Yintoni iValve yokujonga
Ivalvu yokujonga sisixhobo esibalulekileyo sokulawula ulwelo, esisetyenziswa kakhulu ukuthintela ukuba i-medium ingabuyeli kwipayipi.
Ivalvu yokujonga, eyaziwa ngokuba yivalvu engabuyiyo, ivalvu yendlela enye, ivalvu ye-reflux okanye ivalvu yokwahlukanisa, ibhekisa kwivalvu apho iindawo zayo zokuvula nezokuvala (i-valve flap) zingqukuva kwaye zixhomekeke kubunzima bazo kunye noxinzelelo oluphakathi ukuvelisa intshukumo yokuthintela ukuhamba kwe-medium. Umsebenzi wayo ophambili kukuvumela ulwelo ukuba luhambe kwicala elinye kuphela. Xa ulwelo lubuyela umva, i-valve flap iya kuvala ngokuzenzekelayo, ngaloo ndlela inqumle indlela yokuhamba kwaye ithintele umonakalo obangelwa kukuhamba kwe-medium.
Indlela Yokukhetha Ivalvu Yokujonga Echanekileyo Umenzi kunye Nomthengisi
| Khetha umthengisi weevalvu zokujonga ezifanelekileyo: Okokuqala, kufuneka ukhethe umthengisi weevalvu zesango onegama elihle namava amaninzi. Xa ukhetha umthengisi, kufuneka uhlolisise ngokungqongqo iziqinisekiso zakhe, izixhobo zemveliso kunye nenqanaba lenkqubo. I-NSW iya kuba liqabane lakho lomenzi weevalvu waseTshayina. |  |
| Lawula ngokungqongqo umgangatho wezinto ezikrwada: Izinto ezisetyenziswa kwiivalvu zesango zichaphazela ngqo umgangatho wazo. Kufuneka ukhethe ababoneleli bezinto ezikrwada ezikumgangatho ophezulu kwaye wenze uhlolo olungqongqo lomgangatho kunye nolawulo lwezinto ezikrwada. | |
| Qinisa ulawulo lwenkqubo yemveliso: Kwimveliso yeevalvu zokujonga, ulawulo lwenkqubo kufuneka luqiniswe, kwaye imisebenzi kufuneka yenziwe ngokungqongqo ngokwemigaqo yenkqubo ukuqinisekisa ulawulo olungqongqo lwekhonkco ngalinye ukuthintela iingozi zomgangatho ezibangelwa kukungasebenzi kakuhle. | |
| Phucula inkqubo yokuhlola umgangatho: Emva kokuba kugqityiwe ukuveliswa kweevalvu zesango, kufuneka kwenziwe uhlolo olupheleleyo noluneenkcukacha zomgangatho. Izixhobo zokuhlola kufuneka zibe ziphucukile kwaye zichaneke, kwaye iindlela zokuhlola kufuneka zisetyenziswe ngokungqongqo ngokwemigangatho. | |
| Qinisa inkonzo emva kokuthengisa: Imiba yomgangatho ephakanyiswe ngabathengi kufuneka iphendulwe ngokukhawuleza, imiba yomgangatho evelayo kufuneka isonjululwe ngexesha elifanelekileyo, kwaye iimveliso kunye neenkonzo kufuneka ziphuculwe ngokukhutheleyo ukuze kuphuculwe ulwaneliseko lwabathengi rhoqo. | |

Uhlu ngokwendlela yokufaka ivalvu yokujonga
Ivalvu yokujonga iswing:
Idiski yevalvu yevalvu yokujonga iswing imilo yediski kwaye ijikeleza umgodi ojikelezayo wetshaneli yesihlalo sevalvu. Ngenxa yokuba itshaneli engaphakathi kwevalvu ilungelelanisiwe, ukumelana nokuhamba kwamanzi kuncinci kunokwevalvu yokujonga ukuphakama. Ifanelekile kwiimeko ezinkulu ezinesantya esiphantsi sokuhamba kwamanzi kunye notshintsho lokuhamba kwamanzi olungaqhelekanga.
Ivalvu yokujonga ukuphakamisa:
Ivalvu yokujonga enediski yevalvu etyibilika kumgca ophakathi we-valve. Ivalvu yokujonga ukuphakama inokufakelwa kuphela kumbhobho othe tyaba. Inxalenye ephezulu yediski yevalvu kunye nenxalenye esezantsi yesiciko sevalvu zicutshungulwa ngemikhono yesikhokelo. Isleeve yesikhokelo sediski yevalvu inokuphakanyiswa ngokukhululekileyo kwaye yehliswe kwisleeve yesikhokelo sevalvu. Xa i-medium ihla iye ezantsi, idiski yevalvu ivulwa ngokutyhalwa yi-medium.
Ivalvu yokujonga idiski:
Ivalvu yokujonga apho idiski ijikeleza khona i-pin shaft kwisitulo sevalvu. Ivalvu yokujonga idiski inesakhiwo esilula kwaye inokufakelwa kuphela kwiipayipi ezithe tye, kwaye ukusebenza kwayo kokutywina akukuhle.
Ivalvu yokujonga umbhobho:
Ivalvu apho idiski ityibilika khona kumgca osembindini womzimba wevalvu. Ivalvu yokujonga umbhobho luhlobo olutsha lwevalvu. Incinci ngobukhulu, ilula ngobunzima, kwaye inetekhnoloji yokucubungula elungileyo. Yenye yeendlela zophuhliso lwevalvu yokujonga. Nangona kunjalo, i-coefficient yokumelana nolwelo inkulu kancinci kunevalvu yokujonga i-swing.
Ivalvu yokujonga ucinezelo:
Le valve isetyenziswa njengevalvu yokucheba amanzi kunye nevalvu yokunqunyulwa komphunga kwibhoyila. Inemisebenzi edibeneyo yevalvu yokujonga ukuphakama kunye nevalvu yokumisa okanye ivalvu ye-angle. Ukongeza, kukho ezinye iivalvu zokujonga ezingafanelekanga ukufakwa kwepompo, ezifana neevalvu ezisezantsi, iivalvu zokujonga ezifakwe entwasahlobo, kunye neevalvu zokujonga uhlobo lwe-Y.
Kutheni Ukhetha Ivalvu Yokujonga
Izizathu eziphambili zokukhetha ivalvu yokujonga ziquka ukuthintela ukubuya kolwelo, ukukhusela izixhobo kunye nokuphucula ukusebenza kakuhle kwenkqubo. Umsebenzi ophambili wevalvu yokujonga kukuthintela ukubuya kolwelo kwipayipi kunye nokuqinisekisa ukuba ulwelo luhamba kwicala elinye kuphela. Olu yilo lunokukhusela ngokufanelekileyo izixhobo ekonakalisweni, ingakumbi kwiindawo zokusebenza ezinoxinzelelo oluphezulu, ubushushu obuphezulu okanye imidiya ebolileyo. Ivalvu yokujonga inokuqinisekisa ukuba ulwelo luhamba kwicala eliyilelweyo kwaye iphephe ukonakala kwezixhobo ngenxa yokubuyela umva.
