Eshabhu ye-Jinbin, inqwaba yezikhwamaizivalo uvemvanesekuqediwe. Ibizwa nangokuthi i-LTi-lug style butterfly valve, enosayizi we-DN400 futhi ifakwe ama-actuator womoya. Manje sebeqalile ezokuthutha futhi balibangise eSaudi Arabia.

Ivalve yohlobo lwe-butterfly ye-LT lug iyi-valve evame ukusetshenziswa ezinhlelweni zamanzi ezinomfutho ophakathi nendawo. Izinzuzo zayo eziyinhloko zihlanganisa ukufakwa okuguquguqukayo, ukubekwa uphawu okuthembekile kanye nokumelana nokugeleza okuphansi, okuyenza ifanelekele ukulawula ukuthuthwa kwamanzi ezimeni ezihlukahlukene zokusebenza. Ama-lugs emikhawulweni yomibili ye-valve yomzimba angalungiswa ngamabhothi ngaphandle kokuncika esisindweni se-flange yepayipi, futhi ahambisana namazinga ahlukahlukene e-flange afana ne-ANSI ne-GB. Lapho kwenziwa ukunakekelwa, umzimba we-valve ungahlakazwa ngokuhlukana ngaphandle kokuthinta ipayipi kanye nesistimu yepayipi, okuthuthukisa kakhulu ukusebenza kahle kokulungisa.

Umzimba we-valve unesakhiwo esihlangene futhi unesisindo esingu-1/3 kuya ku-1/2 kuphela we-valve yesango yokucaciswa okufanayo. Umzila wokugeleza awuvimbeli futhi usondele kuhlobo oluqondile, olune-coefficient yokumelana nokugeleza okuncane, okunganciphisa ukusetshenziswa kwamandla okuthutha. Isekela idrayivu yezandla, kagesi noma ye-pneumatic, ene-torque encane yokushintsha, iyenze ifaneleke izimo ezinobubanzi obukhulu (DN50-DN2000).

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

1. Ukuhlinzekwa kwamanzi kanye nokukhipha amanzi kanye nokuhlanzwa kwamanzi: Inethiwekhi kamasipala yokuphakela amanzi kanye nemisele, izizinda zokukhuculula indle, izinsiza zamanzi, ezisetshenziselwa ukuthutha nokucabela amanzi ahlanzekile, indle kanye namanzi abuyiselwe kabusha. Uhlobo oluvalwe ngokuthambile lungahlangabezana nezidingo eziphansi zokuvuza futhi lufanele izimo zokugeleza okukhulu.

2.Imboni ye-Petrochemical kanye ne-General: Ukuthuthwa kwemidiya efana nowoyela ongahluziwe, imikhiqizo kawoyela ocolisisiwe, izinyibilikisi zamakhemikhali, izixazululo ze-asidi ne-alkali, njll. Uhlobo oluvalwe ngokuqinile lungakwazi ukuphatha izinga lokushisa eliphakathi nendawo nokucindezela izimo zokusebenza, futhi indlela yokufaka i-lug ifanele izidingo zokugcinwa njalo kwamapayipi amakhemikhali.

I-3.Hvac kanye nezinhlelo zokwakha: Ukujikeleza kwamanzi omoya ophakathi nendawo, amanethiwekhi okushisa aphakathi nendawo, izinhlelo zamanzi zokupholisa zezimboni. Uhlobo olufakwe uphawu oluthambile lunomphumela omuhle wokuvala, lufanele izimo zokusebenza ezisezingeni eliphansi neziphansi, kulula ukusebenza futhi zonga amandla, futhi kunciphisa izindleko zokusebenza zesistimu.

I-4.Imboni Yokwakha Umkhumbi kanye Nensimbi: Izinhlelo zamanzi ze-ballast zomkhumbi, amanzi okupholisa embonini ye-metallurgical, amapayipi omoya acindezelweyo. Isakhiwo se-lug sinokusebenza okuqinile kokumelana nokudlidliza futhi sifanele izindawo zokufaka eziyinkimbinkimbi njengemikhumbi enamaphutha noma iziza zezimboni.
