Kwi-workshop yaseJinbin, iivalvu ezintlanu ezinkulu zebhabhathane eziphindwe kabini ezingaqhelekanga zihlolwe. Ubukhulu bazo yi-DN2200, kwaye imizimba yeevalvu yenziwe ngentsimbi ethambileyo. Ivalvu nganye yebhabhathane ixhotyiswe nge-actuator yombane. Okwangoku, ezi zininziiivalvu zebhabhathanezihlolwe kwaye zamkelwe, kwaye zilinde ukupakishwa nokuthunyelwa.

Ngokungafaniyo neevalvu zebhabhathane eziziiconcentric zemveli (apho isiqu sevalvu sidibana nombindi wepleyiti yebhabhathane kunye nomzimba wevalvu) okanye ivalvu yebhabhathane enye engaqhelekanga (apho isiqu sevalvu kuphela siphuma embindini wepleyiti yebhabhathane), iivalvu zebhabhathane eziziiconcentric ezimbini zisebenzisa uyilo oluziiconcentric oluziiconcentric oluziiconcentric ezimbini "lwe-valve stem axis ephuma embindini wepleyiti yebhabhathane + i-valve stem axis ephuma embindini womzimba wevalvu".

Olu lwakhiwo lwenza ukuba ipleyiti yebhabhathane idibane kuphela nesihlalo sevalvu xa sele isondele ekuvaleni ngexesha lenkqubo yokuvula nokuvala. Ngexesha lokubetha, ipleyiti yebhabhathane yahlulwe ngokupheleleyo kwisihlalo sevalvu, nto leyo enciphisa kakhulu ukungqubana kunye nokuguguleka komphezulu wokutywina. Ingakumbi kwiimeko ezinkulu, inokukuphepha "ukungqubana okunzima" kumphezulu wokutywina okubangelwa kukuzithwala kwepleyiti yebhabhathane okanye uxinzelelo oluphakathi, nto leyo eyandisa kakhulu ubomi benkonzo yesitywina, esihlala singaphezulu kwama-30% kunobo beevalvu zebhabhathane zentsimbi enye.

Ipleyiti yebhabhathane yevalvu yebhabhathane yombane enobubanzi obukhulu isebenzisa uyilo olucwangcisiweyo. Xa ivuliwe ngokupheleleyo, ipleyiti yebhabhathane inendawo encinci yokuvimba i-medium kunye ne-coefficient ephantsi yokumelana nokuhamba kwamanzi, enokunciphisa ukulahleka kwamandla kwenkqubo yepayipi. Kwimibhobho emikhulu enobubanzi be-DN1000 nangaphezulu (njengemigca yamanzi asezidolophini kunye neenkqubo zamanzi ezijikeleza izityalo zamandla), ukusetyenziswa kwamandla kweseti yepompo kugcinwe kakhulu.

Izinto zomzimba wevalvu zingakhethwa kwintsimbi ethambileyo (yamanzi kamasipala), intsimbi yekhabhoni (yeoyile yemizi-mveliso), okanye intsimbi engatyiwayo (yezinto ezibangela ukubola) ngokusekelwe kwiimpawu zesixhobo. Umphezulu wepleyiti yebhabhathane unokutshizwa nge-spray-welded ngomaleko onganyangekiyo (njenge-tungsten carbide), onokumelana nokukhukuliseka kwezixhobo eziqulethe inani elincinci lamasuntswana (njengesanti kunye ne-slag). Ukuhambisa ulwelo oluqulethe ukungcola okufana nelindle kunye ne-ash slurry, ubomi balo benkonzo buphindwe kabini ukuya kathathu kuneevalvu zebhabhathane eziqhelekileyo.

Ububanzi obukhuluivalvu yebhabhathane engaqhelekanga kabini, ngokusebenzisa uyilo olutsha lwesakhiwo, ilungelelanise ulawulo lokuhamba kwamanzi, ukusebenza kokutywina kunye nobomi bokusebenza kwemibhobho emikhulu. Ibe sisisombululo esisebenzayo sokutshintsha iivalvu zesango zemveli kunye neevalvu zebhola kwiinkqubo eziphakathi ezihamba amanzi aphezulu nezintsonkothileyo kumasipala, umbane, ulondolozo lwamanzi, imboni kunye neminye imimandla. Ifanelekile ngokukodwa kwiimeko zokusebenza kwexesha elide ezinobuthathaka kukusetyenziswa kwamandla kunye neendleko zokugcina.
