Description
Technical field
The invention belongs to environmental protection equipment sealing for tubing joints technical field in the metallurgy industry, especially a kind of pipeline connects the air inflation sealing device of usefulness.
Background technique
In metallurgy industry, dusting apparatus is widely used, and in the installation and use of dusting apparatus, often needs to connect between the pipeline or connect two airtight containers with pipeline.These joints all need good being tightly connected, just can reach the dust removing effects of expection, especially work as the environment that container or pipeline are in vibrations, often need to adopt when flexibly connecting between the pipeline, traditional Connecting format is to adopt canvas that the joint is wrapped up, and perhaps fills in packing or the like in the slit with the joint.
Practice shows that these traditional Connecting format in use effect are not fine, when especially the air pressure in container or pipeline is malleation, is easy to leak.In case leak, the fine grained dust in container or the pipeline will be discharged into outside container or the pipeline, serious environment pollution, and infringement post workman's is healthy.
Summary of the invention
The purpose of this invention is to provide a kind of easy for installationly, simple in structure, the pipeline of good sealing effect connects the air inflation sealing device of usefulness.
The objective of the invention is to realize by following technical proposals:
Pipeline of the present invention connects the air inflation sealing device of usefulness, it is characterized in that comprising an inner sleeve that is connected with connected pipeline respectively, outer sleeve and be located at this inner sleeve, the flexibility inflation loop device of the connecting part between the outer sleeve, this flexible inflation loop device is by the last annular connecting plate that is connected with the upper end of described outer sleeve by bolt device, the following annular connecting plate that is connected with the lower end of described inner sleeve, be located at the inflation of the flexibility between the annular connecting plate and following annular connecting plate ring on this, the air inlet pipeline that flexible therewith inflation ring is connected, gas exhaust piping and therewith the inflator that is connected of air inlet pipeline form.
Adopt flange to be connected between described inner sleeve, outer sleeve and the connected pipeline or be welded to connect.Be convenient to dismounting and maintenance when adopting flange to connect; The mode that employing is welded to connect is applicable to and need not the occasion of dismantling and overhauling.
Described inflator is gas holder or compressed air line, also can be other inflator that is suitable for.
Described air inlet pipeline is provided with suction valve, gas pressure gage, is provided with outlet valve on described gas exhaust piping, this suction valve, gas pressure gage, outlet valve all with being connected of automatic controller, be convenient to flexibility inflation loop device is controlled automatically.
Described inflator is the inflator that has automatic controller, is convenient to inflator is controlled automatically.
Working principle of the present invention is:
Start inflator, suction valve will be in opening state, outlet valve will be in closed condition, pressurized gas from source of the gas enters in the flexible inflation ring by inflator, suction valve and air inlet pipeline, when the air pressure for the treatment of the pressurized gas in the flexible inflation ring reaches requirement (gas pressure gage demonstration), automatic controller will make inflator and suction valve cut out automatically, and the connection of connected pipe is just finished.
When the pipeline that connects does not need work, outlet valve will be in opening state, discharge the pressurized gas in the flexible inflation ring, and inner sleeve and outer sleeve will be in free state this moment.Change if desired or the cleaning pipeline, as long as the pressurized gas in the flexibility inflation ring is discharged, removing annular connecting plate is separable two pipelines with being connected of outer sleeve.
Advantage of the present invention is:
1) owing to adopted the sealing of inflatable flexible inflation ring, and solved the sealing problem that two pipelines need flexibly connect, flexibility inflation ring is to lean on the flexible air pressure of inflating in the ring to fit together with being connected of annular connecting plate, so whole device good airproof performance, the reliability height has improved the post operation environment.
2) because inflator has automatic controller, so flexible inflation ring can be selected supercharging or release according to the equipment operation situation.
3) flexible inflation loop device is a discontinuous operation, avoids flexible inflation ring to be in for a long time pressure state under and reduction life-span possibility, and life cycle is long.
4) simple in structure, easy for installation, change easily or the cleaning pipeline.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
As shown in Figure 1, pipeline of the present invention connects the air inflation sealing device of usefulness, it is characterized in that comprising respectively and connected pipeline 1,11 inner sleeves 2 that are connected, outer sleeve 10 and be located at this inner sleeve 2, the flexibility inflation loop device of the connecting part between the outer sleeve 10, this flexible inflation loop device is by the last annular connecting plate 7 that is connected with the upper end of described outer sleeve 10 by bolt device, the following annular connecting plate 9 that is connected with the lower end of described inner sleeve 2, be located at the inflation of the flexibility between the annular connecting plate 7 and following annular connecting plate 9 ring 8 on this, flexible therewith inflation ring 8 air inlet pipelines that are connected 3, gas exhaust piping 12 and therewith the inflator 5 that is connected of air inlet pipeline 3 form.
