X'inhu Angolu Tip Globe Valve?

Valv globu huwa valv ta 'moviment lineari użat biex iwaqqaf, jibda, u jirregola l-fluss tal-fluwidu. Id-diska tal-valv tal-globu tista 'titneħħa kompletament mill-mogħdija tal-fluss, jew tista' tagħlaq kompletament il-mogħdija tal-fluss. Matul il-ftuħ u l-għeluq tal-valv, id-diska timxi perpendikolarment mas-sedil.

Dan il-moviment joħloq l-ispazju annulari bejn id-diska u ċ-ċirku tas-sedil li jagħlaq gradwalment hekk kif il-valv jingħalaq. Din il-karatteristika tipprovdi l-abbiltà ta 'throttling tajba tal-valv tal-globu meħtieġa biex tirregola l-fluss.

It-tnixxija mis-sedil tal-valv tal-globu huwa inqas meta mqabbel mal-valv tal-bieb, prinċipalment minħabba kuntatt ta 'angolu rett bejn id-diska u ċ-ċirku tas-sedil, li jippermetti siġill aktar strett bejn is-sedil tad-diska.

Tipi ta 'angolu Globe Valve

Angle Type Globe Valve iddawwar id-direzzjoni tal-fluss b'90 grad mingħajr ma tuża minkeb u weldjatura ta 'pajp wieħed żejjed. Diska miftuħa kontra l-fluss. Dan it-tip ta 'valv globu jista' jintuża wkoll fil-kondizzjoni tal-fluss li jvarja, peress li huma kapaċi jimmaniġġjaw l-effett slugging.

Applikazzjoni tal-valv Globe

Globe Valves jintużaw fis-sistemi fejn il-kontroll tal-fluss huwa meħtieġ u l-issikkar tat-tnixxija huwa importanti wkoll.

•It used in high-point vents and low-point drains when leak tightness and safety are major concerns. Otherwise, you can use a gate valve for drain and vent.

•It can be used in Feed-water, chemical, air, lube oil and almost all services where pressure drop is not an issue

•This valve is also used as an automatic control valve, but in that case, the stem of the valve is a smooth stem rather than threaded and is opened and closed by lifting action of an actuator assembly.

Vantaġġi

•Better shut off as compared to gate valve

•Good for frequent operation as no fear of wear of seat and disk

•Easy to repair, as seat and disk can be accessed from the valve top

•Fast operation compares to gate valve due to shorter stroke length

•Usually operated by an automatic actuator

Żvantaġġi

•High head loss from two or more right-angle turns of flowing fluid within the valve body.

•Obstructions and discontinuities in the flow path lead to a high head loss.

•In a large high-pressure line, pulsations and impacts can damage internal trim parts.

•A large valve requires considerable power to open and create noise while in operation.

•It is heavier than other valves of the same pressure rating.
