Bupanduluzi:

Ivalvu yakugwisya muya uufwambaana kapati ilaswaanganizyigwa azibeela zyobile zya valve ya muya uujisi nguzu kapati alimwi a valve yakunjila akugusya muya uutontola kapati, ilijisi zyoonse zyobile milimo yakugwisya muya alimwi akunjizya muya.
Ivaluvu lyakugwisya muya lya diaphragm lyamuwo mupati lilagwisya muya muniini uubungene mumupayipi eelyo payipi noili munsi lyamuwo.
Ivalvu yakunjizya akugusya muuya uuzwa mumubili taikonzyi buyo kugwisya muuya mumupayipi eelyo mupayipi uutakwe chintu nowazula maanzi, pesi alubo aawo mupayipi nuuzwide maanzi naakuti muya uutali kabotu wachitika, mbuli muchiimo chakwaandaanya maanzi, uyoojula mpawo unjile mumupayipi kuchitila kuti muya uutali kabotu ugwisye.

Imwi milimu mipati ya valve yakugusya muya ngwakugwisya muya uujatikizyidwe muchibelesyo. Eelyo maanzi naanjila mumapaipi, muuya ulakonzya kujatikizyigwa mumasena aali atala, mbuli mumasena aali atala, mumasena aali atalaa malundu. Aawo maanzi naainda mumapayipi, muuya ulakonzya kuyoboloka akupanga zibbeeke zyamuuya, zikonzya kuleta kucheya kwakubeleka kabotu akuyungizya nguzu.

Mavalvu aakugwisya muuya, mbuli TWS Valve's aambizivwunisyo zya bbatterfly zikkede a raba, alimwi zilagwasya kapati mukubamba kabotu alimwi akubeleka kabotu kwamapaipi alimwi anzila zinyamuna maanzi. Inguzu zyabo zyakugwisya muya uujatikizyidwe akukwabilila bukkale bwakubula muya kupa kuti nzila ibeleke kabotu, ikukwabilila kunyongana akunyonyooka. Kwiinda mukumvwisisisya mbociyandika mavalvu aakugusya muya akubweza ntaamu zyeelede zyakubikka akubamba, basikubelesya nzila eeyi balakonzya kusinizya kuti mapaipi aabo azibelesyo zyabo zilapona kwachiindi chilamfu akusyomeka.

Ziyandikana mukubeleka:

Ivalvu yakugusya muya iijisi nguzu zyaansi (float + float type) mulyango mupati wakugusya muya ulasinizya kuti muya unjile akuzwa amweelwe mupati aawo muya uuzwa mujulu, nikuba muya uuzwa muchiindi chifwiifwi uusanganizidwe amaanzi, Taukonzyi kujala muya wakugusya muuya kakuchili chiindi. Mulyango wamuwo uyoojalwa biyo kuti muya wazwa.
Kufumbwa chiindi, kufwumbwa buyo kuti muya wamukati kachibelesyo kauli munsi-munsi anguzu zyamumulengalenga, mbuli chitondeezyo, aawo kwaandaana kwamaanzi nokwachitika, vvalavu lyamuwo liyoojaluka mpawo-mpawo kuti muya unjile muchibelesyo kuchitila kutabilila kupanga busena bwamuwo. Aawo awo, kunjila muuya muchiindi cheelede aawo nzila noili mukugusya muya kulakonzya kufwambaanya kugwisya muya. Kujulu lya vvalavu yakugusya muya kuli chintu chikwabilila kuti muya uzwe kabotu, eecho chikonzya kulesya kuchincha kwa muya naakuti zimwi zintu zikonzya kunyonyoona.
Ivalvu yakugwisya muya uujisi nguzu kapati ilakonzya kugwisya muya uubungene mumasena aali atala kapati munzila eeyi muciindi eelyo nzila noili munsi lyanguzu kutegwa kutabi zintu zitobela zikonzya kunyonganya nzila eeyi: kujala muya naa kuvwumbililwa kwamuya.
Kuyungizya kusweekelwa mutwe wachibelesyo kuchelesya kweenda kwamaanzi mpawo nikuba muzyiimo zikatazya loko kulakonzya kuleta kunyongana kwakuzwa kwamaanzi. Kuyungizya kunyonyooka kwa cavitation, kufwambaanya kubola kwazibeela zyabutale, kuyungizya kucinca-cinca kwanguzu mubweende, kuyungizya kulubizya kwazibelesyo zyakupima, alimwi akupwasuka kwamuwo. Kusumpula nzila zyakubelesya maanzi mumapaipi.

Njiisyo yakubeleka:

Nzila yakubeleka ya vvalavu yamuwo iisanganizidwe aawo payipi iitakwe chintu niyazula maanzi:
1. Kogwisya muya mumupayipi kuchitila kuti kuzuzya maanzi kweende kabotu.
2. Muya uuli mumupayipi nuuzwa, maanzi alanjila mumulyango wakunjizya akugusya muya, mpawo lwizi lulasumpulwa abwaanda bwakutanta kuchitila kuti ijale nzila yakunjizya akugusya muya.
3. Muya uuzwa mumaanzi muchiindi chakutola maanzi uyobungikwa aawo mpaali atala kapati, nkokuti, mumulyango wamuwo kuti ubweze busena bwamaanzi aakusaanguna mumubili wamulyango.
4. Mukuyoboloka kwamuya, mweelwe wamaanzi mubbola lyakugusya muuya lilaseluka, mpawo bbola lyamaanzi alyalo lilaseluka, akukwela diaphragm kuti ijale, kujalula muya wakugusya muuya, mpawo akugusya muuya.
5. Nikwazwa muuya, maanzi alanjila mumulyango wakugusya muya uujisi nguzu kapati alimwi, akuzuzya bbola lileenda, akujala mulyango wakugusya muya.
Eelyo nzila eeyi noili mukubeleka, ntaamu zili atala aawa zyotatwe, zyone, zyosanwe ziyoozumanana kweenda
Nzila yakubeleka ya valve yamuya uusanganizidwe aawo muya uuli mukati kamuwo nuuli munsi-munsi a muya uuzwa mumulengalenga (kupa muya uutali kabotu):
1. Ibbola litantamuka lya vvalavu lyakunjila akugusya muya uuzwa mumubili lilafwambaana kudonkola kujalula nzila zyakunjizya akugusya muya.
2. Muya ulanjila munzila kuzwa aawa kuchitila kuti ugwisye muya uutali kabotu akukwabilila nzila.
