Stainless steel flange globe valve features and working principle

2018-12-18

Stainless steel flange shut-off valve Many times we call the stainless steel shut-off valve, the valve flange connection. Stainless steel globe valve belongs to the globe valve, the valve body adopts 301,304,316 stainless steel, stainless steel globe valve is widely used in chemical industry, shipbuilding, food machinery and other industries. Stainless steel flange cut-off valve features: (1) the structure is simpler than the gate valve, manufacturing and maintenance are more convenient; (2) the sealing surface is not easy to wear and abrasion, good sealing, opening and closing valve and valve sealing surface (3) When opening and closing, the valve stroke is small, so the cut-off valve height is smaller than the gate valve, but the structure length is longer than the gate valve; (4) (5) the fluid resistance is large, because the valve body is more tortuous media channels, fluid resistance, power consumption; (6) the nominal flow direction of the media PN ≤ 16MPa When the general flow downstream, the media from the valve up to the next flow; nominal pressure PN ≥ 20MPa, the general use of counter-current, the media flow down from the valve above. To increase the seal can. When used, the globe valve medium can only flow in one direction, can not change the flow direction; (7) when the valve is fully open erosion. Stainless steel flange shut-off valve once opened, the valve seat and the disc sealing surface between the no longer contact, so its sealing surface mechanical wear and tear less, as most of the globe valve seat and the valve is relatively easy Repair or replacement of the sealing element does not require removal of the entire valve from the pipeline, which is very suitable for the welding of valves and pipelines. The flow direction of the medium as it passes through such a valve changes, so the shut-off valve has a higher flow resistance than the other valves.
