Emhlabeni oyinkimbinkimbi wezinhlelo zokulawula uketshezi, umsebenzi kanye nokusebenza kahle kwama-butterfly valves HInge kakhulu ekukhetheni kwezinto zokwakha izihlalo ze-valve. Lo mbhalo ukhipha umehluko phakathi kwezinto ezimbili ezisetshenziswayo ezisetshenziswe kulezi zicelo: PTFE ne-EPDM. Sizohlola izakhiwo zabo ezithile, izinhlelo zokusebenza, kanye nokufaneleka ezindaweni ezahlukene zezimboni.
Isingeniso Sezihlalo zeValve: PTFE kanye ne-EPDM
● Uhlolojikelele lwezihlalo zevalvu kuzicelo zezimboni
Izihlalo zamavalvu ziyizingxenye ezibalulekile ekusebenzeni kwamavalvu ovemvane, ezidlala indima ebalulekile ekuvaleni nasekuqinisekiseni ukuthi amavalvu asebenza kahle. Ukwakheka kwazo okubalulekile kuthonya ngokuqondile ukusebenza kwazo, ukuphila isikhathi eside, nokufaneleka kwezinhlelo zokusebenza ezihlukene zezimboni. I-PTFE (Polytetrafluoroethylene) kanye ne-EPDM (Ethylene Propylene Diene Monomer) ziphakathi kwezinto ezisetshenziswa kakhulu ngenxa yezici zazo ezihlukile.
● Ukubaluleka Kokukhetha Okubalulekile
Ukukhetha impahla yesihlalo se-valve efanele kubalulekile ekuqinisekiseni ukusebenza kahle kwe-valve nokusebenza kahle kwesistimu. Okubalulekile kufanele kumelane nezimo ezithile zokusebenza futhi kuphathe izinhlobo ezithile zoketshezi noma amagesi okuhlangatshezwane nawo ohlelweni. Kulo mongo, ukuqonda izakhiwo nokusetshenziswa kwe-PTFE kanye ne-EPDM kubaluleka kunoma ubani obambe iqhaza kubuchwepheshe bokulawula uketshezi.
Ukubunjwa Okubalulekile kanye Nezakhiwo ze-PTFE
● Isakhiwo Sekhemikhali kanye Nezimpawu ze-PTFE
I-PTFE iyi-fluoropolymer yokwenziwa eyaziwa ngokungasebenzi kwayo kabusha okuphawulekayo, ukuzinza okuphezulu kokushisa, nokungqubuzana okuphansi. Le nhlanganisela yezakhiwo yenza i-PTFE ibe into efanelekile yezihlalo zamavalvu ezinhlelweni ezibandakanya amakhemikhali anolaka namazinga okushisa adlulele. Ukwakheka kwayo kwamakhemikhali kunikeza ukumelana namakhemikhali okungenakuqhathaniswa, okuyenza ivikeleke ezintweni ezigqwalayo ezingacekela phansi ezinye izinto.
● Ukumelana Nezinga Lokushisa Nokuqina
Enye yezinto zokusukuma ze-PTFE yikhono layo lokugcina ukusebenza emazingeni okushisa aphezulu. I-PTFE ingamelana namazinga okushisa aze afike ku-260 ° C, okwenza kwalungele izindawo lapho ukuguquguquka kwezinga lokushisa kubalulekile. Lokhu kuqina kuqinisekisa ukufisa isikhathi eside futhi kunciphisa isidingo sokulungiswa njalo, okubalulekile ukuze kugcinwe imisebenzi eqhubekayo kuzilungiselelo ezifunwayo.
Ukubunjwa Okubalulekile kanye Nezakhiwo ze-EPDM
● Isakhiwo Sekhemikhali kanye Nezimpawu ze-EPDM
I-EPDM iwuhlobo lwerabha yokwenziwa enokuqina okuhle kakhulu nokumelana nezimo zezulu ezahlukahlukene. Ukwakheka kwayo kwamakhemikhali kuvumela i-EPDM ukuthi yenze kahle kakhulu ezindaweni lapho ukuchayeka emanzini, umusi, nezinhlobonhlobo zamakhemikhali kuvame. Lesi sakhiwo sikwenza kube ukukhetha okuguquguqukayo kwezicelo eziningi zezimboni.
