Description
Technical field
It the utility model is related to a kind of by-passing valve, especially a kind of by-passing valve for rotary kiln afterbody.
Background technology
With the more strict implement of Environment Protection Policy, it is desirable to which lime kiln dust discharge must be up to standard, controls in 30mg/
m3Below.The former design of rotary kiln by-passing valve due to no sealing ring, cause iron iron is caused tightness decline make dust from
Exhaust outlet, which is emerged, causes concentration of emission exceeded, and environment is contaminated.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of good kiln tail bypass of sealing effect
Valve.
The technical solution adopted in the utility model is：A kind of kiln tail by-passing valve, including valve body, on the body top is set
Sealing cover；Valve rod is provided with the middle part of the valve body, valve rod connects sealing plate after top cover labyrinth and lower sealing cover；The valve rod
Upper end be connected with driving device, valve rod is under driving device effect by lifting opening for lower sealing cover and sealing plate application valve body
Close；The valve rod sets sealing ring one to seal with lower sealing cover junction；The body base is provided with firm banking；It is described solid
Determine base to fix on a passage；
Further, gasket one and gasket two are provided with the firm banking；The gasket one and lower sealing
Lid size matches；The gasket two matches with sealing board size；
Further, the valve body is arranged at the offgas outlet of rotary kiln afterbody；
Further, the driving device is cylinder, and is provided with locking device of dying；
Further, the top cover labyrinth is sealed firmly using steel plate with passage；The steel plate sets close with valve rod junction
Seal two seals.
The beneficial effects of the utility model are：It is simple in structure, operate easy to maintenance, applicable hot environment, service life
It is long, by the lifting of cylinder drive control valve rod, realize the opening and closing of by-passing valve；Increase sealing ring, soft seal and hard sealing are tied
Close, multi-sealed raising tightness, ensure that the discharge of exhaust outlet is dense up to standard.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1. driving device, 2. top cover labyrinths, 3. valve rods, 4. sealing rings one, 5. lower sealing covers, 6. sealing plates, 7. are consolidated
Determine base, 8. gaskets one, 9. gaskets two, 10. passages, 11. steel plates, 12. sealing rings two.
Embodiment
It is further to the utility model below in conjunction with the accompanying drawings in order to be more clearly understood that the technical solution of the utility model
Explanation.
A kind of kiln tail by-passing valve as shown in Figure 1, including valve body, it is described at the offgas outlet of rotary kiln afterbody
Body top sets top cover labyrinth 2, and top cover labyrinth 2 is sealed firmly using steel plate 11 with passage 10, and steel plate 11 and 3 junction of valve rod
Sealing ring 2 12 is set, is combined using hard sealing and soft seal two ways, ensures leakproofness；
Valve rod 3 is provided with the middle part of the valve body, valve rod 3 connects sealing plate 6 after top cover labyrinth 2 and lower sealing cover 5；Institute
The upper end for stating valve rod 3 is connected with driving device 1, and driving device 1 fills for cylinder and equipped with locking device of dying, valve rod 3 in driving
Put the opening and closing by lifting 6 application valve body of lower sealing cover 5 and sealing plate under 1 effect；The valve rod 3 and 5 junction of lower sealing cover
Sealing ring 1 is set to seal；
The body base is provided with firm banking 7, and firm banking 7 is fixed on passage 10, is provided with gasket
One 8 and gasket 29；The gasket 1 matches with 5 size of lower sealing cover；The gasket 29 and 6 size of sealing plate
Match.
The utility model is simple in structure, operates easy to maintenance, applicable hot environment, service life length, is driven by cylinder
The lifting of dynamic control valve rod, realizes the opening and closing of by-passing valve；Increase sealing ring, soft seal and hard sealing are combined, it is multi-sealed to carry
High sealed, ensure that the discharge of exhaust outlet is dense up to standard.
The above is only the better embodiment of the utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
