Zingaki izinyathelo zokuphepha ozaziyo lapho ufaka ama-valve? Amaphuzu okunakwa ekusetshenzisweni kwe-fluorine ene-plastic anticorrosive valve ene-fluorine Lapho i-valve ifakiwe, ukuze kuvinjelwe insimbi, isihlabathi kanye nezinye izindikimba zangaphandle ekuhlaseleni i-valve futhi zilimaze indawo yokuvala, kuyadingeka ukusetha isihlungi kanye ne-valve yokushaywa; Ukuze ulondoloze ukuhlanzwa komoya ocindezelweyo, ngaphambi kwe-valve kudingeka ukusetha isihlukanisi samanzi samafutha, noma isihlungi somoya; Ukuhlola isimo sokusebenza se-valve ngesikhathi sokusebenza, kuyadingeka ukusetha ithuluzi futhi uhlole i-valve; Ukuze ulondoloze izinga lokushisa lokusebenza, faka i-insulation ngaphandle kwe-valve; Ukuze kufakwe i-post-valve, i-valve yokusiza noma i-valve yokuhlola...... iyadingeka Lapho i-valve ifakiwe, ukuze kuvinjelwe insimbi, isihlabathi kanye nezinye imizimba yangaphandle ekuhlaseleni i-valve futhi kulimaze indawo yokuvala, kuyadingeka. ukusetha isihlungi kanye ne-valve yokushaywa; Ukuze ulondoloze ukuhlanzwa komoya ocindezelweyo, ngaphambi kwe-valve kudingeka ukusetha isihlukanisi samanzi samafutha, noma isihlungi somoya; Ukuhlola isimo sokusebenza se-valve ngesikhathi sokusebenza, kuyadingeka ukusetha ithuluzi futhi uhlole i-valve; Ukuze ulondoloze izinga lokushisa lokusebenza, faka i-insulation ngaphandle kwe-valve; Ukufakwa ngemuva kwe-valve, udinga ukusetha i-valve yokuphepha noma i-valve yokuhlola; Uma kucatshangelwa ukusebenza okuqhubekayo kwe-valve, elungele ingozi, setha uhlelo oluhambisanayo noma uhlelo lokudlula. 1. Izinsiza zokuzivikela zama-valve okuhlola: Ukuze kuvinjwe ukuvuza kwama-valve okuhlola noma ukugeleza emuva kwemidiya ngemva kokwehluleka, okuholela ekuwohlokeni kwekhwalithi yomkhiqizo kanye nezingozi, i-valve yokusika eyodwa noma amabili abekwe ngaphambi nangemuva kwe-valve yokuhlola. Uma ama-valve amabili okuvala enikezwa, i-valve yokuhlola ingasuswa kalula ukuze isebenze. Izinsiza zokuvikela i-valve yokuphepha ye-2: ngaphambi nangemva kwendlela yokufaka ngokuvamile ayisethiwe i-valve yokuvimba, kuphela ezimweni ezingazodwana, 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 izinto zemidiya kuzinga lokushisa elilingana negumbi lesimo esiqinile, noma ukunciphisa i-gasification yengcindezi kanye nezinga lokushisa eliphakathi nendawo eliwuketshezi elilula lingaphansi 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. 3. Izinsiza zokuzivikela zama-valve okunciphisa ingcindezi: ngokuvamile kunezinhlobo ezintathu zezindawo zokufakela ama-valve okunciphisa ingcindezi. 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. 4. Izinsiza zokuzivikela zomgibe: kunezinhlobo ezimbili zepayipi ye-bypass kanye nepayipi ye-bypass emaphethelweni ogibe, ukubuyiswa kwe-condensate kanye ne-condensate hhayi ukukhokhelwa kokubuyisela, ukukhishwa kanye nezinye izidingo ezikhethekile zesicupho, zingafakwa ngokufana. Isicupho esinevalve yokudlula sisetshenziswa kakhulukazi 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 le-bypass. Amaphuzu okunakwa ekusetshenzisweni kwe-fluorine ene-plastic anticorrosive valve I-fluorine ene-plastic anti-corrosion valve ku-petroleum, imboni yamakhemikhali, imithi, i-metallurgy, amandla kagesi nezinye izimboni zokuthintana ne-asidi kanye ne-alkali kanye nezinye izisetshenziswa eziqinile zemidiya ezonakalisayo kube isicelo esingcono kakhulu, kodwa indlela yokukhetha okuhle, ukusetshenziswa kahle kwe-fluorine i-valve yepulasitiki efakwe umugqa, ngokusho kwabasebenzisi bethu phakathi neminyaka yokuhlangenwe nakho kwesicelo sensimu, lezi zinyathelo zokuphepha ezilandelayo kufanele zibekwe phambili ukuze kusetshenziswe izinga lokushisa eliphakathi, ingcindezi, umehluko wengcindezi nezinye izimo lapho i-fluorine ene-anti-corrosion valve ikhethiwe: 1, izinga lokushisa eliphakathi kwe-fluorine eline-fluorine lined plastic: Izinhlobo ezihlukahlukene zenkampani yethu zama-valve epulasitiki ane-fluorine, ukusetshenziswa kwepulasitiki ye-fluorine yi-F46 (FEP), ukusetshenziswa kwezinga lokushisa eliphakathi akukwazi ukudlula i-150 ℃ (izinga lokushisa eliphakathi nendawo lingaba ngu-150 ℃ isikhathi esifushane, izinga lokushisa lokusetshenziswa kwesikhathi eside kufanele lilawulwe ku-120 ℃), ngaphandle kwalokho, izingxenye ze-valve ezifakwe ku-F46 kulula ukuthambisa, ukuguquguquka, 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. Abasebenzisi ekukhethweni kwazo zonke izinhlobo zama-valve epulasitiki ane-fluorine, kufanele kube ngangokunokwenzeka ukuqonda, ukuqonda ukusetshenziswa kwezimo zobuchwepheshe, ukuze ukhethe, usebenzise kahle, uthuthukise impilo yesevisi ye-valve. Uma ingaphezu kobubanzi bezimo zobuchwepheshe, kufanele iphakanyiswe kumkhiqizi, futhi izinyathelo zokuphikisana nazo kufanele zithathwe ukuze kuxazululwe inkinga ngokubonisana ngokuhlanganyela.
