style="text-indent:25px">閥座是閥門內(nèi)可拆卸面部件，用于支撐閥芯全關(guān)位置，并構(gòu)成密封副。它可將閥座前管路較高的液體壓力減少至閥座后管路所需的水平。這里的傳輸介質(zhì)主要是水。閥座普遍用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場合，以保證給水系統(tǒng)中各用水點獲得適當(dāng)?shù)姆?wù)水壓和流量。鑒于水的漏失率和浪費程度幾乎同給水系統(tǒng)的水壓大小成正比，因此閥座具有改善系統(tǒng)運行工況和潛在節(jié)水作用，據(jù)統(tǒng)計其節(jié)水效果約為30%。閥座的構(gòu)造類型很多，以往常見的有薄膜式、內(nèi)彈簧活塞式等。閥座的基本作用原理是靠閥座內(nèi)流道對水流的局部阻力降低水壓，水壓降的范圍由連接閥座瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動調(diào)節(jié)。福州閥球閥座檢修</p><p
