Kwilizwe elinengxaki lenkqubo yokulawula iinkqubo, ukusebenza kunye nokusebenza kakuhle kweevalve zebhabhathane hinge ngokukhetha izitulo zevali. Eli nqaku lidla ngokuphazamiseka phakathi kwezinto ezimbini eziphambili ezisetyenziswa kwezi zicelo: Ptfe ne-EPDM. Siza kuphonononga iipropathi zabo, izicelo, kunye nokufaneleka kwiindawo ezahlukeneyo zoqoqosho.
Isingeniso kwiZitulo zeValve: PTFE kunye ne-EPDM
● Isishwankathelo seZitulo zeValve kwizicelo zoShishino
Izihlalo zevalvu zizinto ezibalulekileyo ekusebenzeni kweevalvu zebhabhathane, ezidlala indima ebalulekileyo ekutywineni nasekuqinisekiseni ukuba isivalo sisebenza ngokufanelekileyo. Ukuqulunqwa kwezinto zabo kuchaphazela ngokuthe ngqo ukusebenza kwabo, ixesha elide, kunye nokufaneleka kwezicelo ezahlukeneyo zemizi-mveliso. I-PTFE (i-Polytetrafluoroethylene) kunye ne-EPDM (i-Ethylene Propylene Diene Monomer) ziphakathi kwezinto ezisetyenziswa kakhulu ngenxa yeempawu zabo ezahlukileyo.
● Ukubaluleka Kokukhetha Izinto
Ukukhetha isitulo esifanelekileyo sevalve kubalulekile ekuqinisekiseni ukusebenza kwevalvu ngeyona ndlela kunye nokusebenza kakuhle kwenkqubo. Izinto eziphathekayo kufuneka zimelane neemeko ezithile zokusebenza kwaye zibambe iintlobo ezithile zamanzi okanye iigesi ezidibana nazo kwinkqubo. Kulo mongo, ukuqonda iipropati kunye nokusetyenziswa kwe-PTFE kunye ne-EPDM kuba yinto ebalulekileyo kuye nabani na obandakanyekayo kwi-teknoloji yokulawula ulwelo.
Ukubunjwa kwezinto eziphathekayo kunye neePropati ze-PTFE
● Ubume beMichiza kunye neempawu ze-PTFE
I-PTFE yifluoropolymer yokwenziwa eyaziwa ngokumangalisayo ukungenzi-reactivity, uzinzo oluphezulu lwe-thermal, kunye nokukhuhlane okuphantsi. Oku kudityaniswa kweepropati kwenza i-PTFE ibe yimathiriyeli efanelekileyo yezihlalo zevalvu kwizicelo ezibandakanya iikhemikhali ezinobundlobongela kunye nobushushu obugqithisileyo. Ubume bayo beekhemikhali bubonelela ngokumelana neekhemikhali ezingenakuthelekiswa nanto, okwenza ukuba ikhuseleke kwizinto ezitshabalalisayo ezinokuthi zithobe ezinye izinto.
● Ukuxhathisa kweqondo lobushushu kunye noKuhlala ixesha elide
Enye yeempawu zokuzimela kwe-ptfe kukukwazi ukugcina intsebenzo kumaqondo obushushu aphezulu. I-PTFE inokumelana namaqondo obushushu ukuya kwi-260 ° C, eyenza ilungele iimeko apho ithuba lokuhamba kwamaqondo lubaluleke kakhulu. Oku kunyuka kuqinisekisa ukuba i-longeving iqinisekise kwaye kunciphisa isidingo solondolozo rhoqo, kubaluleke kakhulu ukugcina imisebenzi eqhubekayo kwizicwangciso.

UkuPhathwa koBubushushu bezakhono ze-PTFE
● Phezulu-Ubushushu bezicelo ze-PTFE
Uzinzo lwe-therm lomeleleyo lwe-PTFO lwenza ukuba lukhetho oluhle kakhulu - Izicelo zobushushu. Nokuba kwizityalo zekhemikhali okanye amashishini okutya ukutya, amandla e-PTPO yokujongana nobushushu obuthe gabalala ngaphandle kokuphulukana nokunyaniseka kwayo kuqinisekisa ukuba izitulo zevali zihlala zisebenza kwaye zithembekile.
● uthelekiso olunodidi lobushushu lwe-EPDM
I-EPDM, ngelixa uguquguqukayo, inomqobo wobushushu ophantsi xa kuthelekiswa nePTFE. Ngokwesiqhelo inameko kwiintsilelo ukuya kuthi ga kwi-120 ° C, ethi iyenza ilungele izicelo ezibandakanya ubushushu obuphezulu. Nangona kunjalo, kusondela ophakathi kweqondo lokushisa, i-EPDM inika intsebenzo eyaneleyo.
Usetyenziso olufanele iZitulo zeValve ye-EPDM
● I-EPDM kwiiNkqubo zaManzi kunye ne-Steam
Ukomelela kuka-Epdm kumanzi kunye nokuvezwa kweSteam kwenza ukuba kube yinyani kwiinkqubo apho ezi zinto zihamba phambili. Oku kubandakanya izicelo ezinje ngolawulo lwamanzi, iinkqubo ze-HVAC, kunye namanye amashishini apho ubukho bomswakama buhlala buhleli.
● Izinto eziluncedo kwindawo engeyiyo - yeMichiza
Ngaphaya nje kwamanzi kunye ne-Steam, ukuguquguquka kuka-EPDM kwaye ukuqina kwenze ilungele uluhlu lwezinto ezingezizo iichemical apho itywina lemichiza apho itywina elinokuthenjwa libalulekile. Ukuqina kwayo kunye nokuxhathisa kwiimeko zokusingqongileyo ezinje ngemitha ye-UV yongeza ukuya phambili.
Ukuthelekisa ukuguquguquka kunye nokuguquguquka
