Abstract
The invention relates to a sleeve-supporting room-temperature wear-resisting sealing device which is fit for the mechanical seal during a reciprocating interaction process under room temperature (at -50 DEG C to 200 DEG C) while a sleeve by a double-layer pipeline with rough surface or low surface processing precision is formed. The device comprises a sealing base 1, a sealing slot 2, a sealing slot 3, a supporting sealing ring slot 4, a fluororubber sealing ring 5, a moveable tube 6, a fixing pipe 7, and a supporting sealing ring 8. The sleeve-supporting room-temperature wear-resisting sealing device has low demand on the surface processing precision of the pipeline, especially, the long big pipeline which does not meet the surface processing condition; the environmental secondary pollution is avoided; the compressed air is kept or the airflow leakage of the fan is reduced to the minimum; the sleeve-supporting room-temperature wear-resisting sealing device can ensure the slag-removing and dust-removing effect; the supporting sealing ring is arranged, so that the pipeline is prevented from being eccentrically abraded by force during a running process; the device is room-temperature resisting and wear-resisting, long in service life and low in maintenance cost.
Description
Technical field
The present invention relates to a kind of collar supports normal temperature head wear-resistant sealing device, mechanical seal during reciprocal interactive when being applicable to the low double-skin duct of rough surface or surface Machining precision and forming sleeve pipe under normal temperature (50 ℃-200 ℃) state.
Background technique
In normal 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.Because duct length is subject to the impact of deashing, scarfing cinder distance, when deashing, scarfing cinder are distant, be subject to the impact in place to need to change single pipe into bilayer sleeve, to meet stroke needs.The poor dust stratification of cleaning, the accumulated slag of causing of sealing effect between bilayer sleeve can fly upward from pipeline gap, causes secondary pollution, and work on the spot environment is poor; Cause pressurized air or fan airflow to sew simultaneously, reduce scarfing cinder ash-removal effect.
Summary of the invention
The object of the invention is to defect for existing Purge methods provide a kind of can make in normal temperature strength scarfing cinder purging field for the compressed air line that ventilates or fan airflow pipeline, stretching in container blowing deposited dust, accumulated slag time, good sealing effect, can not cause secondary pollution, can keep again pressurized air or fan airflow to sew and be reduced to minimum degree, guarantee the collar supports normal temperature head wear-resistant sealing device of scarfing cinder ash-removal effect simultaneously.
For achieving the above object, the technical solution used in the present invention is: the present invention relates to a kind of collar supports seal ring normal temperature head wear-resistant sealing device, sealing while being applicable to reciprocal movable under normal temperature state of sleeve pipe that rough surface or surface Machining precision are low, device comprises sealing pedestal 1, seal groove 2, seal groove 3, support closure gasket groove 4, viton seal ring 5, adjustable pipe 6, fixed tube 7, support seal ring 8, sealing pedestal 1, seal groove 2, seal groove 3, support closure gasket groove 4, viton seal ring 5, support seal ring 8 and form seal arrangement, seal arrangement is arranged on the afterbody of adjustable pipe 6, adjustable pipe 6 and fixed tube 7 form sleeve pipe, adjustable pipe 6 is done linear reciprocating motion on fixed sleeving 7.Seal groove 2, seal groove 3, support closure gasket groove 4 on described sealing pedestal 1.In described seal groove 2, seal groove 3, viton seal ring 5 is installed respectively.In described support closure gasket groove 4, be installed with and support seal ring 8.Described viton seal ring 5 is the support seal rings with keel structure.The material of described support seal ring 8 is to have flexible high-intensity material, can be nylon or Steel Spring Plate.
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, collar supports normal temperature head wear-resistant sealing device, in high-seal state, does not have dust or accumulated slag to fly upward in purge, does not cause secondary environmental pollution;
3, can keep pressurized air or fan airflow to sew and be reduced to minimum degree, guarantee the collar supports normal temperature head wear-resistant sealing device of scarfing cinder ash-removal effect;
4, collar supports normal temperature head wear-resistant sealing device, owing to there being support seal ring, can be avoided stressed eccentric wear in conduit running, and resistance to normal temperature is wear-resisting, long service life, and maintenance expenses is low.
accompanying drawing explanationfig. 1 is the structural drawing of collar supports normal temperature head wear-resistant sealing device.
1---sealing pedestal 2---seal groove 3---seal groove 4---support closure gasket groove 5---viton seal ring 6---adjustable pipe 7---fixed tube 8---support seal ring
[0007] embodiment explanation
below in conjunction with Fig. 1, tell about the seal action principle of collar supports normal temperature head wear-resistant sealing device:
Device comprises sealing pedestal 1, seal groove 2, seal groove 3, support closure gasket groove 4, viton seal ring 5, adjustable pipe 6, fixed tube 7, supports seal ring 8, seals pedestal 1, seal groove 2, seal groove 3, supports closure gasket groove 4, viton seal ring 5, supports seal ring 8 composition seal arrangements.First viton seal ring 5 is arranged on respectively in seal groove 2, seal groove 3, again support seal ring 8 is arranged on and supports in closure gasket groove 4, to with upper sealing device, be welded on the afterbody of adjustable pipe 6, then adjustable pipe 6 is sleeved in fixed tube 7 together with sealing pedestal 1, seal groove 2, seal groove 3, support closure gasket groove 4, viton seal ring 5, adjustable pipe 6, support seal ring 8.Adjustable pipe 6 is the flexible linear reciprocating motion of doing in sealing configuration.Viton seal ring 5 on seal 1 is as the primary seal of adjustable pipe, supported seal ring 8 and the secondary seal of doing alive, the local gap causing for the disalignment regulating due to pipeline is guaranteed not produce the eccentric wear occurring due to stressed operation simultaneously, reaches sealing purpose.
