同時增加了兩個優(yōu)點(diǎn)：密封更合理、兼有截止功能。供熱工程中在熱力站二次網(wǎng)上使用，具有優(yōu)異的流量調(diào)節(jié)特性，特別適用于變流量系統(tǒng)。8、自力式平衡閥自力式平衡閥也叫流量控制閥。工作原理：在閥門內(nèi)有一個由彈簧與橡膠膜組成的機(jī)構(gòu)，它與閥桿連接。如果流量增大，會在其上產(chǎn)生一個不平衡力，使得閥瓣向關(guān)閉方向移動，以減少過流面積，降低流量，使流量回歸設(shè)定值。反之亦然。由此始終保持閥后流量不變，達(dá)到控制流量的目的。安裝在供熱系統(tǒng)的熱人口，分支點(diǎn)。自動消除水力失調(diào)，提高系統(tǒng)效能，實(shí)現(xiàn)經(jīng)濟(jì)運(yùn)行。自力式平衡閥有方向性，切勿裝反。9、安全閥當(dāng)介質(zhì)壓力超過規(guī)定數(shù)值時，閥門能自動開啟并泄壓，當(dāng)壓力正常后，又能自動閉合，以保證系統(tǒng)正常運(yùn)行，起這種作用的閥門叫安全閥。按結(jié)構(gòu)分有：彈簧式、杠桿式、脈沖式。按動作量分：閥瓣開啟高度與閥座通徑之比10%以下叫微啟式，20%-30%叫全啟式。按排泄方式分：介質(zhì)通過管道排走叫封閉式，直接排向空中叫敞開式。現(xiàn)以彈簧式為例作一簡述：彈簧力與介質(zhì)作用于閥瓣的正常壓力相平衡，使密封面閉合；當(dāng)介質(zhì)壓力過高時，彈簧受到壓縮，閥板開啟，介質(zhì)從中泄出；當(dāng)壓力回降到正常值時，彈簧力又將閥門關(guān)閉。上海電動閥門直銷</p><p
