Namuhla,amavalvu ebhabhathane angavamileI-DN1000 kanye ne-DN1200 zefektri yethu sezipakishiwe futhi sezilungele ukulethwa. Leli qoqo lama-valve e-butterfly lizothunyelwa eRussia.

Amavalvu ebhabhathane aphindwe kabili kanye namavalvu ebhabhathane avamile ayizinhlobo zamavalvu ezivamile, futhi ahlukile ngesakhiwo kanye nokusebenza. Ivalvu yebhabhathane ephindwe kabili iwuhlobo lokusebenza okuphezulu.ivalvu yebhabhathane elijiyile, ithuthukiswa ngesisekelo se-valve eyodwa ye-butterfly engavamile, futhi i-valve evamile ye-butterfly ivame ukubhekisela ku-valve ye-butterfly ethambile yomugqa ophakathi.

Isakhiwo se-eccentric ephindwe kabilii-valve yebhabhathane yentengoIbonakala nge-axis yayo yesiqu ephambuka enkabeni yepuleti lebhabhathane kanye nasenkabeni yomzimba. Lo mklamo wenza i-valve ngemva kokuvulwa, i-disc ingasuswa ngokushesha esihlalweni, isuse kakhulu ukukhishwa okungadingekile ngokweqile kanye nokuklwebheka phakathi kwe-disc nesihlalo, ngaleyo ndlela inciphise ukungqubuzana nokuguguleka, futhi ithuthukise ukusebenza kokuvala kanye nokuphila kwesevisi ye-valve.

Isakhiwo se-valve evamile ye-offset butterfly silula kakhulu, i-axis yesiqu, ipuleti le-butterfly kanye nomzimba kusendaweni efanayo, futhi izivalo ezithambile zivame ukusetshenziswa, njengerabha noma i-polytetrafluoroethylene nezinye izinto, ezifanele ukusetshenziswa endaweni yokushisa evamile kanye nendawo ephansi yokucindezela futhi zisebenza kahle ekuvaleni.

Ivalvu yebhabhathane ephindwe kabili isebenza ngendlela efanayo nevalvu yebhabhathane eyodwa engavamile, kodwa ngenxa yomklamo wayo ophindwe kabili, isebenza kangcono ekuvaleni kanye nokungqubuzana nokuguguleka okuphansi. Umgomo osebenzayo wevalvu yebhabhathane evamile eqhutshwayo ukulawula ukugeleza koketshezi ngokujikeleza ipuleti yevalvu, kanye nesiqondiso sokujikelezisa sepuleti yevalvu sinquma isiqondiso sokugeleza koketshezi. Ngenxa yesakhiwo sayo esilula, ngesikhathi senqubo yokuvula nokuvala ivalvu yebhabhathane evamile engamasentimitha angu-6, ipuleti yebhabhathane kanye nesihlalo kuhlala kusesimweni sokucindezelwa nokukhuhla, okungaholela ekungqubuzaneni nasekugugeni okukhulu.

I-valve yebhabhathane engavamile kabili ifanelekela izitshalo zamanzi, izitshalo zikagesi, ukuncibilikisa insimbi, imboni yamakhemikhali, ubunjiniyela bemithombo yamanzi, ukwakhiwa kwezikhungo zemvelo kanye nezinye izinhlelo zokukhipha amanzi, ikakhulukazi ezifanele ukusetshenziswa kwamapayipi amanzi njengemishini yokulawula nokuvala.
