Milestone is Stainless Steel Angle Globe Valve manufacturers and suppliers in China who can wholesale Stainless Steel Angle Globe Valve. We can provide professional service and better price for you. If you interested in Stainless Steel Angle Globe Valve products, please contact with us. We follow the quality of rest assured that the price of conscience, dedicated service.Stainless Steel Angle Globe Valve may be used for most duties encountered in fluid handling process piping systems.Although the Stainless Steel Angle Globe Valve can be used as a block or isolation valve, it is primarily designed to regulate flow in the partially open position, while Stainless Steel Angle Globe Valve are designed for either the fully opened or fully closed position.When considering Stainless Steel Angle Globe Valve for on-off isolation service, design selection should receive careful consideration because maintaining a tight seal against the strong force pushing up on the disc is difficult.The Stainless Steel Angle Globe Valve, compared to the gate valve, has a short stem travel between the open and closed positions, has relatively little wear and is easier to repair

The double-acting throttling stop valve also has a multi-stage throttling function, a large throttling pressure difference, and can be used for throttling and shutoff under high pressure.The packing adopts a V-shaped packing structure with self-sealing ability, which requires no adjustment and is extremely easy to open and close. The stuffing box is equipped with an auxiliary sealing grease injection structure to ensure reliable sealing performance of the valve packing. This valve can be repaired online, and the pipeline can be replaced with packing and other wearing parts under pressure.This valve is equipped with a larger drain hole at the bottom of the valve. If necessary, open it to clean the dirt in the valve.Stainless Steel Angle Globe Valve are linear motion closing-down valves in which the closure member is moved squarely on and off the seat. Usually the closure member is referred as a disc, irrespective of its shape. The seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate. Cast Steel Globe Valves are most suitable for throttling and controlling fluid flow and are generally employed in small size piping.Stainless Steel Angle Globe Valve design necessitates two changes in the direction of flow and this causes resistance in liquid lines and objectionable pressure drop. The installation of Stainless Steel Angle Globe Valve is made so that the flow is up through the seat ring and against the bottom of the disc. This prevents accumulation of dirt and debris above the disc.

Pracovní princip úhlového kulového ventilu z nerezové oceli

Uzavírací ventil z ocelolitiny se skládá z pohyblivého kotouče a pevného prstencového sedla umístěného ve zhruba kulovém tělese. Je určen především k zastavení, spuštění a regulaci průtoku. Je umístěn uprostřed potrubí a rovnoběžně s potrubím. Otvor na sedle ventilu je uzavřen kotoučem ventilu. . Při ručním otáčení rukojetí nebo pomocí pohonu se kotouč ventilu spouští nebo zvedá dříkem ventilu. Když je kotouč ventilu zcela spuštěn, průtok kapaliny se přeruší. Když je disk zcela zvednutý, průtok tekutiny dosáhne maximální rychlosti. Když se kotouč zvedne pod maximální úroveň, průtok tekutiny se nastaví úměrně svislému pohybu kotouče.
