style="font-size:16px;">固定球閥的優(yōu)勢(shì)1、密封緊急注脂救護(hù)：由于介質(zhì)中的異物或火災(zāi)造成閥座密封意外失效，注脂閥提供了與注脂的快速連接，方便快捷地將密封脂注入到閥座密封部位，緩解泄漏。2、可靠的閥桿密封和低操作力矩：除了設(shè)置標(biāo)準(zhǔn)密封套圈外，填料壓蓋上也設(shè)置了“O”型密封圈，雙重密封保證了閥桿密封的可靠性；增設(shè)的石墨填料和密封脂注入使火災(zāi)后的閥桿泄漏降至比較低。閥桿滑動(dòng)軸承和止推軸承使閥門(mén)操作輕便。3、全通徑或縮徑：可根據(jù)需要選用全通徑或縮徑結(jié)構(gòu)。全通徑閥門(mén)流量孔徑與管線內(nèi)徑一致，便于管線清掃。4、閥桿可加長(zhǎng)：根據(jù)安裝或操作的需要，可對(duì)閥門(mén)閥桿進(jìn)行加長(zhǎng)。加長(zhǎng)桿球閥，特別適用于城市煤氣等需要埋地鋪設(shè)管線的場(chǎng)合。加長(zhǎng)閥桿尺寸按客戶需要確定。5、操作靈活：采用具有小摩擦系數(shù)和良好自潤(rùn)滑性的閥座和閥桿軸承，**地減少了閥門(mén)的操作扭矩。因此即使在沒(méi)有提供密封潤(rùn)滑脂的情形下，也能夠長(zhǎng)期靈活自如地對(duì)閥門(mén)進(jìn)行操作。</span>
