Iindidi zokuHlola iiVavu

Khangela ivalve, eyaziwa ngokuba yi-valve yendlela enye okanye i-valve yokukhangela, yeyodidi lwevalve oluzenzekelayo, kwaye umsebenzi walo kukuthintela ukubuya ngasemva kwe-medium kumbhobho.Ivalve esezantsi esetyenziselwa ukufunxa impompo ikwaluhlobo lwevalve yokukhangela.I-disc ye-valve yokutshekisha ivuliwe phantsi kwesenzo soxinzelelo lwe-fluid, kwaye i-fluid iphuma kwi-inlet ukuya kwindawo yokuphuma.Xa uxinzelelo lwe-inlet luphantsi kune-outlet, i-valve flap ivalwe ngokuzenzekelayo phantsi kwesenzo sokwahlukana koxinzelelo lwe-fluid, ubunzima kunye nezinye izinto zokuthintela umbane ukuba ungabuyeli umva.

Ulwahlulo lwee-valve zokutshekisha lunokwahlulwa lube ziintlobo ezahlukeneyo ngokwezinto eziphathekayo, umsebenzi kunye nesakhiwo.Oku kulandelayo kuya kwazisa iintlobo zeevalvu zokutshekisha kule miba mithathu.

1. Ukuhlelwa ngokwezinto eziphathekayo

1) I-valve yokujonga intsimbi

2) I-valve yokukhangela ubhedu

3) I-valve yokujonga insimbi engenasici

2. Ukuhlelwa ngokomsebenzi

1) Ivalve yokujonga ethule

2) Ivalve yokujonga ibhola

Ivalve yokukhangela ibhola ikwabizwa ngokuba ivelufa yokukhangela amanzi amdaka.Umzimba we-valve wamkela isakhiwo esipheleleyo setshaneli, esinenzuzo yokuhamba okukhulu kunye nokuchasana okuphantsi.Ibhola isetyenziswe njengediski yevalve, efanelekile kuthungelwano lwemibhobho yogutyulo lwasekhaya kunye neshishini kunye ne-viscosity ephezulu kunye nezinto eziqinileyo ezimisiweyo.

3. Ukuhlelwa ngokwesakhiwo

1) Phakamisa ivalve yokukhangela

2) Ivalve yokujonga ujingi

3) Ivalve yokukhangela ibhabhathane

Ubume bevalve yokukhangela i-lift ngokuqhelekileyo bufana nevalve yeglowubhu.I-disc ye-valve ihla inyuka inyuka ngomgca kwitshaneli, kwaye isenzo sinokwethenjelwa, kodwa ukuxhathisa ulwelo kukhulu, kwaye kufanelekile kwizihlandlo ezinobubanzi obuncinci.Ivalve yokukhangela yokuphakamisa yahlulwe yaba ziindidi ezimbini: uhlobo oluthe tye kunye nohlobo oluthe nkqo.Iivalvu zokujonga ukutyhutyha ngokuthe tye zinokufakelwa kuphela kwimibhobho ethe tye, ngelixa iivalvu zokujonga ezithe nkqo kunye neevalvu ezisezantsi zifakwe ngokubanzi kwimibhobho ethe nkqo, kwaye ophakathi uhamba ukusuka ezantsi ukuya phezulu.

I-disc yevalve yokukhangela i-swing ijikeleza kwi-axis yokujikeleza.Ukumelana kwayo nolwelo ngokuqhelekileyo kuncinci kunoko kwevalve yokukhangela i-lift, kwaye ifanelekile kwizihlandlo ezinobubanzi obukhulu.Ngokwenani leediski, ivalve yokukhangela i-swing inokwahlulwa ibe ziindidi ezintathu: uhlobo lwe-disc enye yokujingi, uhlobo lwe-disc lokujinga kabini kunye nodidi lwe-disc lokujinga.Ivalve yokujonga i-flap enye ifanelekile ngokubanzi kwizihlandlo eziphakathi.Ukuba ivalve yokujonga i-flap enye isetyenziselwa imibhobho yobubanzi obukhulu, ukuze kuncitshiswe uxinzelelo lwehamile yamanzi, kungcono ukusebenzisa ivalve yokujonga evala kancinci enokunciphisa uxinzelelo lwehamile yamanzi.Ivalve yokujonga ujingi kabini ilungele imibhobho emikhulu nephakathi.Ivalve yokujonga i-wafer double flap swing incinci ngokwesakhiwo kwaye ilula ngobunzima, kwaye luhlobo lwevalve yokukhangela enophuhliso olukhawulezayo.Ivalve yokujonga ijingi ebanzi ilungele imibhobho emikhulu edayamitha.

Isikhundla sokufakela i-valve yokukhangela i-swing ayikhawulelwanga, ngokuqhelekileyo ifakwe kumbhobho othe tye, kodwa inokufakwa kumbhobho othe nkqo okanye umbhobho wokulahla.

Ubume bevalve yokukhangela ibhabhathane iyafana nevalve yebhabhathane.Isakhiwo sayo silula, ukuchasana kokuhamba kuncinci, kwaye uxinzelelo lwehamile yamanzi luncinci.

Iindlela zokudibanisa i-valve yokutshekisha ziquka uxhulumaniso lwe-clip, uxhumano lwe-flange, uxhulumaniso lwe-threaded, i-butt welding / socket welding connection, njl.Izixhobo zomzimba zeValve zi-WCB, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L).Khetha izixhobo ezahlukeneyo zemidiya eyahlukeneyo.Ivalve yokukhangela ingasetyenziswa kumanzi, umphunga, ioli, i-nitric acid, i-acetic acid, i-oxidizing medium, urea kunye nezinye imidiya.

Xa ufaka i-valve yokutshekisha, ingqwalasela ekhethekileyo kufuneka ihlawulwe kwicala lokuhamba kwe-medium, kwaye indlela yokuhamba eqhelekileyo ye-medium kufuneka ihambelane nesalathiso sotolo olubonakaliswe kumzimba wevalve, ngaphandle koko ukuhamba okuqhelekileyo kwendawo kuya kungena. unqunyulwe.Ivalve esezantsi kufuneka ifakwe kwisiphelo esisezantsi somgca wokufunxa wempompo.

Xa i-valve yokukhangela ivaliwe, uxinzelelo lwehamile yamanzi luya kuveliswa kumbhobho, oya kubangela umonakalo kwi-valve, umbhobho okanye izixhobo kwiimeko ezinzima, ngokukodwa kwimibhobho yomlomo omkhulu okanye imibhobho yoxinzelelo oluphezulu, nceda uhlawule ingqalelo.
