Ivalve yokhuseleko lwerhasi yendalo enyibilikisiweyo ibhekiselele kwinkqubo yobushushu obuphantsi be-LNG yegesi yendalo engamanzi. Amacandelo okuvula kunye nokuvala ngokuqhelekileyo avaliwe phantsi kwesenzo samandla angaphandle. Xa uxinzelelo oluphantsi lobushushu be-LNG lunyibilikisiwe lwegesi yendalo kwisixhobo sobushushu obuphantsi okanye umbhobho onyuka ngaphezu kwexabiso elichaziweyo, liya kudlula kwinkqubo Iivalvu ezikhupha i-LNG kunye negesi yendalo enyibilikisiweyo ngaphandle ukuthintela uxinzelelo oluphakathi kumbhobho we-cryogenic okanye izixhobo ezingaphezulu kwexabiso elichaziweyo. Ukulawula ubushushu obuphantsi be-LNG yegesi yendalo engamanzi ukuba ingagqithi kwixabiso elichaziweyo idlala indima ebalulekileyo ekukhuseleni ukhuseleko lomntu kunye nokusebenza kwezixhobo.
Iimpawu zesakhiwo:
1. Ivalve yokhuseleko lobushushu obuphantsi iye yafumana unyango olusezantsi lwe-cryogenic kwaye inokumelana namaqondo obushushu aphantsi -196℃.
2. I-disc ye-valve ye-valve ephantsi yobushushu obuphantsi i-chrome-plated okanye i-nitrided ukuphucula ukuqina komphezulu we-valve stem kunye nokuphucula ukuthembeka kwesitywina sokupakisha.
3. I-Gaskets ye-valve yokhuseleko oluphantsi lobushushu inokutywinwa okuthembekileyo kunye nokubuyiselwa kwiqondo lokushisa, iimeko ezisezantsi kunye nokutshintsha kweqondo lokushisa.
4. Ukuqalisa kwamahhala, ukutywinwa okuthembekileyo, uxinzelelo oluzinzileyo lokuthatha uhambo, njl.
5. Ukuphakama kokuvula kungaphezulu kwe-1/4 ububanzi bomqala, kwaye umthamo wokukhupha ukhulu.
6. I-valve yokukhusela ene-wrench ingavulwa ngesandla nge-wrench xa uxinzelelo oluphakathi lufikelela ngaphezu kwe-75% yoxinzelelo lokuvula.
7. Kukho iindlela ezininzi zokudibanisa intambo, i-flange kunye ne-welding, kwaye umbhobho we-welding uyahlukana kwaye kulula ukuyifaka nokugcina.
