Abstract
The invention relates to a high-temperature wear-resistant sealing device for a movable pipeline, in particular to a mechanical sealing device suitable for a pipeline with a rough surface or low surface processing precision in a high temperature (200 DEG C to 800 DEG C) state during reciprocating motion. The device comprises a fixed sealing flange 1, a movable sealing flange 2, a movable sealing flange 3, a graphite sealing ring 4, a movable pipeline 5, a movable pipeline through plate 6 and a connecting bolt 7. The device is low in surface processing precision for the pipeline, particularly a long and large pipeline without surface processing conditions; the high-temperature wear-resistant sealing device for the movable pipeline is in a highly sealed state, no dust or deposited slag flies upward during the blowing process, and no secondary environmental pollution exists; the device is resistant to high temperature and wear-resistant, long in service life and low in maintenance cost.
Description
Technical field
The present invention relates to a kind of floating pipe high-temperature wearable seal arrangement, the mechanical seal while being applicable to reciprocal movable under high temperature (200 DEG C-800 DEG C) state of pipeline that rough surface or surface Machining precision are low.
Background technique
In high temperature strength scarfing cinder purging field, extensively exist and compressed air line or fan airflow pipeline need to be stretched into blowing deposited dust in container, accumulated slag, as boiler scarfing cinder, heat treatment furnace deashing, but cause the dust stratification of cleaning, accumulated slag from pipeline gap, to fly upward because sealing effect is poor, cause secondary pollution, work on the spot environment is poor.
Summary of the invention
The object of the invention is to for the defect of existing Purge methods provide a kind of can make in high temperature strength scarfing cinder purging field stretching in container blowing deposited dust, accumulated slag for the compressed air line that ventilates or fan airflow pipeline time, good sealing effect, can not cause the floating pipe high-temperature wearable seal arrangement of secondary pollution.
For achieving the above object, the technical solution used in the present invention is: the present invention relates to a kind of floating pipe high-temperature wearable seal arrangement, sealing while being applicable to reciprocal movable under the condition of high temperature of pipeline that rough surface or surface Machining precision are low, device comprises fixing seal flange 1, movable sealing flange 2, movable sealing flange 3, graphite-seal ring 4, floating pipe 5, floating pipe is by plate 6, connecting bolt 7, fixing seal flange 1, movable sealing flange 2, movable sealing flange 3, graphite-seal ring 4, floating pipe forms seal arrangement by plate 6, floating pipe 5 is the flexible linear reciprocating motion that does from sealing configuration.The groove that has filling graphite-seal ring 5 on described fixing seal flange 1, in movable sealing flange 2, movable sealing flange 3 are sleeved on, is connected and fixed by plate 6 by bolt and floating pipe.Described movable sealing flange 2 is sleeved in fixing seal flange 1, forms the active part of sealing configuration together with movable sealing flange 3.Described movable sealing flange 3 is sleeved in fixing seal flange 1, forms the active part of sealing configuration together with movable sealing flange 2.Described floating pipe, by there being the groove of filling graphite-seal ring 5 on plate 6, in movable sealing flange 2, movable sealing flange 3 are sleeved on, is connected and fixed by connecting bolt 7 and fixing seal flange 1.Described graphite-seal ring 4 is the support seal rings with keel structure.
[0005] advantage of the present invention is:
1, low to the surface Machining required precision of pipeline, especially do not possess the pipeline of growing up of surface Machining condition;
2, floating pipe high-temperature wearable seal arrangement, in high-seal state, does not have dust or accumulated slag to fly upward in purge, does not cause secondary environmental pollution;
3, floating pipe high-temperature wearable sealing heat resistant and wear resistant, long service life, maintenance expenses is low.
brief description of the drawingsfig. 1 is the structural drawing of floating pipe high-temperature wearable seal arrangement.

embodiment explanation
tell about the seal action principle of floating pipe high-temperature wearable seal arrangement below in conjunction with Fig. 1:
Device comprises that fixing seal flange 1, movable sealing flange 2, movable sealing flange 3, graphite-seal ring 4, floating pipe 5, floating pipe are by plate 6, and fixing seal flange 1, movable sealing flange 2, movable sealing flange 3, graphite-seal ring 4, floating pipe are by plate 6.First movable sealing flange 2, movable sealing flange 3 are sleeved in fixing seal flange 1, are connected and fixed by plate 6 by connecting bolt 7 and floating pipe.Again floating pipe 5 is passed through to plate 6 and fixing seal flange 1 through floating pipe, now movable sealing flange 2, movable sealing flange 3 is also set with on floating pipe.Floating pipe is the flexible linear reciprocating motion that does in sealing configuration.Floating pipe is by loading the primary seal of graphite-seal ring 5 as floating pipe on plate 6 and fixing seal flange 1, movable sealing flange 2 and movable sealing flange 3 do secondary seal, for regulating the local gap causing due to the disalignment of pipeline, reach sealing purpose.
