Description
Technical field
The utility model relates to technical field of pipeline connection, specifically, it is flexible to be related to a kind of pipeline with check function
Device.
Background technique
In modern industry, the pipe-line system that pipeline is constituted is more and more huger, and application field is also more and more extensive.Pipeline is stretched
Contracting device is the connection attachment recompensed in pipeline connection due to change in size caused by expanding with heat and contract with cold, and avoids pipeline cold because of heat expansion
Compression deformation fracture, protective conduit.Pipe line check valve is the valve mechanism for preventing liquid reflux in pipeline, and structure or performance are undesirable
Often there is the phenomenon that a small amount of liquid reflux in use in check-valves, and brings security risk for the application of pipe-line system.
In large-scale pipeline engineering project, needs to repeat that a large amount of pipeline telescopic device and pipe line check valve are installed, waste
A large amount of human and material resources and time.
Utility model content
The purpose of this utility model is to provide a kind of pipeline telescopic device with check function, is asked with the technology for solving above-mentioned
Topic.
To solve the above problems, the technical scheme adopted by the utility model is
A kind of pipeline telescopic device with check function, including rubber expansion adapter, the lower part of the rubber expansion adapter are set
There is lower flange, top is equipped with upper flange plate；Steel ball is equipped with inside the rubber expansion adapter；The upper flange plate top is logical
It crosses and has been bolted pipe flange, bar support frame is equipped at the internal orifice of the upper pipe flange, the bar support frame
Bottom is equipped with bar, and the bar end extends to inside the rubber expansion adapter, the top of steel ball.
Preferred: the bar support frame crosses the center of the upper pipe flange internal orifice, and the bar is arranged described
At the center of upper pipe flange internal orifice.
It is preferred: it is close that the arc-shaped fitted closely with steel spherical cambered surface is equipped at the rubber expansion adapter inner surface nozzle
Cover.
The utility model has the advantages that compared with prior art, the pipeline telescopic device described in the utility model with check function have with
Lower advantage:
1, save pipeline installation cost: the structure becomes one two parts of expansion bend and check-valves, only needs primary
Installation can play a dual role of that pipeline is flexible and non-return saves big buret in the large-scale pipeline engineering project of complexity
Road mounting material, expense cost and the manpower of engineering construction, time cost.
2, structure design safety is reliable, good airproof performance: having steel ball, rubber face in the rubber expansion adapter of the utility model
Flexible elasticity, sealing surface keep sealing surface and steel spherical cambered surface close in arc-shaped using the own form and weight of steel ball
Fitting, so that medium cannot flow back, plays the role of non-return.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；
In figure: → indicate medium flow direction；
Fig. 2 is a kind of overlooking structure diagram of embodiment of the utility model；
Fig. 3 is a kind of present invention looks up structural representation of embodiment of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description
Embodiment:
Referring to figs. 1 to Fig. 3, the pipeline telescopic device with check function described in the present embodiment, including rubber expansion adapter 4,
Steel ball 5 is equipped with inside the rubber expansion adapter 4；It is equipped with and 5 arc of steel ball at the 4 inner surface nozzle of rubber expansion adapter
The arc-shaped sealing surface that face fits closely.
The lower part of the rubber expansion adapter 4 is equipped with lower flange 6, and top is equipped with upper flange plate 7.Wherein:
7 top of upper flange plate is connected with pipe flange 1 by bolt 2, sets at the internal orifice of the upper pipe flange 1
There are the bar support frame 8 for crossing the 1 internal orifice center of upper pipe flange, the bottom of the bar support frame 8, upper pipe flange 1
Bar 3 is equipped at the center of internal orifice, 3 end of bar extends to inside the rubber expansion adapter 4, the top of steel ball 5.
Before rubber expansion adapter 4 does not bind round upper and lower ring flange 6,7 when assembly, in 4 mouthfuls of indentation steel balls of rubber expansion adapter
5 (because rubber expansion adapter 4 is flexible)；It is then charged into upper and lower ring flange 6,7 and upper pipe flange 1,4 liang of rubber expansion adapter
The upper and lower ring flange 6,7 at end passes through the connection locking of bolt 2 with pipe flange respectively.
The utility model must pass through fluid pressure from bottom when media flow by right angle setting up and down in pipeline construction
Power washes steel ball 5 open, and then steel ball 5 is made steel ball 5 be unlikely to blocking medium and go out on top by the interception of bar 3
Mouthful, medium passes through the gap of 8 surrounding of bar support frame, continues to flow to terminal.When medium back flow, work of the steel ball 5 in gravity
It is sunk down under at the nozzle of rubber expansion adapter 4, cambered surface is fitted closely with arc-shaped sealing surface, blocks nozzle, makes medium
It cannot flow back.
Because the internal orifice of upper and lower ring flange 6,7 wales the throat of rubber expansion adapter 4, steel ball 5 will not be squeezed because pressure is excessive
In inlet pipe road.
The utility model becomes one two parts of expansion bend and check-valves, in complicated large-scale pipeline engineering project
In, save manpower, the time cost of a large amount of pipeline mounting materials, expense cost and engineering construction.The utility model has knot
The advantages that structure design safety is reliable, good airproof performance, facilitates construction, saves pipeline installation cost.
The above is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all benefits
The equivalent structure made by the utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain, similarly within the scope of patent protection of the utility model.
