Khetho ea thepa ea tiiso bakeng sa valve ea bolo ke ea bohlokoa bakeng sa ts'ebetso ea eona e atlehileng.Ka poso ena, re tla sheba tse ling tsa litšobotsi tse kholo tsa likhetho tse tšeletseng tse sebelisoang hangata bakeng sa litiiso tsa polymer ka li-valve tsa bolo.
Mona ke tse ling tsa poso ho Litulo tsa Polymer le Tharollo ea ho Tiisa:
- Litulo tsa Li-valve tsa Ball - Likhetho tse 9 tsa bohlokoa tsa ho reka
- Tataiso ea Tharollo ea Tharollo ea Tiiso ea Ts'ebetso e Phahameng ea EMC Technologies
- Litiiso tsa PTFE Rotary Lip - Bahlolisani ba 6 ha ba Batla Hore U Tsebe!
Lintlha tsa bohlokoa #1:Moroetsana PTFE
Virgin PTFE (polymer lebitso la khoebo) e loketse joalo ka thepa ea tiiso ea valve bakeng sa likhatello tse ka tlase ho 5 ksi le mocheso pakeng tsa -20 F le 400 F;leha ho le joalo, ts'ebetso ea eona ea mocheso e itšetlehile ka khatello.Ha re bua ka khatello, PTFE ha e fokotsehe hantle ka mor'a ho hatelloa.Hlokomela hore polymer ha e sebetse hantle ha e le tlas'a liphetoho tsa mocheso ho feta 167 F. E 'ngoe ea matla a eona a maholo ke ho hanyetsa lik'hemik'hale, ho ba haufi le ho se qhibilihe;matla a mang ke khohlano e tlase haholo.E boetse e thibela mollo.
Lintlha tsa bohlokoa #2:Khalase e Matlafalitsoeng PTFE
PTFE e matlafalitsoeng joalo ka ha e sebelisoa ho li-valve tsa li-ball valve hangata ke 15% ea fiber ea khalase, e eketsang mocheso le tekanyo ea khatello e fumanehang ka moroetsana PTFE.Joalo ka polymer e sa matlafatsoang, khalase e matlafalitsoeng PTFE e ntse e na le khanyetso e ntle haholo ea lik'hemik'hale ntle le li-hot caustics le hydroflourics.Le eona, ha e na mollo ebile e na le likhohlano tse tlase, leha e se tlase joalo ka PTFE ea moroetsana.
Lintlha tsa bohlokoa #3:PTFE e Matlafalitsoe ka tšepe e sa hloekang
Ho na le mofuta o mong oa PTFE e matlafalitsoeng eo ka linako tse ling e sebelisoang litiisong tsa li-valve tsa bolo: tšepe e sa hloekang e matlafalitsoeng PTFE.Thepa ena e kopantsoeng ea tiiso e entsoe ka 50% polymer le 50% phofo ea 316 tšepe e sa hloekang.Mocheso oa eona oa mocheso ke -20 F ho ea ho 550 F (e phahame ho feta PTFE ea moroetsana) 'me e na le matla a phahameng a khatello ho feta moroetsana kapa khalase e matlafalitsoeng ke PTFE.Le eona, e hanela mollo, leha ho le joalo coefficient ea eona ea likhohlano e phahame ho feta PTFE.
Lintlha tsa bohlokoa #4:PEKE
PEEK ke khetho ha litlhoko li le ka ntle ho mocheso oa PTFE.PEEK e sebetsa hantle libakeng tse nang le mocheso o pakeng tsa -70 F ho isa ho 600 F, 'me ha e amehe ke ho pepesehela mouoane le metsi a chesang khafetsa.E matla ho feta polymer, empa hape e thata.Tšabo ea eona e ka sehloohong, ntle le ho tiea ha eona, ke boitšoaro ba eona bo hlephileng ha mocheso o le tlaase.
Lintlha tsa bohlokoa #5:UMHW Polyethylene
UHMW Polyethylene e bonahala e le khetho bakeng sa lisebelisoa tse khethehileng, ho kenyelletsa le moo ho tla ba le mahlaseli a tlaase ho isa ho a mahareng.Khatello ea eona ke 1.5 ksi 'me mocheso oa eona ke -70 F ho 200 F 1500 psi -57C ho 93C.UHMW Polyethylene e boetse e na le khanyetso e ntle haholo ea abrasion.
Lintlha tsa bohlokoa #6:Polyether ea chlorinated
Ka linako tse ling polyether ea chlorinated e sebelisoa e le lisebelisoa tsa tiiso ea ball valve, e sebetsang ka mocheso ho fihlela ho 257 F. E sebetsa hantle ka pel'a li-acids le solvents haeba ho nolofatsa ho ka mamelloa, 'me ho hanyetsana le lik'hemik'hale tse fetang 300.Ha e qhekelle, 'me ha e rate ho monya metsi.
Litiiso li Tsoela Pele ho Tsoela Pele:
Lisebelisoa tsa tiiso ke lebala le lulang le fetoha, empa lisebelisoa tsena tse tšeletseng li bonahala e le tsona tse etelletseng pele likhethong tsa li-valve tsa thermoplastic ball valve.Litšobotsi tsa bona tse kholo li bonahala ho ts'ebetso ea khatello le mocheso, likhohlano tse tlase, khanyetso ea lik'hemik'hale.
