Litaba

Li-valve tsa bolo ea turbine li sebelisoa haholo liindastering tse ngata, ho kenyelletsa lik'hemik'hale, peterole, khase ea tlhaho, metallurgy, papermaking le meriana. Tsa bona sebopeho se bonolo, ts'ebetso e babatsehang ea ho tiisa, bophelo bo bolelele ba tšebeletso, le boiketlo ba tlhokomelo li etse lisebelisoa tsa bohlokoa bakeng sa ho laola phallo ea mecha ea litaba tsamaisong ea lipeipi. E le karolo ea bohlokoa ea valve ea bolo ea turbine, ea ho tiisa ts'ebetso ea lebokose la gear e ama ka kotloloho ts'ebetso ea eona e nepahetseng le bophelo ba ts'ebeletso. Ka hona, ho ntlafatsa ts'ebetso ea ho tiisa ea lebokose la gear le ho atolosa nako ea eona ea tlhokomelo ho bohlokoa haholo.

Li-valve tsa bolo ea moea li ntse li sebelisoa haholo mekhoeng ea sejoale-joale ea taolo ea liindasteri, 'me ts'ebetso ea bona e potlakileng le e nepahetseng ea karabelo e bohlokoa bakeng sa ho netefatsa ts'ebetso e tsitsitseng ea sistimi.

Ka lebaka la tikoloho ea eona e ikhethang ea ts'ebetso, indasteri ea petrochemical e beha litlhoko tse phahameng haholo mabapi le polokeho ea lisebelisoa. E le karolo ea bohlokoa bakeng sa ho laola phallo ea mokelikeli libakeng tse ka bang teng ho phatloha, li-valve tsa bolo ea motlakase tse thibelang ho phatloha hloka Setifikeiti sa ATEX, tekanyetso ea bohlokoa ea tšireletso.

Libakeng tsa liindasteri tse nang le mocheso o phahameng, li-valve tsa bolo tse thata tse nang le mocheso o phahameng tse sebetsang ka holimo ho 800 ° C li bapala karolo ea bohlokoa. Ho netefatsa ts'epo ea bona le ts'ebetso ea tiiso tlas'a maemo a feteletseng, mekhoa e mecha ea matšeliso ea ho senyeha ha mocheso li bohlokoa ka ho khetheha.

Lefapheng la indasteri, li-valve tsa bolo tse nang le karolo e le 'ngoe, e tsejoang hape e le li-valve tsa bolo tse cheselitsoeng ka botlalo, li sebelisoa haholo tsamaisong ea lipeipi liindastering tse ngata, ho kenyeletsoa le petroleum, lik'hemik'hale, khase ea tlhaho, le ho futhumatsa, ka lebaka la ts'ebetso ea bona e babatsehang ea ho tiisa le ho hanyetsa khatello e phahameng le mocheso o phahameng.

Li-acids tse matla le alkalis li sebelisoa haholo mafapheng a mangata a indasteri, joalo ka lik'hemik'hale tsa petrole, metallurgy, le meriana. Mecha ea litaba e senyang e beha litlhoko tse phahameng haholo tsa lisebelisoa.

Li-valve tsa bolo tse thibelang kutu tse nang le fluorine, e le tharollo ea li-valve tsa setsebi, li fetohile khetho e tšepahalang bakeng sa lik'hamphani tse ngata ka lebaka la ho hanyetsa ha tsona ho hoholo.

Liindastering tse kang khemikhale le electroplating, li-valve tsa bolo ea li-anti-corrosion tse nang le fluorine li ratoa haholo bakeng sa khanyetso ea tsona e ntle ea kutu.

PTFEpolytetrafluoroethylene) lesela le phetha karolo ea bohlokoa ho ho lelefatsa bophelo ba tiiso ea li-valve tsa bolo.

Lilemong tsa morao tjena, naha ea heso maano a tshireletso ya tikoloho li se li le thata le ho feta, 'me tlhoko ea thepa e baballang tikoloho e ntse e eketseha ho pholletsa le liindasteri tse fapaneng. Ka indasteri ea li-valve, Li-valve tsa bolo ea polasetiki tsa PE, e le mofuta o mocha oa valve o bolokang tikoloho, butle-butle e hohetse tlhokomelo e atileng.

Mekhoeng ea sejoale-joale ea nosetso ea temo. Li-valve tsa bolo ea polasetiki tsa PE li ntse li ata ka ho eketsehileng ka lebaka la ho ikhetha ha tsona ho bobebe le lik'hemik'hale. Sengoliloeng sena se tla shebisisa melemo ea li-valve tsa bolo ea polasetiki tsa PE litsamaisong tsa nosetso tsa temo le hore na thepa ena e ka sebelisoa joang ho ntlafatsa ts'ebetso ea nosetso le chai ea lijalo.

Lefapheng la boenjiniere ba metsing, khetho ea li-valve ke ea bohlokoa, eo har'a eona li-valve tsa bolo ea tšepe tse 316 le li-valve tsa tšepe tse 304 ke khetho e tloaelehileng. Leha ho le joalo, ho bola ha li-valve tsena tsa tšepe tse sa hloekang ka bongata ba li-ion tsa chloride tikolohong ea leoatle ke bothata bo tebileng, bo tla ama ts'ebetso le bophelo ba ts'ebeletso ea li-valve, esita le ho sokela ts'ebetso e bolokehileng le e tsitsitseng ea sistimi eohle ea boenjiniere ba metsing. Ha re tšohleng ka ho qaqileng boemo ba li-valve tsena tse peli tsa tšepe tse sa hloekang tikolohong ea leoatle le tharollo ea ho thibela kutu ea chloride ion.
