Ivalve yokumisa kunye nenkunkuma(misa ivalve yenkunkuma) luphuculo olusekwe kwivalve yokumisa. Umngxuma owongezelelweyo wokuhambisa amanzi ugrunjwa kumzimba wevalvu onokuvulwa kwaye ucinywe ngesivalo sevalve yokuvala.. Isetyenziswa ngokuqhelekileyo kwiinkqubo zemibhobho kunye nokunkcenkceshela, ngakumbi kwiitephu zangaphandle kunye neenkqubo zokutshiza. Umsebenzi wayo ophambili kukunqumla amanzi kwaye ngaxeshanye ukhuphe amanzi ashiyekileyo kumbhobho ngasemva kwevalve., ukuthintela umonakalo ekukhenkceni nasekuqhekekeni.

Yintoni iValve yokuMisa kunye neNkunkuma?

A misa kunye nevalve yenkunkuma yivalve enemisebenzi emininzi edibanisa iimpawu zevalve yokumisa kunye nevalve yokukhupha amanzi. Ivumela abasebenzisi ukuba bangayeki kuphela ukuhamba kwamanzi kodwa bakhuphe amanzi ashiyekileyo kumbhobho osezantsi. Oku kukhupha amanzi kubalulekile kwimimandla ethanda ukukhenkceka, inokuthintela amanzi avalelekileyo ukuba angandi emva komkhenkce kunye nokugqabhuka kwemibhobho.

Igama elithi 'Yeka kunye neValve yokuLahlwa’ iquka ‘inkunkuma’ kuba ivumela amanzi asekupheleni kombhobho ukuba akhutshwe, nto leyo ilingana nokumosha amanzi. Ngokuqhelekileyo zifumaneka kwiindawo zokuhlala kunye nezorhwebo, ukulawula unikezelo lwamanzi kwiitephu zangaphandle, iinkqubo zokutshiza, kunye nezinye izinto ezidityanisiweyo kwiindawo ezibandayo.

Isebenza njani iValve yeNkunkuma yokuyeka?

Umngxuma wokukhupha imanuwali kumzimba wevalve sisitshixo sokuMisa kunye nokusebenza kweNkunkuma yeValve. Xa kuthelekiswa neevalvu zemveli zokumisa, xa iValve yokumisa iNkunkuma ivaliwe, unokuvula umngxuma wokukhupha kwaye uvumele amanzi aphume kumbhobho, ukuvumela umoya ungene. Oku kuthintela amanzi ekubeni ngumkhenkce kwaye ande, enokubangela ukuba umbhobho ugqabhuke.

Misa kunye nokuLahlwa kweDiyagram yeValve:

• Umngxuma wokukhupha amanzi kwaye isivalo sevalve yokuvala ngamacandelo aphambili e-Stop and Waste Valves

Misa kunye neNkunkuma yeValves yokuFafaza inkqubo:

Izivalo zokumisa kunye nenkunkuma zibalulekile kwiinkqubo zokutshiza, ngakumbi kwimimandla enobusika obuqhaqhazelisa amazinyo. Ngokukhupha amanzi kwimigca yokufefa phambi kobusika, abaninimzi banokuwuthintela umonakalo onexabiso elikhulu obangelwa kukukhenkceza nokwandisa amanzi. Ezi zivalo ziqhele ukufakwa ekuqaleni kwendawo nganye yokutshiza, evumela indawo yodwa yodwa kunye nokukhupha amanzi. Le ndlela ekujoliswe kuyo ivumela ukugcinwa okanye ukulungiswa kwindawo ethile ngaphandle kokuvala yonke inkqubo yokufafaza.

Iimeko zokuSetyenziswa kunye nosetyenziso:

• IiFaucets zangaphandle: Ukukhusela iitephu zangaphandle ekukhenkcezini sesona sixhobo siphambili sokumisa iivalvu zenkunkuma.
• Iinkqubo zokutshiza: Kubalulekile kwiinkqubo zokutshiza zasebusika kunye neendawo ezizimeleyo zokugcinwa.
• Amadama okuqubha: Isetyenziselwa ukukhupha iintambo zamanzi ezibonelela ngezixhobo zamadama.
• Iinkqubo zokunkcenkceshela: Iyafana neenkqubo zokutshiza, zikhusela iintambo zokunkcenkceshela ekukhenkceni.
• Ukulungiswa kwemibhobho: Ukuvumela iindawo ezizimeleyo zemibhobho ukuba zikhutshwe ukuze zilungiswe ngaphandle kokuchaphazela unikezelo lwamanzi lonke.

