Ki sa ki Valv Globe Kalite Ang?

Yon valv glòb se yon valv mouvman lineyè ki itilize pou sispann, kòmanse, ak kontwole koule likid la. Ka disk valv glòb la dwe retire antyèman nan chemen an koule, oswa li ka konplètman fèmen chemen an koule. Pandan ouvèti a ak fèmen nan valv la, disk la deplase pèpandikilè nan chèz la.

Mouvman sa a kreye espas annulaire ant disk la ak bag chèz ki piti piti fèmen kòm valv la fèmen. Karakteristik sa a bay valv la glòb bon throttling kapasite ki nesesè pou reglemante koule a.

Flit soti nan chèz la valv glòb se mwens kòm konpare ak valv la pòtay, sitou akòz kontak ang dwat ant disk la ak bag chèz, ki pèmèt sele pi sere ant chèz la ki gen kapasite.

Kalite ang Globe Valv

Angle Kalite Globe Valv vire direksyon koule a pa 90 degre san yo pa itilize yon koud ak yon tiyo siplemantè soude. Disk louvri kont koule a. Sa a kalite valv glòb ka itilize nan kondisyon an koule fluktue tou, menm jan yo kapab manyen efè a slugging.

Aplikasyon nan valv Globe

Valv Globe yo itilize nan sistèm yo kote kontwòl koule yo mande epi sere koule enpòtan tou.

•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.

Avantaj

•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

Dezavantaj

•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.
