Z41H美標(biāo)法蘭閘閥特點(diǎn)
Z41H美標(biāo)法蘭閘閥流體阻力小，適用的壓力、溫度范圍大，介質(zhì)流動(dòng)方向不受限制，密封性能良好。
Z41H美標(biāo)法蘭閘閥安裝要點(diǎn)
1）、安裝位置、高度、進(jìn)出口方向必須符合設(shè)計(jì)要求，連接應(yīng)牢固緊密。
2）、安裝在保溫管道上的各類手動(dòng)閥門，手柄均不得向下。
3）、閥門安裝前必須進(jìn)行外觀檢查，閥門的銘牌應(yīng)符合現(xiàn)行國(guó)家標(biāo)準(zhǔn)《通用閥門標(biāo)志》GB 12220的規(guī)定。對(duì)于工作壓力大于1.0 MPa 及在主干管上起到切斷作用的閥門，安裝前應(yīng)進(jìn)行強(qiáng)度和嚴(yán)密性能試驗(yàn)，合格后方準(zhǔn)使用。強(qiáng)度試驗(yàn)時(shí)，試驗(yàn)壓力為公稱壓力的1.5倍，持續(xù)時(shí)間不少于5min，閥門殼體、填料應(yīng)無(wú)滲漏為合格。嚴(yán)密性試驗(yàn)時(shí)，試驗(yàn)壓力為公稱壓力的1.1倍；試驗(yàn)壓力在試驗(yàn)持續(xù)的時(shí)間應(yīng)符合GB 50243標(biāo)準(zhǔn)要求，以閥瓣密封面無(wú)滲漏為合格。
