Description
Technical field
The invention belongs to technical field of pipeline connection, and in particular to a kind of pipe flange separating tool.
Background technology
Pipeline is usually utilized to oil or natural gas from a local transport to another place.Pipeline is usually by multiple
Pipeline forms, and there is flange at the both ends of each pipeline, other pipelines are connected to facilitate.Multiple fasteners can generally be used
One pipe flange is fixed on another pipe flange by (such as bolt).
In many cases it is required corresponding pipe flange is detached, to facilitate the maintenance of pipeline and replacement.It is but traditional
Flange separating tool often volume is big, it is expensive, operate relative difficulty.
Invention content
The problem of present invention is big for existing pipe flange separating tool physical examination, and price is high, operating difficulties, provides a kind of pipe
Road flange separating tool.
The present invention adopts the following technical scheme that：
A kind of pipe flange separating tool includes the voussoir of a pair of of wedge shape, before each voussoir respectively includes the first front surface, second
Surface, first side, second side and top surface, first front surface and the second front surface form tapering point, and tapering point is located at
Relative to the side of top surface between first side and second side, the first side and second side of each voussoir are relative to taper
The side at end is equipped with perforation, and tapering point is located between two pipe flanges, with separate pipeline flange, is equipped with to connect in perforation
The fixation band of two voussoirs, fixed band and perforated interval cooperation, anchor band are wound on pipeline one week.
The fixed band is made of rubber or polyurethane, and tensile strength >=1.4MPa of band is fixed made of rubber.Poly- ammonia
Tensile strength >=1.5MPa of band is fixed made of ester.
One end of the fixation band is equipped with retainer ring, and the other end is equipped with lock.
The voussoir is made of aluminium-bronze-copper alloy or carbon steel.
The rectangular cross-section of first front surface and the second front surface.
The section of the first side and second side is triangle.
The rectangular cross-section of the top surface.
Beneficial effects of the present invention are as follows：
1. the present invention is applicable in various pipe flanges, applied widely.
2. the configuration of the present invention is simple, easy to use.
3. the present invention improves the safety of construction.

Specific embodiment
With reference to attached drawing, the present invention will be further described.
A kind of pipe flange separating tool, includes the voussoir of a pair of of wedge shape, each voussoir respectively include the first front surface 1,
Second front surface 2, first side 3, second side 4 and top surface 5,1 and second front surface 2 of the first front surface form taper
End, tapering point is between first side 3 and second side 4 relative to the side of top surface 5,3 He of first side of each voussoir
Second side 4 is equipped with perforation 6 relative to the side of tapering point, and tapering point is located between two pipe flanges, with separating pipe Dow process
Orchid, is equipped with the fixation band 7 for connecting two voussoirs, 6 clearance fits of fixed band 7 and perforation in perforation 6, fixed band 7 is looped around
Pipeline one week.
The fixed band 7 is made of rubber or polyurethane, and tensile strength >=1.4MPa of band 7 is fixed made of rubber.It is poly-
Tensile strength >=1.5MPa of band 7 is fixed made of urethane.
One end of the fixed band 7 is equipped with retainer ring 8, and the other end is equipped with lock 9.
Retainer ring 8 and lock 9 are fixed on the both ends of fixed band 7 by snap ring 10 respectively, can prevent the cunning of fixed band 7
It is dynamic.
The voussoir is made of aluminium-bronze-copper alloy or carbon steel.
Spark will not be generated in collision using aluminium-voussoir made of bronze-copper alloy, therefore, deposited suitable for pipeline
Put the unsafe conditions of flammable liquid, gas and dirt residue.
Using voussoir made of carbon steel, applied in the metal structure of compact structure, the first voussoir and the second wedge can be resisted
The deformation force that block generates, places it between the pipe flange for conveying not dangerous material, has very high non-deformability, warp
It is durable long.
The rectangular cross-section of first front surface, 1 and second front surface 2.
The section of the first side 3 and second side 4 is triangle.
The rectangular cross-section of the top surface 5.
The application process of the present invention includes the following steps：
1. remove the clamp device between two pipe flanges；
2. by the tapered end of the first voussoir and the second voussoir relatively after, respectively be inserted into two pipe flanges between；
3. fixed band 7 is passed through perforation 6, it is looped around pipeline；
4. pulling fixed band 7, the first voussoir and the second voussoir are fastened；
5. by 9 connection of retainer ring 8 and lock；
6. external force is applied to the first voussoir and the second voussoir by hammer or other tools, you can detach pipe flange.
