PTFE e na le khanyetso e phahameng ka ho fetesisa ea lik'hemik'hale 'me e ka hanela kutu ho tsoa ho lintho tse ngata tsa asiti le alkali, kahoo setulo sa PTFE le PTFE lined disc li loketse liphaephe tse nang le mecha ea litaba e senyang.
Serurubele sa PTFE se boetse se na le mocheso o babatsehang le ho hanyetsa serame 'me se ka boloka ts'ebetso e tsitsitseng tlas'a mocheso o feteletseng.
Lisebelisoa tsa PTFE li na le coefficient e tlase haholo ea likhohlano, e thusang ho fokotsa torque ea ts'ebetso le ho etsa hore ts'ebetso ea li-valve tsa serurubele e be bonolo ebile e be bonolo.
Phapang lipakeng tsa PTFE Seat of PTFE Liner:
Setulo sa valve sa PTFE se phuthetsoe holim'a mokokotlo oa rabara e thata 'me ka ho toba se thehoa sebopeho sa setulo sa valve.
E kentsoe 'meleng oa valve ho fana ka ts'ebetso ea ho tiisa.
PTFE lining ke lera la PTFE le sebelisoang ka hare ho 'mele oa valve, ho kenyelletsa le lifahleho tse qetellang moo li hokahaneng le phala.
Li-valve tsa PTFE-lined Disc le PTFE setulo sa serurubele li sebelisoa haholo lik'hemik'hale, meriana, tlhahiso ea matla le liindasteri tse ling. Li-valve tsena li etselitsoe ka ho khetheha ho laola ho phalla ha maro a senyang.
Lesela la PTFE ka hare ho valve le fana ka kutu e babatsehang le ho hanyetsa mocheso o phahameng, ho etsa hore e be e loketseng bakeng sa mefuta e sa tšoaneng ea liindasteri. Moralo oa setaele oa li-valve tsena tsa serurubele o etsa hore li be bobebe 'me ho be bonolo ho li kenya lipakeng tsa li-flange.
Li-valve tsa serurubele sa setulo sa PTFE li tsebahala ka ho tšoarella ha tsona le litlhoko tse tlase tsa tlhokomelo. Moralo oa disc oa valve o fokotsa moferefere 'me o nolofalletsa litekanyetso tse phahameng tsa phallo, e leng se etsang hore e be tharollo e theko e boima bakeng sa lits'ebetso tsa indasteri. Moralo o kopaneng oa li-valve tsena o thusa ho kenngoa libakeng tsa indasteri mme o boloka sebaka sa bohlokoa.
