Selelekela sa thepa ea valve ea bolo

Lisebelisoa tsa valve ea bolo lia fapana ho ikamahanya le maemo a fapaneng a mosebetsi le litlhoko tsa mecha ea phatlalatso. Tse latelang ke tse ling tsa lisebelisoa tse tloaelehileng tsa valve ea bolo le litšobotsi tsa tsona:

1. Thepa ea tšepe e entsoeng ka tšepe

Tšepe e putsoa: e loketse metsi, mouoane, moea, khase, oli le lintho tse ling tse nang le khatello e tloaelehileng ea PN≤1.0MPa le mocheso -10℃ ~ 200℃. Mefuta e sebelisoang hangata ke HT200, HT250, HT300, HT350.

Tšepe e tenyetsehang: e loketse metsi, mouoane, moea le oli e nang le khatello e tloaelehileng PN≤2.5MPa le mocheso -30℃ ~ 300℃. Mefuta e sebelisoang hangata ke KTH300-06, KTH330-08, KTH350-10.

Tšepe e qhibilihisitsoeng: E ​​loketse PN≤4.0MPa, mocheso -30℃ ~ 350℃ metsi, mouoane, moea le oli le lintho tse ling tse sebelisoang khafetsa. Mefuta e sebelisoang hangata ke QT400-15, QT450-10, QT500-7. Ho phaella moo, tšepe e qhibilihisitsoeng e nang le silicon e phahameng e hanelang asiti e loketse lintho tse senyang tse nang le khatello e tloaelehileng ea PN≤0.25MPa le mocheso o ka tlase ho 120℃.

2. Tšepe e sa ruseng

Valve ea bolo ea tšepe e sa ruseng e sebelisoa haholo liphaepheng tsa khatello e mahareng le e phahameng, e nang le khanyetso e matla ea mocheso, 'me e sebelisoa haholo indastering ea lik'hemik'hale, petrochemical, ho qhibilihisa le liindasteri tse ling. Thepa ea tšepe e sa ruseng e na le khanyetso e ntle ea k'holeseterole le matla a mocheso o phahameng, e loketse mefuta e fapaneng ea mecha ea phatlalatso e senyang le tikoloho ea mocheso o phahameng.

3. Thepa ea koporo

Motsoako oa koporo: E loketse metsi a PN≤2.5MPa, metsi a leoatle, oksijene, moea, oli le lintho tse ling tse sebelisoang, hammoho le mocheso oa -40℃ ~ 250℃ mouoane oa mouoane. Mefuta e sebelisoang hangata ke ZGnSn10Zn2 (boronse ea tin), H62, Hpb59-1 (boronse), QAZ19-2, QA19-4 (boronse ea aluminium) jj.

Koporo e nang le mocheso o phahameng: e loketse mouoane le lihlahisoa tsa peterole tse nang le khatello e tloaelehileng ea PN≤17.0MPa le mocheso oa ≤570℃. Mefuta e sebelisoang hangata ke ZGCr5Mo, 1Cr5Mo, ZG20CrMoV jj.

4. Tšepe ea khabone

Tšepe ea khabone e loketse metsi, mouoane, moea, haeterojene, ammonia, naetrojene le lihlahisoa tsa peterole tse nang le khatello e tloaelehileng ea PN≤32.0MPa le mocheso -30℃ ~ 425℃. Mekhahlelo e sebelisoang hangata ke WC1, WCB, ZG25 le tšepe ea boleng bo holimo ea 20, 25, 30 le tšepe ea sebopeho e nang le motsoako o tlase oa 16Mn.

5. Thepa ea polasetiki

Valve ea bolo ea polasetiki e entsoe ka polasetiki bakeng sa thepa e tala, e loketseng ho thibela ts'ebetso ea ho fetisa ka mecha ea phatlalatso e senyang. Liplastiki tse sebetsang hantle joalo ka PPS le PEEK li sebelisoa hangata e le litulo tsa valve ea bolo ho netefatsa hore sistimi ha e senyehe ke lik'hemik'hale tse teng ha nako e ntse e ea.

6. Thepa ea letsopa

Valve ea bolo ea letsopa ke mofuta o mocha oa thepa ea valve, e nang le khanyetso e ntle ea ho bola le khanyetso ea ho tsofala. Botenya ba khetla ea valve bo feta litlhoko tsa maemo a naha, 'me likarolo tsa lik'hemik'hale le thepa ea mechini ea thepa ea mantlha li fihlela litlhoko tsa maemo a naha. Hona joale, e sebelisoa tlhahisong ea motlakase ea mocheso, tšepe, peterole, ho etsa pampiri, boenjiniere ba baeloji le liindasteri tse ling.

7. Lisebelisoa tse khethehileng

Tšepe e mocheso o tlase: e loketse khatello e tloaelehileng PN≤6.4MPa, mocheso oa ≥-196℃ ethylene, propylene, khase ea tlhaho e metsi, naetrojene e metsi le lintho tse ling tse sebelisoang khafetsa. Mefuta e sebelisoang hangata ke ZG1Cr18Ni9, 0Cr18Ni9, 1Cr18Ni9Ti, ZG0Cr18Ni9 jj.

Tšepe e sa hloekang e hanelang asiti: e loketse asiti ea nitric, asiti ea acetic le lintho tse ling tse nang le khatello ea PN≤6.4MPa le mocheso oa ≤200℃. Mefuta e tloaelehileng ke ZG0Cr18Ni9Ti, ZG0Cr18Ni10 (ho hanyetsa asiti ea nitric), ZG0Cr18Ni12Mo2Ti, ZG1Cr18Ni12Mo2Ti (ho hanyetsa asiti le urea) jj.

Ka bokhutšoanyane, khetho ea thepa ea valve ea bolo e lokela ho khethoa ho latela maemo a itseng a mosebetsi le litlhoko tse mahareng ho netefatsa ts'ebetso e tloaelehileng le botsitso ba nako e telele ba valve.
