Description
Technical field
The utility model belongs to a kind of sealing device, and in particular to a kind of flue damper plate valve.
Background technique
In electric power, metallurgy, petrochemical industry etc., need to use the valve of a large amount of all styles of, valve produces enterprise
Play the role of vital.In boiler flue, cleaning shaft, slide valve is mostly used greatly, in the prior art the valve of slide valve
Bar is connected by screw bolts mostly with frame, and leakage, once getting rusty, will cause valve in outdoor cruelly mostly for boiler flue, cleaning shaft
Switch motion is hard or valve switch movement is not in place, once corrosion is serious, also will cause lead screw and falls off with spool, cause valve
Door is scrapped.In addition, the reason of influencing slide valve service life at present is greatly the sealing because between flashboard and valve body
Face is also easy to produce scratch, and the valve, which is scrapped, after its leakproofness does not reach requirement after a period of use to use.Worked
Because slide valve is not closed completely in journey, leakproofness is not high, easily leakage pernicious gas, causes the pollution of environment, ecology, is producing and is tieing up
Life can be generated safely during shield dangerous.
Utility model content
The utility model is proposed to overcome disadvantage existing in the prior art, and the purpose is to provide a kind of flue
Slide valve.
The technical solution of the utility model is:
A kind of flue damper plate valve, including the Rotary grate support and flashboard case connected by bolt assembly, driving mechanism with
The connection of Rotary grate support, core pipe are set in flashboard case, and drive axis connection with driving mechanism；Core pipe is connected by bolt assembly
It takes in succession；Connecting tube lower end passes through flashboard lid, and connect with flashboard；Flashboard lid is connect with flashboard top surface；The setting of flashboard bottom
Center bridge, stack base are arranged footstock, form centering chamfer at the top of footstock；The flashboard lid is semicircle ring structure, flashboard top
Face is semicircle cambered surface.
Flashboard bottom face both ends are fixed in wall by foundation bolt.
The core pipe is set to immediately below Rotary grate support.
The internal diameter of the flashboard lid is matched with the outer diameter of flashboard top surface.
The centering chamfer, center bridge, flashboard lid, flashboard, core pipe and connecting tube coaxial line.
The centering chamfer and center bridge clearance fit.
The beneficial effects of the utility model are:
The utility model provides a kind of flue damper plate valve, designs simple, structurally reasonable, easy to use；Footstock and fixed
The design of heart block guarantees slide valve stable position；Guarantee that the leakproofness between flue damper plate valve and flue, long service life are prevented
Stopping leak dew, guarantees the safety of production.

Case 2, driving mechanism 3 are connect with Rotary grate support 1, and core pipe 4 is set in flashboard case 2, and are connected with 3 drive shaft of driving mechanism
It connects；Core pipe 4 connects connecting tube 5 by bolt assembly；5 lower end of connecting tube passes through flashboard lid 7, and connect with flashboard 8；Flashboard lid 7
It is connect with 8 top surface of flashboard；Center bridge 9 is arranged in 8 bottom of flashboard, and footstock 10 is arranged in stack base, and it is fixed to be formed at the top of footstock 10
Heart slot；The flashboard lid 7 is semicircle ring structure, and 8 top surface of flashboard is semicircle cambered surface.
The 2 bottom surface both ends of flashboard case are fixed in wall by foundation bolt 6.
The core pipe 3 is set to immediately below Rotary grate support 1.
The internal diameter of the flashboard lid 7 is matched with the outer diameter of 8 top surface of flashboard.
The centering chamfer 11, center bridge 9, flashboard lid 7,5 coaxial line of flashboard 8, core pipe 4 and connecting tube.
The centering chamfer 11 and 9 clearance fit of center bridge.
The utility model provides a kind of flue damper plate valve, designs simple, structurally reasonable, easy to use；Footstock and fixed
The design of heart block guarantees slide valve stable position；Guarantee that the leakproofness between flue damper plate valve and flue, long service life are prevented
Stopping leak dew, guarantees the safety of production.
