Izici zesakhiwo se-valve yokuphepha yegesi yemvelo enoketshezi

I-valve yokuphepha yegesi yemvelo ewuketshezi isho isistimu yegesi yemvelo enezinga lokushisa ephansi ye-LNG. Izingxenye zokuvula nokuvala ngokuvamile zivaliwe ngaphansi kwesenzo samandla angaphandle. Lapho ingcindezi ye-LNG enezinga lokushisa eliphansi legesi yemvelo ewuketshezi emshinini wezinga lokushisa eliphansi noma ipayipi ikhuphuka ngaphezu kwevelu eshiwo, izodlulela ohlelweni Amavalvu akhipha i-LNG negesi yemvelo ewuketshezi ngaphandle ukuze kuvinjelwe ukucindezela kwendawo ephakathi epayipini le-cryogenic noma amathuluzi ukuthi adlule inani elishiwo. Ukulawula izinga lokushisa eliphansi legesi yemvelo eyenziwe uketshezi lwe-LNG ukuthi ingeqi inani elishiwo kudlala indima ebalulekile ekuvikeleni ukuphepha komuntu siqu nokusebenza kwemishini.

Izici zesakhiwo:

1. I-valve yokuphepha yezinga lokushisa eliphansi ithole ukwelashwa okunezinga lokushisa eliphansi le-cryogenic futhi ingamelana nezinga lokushisa eliphansi elingu -196℃.

2. I-disc ye-valve yokuphepha yezinga eliphansi lokushisa i-chrome-plated noma i-nitrided ukuze kuthuthukiswe ubulukhuni bobuso besiqu se-valve futhi ithuthukise ukuthembeka kophawu lokupakisha.

3. Ama-gaskets ama-valve okuphepha asezingeni eliphansi anokubekwa uphawu okuthembekile nokubuyiselwa endaweni yokushisa yasekamelweni, izimo zokushisa eziphansi kanye nokushintsha kwezinga lokushisa.

4. Ukuqalisa kwamahhala, ukubekwa uphawu okuthembekile, ukucindezela okuzinzile kokusuka, njll.

5. Ukuphakama kokuvula kungaphezu kwe-1/4 ububanzi bomphimbo, futhi ivolumu yokukhipha inkulu.

6. I-valve yokuphepha ene-wrench ingavulwa ngesandla nge-wrench lapho ukucindezela okuphakathi kufinyelela ngaphezu kwe-75% yokucindezela kokuvula.

7. Kunezindlela eziningi zokuxhuma zentambo, i-flange kanye ne-welding, futhi ipayipi yokushisela iyahlukaniseka futhi kulula ukuyifaka nokuyigcina.