Iindidi zokumisa kunye neeVave zeNkunkuma:

Izivalo zokumisa kunye nenkunkuma ziyafumaneka kwiindlela ezahlukeneyo, kubandakanya:

• Yeka & Inkunkuma Iglobhu Ivali: kukho umngxuma omncinci wokukhupha kumzimba wevalvu
• Yeka & Inkunkuma Ibhola Ivali: kukho umngxuma omncinci wokukhupha amanzi ebholeni

Ngokwendlela yoqhagamshelwano, inokwahlulwa ibe:

• udibaniso olunemisonto Yeka & Iivalvu zeNkunkuma
• Ukuwelda CXC Yeka & Iivalvu zeNkunkuma (ISolder x Solder)

Izixhobo kunye neMigangatho:

Yeka & iivalve zenkunkuma ziqhele ukwenziwa ngobhedu kunye nobhedu. Ukukhethwa kwezinto eziphathekayo kuxhomekeke kwisicelo kunye neekhowudi zemibhobho yendawo. Kubalulekile ukukhetha iivalvu ezihlangabezana nemigangatho yoshishino efanelekileyo, ezifana nezo zisetwe yi-ANSI (Iziko leMigangatho yeSizwe yaseMelika) kunye ne-ASTM(Umbutho waseMelika woVavanyo lweMathiriyeli), ukuqinisekisa umgangatho kunye nokuthembeka.

Indlela yokufaka okanye ukubuyisela indawo yokumisa & ivalve yenkunkuma?

Ukuba ufaka isitophu & ivelufa yenkunkuma kumbhobho okhoyo, kufuneka ukhethe ukuwelda iCXC yokumisa kunye nevalve yenkunkuma.

• Ekuqaleni, ukulinganisa ubude bevalve yokumisa inkunkuma kwaye uthabathe ubude bamacandelo amabini emibhobho yamanzi afakwe kwivalve.
• Sika ubude obuhambelanayo kumbhobho wamanzi oza kufakwa.
• Faka isambatho esincinci sesamente kumbhobho olingana nobunzulu besokethi kwivalve. Qinisekisa ukuba akukho ndawo ingagqunywanga kwinxalenye yombhobho kwivalve.
• Kwakhona, sebenzisa umaleko obhityileyo wesamente ngaphakathi kwisokethi kwivalve.
• Faka ivalve, shushumbisa umdibaniso ngetotshi, kwaye uyitywine ngemicu yesolder.

Yeka kwaye iivalvu zenkunkuma ziyavuza?

Ezinye iintlobo zokumisa & iivalve zenkunkuma azinasivalo. Ngoko xa ivaliwe, Amanzi kumbhobho ekupheleni ngasemva kwevalve aya kuphuma ngokuthe ngqo kumngxuma wokuhambisa amanzi. Kubonakala ngathi i-valve yokumisa kunye nenkunkuma iyavuza. Subanexhala, ilungile.

Ukuqukumbela:

Yeka & iivalve zenkunkuma yenye yezona zivalo zibalulekileyo kwimibhobho yangaphandle kwiindawo ezibandayo. Ngokukodwa kwintsimi ye-plumbing kunye neenkqubo zokunkcenkceshela, ukunika isisombululo esilula kodwa esisebenzayo sokuthintela umonakalo owenziwe ngumkhenkce kunye nokuququzelela ukulungiswa. Ukuqonda ukusebenza kwazo, izicelo, kwaye ukusetyenziswa ngokufanelekileyo kubalulekile kubaninimzi, abatywini, kunye neengcali zokunkcenkceshela. Ngokubandakanya ezi zivalo kuyilo kunye nofakelo lwazo, banokuqinisekisa ixesha elide kunye nokuthembeka kweenkqubo zabo zemibhobho kunye nokunkcenkceshela.
