style="text-indent:25px">閥芯是一種自動(dòng)降低管路工作壓力的專門裝置，它可將閥前管路較高的液體壓力減少至閥后管路所需的水平。這里的傳輸介質(zhì)主要是水。閥芯普遍用于高層建筑、城市給水管網(wǎng)水壓過(guò)高的區(qū)域、礦井及其他場(chǎng)合，以保證給水系統(tǒng)中各用水點(diǎn)獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費(fèi)程度幾乎同給水系統(tǒng)的水壓大小成正比，因此閥芯具有改善系統(tǒng)運(yùn)行工況和潛在節(jié)水作用，據(jù)統(tǒng)計(jì)其節(jié)水效果約為30%。閥芯的構(gòu)造類型很多，以往常見(jiàn)的有薄膜式、內(nèi)彈簧活塞式等。閥芯的基本作用原理是靠閥內(nèi)流道對(duì)水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動(dòng)調(diào)節(jié)。福建小流量閥的閥芯減壓閥中的閥芯是實(shí)現(xiàn)控制壓力的主要零部件之一。</p><div
