Khangela ivalveikwabizwa ngokubaivalve yendlela enyeokanye ivalve yokukhangela, umsebenzi wayo kukuthintela okuphakathi kumbhobho ukuba ubuye umva.Ivalve evula okanye ivale ngokwayo ngokuhamba kunye nokunyanzeliswa kwe-medium ukukhusela i-medium ekubuyeni ngasemva ibizwa ngokuba yi-valve yokukhangela.Iivalvu zokukhangela zezodidi lweevalvu ezizenzekelayo.Iivalvu zokukhangela zisetyenziswa ikakhulu kwimibhobho apho i-medium ihamba kwicala elinye, kwaye ivumela kuphela i-medium ukuba ihambe kwicala elinye ukukhusela iingozi.
Ngokwesakhiwo sevalve yokutshekisha, inokwahlulwa ibe ziindidi ezintathu:phakamisa ivalve yokujonga, ivalve yokujonga ujingikwayeivelufa yokujonga ibhabhathane.Iivalvu zokukhangela zokuphakamisa zinokwahlulwa zibe ziindidi ezimbini:iivalvu zokujonga ezithe nkqokwayeiivalvu zokutshekisha ezithe tyaba.Ivalve yokujonga ujingi yohlulwe ngokweendidi ezintathu:Ivalve yokujonga ipleyiti enye, Ivalve yokujonga ipleyiti ephindwe kabinikunye nevalve yokujonga iipleyiti ezininzi.
Ezi zinto zilandelayo kufuneka ziqwalaselwe xa ufaka i-valve yokutshekisha:
1.Ungavumeli ivalve yokutshekisha ukuba ithwale ubunzima kumbhobho.Iivalve ezinkulu zokutshekisha kufuneka zixhaswe ngokuzimeleyo ukuze zingachaphazeleki ngoxinzelelo oluveliswa yinkqubo yokubhobhoza.
2.Xa ufaka, qaphela isalathiso sokuhamba okuphakathi kufuneka sihambelane nesalathiso sotolo oluphawulwe kumzimba wevalve.
3.Ukuphakamisa ivalve yokujonga i-flap ethe nkqokufuneka ifakwe kumbhobho othe nkqo.
4.Iphakamisa uhlobo oluthe tye ivalve yokukhangela i-flapkufuneka ifakwe kumbhobho othe tye.
Iingqwalasela zofakelo:
1.Xa ubeka umbhobho, qaphela ukuba wenze ulwalathiso oludlulayo lwe ivalve yokujonga iwaferihambelana nesikhokelo sokuhamba kolwelo, Ifakwe kumbhobho othe nkqo;Kwimibhobho ethe tye, beka ivalve yokujonga iwafer ngokuthe nkqo.
2.Sebenzisa ityhubhu ye-telescopic phakathi kwevalve yokujonga i-wafer kunye nevalve yebhabhathane, ungaze uyidibanise ngokuthe ngqo kwezinye iivalvu.
3.Kugweme ukongeza amalunga ombhobho kunye nezithintelo ngaphakathi kwendawo yokusebenza yepleyiti yevalve.
4.Musa ukufaka isinciphisi phambi okanye emva kwevalve yokujonga i-wafer.
5.Xa ufaka i-valve yokujonga i-wafer ejikeleze i-elbow, qaphela ukushiya indawo eyaneleyo.
6.Xa ufaka ivalve yokujonga i-wafer kwindawo yokuphuma kwempompo, shiya isithuba esiphindwe kathandathu ubuncinane kwidayamitha yevalvu ukuqinisekisa ukuba ipleyiti yebhabhathane ichaphazeleka ekugqibeleni lulwelo.
