Lapho ufaka ama-valve, gcina la maphuzu engqondweni lapho usebenzisa ama-valve ane-fluorine anemigqa Ama-valve amaningi ane-directional, njenge-globe valve, i-throttle valve, i-valve yokunciphisa ukucindezela, i-valve yokuhlola, njll, uma ifakwe ngokuhlehlayo, izothinta ukusetshenziswa komphumela. nempilo (njenge-throttle valve), noma ingasebenzi nhlobo (njenge-valve yokunciphisa ukucindezela), futhi ibangele ingozi (njenge-valve yokuhlola). I-valve evamile, kunophawu lokuqondisa emzimbeni we-valve; Uma kungenjalo, kufanele ikhonjwe ngendlela efanele ngokuvumelana nesimiso sokusebenza kwe-valve. Igumbi le-valve elizungeze i-valve yembulunga alilingani, liwuketshezi lokulivumela lisuka phansi liye phezulu ngembobo ye-valve, ngakho ukumelana noketshezi kuncane (kunqunywa ukuma), ukonga umsebenzi ovulekile (ngenxa yokucindezela okuphakathi phezulu) , ivaliwe ngemva kokupakishwa kwengcindezi ephakathi, kulula ukuyilungisa, yingakho i-valve yomhlaba ingakwazi ukufaka iqiniso. Amanye ama-valve anezici zawo siqu. I-valve INSTALLATION POSITION, kufanele ibe lula ukuyisebenzisa: NOMA ngabe ukufaka kunzima okwesikhashana, kodwa nomsebenzi wesikhathi eside womsebenzisi. Isondo lesandla se-valve nokuqondisa kwesifuba (ngokuvamile amamitha angu-1.2 ukusuka endaweni yokusebenza), ukuze ukuvulwa nokuvala kwe-valve kube umzamo omncane. Isondo lesandla sevalvu yaphansi kufanele libheke phezulu futhi lingatsheki ukuze kugwenywe ukusebenza kabi. I-valve yomshini wodonga incike emishinini, futhi opharetha kufanele ashiywe endaweni emile. Ukuze ugweme ukusebenza kwesibhakabhaka, ikakhulukazi i-asidi ne-alkali, imidiya enobuthi, ngaphandle kwalokho ayiphephile. Isango akufanele liguqulwe (okungukuthi, isondo lesandla liphansi), ngaphandle kwalokho okuphakathi kuzogcinwa esikhaleni sekhava isikhathi eside, kulula ukugqwala isiqu, futhi kwezinye izidingo zenqubo taboo. Kunzima kakhulu ukufaka esikhundleni sokupakisha ngesikhathi esifanayo. Vula AMAVAVAVA WE-STEM GATE, UNGAFAKI ngaphansi komhlaba, ngaphandle kwalokho ngenxa yokugqwala okumanzi kwesiqu esivelile. Phakamisa i-valve yokuhlola, ukufakwa ukuze uqinisekise ukuthi i-valve disc ime mpo, ukuze i-lift iguquguquke. Swayipha i-valve yokuhlola, lapho ifakiwe ukuze kuqinisekiswe ukuthi izinga lephinikhodi, ukuze linyakaze liguquguquke. I-valve yokunciphisa umfutho izofakwa iqonde epayipini elivundlile, futhi akufanele itshekele kunoma iyiphi indlela. Ukufakwa nokwakhiwa kufanele kuqaphele, ungashayi i-valve eyenziwe ngezinto eziphukayo. Ngaphambi KOKUFAKA, IVAVU KUFANELE IYAHLOLWA UKUZE kubhekwe imininingwane KANYE namamodeli ukuze kubonakale noma yimuphi umonakalo, ikakhulukazi wesiqu. Futhi vula izikhathi ezimbalwa ukuze ubone ukuthi i-skewed, ngoba ngesikhathi sokuthutha, kulula ukushaya i-stem skewed. Futhi *** udoti ku-valve. UMA UPHAKAMISA IVAVAVU, INTAMBO AKUMELE IBOSHWE ESANDWENI NOMA ISIQINISEKISO UKUZE UGWEME UKULIMALA KWALEZI ZINgxenyana. KUFANELE KUBOSHWE EMHLABENI. Umugqa lapho i-valve ixhunywe khona kufanele ihlanzwe. Umoya ocindezelwe ungasetshenziselwa ukushaya amafayili e-iron oxide, isihlabathi, i-welding slag nezinye izinhlobo. Lezi mfucumfucu, akulula nje ukunwaya indawo yokuvala ye-valve, izinhlayiya ezinkulu zemfucumfucu (njenge-welding slag), kodwa futhi zingavimba i-valve encane, ukuze