- 軟密封法蘭球閥 產(chǎn)品特點(diǎn)1、*的閥座:聚多年球閥制造經(jīng)驗(yàn)而設(shè)計(jì)的閥座,確保閥門密封,磨擦系數(shù)低,操作力矩小、多種閥座材料、適應(yīng)范圍廣。
2、開關(guān)無誤的手柄:采用扁頭閥桿,與手柄的連接不會(huì)錯(cuò)位,從而保證手柄指示的開關(guān)狀態(tài)與閥一致辭。
3、鎖緊裝置:為防止閥門開關(guān)誤操作,在閥門全開、全關(guān)位置有鎖定孔,確保閥門處于正確的位置。
4、閥桿防飛結(jié)構(gòu):閥桿為下裝式,防止受壓飛出,同時(shí)可在火災(zāi)后,與閥體形成金屬接觸,確保閥桿密封。軟密封法蘭球閥 性能規(guī)范設(shè)計(jì)依據(jù)國標(biāo)系列美標(biāo)系列設(shè)計(jì)標(biāo)準(zhǔn)GB/T12237AP16DANSI B16.34法蘭連接結(jié)構(gòu)長(zhǎng)度GB/T12221AP16DANSI B16.10結(jié)構(gòu)長(zhǎng)度(焊接)GB/T15188.1AP16DANSI B16.10連接法蘭GB/T9113