● Ukumelana Namanzi Nokunwebeka
Ukumelana nokuphikiswa kwe-EPDM kumanzi noSteam akunakuqhathaniswa, okwenza kube yinzuzo ezungu ngokukhethekile okufana nokwelashwa kwamanzi nezinhlelo ze-HVAC. I-elasticity yayo ihlinzeka ngophawu oluhle, ukuhlalisa okungahambi kahle esihlalweni se-valve, okunomthelela ekunciphiseni nasekuthembekeni kwalo ezinkundleni ezinamandla.
Ukusebenza Ezimweni Ezinolaka Lwekhemikhali
● Ukufaneleka kwe-PTFE kwamakhemikhali anokhahlo
Ukumelana kwamakhemikhali okuyingqayizivele kwe-PTFE kwenza kube yi-Go - Kuma-Material to Materials Ezenzweni Eziphathwa Amakhemikhali Anolaka. Le mpahla iqinisekisa ukuthi izihlalo ze-PTFE Valve zingagcina ukuthembeka nokusebenza noma ngabe zibhekene nezinqubo zamakhemikhali ezinzima, ezibalulekile ezimbonini ezinjengowoyela kanye negesi.
● Imikhawulo ye-EPDM Ekuvezeni Amakhemikhali
Nakuba i-EPDM imelana kakhulu namanzi nesitimu, ukusebenza kwayo kungaba sengozini ezindaweni ezihlanganisa amakhemikhali agqwala kakhulu. Ayinikezi izinga elifanayo lokumelana namakhemikhali njenge-PTFE, ekhawulela ukusebenziseka kwayo kuzilungiselelo ezinolaka lwamakhemikhali.
Amandla Okuphatha Izinga lokushisa we-PTFE
● High-Izinga lokushisa Izicelo ze-PTFE
Ukuqina okuqinile okushisayo kwe-PTFE kwenza kube ukukhetha okuhle kakhulu kokuphezulu - Izicelo zokushisa. Ukuthi ngabe yizitshalo zamakhemikhali noma izimboni zokudla zokudla, amandla e-PTFE okuphatha amazinga okushisa aphezulu ngaphandle kokulahlekelwa ubuqotho bayo obuhle kuqinisekisa ukuthi izihlalo ze-valve zihlala zisebenza futhi zithembekile.
● Ukuqhathanisa nebanga lokushisa le-EPDM
I-EPDM, ngenkathi iguquguqukayo, inombundu ophansi wokushisa uma uyiqhathaniswa ne-PTFE. Imvamisa ukumelana namazinga okushisa afinyelela ku-120 ° C, okwenza kungafaneleki kalula ukufaka isicelo esibandakanya ukushisa okuphezulu. Kodwa-ke, kuzilungiselelo zokushisa ezilinganiselayo, i-EPDM inikeza ukusebenza okwanele.
Izicelo Zifanele izihlalo zeValve ye-EPDM
● I-EPDM ku-Water and Steam Systems
Ukudalulwa kuka-Epdm ekuvezweni kwamanzi nokuvezwa kwe-Steam kwenza kube yinto ebaluleke kakhulu ezinhlelweni lapho lezi zinto zidlula khona. Lokhu kufaka phakathi izinhlelo zokusebenza ezinjengokuphathwa kwamanzi, izinhlelo ze-HVAC, kanye nezinye izimboni lapho ubukhona bomswakama buhlala bukhona.
● Izinzuzo Ezindaweni Okungezona-Amakhemikhali
Ngaphandle kwamanzi nje, ukuguquguquka kwe-EPDM, ukuqina kwe-EPDM nokuqina kwenza kube lula ukwahlukahluka kwendawo yamakhemikhali lapho kubalulekile khona uphawu oluthembekile. Ukuqina kwalo kanye nokumelana nezimo zemvelo ezinjenge-UV Radiation engeza ekuguquguqukeni kwayo.
Ukuqhathanisa Nokuvumelana nezimo
● Ukuvumelana nezimo kwe-EPDM kuma-Dynamic Systems
I-EPDM inikeza ukuguquguquka okukhulu kune-PTFE, okungaba yinzuzo kumasistimu angaphansi kokudlidliza noma ukunyakaza. Amandla ayo okonakala ngaphandle kokulahlekelwa amandla okuvala enza i-EPDM ibe ukukhetha okuphumelelayo ezinhlelweni ezihlukahlukene zezimboni ezinamandla.
