Njengesixhobo esibalulekileyo sokulawula ulwelo, ubungakanani bokukhetha uhlobo kunye nokukhethwa kwezinto zevalve yebhabhathane yomgca ophakathi kubaluleke kakhulu ekusebenzeni kwenkqubo kunye nobomi benkonzo. Eli nqaku liza kuxoxa nzulu ngokubaluleka kobungakanani kunye nokukhethwa kwezinto zevalve yebhabhathane yomgca ophakathi, kwaye inike iingcebiso kunye nezilumkiso kubafundi.
Icandelo lokuqala: Ivalve yebhabhathane yomgca ophakathi isetyenziswa kakhulu kumashishini ahlukeneyo eenkqubo zokulawula ulwelo, indima yalo kukulawula ngokukhawuleza nangokuthembekileyo ulwelo lweendaba kunye nokuvala kunye nommiselo. Ubungakanani obuchanekileyo kunye nokukhethwa kwezinto ezifanelekileyo zizinto eziphambili zokuqinisekisa ukusebenza okugqwesileyo kunye nokusebenza okuthembekileyo kwevalve yebhabhathane yomgca ophakathi.
Icandelo lesibini: Okokuqala, ukhetho lobungakanani bevalve yebhabhathane yomgca ophakathi yenye yezinto eziphambili ezichaphazela ukusebenza kwayo. Ubungakanani obufanelekileyo bunokuqinisekisa iimpawu zokuhamba, ukuchasana noxinzelelo kunye nokusebenza kokutywinwa kwevalve. Ngokuxhomekeke kubume bendawo yolwelo, iimfuno zokuqukuqela kunye neemeko zokusetyenziswa, kuyafuneka ukuba kukhethwe idiameter efanelekileyo yevalvu kunye nendawo yokuvula isihlalo. Ubungakanani obukhulu okanye obuncinci kakhulu bunokubangela ukulawulwa kolwelo olungachanekanga, ukusetyenziswa kwamandla ngokugqithisileyo, kunye nomonakalo wezixhobo.
Icandelo lesithathu: Okwesibini, ukhetho lwempahla yevalve yebhabhathane yomgca ophakathi ibalulekile ekuxhathiseni umhlwa, ukumelana nokunxiba kunye nobomi benkonzo. Imidiya eyahlukeneyo ineempawu ezahlukeneyo zeekhemikhali, ngoko ukukhetha izinto ezifanelekileyo kunokuthintela ngokufanelekileyo ukubola, ukugqoka kunye nokuguga kwezinto. Izinto ezisetyenziswa ngokuqhelekileyo ziquka i-carbon steel, insimbi engenasici, isinyithi esityhidiweyo kunye ne-alloys zethusi. Ngokutsho kwe-asidi kunye ne-alkali ye-medium, iqondo lokushisa kunye noxinzelelo kunye nezinye iimeko, ukukhetha izinto ezifanelekileyo kunokwandisa ubomi benkonzo ye-valve butterfly.
Icandelo lesi-4: Xa ukhetha ubungakanani kunye nempahla yevalve yebhabhathane yomgca ophakathi, ezi zinto zilandelayo zibalulekileyo kufuneka ziqwalaselwe. Eyokuqala ziimpawu zesixhobo solwelo, kubandakanywa ubushushu, uxinzelelo, i-viscosity, njl.njl. Eyesibini yimpembelelo yemithombo yeendaba ezilulwelo kwivalve, njengokugqwala, ukurhawuzelela kunye ne-thermal conductivity yomphunga. Ukongeza, kuyafuneka ukuba kuqwalaselwe iimeko zokusetyenziswa, njengendawo yokubeka, umahluko woxinzelelo olusebenzayo kunye nemowudi yokusebenza kwevalvu.
Ngokusekelwe kule miba ingentla, sinika ezi ngcebiso zilandelayo kwireferensi yabafundi: 1. Xa ukhetha ubungakanani bevalve yebhabhathane yomgca ophakathi, kuyimfuneko ukuqwalasela ngokupheleleyo ukuhamba, uxinzelelo kunye nesantya solwelo oluphakathi kwaye ukhethe ivalve efanelekileyo. ububanzi kunye nendawo yokuhlala. 2. Xa ukhetha izinto eziphathekayo ze-valve ye-butterfly yomgca ophakathi, kuyimfuneko ukukhetha izinto ezinokumelana nokubola kunye nokugqoka ngokwemichiza yeekhemikhali ze-medium kunye neemeko zokusetyenziswa. I-3, ekukhetheni, kuyafuneka ukuba udibane neenjineli eziqeqeshiweyo okanye abavelisi, ngokwemeko yokwenyani yovavanyo olubanzi kunye nokwenza izigqibo.
Njengenxalenye ebalulekileyo yenkqubo yokulawula ulwelo, ubungakanani kunye nokukhethwa kwezinto eziphathekayo zevalve yebhabhathane kubaluleke kakhulu. Ukhetho oluchanekileyo lunokuqinisekisa ukuba i-valve ye-butterfly yomgca ophakathi inomsebenzi ogqwesileyo, amandla okulawula okuzinzile kunye nobomi benkonzo ende emsebenzini. Ngoko ke, sifanele siqonde ngokupheleleyo ukubaluleka kobukhulu kunye nokukhethwa kwezinto eziphathekayo zomgca we-butterfly valve, kwaye sinikele ingqalelo eyaneleyo kunye nenkxalabo kwiprojekthi yangempela. Ngokusebenzisa ubungakanani obufanelekileyo kunye nokukhethwa kwezinto eziphathekayo, unokuphucula ukusebenza kakuhle, ukuthembeka kunye nokhuseleko lwenkqubo.
Ukongezelela, ngenkqubela phambili eqhubekayo yenzululwazi nobugcisa, ezinye izinto ezintsha ngokuthe ngcembe zisetyenziswa ekwenzeni izivalo zebhabhathane zomgca ophakathi.
