Uluhlu lwethu olwahlukeneyo lweiivalvu zebhabhathane ezisicabaIgubungela ubungakanani obukhulu ukusuka kwi-DN300 ukuya kwi-DN1000. Iivalvu ziyafumaneka ngentsimbi yekhabhoni kunye nentsimbi ephosweyo. Iinguqulelo ezininzi zokusebenzisa amandla kuquka uqwalaselo lwezandla, umbane kunye nolwe-pneumatic ziyabonelelwa ukuhlangabezana neemfuno ezahlukeneyo zokusebenza. Ezi valve zemizi-mveliso zisebenza njengezixhobo ezibalulekileyo zokuvala imibhobho kunye nokulawula ukugoba, kwaye zisetyenziswa kakhulu kwiinkqubo zokubonelela ngamanzi kunye nokuhambisa amanzi, iziseko zophuhliso zikamasipala, izityalo zonyango lwamanzi amdaka, izitishi zamandla obushushu, izibonelelo zokucubungula iikhemikhali kunye nezinye iinkqubo zemibhobho yolwelo kwiiprojekthi zehlabathi zaphesheya.

Iivalvu zebhabhathane zeflange yomgca ophakathi zikhethwa kakhulu kwiiprojekthi ezahlukeneyo zoshishino ngenxa yeempawu zokusebenza ezipheleleyo. Xa kuthelekiswa neevalvu zesango kunye neevalvu zeglobe ezinobubanzi obufanayo, olu luhlu lweevalvu luza nobukhulu obufutshane bobuso nobuso kunye nobunzima obulula ngokubanzi. Lunciphisa uxinzelelo lomthwalo kwizakhiwo zenkxaso yepayipi kwaye lunciphisa izixhobo kunye neendleko zomsebenzi ngexesha lokufakelwa kwindawo. Ii-interfaces zeflange eziqhelekileyo zibonelela ngokuhambelana okubalaseleyo kwendawo yonke. Ukuqhaqha kunye nokugcinwa rhoqo kunokugqitywa ngokulula. Ukuhlolwa kunye nokutshintshwa kweevalvu akuyi kubangela utshintsho olukhulu lwepayipi, olunciphisa kakhulu ixesha lokungasebenzi kwezixhobo kwaye lunciphise iindleko zokusebenza zexesha elide kwiiprojekthi.

Olu luhlu lweevalvu luxhotyiswe ngeempawu zobugcisa ezimangalisayo. Ixhamla kulwakhiwo lomgca osembindini, idiski isebenza kwindawo ephakathi kuyo yonke imivumbo yokuvula nokuvala. I-torque yokusebenza ihlala iphantsi ukuze ukuphathwa ngesandla kugqitywe ngokulula. Ifakwe ii-actuators zombane okanye ze-pneumatic, iivalvu zixhasa ulawulo oluzenzekelayo olukude, zilungele ngokupheleleyo iziseko zophuhliso zefektri ezikrelekrele kunye neemeko zokusebenza ezingajongwanga. Imizimba yeevalvu zentsimbi yekhabhoni inokumelana okunamandla kunye nomthamo ophezulu wokuthwala uxinzelelo kwiimeko ezinzima zokusebenza kwemizi-mveliso. Imizimba yeevalvu zesinyithi esityhidiweyo ibonisa iipropati ezilungileyo zokulwa nokugqwala kwaye ifanela ukusetyenziswa kwamanzi kamasipala okuphakathi. Izixhobo zokutywina zerabha zifumana amandla alinganayo oxinzelelo ukuze kufezekiswe ukuvalwa okuqinileyo okuthembekileyo kunye nokusebenza okungekho kuvuza phantsi kwenkonzo yoxinzelelo oluphantsi. I-spectrum yobukhulu obupheleleyo ukusuka kwi-DN300 ukuya kwi-DN1000 ixhasa ukuhanjiswa kwee-odolo ezininzi ukuhlangabezana neemfuno zokuthengwa ezikwindawo enye ezivela kwiiprojekthi ezinkulu zaphesheya.

Iingenelo ezahlukeneyo ezibonakalayo zinokubonakala kwizicelo zehlabathi lokwenyani. Xa ivuliwe ngokupheleleyo, indlela yokuhamba kwangaphakathi ihlala ingaphazanyiswa kukunganyamezelani kolwelo. Ukulahleka koxinzelelo oluphakathi kugcinwa kwinqanaba eliphantsi, nto leyo enceda abasebenzisi bokugqibela ukunciphisa ukusetyenziswa kwamandla kwenkqubo yokujikeleza kolwelo lonke. Iindlela zokusebenzisa eziguquguqukayo zilungele iindawo ezahlukeneyo zesiza. Ii-actuators ezenziwe ngesandla nezombane zilungele iindawo ezingenawo umoya ocinezelweyo, ngelixa ii-actuators zomoya zikhethwa kwiipayipi zenkqubo ezenzekelayo. Zenziwe ngokuhambelana nemigangatho yeflange eyaziwayo kwihlabathi liphela, iivalvu azifuni kulungiswa kwakhona kwepayipi ngexesha lokufakelwa kwentsimi phesheya. Iyunithi nganye ivavanywa uxinzelelo kunye nokutywinwa ngaphambi kokuthunyelwa. Ulawulo lomgangatho ngaphambi kokuhanjiswa lunciphisa ngempumelelo umngcipheko wokuqhekeka kwiindawo zeprojekthi.

Kwabakhi be-EPC baphesheya, abahlanganisi beenkqubo kunye namaqabane orhwebo lwamazwe ngamazwe, iivalvu zethu zeflange butterfly eziguquguqukayo zibonelela ngexabiso elilinganayo phakathi kweendleko ezikhuphisanayo, ukusebenza okuzinzileyo kunye nokukwazi ukuhambisa ii-bulk order okuthembekileyo. Zenza isisombululo esingabizi kakhulu sokuvala ukuhamba kwamanzi kunye nokuguqulwa kwimibhobho yemizi-mveliso emikhulu. Amaqela okuthenga angasebenzisa olu luhlu lwemveliso olunye ukugubungela iimeko ezininzi zokusebenza, ukwenza lula ulawulo lwezinto ezisele kunye nokuphucula iinkqubo zokuhambisa umbane ukusuka ekuqaleni ukuya ekupheleni. Nokuba iprojekthi yakho iphathelele ukwakhiwa kwamanzi amatsha kamasipala, ukuphuculwa kwemibhobho yamanzi amdaka okanye ukuseta imibhobho yemizi-mveliso enzima, iivalvu zethu zeflange butterfly ezahlukeneyo zinokuhambelana neenkcukacha zakho zobugcisa kunye neenjongo zorhwebo.
