Uhla lwethu oluhlukahlukene lweamavalvu e-flange butterflyihlanganisa osayizi abakhulu kusukela ku-DN300 kuya ku-DN1000. Imizimba yamavalvu iyatholakala ngensimbi yekhabhoni kanye nensimbi ephonswe. Izinguqulo eziningi zokuqalisa ezifaka phakathi ukuhlelwa kwesandla, kagesi kanye nokwe-pneumatic zinikezwa ukuze kuhlangatshezwane nezidingo zokusebenza ezahlukahlukene. Lawa mavalvu ezimboni asebenza njengemishini ebalulekile yokuvalwa kwamapayipi kanye nokulawulwa kokulawula ukugoba, futhi asetshenziswa kabanzi ezinhlelweni zokuphakelwa kwamanzi kanye nokukhipha amanzi, ingqalasizinda kamasipala, izitshalo zokwelashwa kwamanzi angcolile, iziteshi zamandla okushisa, izikhungo zokucubungula amakhemikhali kanye nezinye izinhlelo zamapayipi oketshezi zamaphrojekthi aphesheya kwezilwandle emhlabeni jikelele.

Amavalvu e-flange butterfly flange akhethwa kabanzi kumaphrojekthi ahlukahlukene ezimboni ngenxa yokusebenza kahle okuphelele. Uma kuqhathaniswa namavalvu esango namavalvu e-globe anobubanzi obufanayo, lolu chungechunge lwamavalvu luza nobukhulu obufushane bobuso nobuso kanye nesisindo esilula. Lunciphisa ukucindezeleka komthwalo ezakhiweni zokusekela amapayipi futhi lunciphisa izinto zokwakha kanye nezindleko zomsebenzi ngesikhathi sokufakwa endaweni. Izixhumi ze-flange ezijwayelekile zinikeza ukuhambisana okuvelele kwendawo yonke. Ukudilizwa nokugcinwa okuvamile kungaqedwa kalula. Ukuhlolwa nokushintshwa kwamavalvu ngeke kubangele ukuguqulwa kwamapayipi amakhulu, okunciphisa kakhulu isikhathi sokungasebenzi kwemishini futhi kunciphise izindleko zokusebenza zesikhathi eside zamaphrojekthi.

Lolu chungechunge lwamavalvu luhlonyiswe ngezici zobuchwepheshe ezimangalisayo. Luzuza ekwakhiweni kwesakhiwo somugqa ophakathi nendawo, idiski isebenza endaweni ephakathi kuyo yonke imivimbo yokuvula nokuvala. I-torque yokusebenza ihlala iphansi ngakho ukuphathwa ngesandla kungaqedwa kalula. Ifakwe ama-actuator kagesi noma omoya, amavalvu asekela ukuphathwa okuzenzakalelayo okukude, afanela kahle ingqalasizinda yefektri ehlakaniphile kanye nezimo zokusebenza ezinganakiwe. Imizimba yamavalvu ensimbi yekhabhoni inokumelana okunamandla komthelela kanye nomthamo wokuthwala umfutho ophezulu ezimweni zokusebenza ezinzima zezimboni. Imizimba yamavalvu ensimbi ehlanganisiwe ibonisa izakhiwo ezinhle zokulwa nokugqwala futhi ifanelana nezicelo zamanzi zikamasipala eziphakathi nendawo. Izingxenye zokuvala irabha zithola amandla okucindezela alinganayo ukuze kufezwe ukuvalwa okuqinile okuthembekile kanye nokusebenza okungavuzi lutho ngaphansi kwensizakalo yokucindezela okuphansi. I-spectrum yosayizi ophelele esukela ku-DN300 kuya ku-DN1000 isekela ukulethwa kwe-oda lenqwaba ukuze kuhlangatshezwane nezidingo zokuthengwa eziphakathi ezivela kumaphrojekthi amakhulu aphesheya kwezilwandle.

Izinzuzo ezingokoqobo ezihlukile zingabonakala ezinhlelweni zokusebenza zangempela. Uma ivuliwe ngokuphelele, indlela yokugeleza kwangaphakathi ihlala ingaphazanyiswa ngokumelana okuncane koketshezi. Ukulahlekelwa kwengcindezi okuphakathi kugcinwa ezingeni eliphansi, okusiza abasebenzisi bokugcina ukunciphisa ukusetshenziswa kwamandla kohlelo lonke lokujikeleza koketshezi. Izinketho zokusebenzisa eziguquguqukayo zivumela izindawo ezahlukahlukene zesayithi. Ama-actuator esandla kanye nekagesi afaneleka ezindaweni ezingenawo umoya ocindezelwe, kuyilapho ama-actuator omoya ekhethwayo kumapayipi enqubo ezenzakalelayo. Akhiqizwa ngokuhambisana nezindinganiso ze-flange eziqashelwa emhlabeni wonke, ama-valve awadingi ukulungiswa kabusha kwepayipi ngesikhathi sokufakwa kwensimu yaphesheya kwezilwandle. Iyunithi ngayinye ibhekana nokuhlolwa kwengcindezi kanye nokuvalwa ngaphambi kokuthunyelwa. Ukulawulwa kwekhwalithi ngaphambi kokulethwa kunciphisa ngempumelelo izingozi zokuphuka okungenzeka ezindaweni zephrojekthi.

Kwabakhi be-EPC baphesheya kwezilwandle, abahlanganisi bezinhlelo kanye nabalingani bokuhweba bamazwe ngamazwe, ama-valve ethu e-flange butterfly aguquguqukayo aletha inani elilinganiselwe phakathi kwezindleko zokuncintisana, ukusebenza okuzinzile kanye nekhono lokulethwa kwe-bulk-order elithembekile. Akha ikhambi elingabizi kakhulu lokuvala ukugeleza kanye nokuguqulwa ngaphakathi kwamapayipi ezimboni amakhulu. Amaqembu okuthenga angasebenzisa lolu chungechunge lomkhiqizo olulodwa ukuze amboze izimo eziningi zokusebenza, enze lula ukuphathwa kwempahla yezingxenye ezisele futhi athuthukise izinqubo zokunikezela kusukela ekuqaleni kuya ekugcineni. Kungakhathaliseki ukuthi iphrojekthi yakho iphathelene nokwakhiwa kwamanzi kamasipala amasha, ukuthuthukiswa kwamapayipi amanzi angcolile noma ukusethwa kwamapayipi enqubo yemboni esindayo, ama-valve ethu e-flange butterfly ahlukahlukene angafanelana kokubili nemininingwane yakho yobuchwepheshe kanye nezinhloso zezentengiselwano.
