Description
Technical field
The utility model is related to gas pipeline sealed fixing device, especially a kind of gas pipeline leak source sealing device.
Background technology
In the laying of gas pipeline, especially in the laying of some industrial enterprise's gas pipelines, as smelting enterprise adopts
Gas piping, since its part of the influence of external environment is susceptible to corrosion and damage, generates leak source after longtime running.
Two ways is generally used for the repair of leak source at present, one is entirety production circuit is stopped production, closes and fires
The valve of feed channel connection contacts corresponding construction unit and is cut to leak source position again later, purging, then welding conducting again；Its
Second is that being filled up using fluid sealant to leak source position during conduit running.
But there are some problems in above two mode, when using first way, need to integrally stop production in use,
The loss of operating cost caused by each stopping process is very big, in particular for some large-scale production units, stops production
Caused loss is often difficult to count；And the second way is used, due to being the presence of flowing in filling, in pipeline
Combustion gas, and the pressure that leak source position is leaked is larger, therefore, it is difficult to ensure that it secondary will not be revealed after filling up, exist compared with
Big security risk.
Utility model content
It the purpose of the utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable for structure, effectively fills up leak source,
Prevent a kind of secondary gas pipeline leak source sealing device to leak.
The technical scheme adopted by the utility model is that：
A kind of gas pipeline leak source sealing device, the filling with sealant in the leak source, it is characterised in that：In pipeline leakage point
The gasket that the outer side covering one of position is made using elastic material, the gasket is inlaid in a sealing snap-gauge, backwards
One fixing chuck plate is installed on the outside of the pipeline of leak source position, a groove is made in the middle part of the fixing chuck plate, groove internal pressure fastening
Surely there is the end face outside of pipeline, the fixing chuck plate and the both side ends for sealing snap-gauge are symmetrical arranged makes an extension board respectively,
Bolt is coated in two extension boards of homonymy, the end of the bolt is fixed by nut check.
Moreover, the groove location of the fixing chuck plate made along the axial direction uniform intervals of pipeline it is multiple convex stupefied, each
Convex stupefied end is closely crimped with the end face outside of pipeline.
It is adopted moreover, clamping to be fixed between the end face for the extension board homonymy that the fixing chuck plate and sealing snap-gauge both sides are made
The briquetting made with elastic material.
The advantages of the utility model and good effect are：
In the utility model, fluid sealant fills up leak source position, and the gasket that outside is arranged will then fill up sealing
Leak source position after glue is completely covered, and the pressure of ecto-entad is on the one hand provided for fluid sealant, effectively prevent fluid sealant in gas
High pressure effect it is lower occur it is secondary leak, even if on the other hand after the secondary leakage of fluid sealant, still can guarantee that leak source position is
Sealing, it is effectively prevent leaking for combustion gas, snap-gauge is sealed and fixing chuck plate is matched and is locked by screw bolt and nut, ensure
Gasket and the pipeline end face of leak source position are compressed；Convex stupefied setting makes fixing chuck plate be connect for point with pipeline end face outside
It touches, by the way of being contacted using face, force is more uniformly distributed, and is not easy to loosen, and can effectively prevent the sealing of sealing pad position
It is not tight, increase safety；Fixed briquetting between the extension board that fixing chuck plate and sealing snap-gauge both sides are made can pass through its compression
Amounts of thickness variation required to determine whether coupling mechanism force that bolts and nuts provide reaches the force for compressing gasket.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
With reference to embodiment, following embodiments, which are illustrative, are not limited is further illustrated to the utility model
, the scope of protection of the utility model cannot be limited with following embodiments.
A kind of gas pipeline leak source sealing device, the filling with sealant 9 in the leak source 8 of pipeline 10, the wound of the utility model
Newly it is, the gasket 7 that the outer side covering one in pipeline leakage point position is made using elastic material, the gasket is inlaid in one
It seals in snap-gauge 11, a fixing chuck plate 2 is installed on the outside of the pipeline backwards to leak source position, one is made in the middle part of the fixing chuck plate
Groove, is compressed with the end face outside of pipeline in the groove, and the both side ends of the fixing chuck plate and sealing snap-gauge are symmetrically set
It sets and makes an extension board respectively, bolt 5 is coated in two extension boards of homonymy, the nuts 1 of the bolt is installed on fixing card
In plate, the end of the bolt protrudes through nut 6 by sealing snap-gauge and is locked.
In the present embodiment, the groove location of the fixing chuck plate is made multiple convex stupefied along the axial direction uniform intervals of pipeline
3, each convex stupefied end is closely crimped with the end face outside of pipeline.
It is clamped in the present embodiment, between the fixing chuck plate and the end face for sealing the extension board homonymy that snap-gauge both sides are made solid
Surely there is the briquetting 4 made using elastic material.
In the present embodiment, the materials such as rubber or silica gel can be used in elastic material.
The course of work of the utility model is：
When the utility model is used, it is filled up first using fluid sealant in leak source position, later on the outside of fluid sealant
Pipeline location coats a gasket, and the gasket using bolt after sealing snap-gauge and fixing chuck plate compression by tightening fixation, directly
It is screwed to the preset compressed thickness of briquetting to bolt and sealing can be completed.
In the utility model, fluid sealant fills up leak source position, and the gasket that outside is arranged will then fill up sealing
Leak source position after glue is completely covered, and the pressure of ecto-entad is on the one hand provided for fluid sealant, effectively prevent fluid sealant in gas
High pressure effect it is lower occur it is secondary leak, even if on the other hand after the secondary leakage of fluid sealant, still can guarantee that leak source position is
Sealing, it is effectively prevent leaking for combustion gas, snap-gauge is sealed and fixing chuck plate is matched and is locked by screw bolt and nut, ensure
Gasket and the pipeline end face of leak source position are compressed；Convex stupefied setting makes fixing chuck plate be connect for point with pipeline end face outside
It touches, by the way of being contacted using face, force is more uniformly distributed, and is not easy to loosen, and can effectively prevent the sealing of sealing pad position
It is not tight, increase safety；Fixed briquetting between the extension board that fixing chuck plate and sealing snap-gauge both sides are made can pass through its compression
Amounts of thickness variation required to determine whether coupling mechanism force that bolts and nuts provide reaches the force for compressing gasket.
