Description
Technical field
The utility model relates to the valve technology field of heating equipment, specifically, relates to a kind of high temperature resistance antiscour soft seal air reversing valve.
Background technique
In industrial combustion furnace system, in order to circulation and the cut-out of air dielectric can be controlled, general employing selector valve, play the effect of opening or closing, there is following shortcoming in existing air reversing valve: poor sealing performance mostly, high temperature resistant erosion resistibility is poor, complex structure, Safety performance is low, and user cost is high, commutation number of times can not meet the demands, and is unfavorable for extensively promoting the use of.
Model utility content
For the deficiency that prior art exists, the utility model provides a kind of high temperature resistant, antiscour, soft seal and the air reversing valve of long service life.
The utility model is achieved through the following technical solutions:
A kind of high temperature resistance antiscour soft seal air reversing valve, comprise cylinder, housing, bulb link rod and valve plate, the floor installation of described cylinder has air cylinder support, the top of described housing is by hexagon socket head cap screw fixed guide cover, described guide sleeve is fixed on guide holder by packing gland, the bottom of described housing is provided with bottom bracket, described bulb link rod is fixedly connected with bulb base by bulb gland, one end of described bulb link rod is fixedly connected with bulb base by bulb gland, the other end is connected with the piston shaft of described cylinder by the top of described housing, described bulb base is connected with described valve plate, the bottom of described valve plate is provided with seal ring, described seal ring is fixed on seal ring base by seal ring pressing plate.
Further, described seal ring is set to O type elevated-temperature seal cushion rubber.
Further, described bulb link rod is connected by the piston shaft of connecting rod with described cylinder.
Compared with prior art, the beneficial effects of the utility model are:
1, seal ring of the present utility model is set to O type refractory seal cushion rubber, not only increases sealing of the present utility model, enhances the ability of antiscour, reduce the probability of gas leakage; And heat resistance is strong, can be high temperature resistant 600 degree, greatly extend working life of the present utility model;
2, cylinder of the present utility model is by connecting rod and bulb link rod compounding practice, achieves full automatic working, does not need artificial execution, improve Safety performance, reduce user cost;
3, cylinder of the present utility model can ensure the commutation number of times of equipment and stable, reliable;
4, the utility model structure is simple, easy to use, is beneficial to and extensively promotes the use of.
Accompanying drawing explanation
Accompanying drawing is overall structure sectional view of the present utility model.
In accompanying drawing: 1. cylinder; 2. air cylinder support; 3. housing; 4. bottom bracket; 5. packing gland; 6. guide sleeve; 7. hexagon socket head cap screw; 8. guide holder; 9. connecting rod; 10. bulb link rod; 11. bulb glands; 12. bulb bases; 13. valve plates; 14. seal ring pressing plates; 15. seal ring bases; 16. seal rings.
Embodiment
A kind of high temperature resistance antiscour soft seal air reversing valve, comprise cylinder 1, housing 3, bulb link rod 10 and valve plate 13, the floor installation of cylinder 1 has air cylinder support 2, the top of housing 3 is by hexagon socket head cap screw 7 fixed guide cover 6, guide sleeve 6 is fixed on guide holder 8 by packing gland 5, the bottom of housing 3 is provided with bottom bracket 4, one end of bulb link rod 10 is fixedly connected with bulb base 12 by bulb gland 11, the other end is connected with the piston shaft of cylinder 1 by the top of housing 3, bulb base 12 is connected with valve plate 13, the bottom of valve plate 13 is provided with seal ring 16, seal ring 16 is fixed on seal ring base 15 by seal ring pressing plate 14.
Further, seal ring 16 is set to O type elevated-temperature seal cushion rubber.
Further, bulb link rod 10 is connected with the piston shaft of cylinder 1 by connecting rod 9.
Air reversing valve is made up of the same valve body of two structures and bottom bracket, and the valve plate according to difference two valve bodies of temperature is alternately closed and opens, and temperature needs to arrange according to actual environment.Specific works principle: when needs cut off source of the gas, cylinder control link drives bulb link rod to move downward, and valve plate moves downward thereupon, due to the effect of seal ring, valve plate is fitted on valve opening platform, reaches the effect cutting off source of the gas, when source of the gas opened by needs, operating process is contrary to the above.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
