Xa ufaka iivalve, gcina ezi ngongoma engqondweni xa usebenzisa iivalve ezine-fluorine

Xa ufaka i-valve, gcina ezi ngongoma engqondweni xa usebenzisa i-fluorine i-valve ene-fluorine i-valve ene-directional, njenge-valve ye-globe, i-valve ye-throttle, i-valve yokunciphisa uxinzelelo, i-valve yokukhangela, njl., Ukuba ifakwe ngasemva, iya kuchaphazela ukusetyenziswa kwempembelelo. kunye nobomi (ezifana nevalve ye-throttle), okanye zingasebenzi kwaphela (ezifana nevalve yokunciphisa uxinzelelo), kwaye zibangele ingozi (njengevalve yokukhangela). Ivalve ngokubanzi, kukho uphawu lolwalathiso kumzimba wevalvu; Ukuba akunjalo, kufuneka ichongwe ngokuchanekileyo ngokomgaqo wokusebenza kwevalvu. Igumbi levalve elijikeleze ivalve yeglowubhu liyi-asymmetrical, ulwelo lokuyivumela ukusuka ezantsi ukuya phezulu ngezibuko levalve, ngoko ke ukuxhathisa ulwelo kuncinci (kumiselwa yimilo), ukusindisa umsebenzi ovulekileyo (ngenxa yoxinzelelo oluphakathi phezulu) , ivaliwe emva kokupakishwa koxinzelelo oluphakathi, kulula ukuyilungisa, yingakho i-valve yeglobhu ayikwazi ukufaka inyaniso. Ezinye iivalve zineempawu zazo. I-Valve INSTALLATION POSITION, kufuneka kube lula ukusebenza: KWABA ukufakwa kunzima okwethutyana, kodwa kunye nomsebenzi wexesha elide lomsebenzi. I-valve handwheel kunye nokulungelelaniswa kwesifuba (ngokubanzi i-1.2 yeemitha ukusuka kumgangatho wokusebenza), ukwenzela ukuba ukuvulwa nokuvalwa kwevalve kukuncinci. Ivili lesandla sevalve yomgangatho kufuneka lijonge phezulu kwaye lingathambeki ukunqanda ukusebenza kakubi. Ivalve yomatshini wodonga ixhomekeke kwisixhobo, kwaye umqhubi kufuneka naye ashiywe kwindawo yokuma. Ukuze ugweme ukusebenza kwesibhakabhaka, ngakumbi i-asidi kunye ne-alkali, imidiya enetyhefu, ngaphandle koko ayikhuselekile. Isango akufanele liguqulwe (oko kukuthi, i-handwheel iphantsi), ngaphandle koko i-medium iya kugcinwa kwindawo yokugubungela ixesha elide, i-corrode i-stem ngokulula, kunye ne-taboo yenkqubo ethile. Kunzima kakhulu ukutshintsha ukupakisha ngaxeshanye. Vula iivalvu zesango le-STEM, MUSA UKUFAKA ngaphantsi komhlaba, kungenjalo ngenxa yokuhlwa okumanzi kwesiqu esiveziweyo. Phakamisa ivalve yokukhangela, ufakelo lokuqinisekisa ukuba idiskhi yevalve ngokuthe nkqo, ukuze ukuphakamisa kube bhetyebhetye. Ivalve yokukhangela i-Swing, xa ifakwe ukuqinisekisa ukuba inqanaba le-pin, ukuze ujingi ube bhetyebhetye. Ivalve yokunciphisa uxinzelelo iya kufakwa ngokuthe tye kumbhobho othe tye, kwaye ayiyi kuthambekela nakweliphi na icala. Ukufakela kunye nokwakhiwa kufuneka kulumke, musa ukubetha i-valve eyenziwe ngezinto ezinqabileyo. Ngaphambi kokufaka, i-valve kufuneka ihlolwe ukujonga iinkcukacha kunye neemodeli ukuchonga nawuphi na umonakalo, ngakumbi kwisiqu. Kwakhona ujike amaxesha ambalwa ukuze ubone ukuba i-skewed, kuba kwinkqubo yokuthutha, kulula ukubetha i-stem skewed. Kwakhona *** inkunkuma kwivalve. XA UPHAKAMISA IMVAVANE, INTAMBO AKUFUNEKA IBOTSHWE KWISANDLA OKANYE ISIQINISEKISO UKUTHINTA UKONAKALA KWEZI NDAWO. KUFUNEKA KUBOTSHWE KWIFANGE. Umgca apho i-valve idityaniswe khona kufuneka icocwe. Umoya ocinezelweyo unokusetyenziselwa ukuvuthela iifayili ze-iron oxide, isanti, i-welding slag kunye nezinye ii-sundries. Le nkunkuma, akukho lula nje ukukrazula indawo yokutywina yevalve, amaqhekeza amakhulu enkunkuma (njenge-slag ye-welding), kodwa inokuthintela i-valve encinci, ukwenzela ukuba