"Khetho ea Li-valve tsa Amerika tse Sebetsang tsa Cast Steel Globe: Tataiso ea Litlhaloso, Likhatello tsa Khatello, le Lisebelisoa"

Valve ea lefatše ea tšepe e tloaelehileng ea Amerika ke valve e sebelisoang hangata indastering, e sebelisoang haholo masimong a kang peterole, lik'hemik'hale le kalafo ea metsi. Ho bohlokoa ho khetha valve e loketseng ea Amerika ea tšepe ea tšepe ea tšepe ho netefatsa ts'ebetso e bolokehileng ea lisebelisoa le ho ntlafatsa ts'ebetso ea tlhahiso. Sengoliloeng sena se tla hlahisa lintlha tsa bohlokoa tseo u lokelang ho li ela hloko ha u khetha li-valve tsa tšepe tse tloaelehileng tsa Amerika, ho kenyelletsa le litlhaloso, litekanyetso tsa khatello, le lisebelisoa, ho u thusa ho etsa liqeto tse bohlale.

1. Khetho ea likhetho

1. bophara ba lebitso: Bophara ba lebitso la li-valve tsa lefats'e tsa tšepe tse tloaelehileng tsa Amerika li lokela ho ts'oana le bophara ba sistimi ea liphaephe. Khetha lintlha tse nepahetseng tsa li-valve ho latela litlhoko tsa 'nete.
2. khatello ea lebitso: khatello ea lebitso e bolela khatello e phahameng eo valve e ka e mamellang tlas'a maemo a tloaelehileng a ho sebetsa. Ha u khetha li-valve tsa globe tsa tšepe tse tloaelehileng tsa Amerika, ho lokela ho netefatsoa hore khatello ea lebitso la valve e kholo ho feta kapa e lekana le khatello e phahameng ea ho sebetsa ea tsamaiso ea liphaephe.
3. Mokhoa oa khokahanyo: Mekhoa ea ho hokahanya bakeng sa li-valve tsa lefatše tsa tšepe tse tloaelehileng tsa Amerika li kenyelletsa khokahanyo ea khoele, khokahanyo ea flange, joalo-joalo Khetha mokhoa o nepahetseng oa ho hokahanya ho latela litlhoko tsa sebele.

2、 Khetho ea boemo ba khatello

Tekanyo ea khatello ea li-valve tsa globe ea tšepe ea Amerika e tloaelehileng hangata e arotsoe ka mekhahlelo e mene: khatello e tlase, khatello e mahareng, khatello e phahameng le khatello e phahameng haholo. Ha u khetha, boemo bo loketseng ba khatello bo lokela ho khethoa ho latela maemo a sebele a ho sebetsa.

1. Tekanyetso e tlase ea khatello: e loketse maemo ao khatello e mahareng e leng tlase kapa e lekanang le 1.6MPa.
2. Tekanyo ea khatello e mahareng: e loketse maemo ao khatello e mahareng e leng kholo ho feta 1.6 MPa le ka tlase ho kapa ho lekana le 10.0 MPa.
3. Boemo ba khatello e phahameng: bo loketse maemo ao khatello e mahareng e leng kholo ho feta 10.0MPa le ka tlase ho kapa ho lekana le 42.0MPa.
4. Boemo ba khatello e phahameng haholo: bo loketse maemo ao khatello e mahareng e leng kholo ho feta 42.0MPa.

3. Khetho ea lintho tse bonahalang

Lisebelisoa tsa li-valve tsa lefats'e tsa tšepe tse tloaelehileng tsa Amerika li na le tšusumetso e kholo ho hanyetseng ha tsona ho kutu, ho hanyetsa mocheso le matla. Khetha lisebelisoa tse nepahetseng tsa li-valve, tse kang tšepe ea carbon, tšepe e sa hloekang, alloy, joalo-joalo, ho itšetlehile ka thepa ea mochine o tsamaisang thepa.

1. Lisebelisoa tsa tšepe ea carbon: tse loketseng maemo a kakaretso a ho sebetsa moo sehare e leng metsi, mouoane, oli, joalo-joalo.
2. Lisebelisoa tsa tšepe tse sa hloekang: tse loketseng maemo a ho sebetsa ka lino tse senyang, likhase, joalo-joalo, 'me li na le khanyetso e ntle ea kutu.
3. Lisebelisoa tsa alloy: tse loketseng maemo a khethehileng a ho sebetsa joalo ka mocheso o phahameng, khatello e phahameng le ho senya, ka matla a phahameng le ho hanyetsa kutu.

Kakaretso:

Ho khetha valve e loketseng ea Amerika ea tšepe ea tšepe ea tšepe e hlokang ho nahanoa ka botlalo ka likarolo tsa bohlokoa joalo ka litlhaloso, maemo a khatello le lisebelisoa. Boenjiniere bo sebetsang, litlhaloso tsa li-valve, maemo a khatello, le lisebelisoa li khethoa ka mokhoa o utloahalang ho latela litlhoko le litšoaneleho tse mahareng tsa liphaephe ho netefatsa ts'ebetso e bolokehileng, e tsitsitseng le e sebetsang ea li-valve. Haeba ho na le litlhoko tse khethehileng, li-valve tsa Amerika tse entsoeng ka tšepe tse entsoeng ka tšepe tse nang le mehaho e khethehileng li ka etsoa ho finyella litlhoko tsa maemo a khethehileng a ho sebetsa.
