I-valve yebhola licandelo eliphambili kulo naliphi na inkqubo yokubhobhoza, ibonelela ngendlela elula nesebenzayo yokulawula ukuhamba kolwelo kunye neegesi. Phakathi kweentlobo ezahlukeneyo zeevali zebhola ezikhoyo, i-valves yebhola ezimbini zilukhetho oludumileyo ngenxa yokungahambi kakuhle nokunyaniseka. Kweli nqaku, siza kuphonononga ukusetyenziswa kweeValves zeBhola, xa zisebenzisa ivalve yebhola ezimbini, kwaye izibonelelo zokukhetha ukhetho oluphezulu kumthengisi we-valve odumileyo.
Yintoni injongo ye-valve yebhola?
Eyona njongo iphambili yeevalves zebhola kukulawula ukuhamba kweembiza kwimibhobho. Ine-disk yediski ye-slering (okanye ibhola) ngomngxunya kwiziko, elinokuguqulwa ukuze livumele okanye lithintele ukuhamba kwemidiya. Xaivalve yebholaikwindawo evulekileyo, umngxunya uhambelana nombhobho, uvumele amajelo eendaba ukuba adlule. Xa ikwindawo evaliweyo, umngxunya ugqitha kumbhobho, umngxunya wokuvala.
Iivalves zebhola zisetyenziswa rhoqo kwimizi-mveliso eyahlukeneyo, kubandakanya ioyile kunye negesi, i-petrochemicals, amanzi kunye nokuveliswa kwamanzi amdaka, nangaphezulu. Bazithanda ukukwazi kwabo ukuvala ngokukhawuleza kwaye ngokuthembekileyo, kunye namandla abo okumelana noxinzelelo olukhulu kunye namaqondo obushushu.
Ndingayisebenzisa nini ivalve yebhola ezimbini?
A I-valve yebhola ezimbiniLuhlobo olukhethekileyo lwevalve yebhola enamacandelo amabini awahlukeneyo, umzimba kunye nesiphelo sentloko. Olu kyilo lulula ukugcina nokulungisa ukusukela kwivalve kunokubakho ngaphandle kokususa ukusuka kumbhobho. Eyona nto ifanelekileyo kwizicelo ezifuna ukugcinwa okanye ukuhlolwa, kunye neenkqubo ezinokuthi zifuneke zilungiswe okanye ziphuculwe kwixesha elizayo.
I-pieti yesibini ye-velit ivelise i-valve yebhola eveliswe yi-CAEPAI ikakhulu isetyenziselwa ukusika okanye iqhagamshela iphakathi kumbhobho. Ingasetyenziswa emanzini, i-Steam, ioyile, irhasi ye-Liqueff, irhasi yendalo, igesi yelahleko, i-nitric acid, i-Urea kunye nezinye izinto zosasazo. Oku kubangela ukuba kuthathe ukhetho lweenkqubo zokusebenza zemveliso ezinokufuna ulawulo lweentlobo ezahlukeneyo zemithombo yeendaba. Ukongeza, uyilo lwe-Trinnion luqinisekisa uzinzo olukhulu kunye nenkxaso yebhola, ukuvumela uxinzelelo oluphezulu kunye nobukhulu obukhulu.
Ukukhetha umthengisi we-valve efanelekileyo kubalulekile ekuqinisekiseni umgangatho we-veli kunye nokusebenza. Abathengisi abadumileyo abathanda uluhlu olubanzi lweendlela zokhetho ukuze zilungele iimfuno ezahlukeneyo kunye neemveliso zabo zenziwa kwimigangatho yehlabathi ukuqinisekisa ukuthembeka kunye nokuqina.
Ukuqukumbela, ivisi lebhola lidlala indima ebalulekileyo ekulawuleni ukuhamba kweembiza kwimibhobho, kwaye i-valves yebhola ezimbini ziindlela eziguquguqukayo nezicelo ezininzi. Luhlobo oluthandwayo kumashishini amashishini ngenxa yokulungiswa kwayo kwisondlo kwaye kulungiswa kunye nokukwazi ukuphatha uluhlu olubanzi lwamabala aphakathi kunye aphezulu. Xa ukhetha ivalve yebhola ezimbini, kubalulekile ukuqwalasela iimfuno ezithile zenkqubo kwaye ukhethe umthengisi othembekileyo ukuqinisekisa umgangatho kunye nokusebenza kwevalve.
