Izinyathelo zokuzivikela lapho ufaka ama-valve Ukusebenza okuvamile kwama-valve e-fluorine ane-anticorrosive lined

 
Lapho i-valve ifakiwe, umsebenzisi akufanele aqonde indlela yayo yokufaka kuphela, ngoba i-valve ifakwe lapho ukuvikelwa nakho kubaluleke kakhulu. Uma unganaki ngesikhathi sokufakwa, kulula ukubangela umonakalo noma ukuvuza kwe-valve, okuzodala izinkinga eziningi. Ngakho-ke ungavikela kanjani lapho ufaka i-valve? I-Xiaobian elandelayo izokwethula ngokuqondile izinyathelo zokuvikela zokufakwa kwevalvu.
Hlola ukuvikelwa kwe-valve
UKUZE KUVIKELE UKUVUZA kwevalve yokuhlola noma ukugeleza kwezindaba ngemuva kokwehluleka, okuholela ekwehleni kwekhwalithi yomkhiqizo, izingozi neminye imiphumela emibi, ivalve yokusika eyodwa noma amabili abekwe ngaphambi nangemuva kwevalvu yokuhlola. Uma ama-valve amabili okuvala enikezwa, i-valve yokuhlola ingasuswa kalula ukuze isebenze.
Izinsiza zokuvikela amavalvu okuphepha
Indlela yokufaka ngaphambi nangemva kokujwayelekile ungabeki i-valve yokuhlukanisa, kuphela ezimweni zomuntu ngamunye, ingasetshenziswa. Uma amandla aphakathi nendawo equkethe izinhlayiya eziqinile, ezithinta i-valve yokuphepha ayikwazi ukuvalwa ngemva kokusuka, ukufaka i-valve yesango evalwe ngomthofu ngaphambi nangemva kwe-valve yokuphepha, i-valve yesango kufanele ibe sesimweni esivuleke ngokugcwele, i-valve yesango. kanye nevalvu yokuphepha efakwe ngqo i-valve yokuhlola i-DN20 emkhathini.
Lapho ukukhululeka kwe-wax nezinye imidiya kuzinga lokushisa elilingana negumbi lesimo esiqinile, noma ukunciphisa i-gasification yokucindezela futhi ukuze izinga lokushisa eliphakathi nendawo eliwuketshezi elikhanyayo libe ngaphansi kuka-0 degrees Celsius, ivalvu yokuphepha idinga ukushisa kwesitimu. Ivalvu yokuphepha yemidiya ebolayo, kuye ngokuthi i-valve imelana nokugqwala, cabanga ukwengeza ifilimu elimelana nokugqwala elingaqhume endaweni yokungena kwamavalvu. I-valve yokuphepha yegesi ngokuvamile ihlinzekwa nge-bypass valve ngokobukhulu bayo, njenge-vent manual.
Imishini yokuzivikela ye-valve yokunciphisa ingcindezi
Izikhungo zokufaka ama-valve okunciphisa ingcindezi ngokuvamile zinamafomu amathathu. Ama-gauge okucindezela afakwe ngaphambi nangemva kwe-valve yokunciphisa ukuze kube lula ukubhekwa kokucindezela ngaphambi nangemva kwe-valve. Kukhona i-valve yokuphepha evaliwe ngokugcwele ngemva kwe-valve ukuvimbela ukwehluleka kwe-valve yokunciphisa ingcindezi, i-valve ngemva kokucindezela kudlula ukucindezela okuvamile lapho gxuma, kuhlanganise ne-valve ngemva kwesistimu. Ipayipi lokukhipha amanzi lifakwe phambi kwe-valve ukusika i-valve, umsebenzi oyinhloko ukukhipha umfula ogelezayo, abanye basebenzisa isicupho. Umsebenzi oyinhloko wepayipi le-bypass yilapho ukwehluleka kwe-valve yokunciphisa ingcindezi, ukuvala i-valve yokunciphisa ingcindezi ngaphambi nangemva kwe-valve yokunqanyulwa, vula i-valve ye-bypass, ulungise ngesandla ukugeleza, udlale indima yesikhashana yokujikeleza, ukuze ulungise i-valve yokunciphisa ingcindezi noma shintsha i-valve yokunciphisa ingcindezi.
Imishini yokuvikela izicupho
Kunezinhlobo ezimbili zezicupho ezinepayipi le-bypass futhi alikho ipayipi le-bypass ohlangothini lwesicupho, ukubuyiswa kwe-condensate kanye nenkokhelo ye-condensate hhayi ukubuyisela, ukukhishwa kanye nezinye izidingo ezikhethekile zesicupho, zingafakwa ngokufana.
