Moralo le Maemo a Ts'ebetso a Li-Valves tsa Amerika tsa Cast Cast Steel Globe

Moralo le Maemo a Ts'ebetso a Li-Valves tsa Amerika tsa Cast Cast Steel Globe

Litsamaisong tsa lipeipi tsa indasteri, li-valve tsa lefats'e tsa tšepe tse tloaelehileng tsa Amerika li tsebahala haholo ka ho tšoarella ha tsona le ho ts'epahala ha tsona. Belofo ena e entsoe le ho etsoa ka tieo ho latela litlhaloso tse thehiloeng ke American National Standards Institute (ANSI) le American Petroleum Institute (API). Lintlha tse latelang li tla fana ka tlhahlobo e qaqileng ea litšobotsi tsa moralo oa li-valve tsa globe tsa tšepe tse tloaelehileng tsa Amerika le litekanyetso tsa ts'ebetso tseo li li latelang.

Likarolo tsa moralo

1. Khetho ea lintho tse bonahalang: Li-valve tsa globe tsa tšepe tse tloaelehileng tsa Amerika hangata li sebelisoa ka tšepe e boletsoeng ea ASTM, joalo ka ASTM A126 grade WCB (carbon steel castings), ho netefatsa hore valve e na le matla a matle a mochini le ho hanyetsa kutu.
2. Moralo oa ho tiisa: Setulo sa li-valve le disc li entsoe ka libaka tse tiisitsoeng tsa conical kapa selikalikoe tse ts'oanang hantle ho netefatsa thibelo e sebetsang ea ho lutla ha mahareng sebakeng se koetsoeng le ho fihlela phello e koalang e tiileng.
3. Moralo oa li-valve stem anti blowout: Ho thibela kutu ea valve hore e se ke ea fepeloa ke bohareng nakong ea ts'ebetso ea khatello e phahameng, valve ea Amerika e entsoeng ka tšepe e entsoe ka sesebelisoa sa anti blowout, se ntlafatsang polokeho ea valve.
4. Moqapi oa tšireletso ea mollo: Ho ea ka tekanyo ea tšireletso ea mollo ea API 607, li-valve tse ling tsa Amerika tse tloaelehileng tse entsoeng ka tšepe ea tšepe li entsoe ka mehaho e thibelang mollo, e ka bolokang bokhoni bo itseng ba ho tiisa esita le ha ho chesa, ho netefatsa polokeho ea tsamaiso.
5. Setiiso sa Valve stem: Ho sebelisoa karolo e ka nkeloang sebaka sa valve stem seal, e netefatsang khohlano e tlase nakong ea ho bula le ho koala, hape ho bonolo ho e hlokomela le ho e nkela sebaka.
6. Ts'ebetso ea wheelchair: Bakeng sa boiketlo ba ts'ebetso ea letsoho, li-valve tsa lefats'e tsa tšepe tse tloaelehileng tsa Amerika hangata li na le lebili la letsoho, 'me boholo le moralo oa matla oa lebili la letsoho li fihlela litlhoko tsa ANSI bakeng sa tšebeliso e bonolo ke opareitara.

Litekanyetso tsa ts'ebetso

1. Khatello ea Khatello: Li-valve tsa globe tsa tšepe tse tloaelehileng tsa Amerika li arotsoe ho ea ka litekanyetso tse loketseng tse kang ANSI / ASME B16.34, joalo ka Sehlopha sa 150 le Sehlopha sa 300, ho netefatsa ts'ebetso e sireletsehileng tlas'a likhatello tse fapaneng.
2. Mocheso oa mocheso: Ho ea ka mocheso oa mocheso oa thepa ea ASTM, li-valve tsa Amerika tse tloaelehileng tsa tšepe tse entsoeng ka tšepe li loketse maemo a fapaneng a ho sebetsa ho tloha tlaase ho ea ho mocheso o phahameng.
3. Boemo ba ho lutla: Ho latela maemo a ho lutla a FCI-70-2 (Factory Mutual Research), li-valve tsa lefatše tsa tšepe tse tloaelehileng tsa Amerika li fana ka maemo a fapaneng a ts'ebetso ea ho tiisa ho fihlela litlhoko tse fapaneng tsa kopo ea indasteri.
4. Khanyetso ea kutu ea lintho tse bonahalang: Sebopeho sa lik'hemik'hale le mokhoa oa ho phekola mocheso oa thepa o lumellana le melao ea ASTM, ho etsa bonnete ba hore valve e ntse e ka boloka khanyetso e ntle ea kutu mecheng ea litaba e senyang.
5. Setifikeiti sa Sehlahisoa: Li-valve tsa Amerika tse tloaelehileng tsa tšepe tsa tšepe hangata li hloka letoto la litifikeiti tsa sehlahisoa, ho kenyeletsoa tlhahlobo ea khatello, tlhahlobo ea ts'ebetso le tlhahlobo ea ho hanyetsa mollo, ho netefatsa hore li fihlela litlhoko tsa litekanyetso tse amehang.

Ka kakaretso, li-valve tsa tšepe tsa tšepe tse tloaelehileng tsa Amerika li shebana le ts'ebetso le polokeho moralong oa tsona, 'me li entsoe ka thata ho latela maemo a naha ea Amerika le litloaelo tsa indasteri ho netefatsa ts'ebetso e tsitsitseng tlasa maemo a thata a ho sebetsa. Ebang ke masimong a petroleum, lik'hemik'hale, khase ea tlhaho, kapa liindasteri tse ling, li-valve tsa lefatše tsa tšepe tse tloaelehileng tsa Amerika li bonts'itse ts'ebetso ea tsona e phahameng le ts'epo e phahameng. Ha u khetha li-valve tse joalo, basebelisi ba lokela ho hlahloba ka hloko litekanyetso tseo ba li finyellang le litlhoko tsa sebele tsa tikoloho ea ho sebetsa ho netefatsa ho nepahala ha khetho le ts'ebetso e sireletsehileng le e tsitsitseng ea tsamaiso.
