Abstract

The utility model discloses a detachable fastening and sealing device for a testing pipeline medium parameter. A circular fastening and sealing ring is arranged on a flange end of an outer sleeve, and a first threaded sealing ring is arranged at the other end of the outer sleeve. A claw type elastic sealing ring is arranged in an inner sleeve, and a second threaded sealing ring is arranged at the other end of the inner sleeve. The inner sleeve is arranged in the outer sleeve and provided with the second threaded sealing ring, of which one end passes through the first threaded sealing ring and is situated outside the outer sleeve. A test tube sequentially passes through the second threaded sealing ring, a test tube and the claw type elastic sealing ring and is movably connected with the second threaded sealing ring and the claw type elastic sealing ring. The detachable fastening and sealing device facilitates testing of pipeline medium parameters, prevents leakage of medium in a pipeline, ensures the safety of test work, and improves test efficiency and test precision.

Description

Detachable fit sealing device for the pipeline medium parameter testing
Technical field
The utility model relates to a kind of detachable fit sealing device for the pipeline medium parameter testing.
Background technology
In to various pipeline medium parameter testing processes, general pipeline internal medium all has certain pressure, there is the pipeline medium of many required tests to contain the high-risk gas of poisonous and harmful, the leakage of these gases brings injury or equipment is caused to damage the tester, as adopt the conventional seals mode to carry out the pipeline medium parameter testing very easily to produce potential safety hazard, and the testing efficiency low consumption is long with the time, while is due to the existence of pressure leakage in test process, the data of surveying can not reflect the actual parameter of pipeline internal medium fully, pressure as pipeline internal medium, flow velocity, the parameters such as air quantity and pollutant levels and distribution situation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of detachable fit sealing device for the pipeline medium parameter testing, utilize this device can conveniently implement the pipeline internal medium parameter testing, avoid the leakage of pipeline internal medium, guarantee the security of test jobs, improved testing efficiency and measuring accuracy.
For solving the problems of the technologies described above, the utility model comprises that for the detachable fit sealing device of pipeline medium parameter testing an end is provided with the outer tube of flange, inner sleeve, testing tube, the claw type elastic sealing ring, the fastening sealing ring of circle cover, the first thread seal collar and the second thread seal collar, the fastening sealing ring of described circle cover is located at the flange end of described outer tube, described the first thread seal cover is located on the other end of described outer tube, described claw type resilient seal is located in described inner sleeve, described the second thread seal cover is located on described inner sleeve one end, the end that described inner sleeve is positioned at described outer tube and is provided with the described second thread seal collar is positioned at outside described outer tube through the described first thread seal collar, described testing tube penetrates the described second thread seal collar successively, testing tube and claw type elastic sealing ring also are flexibly connected with the described second thread seal collar and claw type elastic sealing ring.
The detachable fit sealing device that is used for the pipeline medium parameter testing due to the utility model has adopted technique scheme, the circle that is this device overlaps the flange end that fastening sealing ring is located at outer tube, the first thread seal cover is located on the other end of outer tube, the claw type resilient seal is located in inner sleeve, the second thread seal cover is located on inner sleeve one end, the end that inner sleeve is positioned at outer tube and is provided with the second thread seal collar is positioned at outside outer tube through the first thread seal collar, testing tube penetrates the second thread seal collar successively, testing tube and claw type elastic sealing ring also are flexibly connected with the second thread seal collar and claw type elastic sealing ring.This device can conveniently be implemented the pipeline internal medium parameter testing, avoids the leakage of pipeline internal medium, has guaranteed the security of test jobs, has improved testing efficiency and measuring accuracy.
The accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is this structural representation for the detachable fit sealing device of pipeline medium parameter testing.
Embodiment
As shown in Figure 1, the utility model comprises that for the detachable fit sealing device of pipeline medium parameter testing an end is provided with the outer tube 1 of flange 4, inner sleeve 2, testing tube 3, claw type elastic sealing ring 7, the fastening sealing ring 5 of circle cover, the first thread seal collar 6 and the second thread seal collar 8, the fastening sealing ring 5 of described circle cover is located at flange 4 ends of described outer tube 1, the described first thread seal collar 6 is located at the other end of described outer tube 1, described claw type elastic sealing ring 7 is located in described inner sleeve 2, the described second thread seal collar 8 is located at described inner sleeve 2 one ends, the end that described inner sleeve 2 is positioned at described outer tube 1 and is provided with the described second thread seal collar 8 is positioned at outside described outer tube 1 through the described first thread seal collar 6, described testing tube 3 penetrates the described second thread seal collar 8 successively, testing tube 3 and claw type elastic sealing ring 7 also are flexibly connected with the described second thread seal collar 8 and claw type elastic sealing ring 7.
This apparatus structure is simple, and cheap, and the flange 4 of outer tube 1 one ends adopts the DN standard flange, can be applicable to the sealing demand of dissimilar pipeline internal medium parameter testing.During the pipeline medium parameter testing, the flange 4 of outer tube 1 one ends is overlapped to fastening sealing ring 5 connecting tube flanges 9 by circle, experimental test pipe 3 is in the degree of the second thread seal collar 8 and the 7 interior flexible movements of claw type elastic sealing ring, pushing tow testing tube 3 one ends are against the instrument connection 91 of pipe flange 9, pipeline internal medium hole 91 after tested flows into testing tube 3, and testing tube 3 other end linking parsing instrument can be implemented the test of medium parameter.This device overlaps fastening sealing ring by circle and the first thread seal collar is implemented sealing, by claw type elastic sealing ring and the second thread seal collar, testing tube implemented to sealing outer tube and inner sleeve, in test process if any dielectric leakage, the medium leaked is restricted in outer tube, avoid the excessive of pipeline medium, guaranteed the security of test process; This device only needs joint flange and mobile test pipe can implement test jobs simultaneously, thereby has improved the efficiency of test jobs, by a plurality of seals, avoids pipeline medium to leak and has also improved measuring accuracy.In this device, each parts can adopt stainless steel to make, and guarantee that rig-site utilization do not corrode; That package unit is connected is closely sealed, flexible operation, sealing are good, fully demonstrate dismountable characteristics, but flexible Application is in the sealing test of the parameter of different pipeline mediums.This device outer tube one end can be furnished with the DN series standard flange of plurality of specifications, can meet the test request of different size pipeline.
