Umgaqo wokukhetha ivalve
(1) Ukhuseleko kunye nokuthembeka. I-Petrochemical, isikhululo samandla, i-metallurgy kunye nezinye iimfuno zokuvelisa amashishini ngokuqhubekayo, okuzinzileyo, nokusebenza komjikelo omde. Ngoko ke, i-valve efunekayo kufuneka ibe nokuthembeka okuphezulu, into enkulu yokhuseleko, ayinakubangela ukhuseleko olukhulu lwemveliso kunye nokulimala komntu ngenxa yokungaphumeleli kwevalve, ukuhlangabezana neemfuno zokusebenza kwexesha elide lesixhobo. Ukongezelela, ukunciphisa okanye ukuphepha ukuvuza okubangelwa yi-valve, ukudala i-factory ecocekileyo, ephucukileyo, ukuphunyezwa kwempilo, ukhuseleko, ulawulo lokusingqongileyo.
(2)Ukuhlangabezana neemfuno zemveliso yenkqubo. Ivalve kufuneka ihlangabezane neemfuno zokusebenzisa i-medium, i-pressure pressure, iqondo lokushisa kunye nokusetyenziswa, okuyiyona mfuneko esisiseko yokukhetha i-valve. Ukuba ivalve iyadingeka ukukhusela uxinzelelo olugqithisileyo kunye nokukhupha okuphakathi, ivalve yokhuseleko kunye nevalve yokuphuphuma iya kukhethwa; ukuthintela ivalve ephakathi ngexesha lenkqubo yokusebenza, yamkelakhangela ivalve; ukuphelisa ngokuzenzekelayo amanzi e-condensate, umoya kunye nenye igesi engagxiliyo eyenziwa kumbhobho we-steam kunye nezixhobo, ngelixa ukuthintela ukuphuma komphunga, i-valve yokudonsa iya kusetyenziswa. Ukongezelela, xa i-medium is corrosion, izinto ezifanelekileyo zokumelana ne-corrosion kufuneka zikhethwe.
(3) Ukusebenza ngokulula, ukufakwa kunye nokugcinwa. Emva kokuba i-valve ifakwe, umqhubi kufuneka akwazi ukuchonga ngokuchanekileyo isalathiso sevalve, uphawu lokuvula kunye nesignali yesalathiso, ukwenzela ukujongana neziphene ezahlukeneyo ezingxamisekileyo. Ngexesha elifanayo, isakhiwo sohlobo lwevalve ekhethiweyo kufuneka sibe kangangoko kunokwenzeka, ukufakela kunye nokugcinwa okufanelekileyo.
(4) Uqoqosho. Ngaphantsi kwesiseko sokuhlangana nokusetyenziswa okuqhelekileyo kwemibhobho yenkqubo, iivalvu ezinexabiso eliphantsi ngokwentelekiso lokwenziwa kunye nesakhiwo esilula kufuneka zikhethwe kangangoko ukunciphisa iindleko zesixhobo, kuthintelwe inkcitho yezixhobo zevalve ekrwada kunye nokunciphisa iindleko zofakelo kunye nokugcinwa kwevalve. kwinqanaba lamva.
Amanyathelo okukhetha ivalve
1.Ukumisela imeko yokusebenza yevalve ngokusetyenziswa kwevalve kwisixhobo okanye umbhobho wenkqubo. Umzekelo, ukusebenza okuphakathi, uxinzelelo lokusebenza kunye nobushushu bokusebenza, njl.
2.Misela inqanaba lokusebenza lokutywinwa kwevalve ngokwendawo yokusebenza, indawo yokusebenza kunye neemfuno zomsebenzisi.
3.Misa uhlobo lwevalve kunye nemowudi yokuqhuba ngokwenjongo yevalve. Iintlobo ezifanaivalve yebhabhathane eyomelelayo, ivalve yokukhangela, ivalve yesango,ivalve yokulinganisa, njl njl. Imowudi yokuqhuba efana neworm wheel worm, umbane, ipneumatic, njl.
4.Ngokungqinelana neparamitha yegama levalvu. Uxinzelelo oluncinci kunye nobukhulu obuqhelekileyo bevalve buya kuhambelana nombhobho wenkqubo efakwe. Ezinye iivalvu zimisela ubungakanani begama levalve ngokwesantya sokuhamba okanye ukukhutshwa kwevalve ngexesha elilinganisiweyo lendawo ephakathi.
5.Qinisekisa ifom yokudibanisa ye-valve end surface kunye nombhobho ngokweemeko zangempela zokusebenza kunye nobukhulu obuqhelekileyo be-valve. Njengeflange, i-welding, ikliphu okanye intambo, njl.
6.Ukumisela isakhiwo kunye nefom yohlobo lwevalve ngokwendawo yokufakela, indawo yokufakela, kunye nobukhulu begama levalve. Njengevalve yesango elimnyama, ivalve yeglowubhu ye-angle, ivalve yebhola esisigxina, njl.
Ngokweempawu eziphakathi, uxinzelelo olusebenzayo kunye nobushushu bokusebenza, kukhetho oluchanekileyo nolufanelekileyo lwegobolondo yevalve kunye nezixhobo zangaphakathi.
