Abstract
A conduit for anti-impurity blocking, is characterized in that: the conduit of described anti-impurity blocking, comprises conduit, lining; Conduit and lining are interference fit, and catheter diameter is greater than the internal diameter of lining, and the transmission medium that lining is positioned at conduit flows into end place; The size that lining has a series of external diameter different.Advantage of the present utility model: the conduit of anti-impurity blocking described in the utility model, employing can guide-tube structure for convenience detach and more resleeve, at duct entry, the less lining of internal diameter is set, effective realization is to the interception of impurity in inflow catheter, and by designing the different lining of a series of external diameter, realize the replacing to blocking lining.Catheter main body can repeatedly use, and effectively reduces the waste of material.
Description
Technical field
The utility model relates to the catheter arts of transmission medium, the conduit of particularly a kind of anti-impurity blocking.
Background technique
The conduit transmitting certain medium is often used in industrial production and daily life.When conduit diameter is less, when the dielectric clean degree of transmission is not high, be easy to occur catheter blockage phenomenon, finally cause conduit media feature to lose efficacy.For the conduit that internal diameter is less, be very difficult to the removing of inner impurity and dredging, at this moment, the conduit blocked can only be abandoned, and adopt new product to substitute, for the metallic material that part price is more expensive, the waste of material and the increase of product maintenance cost can be caused.
For this reason, a kind of guide-tube structure of anti-impurity blocking need be designed, avoid the waste of material because catheter blockage replacing conduit causes and maintenance cost to increase.
Model utility content
The purpose of this utility model is to reduce because catheter blockage changes the waste that whole conduit causes, overcoming the deficiency that conventional catheters internal diameter is consistent, and spy provides a kind of conduit of anti-impurity blocking.
The utility model provides a kind of conduit of anti-impurity blocking, it is characterized in that: the conduit of described anti-impurity blocking, comprises conduit 1, lining 2;
Conduit 1 and lining 2 are interference fit, and conduit 1 internal diameter is greater than the internal diameter of lining 2, and the transmission medium that lining 2 is positioned at conduit flows into end place; The size that lining 2 has a series of external diameter different.
When assembling first, the minimum gauge elastic conjunction of conduit 1 and lining 2, when the internal diameter of impurity blocking lining 2, lining 2 is taken out from conduit 1, now, on conduit 1, φ A hole can because dismounting wearing and tearing cause oversize, cannot again with the minimum gauge elastic conjunction of new lining 2, therefore work need be added in hole to φ A on conduit 1, ensure the second specification part elastic conjunction of conduit 1 and lining 2; By that analogy, the cleaning of impurity in conduit can be realized and reuse.
The two ends of described lining 2 are outside with chamfering.
The two ends of described lining 2 are inner with chamfering.
On the basis of conventional catheters simple structure, design kind of guide-tube structure that is detachable and more resleeve.Lining is assemblied in the entry end of conduit, and bushing inner diameter is less than catheter diameter, effectively stops that impurity is to the blocking of catheter diameter, by changing the lining of blocking, avoids changing the waste that whole conduit causes.
Conduit 1 and lining 2 are interference fit, and conduit 1 internal diameter is greater than the internal diameter of lining 2, and lining 2 is that the transmission medium of conduit flows into end.The size that lining 2 has a series of external diameter different, between each specification, size has difference.When assembling first, the minimum gauge elastic conjunction of conduit 1 and lining 2, when the internal diameter of impurity blocking lining 2, lining 2 is taken out from conduit 1, now, on conduit 1, φ A hole can because dismounting wearing and tearing cause oversize, cannot again with the minimum gauge elastic conjunction of new lining 2, therefore work need be added in hole to φ A on conduit 1, ensure the second specification part elastic conjunction of conduit 1 and lining 2; By that analogy, the cleaning of impurity in conduit can be realized and reuse.
Advantage of the present utility model:
The conduit of anti-impurity blocking described in the utility model, employing can guide-tube structure for convenience detach and more resleeve, at duct entry, the less lining of internal diameter is set, effective realization is to the interception of impurity in inflow catheter, and by designing the different lining of a series of external diameter, realize the replacing to blocking lining.Catheter main body can repeatedly use, and effectively reduces the waste of material.

Embodiment
Embodiment 1
Present embodiments provide a kind of conduit of anti-impurity blocking, it is characterized in that: the conduit of described anti-impurity blocking, comprises conduit 1, lining 2;
Conduit 1 and lining 2 are interference fit, and conduit 1 internal diameter is greater than the internal diameter of lining 2, and the transmission medium that lining 2 is positioned at conduit flows into end place; The size that lining 2 has a series of external diameter different.
When assembling first, the minimum gauge elastic conjunction of conduit 1 and lining 2, when the internal diameter of impurity blocking lining 2, lining 2 is taken out from conduit 1, now, on conduit 1, φ A hole can because dismounting wearing and tearing cause oversize, cannot again with the minimum gauge elastic conjunction of new lining 2, therefore work need be added in hole to φ A on conduit 1, ensure the second specification part elastic conjunction of conduit 1 and lining 2; By that analogy, the cleaning of impurity in conduit can be realized and reuse.
The two ends of described lining 2 are outside with chamfering.
The two ends of described lining 2 are inner with chamfering.
On the basis of conventional catheters simple structure, design kind of guide-tube structure that is detachable and more resleeve.Lining is assemblied in the entry end of conduit, and bushing inner diameter is less than catheter diameter, effectively stops that impurity is to the blocking of catheter diameter, by changing the lining of blocking, avoids changing the waste that whole conduit causes.
Conduit 1 and lining 2 are interference fit, and conduit 1 internal diameter is greater than the internal diameter of lining 2, and lining 2 is that the transmission medium of conduit flows into end.The size that lining 2 has a series of external diameter different, between each specification, size has difference.When assembling first, the minimum gauge elastic conjunction of conduit 1 and lining 2, when the internal diameter of impurity blocking lining 2, lining 2 is taken out from conduit 1, now, on conduit 1, φ A hole can because dismounting wearing and tearing cause oversize, cannot again with the minimum gauge elastic conjunction of new lining 2, therefore work need be added in hole to φ A on conduit 1, ensure the second specification part elastic conjunction of conduit 1 and lining 2; By that analogy, the cleaning of impurity in conduit can be realized and reuse.
