Na Li-valve tsa Ball li ka Sebelisoa Bakeng sa Mouoane​: Tataiso ea Khetho ea Li-valve tsa Pipeline

Tataiso ea Khetho ea Valve ea Liphaephe tsa Mouoane: Litlhoko tsa Valve ea Libolo le Mefuta e Tloaelehileng

Mekhoa ea mouoane ea indasteri e hloka khetho e nepahetseng ea li-valve bakeng sa polokeho le katleho.Li-valve tsa boloSebetsa ka har'a liphaephe tsa mouoane feela ha u fihlela maemo a thata: khanyetso ea mocheso o phahameng/khatello, ho tiisa ka matla, le meralo e ikhethileng ea mouoane (mohlala, li-valve tsa bolo tse koetsoeng ka thata tse nang le sekoti se felletseng). Tlhaloso ea tekheniki ke ena:

1. Litlhoko tsa Bohlokoa bakeng sa Li-valve tsa Libolo tsa Mouoane

◼ Maemo a Thepa le Meaho

• Lisebelisoa tsa Mocheso o Phahameng: Mebele ea li-valve e hloka tšepe ea ASTM A216 WCB kapa e lekanang le eona.
• Moralo oa Boro bo Felletseng: E ​​netefatsa phallo e sa thibeloang; sehlopha sa khatello se tlameha ho lumellana le liphaephe (mohlala, Sehlopha sa 150 = 2.0MPa).

◼ Tshebetso ea ho Tiisa

• Litiiso tse Thata Feela: Litiiso tse bonolo lia hloleha tlas'a mocheso oa mouoane (>150°C).
• Ho Potoloha ho Tsitsitseng: Meralo ea bolo e phaphametseng/e tsitsitseng e tlameha ho fokotsa ho tsofala.

◼ Mekhoa e Metle ea Ts'ebetso

• Ho Kenya Dikutu Tse Otlolohileng: E ​​nolofalletsa ho chencha ka potlako ka 90° le thibelo ya ho dutla.

◼ Litlhokomelo tsa Bohlokoa

• Ditshebediso: E loketse bakeng sa ho tima/ho lokisa ka potlako mouoane dibakeng tsa oli, dikhemikhale le tsa motlakase.
• Meeli ea Phallo: Lebelo >40m/s le baka khoholeho ea mobu – khetha mehlala e ipapisitseng le sekhahla sa phallo ea liphaephe.
• Tlhokomelo: Hlahloba litiiso kotara le kotara, tlosa li-depositi tsa kahare, 'me u latele litataiso tsa OEM.

2. Li-valve tse 3 tse holimo tsa mouoane li bapisoa

3. Litlhoko tsa Universal Steam Valve

Li-valve tsohle tsa mouoane li lokela ho ba le:

1. Khanyetso ea Mocheso o Phahameng: Ts'ebetso e tsoelang pele ea >150°C.
2. Tšireletso ea ho senyeha: Sebelisa tšepe e sa ruseng ea 316L bakeng sa mouoane o senyang.
3. Litiiso tsa ho se dutle matla: Thibela tahlehelo ea matla le likotsi tsa polokeho.

4. Melao ea ho Latela Melao le Khetho

• Likhoutu tsa Machaba: Latela API 600, ASME B16.34, DIN/EN bakeng sa moralo/teko.
• Mekhoa ea Khetho: Kopanya lintlha tsa valve le khatello ea phaephe, mocheso, sekhahla sa phallo le mecha ea phatlalatso.
• Ho kenya: Khomarela ANSI B31.1 bakeng sa polokeho ea sistimi ea mouoane.

Kakaretso:

Li-valve tsa bolo tse nang le globe, heke, le tse lumellanang le melao ke likhetho tsa mantlha bakeng sa liphaephe tsa mouoane. Beha pele li-valve tsa bolo tse koetsoeng ka thata tse nang le 'mele ea ASTM WCB, netefatsa sekhahla sa phallo (<40m/s), 'me u kenye tšebetsong tlhokomelo e tloaelehileng.
