Check Valve and Globe Valve related presentations

Valve is a fluid conveying system control unit, with a deadline, regulation, diversion, to prevent reflux, regulation,diversion or overflow relief functions. Valves for fluid control systems, from simple to highly complex valve automationsystems used in a variety of valves, a considerable variety of its varieties and specifications. The valve can be used to control air, water, steam, a variety of corrosive media, mud, oil, metals and radioactive liquid media and other types offluid flow.Valve was divided into  Check Valve , ball valves, butterfly valves and so on.

Ball, GB/T21465-2008 "valves term" is defined as: opening and closing pieces (ball) driven by the stem and around the stemaxis for rotation of the valve. Cut off or connected to the main pipeline for the media, can be used for fluid regulation andcontrol, which seal their V-ball V-ball of the metal core and between the valve seat hardfacing alloy has a strong shear force, especially suitable for fiber, small solid pieces of material and other media. The multi-way valve in the pipeline, not only the flexibility to control the convergence of media, streaming, and the flow switch, while also leaving off any channelconnected to the other two channels.  Globe Valve  in the pipe in the general category should be installed horizontally.

Butterfly valve is closed parts (valve flap or disc) for the disc, around the valve axis to achieve the opening and closing avalve, cut off from the main pipe and throttle use. Valve opening and closing piece is a disc-shaped disc, the valve bodyaround its own axis of rotation, or adjustments to achieve the purpose of opening and closing. Valve fully open to fully closed is usually less than 90 °, and the butterfly valve lever itself is not self-locking capability, in order to positiondisc to install on worm gear reducer in the stem. The use of worm gear reducer, not only can make the butterfly plate with self-locking capability, so that disc to stop at any position, but also to improve the operational performance of the valve.

Industry-specific features to high temperature valve for higher pressure range, the valve nominal diameter large, carbon steelvalve body, valve plate metal ring instead of the rubber seal ring. Large  Gate Valve  with steel plate welded high-temperature manufacturing, mainly for high-temperature medium duct smoke and gas pipelines.
