Teflon lined valve ivharuvhu inoshandisa polytetrafluoroethylene (PTFE, inozivikanwawo seTeflon) sechinhu chekuisa chisimbiso, uye inoshandiswa zvakanyanya muminda yakawanda nekuda kwekuita kwayo kwakasiyana kwakanakira. Iri bepa richasuma mabhenefiti ekuita uye minda yekushandisa yechina-fluorine lined valve.
Kutanga, mabhenefiti ekuita kwePTFE mavharuvhu
1. Yakanakisa corrosion resistance: chisimbiso chepamusoro chevhavhavha ye teflon yakagadzirwa ne polytetrafluoroethylene zvinhu, iyo ine yakanyanya kugadzikana kwemakemikari uye inogona kudzivisa kuparara kwemakemikari akawanda emidhiya, kusanganisira yakasimba acids, alkali, organic solvents, nezvimwewo, saka inoita. zvakanaka mumunda wekuodza media transportation.
2. Yakaderera coefficient of friction: PTFE ine yakaderera yakaderera coefficient of friction (0.05-0.1), iyo inoita kuti PTFE valve ibudirire kufamba kwakadzikama panguva yekuvhura nekuvhara, kuderedza tambo yekushanda uye kuderedza kushandiswa kwesimba kwemichina.
3. Anti-viscosity: polytetrafluoroethylene ine anti-viscosity yakanaka, iyo inogona kudzivirira zvinhu kubva pakunamatira kune chisimbiso chepamusoro uye kuderedza basa rekuchengetedza revhavha.
4. Kuchinja kwekushisa: iyo yekuisa chisimbiso yePTFE lined valve inogona kushanda mukati me -200 ° C kusvika 260 ° C kwenguva yakareba, uye inogona kumira kutonhora kwepamusoro munguva pfupi, izvo zvinoita kuti PTFE vheji yakavharidzirwa inogona kuva. inoshandiswa kune dzakasiyana siyana tembiricha nharaunda.
5. Kuchengetedzwa kwekuchengetedza: Nokuti iyo ina-fluorine yakavharidzirwa valve inoshandisa zvinhu zvisiri zvesimbi sechisimbiso chepamusoro, haizobudisi zvinhu zvinokuvadza kunyange pasi pemamiriro ezvinhu akaipisisa akadai sekushisa kwepamusoro uye kudzvinyirira, saka ine kuchengetedzwa kwepamusoro.
Chechipiri, iyo nzvimbo yekushandiswa kwemitsara yePTFE mavharuvhu
1. Chemical industry: PTFE lined valves inoshandiswa zvakanyanya muindasitiri yemakemikari, kunyanya mumagetsi anoodza, ane acid yakasimba uye alkali environments, PTFE lined valves inogona kuvimbisa kushanda kwakachengeteka kwemichina uye kuderedza mari yekugadzirisa.
2. Petroleum industry: Muindasitiri yepetroleum, PTFE mavharuvhu ane mutsara anowanzo shandiswa kutakura mafuta, gasi rechisikigo uye mamwe midhiya, uye ayo akanakisa kushora uye kuvharika kwekuita kunoita kuti PTFE yakarongedzerwa mavharuvhu ave anofarira vharafu muindasitiri yepetroleum.
3. Indasitiri yemishonga: Indasitiri yemishonga ine zvinodiwa zvakanyanya zvehutsanana nekuchengeteka kwemidziyo, uye tetrafluorolined valve inongosangana nezvinodiwa izvi, saka inoshandiswa zvakanyanya mumhizha yemishonga.
4. Indasitiri yemagetsi: Kushandiswa kwePTFE yakavharidzirwa mavharuvhu muindasitiri yemagetsi inonyanya kuratidzwa mukufambisa uye kutonga kwepamusoro-kuchena magasi uye zvinwiwa, uye kushanda kwayo kwakanakisa kunogona kuve nechokwadi chekushanda kwakagadzikana kwemidziyo yemagetsi.
6. Indasitiri yezvokudya: Pamusana pezvakanaka zve-anti-viscosity uye anti-corrosion properties zvePTFE lined valves, zvakashandiswawo zvakanyanya mumhizha yezvokudya, zvakadai sekushanda kwakanakisisa mukufambisa midhiya yepamusoro-soro yakadai sesirasi nejusi.
Muchidimbu, mavharuvhu ane mutsara ePTFE akashandiswa zvakanyanya muminda yakawanda nekuda kwekunakisisa kwavo kuita kwakanakira. Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, nzvimbo yekushandiswa yePTFE mavharuvhu ane mitsetse ichawedzerwa zvakare mune ramangwana.
