The Opening and Closing Parts of Stainless Steel Threaded Gate Valve Are Plug-Shaped Valve Clack, the Sealing Surface Is Flat Or Conical, and the Valve Clack Moves Linearly along the Center Line of the Fluid. The Movement Form of the Valve Stem Is Lift Rod (the Valve Stem Is Lifted and the Handwheel Is Not Lifted), and There Is Also Rotary Bar (the Handwheel and the Valve Stem Are Spinning Lift Together, and the Nut Is Located on the Valve Body). Corrugated Pipe Stop Valve Is Only Applicable to Full Opening and Full Closing, and Adjustment and Throttling Are Not Allowed. This Type of Valve Should Be Installed Horizontally in the Pipeline.
Stainless SteelThreaded gate valve,Internal Thread Gate Valve,High Pressure Gate Valve,Corrugated Pipe Stop ValveIt Is a Forced Sealing Valve, So When the Valve Is Closed, Pressure Must Be Applied to the Valve Flap to Force the Sealing Surface Not to Leak. When the Medium Enters Valve 6 from below the Disc, the Operating Force Is Required.OvercomeThe Resistance Is the Friction Force of the Valve Stem and Packing and the Thrust Generated by the Pressure of the Medium. the Force of Closing the Valve Is Larger than That of Opening the Valve, So the Diameter of the Valve Stem Is Larger, otherwise, the Top Bend of the Valve Stem Will Fail. In Recent Years, after the Emergence of the Self-Sealing Valve, the Medium Flow Direction of the Stop Valve Changes from above the Valve Disc to the Valve Chamber. at This Time, under the Action of Medium Pressure, the Force of Closing the Valve Is Small, while the Force of Opening the Valve Is Large, the Diameter of the Valve Stem Can Be Reduced Accordingly. At the Same Time, under the Action of Medium, This Form of Valve Is Also Relatively Tight. China's Valve "Three Chemical Supply" Once Stipulated That the Flow Direction of Stop Valves Should Be from Top to Bottom.
When the Internal Thread Gate Valve Is Opened, When the Opening Height of the Disc Is 25% ~ 30% of the Nominal Diameter, the Flow Has Reached the Maximum, Indicating That the Valve Has Reached the Fully Open Position. Therefore, the Fully Open Position of the Stop Valve Should Be Determined by the Stroke of the Valve Disc.
