Guider is located at the inside of middle straight section, and its lower limb carries out sealing welding with middle straight section lower end inside, weldering
Meet place to be located at below osculum；Guider makes the steam water interface entering from steam inlet form the air-flow that rotates in a circumferential direction,
Centrifugal action is relied on to carry out steam-water separation in space between guider and middle straight section；
Upper conical-tube above the inside of middle straight section, guider, launch by the upper end contraction mouth of upper conical-tube and lower end
Mouth carries out sealing welding with inside upper end cover and middle straight section respectively.
Further,
Guider includes slower conical tube, air-flow break-in section, cap from bottom to top；The lower end deployment opening edge of slower conical tube and with
Middle straight section lower end inside sealing welding, weld is located under osculum；The upper end contraction mouth docking air-flow break-in of slower conical tube
Section；The side of air-flow break-in section is provided with multiple air stream outlets, and tiltedly sets within one week multiple flow rotations along air-flow break-in section side and lead
Leaf, the yawing moment of flow rotation stator consistent so that the steam water interface shape that exports out from air-flow break-in section side airflow
Circumferentially swirling eddy；Cap is connected to above air-flow break-in section.
Further, steam inlet, middle straight section, guider, upper conical-tube and steam (vapor) outlet are co-axially mounted.
Further, cap is shaped as taper.
The utility model has the advantage of：
1）Structure is simple, processing and manufacturing difficulty is low, it is to avoid the defect such as the pore producing because of casting, crackle, burning into sand, its
Intensity can be controlled by the calculating standard of national professional field, runs more safe and reliable.
2）Rational in infrastructure, steam-water separation effect is very good.
Brief description
Fig. 1 is structure composition schematic diagram of the present utility model.
Fig. 2 is the A-A of Fig. 1 to sectional view.
Specific embodiment
With reference to concrete drawings and Examples, the utility model is described in further detail.
The utility model proposes direct current cooker vertical steam-water separator end cover type expander, including：Steam inlet 1, under
End cap 2, osculum 3, middle straight section 4, guider 5, upper conical-tube 6, upper end cover 7 and steam (vapor) outlet 8；
Upper end cover 7 and bottom end cover 2 are located at the upper/lower terminal of middle straight section 4 respectively, and with the butt welding of middle straight section 4；Under
The center of end cap 2 and upper end cover 7 is respectively equipped with steam inlet 1 and steam (vapor) outlet 7；
Have osculum 3 in the lower end of middle straight section 4 near the commissure with bottom end cover 2, separate for discharge
Water；
Guider 5 is located at the inside of middle straight section 4, and its lower limb carries out sealing welding with middle straight section 4 lower end inside,
Weld must be positioned at below osculum 3, so that the enough in-lines of the water energy separating are discharged；
Upper conical-tube 6 is located at the inside of middle straight section 4, above guider 5, the upper end contraction mouth of upper conical-tube 6 and lower end
Deployment opening carries out sealing welding with inside upper end cover 7 and middle straight section 4 respectively；It is easy to the discharge upwards of steam；And steam inlet
1st, middle straight section 4, guider 5, upper conical-tube 6 and steam (vapor) outlet 8 are co-axially mounted.
Guider 5 includes slower conical tube 51, air-flow break-in section 52, cap 53 from bottom to top；The lower end of slower conical tube 51 is launched
Mouthful edge and with middle straight section 4 lower end inside sealing welding, weld is located under osculum 3；The upper end of slower conical tube 51 is shunk
Mouth docking air-flow break-in section 52；As shown in Fig. 2 the side of air-flow break-in section 52 is provided with multiple air stream outlets, and along air-flow break-in
Section 52 side tiltedly sets multiple flow rotation stators 521 for one week, and the yawing moment of flow rotation stator 521 is consistent, so that from
The steam water interface that air-flow break-in section 52 side airflow exports out forms the air-flow that rotates in a circumferential direction；Cap 53 is connected to air-flow break-in
Above section 52, prevent steam from directly rising, reduce the steam axial direction rate of climb, improve steam-water separation effect；Cap 53 is shaped as
Taper is so that the steam entrance upper conical-tube 6 after separating is more smooth；
Utility model works principle and work process：
Steam water interface enters guider 5 from the steam inlet 1 of bottom end cover, is formed and rotate in a circumferential direction after guider 5
Air-flow, relies on centrifugal action to carry out steam-water separation in the space between guider 5 and middle straight section 4, the water separating
Discharge through middle straight section 4 bottom osculum 3, the steam separated upwards through upper conical-tube 6 from steam (vapor) outlet 8 row of upper end cover
Go out, to reach the purpose of steam-water separation.
Upper conical-tube 6 can reduce the resistance of steam outflow, improves steam-water separation efficiency.
