Ivalvu yokuzivalela yegesi yePipeline ekumgangatho ophezulu YX010-003
Eyona nto iphambili kwivalvu yethu yokuzivalela igesi yombhobho zizinto ze-aluminium alloy, eziluphawu lokulawula inkqubo yepayipi yegesi, esetyenziselwa kakhulu ukucima okanye ukulawula ukuhamba kwegesi.
Indawo yokusetyenziswa kwevalvu yokuzivala yegesi yombhobho ikakhulu ikwinkqubo yepayipi yegesi. Ifanelekile ekudlulisweni kwegesi, ukulawulwa koxinzelelo lwegesi kunye nokunikezelwa kwegesi kunye neminye imimandla. Ivalvu yokuzivala yegesi idla ngokufuna ukuba ubushushu bokusebenza bube phakathi kwe--20℃ kunye ne-60℃, kwaye uxinzelelo lokusebenza lube phakathi kwe-0.1MPa kunye ne-10MPa. Kwinkqubo yepayipi yegesi, iivalvu zokuzivala zegesi zisetyenziswa kakhulu kwiinkqubo zokugcina igesi, zothutho kunye nokubonelela ngegesi ezifana negesi, igesi yendalo kunye negesi yepetroliyam enyibilikisiweyo.
Ivalvu yokuzivala ngegesi yombhobho inesantya sokuvula nokuvala esikhawulezayo, esinokuyinqumla ngokukhawuleza indlela igesi ephuma ngayo. Le yeyona nto ibalulekileyo ekugcineni inkqubo ikhuselekile xa kukho imeko engxamisekileyo. Okwesibini, ukusebenza kakuhle kokutywinwa kwevalvu yokuzivala ngegesi, nto leyo enokuqinisekisa ukuba igesi ayivuzi kwaye ikhusele okusingqongileyo kunye nokhuseleko lomntu. Kwangaxeshanye, ivalvu inokumelana okuphantsi kwaye ayibangeli ukulahleka koxinzelelo lwenkqubo.
Ivalvu yokuzivala ngegesi yombhobho idlala indima ebalulekileyo kwinkqubo yepayipi yegesi, kwaye iingenelo zayo ezinje ngokuvula nokuvala ngokukhawuleza, ukusebenza kakuhle kokutywina kunye nokufakelwa okulula kuyenza ibe sisixhobo esibalulekileyo sokuqinisekisa ukhuseleko kunye nokusebenza okuqhelekileyo kwenkqubo yegesi.
