Ngomkhiqizo we-NSEN phumelela ukuhlolwa kofakazi njengokujwayelekile BS 6364:1984 by TUV.I-NSEN iyaqhubeka nokuletha inqwaba ye-valve butterfly evala izinhlangothi ezimbili.

I-valve ye-Cryogenic isetshenziswa kabanzi embonini ye-LNG.Ngoba abantu banaka kakhulu izindaba zemvelo, i-LNG, lolu hlobo lwamandla ahlanzekile luyathandwa.

Njengoba izinga lokushisa le-LNG ngaphansi kwengcindezi evamile lingu-162 ℃, futhi linezici zokuvutha nokuqhuma, i-valve yokushisa ye-cryogenic ayihlangabezani kuphela nezidingo zokushisa okuphansi kokusetshenziswa kwezinga lokushisa, kodwa futhi idinga ukucabangela umklamo wokuvikela umlilo.Kungenxa yalezi zidingo ukuthi ukuphepha nokuthembeka kwamavalve e-cryogenic kuzoba phezulu kunama-valve ajwayelekile.

Okubaluleke nakakhulu, umzimba we-valve, ipuleti levemvane, ingxenye yesandiso kanye nezingxenye zangaphakathi kufanele zicutshungulwe ngendlela ekhaliphile ngaphambi kokuqeda ukuze kuqedwe ithonya lokushintsha kwesigaba.Uma kungenjalo, ukuguqulwa kwesigaba se-martensite kuzokwenzeka emazingeni okushisa aphansi, okubangela ukuguqulwa kwe-valve, okuholela ekutheni I-valve ivuze.

Uhlobo lokuxhuma lwalokhu kuthunyelwa luyi-flange ne-wafer, futhi impahla yomzimba we-valve nediski yi-CF8M.Impahla yokuvala iseyiyo yonke idizayini yensimbi eqinile yokuvala, ene-low emission packing stem sealing.

Uma uthemba ukufunda okwengeziwe noma ukuthola isixazululo sephrojekthi yakho, wamukelekile ukuthintana nathi.
