Ivalve yebhola licandelo eliphambili kuyo nayiphi na inkqubo yemibhobho, ibonelela ngendlela elula nesebenzayo yokulawula ukuhamba kolwelo kunye neegesi.Phakathi kweentlobo ezahlukeneyo zeevalve zebhola ezikhoyo, iivalve zebhola ezimbini zikhethiweyo ezithandwayo ngenxa yokuguquguquka kwazo kunye nokuthembeka.Kweli nqaku, siza kuhlolisisa ukusetyenziswa kweevalve zebhola, xa usebenzisa i-valve yebhola ephindwe kabini, kunye neenzuzo zokukhetha ukhetho oluphezulu oluvela kumthengisi ohloniphekileyo wevalve yebhola.
Yintoni injongo yevalve yebhola?
Injongo ephambili yeevalvu zebhola kukulawula ukuhamba kwamanzi kwimibhobho.Iqukethe idiski engqukuva (okanye ibhola) enemingxuma embindini, enokuthi ijikwe ukuze ivumele okanye ithintele ukuhamba kwemidiya.Xa iivalve yebholaikwindawo evulekileyo, umngxuma uhambelana nombhobho, ukuvumela ukuba imidiya idlule.Xa ikwindawo evaliweyo, umgodi u-perpendicular kumbhobho, ukuthintela ukuhamba.
Iivalvu zebhola ziqhele ukusetyenziswa kumashishini ahlukeneyo, kubandakanywa ioli kunye negesi, i-petrochemicals, amanzi kunye nonyango lwamanzi amdaka, ukuveliswa kwamandla, kunye nokunye.Zithandwa ngenxa yokukwazi ukuvala ngokukhawuleza nangokuthembekileyo, kunye nokukwazi ukumelana noxinzelelo oluphezulu kunye namaqondo obushushu.
Ndingayisebenzisa nini ivalve yebhola enamacandelo amabini?
A iveluve yebhola enamacandelo amabiniluhlobo olukhethekileyo lwevalvu yebhola enamalungu amabini ahlukeneyo, umzimba kunye nesiphelo se-cap.Olu luyilo kulula ukuyigcina kunye nokulungiswa ukususela ekubeni i-valve inokutshatyalaliswa ngaphandle kokuyisusa kumbhobho.Ilungele izicelo ezifuna ukulungiswa rhoqo okanye ukuhlolwa, kunye neenkqubo ezinokufuna ukuguqulwa okanye ukuphuculwa kwixesha elizayo.
Ivalve yebhola esisigxina enamacandelo amabini eveliswe yi-CEPAI isetyenziselwa ukusika okanye ukudibanisa okuphakathi kumbhobho.Ingasetyenziswa emanzini, umphunga, i-oyile, i-liquefied gas, igesi yendalo, igesi yamalahle, i-nitric acid, i-urea kunye nezinye imidiya.Oku kwenza kube lukhetho oluguquguqukayo kwiintlobo ezahlukeneyo zezicelo zoshishino ezinokufuna ulawulo lweentlobo ezahlukeneyo zeendaba.Ukongezelela, idizayini ye-trunnion iqinisekisa ukuzinza okukhulu kunye nenkxaso yebhola, ivumela uxinzelelo oluphezulu kunye nobukhulu obukhulu.
Ukukhetha umboneleli wevalve yebhola echanekileyo kubalulekile ekuqinisekiseni umgangatho wevalvu kunye nokusebenza.Ababoneleli abahloniphekileyo abafana ne-CEPAI banikezela ngoluhlu olubanzi lweenketho ukuze zihambelane neemfuno ezahlukeneyo kwaye iimveliso zabo zenziwe ngemigangatho yamazwe ngamazwe ukuqinisekisa ukuthembeka kunye nokuqina.
Ukuqukumbela, iivalve zebhola zidlala indima ebalulekileyo ekulawuleni ukuhamba kwamanzi kwimibhobho, kwaye iivalve zebhola ezinamaqhekeza amabini ziyindlela eguquguqukayo nesebenzayo kwizicelo ezininzi.Lukhetho oludumileyo kuwo wonke amashishini ngenxa yokulula ukugcinwa kunye nokulungiswa kunye nokukwazi ukuphatha uluhlu olubanzi lwee-voltages eziphakathi kunye eziphezulu.Xa ukhetha i-valve yebhola ezimbini, kubalulekile ukuqwalasela iimfuno ezithile zenkqubo kwaye ukhethe umthengisi othembekileyo ukuqinisekisa umgangatho kunye nokusebenza kwevalve.