ukusilela kwayo. Xa UFAKA I-SKREW valve, UKUPAKA UKUTYA (I-WIRE NE-aluminium yeoli OKANYE i-PTFE RAW belt material) kufuneka ifakwe kwintambo yombhobho, ungangeni kwi-valve, ukwenzela ukuba ugweme umthamo wememori yevalve, uchaphazele ukuhamba okuphakathi. Xa ufaka i-valve ye-flange, nikela ingqalelo ekuqiniseni iibholithi ngokulinganayo kwaye ngokulinganayo. I-valve flange kunye ne-flange yombhobho kufuneka ihambelane, ukucocwa kunengqiqo, hleze i-valve ivelise uxinzelelo olugqithisileyo, kunye nokuqhekeka. Kwizinto ezinqabileyo kwaye kungekhona amandla aphezulu e-valve, ingqalelo ekhethekileyo kufuneka ihlawulwe. Ivalve ekufuneka idityaniswe ngombhobho iya kuba yindawo edityanisiweyo kuqala, emva koko indawo evaliweyo iya kuvuleka ngokupheleleyo, ize idityaniswe ifile. Ezinye iivalvu kufuneka zibe nokhuseleko lwangaphandle, oko kukugcina ubushushu kunye nokugcinwa kwengqele. I-insulation layer ngamanye amaxesha ixutywa nemigca yomphunga oshushu. Luluphi uhlobo lwevalve olufanele lube lubushushu okanye lubandayo, ngokweemfuno zemveliso. Ngokomgaqo, apho i-valve medium ukunciphisa iqondo lobushushu kakhulu, kuya kuchaphazela ukusebenza kakuhle imveliso okanye ivalve emkhenkceni, kufuneka uhlale ushushu, nkqu ubushushu mix; Apho ivalve ingenanto, engalunganga kwimveliso okanye ibangele iqabaka kunye nezinye izinto ezimbi, kufuneka uhlale ubanda. Izinto zokugquma i-asbestos, uboya be-slag, uboya beglasi, i-perlite, i-diatomite, i-vermiculite, njl.; Izinto zokupholisa ziyi-cork, i-perlite, i-foam, iplastiki kunye nokunye. Ezinye iivalve, ngaphezu kwezibonelelo eziyimfuneko zokukhusela, nazo zine-bypass kunye ne-instrumentation. Kufakwe i-bypass. Kulula ukulungisa umgibe. Ezinye iivalve, nazo zifakwe i-bypass. Ukufakwa kwe-bypass kuxhomekeke kwimeko yevalvu, ukubaluleka, kunye neemfuno zemveliso. I-valve yesitoko, ukupakisha okuthile akuzange kube kuhle, kwaye ezinye azihambelani nokusetyenziswa kweendaba, ezifuna ukubuyisela ukupakisha. Umzi-mveliso weValve awukwazi ukuqwalasela ukusetyenziswa kwamawaka eentlobo ezahlukeneyo zeendaba, ibhokisi yokupakisha isoloko igcwele ingcambu eqhelekileyo, kodwa xa isetyenziswa, kufuneka ivumele ukupakisha phakathi ukulungelelanisa. Xa utshintsha ukupakisha, cinezela ngqukuva. Umthungo ngamnye wendandatho ukuya kuma-degrees angama-45 ufanelekile, ring kunye ne-ring uvule i-180 degrees. Ukuphakama kokupakisha kufuneka kuthathelwe ingqalelo i-leeway ukuze i-gland iqhubeke nokucinezela, kwaye ngoku kuyafuneka ukuba indawo esezantsi ye-gland icinezele igumbi lokupakisha kubunzulu obufanelekileyo, obunokuthi ngokubanzi bube yi-10-20% yobunzulu bubonke bobunzulu. igumbi lokupakisha. Kwiivalve ezifunayo, i-joint Angle yi-30 degrees. Umthungo ophakathi kweringi kunye neringi ugxadazele ngamadigri angama-120. Ukongeza ukupakisha, kodwa ngokwemeko ethile, ukusetyenziswa kwerabha O-ring (irabha yendalo ukumelana 60 degrees Celsius buthathaka alkali, butadiene irabha ukumelana ukuya 80 degrees Celsius ikristale oyile, Fluorine irabha ukumelana ezahlukeneyo ezonakalisayo. media ngezantsi 150 degrees celcius) ezintathu zipakishwe polytetrafluoron ring (ixhathise eendaba eyomeleleyo edlekayo ngaphantsi kwama-200 degrees Celsius) nenayiloni isitya umsesane (resistant ukuya 120 degrees Celsius ammonia, alkali) kunye nezinye ezenza filler. Umaleko we-TEflon we-tape yezinto eziluhlaza unokuphucula umphumo wokutywina