Iyini i-ISO 8434-2 futhi ithini inguqulo yakamuva?
Isihloko se-ISO 8434-2 siwukuxhunywa kweshubhu lensimbi lamandla oketshezi kanye nokusetshenziswa okuvamile -
ingxenye 2: 37° izixhumi ezivuthayo.
Uhlelo lokuqala lwakhishwa ngo-1994 futhi lwalungiselelwa IKomidi Lobuchwepheshe ISO/TC 131, amasistimu kagesi we-Fluid, Ikomidi elincane le-SC 4, izixhumi nemikhiqizo nezingxenye ezifanayo.
Inguqulo yamanje evumelekile yi-ISO 8434-2:2007, bona ngezansi kwekhasi lekhava le-ISO 8434-2 ejwayelekile, kanye nesixhumanisi esivela kuwebhusayithi ye-ISO.

I-ISO 8434-2 yavela ku-SAE J514 (eyakhishwa ngo-1950) i-hydraulic tube fitting, ebizwa nge-37 degree flared nezinhlobo ezingenabani, lolu hlobo lwezixhumanisi ezisetshenziswa kakhulu eMelika.
Ikuphi okuqukethwe i-ISO 8434-2 ecacisayo?
I-ISO 8434-2 icacisa izidingo ezijwayelekile nezinobukhulu zokuklama nokusebenza kwezixhumi ezivutha umlilo ezingu-37° ezifanele ukusetshenziswa namashubhu ensimbi anamadayamitha angaphandle asuka ku-6 mm kuya ku-50,8 mm, kuhlanganisa.
Uma ufuna izinto zokwakha ngaphandle kwensimbi, kulungile futhi sicela ubuze isevisi yethu yamakhasimende.
Ingabe Owinile unomkhiqizo ohambisanayo we-ISO 8434-2?
Owinile ashayele lolu hlobo izixhumi njenge-adaptha ye-JIC(Joint Industrial Council ) noma i-adaptha noma isixhumi, futhi zonke lezo zixhumi ezicaciswe ku-ISO 8434-2 ziyatholakala ku-Winner, futhi u-J uvamise ukuhlonza i-JIC engxenyeni., njengokuthi izixhumi zenyunyana eziqondile (1J), isixhumi sendololwane yendololwane (1J9), isixhumi senyunyana ye-T (AJ), isixhumi se-stud esinokuphela kwe-stud ngokuvumelana ne-ISO 6149-3(1JH-N), isixhumi se-bulkhead(6J), isixhumi esishiselayo( 1JW), isigxobo sendololwane esijikayo esine-O-ring(2J9), ……Bheka ishidi lekhathalogi ukuze uthole imininingwane, kukhona uchungechunge olungaphezu kuka-48 olungakhethwa yikhasimende.[Isixhumanisi Sokulanda ikhathalogi]
Ngezansi kunezithombe zesixhumi se-JIC esivuthayo esingu-37°.

Wngaphakathi 37°fIsixhumi se-JIC esilahliwe sihlolwe ngokuvumelana ne-ISO 19879 kanye nokusebenza okuphezulu okudlula i-ISO 8434-2.
Isidingo sokuqeda ku-ISO 8434-2 ukuhlolwa kwesifutho sikasawoti esingama-72 h ngokuhambisana ne-ISO 9227 futhi akukho nokugqwala okubomvu, Izingxenye eziwinile zedlula kude imfuneko ye-ISO 8434-2.
BI-elow iyincazelo ye-ISO kanye nesithombe sokuhlola isifutho sikasawoti Owinile.
