1. Ivalveumgaqo wokukhetha:
Ivalve ekhethiweyo kufuneka ihlangabezane nale migaqo ilandelayo.
(1) Ukhuseleko kunye nokuthembeka kwepetrochemical, isikhululo samandla, i-metallurgy kunye namanye amashishini afuna ukuqhubeka, ukuzinza, ukusebenza komjikelo omde. Ke ngoko, ivalve kufuneka ibe nokuthembeka okuphezulu, into yokhuseleko, hayi ngenxa yokungaphumeleli kwevalvu okubangele ukhuseleko olukhulu lwemveliso kunye nengozi yokulimala komntu, ukuhlangabezana nemfuneko yesixhobo sokusebenza komjikelo omde, ukuveliswa okuqhubekayo komjikelezo kuyinzuzo, ukongeza, ukunciphisa okanye ukuphepha ukuvuza okubangelwayo. ngesivalo, ukudala ecocekileyo, umzi-mveliso ophucukileyo, HSE (okt, impilo, ukhuseleko, okusingqongileyo) ulawulo.
(2) Ukuhlangabezana neemfuno zevalve yokuvelisa inkqubo kufuneka ihlangabezane nokusetyenziswa koxinzelelo oluphakathi, uxinzelelo olusebenzayo, ubushushu obusebenzayo kunye neemfuno zokusetyenziswa, okukwayimfuno esisiseko yokukhetha ivalve. Ukuba idinga indima yokukhusela i-valve overpressure, ukukhupha okuphakathi, kufuneka ukhethe ivalve yokhuseleko, ivalve yokuphuphuma, kufuneka uthintele inkqubo yokusebenza kwe-medium backflow, kufuneka isebenzise i-valve yokukhangela, kufuneka ikhuphe ngokuzenzekelayo umbhobho we-steam kunye nezixhobo ze-condensate, umoya kunye nezinye azikwazi ukudibanisa. igesi, kunye nokuthintela ukuphuma komphunga, kufuneka ukhethe ivalve yokukhupha amanzi. Ukongezelela, xa i-medium is corrosion, izinto ezifanelekileyo zokumelana ne-corrosion kufuneka zikhethwe.
(3) Emva kokusebenza, ukufakwa, ukuhlolwa (ukugcinwa) ukulungiswa kwevalve, umqhubi kufuneka akwazi ukuchonga ngokuchanekileyo isalathiso sevalve, iimpawu zokuvula, imiqondiso ebonisayo, kulula ukujongana nexesha elifanelekileyo kunye nokujongana neziphene ezahlukeneyo zikaxakeka. Ngexesha elifanayo, isakhiwo sohlobo lwe-valve ekhethiweyo kufuneka sibe kude kangangoko kunokwenzeka kwiphepha le-cylinder, ukufakela, ukuhlolwa (ukugcinwa) ukulungiswa ngokufanelekileyo.
(4) Uqoqosho Kwisiseko sokuhlangabezana nokusetyenziswa okuqhelekileyo kwemibhobho yenkqubo, iivalvu ezinexabiso eliphantsi ngokwentelekiso lokwenziwa kunye nolwakhiwo olulula kufuneka zikhethwe kangangoko ukunciphisa iindleko zesixhobo, kuthintelwe inkcitho yemathiriyeli ekrwada yevalvu kunye nokunciphisa i-valve ekrwada. iindleko zofakelo lwevalvu kunye nokugcinwa kwinqanaba lamva.
2. Amanyathelo okukhetha ivalvu:
Khetha iivalvu ngokubanzi landela la manyathelo alandelayo.
1. Qinisekisa imeko yokusebenza yevalve ngokusetyenziswa kwevalve kwisixhobo okanye kwipayipi yenkqubo. Umzekelo, ukusebenza okuphakathi, uxinzelelo lokusebenza kunye nobushushu bokusebenza, njl.
2. Qinisekisa inqanaba lokusebenza lokutywinwa kwevalve ngokwendawo yokusebenza, indawo yokusebenza kunye neemfuno zomsebenzisi.
3. Qinisekisa uhlobo lwevalve kunye nemodi yokuqhuba ngokwenjongo yevalve. Iindidi ezinjenge-valve yokusika, i-valve yokulawula, i-valve yokhuseleko, ezinye iivalve ezikhethekileyo, njl.
4. Khetha ngokweeparamitha zegama levalve. Uxinzelelo oluncinci kunye nobukhulu obuqhelekileyo bevalve buya kuhambelana nombhobho wenkqubo efakwe. I-valve ifakwe kwipayipi yenkqubo, ngoko ke imeko yayo yokusebenza kufuneka ihambelane nokukhethwa koyilo lombhobho wenkqubo. Emva kokuba inkqubo eqhelekileyo kunye noxinzelelo lwegama lombhobho lumiselwe, uxinzelelo lwevalvu, ubungakanani begama kunye noyilo lwevalvu kunye nemigangatho yokwenziwa inokumiselwa. Ezinye iivalvu zimisela ubungakanani begama levalve ngokwesantya sokuhamba okanye ukukhutshwa kwevalve ngexesha elilinganisiweyo lendawo ephakathi.
5. Ukugqiba ifom yokudibanisa ye-valve end surface kunye nombhobho ngokweemeko zangempela zokusebenza kunye nobukhulu obuqhelekileyo be-valve. Njengeflange, i-welding, ikliphu okanye intambo, njl.
6. Qinisekisa ubume kunye nefom yohlobo lwevalve ngokwendawo yokufakela, indawo yokufakela, kunye nobukhulu begama levalve. Njengevalve yesango elimnyama, ivalve yeglowubhu ye-angle, ivalve yebhola esisigxina, njl.
7. Ngokweempawu ze-medium, uxinzelelo lokusebenza kunye nobushushu bokusebenza, kukhetho oluchanekileyo nolufanelekileyo lwegobolondo yevalve kunye nezixhobo zangaphakathi.
