E-workshop yaseJinbin, kuhlolwe amavalvu amahlanu amakhulu anobubanzi obuphindwe kabili anobukhulu obuhlukile. Ubukhulu bawo yi-DN2200, kanti imizimba yamavalvu yenziwe ngensimbi ethambile. Ivalvu ngayinye yebhabhathane ifakwe i-actuator kagesi. Njengamanje, lawa mavalvu amaninganaamavalvu ebhabhathanesezihloliwe futhi zamukelwe, futhi zilinde ukupakishwa nokuthunyelwa.

Ngokungafani namavalvu emvemvane ajwayelekile aqondile (lapho isiqu sevalvu sihlangana khona nendawo ephakathi kwepuleti lemvemvane kanye nomzimba wevalvu) noma ivalvu yemvemvane eyodwa eqondile ejiyile (lapho isiqu sevalvu kuphela siphambuka khona phakathi kwepuleti lemvemvane), amavalvu emvemvane ajiyile aphindwe kabili asebenzisa umklamo ojiyile kabili “we-axis yesiqu sevalvu ephambukayo phakathi kwepuleti lemvemvane + i-axis yesiqu sevalvu ephambukayo phakathi nomzimba wevalvu”.

Lesi sakhiwo senza ipuleti levemvane likwazi ukuthintana nesihlalo sevalvu kuphela uma seliseduze nokuvala ngesikhathi senqubo yokuvula nokuvala. Phakathi nesikhathi esisele sokushaya, ipuleti levemvane lihlukaniswe ngokuphelele nesihlalo sevalvu, okunciphisa kakhulu ukungqubuzana nokuguguleka kwendawo yokuvala. Ikakhulukazi ezimweni ezinkulu, lingagwema "ukungqubuzana okunzima" endaweni yokuvala okubangelwa ukuzithwala kwepuleti levemvane noma ingcindezi ephakathi, okwandisa kakhulu impilo yenkonzo yepheya lokuvala, elivame ukuba ngaphezu kuka-30% kunelevali levemvane elilodwa eliyinsimbi ethambile.

Ipuleti le-butterfly le-valve kagesi enobubanzi obukhulu lisebenzisa umklamo ohlelekile. Uma livuliwe ngokuphelele, ipuleti le-butterfly linendawo encane yokuvimba ye-medium kanye ne-coefficient yokumelana nokugeleza okuphansi, okunganciphisa ukulahleka kwamandla kohlelo lwepayipi. Kumapayipi amakhulu anobubanzi obungu-DN1000 noma ngaphezulu (njengemigqa yamanzi yasemadolobheni kanye nezinhlelo zamanzi ezijikeleza iziteshi zamandla), ukusetshenziswa kwamandla kwesethi yephampu kusindiswe kakhulu.

Izinto zomzimba we-valve zingakhethwa kusuka ku-ductile iron (yamanzi kamasipala), insimbi yekhabhoni (yamafutha ezimboni), noma insimbi engagqwali (yezinto ezigqwali) ngokusekelwe ezicini zento ephakathi nendawo. Ubuso bepuleti le-butterfly bungashintshwa nge-spray-weld ngesendlalelo esingagugi (njenge-tungsten carbide), esingamelana nokuguguleka kwezinto ezingaphakathi nendawo ezinenani elincane lezinhlayiya (njengesihlabathi kanye ne-slag). Ukuze kuthuthwe uketshezi oluqukethe ukungcola okufana nendle kanye ne-ash slurry, impilo yalo yokusebenza iphindwe kabili kuya kathathu kune-valve evamile ye-butterfly.

Ububanzi obukhuluivalvu yebhabhathane ephindwe kabili, ngokusebenzisa ukusungula izinto ezintsha, kulinganisele ukulawula ukugeleza, ukusebenza kokuvala kanye nokuphila kokusebenza kwamapayipi amakhulu. Sekuyisisombululo esisebenzayo sokufaka esikhundleni samavalvu esango lendabuko namavalvu ebhola ezinhlelweni ezisebenza kakhulu neziyinkimbinkimbi emkhakheni kamasipala, kagesi, wokulondolozwa kwamanzi, wezimboni nakwezinye izindawo. Ifaneleka kakhulu ezimweni zokusebenza zesikhathi eside ezizwela ukusetshenziswa kwamandla kanye nezindleko zokulungisa.