kunye nokunciphisa ukubola kwe-electrochemical ye-valve stem. Xa ucinezela i-seasoning, jika i-stem ngaxeshanye ukugcina yonke indawo ngokulinganayo, kwaye uthintele ukufa kakhulu, qinisa i-gland ukuze unyanzelise ngokulinganayo, awukwazi ukuthambeka. Iivalve zeFluorine-butterfly zisebenzisa imiba efuna ukuhoywa. Iivalve zeFluorine-butterfly zeflange azikwazi kuvuleka ngaphandle kokuba zilungisiwe kunye noqhagamshelo lombhobho, kungenjalo umphezulu we-PTFE flange unokubangelwa ngumahluko wobushushu, imizimba yangaphandle, ukunkqonkqoza ngokuchasene nemikrwelo okanye ukugqwethwa nokutywinwa, okufana nokushukuma. ibhodi yokusibekela imfuno yokuhlolwa, kwakhona kufuneka ihlale isantya iya kugubungela ipleyiti ukuseta kwakhona emva kokuhlolwa, ukwenzela ukukhusela umphezulu PTFE flange. Ufakelo lwevalve yolwelo lwefluorine, ukusetyenziswa kwevalve yefluorine yevalve ye-fluorine efakwe ipleyiti yesigqubuthelo seflange ayinakuvulwa ngokuthanda, ngaphandle kokuba ikulungele ukudibanisa nombhobho, kungenjalo umphezulu we-PTFE flange unokuba ngenxa yomahluko wobushushu, umzimba wangaphandle obangelwa kukukrweleka okanye ukugqwetheka nokuchaphazela ukutywinwa, okufana nemfuneko yokuhambisa ipleyiti yesigqubuthelo, nayo kufuneka ihlolwe emva kwesantya sokuseta kwakhona ipleyiti yesigqubuthelo, ukukhusela umphezulu we-PTFE flange. Ivalve enemigca emi-2 kunye noqhagamshelo lombhobho, ngokubanzi kwaye ayisasebenzi yodwa i-gasket, kodwa inezinto ezifanayo (umphezulu wesinyithi, njl.njl.) umphezulu weflange, kufuneka isebenzise i-gasket efanelekileyo, ukuze kukhuselwe umphezulu we-PTFE flange. Ekusetyenzisweni kweNKQUBO, UKUBA UKUVUZA KWENZEKA KWIqondo lokushisa ELIPHEZULU, Ukushisa kwenkqubo kufuneka kuncitshiswe kwiqondo lokushisa lokuqala, emva koko ufumane isizathu sokugcinwa. Ngexesha lofakelo, amandongomane eflange kufuneka aqiniswe ngokulinganayo kwicala lediagonal (symmetric) kwaye axhotyiswe ngetorque efanelekileyo: a Ukuba indawo yokutywina yeflange iyavuza kwaye i-nati kwindawo yokuvuza itshixiwe, i-nati kwindawo yokuvuza kufuneka ikhululwe kangangesiqingatha. ukujika kunye necala elichasene ne-nut kufuneka liqiniswe kwakhona nge-torque efanayo; B Ukuba le ndlela ingentla ayikayeki ukuvuza, kufuneka ukhangele umphezulu we-PTFE we-flange ukuba kukho i-concave kunye ne-convex indentation, i-scratch, ngoko ke ifumaneka iphepha lomsonto, ilaphu eliza kuhanjiswa kwaye lidityaniswe kwakhona. UNGAWENZA NAMUPHI NA UMSEBENZI WOKUSHISA OKUPHEZULU KWI-FLUORINE LINEED VALVES UKUZE ugweme UKONAKALA IXESHA ELIDE KULENKO. 6 Iivalve ezine-fluorine ezinemigca kufuneka zigcinwe kwigumbi elomileyo nelingena umoya. Musa ukuzipakisha. I-FLUORINE LINED VALVE EMVA KOKULUNGISWA KUYA KUVAVANYWA kwaye ifaneleke ngokwemigangatho efanelekileyo phambi kokuba ifakwe. Xa USEBENZA NGEMANDLA I-valve ye-FLUORINE LINED, AKUVUMELEKANGA UKUNYANZELELA UKUVULA NOKUVALA I-valve NGONCEDO LWEZINYE izitshixo. Iimfuno ezi-9 zolwalathiso lwevalve ene-fluorine ekufakeni okuphakathi kufuneka zithathele ingqalelo isalathiso sotolo kumzimba wevalvu, kwaye uqinisekise ukuba ukusebenza kunye nokugcinwa kulungele. I-10 yokugcina ixesha elide le-fluorine efakwe kwivalve yokutywina iperi kufuneka ivuleke kancinane kwaye yahlulwe, ukuphepha ukuguqulwa kwexesha elide lomphezulu wokutywina phantsi koxinzelelo lwexesha elide, okuchaphazela ukusebenza kokutywinwa kunye nobomi benkonzo.