ukwehluleka kwayo. Lapho UFAKA I-VALVE YESIKREWU, UKUPHAKISWA KOKUVALWA (INTAMBO KAmafutha e-aluminium NOMA Ibhande lezinto ezibonakalayo le-PTFE RAW) kufanele liboshwe kuntambo yepayipi, ungangeni ku-valve, ukuze ugweme ivolumu yememori ye-valve, ithinte ukugeleza okuphakathi. Lapho ufaka ama-valve e-flange, qaphela ukuqinisa ama-bolts ngokulinganayo nangokulinganayo. I-valve flange kanye ne-pipe flange kufanele ihambisane, imvume inengqondo, funa i-valve ikhiqize ukucindezela okukhulu, ngisho nokuqhekeka. Ngezinto eziqinile futhi hhayi amandla aphezulu we-valve, ukunakwa okukhethekile kufanele kukhokhwe. I-valve ezoshiselwa ngepayipi kufanele ifakwe endaweni eshiselwe kuqala, khona-ke ingxenye evaliwe izovulwa ngokugcwele, bese i-welded ifile. Amanye ama-valve kufanele futhi abe nesivikelo sangaphandle, okuwukugcina ukushisa nokugcina amakhaza. I-insulation layer kwesinye isikhathi ixutshwa nemigqa yesitimu esishisayo. Hlobo luni lwe-valve okufanele lube ukushisa noma ukubanda, ngokuya ngezidingo zokukhiqiza. Empeleni, lapho medium valve ukunciphisa izinga lokushisa kakhulu, kuzothinta ukusebenza kahle ukukhiqizwa noma valve eqandisiwe, udinga ukufudumala, ngisho mix ukushisa; Lapho i-valve ingenalutho, ingalungile ekukhiqizeni noma ibangele isithwathwa nezinye izinto ezimbi, udinga ukubanda. Izinto zokufakelwa i-asbestos, uboya be-slag, uboya bengilazi, i-perlite, i-diatomite, i-vermiculite, njll; Izinto zokupholisa zingukhokho, i-perlite, igwebu, ipulasitiki nokunye. Amanye ama-valve, ngaphezu kwezinsiza ezidingekayo zokuvikela, nawo ane-bypass kanye nezinsimbi. I-bypass ifakiwe. Kulula ukulungisa isicupho. Amanye ama-valve, nawo afakwe i-bypass. Ukufakwa kwe-bypass kuncike esimweni se-valve, ukubaluleka, kanye nezidingo zokukhiqiza. I-valve yesitoko, ukupakisha okuthile akubanga kuhle, kanti okunye akuhambisani nokusetshenziswa kwemidiya, okudingeka kuthathelwe indawo yokupakisha. I-Valve factory ayikwazi ukucabangela ukusetshenziswa kwezinkulungwane zezinhlobo ezahlukene zemidiya, ibhokisi lokupakisha lihlala ligcwele impande evamile, kodwa lapho lisetshenziswa, kufanele livumele ukupakisha phakathi ukuze livumelane. Uma ushintsha ukupakisha, cindezela uzungeleze ngomjikelezo. Umthungo ngamunye wendandatho ukuya kuma-degree angama-45 kufanelekile, indandatho futhi ikhale ivuleke ngama-degree angama-180. Ukuphakama kokupakisha kufanele kucabangele i-leeway ukuze indlala iqhubeke nokucindezela, futhi manje kuyadingeka ukuvumela ingxenye engezansi ye-gland icindezele ikamelo lokupakisha ekujuleni okufanele, okungase kube ngu-10-20% wokujula okuphelele igumbi lokupakisha. Kuma-valve afunayo, i-engeli ehlangene ingama-degree angama-30. Umthungo ophakathi kwendandatho nendandatho inyakaza ngamadigri ayi-120. Ngaphezu kokupakisha, kodwa futhi ngokusho kwesimo esithile, ukusetshenziswa kwe-rubber O-ring (irabha yemvelo imelana no-60 degrees Celsius i-alkali ebuthakathaka, i-butadiene injoloba imelana no-80 degrees Celsius ikristalu kawoyela, i-Fluorine iraba imelana nezinhlobonhlobo zokubola. imidiya engaphansi kuka-150 degrees Celsius) indandatho emithathu eyisitaki ye-polytetrafluoron (imelana nemidiya egqwalayo eqinile engaphansi kuka-200 degrees Celsius) indandatho yesitsha senayiloni (imelana no-120 degrees Celsius ammonia, alkali) nokunye