Isicupho esinevalve ye-bypass sisetshenziswa kakhulu ukukhipha inani elikhulu lamanzi ajiyile lapho ipayipi liqala ukusebenza. Uma USEVISA UDABA, AKUFANELEKILE UKUKHIPHA I-CONNDENSATE NGEPIYI LE-BYPASS, elingabangela isitimu ukuba siphumele OHLWENI LWAMANZI OKUBUYISEKA. Ngaphansi kwezimo ezijwayelekile, ungafaki ipayipi le-bypass. Kuphela lapho izinga lokushisa lokushisa lidingeka ngokuqinile, imishini eshisayo yokukhiqiza okuqhubekayo kufanele ifakwe ipayipi ye-bypass.
Ukusebenza okuvamile kwe-fluorine ene-anticorrosive valve enemigqa
I-fluorine ene-fluorine ene-plastic valve medium lokushisa: Izinhlobo ezahlukene zenkampani yethu yamavalve epulasitiki ane-fluorine, ukusetshenziswa kwepulasitiki ye-fluorine yi-F46 (FEP), ukusetshenziswa kwezinga lokushisa eliphakathi akukwazi ukudlula i-150 ℃ (izinga lokushisa eliphakathi lingaba ngu-150 ℃ isikhathi esifushane isikhathi eside, izinga lokushisa lokusetshenziswa kwesikhathi eside kufanele lilawulwe ku-120 ℃), ngaphandle kwalokho, izingxenye ze-valve ezifakwe ku-F46 kulula ukuthambisa, ukuguqulwa, okuholela ekuvaleni kwe-valve i-undead, ukuvuza okukhulu.
Uma izinga lokushisa elisetshenziswayo lingaphansi kuka-180 ℃ isikhathi esifushane, futhi izinga lokushisa lingaphansi kuka-150 ℃ isikhathi eside, kungase kukhethwe olunye uhlobo lwepulasitiki ye-fluorine; I-PFA, kodwa ehlanganiswe ne-PFA fluorine plastic ibiza kakhulu kune-F46 ngentengo.
2, ungabi nengcindezi engemihle. I-valve yepulasitiki enomugqa we-fluorine kufanele igweme ukusetshenziswa komfutho ongemuhle epayipini, uma kukhona ingcindezi engemihle, kulula ukubangela ukuthi ungqimba lwepulasitiki olufakwe ku-fluorine ludonswe ngaphandle (ukukhipha isigubhu), ukuxebuka, okuholela ekuvulekeni nasekuhlulekeni kokuvala. .
I-3, ingcindezi, umehluko wengcindezi kufanele ilawulwe ebangeni elivumelekile. Ikakhulukazi i-bellows seal efakwe i-fluorine plastic regulating valve, i-globe valve. Ngenxa yokuthi ama-bellows ayenziwe ngezinto ze-tetrafluoric, umehluko wengcindezi nokucindezela mkhulu, okungaholela kalula ekuqhumeni kwe-bellows.
Bellows seal lined fluorine plastic elawula valve, ukusetshenziswa isimo ingcindezi, ingcindezi umehluko mkhulu, ingashintshwa ukuze PTFE ukupakisha uphawu.
4. Isimo esimaphakathi sevalvu yepulasitiki enomugqa we-fluorine akufanele sibe nezinhlayiya eziqinile, amakristalu, ukungcola, njll., ukuze kungagugi umgogodla we-valve nesihlalo se-valve esifakwe ungqimba lwepulasitiki lwe-fluorine noma izivunguvungu ze-PTFE ekusebenzeni kokuvula nokuvala. I-medium inezinhlayiya ezinzima, amakristalu, ukungcola, ukukhetha, i-spool, isihlalo singasetshenziswa ku-Hastelloy.
I-5, efakwe ivalvu elawulayo yepulasitiki ye-fluorine kufanele ihambisane nokugeleza okudingekayo (inani le-Cv) ukukhetha okulungile kosayizi wobubanzi be-valve. Lapho ukhetha, uma ngokwesidingo sethrafikhi (i-Cv) kanye neminye imingcele yobuchwepheshe kubalwa usayizi we-valve kufanele kukhethwe futhi ukuvulwa kwe-valve, njengosayizi we-valve enkulu kakhulu, ngokuqinisekile kuzokwenza i-valve ekuvuleni isikhathi eside. isikhathi sisebenza, ngaphansi kwesimo sokucindezela okuncane nokuphakathi, kulula kakhulu ukwenza umgogodla we-valve nenduku ye-valve ngomthelela wabezindaba futhi wenze i-valve idlidlize, I-valve core rod in the medium isikhathi eside ngaphansi komthelela, ngisho izokwenza i-valve stem fracture.
