Ukoyisa ukuchasana kwentwasahlobo kwenza i-valve ivule okanye ivale.Xa uxinzelelo oluphakathi kwi-inlet end end lungaphantsi kwe-inlet end, i-valve yokujonga ngokuthe nkqo: ngenxa yoxinzelelo lwe-medium kwi-inlet end of the pipeline.Umthombo utyhala i-valve core kwisitulo sevalve ukuvala ivalve, ukuthintela i-medium ukuba ingabuyeli ngasemva, ngoko inomsebenzi ongabuyiyo.Iivalvu zokujonga ezithe nkqo zisetyenziswa kakhulu kwiikhemikhali, igesi yepetroleum engamanzi, ulwelo kunye namanye amashishini.Ngokwesakhiwo sevalve yokutshekisha, inokwahlulwa ibe ziindidi ezintathu: ivalve yokukhangela iphakamisa, ivalve yokujonga i-valve kunye nevalve yokukhangela ibhabhathane.
Ivalve esetyenziselwa ukuthintela i-medium ukuba ingabuyeli ngasemva ikwabizwa ngokuba ivelufa yokutshekisha, ivalve yendlela enye, ivalve ejikelezayo, kunye nevalve yoxinzelelo yangasemva.I-valve yokutshekisha luhlobo lwe-valve oluzenzekelayo, umsebenzi walo oyintloko kukuthintela ukuhamba ngasemva kwe-medium, ukuthintela impompo kunye ne-motor drive ekubuyiseleni umva, kunye nokukhutshwa kwe-container medium.Iivalvu zokutshekisha zingasetyenziselwa ukubonelela ngemibhobho apho uxinzelelo lunokwenyuka ukuya kwisistim encedisayo edlula uxinzelelo lwenkqubo.Iivalve zokujonga zinokwahlulwa zibe ziivalve zokujonga ujingi (ezijikelezayo ngokweziko lomxhuzulane) kwaye ziphakamise iivalvu zokujonga (zihamba nge-axis).Umsebenzi wolu hlobo lwevalve kukuvumela kuphela i-medium ukuba ihambe kwicala elinye kwaye ithintele ukuhamba kwendlela.Ngokuqhelekileyo olu hlobo lwevalve lusebenza ngokuzenzekelayo phantsi kwesenzo soxinzelelo lwe-fluid ehamba kwicala elinye, i-valve flap ivula;xa ulwelo luqukuqela kwelinye icala, uxinzelelo lwe-fluid kunye ne-self-coincidence ye-valve flap isebenza kwisitulo sevalve, ngaloo ndlela kunqunyulwa ukuhamba.Phakathi kwabo, ivalve yokukhangela intambo yangaphakathi kunye nevalve yokujonga ethe nkqo ibhekisa ekuvuleni okuzenzekelayo kunye nokuvalwa kwevalve ngokuxhomekeke ekuhambeni kwe-medium ngokwayo.Iivalvu zokutshekisha ezidityanisiweyo zezolu hlobo lwesivalo, kubandakanywa iivalve zokujonga ujingi kunye neevalvu zokukhangela zokuphakamisa.Ivalve yokujonga ujingi inesixhobo sekhonkco eliphakathi kunye nediski yevalvu efana nocango oluhlala ngokukhululekileyo kumphezulu wesihlalo sevalve ethambekeleyo.Ukuqinisekisa ukuba isivalo sevalve sinokufikelela kwindawo eyiyo yomphezulu wesihlalo sevalve ngalo lonke ixesha, isivalo sevalve siyilwe ngendlela yetyathanga ukuze isivalo sevalve sibe nesithuba esaneleyo sokujika kwaye senza ukuba ivalve ibe mhlophe kwaye iqhagamshelene ngokupheleleyo. isihlalo sevalve.I-valve clack inokwenziwa ngentsimbi, isikhumba, irabha, okanye isigqubuthelo sokwenziwa sinokufakwa kwintsimbi, ngokuxhomekeke kwiimfuno zokusebenza.Xa ivalve yokujonga ujingi ivulwe ngokupheleleyo, uxinzelelo lolwelo luphantse lungathintelwa, ngoko ke ukuhla koxinzelelo ngevalve kuncinci.Idiskhi yevalve yevalve yokukhangela i-lift ihleli kwindawo yokutywina yesitulo sevalvu kumzimba wevalvu.Ngaphandle kokuba i-disc inokuphakanyiswa kwaye ithotywe ngokukhululekileyo, yonke le valve ifana nevalve yokuvala.Uxinzelelo lwe-fluid luphakamisa i-disc ukusuka kwindawo yokutywinwa kwesihlalo se-valve, kunye nokubuyela umva kwe-medium kubangela ukuba i-disc ibuyele esihlalweni kwaye inqumle ukuhamba.Ngokwemiqathango yokusetyenziswa, i-disc ye-valve ingaba yinkcenkceshe yonke, okanye inokuba luhlobo lwe-rubber pad okanye i-rubber ring efakwe kwi-disc frame.Njengevalve yokumisa, ukudlula kwamanzi kwivalve yokujonga i-lift nayo incinci, ngoko ke ukuhla koxinzelelo ngevalve yokukhangela i-lift likhulu kunelo levalve yokujonga i-swing, kwaye ukuhamba kwevalve yokukhangela i-lift akuthinteli kangako.

I-Nortech ngomnye wabavelisi abakhokelayo bevalvu yeshishini e-China kunye nesiqinisekiso somgangatho we-ISO9001.
