Inzira eshatu z'amabwiriza y'uburyo bwo guhitamo: Ubwoko, amahame n'uburyo bwo guhitamo

Muri NSW Valve, twumva ko kugenzura neza inzira y'amazi ari byo bifasha mu mikorere myiza y'inganda. Valve z'inzira eshatu ni ingenzi cyane mu kugera kuri ubu buyobozi, zitanga uburyo butandukanye bwo kuyobora, kuvanga no guhindura imikorere y'ibikoresho. Iyi nyandiko irambuye isesengura ubwoko, amahame, n'ikoreshwa ry'izi valve z'ingenzi, itanga ubumenyi mu bya tekiniki ukeneye kugira ngo urusheho kunoza sisitemu zawe.

Valve y'inzira eshatu ni iki?

AValve y'inzira eshatuni ubwoko bwa valve y'inganda ifite inzira eshatu mu mubiri wayo. Izi nzira zorohereza guhuza imiyoboro itatu itandukanye, bigatuma valve ibasha gucunga inzira y'amazi hagati yayo. Bitandukanye na valve zoroshye zo kuyifungura no kuyifunga, inshingano nyamukuru ya valve y'inzira eshatu ni uguhindura icyerekezo cy'amazi, kuvanga amazi ava mu masoko abiri, cyangwa kugabanya amazi amwe mo imiyoboro ibiri.

Ubwoko busanzwe buboneka mu miyoboro y'inganda harimoValves z'imipira itatu, Valves zo kugenzura inzira eshatu (cyangwa valves zigenzura), na Valves zo mu bwoko bwa Three Way Globe. Buri bwoko bwakozwe hakoreshejwe uburyo butandukanye bw'imbere—nk'umupira uzenguruka cyangwa igiti cyo guterura—kugira ngo bugere ku musaruro wifuzwa wo kugenzura amazi, bigatuma zikoreshwa mu buryo butandukanye kuva ku gukoresha amazi muri rusange kugeza ku buryo bugoye bwo gukora ibintu.

Ni gute Valve y'Inzira Eshatu Ikora?

Imikorere ya valve y'inzira eshatu ishingiye ku ruhererekane rw'igice cy'imbere (nk'umupira, plagi, cyangwa plagi y'isi) ugereranije n'intebe za valve. Uku kugenda guhindura inzira hagati y'ibyambu bitatu, bigagenzura neza icyerekezo cy'amazi. Hashingiwe ku mikorere yabyo, ahanini bishyirwa mu byiciro bibiri:

Valve yo kuvanga (Imyobo ibiri, Isoko rimwe)

Iyi miterere ifite imiyoboro ibiri yo kwinjira (urugero, A na B) n'umuyoboro umwe wo gusohokera (C). Aho valve iherereye niho hagenga igipimo cy'ibiganiro byinjira biva muri iyo miyoboro ibiri, hanyuma bigavangwa mbere yo gusohokera mu muyoboro (C).

• Urugero: Muri sisitemu za HVAC, Valve yo kugenzura inzira eshatu ikunze gukoreshwa mu kuvanga imigezi y'amazi akonje n'ashyushye kugira ngo haboneke ubushyuhe nyabwo bwo kugenzura ikirere39.
