Yintoni i-ISO 8434-3 kwaye yeyiphi inguqulelo yamva nje?
Isihloko se-ISO 8434-3 ludibaniso lwetyhubhu yesinyithi yamandla olwelo kunye nokusetyenziswa ngokubanzi -
inxalenye 3: O-ring ubuso izihlanganisi itywina.
Ushicilelo lokuqala lukhutshwe kwi-1995 kwaye lulungiswe yiKomiti yezoBugcisa ISO/TC 131, iinkqubo zamandla e-Fluid, i-Subcommittee SC 4, izixhumi kunye neemveliso ezifanayo kunye namacandelo.
Inguqulelo esebenzayo yangoku yi-ISO 8434-3:2005, jonga ngezantsi kwephepha le-cover ye-ISO 8434-3 esemgangathweni, kunye nekhonkco kwiwebhusayithi ye-ISO.

I-ISO 8434-3 yavela kwi-SAE J1453 (eyakhutshwa ngo-1987) Fitting--O-ring face seal, ebizwa ngokuba yi-ORFS fitting, olu hlobo lwezihlanganisi lusetyenziswa kakhulu eMelika.
Ngowuphi umxholo ocaciswa yi-ISO 8434-3?
I-ISO 8434-3 ichaza iimfuno ngokubanzi kunye nobukhulu boyilo kunye nokusebenza kwe-O-ring izihlanganisi zetywina zobuso ezenziwe ngentsimbi yetyhubhu engaphandle kweedayamitha okanye ithumbu ngaphakathi kwedayamitha ye-6 mm ukuya kwi-38 mm, kubandakanywa.
Ukuba ufuna izinto ngaphandle kwentsimbi, kulungile kwaye nceda ubuze inkonzo yethu yabathengi.
Ngaba ophumeleleyo unemveliso ehambelanayo ye-ISO 8434-3?
Ophumeleleyo ufowunele olu hlobo lwezihlanganisi njenge-ORFS(O-ring face seal ) iadaptha okanye iadaptha okanye isidibanisi, kwaye zonke ezo ziqhagamsheli ezichazwe kwi-ISO 8434-3 ziyafumaneka kuMphumeleli, kwaye u-F uqhelekile ukuchonga i-ORFS ekupheleni kwenxalenye., njengezihlanganisi ezithe tye zomanyano (1F), isidibanisi somanyano lwengqiniba (1F9), isidibanisi somanyano lwe-T (AF), isidibanisi se-stud esinesiphelo se-stud ngokungqinelana ne-ISO 6149-2(1FH-N), isidibanisi se-bulkhead (6F), i-elbow swivel stud nge-O-ring(2F9), ……Jonga iphepha lekhathalogu ngeenkcukacha, kukho ngaphezu kwama-33 uluhlu olunokukhethwa ngumthengi.[Ikhonkco lokuKhuphela uluhlu]
Apha ngezantsi kukho imifanekiso eqhelekileyo ye-O-ring yobuso betywina ye-ORFS.

Ophumeleleyo i-O-ring face seal ORFS isinxibelelanisi esivavanyiwe ngokuhambelana ne-ISO 19879 kunye nokusebenza okuphezulu okugqitha i-ISO 8434-3.
Imfuno yokugqiba kwi-ISO 8434-3 yi-72 h engathathi hlangothi yokuvavanya ityuwa-isitshizi ngokuhambelana ne-ISO 9227 kwaye akukho mhlwa obomvu, iindawo eziphumeleleyo zigqithise kakhulu imfuneko ye-ISO 8434-3.
Apha ngezantsi kukho ukucaciswa kwe-ISO kunye nomfanekiso wokuvavanya ityuwa yokutshiza.
