Khangela iivalvu, kwaziwa njengekhangela iivalveokanye iivalve zokukhangela, zisetyenziselwa ukuthintela ukubuyela ngasemva kwemidiya kumbhobho. Ivalve yonyawo lokufunxa impompo yamanzi ikwayinxalenye yodidi lwevalvu yokutshekisha. Amalungu okuvula kunye nokuvala axhomekeke ekuhambeni kunye nokunyanzeliswa kwe-medium ukuvula okanye ukuvala ngokwawo, ukuze kuthintelwe i-medium ukuba ihambe ngasemva. Iivalvu zokukhangela zezodidi lwevalvu oluzenzekelayo, ezisetyenziswa ikakhulu kwimibhobho apho i-medium iqukuqela kwicala elinye, kwaye ivumela kuphela i-medium ukuba ihambe kwicala elinye ukunqanda iingozi.
Ngokwesakhiwo, ivalve yokukhangela inokwahlulwa ibe ziindidi ezintathu: ivalve yokukhangela yokuphakamisa,ivalve yokujonga ujingikwayeivelufa yokujonga ibhabhathane. Iivalvu zokukhangela eziphakamisayo zinokwahlulwa zibe ziivalve zokujonga ezithe nkqo kunye neevalvu zokujonga ezithe tye.
Kukho iintlobo ezintathu zeswing check valves: iivalve zokujonga i-single-lobe, i-double-flap check valves kunye ne-multi-flap check valves.
Ivalve yokukhangela ibhabhathane yivalve yokujonga ngokuthe tye, kwaye ezi zivalo zingentla zinokwahlulwa zibe ziindidi ezintathu: ivalve yokukhangela uqhagamshelo oludityanisiweyo, ivalve yokukhangela uqhagamshelo lweflange kunye nevalve yokukhangela edityanisiweyo.
Ingqalelo kufuneka ihlawulwe kule miba ilandelayo xa kufakelwa iivalvu zokutshekisha:
1. Musa ukwenza ikhangela ivalvethwala ubunzima kumbhobho, kwaye i-valve yokukhangela enkulu kufuneka ixhaswe ngokuzimeleyo ukuze ingachaphazeleki ngoxinzelelo olwenziwa ngumbhobho.
2. Ngexesha lofakelo, nikela ingqalelo kwindlela yokuhamba okuphakathi kufuneka ihambelane nesalathiso sotolo oluvotelwe ngumzimba wevalve.
3. Ivalve yokukhangela i-flap ephakanyisiweyo kufuneka ifakwe kumbhobho othe nkqo.
4. Ivalve yokukhangela i-flap ephakanyisiweyo kufuneka ifakwe kumbhobho othe tye. Yintoni ivalve yokujonga nkqo? Iivalve zokujonga ezichanekileyo zisetyenziswa ngokubanzi kwiinkqubo apho kuyimfuneko ukukhusela umva weendaba, njengokuphuma kwempompo, isiphelo sokuzaliswa kwamanzi ashushu, kunye nokuphela kokufunxa kwempompo ye-centrifugal. Umsebenzi wayo kukuthintela imiphumo enokuthi yenzeke ekuphumeni kwe-medium, umzekelo, ukuba ukuphuma kwempompo akuxhotyiswanga nge-valve yokujonga i-vertical vertical, ukubuya kwamanzi okubuya kwesantya esiphezulu kuya kubangela impembelelo enkulu kwi-impeller yepompo xa ipompo iyeka ngokukhawuleza; Ukuba ivalve yokujonga eme nkqo (ivalve yeenyawo) ayifakwanga ekupheleni kokufunxa kwempompo ye-centrifugal, impompo kufuneka izaliswe ngalo lonke ixesha impompo ivuliwe.
Eminye imibuzo, ungaqhakamshelana ne-TWS VALVE evelisa ngokuyintlokoivalve ehleli ibhabhathane ehleliyo, ivalve yesango, ivalve yokukhangela, i-Y-strainer, njl.
