Eshabhu laseJinbin, inqwaba yezingqwembeamavalvu ebhabhathanesekuqediwe. Kubizwa nangokuthi i-LTivalvu yebhabhathane yesitayela se-lug, enosayizi we-DN400 futhi ifakwe ama-actuator omoya. Manje sebeqalile ukuthutha futhi baya eSaudi Arabia.

I-valve ye-butterfly yohlobo lwe-LT lug iyi-valve evame ukusetshenziswa ezinhlelweni zoketshezi olunomfutho ophakathi nophansi. Izinzuzo zayo eziyinhloko zifaka phakathi ukufakwa okuguquguqukayo, ukuvala okuthembekile kanye nokumelana nokugeleza okuphansi, okwenza ifaneleke ukulawula ukuthuthwa koketshezi ezimweni ezahlukene zokusebenza. Ama-lug kuzo zombili izinhlangothi zomzimba we-valve angalungiswa ngamabhawodi ngaphandle kokuthembela esisindweni se-flange yepayipi, futhi ahambisana nezindinganiso ezahlukene ze-flange njenge-ANSI kanye ne-GB. Lapho kwenziwa ukulungiswa, umzimba we-valve ungahlukaniswa ngokwehlukana ngaphandle kokuthinta uhlelo lwepayipi kanye nepayipi, okuthuthukisa kakhulu ukusebenza kahle kokugcinwa.

Umzimba wevalvu unesakhiwo esincane futhi unesisindo esingu-1/3 kuya ku-1/2 kuphela sevalvu yesango yencazelo efanayo. Indlela yokugeleza ayiphazamiseki futhi iseduze nohlobo oluqondile, olune-coefficient encane yokumelana nokugeleza, okunganciphisa ukusetshenziswa kwamandla kwezokuthutha. Isekela idrayivu yesandla, kagesi noma yomoya, ene-torque encane yokushintsha, okwenza ifanelekele izimo ezinkulu (DN50-DN2000).

I-valve ye-lug butterfly yohlobo lwe-LT isetshenziswa kakhulu kulezi zimo ezilandelayo:

1. Ukuhlinzekwa kwamanzi kanye nokudonswa kwamanzi kanye nokwelashwa kwamanzi: Amanethiwekhi okudonswa kwamanzi kamasipala kanye nokudonswa kwamanzi, izikhungo zokuhlanza indle, imisebenzi yamanzi, esetshenziselwa ukuthutha kanye nokuvimba amanzi ahlanzekile, indle kanye namanzi abuyiselwe. Uhlobo oluthambile oluvalwe lungahlangabezana nezidingo zokuvuza okuphansi futhi lufanele izimo zokugeleza okukhulu.

2. Imboni Ye-Petrochemical kanye Nejwayelekile: Ukuthuthwa kwezinto ezifana namafutha aluhlaza, imikhiqizo kawoyela ocwengekile, izinyibilikisi zamakhemikhali, izixazululo ze-asidi ne-alkali, njll. Uhlobo oluvalwe ngokuqinile lungaphatha izimo zokusebenza zokushisa okuphakathi kanye nengcindezi, futhi indlela yokufaka i-lug ifanele izidingo zokugcinwa njalo kwamapayipi amakhemikhali.

3. Izinhlelo ze-Hvac nezokwakha: Ukujikeleziswa kwamanzi omoya opholile okuphakathi, amanethiwekhi okushisa aphakathi, izinhlelo zamanzi okupholisa ezimbonini. Uhlobo oluvaliwe kahle lunomphumela omuhle wokuvala, lufanelekela izimo zokusebenza eziphansi kanye nezingcindezi eziphansi, kulula ukusebenza futhi lusindisa amandla, futhi lunciphisa izindleko zokusebenza zesistimu.

4. Ukwakha Imikhumbi kanye Nemboni Yensimbi: Izinhlelo zamanzi ze-ballast zomkhumbi, amanzi okupholisa embonini yensimbi, amapayipi ahambisa umoya ocindezelwe. Isakhiwo se-lug sinamandla amakhulu okulwa nokudlidliza futhi sifanelekela izindawo eziyinkimbinkimbi zokufakwa njengemikhumbi enamaqhubu noma izindawo zezimboni.
