PTFE ulusi seal tepi

Tepi yosindikizira ulusi wa Plumber, filimu ya polytetrafluoroethylene, ili ndi mayina angapo omwe amagwiritsidwa ntchito nthawi zambiri monga PTFE tepi ndi tepi dope.Tepi ya PTFE imapereka chosindikizira chofunikira komanso kudzoza kwa ulusi wa chitoliro ndipo ndi njira ina yosinthira chitoliro chosokoneza nthawi zina.Tepi ya PTFE imabwera mumitundu yosiyanasiyana, yomwe nthawi zambiri imakhala yoyera, yachikasu ndi yobiriwira kuti igwirizane ndi mapaipi amtundu wa US ndi Canada.Tepi yoyera ndiyoyenera ntchito zoyambira zopopera madzi pomwe mitundu ina wamba, monga tepi yachikasu imapereka kachulukidwe kawiri ndipo imagwiritsidwa ntchito popopera mpweya komanso tepi yobiriwira imapereka kachulukidwe katatu ka mapaipi a oxygen.

Tepi yosindikizira ulusi(yomwe imadziwikanso kuti PTFE tepi kapena plumber's tepi) ndi filimu ya polytetrafluoroethylene (PTFE) yomwe imagwiritsidwa ntchito pomata ulusi wamapaipi.Tepiyo imagulitsidwa yodulidwa kuti ikhale m'lifupi mwake ndikumangirira pa spool, zomwe zimapangitsa kuti zikhale zosavuta kupota ulusi wa chitoliro.Amadziwikanso ndi tepi ya polima yopangidwa ndi genericized;pamene ma polima ali ofanana ndi PTFE, Chemours (omwe ali ndi chizindikiro) amaona kuti kugwiritsa ntchito uku sikulakwa, makamaka chifukwa sapanganso polima mu mawonekedwe a tepi. ulusi kuti ugwire pamene umasulidwa.Tepiyo imagwiranso ntchito ngati chodzaza chopunduka ndi mafuta a ulusi, kuthandizira kusindikiza mgwirizano popanda kuumitsa kapena kupangitsa kuti zikhale zovuta kulimbitsa, ndipo m'malo mwake zimapangitsa kuti zikhale zosavuta kuzimitsa.

Nthawi zambiri tepiyo imakulungidwa mozungulira ulusi wa chitoliro katatu isanayambe kukulungidwa.Amagwiritsidwa ntchito kwambiri pazamalonda kuphatikiza makina oponderezedwa amadzi, makina otenthetsera apakati, ndi zida zopondereza mpweya.

Tepi ya ulusi ndiyoyenera kugwiritsidwa ntchito pa ulusi wokhotakhota, pomwe mphamvu yosindikizira imakhala ngati mphero.Zingwe zofananira sizingasindikize bwino kapena popanda tepi, chifukwa zimapangidwira kuti zisindikizidwe ndi gasket.

Tepi yosindikizira ulusi pafupifupi imayikidwa pamanja, ngakhale pali makina amodzi opangira zomangira.

Tepi ya PTFE imagwiritsidwanso ntchito potambasula kuboola thupi, kudzera munjira yomwe imadziwika kuti kujambula, chifukwa ndiyosavuta komanso yotetezeka kugwiritsa ntchito izi.Wovalayo amakulunga zigawo za tepi mozungulira pulagi, pang'onopang'ono akuwonjezera kukula kwake ndipo motero akuwonjezera pang'onopang'ono kukula (gauge) ya kuboola.
