Globe valve structure and installation precautions

Globe valve structure: Globe valve body structure of the straight-through type, direct current and right angle. Straight-through is the most common structure, but its resistance to fluids is greatest. Direct flow fluid resistance is small, more for solid particles or viscous fluid. Right-angle valve body forgings, for smaller, higher pressure of the globe valve. Shut-off valve installation and maintenance should note the following: 1, handwheel, handle the operation of the globe valve can be installed in any position on the pipeline. 2, hand wheel, handle and Wei moving mechanism, do not allow lifting. 3, the flow of medium should be consistent with the arrow direction shown by the valve body. Globe valve main criteria: 1, GB / T12233-2006 "universal valve iron stop valve and lifting check valve" 2, GB / T12235-2007 "universal valve flange connection steel stop valve and lifting check valve" 3, JB / T53174-94 "cut-off valve product quality classification" 4, JB / T53165-92 "high pressure balance valve" 5, GB / T587-2008 "marine flange bronze globe valve" 6, GB / T590-2008 "Marine flange cast iron globe valve" 7, GB / T8464-2008 "Iron and copper threaded connection valve" 8, GB8465.2-87 "Female threaded gate valve, globe valve, ball valve, check valve Basic Size Iron Shut-off valve"