ukugcwaliswa okwenza. Ungqimba lwetheyiphu ye-TEflon eluhlaza lungathuthukisa umphumela wokuvala futhi lunciphise ukugqwala kwe-electrochemical kwesiqu se-valve. Lapho ucindezela isithokelo, vula isiqu ngesikhathi esifanayo ukugcina nxazonke ngokulinganayo, futhi uvimbele ukufa kakhulu, qinisa indlala ukuphoqa ngokulinganayo, awukwazi ukutsheka. Amavalvu e-fluorine-butterfly asebenzisa izinto ezidinga ukunakwa Ama-valve e-Fluorine-butterfly ama-flange cover plate awakwazi ukuvuleka ngaphandle uma kulungisiwe nokuxhunywa kwepayipi, ngaphandle kwalokho i-PTFE flange surface ingase ibangwe umehluko wokushisa, imizimba yangaphandle, ukungqubuzana nokuklwebheka noma ukuhlanekezela nokuvala, njengokunyakaza. ikhava ibhodi ngesidingo sokuhlola, futhi kufanele uhlale isivinini sizovala ipuleti ukusetha kabusha ngemva kokuhlolwa, ukuze kuvikelwe PTFE flange surface. Ukufakwa kwevalvu yolwelwesi lwe-fluorine, i-fluorine lining valve isebenzisa ipuleti eli-1 le-fluorine eline-fluorine eline-flange alikwazi ukuvulwa ngokuthanda, ngaphandle uma selilungele ukuxhuma nepayipi, ngaphandle kwalokho indawo ye-PTFE flange ingase ibe ngenxa yomehluko wokushisa, umzimba wangaphandle obangelwa ukuklwebheka noma ukuhlanekezela futhi kuthinte ukubekwa uphawu, njengesidingo sokuhambisa ipuleti lekhava, nakho kufanele kuhlolwe ngemuva kwejubane lokusetha kabusha ipuleti lekhava, ukuvikela indawo ye-PTFE flange. 2 ivalvu efakwe umugqa we-fluorine kanye noxhumo lwamapayipi, ngokuvamile futhi angasasebenzisi iyodwa i-gasket, kodwa enempahla engafani (indawo yensimbi, njll.) ebheke phezulu, kufanele isebenzise i-gasket efanelekile, ukuze kuvikelwe ingaphezulu le-PTFE flange. EKUSETSHENZISWA KOHLELO, UMA UKUVUZA KWENZEKA EZWENI ELIPHEZULU, izinga lokushisa lohlelo kufanele lehliswe libe izinga lokushisa legumbi kuqala, bese uthola isizathu sokulungiswa. Ngesikhathi sokufakwa, amantongomane e-flange kufanele aqiniswe ngendlela efanayo ohlangothini lwe-diagonal (i-symmetric) futhi afakwe i-torque efanele: a ukuphenduka kanye nohlangothi oluphambene lwenati kufanele luqiniswe futhi nge-torque efanayo; B Uma le ndlela engenhla ingakayeki ukuvuza, kufanele ihlole indawo ye-PTFE flange ukuthi kukhona ukuhlehla kwe-concave ne-convex, ukuklwebha, bese kutholakala intambo yephepha, indwangu okufanele ilinganiswe futhi ixhunywe kabusha. UNGAWENZI YILUPHI UMSEBENZI WOKUSHISA OKUPHEZU KOKUSHISA EMAVAVAVU ANE-FLUORINE Ukugwema UKULIMALA ESIDE ESIKHATHINI LESIBINI. 6 Amavalvu ane-fluorine anemigqa kufanele agcinwe ekamelweni elomile nelingena umoya. Ungawapakishi. I-FLUORINE LINED VALVE NGEMVA KOKUKHANDISWA IYOHLOLWA futhi ifaneleke ngokuvumelana nezindinganiso ezifanele ngaphambi kokufakwa. Lapho USEBENZA NGEMANDLA IVAVAVU ELANDELWE I-FLUORINE, AKUVUMELEKILE UKUVULA FUTHI UVALE IVAVVU NGOSIZO LWEZINYE izinsimbi. Izidingo eziyisi-9 zokuqondisa ze-fluorine valve efakwe umugqa ekufakweni kwendawo kufanele inake isiqondiso somcibisholo osemzimbeni we-valve, futhi iqinisekise ukuthi ukusebenza nokugcinwa kulula. 10 isitoreji sesikhathi eside sepheya yokuvala ivalve ene-fluorine enomugqa kufanele ivuleke kancane futhi ihlukaniswe, ukugwema ukuguquguquka kwesikhathi eside kwendawo yokuvala ngaphansi kwengcindezi yesikhathi eside, kuthinte ukusebenza kokuvala nempilo yesevisi.
