氧氣專用截止�-JY41氧氣專用截止�是根�(jù)氧氣管網(wǎng)�(yùn)行特�(diǎn)以及考慮氧氣介質(zhì)的易燃易爆的特性,以安全可靠和性能�(yōu)越為�(shè)�(jì)原則,并參照中華人民共和國冶金工�(yè)部制定的《氧氣安全規(guī)程》的�(guī)定而設(shè)�(jì)、制造的確保氧氣管網(wǎng)安全�(yùn)行的專用閥門。主體材料選用不銹鋼或阻燃性極好的銅合�,密封面為本體或堆焊D802,其余內(nèi)件采用不銹鋼或銅合金;傳動部位的潤滑采用不可燃的潤滑�,并�(biāo)有明顯的禁油�(biāo)�。在�(jié)�(gòu)�,支架采用全閉封,并有導(dǎo)除靜電裝�,閥桿上配有防塵��
氧氣專用截止�-JY41氧氣專用截止��(jié)�(gòu)特點(diǎn)
1、對于公稱壓力PN≥1.6MPa、DNl25�200采用�(nèi)旁通結(jié)�(gòu);DN250�500采用帶外旁通閥�(jié)�(gòu)。其目的是減小閥�、閥后的壓力差以避免高流速、高沖刷以及防止�(chǎn)生高�,從而保證了氧氣管網(wǎng)的安全運(yùn)�,同�(shí)也減小了操作力矩�
2、介�(zhì)流向:PN≥1.6MPa、DN≤100介質(zhì)由閥瓣下方流入閥瓣上�(即低�(jìn)高出),DN≥125介質(zhì)由閥瓣卜方流入下�(高�(jìn)低出)o對于DN≥125的閥門采用介質(zhì)高�(jìn)低出的流向,一方面足內(nèi)旁通閥�(jié)�(gòu)上的需�,另一方面由于介質(zhì)壓力的作用使閥門的關(guān)閉力大大減小�
3、該閥設(shè)有導(dǎo)靜電安全裝置,可避免因靜電產(chǎn)生火花�
4、與普通截止閥相比,氧氣管路用截止閥的支架部分采用全封閉式�(jié)�(gòu),且壓緊填料�(shí)可以打開支架上的防護(hù)蓋板,起到了防油防塵的作�。并有明顯的禁油�(biāo)��
5、全部零件采用嚴(yán)格的脫脂處理�
