Abstract
The utility model discloses a kind of oxygen rifle nitrogen seal ring cap, comprise nitrogen seal ring cap cap body, on cap body bottom pyramidal periphery, uniform interval arranges 12 purge holes, and cap body bottom pyramidal periphery is horizontally disposed with an annular groove, and 12 described purge holes are positioned at this annular groove.Adopt the utility model structure, no matter how nitrogen sealing cap rotates on oxygen rifle, oxygen rifle is when lower rifle, nitrogen sealing cap covers 12 holes uniform on oxygen muzzle nitrogen seal device and all can be covered by the annular groove on nitrogen sealing cap, thus effectively dock with a hole, 12 on nitrogen sealing cap, nitrogen conducts by annular groove, and therefore sealing effectiveness just improves greatly, effective control obnoxious flavour and dust, to the pollution of environment, prevent field personnel's carbon monoxide poisoning.
Description
Technical field
The utility model relates to a kind of oxygen rifle nitrogen seal ring cap of making steel.
Background technology
Converter, in the process of blowing decarburization, produces a large amount of high-temperature flue gas and the dust that contain CO inflammable gas.Oxygen rifle nitrogen sealing cap is for blocking the oxygen muzzle fixed on I section of flue, adopt by 12 hole ejection nitrogen uniform on oxygen muzzle nitrogen seal device simultaneously, to oxygen muzzle nitrogen seal device and nitrogen sealing cap, sealing gap between nitrogen sealing cap and oxygen rifle, thus effectively control obnoxious flavour and dust, to the pollution of environment, prevent field personnel's carbon monoxide poisoning.
The situation of prior art is: because nitrogen sealing cap is rotatable on oxygen rifle, oxygen rifle is when lower rifle, when nitrogen sealing cap covers on oxygen muzzle nitrogen seal device, 12 holes uniform on oxygen muzzle nitrogen seal device can not effectively be docked with a hole, 12 on nitrogen sealing cap, nitrogen can only be conducted by its gap, therefore sealing effectiveness just reduces greatly, effectively can not control obnoxious flavour and dust to the pollution of environment.
Summary of the invention
The purpose of this utility model is to provide a kind of oxygen rifle nitrogen seal ring cap, effectively can improve sealing effectiveness, and effectively control obnoxious flavour and dust are to the pollution of environment.
The purpose of this utility model realizes like this, a kind of oxygen rifle nitrogen seal ring cap, comprise nitrogen seal ring cap cap body, on cap body bottom pyramidal periphery, uniform interval arranges 12 purge holes, cap body bottom pyramidal periphery is horizontally disposed with an annular groove, and 12 described purge holes are positioned at this annular groove.
Adopt the utility model structure, no matter how nitrogen sealing cap rotates on oxygen rifle, oxygen rifle is when lower rifle, nitrogen sealing cap covers 12 holes uniform on oxygen muzzle nitrogen seal device and all can be covered by the annular groove on nitrogen sealing cap, thus effectively dock with a hole, 12 on nitrogen sealing cap, nitrogen conducts by annular groove, and therefore sealing effectiveness just improves greatly, effective control obnoxious flavour and dust, to the pollution of environment, prevent field personnel's carbon monoxide poisoning.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view;
Fig. 2 is main TV structure schematic diagram of the present utility model.
Embodiment
A kind of oxygen rifle nitrogen seal ring cap, as shown in Figure 1 and Figure 2, comprise nitrogen seal ring cap cap body 2, on cap body 2 bottom pyramidal periphery, uniform interval arranges 12 purge holes 3, cap body 2 bottom pyramidal periphery is horizontally disposed with an annular groove 1, and 12 described purge holes 3 are positioned at this annular groove 1.
Claims (1)
1. an oxygen rifle nitrogen seal ring cap, comprise nitrogen seal ring cap cap body, on cap body bottom pyramidal periphery, uniform interval arranges 12 purge holes, it is characterized in that: on cap body bottom pyramidal periphery, be horizontally disposed with an annular groove, and 12 described purge holes are positioned at this annular groove.
