Teflon lined valvụ bụ valvụ nke na-eji polytetrafluoroethylene (PTFE, nke a makwaara dị ka Teflon) dị ka ihe mkpuchi, a na-ejikwa ya n'ọtụtụ ebe n'ihi uru ọrụ ya pụrụ iche. Akwụkwọ a ga-ewebata uru arụmọrụ na mpaghara ngwa nke valvụ eriri anọ nwere fluorine.
Nke mbụ, uru arụmọrụ nke valves PTFE
1. Magburu onwe corrosion eguzogide: akara n'elu nke teflon valvụ bụ nke polytetrafluoroethylene ihe, nke nwere oké elu chemical nkwụsi ike na ike iguzogide corrosion nke ọtụtụ chemical media, gụnyere ike acid, alkali, organic solvents, wdg, ya mere ọ na-arụ ọrụ. nke ọma na ubi nke corrosive media njem.
2. Ọnụ ọgụgụ dị ala nke esemokwu: PTFE nwere ọnụ ọgụgụ dị ala nke esemokwu (0.05-0.1), nke na-eme ka valvụ PTFE nwee ike nweta mmegharị dị nro n'oge mmeghe na mmechi, na-ebelata ike na-arụ ọrụ na ibelata ike ike nke akụrụngwa.
3. Mgbochi viscosity: polytetrafluoroethylene nwere ezigbo mgbochi viscosity, nke nwere ike igbochi ihe ahụ ka ọ ghara ịrapara n'elu ihe mkpuchi ma belata ọrụ mmezi nke valve.
4. Ọnọdụ okpomọkụ: ihe mkpuchi nke PTFE lined valve nwere ike ịrụ ọrụ na nso -200 ° C ruo 260 Celsius C ruo ogologo oge, ma nwee ike ịnagide okpomọkụ dị elu n'oge dị mkpirikpi, nke na-eme ka PTFE lined valve nwere ike ịbụ. etinyere na ọnọdụ okpomọkụ dị iche iche.
5. Ọrụ nchekwa: N'ihi na valve anọ nke fluorine na-eji ihe ndị na-abụghị ọla dị ka ihe mkpuchi, ọ gaghị emepụta ihe ndị na-emerụ ahụ ọbụna n'okpuru ọnọdụ dị oke egwu dị ka okpomọkụ dị elu na nrụgide dị elu, ya mere ọ nwere nnukwu ọrụ nchekwa.
Nke abụọ, mpaghara ngwa ngwa nke valves PTFE lined
1. Chemical ụlọ ọrụ: PTFE lined valves na-ọtụtụ ebe na-eji na chemical ụlọ ọrụ, karịsịa na corrosive media, ike acid na alkali gburugburu, PTFE lined valves nwere ike hụ na nchekwa ọrụ nke ngwá na ibelata mmezi ụgwọ.
2. Ụlọ ọrụ mmanụ ala: N'ime ụlọ ọrụ mmanụ ala, PTFE lined valves na-ejikarị ebu mmanụ, gas gas na mgbasa ozi ndị ọzọ, na njedebe ya dị oke mma na njedebe na-eme ka PTFE lined valves bụrụ valvụ kachasị mma na ụlọ ọrụ mmanụ ala.
3. Ụlọ ọrụ na-emepụta ọgwụ: Ụlọ ọrụ na-emepụta ọgwụ nwere ihe dị elu chọrọ maka ịdị ọcha na nchekwa nke akụrụngwa, na valvụ tetrafluorolined na-emezu ihe ndị a chọrọ, ya mere a na-eji ya eme ihe na ụlọ ọrụ ọgwụ.
4. Eletrọnịkị ụlọ ọrụ: Ngwa nke PTFE lined valves na ụlọ ọrụ eletrọnịkị na-egosipụtakarị na nnyefe na njikwa nke ikuku dị ọcha na mmiri mmiri, na arụmọrụ ya dị mma nwere ike hụ na arụ ọrụ nke ngwa eletriki siri ike.
6. Ụlọ ọrụ nri: N'ihi ezigbo mgbochi viscosity na mgbochi corrosion nke PTFE lined valves, a na-ejikwa ha mee ihe n'ọtụtụ ebe na ụlọ ọrụ nri, dị ka arụmọrụ magburu onwe ya na-ebuga mgbasa ozi dị elu dị ka sirop na ihe ọṅụṅụ.
Na nchịkọta, PTFE lined valves ejiriwo ọtụtụ ebe n'ọtụtụ ebe site na uru arụmọrụ ha dị mma. Site na mmepe nke sayensị na teknụzụ na-aga n'ihu, mpaghara ngwa nke PTFE lined valves ga-agbasawanye n'ọdịnihu.
