Ponena za dziko la ma valve a gulugufe amalonda, si zipangizo zonse zomwe zimapangidwa mofanana. Pali kusiyana kwakukulu pakati pa njira zopangira ndi zipangizo zomwe zimasintha kwambiri zofunikira ndi luso. Kuti akonzekere bwino kusankha, wogula ayenera kuphunzira ukadaulo ndi kusiyana kwa mtundu uliwonse kuti asankhe bwino chipangizo chake.
1.Kupanga Ma Vavu a Gulugufe
Zipangizo zomangira valavu zimatsimikiza mphamvu zake komanso moyo wake wautali. Mavalavu omwe amapangidwira kuyenda kwambiri, kuthamanga kwambiri, komanso kugwiritsidwa ntchito kwa nthawi yayitali, makamaka m'malo akutali, nthawi zambiri amapangidwa ndi chitsulo cholimba kapena chopangidwa ndi chitsulo cholimba. Mitundu ina yomwe imapangidwira kugwira ntchito yopepuka kapena kugwiritsidwa ntchito kwa nthawi yochepa imapangidwa ndi zinthu monga aloyi wopepuka, aluminiyamu, kapena pulasitiki ya PVC. Mavalavu abwino kwambiri amapangidwa kuti athe kupirira kupsinjika kwakukulu, kunyamula kuyenda kwakukulu kwa zinthu, komanso kukhala olimba komwe kumafunika kuti agwiritsidwe ntchito kwa nthawi yayitali. Pazida zomwe zili m'malo ovuta kufikako kapena zobisika pansi pa nthaka, valavu yokhazikika imafunika. Ndalama zofikira chipangizo chotere kuti chisinthidwe nthawi zambiri zimakhala zazikulu kwambiri, kotero kuyika ndalama mu valavu yapamwamba kwambiri kuyambira pachiyambi ndi chisankho chanzeru.
2.Mapulogalamu Apadera
Kusankha valavu malinga ndi momwe imagwiritsidwira ntchito n'kofunika. Zina ndi zopepuka ndipo zimapangidwa kuti zizigwiritsidwa ntchito poyendetsa madzi ang'onoang'ono kapena poyendetsa mafuta. Ma Aquarium, maiwe, ndi makina opopera ndi zitsanzo zabwino za ntchito zopepuka komanso zosafunikira pa mavalavu a gulugufe.
Ntchito zovuta kwambiri monga mapaipi a gasi, makina oyendera mafuta kapena makina osinthira madzi a mumzinda omwe ali ndi mphamvu zambiri amafunika ma valve apamwamba komanso odalirika okhala ndi nthawi yayitali yogwira ntchito. Zipangizozi zolemera zimayesedwa m'mafakitale kuti ziwone ngati zikugwira ntchito bwino komanso kuti zitsimikizire kudalirika, kuti zikwaniritse ndikupitilira zomwe zimafunikira pantchito yofunika kwambiri.
Mafotokozedwe a wopanga amatha kuwonetsa tsatanetsatane wa mphamvu ya valavu iliyonse. Kusankha valavu yoyenera ntchitoyo ndikofunikira kwambiri kuti igwiritsidwe ntchito kwa nthawi yayitali popanda mwayi wochepa wa kulephera kwa makina.
3.Mulingo Wolondola
Chinthu china chofunikira posankha valavu yogwiritsira ntchito ndi mulingo wolondola womwe wapangidwa mu chipangizocho. Vavu iliyonse ili ndi zofunikira zomwe zimafotokoza kuchuluka kwa kutayikira, ngati kuli koyenera, pamalo otsekedwa, kukula kwa njirayo, kuchuluka kwa madzi komwe kungadutse ikatsegulidwa kwathunthu, komanso kudalirika kwa valavuyo kwa nthawi yayitali. Zomwe zimafotokozanso zimafotokozanso liwiro la ntchito ya valavuyo, yoyenera nthawi yomwe kugwira ntchito nthawi yake ndikofunikira.
4.Zosankha Zowongolera
Chinthu china chofunikira posankha valavu yogwiritsira ntchito ndi njira yowongolera. Mavalavu ena amakhala ndi chogwirira kapena chogwirira, chopangidwa kuti chizisinthidwa ndi manja kuchokera potseguka kupita potsekedwa. Chogwirira nthawi zambiri chimakhala ndi kuzungulira kotala la ulendo kuchokera kumapeto kupita kumapeto, kuti chisinthe mwachangu komanso mosavuta mkhalidwe wa valavu. Ena amapangidwira kuti azigwiritsidwa ntchito okha pogwiritsa ntchito chipangizo chosinthira makina monga solenoid kapena kuyenda kwina kwamakina.
Ma valve apamwamba kwambiri amaphatikizapo makina owongolera magetsi oyendetsedwa ndi mphamvu zonse. Mota iyi imazungulira mwachindunji shaft ya valavu kapena kusuntha lever pogwiritsa ntchito mkono wa actuator. Iliyonse imapereka ulamuliro wonse kuchokera pamalo akutali ndipo ingagwiritsidwe ntchito kusintha kuti iyendetse bwino kayendedwe ka madzi ngati pakufunika.
5.Mphamvu ya Valavu
Chinthu chomaliza posankha valavu ndi mphamvu ya chipangizocho. Izi zikuphatikizapo kuchuluka kwa madzi omwe amadutsa mu valavu panthawi inayake, komanso kuchuluka kwa mphamvu yamkati yomwe valavuyo ingapirire bwino. Pazida zothamanga kwambiri komanso zolemera, valavu yayikulu, yapamwamba imafunika, yokhala ndi kukula koyenera kuti igwirizane ndi dongosolo la chitoliro cholumikizidwa. Onetsetsani kuti mwayang'ana zomwe mukufuna kuti mutsimikizire kuti valavuyo ili ndi mphamvu yokwanira yogwiritsira ntchito.
