Cad é Comhla Globe Cineál Uillinn?
Is comhla tairiscint líneach é comhla cruinne a úsáidtear chun an sreabhadh sreabhach a stopadh, a thosú agus a rialáil. Is féidir an diosca comhla cruinne a bhaint go hiomlán as an gcosán sreafa, nó féadfaidh sé an cosán sreafa a dhúnadh go hiomlán. Le linn an chomhla a oscailt agus a dhúnadh, bogann an diosca go hingearach leis an suíochán.
Cruthaíonn an ghluaiseacht seo an spás annular idir an diosca agus an fáinne suíocháin a dhúnann de réir a chéile nuair a dhún an comhla. Soláthraíonn an tréith seo cumas smeartha maith don chomhla cruinne atá riachtanach chun an sreabhadh a rialú.
Tá an sceitheadh ó shuíochán comhla cruinne níos lú i gcomparáid leis an gcomhla geata, go príomha mar gheall ar theagmháil uillinn ceart idir an diosca agus an fáinne suíocháin, rud a fhágann go bhfuil séala níos déine idir suíochán an diosca.
Cineálacha uillinn Globe Comhla
Déanann Comhla Globe Cineál Uillinn an treo sreafa 90 céim gan úsáid a bhaint as uillinn agus táthú píopa breise amháin. Diosca oscailte i gcoinne an sreabhadh. Is féidir an cineál comhla cruinne seo a úsáid sa riocht sreafa luaineach freisin, toisc go bhfuil siad in ann an éifeacht slugging a láimhseáil.
Feidhm comhla Globe
Úsáidtear Comhlaí Cruinneog sna córais ina bhfuil gá le rialú sreafa agus tá tightness sceite tábhachtach freisin.
•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.
Buntáistí
•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
Míbhuntáistí
•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.
•Costlier compared to the gate valve.
