Umhlahlandlela Wamavalvu Ezindlela Ezintathu: Izinhlobo, Izimiso Nokukhetha

Kwa-NSW Valve, siyaqonda ukuthi ukulawulwa kokugeleza okunembile kuyigazi lokuphila kwemisebenzi yezimboni ephumelelayo. Amavalvu anezindlela ezintathu ayizingxenye ezibalulekile ekufezeni lokhu kulawula, anikeza ukuguquguquka okungenakuqhathaniswa ekuqondiseni, ekuxubeni, nasekuphambukiseni imidiya yenqubo. Lo mhlahlandlela oqondile uhlola izinhlobo, izimiso, kanye nokusetshenziswa kwala mavalvu abalulekile, okunikeza ukuqonda kobuchwepheshe okudingayo ukuze uthuthukise izinhlelo zakho.

Iyini i-Three Way Valve?

AI-Valve Yezindlela Ezintathuuhlobo lwevalvu yezimboni olunezimbobo ezintathu emzimbeni walo. Lawa machweba enza kube lula ukuxhumana kwamapayipi amathathu ahlukene, okuvumela ivalvu ukuthi ilawule indlela yokugeleza phakathi kwawo. Ngokungafani namavalvu alula okuvula/ukuvala, umsebenzi oyinhloko wevalvu enezindlela ezintathu ukushintsha indlela yokugeleza, ukuxuba ukugeleza okuvela emithonjeni emibili, noma ukuhlukanisa ukugeleza okukodwa kube yimifudlana emibili.

Izinhlobo ezivamile ezitholakala ezinhlelweni zamapayipi ezimboni zifaka phakathiAmavalvu Ebhola Ezindlela Ezintathu, Amavalvu Okulawula Ezindlela Ezintathu (noma amavalvu okulawula), kanye namavalvu eGlobe Ezindlela Ezintathu. Uhlobo ngalunye lwakhiwe ngezindlela zangaphakathi ezihlukile—njengebhola elijikelezayo noma isiqu sokuphakamisa—ukufeza umsebenzi wokulawula ukugeleza ofiselekayo, okubenza bafanelekele izinhlelo eziningi zokusebenza kusukela ekufakweni kwamapayipi okuvamile kuya ekuzenzekeleni kwenqubo eyinkimbinkimbi.

Isebenza Kanjani Ivalvu Yezindlela Ezintathu?

Ukusebenza kwevalvu enezindlela ezintathu kuncike ekuhambeni kwengxenye yangaphakathi (njengebhola, ipulaki, noma ipulaki yeglobe) uma kuqhathaniswa nezihlalo zamavalvu. Lokhu kuhamba kushintsha izindlela eziphakathi kwamachweba amathathu, kulawula ngempumelelo isiqondiso soketshezi. Ngokusekelwe emsebenzini wazo, zihlukaniswe kakhulu ngezinhlobo ezimbili:

I-Mixing Valve (Izingenelo Ezimbili, I-Outlet Eyodwa)

Lokhu kulungiselelwa kunezimbobo ezimbili zokungena (isb., A no-B) kanye nembobo eyodwa yokungena evamile (C). Indawo ye-valve core ilawula isilinganiso semidiya engena kusuka ezimbobeni ezimbili zokungena, bese ixutshwa ngaphambi kokuba ikhishwe esimbozweni (C).

• Isibonelo: Ezinhlelweni ze-HVAC, i-Three Way Control Valve ivame ukusetshenziswa ukuhlanganisa imifudlana yamanzi abandayo nashisayo ukuze kufezwe izinga lokushisa eliqondile lokulawula isimo sezulu39.

I-Valve Yokujika (Ukungena Okukodwa, Izindawo Zokuphuma Ezimbili)

Lokhu kulungiselelwa kunembobo eyodwa evamile yokungena (A) kanye namambobo amabili okuphuma (B no-C). Ukunyakaza kwe-valve core kuqondisa ukugeleza okungenayo kusuka ku-inlet eyodwa (A) kuya kwenye yezindawo ezimbili zokuphuma (B noma C) noma kuyihlukanisa ngokulinganayo phakathi kokubili.

• Isibonelo: Ekucubungulweni kwamakhemikhali, ivalvu yokuphambukisa ingasabalalisa umfudlana wezinto ezingavuthiwe phakathi kwemikhumbi emibili ehlukene ye-reactor noma imigqa yokucubungula.

Imisebenzi Eyinhloko Yama-Valve Ezindlela Ezintathu

Inhloso eyinhloko yevalvu enezindlela ezintathu ukushintsha izindlela zokugeleza koketshezi ngokuhamba kwendlela yangaphakathi. Ukusebenza kwayo kungafingqwa ngezindlela ezimbili eziyinhloko:

• Ukuxuba (Ukuhlanganisa Ukugeleza): Ukuhlanganisa imifudlana emibili yoketshezi engenayo ibe yindawo eyodwa yokukhipha amanzi. Lokhu kulungele ukulawulwa kwezinga lokushisa noma izimo zokulinganisa amakhemikhali eziqondile lapho kudingeka khona ukuhlanganiswa kwemidiya emibili.

• Ukuphambukisa (Ukugeleza Okuhlukanayo): Ukuhlukanisa umfudlana owodwa woketshezi olungenayo phakathi kwezindawo ezimbili zokukhipha amanzi. Lokhu kuvame ukusetshenziselwa ukulawula i-bypass, ukuhlukaniswa kwesistimu, noma ukushintsha izinqubo, ukuqinisekisa ukugeleza okuqhubekayo ohlelweni ngesikhathi sokulungiswa noma izinguquko zokusebenza.

Amavalvu Ezindlela Ezintathu vs. Amavalvu Ezindlela Ezintathu: Umehluko Oyisisekelo

Umehluko obonakalayo obonakala kakhulu yi-extra flow port. I-valve ejwayelekile enezindlela ezimbili inokungena okukodwa kanye ne-outlet eyodwa, esebenza ngokuyinhloko njengedivayisi yokuvula/yokuvala noma elula yokulawula indlela eyodwa yokugeleza.

I-Three Way Valve, ene-port yayo eyengeziwe (evame ukubizwa ngokuthi i-diverting port C), yenzelwe ngqo ukushintsha indlela yokugeleza. Umsebenzi oyisisekelo uhilela imidiya engena nge-port A. Kuye ngokuthi i-valve ikuphi, ukugeleza kuqondiswa ku-port B noma ku-port C. Uma i-valve ivaliwe, ingavala ngokuphelele ukugeleza. Leli khono lokulawula eliqondisayo liwumsebenzi ojwayelekile wama-valve angenawo.

Izinhlobo Zama-Valve Ezindlela Ezintathu: Ukuhlukaniswa Okuningiliziwe

Amavalvu anezindlela ezintathu angahlukaniswa ngokwedizayini yawo, izinto zokwakha, kanye nendlela yokusebenza.
