Ezweni eliyinkimbinkimbi lezinhlelo zokulawula uketshezi, ukusebenza nokusebenza kahle kwamavalvu ovemvane kuncike kakhulu ekukhetheni izinto zezihlalo zamavalvu. Lesi sihloko sidingida umehluko phakathi kwezinto ezimbili eziphambili ezisetshenziswa kulezi zinhlelo zokusebenza: i-PTFE ne-EPDM. Sizohlola izakhiwo zabo ezithile, izinhlelo zokusebenza, nokufaneleka ezindaweni ezihlukene 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
Esinye sezici ezivelele ze-PTFE yikhono layo lokugcina ukusebenza emazingeni okushisa aphezulu. I-PTFE ingakwazi ukumelana namazinga okushisa afika ku-260°C, iyenze ifaneleke izindawo lapho ukuguquka kwezinga lokushisa kubalulekile. Lokhu kuqina kuqinisekisa ukuphila isikhathi eside futhi kunciphisa isidingo sokunakekelwa njalo, okubalulekile ekugcineni ukusebenza okuqhubekayo kuzilungiselelo ezinzima.
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 ne-EPDM emanzini nesitimu akunakuqhathaniswa, okuyenza ibe wusizo ikakhulukazi ezinhlelweni ezinjengokuhlanza amanzi kanye nezinhlelo ze-HVAC. Ukunwebeka kwayo kunikeza uphawu oluhle, oluvumela ukungahambi kahle okuncane esihlalweni se-valve, okunomthelela ekuqina kwayo nokuthembeka ezinhlelweni eziguquguqukayo.
Ukusebenza Ezimweni Ezinolaka Lwekhemikhali
● Ukufaneleka kwe-PTFE Kwamakhemikhali Aqinile
Ukumelana namakhemikhali okukhethekile kwe-PTFE kuyenza iqonde-kuya okokusebenza kwezindawo eziphethe amakhemikhali anolaka. Lesi sakhiwo siqinisekisa ukuthi izihlalo zamavalvu e-PTFE zingakwazi ukugcina ubuqotho nokusebenza ngisho nalapho zingaphansi kwezinqubo zamakhemikhali ezinokhahlo, ezibaluleke kakhulu ezimbonini ezifana nokucubungula amakhemikhali kanye nowoyela 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
Ukuzinza okushisayo okuqinile kwe-PTFE kuyenza ibe ukukhetha okuhle kakhulu kwezinhlelo zokusebenza zezinga lokushisa eliphezulu. Kungakhathaliseki ukuthi kusezimbonini zamakhemikhali noma ezimbonini ezilungisa ukudla, ikhono le-PTFE lokusingatha amazinga okushisa adlulele ngaphandle kokulahlekelwa ubuqotho besakhiwo liqinisekisa ukuthi izihlalo zamavalvu zihlala zisebenza futhi zithembekile.
● Ukuqhathaniswa ne-EPDM's Temperature Range
I-EPDM, ngenkathi iguquguquka, inomkhawulo ophansi wezinga lokushisa uma iqhathaniswa ne-PTFE. Ivamise ukumelana namazinga okushisa afika ku-120°C, okwenza ingalungeli kakhulu izinhlelo ezifaka ukushisa okuphezulu. Nokho, ezilungiselelweni zokushisa ezimaphakathi, i-EPDM inikeza ukusebenza okwanele.
Izicelo Zifanele izihlalo zeValve ye-EPDM
● I-EPDM ku-Water and Steam Systems
Ukuqina kwe-EPDM emanzini kanye nokuchayeka kwesitimu kuyenza ibe wusizo ezinhlelweni lapho lezi zakhi zivelele khona. Lokhu kufaka phakathi izinhlelo zokusebenza ezifana nokuphathwa kwamanzi, amasistimu e-HVAC, nezinye izimboni lapho ubumanzi buhlala bukhona.
● Izinzuzo Ezindaweni Okungezona-Amakhemikhali
Ngale nje kwamanzi nesitimu, ukuguquguquka nokuqina kwe-EPDM kuyenza ifanelekele uhla lwezindawo okungezona - zamakhemikhali lapho uphawu oluthembekile lubalulekile. Ukunwebeka kwayo kanye nokumelana nezimo zemvelo njengemisebe ye-UV yengeza ekwazini kwayo izinto ezihlukahlukene.
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 Nezimo Eziqondile Zokusebenzisa
Naphezu kokuguquguquka kancane, imvelo eqinile ye-PTFE inenzuzo ezinhlelweni ezidinga ukunemba okuphezulu nokuzinza. Indawo yayo engeyona - induku kanye nokungqubuzana okuphansi nakho kunomthelela ekusetshenzisweni kwayo okuhlukile ezinqubweni 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
Isondlo singesinye isici esibalulekile. Ukumelana nokugqwala kwe-PTFE kunciphisa imvamisa yokulungisa futhi kuthuthukisa impilo yonke yezihlalo zamavalvu. I-EPDM iphinde inikeze impilo ende kodwa ingase idinge ukuhlolwa okuvamile ezindaweni ezisebenza ngamakhemikhali ukuze kuqinisekiswe ukwethembeka 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 kunqunywa phakathi kwe-PTFE ne-EPDM yezihlalo zamavalvu, izici ezimbalwa okufanele zicatshangelwe: uhlobo lwemidiya elawulwayo, izinga lokushisa elisebenzayo, izithiyo zezindleko, kanye nezimfuneko ezithile zohlelo lokusebenza lwemboni.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.
