Izinyathelo zokuzivikela okufanele zinakwe lapho kufakwa isingeniso se-valve fluorine lining anti-corrosion valve

Lapho i-valve ifakiwe, ukuze kuvinjelwe insimbi, isihlabathi kanye nezinye izindikimba zangaphandle ekuhlaseleni i-valve futhi zilimaze indawo yokubeka uphawu, kuyadingeka ukusetha isihlungi kanye ne-valve yokudonsa; Ukuze ulondoloze ukuhlanzwa komoya ocindezelweyo, ngaphambi kwe-valve kudingeka ukusetha isihlukanisi samanzi samafutha, noma isihlungi somoya; Ukuze uhlole 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-valve ye-bypass 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 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 le-bypass.
I-valve ye-antiseptic ye-fluorine-butterfly yethulwa ama-valve e-Fluorine-butterfly eyaziwa nangokuthi i-lining fluorine plastic corrosion valve, izosebenzisa indlela ye-ptfe resin (noma isethi) ebunjiwe, ku-valve yokucindezela odongeni noma ngaphandle kwezingxenye zangaphakathi ze-valve, (indlela efanayo iyasebenza kuzo zonke izinhlobo zomkhumbi ocindezelayo kanye nokufakwa kwamapayipi), kusetshenziswa izici zayo eziyingqayizivele mayelana nokumelana okuqinile nesistimu ephakathi kokugqwala eyenziwe nge-valve emelana nokugqwala * *.
Ivalvu efakwe i-fluorine, isingeniso se-valve engagqwali:
Amavalvu e-fluorine-butterfly aziwa nangokuthi i-lining fluorine plastic corrosion valve, izosebenzisa indlela ebunjiwe ye-ptfe resin (noma isethi), ku-valve yokucindezela odongeni noma ngaphandle kwezingxenye zangaphakathi ze-valve, (indlela efanayo iyasebenza zonke izinhlobo zomkhumbi ocindezelayo kanye nokufakwa kwamapayipi), kusetshenziswa izakhiwo zawo ezihlukile mayelana nokumelana okuqinile nesistimu yokugqwala eyenziwe nge-valve engu- * * engagqwali. Ngamagama alula, ama-valve ane-fluorine afakwe umugqa wonke abekwe ezingeni lapho okuphakathi emzimbeni we-valve kungafinyelela khona.
Indwangu ye-fluorine lined valve ngokuvamile i-FEP(F46) kanye ne-PCTFE(F3) namanye amapulasitiki e-fluorine, angasetshenziswa ekugxilweni okuhlukahlukene kwe-sulfuric acid, i-hydrochloric acid, i-hydrofluoric acid, i-aqua aqua kanye ne-organic acid ehlukahlukene, ama-acids aqinile, ama-oxidants aqinile namanye amapayipi emidiya agqwalayo, kodwa ivalvu elayishiwe ye-fluorine inqunyelwe izinga lokushisa, isebenza kuphela endaweni ephakathi nendawo ephakathi -50℃ no-150℃.
I-valve ene-fluorine, ukuhlukaniswa kwe-valve ukumelana nokugqwala:
Ama-valve epulasitiki e-fluorine avamile yilawa: i-fluorine lined butterfly valve, i-fluorine lined ball valve, i-fluorine lined globe valve, i-fluorine lined diaphragm valve, i-fluorine lined gate valve, i-fluorine lined plug valve, njll.
1, i-fluorine efakwe i-valve yebhola
IZIMPAWU Zemishini, izakhiwo zikagesi nokuzinza kwamakhemikhali ngokuyisisekelo ziyafana ne-F4, kodwa izinzuzo ezivelele ziwukuqina okuphezulu okuguquguqukayo, ukumelana nesimo sezulu esihle kakhulu kanye nemisebe.
2, ivalve uvemvane ene-fluorine
Ama-valve e-fluorine-butterfly
Kusetshenziswa lapho ukubekwa uphawu okuthembekile kanye nezici zokulawula ezinhle zidingeka. Umzimba we-valve uvemvane one-fluorine wamukela uhlobo oluhlukanisiwe, ukuvalwa kwe-valve shaft kulawulwa yirabha ejikelezayo ye-fluorinated rubber phakathi kwepuleti levemvane nesihlalo, ukuze kuzuzwe isakhiwo somkhiqizo ohlangene, ukubukeka okuhle, ubuchwepheshe obunengqondo nokusebenza okuthembekile. I-valve ye-butterfly ene-fluorine iqinisekisa ukuthi i-valve shaft ayixhumani nendawo yoketshezi ekamelweni. Kulula kakhulu ukufaka esikhundleni se-valve shaft. I-valve uvemvane ene-fluorine ingaqedwa ngaphandle kokunqamula ipayipi.
3, ivalve yesango ene-fluorine
Uhlobo lwe-valve evulekile nevalekile ebonakalayo, ukusetshenziswa kwepuleti lesango elimise okwesikele ezinhlangothini ezimbili ukuxhuma noma ukunqamula okuphakathi epayipini, i-valve yesango eliwucezu ayikuvumeli ukuvuleka komkhondo epayipini njengomshini wokudonsa umoya, ukuze gwema ukugeleza kwesivinini esikhulu sokuguguleka okuphakathi futhi usheshise ukulimala kwendawo yokuvala.
4, i-fluorine ipulaki valve
Isakhiwo esiqinile futhi esinengqondo, isikhala somgodi we-valve sincane, sinciphisa ukugcinwa okuphakathi, ngaphezu kwalokho, inqubo ekhethekile yokubumba, ukuze ukuminyana kwendawo yokubeka uphawu kuhle, kuhlanganiswe nenhlanganisela yokupakisha ye-herringbone PTFE, ukuze i-valve ifinyelele ukuvuza kwe-zero; Lolu chungechunge luklanyelwe ukuvula nokuvala okuzenzakalelayo kwazo zonke izinhlobo zamapayipi emidiya agqwala kakhulu.
5, i-fluorine ene-stop valve
Ngokuphakamisa i-valve disc ukwenza i-valve ivuleke noma ivinjwe, i-valve disc kanye nomzimba we-valve ngaphakathi zonke zenziwe nge-fluorine plastic linening plastic process, enezinzuzo zokushintshwa kokukhanya, usayizi omncane, ukubeka uphawu okuthembekile, isakhiwo esilula, ukugcinwa okulula, ukusetshenziswa okubanzi, njll.
6. Ivalvu yokuhlola ene-fluorine
Isakhiwo siwuphawu oluthambile olunoxhumano oluphindwe kabili lwe-eccentric flange. Idivayisi evala kancane iklanywe ngaphandle kwevalvu yokuhlola uvemvane evala kancane ukumelana nokuvala kancane, esiza ukunciphisa ukumelana nokugeleza nokudlidliza, nokunciphisa umthelela wesando samanzi.
