Umgaqo wokukhetha
(1) Ukhuseleko kunye nokuthembeka. I-Petrochemical, isikhululo soMbane, i-MetalAllgergy kunye nezinye iimfuno zemveliso yemveliso yenkqubo eqhubekayo, izinzile, yokuhamba. Ke ngoko, i-valve ifuneka ithembeke kakhulu, into enkulu yokhuseleko, ayinakubangela ukhuseleko olukhulu lwemveliso kunye nokungaphumeleli ngokwakho ngenxa yokungaphumeleli kwevelve, ukufezekisa iimfuno zomsebenzi wexesha elide zesixhobo. Ukongeza, ukunciphisa okanye ukuphepha ukuvuza okubangelwe ziivalve, kudala umzi-mveliso ococekileyo, owenziwe empilweni, ukuphunyezwa kwezempilo, ulawulo lwendalo.
(2) Ukuhlangabezana neemfuno zemveliso yenkqubo. Ivalve kufuneka ifezekise iimfuno zokusebenzisa uxinzelelo oluphakathi, ukusebenza, ubushushu bokusebenza kunye nokusetyenziswa, okukwaseziimfuno ezisisiseko zokukhetha iveli. Ukuba ivalve ifune ukukhusela ukugqwesa kwaye ikhuphe ivalve ephakathi, ivalve yokhuseleko kunye ne-vallow evuthiweyo; Ukuthintela i-valve ye-PHEAMIK ngexesha lenkqubo yokusebenza, yamkeleJonga i-valve; Ukuphelisa amanzi ngokuzenzekelayo, umoya kunye nenye irhasi engapheliyo eyenziwe ngombhobho we-Steam kunye nezixhobo, ngelixa uthintelwe i-steam, ivalve iya kusetyenziswa. Ukongeza, xa i-Medium iguqukele, izixhobo zokuchasana nokunganyangeki zikhethiwe.
(3) Ukusebenza ngokulula, ufakelo kunye nolondolozo. Emva kokuba ivalve ifakiwe, umqhubi kufuneka akwazi ukuchonga ngokuchanekileyo isikhokelo se-valve, uphawu lokuvula kunye nesibonisa iSignal, ukuze ajongane neempazamo ezahlukeneyo zokuxakeka. Kwangelo xesha, ulwakhiwo olukhethiweyo lwe-velic lohlobo olukhethiweyo kufuneka lube kangako, ufakelo olululo.
(4) Uqoqosho. Phantsi kwendawo yokuhlangabezana nokusetyenziswa kwesiqhelo kwemibhobho yenkqubo, i-valve enendleko eziphantsi zemveliso kunye nendlela elula kufuneka ikhethwe kangangoko kufakelwe i-valve yohlulo lwe-valve kwaye inciphise indleko zolondolozo lwe-valve kunye nolondolozo kwinqanaba elizayo.
Ukukhetha i-velo
1.Udetermineminemine Imeko yokusebenza yevali ngokwendlela yokusetyenziswa kwevalve kwisixhobo okanye kwiprojekli yenkqubo. Umzekelo, uxinzelelo oluphakathi, olusebenzayo olusebenzayo, ukusebenza kunye nobushushu bokusebenza, njl.
2.Determines Inqanaba lokusebenza lokutywina levali ngokwendalo ephakathi, indawo yokusebenza kunye neemfuno zabasebenzisi.
3.Determinemine yohlobo lweValve kunye ne-drive yendlela ngokweenjongo zevali. Iintlobo ezifanaI-vaterve yebhabhathane, Vala i-valve, i-valve yesango,ivali yokulinganisa, njl njl.
4.Ukuya kwiparamitha echanekileyo yevalve. Uxinzelelo olufanelekileyo kunye nobukhulu obuthile i-valve iya kutshatiswa kunye nombhobho wenkqubo ofakiweyo. Ezinye iivalves zichonga ubungakanani bevalve ngokwexabiso lokuhamba okanye ukukhululwa kwevali ngexesha elithile leliphakathi.
5.Determinemine ifom yoqhagamshelo lomgangatho wokuphela kwe-valve kunye nomngxunya ngokweemeko zokusebenza kunye nobukhulu bevalini. Ezinje ngeflange, i-welding, iklip okanye intambo, njl.
6.Determines Isakhiwo kunye nohlobo lohlobo lweValve ngokwesikhundla sokufaka, indawo yokufaka, kunye nobukhulu obuthile bevalve. Efana ne-rod emnyama ye-rod, i-engle filbe, ivalve yebhola, njl.
Ngokweempawu zoxinzelelo oluphakathi, olusebenzayo kunye nobushushu bokusebenza, kunyulo oluchanekileyo nolusebenzayo lwe-vall ye-valve kunye nezinto zangaphakathi.
