Yini Okufanele Ifakwe I-Valve RFQ?
Isicelo se-valve esiwusizo sekhotheshini (I-RFQ) utshela umphakeli lapho i-valve izosetshenziswa khona, okufanele ixhumeke kukho, futhi yiziphi izincwadi ezidingwa yiphrojekthi. Qala ngesicelo kanye nemakethe yendawo. Bese ucacisa umsebenzi we-valve, ubungako, ukuxhumana emikhawulweni yomibili, izinto zokwakha, uketshezi, izimo zokusebenza, izimvume ezidingekayo, ubuningi nendawo yokulethwa.
Uma ungalazi inani lobuchwepheshe, bhala "kuzoqinisekiswa" futhi unamathisele noma yimuphi umdwebo otholakalayo noma imininingwane yephrojekthi. Ukuqagela kungaholela ekhotheshini yevalvu engahambisani nokufakwa.
Isicelo se-“valve engu-3/4-intshi” iyodwa akwanele ukuqinisekisa ukuthi umkhiqizo ohlongozwayo ulingana nepayipi, imitha yamanzi noma indawo evalekile. Izixhumanisi zokugcina, izilinganiso ezisebenzayo nezibalulekile kufanele zihlolwe ngokumelene nemodeli ngqo.
Ikopisheka Uhlu Lokuhlola Lwe-RFQ Yevalvu Yezinkundla Ezingu-18
Ngombuzo wokuqala, izinkambu eziphelele 1–4, 6–8, 10-12 futhi 15. Izinkambu ezisele zingokuzithandela ekuxhumaneni kwakho kokuqala, nakuba zingadingeka ngaphambi kokukhethwa komkhiqizo wokugcina noma ikhotheshini.

Ukuze uthole inkomba ebanzi yobuchwepheshe, i Uhlu lokuhlola olucacisayo lweValve Manufacturers Association ihlanganisa izimo zesevisi, qeda ukuxhumana, izinto zokwakha, ukuhlolwa kanye nemibhalo. Sebenzisa izidingo zephrojekthi yakho ukuze unqume ukuthi yiziphi izinkambu ezisebenzayo.
Lezi zinkambu zisiza umphakeli ukuthi abuyekeze isicelo sakho; azithathi indawo yokucaciswa kokugcina kukanjiniyela wephrojekthi. Ezinye izinkambu ngeke zisebenze kuwo wonke ama-valve. Ngokwesibonelo, Idatha ye-Cv/Kv ingase ibaluleke ku-valve yokulinganisa kodwa ingase ingabi imfuneko yokuqala ye-valve elula yokuhlukanisa..
Izithombe zisiza ukuchaza ingxenye noma isiphetho. Umdwebo wamanje kanye nokucaciswa kwezinto ezibonakalayo kusungula imfuneko eqondile.
Uma uthole ikhandidethi ku Amakhasi omkhiqizo we-BMAG Valve, kopisha igama layo lemodeli kanye ne-URL yekhasi endaweni 5. Izithombe zomkhiqizo kanye nekhathalogi evamile kusiza ukuhlonza ikhandidethi, kodwa cela umdwebo wamanje we imodeli ngqo kanye nosayizi ngaphambi kokuqinisekisa ukufaneleka. Uma ushintsha i-valve efakiwe, namathisela isithombe, umdwebo noma inombolo yengxenye ekhona.
Inani elincane le-oda liyahluka ngomkhiqizo. Isikhathi sokuhola sokukhiqiza esijwayelekile cishe 30- izinsuku ezingama-45, ngaphansi komkhiqizo okhethiwe, ubuningi nokuqinisekiswa kwe-oda. Buza ithimba labadayisi mayelana namasampuli kanye ne-MOQ esebenzayo yesicelo sakho.
Izikhala Ezine Ezibangela Imibuzo Ephindaphindiwe Yezobuchwepheshe
1. Usayizi unikiwe, kodwa uxhumano lokukhwelana alukho
Rekhoda i-inlet ne-outlet uxhumano ngokuhlukana. Faka nezinga lokuxhuma, usayizi kanye nesitayela sokugcina. Uma ivalvu kufanele ilingane nemitha ekhona, ukuhlanganiswa kwepayipi noma indawo ebiyelwe, hlinzeka ngomdwebo onobukhulu kanye nanoma yimiphi imikhawulo yemvume yokufaka. Usayizi wegama awusunguli bonke ubukhulu bokulingana.
Uma ukhomba i-valve ekhona emakhakheni omzimba wayo, sebenzisa yethu umhlahlandlela wokuqonda izimpawu zamavalvu ngaphambi kokuqeda izinkambu 6–7. Qinisekisa izinga lokuxhuma ekugcineni nobukhulu ngokuhlukene nomdwebo noma ukulinganisa.
Isithombe sokugcina sisiza ukukhombisa isitayela, kodwa ayikwazi ukuqinisekisa izinga lomucu noma ukulingana ngaphandle komdwebo noma isilinganiso.
Yisho indinganiso yochungechunge esebenzayo ku-RFQ. Ngokwesibonelo, khomba I-ASME B1.20.1 lapho iphrojekthi icacisa i-NPT, noma Umsunguli wethu uMnu.James waziqalela esakhe isifutha sebhizinisi ngemuva kokusebenza isikhathi eside kulo mkhakha 228-1 uma icacisa intambo yepayipi ehambisanayo kulelo zinga.
