The utility model solves the technological scheme that its technical problem adopts: a kind of float ball type steam drain regulating valve, comprise the valve gap, valve body and the valve seat that set gradually from top to bottom, on described valve seat, level is provided with water intake, is vertically provided with water outlet on valve seat, and valve seat is provided with valve plate block; On described valve body, level is provided with condensation-water drain, at condensation-water drain, is movably equipped with drain plug; Described valve gap top is provided with steam inlet, and valve gap inwall is provided with liquid level sensor and ball float support, and valve gap is built-in with ball float, and described ball float one end is connected with valve rod, and valve rod enters in valve seat through valve body, and the valve rod the other end is connected with valve plate.
Further, the distance of described liquid level sensor and steam inlet is 110-125mm.
Further, described valve body bottom is provided with block, between block and valve rod, is provided with sealing layer.
Further, described valve plate block is positioned at directly over water outlet, and valve plate block is embedded with seal ring.
Further, described valve gap offers the groove of placing seal ring at steam inlet place.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, and working pressure is high, good seal performance, and compact structure, is easy to cleaning, wear-resistant long service life.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. valve gaps in figure, 2. valve body, 3. valve seat, 4. water intake, 5. water outlet, 6. valve rod, 7. valve plate, 8. seal ring, 9. condensation-water drain, 10. drain plug, 11. ball floats, 12. ball float supports, 13. liquid level sensors, 14. steam inlets, 15. grooves, 16. valve plate blocks, 17. sealing layers, 18. blocks.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Float ball type steam drain regulating valve as shown in Figure 1, comprises the valve gap 1, valve body 2 and the valve seat 3 that set gradually from top to bottom, and on valve seat 3, level is provided with water intake 4, is vertically provided with water outlet 5 on valve seat 3, and valve seat 3 is provided with valve plate block 16; On valve body 2, level is provided with condensation-water drain 9, at condensation-water drain 9, is movably equipped with drain plug 10; Valve gap 1 top is provided with steam inlet 14, and valve gap 1 inwall is provided with liquid level sensor 13 and ball float support 12, and valve gap 1 is built-in with ball float 11, and ball float 11 one end are connected with valve rod 6, and valve rod 6 enters in valve seat 3 through valve body 2, and valve rod 6 the other ends are connected with valve plate 7.
Liquid level sensor 13 is 110mm with the distance of steam inlet 14; Valve body 2 bottoms be provided with block (18, between block 18 and valve rod 6, be provided with sealing layer 17; Valve plate block 16 is positioned at directly over water outlet 5, and valve plate block 16 is embedded with seal ring 8; Valve gap 1 offers the groove of placing seal ring at steam inlet 14 places.
1. valve gap, 2. valve body, 3. valve seat, 4. water intake, 5. water outlet, 6. valve rod, 7. valve plate, 8. seal ring, 9. condensation-water drain, 10. drain plug, 11. ball floats, 12. ball float supports, 13. liquid level sensors, 14. steam inlets, 15. grooves, 16. valve plate blocks, 17. sealing layers, 18. blocks.
