裝（1）調(diào)節(jié)閥的安裝位置應(yīng)滿足管道系統(tǒng)（工藝流程）設(shè)計(jì)要求，并應(yīng)盡量靠近與其相關(guān)的就地指示儀表（一次表），盡量接近測量元件所在位置，以便于在手動操作旁通閥時(shí)，能觀察到一次儀表數(shù)值。調(diào)節(jié)閥應(yīng)盡量正立垂直安裝于水平管道上，特殊情況下才可水平或傾斜安裝，但須加支撐。（2）為便于操作和維修，減少占地，調(diào)節(jié)閥組應(yīng)盡量布置在地面靠墻、靠設(shè)備或平臺等易于接近的地方。與平臺或地面的凈空應(yīng)不小于250mm。（3）調(diào)節(jié)閥應(yīng)安裝在環(huán)境溫度不高于60℃且不低于-40℃的場所，應(yīng)遠(yuǎn)離振動器，盡量避免火災(zāi)危險(xiǎn)的影響。（4）調(diào)節(jié)閥一般都要安裝旁路與旁通閥。旁通閥主要是當(dāng)調(diào)節(jié)檢修停用時(shí)作調(diào)節(jié)流量之用，故一般應(yīng)選用截止閥。但當(dāng)旁通閥DN≥l5Omm時(shí)，也可選用閘閥。調(diào)節(jié)前后的切斷閥宜先用閘閥，因其阻力小，關(guān)閉嚴(yán)密。一般調(diào)節(jié)閥前后有大小頭，應(yīng)緊接調(diào)節(jié)閥安裝。為了在調(diào)節(jié)閥檢修時(shí)將兩切斷閥之間管道泄壓、排凈，一般可在調(diào)節(jié)閥入口側(cè)上游的切斷閥之間的管道的比較低點(diǎn)設(shè)排液閥DN＝15mm。另外，宜在入口切斷閥后、調(diào)節(jié)閥前加設(shè)過濾器（調(diào)節(jié)閥DN＜25mm者，必須加過濾器）。</p><p> 3、電磁換向閥利用電磁鐵的通電吸合與斷電釋放而直接推動閥芯來控制液流方向。它是電氣系統(tǒng)和液壓系統(tǒng)之間的信號轉(zhuǎn)換元件。電磁換向閥是利用電磁鐵吸力推動閥芯來改變閥的工作位置。因?yàn)樗梢钥刂菩盘柊l(fā)送到一個(gè)按鈕開關(guān)，行程開關(guān)，限位開關(guān)，壓力繼電器，使用操作簡單，易于實(shí)現(xiàn)自動化，所以***應(yīng)用。電磁換向閥的作用是它可以改變控制液流的方向，從而改變液動換向閥的位置。由于操縱液動換向閥的液壓推力可以很大，所以主閥可以做得很大，允許有較大的流量通過。這樣用較小的電磁鐵就能控制較大的液流。電磁換向閥工作原理是，通過電磁鐵控制滑閥閥芯的不同位置，以改變形油液的流動方向。變換閥心在閥體內(nèi)的相對工作位置，使閥體各油口連通或斷開，從而控制液壓執(zhí)行元件（如液壓桿、液壓馬達(dá)）的換向或啟停。當(dāng)電磁鐵斷電時(shí)，滑閥由彈簧保持在中間位置或初始位置（脈沖式閥除外）。若推動故障檢查按鈕可使滑閥閥芯移動。4、其它閥門按閥的工作位置分類閥的工作位置稱為“位”，有幾個(gè)切換工作位置的閥就稱為“幾位”閥。經(jīng)常使用的有“二位”閥和“三位”閥。閥在未加控制信號或**作時(shí)所處的位置稱為零位。按閥的接口數(shù)目分類閥的接口（包括排氣口）稱為“通”。信號溝槽閘閥常應(yīng)用于自動噴水消防管理系統(tǒng)，來監(jiān)控供水管路，可以再遠(yuǎn)處指示閥門開度。</p><div

許多閥門具有方向性<br/> 如截止閥、節(jié)流閥、減壓閥、止回閥等，如果裝倒裝反，就會影響使用效果與壽命（如節(jié)流閥），或者根本不起作用（如減壓閥），甚至造成危險(xiǎn)（如止回閥）。一般閥門，在閥體上有方向標(biāo)志。萬一沒有，應(yīng)根據(jù)閥門工作原理，正確識別。<br/> 截止閥的閥腔左右不對稱，流體要讓其由下而上通過閥口，這樣流體阻力小（由形狀所決定），開啟省力（因介質(zhì)壓力向上），關(guān)閉后介質(zhì)不壓填料，便于檢修，這就是截止閥為什么不可安反的道理。其它閥門也有各自的特性。<br/> 閥門安裝位置，必須方便于操作<br/> 即使安裝暫時(shí)困難些，也要為操作人員的長期工作著想。較好閥門手輪與胸口取齊（一般離操作地坪1.2米），這樣，開閉閥門比較省勁。落地閥門手輪要朝上，不要傾斜，以免操作別扭?？繅C(jī)靠設(shè)備的閥門，也要留出操作人員站立余地。<br/> 要避免仰天操作，尤其是酸堿、有害介質(zhì)等，否則很不安全。<br/> 龍子湖區(qū)上五閥門供應(yīng)</p><p
