Valve ea heke ea wedge ea haeteroliki DN400 PN25

1. Tlhaloso le Likarolo tsa Bohlokoa

Valve ea Heke ea Hydraulic Wedge ke valve e tsamaeang ka mola moo disc (heke) e bōpehileng joaloka wedge e phahamisoang kapa e theoloang ke actuator ea hydraulic ho laola phallo ea mokelikeli.

Likarolo tsa Bohlokoa bakeng sa boholo le sehlopha sena:

• Moralo o Felletseng oa Boro: Bophara ba kahare bo tsamaellana le phaephe (DN400), e leng se fellang ka ho theoha ha khatello e tlase haholo ha e butsoe ka botlalo le ho lumella ho kenngoa ha liphaephe.
• Phallo ea Litsela Tse Pedi: E loketse phallo ka lehlakoreng lefe kapa lefe.
• Sefate se Phahamisang: Sefate se phahama ha valve e buloa, e leng se fanang ka ponts'o e hlakileng ea boemo ba valve.
• Ho Tiisoa ha Tšepe ho ea ho Tšepe: Hangata ho sebelisoa masale a wedge le a setulo a thata (mohlala, ka Stellite) bakeng sa khoholeho le ho hanyetsa ho tsofala.
• Kaho e Matla: E etselitsoe ho sebetsana le likhatello le matla a phahameng, e leng se fellang ka 'mele o boima le o tšoarellang, hangata o entsoe ka tšepe e entsoeng ka tšepe kapa e entsoeng ka tšepe.

2. Likarolo tse ka Sehloohong

1. Mmele: Sebopeho se seholo se nang le kgatello, seo hangata se entsweng ka Tshepe ya Khabone (WCB) kapa Tshepe e sa Tshabeng (CF8M/316SS). Dipheletso tse nang le di-flanged (mohlala, PN25/ASME B16.5 Class 150) ke tse tlwaelehileng bakeng sa DN400.
2. Bonnete: E tlameletsoe 'meleng, e boloka kutu 'me e fana ka moeli oa khatello. Hangata bonnete e atolositsoeng e sebelisetsoa merero ea ho thibela ho ruruha.
3. Wedge (Heke): Karolo ea ho koala senotlolo. Bakeng sa PN25, Wedge e Fetohang e tloaelehile. E na le sehiloeng kapa mokoti o potolohileng potoloho ea eona o lumellang wedge ho kobeha hanyane, ho ntlafatsa ho koala le ho lefella liphetoho tse nyane ho lekane ha setulo ka lebaka la katoloso ea mocheso kapa khatello ea phaephe.
4. Kutu: Shaft e nang le khoele e matla haholo (mohlala, SS420 kapa 17-4PH Stainless Steel) e fetisang matla ho tloha ho actuator ho ea ho wedge.
5. Masale a Setulo: Masale a sefahleho se thata a hatelletsoeng kapa a kopantsweng ka hare ho mmele oo wedge e koalang hodima wona. A etsa hore ho kwalehe ka thata.
6. Ho paka: Sekoahelo (hangata graphite bakeng sa mocheso o phahameng) ho potoloha kutu, e kentsweng ka lebokoseng la ho tlatsa, ho thibela ho dutla tikolohong.
7. Motlakase oa Hydraulic: Motlakase oa joko ea scotch o kang oa piston o tsamaisoang ke khatello ea hydraulic (hangata oli). E fana ka torque/thrust e phahameng e hlokahalang ho tsamaisa valve e kholo ea DN400 khahlanong le khatello e phahameng ea phapang.

3. Molao-motheo oa Mosebetsi

• Ho buleha: Mokelikeli oa hydraulic o kenngoa ka har'a actuator, o tsamaisa piston. Motsamao ona o fetoloa ho ba motsamao o potolohang (scotch joke) kapa o otlolohileng (piston e otlolohileng) o potolohang kutu ea valve. Thupa e kenella ka har'a wedge, e e phahamisa ka botlalo ka har'a bonnet, e sa sitise tsela ea phallo.
• Ho kwala: Mokelikeli oa haeteroliki o kentsoe ka lehlakoreng le leng la actuator, o khutlisetsa morao motsamao. Sekoti sea potoloha 'me se sutumelletsa wedge tlase boemong bo koetsoeng, moo se hatelloang ka thata khahlanong le masale a mabeli a setulo, e leng se etsang hore ho be le tiiso.

Tlhokomeliso ea Bohlokoa: Valve ena e etselitsoe ho itšehla thajana (e butsoe ka botlalo kapa e koetsoe ka botlalo). Ha ea lokela ho sebelisoa bakeng sa ho thiba kapa ho laola phallo, kaha sena se tla baka ho thothomela, ho thiba ha cavitation, le ho khoholeha ka potlako ha wedge le litulo.

4. Litšebeliso tse Tloaelehileng

Ka lebaka la boholo ba eona le tekanyo ea khatello, valve ena e sebelisoa lits'ebetsong tse thata tsa indasteri:

• Mechini e Meholo ea Phetiso le Kabo ea Metsi: Ho arola likarolo tsa liphaephe tse kholo.
• Li-Power Plant: Litsamaiso tsa metsi a pholileng, mela ea metsi a fepeloang.
• Metsi a Ts'ebetso ea Liindasteri: Limela tse kholo tsa indasteri.
• Limela tsa ho tlosa letsoai metsing: Mela e nang le khatello e phahameng ea reverse osmosis (RO).
• Merafo le Tsamaiso ea Liminerale: Liphaephe tsa lerōle (ka khetho e nepahetseng ea thepa).

5. Melemo le Mathata

6. Lintho tsa Bohlokoa Tse ka Etsoang Bakeng sa Khetho le Tšebeliso

• Khetho ea Thepa: Kopanya thepa ea 'mele/wedge/setulo (WCB, WC6, CF8M, jj.) le tšebeletso ea mokelikeli (metsi, ho bola, mocheso).
• Dikgokelo tsa Qetello: Netefatsa hore maemo a flange le sefahleho (RF, RTJ) di tsamaellana le phaephe.
• Yuniti ea Matla a Hydraulic (HPU): Valve e hloka HPU e arohaneng ho hlahisa khatello ea hydraulic. Nahana ka lebelo le hlokahalang la ts'ebetso, khatello le taolo (ea lehae/e hole).
• Mokhoa o Sireletsehileng oa ho hloleha: Sesebelisoa sa ho sebetsa se ka hlalosoa e le Fail-Open (FO), Fail-Closed (FC), kapa Fail-in-Last-Position (FL) ho latela litlhoko tsa polokeho.
• Valve e Fetileng ka Nako: Bakeng sa lits'ebetso tse nang le khatello e phahameng, valve e nyane e fetileng ka nako (mohlala, DN50) hangata e kenngoa ho leka-lekanya khatello ho pholletsa le wedge pele e bula valve e kholo, e fokotsang torque e hlokahalang ea ts'ebetso.

Ka bokhutšoanyane, Hydraulic Wedge Gate Valve DN400 PN25 ke mosebetsi o boima, o sebetsang hantle bakeng sa ho emisa kapa ho qala phallo ea metsi ka botlalo liphaepheng tse kholo, tse nang le khatello e phahameng. Ts'ebetso ea eona ea hydraulic e etsa hore e lokele libaka tsa ho itšehla thajana tse hole kapa tse ikemetseng.
