Uchungechunge lwe-DBB2: I-Bolted Bolted Double Block enkulu enebhondi namavalvu Opha
AMAKHATHALOGU
I-Hikelok Block kanye ne-Bleed Valves
IsingenisoInhlanganisela eyingqayizivele ye-Hikelok yama-block aphindwe kabili nama-valve esistimu yokopha inika amandla ukushintshwa okushelelayo kusuka ohlelweni lwamapayipi ukuya ku-instrumentation, ihlinzeka ngamaphoyinti okuvuza amancane, isisindo esifakiwe esiphansi, kanye nemvilophu yesikhala esincane. Ama-block and Bleed Valves aklanyelwe ukucubungula izindawo zokuhlukanisa amapayipi, ukukhweza okuqondile kumathuluzi, ukuhlanganisa amathuluzi okuvala, ukuvinjwa okuphindwe kabili kanye nokuhlukaniswa kwegazi, ama-vents nama-drain.
IziciUbukhulu bengcindezi yokusebenza bufika ku-10000 psig (689 bar)Izinga lokushisa lokusebenza kusuka -10 ℉ kuya ku-1200 ℉ (-23 ℃ kuya ku-649 ℃)Ukugcwalisa uhla olukhona lwesiqephu esisodwa, i-flange kuya ku-flange ama-valve e-DBB wokwakha afakwe ngomshudo atholakala ngosayizi ukusuka ku-1/2 ukuya ku-2Yakhelwe ngokuvumelana ne-ASME VIII & ANSI B16.34Isisindo, indawo nokonga izindleko ngaphezu kwemiklamo yendabukoUkulandeleka okuphelele kwezinto
IzinzuzoIsisindo, indawo nokonga izindleko ngaphezu kwemiklamo yendabukoI-stem seal elayishwe bukhoma iqinisekisa ukuvaleka kahle kuyo yonke ingcindezi nebanga lokushisa. Isiqu esihlanganiswe ngaphakathi sivikela ekuqhumeni.Umklamo we-AntistaticIzitifiketi zekhemikhali nezomzimba ziyatholakalaIzihlalo ezilayishwe bukhoma zigcina uphawu lwesistimu ngokushintsha kwengcindezi nezinga lokushisaUkukhululeka kwengcindezi ye-Cavity kuvimbela ukucindezela ngokweqile ekukhuleni okushisayo kwemidiya yesistimu lapho i-valve ivaliweUkukhishwa kwekhabhoni encishisiwe
