Description
Technical field
The utility model relates to valve technology field, especially a kind of novel gas special valve.
Background technique
Conventional pipelines gas burning special valve, due to reason being set, is difficult to rapid pressure release, is difficult to guarantee pipeline pressure, particularly carries hazmat, is difficult to guarantee as hazardous chemical visual plant safety such as rock gas, crude oil and refinery.
Summary of the invention
For addressing the above problem, the utility model provides a kind of novel gas special valve, described a kind of novel gas special valve, it is characterized in that, comprise: filtration under diminished pressure plate 1, underpressure chamber 2, metal corrugated plate 3, valve body 4, damping chamber 5, deceleration piece 6, deceleration runner 7, pressure regulation cock 8, import 9, pressure relief opening 10, pressure adjusting bolt 11, sheet metal 12, described a kind of novel gas special valve, in valve body 4 lower ends, be provided with filtration under diminished pressure plate 1, described deceleration piece 6 is wire netting making, its filtration under diminished pressure plate 1 is filter medium slag, keeps valve clean.
Described a kind of novel gas special valve, in valve body 4 lower ends, be provided with filtration under diminished pressure plate 1, its filtration under diminished pressure plate 1 filter medium slag, in filtration under diminished pressure plate 1 upper end, be provided with underpressure chamber 2, in underpressure chamber, 2 upper ends are provided with metal corrugated plate 3, in the middle of metal corrugated plate 3, be provided with deceleration runner 7 and pressure regulation cock 8, in metal corrugated plate 3 upper ends, be provided with damping chamber 5, in 5 upper ends, damping chamber, be provided with deceleration piece 6, in the middle of deceleration piece 6, be provided with sheet metal 12, in the middle of sheet metal 12, be provided with pressure relief opening 10 and pressure adjusting bolt 11.
Described a kind of novel gas special valve is arranged on the welded flange opening of pipeline upper end, its valve body lower end is connected with pipeline, its pressure regulation cock 8 and pressure adjusting bolt 11 are pressed safety pressure, carry out own wt adjustment and accept the ratio setting of calculation of pressure, when pressure medium and erosion gas enter after pipeline, affecting pipeline medium carries, described a kind of novel gas special valve is according to pressure medium, automatically adjutage track media pressure balance, get rid of piping erosion gas, guarantee pipeline pressure balance, prevent pipe explosion.
Its a kind of novel gas special valve workflow: after pipeline medium Overpressure of a safety valve or gaseous impurity etc. enter, automatically enter valve body import 9, after its filtration under diminished pressure plate 1 filter medium slag, medium is by underpressure chamber 2, enter deceleration runner 7, its pressure Overpressure of a safety valve regulation cock 8 deadweights, automatically back down pressure regulation cock 8, when medium enters behind damping chamber 5, the deceleration piece 6 of its 5 upper ends, damping chamber, adjust flowing medium direction, directly from pressure relief opening 10, discharge, the medium of Overpressure of a safety valve, can automatically back down pressure adjusting bolt 11, automatically adjutage track media pressure balance, get rid of piping erosion gas, guarantee pipeline pressure balance, prevent pipe explosion.
The utility model effect is: 1. rational in infrastructure, beautiful shape, lightweight, prevents pipe explosion; 2. be convenient to install, overhaul, dismantle, 3. corrosion-resistant, resistance to burning, resistance to quick-fried, is easy to clean.
