Description
Technical field
The utility model relates to valve technology field, especially a kind of Novel steam reduction valve.
Background technique
The piston of traditional relief valve is not sealing often, and when being subject to steam medium pressure, valve easily lost efficacy.
Summary of the invention
For addressing the above problem, the utility model provides a kind of Novel steam reduction valve, described a kind of Novel steam reduction valve, it is characterized in that, comprise: valve body 1, valve gap 2, piston 3, cylinder 4, piston ring 5, main valve 6, main spool spring 7, main valve seat 8, integrated pulse valve core 9, sentinel valve valve seat 10, sentinel valve spring 11, diaphragm 12, Regulation spring 13, adjusting screw 14, cap 15, plug screw 16, end cap 17, pad 18, pad 19, pulse chamber 20, outlet passage 21, inlet passage 22, import 23, outlet 24, the spherical spool 25 of arc, described a kind of Novel steam reduction valve, on cylinder 4, be provided with piston ring 5, its piston ring 5 is graphite material making, can produce seal action.
Its workflow is: when pressure medium enters inlet passage 22 from import 23, because pressure medium backs down integrated pulse valve core 9, drive piston 3, open main valve 6, medium flows to outlet 24 by import 23, and now pulse chamber's 20 media enter diaphragm 12 belows, when its pressure is enough, diaphragm 12 moves up, integrated pulse valve core 9 is closed gradually, the medium that flows into piston 3 is reduced gradually, pressure drop, so repeatedly, reach the effect of decompression.Described a kind of Novel steam reduction valve is provided with piston ring 5 on cylinder 4, and its piston ring 5 is made for graphite material, can produce seal action, when piston 3, opens main valve 6, is provided with piston ring 5 and can produces seal action on cylinder 4.
The utility model effect is: 1. produce sealing, reduce surface of contact, reduce wear; 2. can self repair; 3. corrosion-resistant and be easy to clean; 4. be convenient to install, overhaul, dismantle; 5. rational in infrastructure, beautiful shape, lightweight.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Wherein: valve body 1, valve gap 2, piston 3, cylinder 4, piston ring 5, main valve 6, main spool spring 7, main valve seat 8, integrated pulse valve core 9, sentinel valve valve seat 10, sentinel valve spring 11, diaphragm 12, Regulation spring 13, adjusting screw 14, cap 15, plug screw 16, end cap 17, pad 18, pad 19, pulse chamber 20, outlet passage 21, inlet passage 22, import 23, outlet 24, the spherical spool 25 of arc.
Embodiment
As shown in the figure, described a kind of Novel steam reduction valve is provided with piston ring 5 on cylinder 4, and its piston ring 5 is made for graphite material, can produce seal action.
Its workflow is: when pressure medium enters inlet passage 22 from import 23, because pressure medium backs down integrated pulse valve core 9, drive piston 3, open main valve 6, medium flows to outlet 24 by import 23, and now pulse chamber's 20 media enter diaphragm 12 belows, when its pressure is enough, diaphragm 12 moves up, integrated pulse valve core 9 is closed gradually, the medium that flows into piston 3 is reduced gradually, pressure drop, so repeatedly, reach the effect of decompression.Described a kind of Novel steam reduction valve is provided with piston ring 5 on cylinder 4, and its piston ring 5 is made for graphite material, when piston 3, opens main valve 6, is provided with piston ring 5 and can produces seal action on cylinder 4.The utility model effect is: 1. produce sealing, reduce surface of contact, reduce wear; 2. can self repair; 3. corrosion-resistant and be easy to clean; 4. be convenient to install, overhaul, dismantle; 5. rational in infrastructure, beautiful shape, lightweight.
