Intsingiselo yophuhliso kunye nomngeni wabenzi bevalvu ye-PTFE

Njengemveliso yevalvu ephezulu, i-PTFE efakwe ivalve inethuba elibanzi losetyenziso kwimarike yaseTshayina. Ngophuhliso oluqhubekayo lwecandelo loshishino, imfuno yentengiso yeevalvu ze-PTFE iye yanda unyaka nonyaka. Nangona kunjalo, kwinkqubo yophuhliso, abavelisi bevalve ye-PTFE bajongene nemingeni emininzi. Eli phepha liza kuhlalutya iindlela zophuhliso kunye nemingeni yabavelisi be-PTFE iivalve ezinemigca. Okokuqala, intsingiselo yophuhliso 1. Ubuchule obutsha bobuchwephesha: Ngophuculo oluqhubekayo lwemfuno yemarike, abavelisi bevalvu ye-PTFE baya kwandisa utyalo-mali kuphando lweteknoloji nophuhliso, baphucule ukusebenza kwemveliso, kwaye baphucule inqanaba lobugcisa lilonke kushishino. Umzekelo, uphuhliso lwezinto ezikwazi ukumelana nokunxiba, ukumelana nokudleka okungaphezulu, i-coefficient esezantsi yokukhuhlana kwezinto ezinemigca ye-PTFE ukuhlangabezana nemfuno yabathengi beevalvu ezinemigca ye-PTFE esebenza kakhulu. 2. Ukuphuculwa komgangatho wemveliso: Kukhuphiswano lweemarike, abavelisi be-valve be-PTFE baya kuhlawula ngakumbi umgangatho wemveliso, ukuphucula ukuthembeka kwemveliso, ukuzinza kunye nokuqina, ukuze bahlangabezane neemfuno eziphezulu zabathengi. Oku kuya kukhuthaza abavelisi ukuba baphucule iinkqubo zemveliso, baphucule uyilo lwemveliso kunye nokwandisa ukhetho lwamalungu. 3. Ukwandiswa kwentsimi yesicelo: Intsimi yesicelo se-PTFE i-valve ene-lined yandisiwe ukusuka kwimichiza yendabuko, i-petroleum kunye namanye amashishini ukuya kumashishini asakhulayo afana ne-electronics, amayeza, kunye nokutya, kwaye imfuno yemarike iyahlukahluka kakhulu. Abavelisi bevalvu ye-Ptfe baya kuhlala behambisana notshintsho kwimfuno yentengiso kwaye baqhubeke nokuphuhlisa iimveliso ezintsha ezilungelelanisa amashishini ahlukeneyo kunye neemeko ezahlukeneyo zesicelo. 4. Uphuhliso lohlaza lokukhuselwa kokusingqongileyo: Ngengqalelo yelizwe ekukhuselweni kwendalo, abavelisi bevalvu ye-PTFE baya kunika ingqwalasela engakumbi ekusebenzeni kokusingqongileyo kweemveliso, baphucule umgangatho oluhlaza kunye nophantsi we-carbonization yeemveliso. Ngokomzekelo, uphando kunye nophuhliso lobuchwepheshe bokunciphisa ukusetyenziswa kwamandla kunye nokukhutshwa kwezinto ezingcolileyo kwinkqubo yokuvelisa, kunye nokusetyenziswa kwezinto ezinokuphinda zisetyenziswe kunye ne-degradable tetrafluorofluorocarbon-lined materials. Ii. Imingeni 1. Ukhuphiswano lwemarike luqinisa: Ngokunyuka okuqhubekayo kwemarike yevalve ye-PTFE, inani labavelisi liya likhula ngokuthe ngcembe, kwaye ukhuphiswano lwemarike luya lusiba nzima. Kule meko, abavelisi bevalvu ye-PTFE kufuneka banyuse utyalo-mali kuphando lwetekhnoloji kunye nophuhliso, baphucule umgangatho wemveliso, ukwenzela ukwandisa ukhuphiswano lwemarike. 2. I-phenomenon ye-homogeneity yemveliso inzulu: okwangoku, kukho inani elikhulu leemveliso ezilinganayo kwiimarike, ezikhokelela ekukhuphisaneni kweemarike. Abavelisi bevalvu ye-Ptfe kufuneka baphucule uphando lwemveliso kunye nesakhono sophuhliso kwaye baphuhlise iimveliso ezintsha ezineengenelo ezikhuphisanayo ezahlukeneyo ukulahla ukhuphiswano lwe-homogenized. 3. Ukwahluka kwemfuno yabathengi: Ngokwahlukana kwemfuno yabathengi ye-PTFE i-valve ene-lined, abavelisi kufuneka baqhubeke bephucula izakhono zokwenza imveliso ukuhlangabezana neemfuno zabathengi kwiimeko ezahlukeneyo zesicelo kunye neemeko zokusebenza ezahlukeneyo. 4. Ukuguquguquka kwamaxabiso ezinto eziluhlaza: eyona nto iphambili yeevalvu ze-teflon lined yi-polytetrafluoroethylene, kwaye ixabiso layo lichaphazeleka kakhulu kwiimarike zamazwe ngamazwe, amaxabiso e-oyile kunye nezinye izinto. Ngoko ke, abavelisi kufuneka bomeleze ulawulo lomngcipheko wexabiso lezinto eziphathekayo ukuzinzisa iindleko zemveliso. 5. Imigangatho yoShishino kunye neemfuno zolawulo: Ngokujongwa ngokungqongqo ngakumbi kwishishini levalve ye-PTFE ekhaya nakwamanye amazwe, abavelisi kufuneka bathathele ingqalelo utshintsho kwimigangatho yoshishino kunye nemimiselo yokuqinisekisa ukuba iimveliso ziyahlangabezana neemfuno ezifanelekileyo kwaye ziphephe imingcipheko yemveliso kunye neentengiso ezibangelwayo. ngokwaphulwa. Isishwankathelo, kwinkqubo yophuhliso, abavelisi be-valve ye-PTFE bajongene nokuveliswa kwezinto ezintsha zobuchwepheshe, ukuphuculwa komgangatho wemveliso, ukwandiswa kwentsimi yesicelo kunye nokukhusela okusingqongileyo okuluhlaza kunye nezinye iindlela zophuhliso, kodwa zijongene nemingeni yokuqinisa ukhuphiswano lwemarike, i-homogenization yemveliso, ukuhlukahluka kweemfuno zabathengi. , ukuguquguquka kwexabiso lempahla ekrwada kunye nemigangatho yoshishino kunye nemimiselo. Kwinkqubo yokuphendula le mingeni, abavelisi be-valve ye-PTFE kufuneka baqhubeke bephucula amandla abo abanzi ukuze baqhelane notshintsho lwemarike kunye nokufezekisa uphuhliso oluzinzileyo.
