Ivalvu yebhabhathane engagqwali enophahla lwe-fluoroplasticukubeka i-polytetrafluoroethylene resin (noma iphrofayili ecutshunguliwe) odongeni lwangaphakathi lwezingxenye eziphethe umfutho we-valve ye-butterfly yensimbi noma yensimbi noma ubuso bangaphandle bezingxenye zangaphakathi ze-valve ye-butterfly ngendlela yokubumba (noma yokufaka). Izakhiwo ezihlukile zama-valve e-butterfly ngokumelene nemidiya eqinile ebolayo zenziwa izinhlobo ezahlukene zama-valve e-butterfly kanye nemithambo yokucindezela.
Ezintweni ezilwa nokugqwala, i-PTFE inokusebenza okuhle kakhulu okungenakuqhathaniswa. Ngaphezu kwensimbi encibilikisiwe, i-fluorine eyisisekelo kanye nama-hydrocarbon aromatic, ingasetshenziswa ekugxilweni okuhlukahlukene kwe-hydrochloric acid, i-sulfuric acid, i-nitric acid, i-aqua regia, i-organic acid, i-oxidant enamandla, i-concentrated, i-alternating dilute acid, i-alkali eshintshanayo kanye nezinto eziphilayo ezahlukahlukene kuyimiphumela engahleliwe. Ukufakwa kwe-PTFE odongeni lwangaphakathi lwe-butterfly valve akugcini nje ngokunqoba ukushiyeka kwamandla aphansi ezinto ze-PTFE, kodwa futhi kuxazulula inkinga yokumelana nokugqwala kwezinto zetimu ye-butterfly valve. Ukusebenza okubi kanye nezindleko eziphakeme. Ngaphezu kwalokho, ngaphezu kokuqina kwayo okuhle kwamakhemikhali, i-PTFE inezakhiwo ezinhle zokuvimbela ukungcola kanye nokunamathela, ama-coefficients amancane kakhulu ashukumisayo kanye nama-static friction, kanye nokusebenza okuhle kokulwa nokugqwala. Isetshenziswa njenge-sealing pair yokuvula nokuvala ama-butterfly valve, futhi kuyadingeka ukunciphisa ubuso bokuvala. Ukungqubuzana phakathi kwama-butterfly valve kungancishiswa, i-torque yokusebenza ye-butterfly valve ingancishiswa, futhi impilo yenkonzo yomkhiqizo ingathuthukiswa.
Ivalvu yebhabhathane efakwe i-fluorine, eyaziwa nangokuthi i-valve ye-butterfly elwa nokugqwala, ivame ukusetshenziswa ezimweni zokusebenza ezinzima, kungaba ngamakhemikhali anobuthi futhi ayingozi, noma izinhlobo ezahlukene ze-acid-base noma izinyibilikisi eziphilayo ezigqwala kakhulu. Ukusetshenziswa okungalungile kuzoholela ekulahlekelweni okukhulu kwezomnotho kanye nomphumela ongathi sína. Ukusetshenziswa okufanele kanye nokugcinwa kwe-valve ye-butterfly kungandisa isikhathi senkonzo ye-valve ye-butterfly ene-fluorine, ngakho-ke yimiphi imininingwane engenziwa ukuze ivikelwe ngempumelelo?
1. Ngaphambi kokusebenzisa, funda ngokucophelela incwadi yemiyalelo yevalvu yebhabhathane ene-fluorine.
2. Yisebenzise ngaphakathi kwebanga lokucindezela, izinga lokushisa kanye nendawo echazwe ku-nameplate noma encwadini yemiyalelo.
3. Uma isetshenziswa, vimbela ivalvu yebhabhathane efakwe i-fluorine ukuthi ingadali ukucindezeleka okukhulu kwepayipi ngenxa yokushintsha kwezinga lokushisa, nciphisa izinguquko zokushisa, bese wengeza amalunga okunwebeka anomumo we-U ngaphambi nangemva kwevalvu yebhabhathane.
4. Akuvunyelwe ukusebenzisa i-lever ukuvula nokuvala i-valve ye-butterfly ene-fluorine. Qaphela ukuthi indawo yokubonisa ukuvulwa nokuvalwa kwayo kanye nedivayisi yomkhawulo we-valve ye-butterfly ene-fluorine. Ngemva kokuthi ukuvulwa nokuvalwa sekusendaweni, ungayiphoqi i-valve ukuthi ivale, ukuze ugweme ukulimala kusenesikhathi ebusweni bokuvala ipulasitiki ye-fluorine.
5. Kwezinye izithombo ezingazinzile futhi ezilula ukubola (isibonelo, ukubola kwezinye izithombo kuzobangela ukwanda kwevolumu futhi kubangele ukwanda kwengcindezi okungavamile ezimweni zokusebenza), okuzobangela umonakalo noma ukuvuza kwevalvu yebhathane, kufanele kuthathwe izinyathelo zokususa noma ukunciphisa izinto ezibangela ukubola kwezithombo ezingazinzile. . Lapho ukhetha ivalvu yebhathane, ivalvu yebhathane ene-fluorine enedivayisi yokukhulula ingcindezi ngokuzenzakalelayo kufanele ikhethwe ngokucabangela izinguquko ezingaba khona ezimweni zokusebenza ezibangelwa ukubola okungazinzile nokulula kwento yokuxhumana.
6. Ngobaivalvu yebhabhathane eline-fluorineepayipini elinobuthi, elivuthayo, eliqhumayo nelinamandla agqwalisayo, akuvunyelwe ngokuphelele ukufaka esikhundleni sokupakisha ngaphansi kwengcindezi. Nakuba ivalvu yebhabhathane ene-fluorine inomsebenzi wokuvala ophezulu ekwakhiweni, akukhuthazwa ukufaka esikhundleni sokupakisha ngaphansi kwengcindezi.
7. Kumapayipi ane-medium yokushisa ezenzakalelayo, kufanele kuthathwe izinyathelo zokuqinisekisa ukuthi izinga lokushisa elizungezile kanye nezinga lokushisa lesimo sokusebenza alikwazi ukudlula iphuzu lokushisa elizenzakalelayo le-medium ukuvimbela ingozi ebangelwa ukukhanya kwelanga noma umlilo wangaphandle.
Indawo esetshenziswayo: amazinga ahlukahlukene kasawoti we-acid-base kanye nezinye izinyibilikisi eziphilayo.
