Valavu ndi gawo lowongolera lomwe limagwiritsa ntchito gawo losuntha kuti litsegule, kutseka, kapena kutsekereza pang'ono malo amodzi kapena angapo kuti kutuluka kwamadzi, mpweya, kapena kutuluka kwina kwa mpweya kapena zinthu zambiri zitha kutuluka, kutsekedwa, kapena kulamulidwa chipangizo;amatanthauzanso pakati pa valve, gawo losuntha la chipangizochi.
Pali mitundu yambiri ya ma valve ndi ntchito zambiri zomwe zimagwiritsidwa ntchito, kuyambira pamagetsi pa moyo wa tsiku ndi tsiku, ma valve otsekemera ophikira ophikira, kuwongolera ma valve, ma valve amadzimadzi, ma valve a gasi, etc.
Mitundu ya ma valve ndi awa:
Chongani valavu Solenoid valavu yachitetezo Vavu yopumira Vavu yopumira valavu yowongolera valavu ya sludge valavu ya diaphragm Diverter valavu yotulutsa valavu yotulutsa Chipata valavu Gulugufe vavu Gulugufe Vavu ya msampha Vavu yowongolera Pulagi Vavu yamaso Vavu yamaso opanga atha kupanga ndi kupanga mavavu osiyanasiyana molingana ndi miyezo yapadziko lonse ya ISO, miyezo ya DIN yaku Germany, miyezo ya AWWA yaku America ndi miyezo ina yapadziko lonse lapansi, ndipo zopangidwa ndi opanga ena zafika pamlingo wapamwamba wapadziko lonse lapansi.
Valavu imatha kugwiritsidwa ntchito pamanja kapena ndi gudumu lamanja, chogwirira kapena chopondapo, komanso imatha kuwongoleredwa kuti isinthe kupanikizika, kutentha ndi kuthamanga kwa sing'anga yamadzimadzi.Mavavu amatha kugwira ntchito mosalekeza kapena mobwerezabwereza pazosinthazi, monga mavavu otetezera omwe amaikidwa m'makina amadzi otentha kapena ma boilers a nthunzi.
M'machitidwe ovuta kwambiri owongolera ma valve odziwongolera amagwiritsidwa ntchito potengera zosowa zakunja (ie kusintha kayendedwe ka chitoliro kupita kumalo osinthika).Valve yodziwongolera yokhayokhayo sifunikira kugwiritsa ntchito pamanja, ndipo malinga ndi kuyika kwake ndi kukhazikitsa, valavu imatha kuwongolera molondola zofunikira zosiyanasiyana za sing'anga yamadzimadzi.
Mavavu wamba akhoza kugawidwa mu:
Valve yotseka:makamaka ntchito kudula ndi kulumikiza sing'anga madzimadzi, kuphatikizapo valavu pachipata, valavu globe, diaphragm valavu, valavu pulagi, valavu mpira, valavu gulugufe, etc.
Valve yowongolera: makamaka ntchito kusintha otaya, kuthamanga, kutentha, etc. wa sing'anga madzimadzi, kuphatikizapo valavu yowongolera, valavu throttle, valavu kuchepetsa kuthamanga, valavu thermostatic, etc.
Chongani valve:makamaka ntchito kuteteza kumbuyo kutuluka kwa sing'anga madzimadzi.
Diverter valve:makamaka ntchito kugawa, kulekanitsa ndi kusakaniza zamadzimadzi TV, kuphatikizapo slide valavu, Mipikisano doko valavu, nthunzi msampha, etc.
Valve chitetezo: makamaka ntchito chitetezo chitetezo kupewa kuwonongeka kwa boilers, zotengera kuthamanga kapena mapaipi.
Mavavu amagwiritsidwa ntchito makamaka m'mafakitale, zankhondo, zamalonda, zogona, zoyendera ndi mafakitale monga mafuta ndi gasi, kupanga magetsi, migodi, maukonde amadzi, kuyeretsa zimbudzi ndi kupanga mankhwala.Ndipo amagwiritsidwa ntchito kwambiri pakupanga mafakitale ndi zaulimi komanso moyo watsiku ndi tsiku.
