Kwi-workshop yaseJinbin, iqela leengxowaiivalvu zebhabhathaneigqityiwe. Ikwabizwa ngokuba yi-LTivalvu yebhabhathane yesitayile se-lug, enobukhulu be-DN400 kwaye ixhotyiswe ngee-actuators zomoya. Ngoku sele beqalile ukuthutha kwaye baya eSaudi Arabia.

Ivalvu yebhabhathane yohlobo lwe-LT lug yivalvu esetyenziswa rhoqo kwiinkqubo zolwelo oluphakathi noluphantsi koxinzelelo. Iingenelo zayo eziphambili ziquka ukufakwa okuguquguqukayo, ukutywinwa okuthembekileyo kunye nokumelana nokuhamba kwamanzi okuphantsi, okwenza ukuba ifaneleke kulawulo lokuthuthwa kolwelo kwiimeko ezahlukeneyo zokusebenza. Iilug kuzo zombini iziphelo zomzimba wevalvu zinokulungiswa ngeebholiti ngaphandle kokuxhomekeka kubunzima beflange yombhobho, kwaye ziyahambelana nemigangatho eyahlukeneyo yeflange efana ne-ANSI kunye ne-GB. Xa kusenziwa ulondolozo, umzimba wevalvu unokuqhekeka ngokwahlukeneyo ngaphandle kokuchaphazela inkqubo yombhobho kunye nombhobho, nto leyo ephucula kakhulu ukusebenza kakuhle kolondolozo.

Umzimba wevalvu unesakhiwo esincinci kwaye unobunzima obuyi-1/3 ukuya kwi-1/2 kuphela yevalvu yesango yendlela efanayo. Indlela yokuhamba ayithintelwanga kwaye ikufutshane nohlobo oluthe tye, kunye ne-coefficient encinci yokumelana nokuhamba, enokunciphisa ukusetyenziswa kwamandla ekuthuthweni. Ixhasa i-drive yesandla, yombane okanye ye-pneumatic, kunye ne-torque encinci yokutshintsha, okwenza ukuba ifaneleke kwiimeko ezinkulu (DN50-DN2000).

Ivalvu yebhabhathane yohlobo lwe-LT lug isetyenziswa kakhulu kwezi meko zilandelayo:

1. Ubonelelo lwamanzi kunye nokucocwa kwamanzi: Iinethiwekhi zobonelelo lwamanzi kunye nokucocwa kwamanzi zikamasipala, izitishi zokucoca amanzi amdaka, imisebenzi yamanzi, esetyenziselwa ukuthutha kunye nokuthintela amanzi acocekileyo, amanzi amdaka kunye namanzi abuyiselweyo. Uhlobo oluthambileyo olutywiniweyo lunokuhlangabezana neemfuno eziphantsi zokuvuza kwaye lufanelekile kwiimeko zokuhamba kwamanzi amakhulu.

2. Ishishini lePetrochemical kunye neLizwe Jikelele: Ukuthuthwa kwezinto ezifana neoyile ekrwada, iimveliso zeoyile ecociweyo, izinyibilikisi zeekhemikhali, izisombululo ze-asidi kunye ne-alkali, njl. Uhlobo oluvalwe ngokuqinileyo lunokumelana nobushushu obuphakathi kunye neemeko zokusebenza zoxinzelelo, kwaye indlela yokufaka i-lug ifanelekile kwiimfuno zokugcinwa rhoqo kwemibhobho yeekhemikhali.

3. Iinkqubo zeHvac kunye nezakhiwo: Ukujikeleza kwamanzi omoya opholileyo ophakathi, iinethiwekhi zokufudumeza ezihlanganisiweyo, iinkqubo zamanzi okupholisa kwimizi-mveliso. Uhlobo olutywiniweyo oluthambileyo lunesiphumo esihle sokutywina, lufanelekile kwiimeko zokusebenza ezinobushushu obuphantsi kunye noxinzelelo oluphantsi, kulula ukuyisebenzisa kwaye igcina umbane, kwaye inciphisa iindleko zokusebenza kwenkqubo.

4. Ulwakhiwo lweenqanawa kunye noShishino lweMetallurgical: Iinkqubo zamanzi ze-ballast zeenqanawa, amanzi okupholisa kwishishini le-metallurgical, imibhobho ehambisa umoya ocinezelweyo. Isakhiwo se-lug sinamandla okumelana nokungcangcazela kwaye sifanelekile kwiindawo ezintsonkothileyo zokufakelwa ezifana neenqanawa ezinamaqhuma okanye iindawo zoshishino.
