Height, slide plate are easily deformed, and the gap after slide plate deformation between two pieces of slide plates becomes uneven, and some places gap has been even more than close
The diameter of graphite bar is sealed, the cold draining air into system is so begun to, causes boiler efficiency to decline.Cold sky is revealed to internal system
Another reason for gas is exactly the non-perpendicular displacement for moving up and down also other directions of burner hearth thermal walking, this is also to cause two pieces of cunnings
The hot gap of plate, which changes, causes the major reason that cold air is revealed into system,.
Utility model content
The utility model has thermal walking slide plate to solve boiler smoking mouth in the prior art and high temperature boiler flue gas tube junction
It is easily deformed, the gap between two pieces of slide plates becomes uneven, easily the cold draining air into system, causes asking for boiler efficiency decline
Topic, and then provide a kind of for boiler smoking mouth and the seal assembly of high temperature boiler flue gas tube junction.
The utility model is for the technical solution used that solves the above problems：
It is solid that it includes puller bolt, spring base, spring, slide bar, outer sleeve body, stent, angle bar, two caging bolts and two
Determine bolt；Outer sleeve body is circular staving, and puller bolt is arranged on the bucket bottom of outer sleeve body, and spring base is arranged on overcoat close to bucket bottom
In vivo, the end of thread of puller bolt is connected with spring base, and slide bar is arranged in the openend of outer sleeve body, between spring base and slide bar
Equipped with spring, slide bar is machined with strip through-hole along its length, and two caging bolts are oppositely arranged on the outer of stent and outer sleeve body
On side wall, and the end of thread of each caging bolt is arranged in the strip through-hole of slide bar, and two, the other end and the angle bar of slide bar is straight
It is fixedly connected, is squeezed on the inside of two straight panels of angle bar on graphite packing, stent is installed by two fixing bolts on the outside of plate
On slide plate.
The beneficial effects of the utility model are：
The utility model boiler smoking mouth and high temperature boiler flue gas tube junction by seal assembly extruded anisotropic graphite packing 11 and then
Reach the effect of sealing, can prevent the phenomenon of the cold draining air into system from occurring by the sealing of graphite packing 11, ensure boiler
Normal operation, improve the work efficiency of boiler, work efficiency improves 5%-10%.Outer sleeve body 6 can be around two caging bolts 9
Rotated freely, ensure that compression effect of the angle bar 10 to graphite packing 11, improve airtight quality.
