Wherein, described steam cavity one end arranges nozzle, and nozzle is positioned at housing, and the other end arranges end cap, and end cap is connected with housing.
Wherein, circular the first seal ring is set between described end cap and housing, circular the second seal ring is set between described nozzle and housing.
Wherein, on described steam cavity, be provided with steam inlet, described steam inlet is connected with external source of high pressure steam.
Wherein, axial and described steam cavity and the mixing chamber of described vacuum cavity is axial vertical.
Wherein, one end of described mixing chamber arranges trunnion, and trunnion is near described steam cavity, and the mixing chamber the other end arranges mixed export, and mixed export is positioned at outside housing.
(3) beneficial effect
The vapor pump that technique scheme provides, efficiency simple in structure, non-maintaining, sample gas disposal greatly improves, and is widely used in the sampling of the oxygen analysis system of coke-stove gas, semi-water gas; Improve the extensive adaptability of sample gas under the reliability of sample gas processing system, few maintainability, mal-condition, sample gas disposal analytical system is core and the key technology of on-line analysis system, and therefore this programme is also playing a significant role aspect raising on-line analysis system quality and quality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment vapor pump.
Wherein, 1: end cap; 2: the first seal rings; 3: housing; 4: steam cavity; 5: nozzle; 6: the second seal rings; 7: vacuum cavity; 8: sample gas entrance; 9: trunnion; 10: mixing chamber; 11: mixed export; 12: steam inlet.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The utility model relates to the aspirator of a kind of technological process gas pressure in-10KPa to 15KPa scope, is called vapor pump, and the utility model is for the sample gas processing system design of on-line gas analysis system, is the very important parts of sample gas processing system.
Shown in Fig. 1, in the present embodiment vapor pump, end cap 1, the first seal ring 2, housing 3, nozzle 5, the second seal ring 6, steam inlet 12 form steam cavity 4, housing 3, sample gas entrance 8, trunnion 9 form vacuum cavity 7, and housing 3, trunnion 9, mixed export 11 form mixing chamber 10; Nozzle 5, trunnion 9 are replaceable.
Particularly, steam cavity 4 is positioned at described housing 3 one end, mixing chamber 10 is positioned at described housing 3 the other ends, it is vacuum cavity 7 that steam cavity 4 exports between mixing chamber 10 entrances, steam cavity 4 and mixing chamber 10 coaxially arrange, the external source of high pressure steam of steam cavity 4, is provided with sample gas entrance 8 on vacuum cavity 7, be provided with mixed export 11 on mixing chamber 10.
Described steam cavity 4 one end arrange nozzle 5, and nozzle 5 is positioned at housing 3, and the other end arranges end cap 1, and end cap 1 is connected with housing 3.Circular the first seal ring 2 is set between described end cap 1 and housing 3, circular the second seal ring 6 is set between described nozzle 5 and housing 3.On described steam cavity 4, be provided with steam inlet 12, described steam inlet 12 is connected with external source of high pressure steam; Described vacuum cavity 7 axially and described steam cavity 4 and mixing chamber 10 axial vertical; One end of described mixing chamber 10 arranges trunnion 9, and trunnion 9 is near described steam cavity 4, and mixing chamber 10 the other ends arrange mixed export 11, and mixed export 11 is positioned at outside housing 3.
