Ivalve uvemvane evikela ukugqwala ene-fluoroplasticukubeka i-polytetrafluoroethylene resin (noma iphrofayili ecutshunguliwe) odongeni lwangaphakathi lwensimbi noma izingxenye ezithwele uvemvane lwensimbi noma indawo engaphandle yezingxenye zangaphakathi zevalve uvemvane ngendlela yokubumba (noma inlay). Izici eziyingqayizivele zamavalvu ovemvane ngokumelene nemithombo yezindaba ezonakalisayo zenziwe zibe izinhlobo ezihlukahlukene zamavalve ovemvane nemikhumbi yokucindezela.
Ezintweni zokulwa nokugqwala, i-PTFE inokusebenza okuhle kakhulu okungenakuqhathaniswa. Ngaphezu kwensimbi encibilikisiwe, i-fluorine eyisisekelo kanye nama-hydrocarbons anephunga elimnandi, ingasetshenziswa ekugxilweni okuhlukahlukene kwe-hydrochloric acid, i-sulfuric acid, i-nitric acid, i-aqua regia, i-organic acid, i-oxidant eqinile, igxiliwe, i-alternating dilute acid, i-alkali eshintshanayo kanye nama-organic agents ahlukahlukene. ukusabela okungahleliwe. Ukufakwa kwe-PTFE odongeni lwangaphakathi lwe-valve uvemvane akunqobi kuphela ukushiyeka kwamandla aphansi wempahla ye-PTFE, kodwa futhi kuxazulula inkinga yokumelana nokugqwala kwezinto zetimu ye-butterfly valve. Ukusebenza kabi kanye nezindleko eziphezulu. Ukwengeza, ngaphezu kokuzinza kwayo okuhle kakhulu kwamakhemikhali, i-PTFE inezinto ezinhle zokunqanda ukubola kanye nezokulwa nenduku, ama-coefficients ashukumisayo amancane kakhulu namile, kanye nokusebenza okuhle kokulwa nokungqubuzana nokusebenza kokugcoba. Isetshenziswa njengepheya yokuvala yokuvula nokuvala ama-valve evemvane, futhi kuyadingeka ukunciphisa indawo yokuvala. Ukungqubuzana phakathi kwama-butterfly valve kungancishiswa, i-torque yokusebenza ye-butterfly valve ingancishiswa, futhi impilo yesevisi yomkhiqizo ingathuthukiswa.
I-valve yevemvane ene-fluorine, eyaziwa nangokuthi i-anti-corrosion butterfly valve, ivamise ukusetshenziswa ezimeni zokusebenza ezinzima, kungaba amakhemikhali anobuthi nayingozi, noma izinhlobo ezihlukahlukene ezigqwala kakhulu ze-acid-base noma izincibilikisi eziphilayo. Ukusetshenziswa okungalungile kuzoholela ekulahlekelweni okukhulu kwezomnotho futhi kubi kakhulu ngenxa yalokho. Ukusetshenziswa okulungile nokugcinwa kwe-valve ye-butterfly kungandisa impilo yesevisi ye-butterfly valve ene-fluorine, ngakho-ke yimiphi imininingwane engenziwa ukuze ivikeleke ngempumelelo?
1. Ngaphambi kokusebenzisa, funda ngokucophelela incwadi yeziqondiso zevalve uvemvane ene-fluorine.
2. Yisebenzise phakathi kwebanga lokucindezela, izinga lokushisa kanye nendawo eshiwo ku-nameplate noma kumanuwali.
3. Lapho isetshenziswa, vimbela i-valve yovemvane enomugqa we-fluorine ekukhiqizeni ukucindezeleka okukhulu kwepayipi ngenxa yokushintsha kwezinga lokushisa, unciphise ukushintsha kwezinga lokushisa, futhi wengeze amalunga okunwebeka amise okuka-U ngaphambi nangemuva kwevalve yovemvane.
4. Akuvunyelwe ukusebenzisa i-lever ukuvula nokuvala i-valve butterfly ene-fluorine. Naka ukubuka indawo yenkomba yokuvula nokuvala futhi ukhawule idivayisi yevalve uvemvane ene-fluorine. Ngemuva kokuthi ukuvulwa nokuvala sekukhona, ungaphoqi i-valve ukuvala, ukugwema ukulimala ngaphambi kwesikhathi endaweni yokuvala ipulasitiki ye-fluorine.
5. Kweminye imithombo yezindaba engazinzile futhi kulula ukubola (isibonelo, ukubola kwemidiya ethile kuzodala ukwanda kwevolumu futhi kubangele ukwanda kwengcindezi engavamile ezimweni zokusebenza), okuzobangela ukulimala noma ukuvuza kwe-butterfly valve, izinyathelo kufanele zithathwe ukuze kuqedwe. noma unciphise izici ezibangela ukubola kwemidiya engazinzile. . Lapho ukhetha i-valve ye-butterfly, i-valve ye-butterfly ene-fluorine ene-othomathikhi yokusiza ukucindezela idivayisi kufanele ikhethwe ngokucabangela izinguquko ezingenzeka ezimweni zokusebenza ezibangelwa ukubola okungazinzile nokulula kwe-medium.
6. Ngobai-valve yevemvane ene-fluorineepayipini elinendawo enobuthi, evuthayo, eqhumayo futhi eqinile edlayo, kwenqatshelwe ngokuphelele ukufaka indawo yokupakisha ngaphansi kwengcindezi. Nakuba i-valve ye-butterfly ene-fluorine inomsebenzi wokuvala ophezulu ekwakhiweni, akunconywa ukuthi kufakwe esikhundleni sokupakisha ngaphansi kwengcindezi.
7. Ngamapayipi anendawo evuthayo ezenzakalelayo, kufanele kuthathwe izinyathelo zokuqinisekisa ukuthi izinga lokushisa elisendaweni nesimo sokusebenza akukwazi ukudlula indawo ezenzakalelayo yokuvutha kwendawo ukuze kuvinjelwe ingozi ebangelwa ukukhanya kwelanga noma umlilo wangaphandle.
Isisetshenziswa esisebenzayo: ukugxila okuhlukahlukene kosawoti base-asidi nezinye izinyibilikisi eziphilayo.