● Ukuqina kwe-PTFE kanye namacala athile okusetshenziswa
Yize enobunzima obuncane, imvelo eqinile ye-PTFE inenzuzo ekusetshenzisweni okudinga ukunemba okuphezulu nokuqina. Okungaphezulu kwaso - indawo yokunamathela nokuxabana okuphansi nakho kufaka nokufaka isandla ekusetshenzisweni kwayo okuhlukile ezinhlelweni ezikhethekile zezimboni.
Izindleko Nokucatshangelwa Kwesondlo
● Izindleko Ezinde-Izindleko Zesikhathi Sazo Zombili Izinto
Lapho uhlola i-PTFE ne-EPDM, ukucatshangelwa kwezindleko kubalulekile. Nakuba i-PTFE ijwayele ukubiza izindleko zokuqala eziphakeme ngenxa yezakhiwo zayo nenqubo yokukhiqiza, ukuqina kwayo kungahumushela kukonga - I-EPDM, njengoba ibiza kakhulu-esebenza kahle ngaphambili, iseyindlela engenzeka ezinhlelweni zokusebenza lapho izakhiwo zayo zihambisana nezidingo zesistimu.
● Izidingo Zesondlo Nesikhathi Sokuphila
Ukulungiswa kungenye into ebalulekile. Ukumelana kukaPtfe kokugqwala nokugqoka kunciphisa imvamisa yesondlo futhi kuthuthukise isikhathi sokuphila kwezihlalo ze-valve. I-EPDM iphinde inikeze isikhathi sokuphila eside kepha ingadinga amasheke athe xaxa ezindaweni ezisebenza ngamakhemikhali ukuze aqinisekise ukuthembeka okuqhubekayo.
Ukuphepha Nokuhambisana Ekusetshenzisweni Kwezimboni
● Imithetho Yokuphepha ye-PTFE ne-EPDM
Kokubili i-PTFE ne-EPDM kufanele zihambisane nemithetho eqinile yokuphepha kwemboni, iqinisekise ukuthi zifanele izinhlelo zokusebenza ezisetshenziswa kuzo. Le mithetho yenzelwe ukuvimbela ukwehluleka futhi ivikele imisebenzi ngokumelene nokuvalwa okungalindelekile noma izingozi.
● Amazinga Embonini Nezitifiketi
Abakhiqizi bezinto ze-PTFE kanye ne-EPDM kufanele bathobele izindinganiso zomkhakha futhi bathole izitifiketi eziqinisekisa ikhwalithi nokusebenza kwemikhiqizo yabo kuzilungiselelo ezihlukahlukene zezimboni. Lokhu kuqinisekisa ukuthi abasebenzisi bokugcina bathola imikhiqizo ehlangabezana nemibandela yokusebenza edingekayo.
Isiphetho: Ukukhetha Phakathi kwe-PTFE ne-EPDM
● Isinqumo-Ukwenza Izinto Zokukhetha Isihlalo Sevalvu
Lapho unquma phakathi kwe-PTFE ne-EPDM yezihlalo ze-valve, kufanele kubhekwe izici eziningana: Uhlobo lwemidiya elawulwa, uhla lokushisa olusebenzayo, izingqinamba zezindleko, kanye nezidingo ezithile zohlelo lokusebenza lwezimboni. sanitary epdm+ptfe compound butterfly valve seats inikezela ngesixazululo esihlanganisiwe esisebenzisa izici ezihamba phambili zazo zombili izinto zokwakha, sinikeza inketho eguquguqukayo yezidingo ezahlukahlukene zezimboni.
● Izincomo Ngokusekelwe Ezidingweni Zohlelo
Ekugcineni, ukukhetha phakathi kwe-PTFE ne-EPDM kuzokwehla kuzidingo ezithile zohlelo lokusebenza. Ezindaweni ezinolaka lwamakhemikhali ezinezidingo zokushisa okuphezulu, i-PTFE ayinakuqhathaniswa. Kuzinhlelo zokusebenza ezibandakanya amanzi, isitimu, noma ezidinga ukunwebeka okuphezulu, i-EPDM ihlala ifaneleka kakhulu.
