【閥門概述】：
上海明保閥生產(chǎn)的【Q347固定球閥】的大樞軸結(jié)構(gòu)保證在高壓下準(zhǔn)確的球體中心位置，保證了閥門良好的操作性能；標(biāo)準(zhǔn)閥座采用彈簧結(jié)構(gòu)，將閥座推向球體，保證了良好的進(jìn)出口雙向密封性能；利用自帶的排放閥，閥體中腔可向外排放；樞軸采用防吹出保護(hù)結(jié)構(gòu)，有效地防止泄漏。
【閥門用途及特點(diǎn)】：
【Q347固定球閥】適用于：化工、石油、天然氣、冶金、等行業(yè)及含硫化氫介質(zhì)、雜質(zhì)多、腐蝕嚴(yán)重的天然氣長(zhǎng)輸管線。
1、低磨擦系數(shù)的軸承，使得扭矩減少到最小，便于閥門啟閉。
2、閥桿與閥體有效的接觸，使防靜電接地裝置性能優(yōu)越等。
3、具有性能優(yōu)異，可靠性高，用途廣泛，價(jià)格合理等優(yōu)點(diǎn)。
