Yintoni iValve yokuHlola
Ivalve yokukhangela sisixhobo esibalulekileyo sokulawula ulwelo, ikakhulu sisetyenziselwa ukunqanda i-medium ukuba ingabuyeli kumbhobho.
I-valve yokukhangela, eyaziwa ngokuba yi-valve engabuyiyo, i-valve yendlela enye, i-valve ye-reflux okanye i-valve yokuhlukanisa, ibhekisela kwi-valve eneendawo zokuvula kunye nokuvala (i-valve flap) ezijikelezayo kwaye zixhomekeke kubunzima bazo kunye noxinzelelo oluphakathi ukuvelisa intshukumo ukuvala umva we-medium. Umsebenzi wayo ophambili kukuvumela ulwelo ukuba luhambe kwicala elinye kuphela. Xa i-fluid ibuyela emva, i-valve flap iya kuvala ngokuzenzekelayo, ngaloo ndlela inqumle indlela yokuhamba kunye nokuthintela umonakalo obangelwa ukubuya ngasemva.
Ungamkhetha njani uMenzi weValve echanekileyo kunye noMboneleli
| Khetha umboneleli ofanelekileyo wevalve yokukhangela: Okokuqala, kufuneka ukhethe umthengisi wevalve yesango onodumo oluhle kunye namava atyebileyo. Xa ukhetha umthengisi, kufuneka uphonononge ngokungqongqo iziqinisekiso zakhe, izixhobo zokuvelisa kunye nenqanaba lenkqubo. I-NSW iya kuba liqabane lakho lomenzi wevalvu waseTshayina. |  |
| Lawula ngokungqongqo umgangatho wezinto eziluhlaza: Izinto ezisetyenziswa kwiivalvu zesango zichaphazela ngokuthe ngqo umgangatho wazo. Kuya kufuneka ukhethe ababoneleli bemathiriyeli ekrwada abakumgangatho ophezulu kwaye wenze uhlolo olungqongqo lomgangatho kunye nolawulo kwimathiriyeli ekrwada. | |
| Ukomeleza ulawulo lwenkqubo yokuvelisa: Ekuveliseni iivalve zokutshekisha, ulawulo lwenkqubo kufuneka luqiniswe, kwaye imisebenzi kufuneka iqhutywe ngokungqongqo ngokuhambelana nemigaqo yenkqubo ukuqinisekisa ukulawulwa okungqongqo kwekhonkco ngalinye ukukhusela imingcipheko yekhwalithi ebangelwa ukusebenza okungafanelekanga. | |
| Ukuphucula inkqubo yokuhlola umgangatho: Emva kokuba ukuveliswa kweevalve zesango kugqityiwe, ukuhlolwa komgangatho obanzi kunye neenkcukacha kufuneka kwenziwe. Izixhobo zokuhlola kufuneka zibe phambili kwaye zichaneke, kwaye iindlela zokuhlola kufuneka ziqhutywe ngokungqongqo ngokuhambelana nemigangatho. | |
| Yomeleza inkonzo emva kokuthengisa: Imiba esemgangathweni ephakanyiswe ngabathengi kufuneka iphendulwe ngokukhawuleza, imiba esemgangathweni evelayo kufuneka isonjululwe ngexesha elifanelekileyo, kwaye iimveliso kunye neenkonzo kufuneka ziphuculwe ngokuqhubekayo ukuze kuphuculwe ngokuqhubekayo ukwaneliseka kwabathengi. | |
Zeziphi Iindidi zeeVavu zokuHlola
Ulwahlulo lwesakhiwo seevalvu zokutshekisha

Ukuhlelwa ngendlela yofakelo lwevalve yokukhangela
Ivalve yokujonga ujingi:
Idiskhi yevalve yevalve yokujonga i-swing-shaped kwaye ijikeleza i-shaft ejikelezayo yesitulo sesitulo sevalve. Ngenxa yokuba umjelo ongaphakathi kwi-valve ulungelelaniswa, ukuchasana kokuhamba kuncinci kune-valve yokukhangela i-valve. Ifanelekile kwiziganeko zobubanzi obukhulu kunye nezinga lokuhamba okuphantsi kunye nokutshintsha okungaqhelekanga.
Phakamisa ivalve yokujonga:
Ivalve yokukhangela enediski yevalve islayidi ecaleni komgca othe nkqo osembindini womzimba wevalvu. Ivalve yokukhangela i-lift ingafakwa kuphela kumbhobho othe tye. Inxalenye ephezulu yediski yevalve kunye nenxalenye esezantsi yesivalo sevalve icutshungulwa ngemikhono yesikhokelo. Umkhono wediskhi yevalve unokuphakanyiswa ngokukhululekileyo kwaye uthotywe kumkhono wesikhokelo sevalve. Xa i-medium ihamba ezantsi, i-disc yevalve ivulwa ngokutyhala kwe-medium.
Ivalve yokujonga idiski:
Ivalve yokukhangela apho idiski ijikeleza kwi-pin shaft kwisitulo sevalve. I-valve yokujonga i-disc inesakhiwo esilula kwaye inokufakwa kuphela kwimibhobho ethe tye, kwaye ukusebenza kwayo kokutywinwa kubi.
Ivalve yokujonga umbhobho:
Ivalve apho idiski islayidi ecaleni komgca osembindini womzimba wevalvu. Ivalve yokukhangela umbhobho luhlobo olutsha lwesivalo. Incinci ngobukhulu, ilula ngobunzima, kwaye inobuchwephesha bokucwangcisa. Ngomnye wemigaqo yophuhliso lwevalve yokutshekisha. Nangona kunjalo, i-coefficient yokumelana nolwelo inkulu kancinane kunaleyo yevalve yokujonga ujingi.
Ivalve yokujonga ucinezelo:
Le valve isetyenziswa njengebhoyila yamanzi kunye nevalve yokuvala umphunga. Inemisebenzi edibeneyo yokukhangela i-valve yokuphakamisa kunye ne-valve yokumisa okanye i-angle valve. Ukongezelela, kukho ezinye iivalve zokujonga ezingafanelekanga ukufakwa kwempompo yepompo, njengama-valve asezantsi, i-spring-loaded check valves, kunye ne-Y-type check valves.
Kutheni Khetha iValve yokuHlola
Izizathu eziphambili zokukhetha i-valve yokutshekisha ziquka ukuthintela ukubuya kwamanzi, ukukhusela izixhobo kunye nokuphucula ukusebenza kakuhle kwenkqubo. Umsebenzi ophambili wevalve yokutshekisha kukuthintela ukubuya kolwelo kumbhobho kunye nokuqinisekisa ukuba ulwelo lunokuqukuqela kwicala elinye kuphela. Olu luyilo lunokukhusela ngokufanelekileyo izixhobo emonakalweni, ngakumbi kwiindawo zokusebenza ezinoxinzelelo oluphezulu, ukushisa okuphezulu okanye imidiya ebolileyo. I-valve yokutshekisha inokuqinisekisa ukuba i-fluid igeleza kwindlela eyenzelwe kwaye igweme umonakalo kwisixhobo ngenxa yokubuyela umva.
