Abstract
The utility model discloses a sealed corrugated joint for connecting corrugated pipes, relating to the technical field of gas conveying pipelines; the joint structure comprises a joint body, wherein one end of the joint body is provided with a corrugated structure matched with the corrugations on the inner wall of the spiral corrugated hose, a through hole is formed in the joint body, the other end of the joint body is a connecting end, the outer surface of the middle part of the corrugated structure is wrapped with an elastic sealing layer, and the thickness of the elastic sealing layer is 0.5-2mm; the utility model discloses a wrap up the thin wall and have certain width elastic sealing layer at ripple structure middle part, because elastic layer and corrugated joint in close contact with cooperation, after corrugated joint and corrugated hose spiral cooperation, this sealing material compression is with filling firmly between corrugated joint and the corrugated hose, plays sealed effect, solves the gas leakage phenomenon between corrugated joint and the corrugated hose.
Description
Technical Field
The utility model relates to a gas transmission pipeline technical field, concretely relates to connect sealed corrugated joint for bellows.
Background
At present, need be connected the PVC pipe that inserts the coal seam with the corrugated hose who inserts the main pipeline in high gas mine gas drainage operation, traditional method is in the same place through gluing between corrugated hose and the PVC hard tube, then uses the ferrule to fasten, nevertheless because corrugated hose has special spiral cross section structure to elasticity is great, and the existence of corrugated hose and PVC hard tube pipe diameter preparation error in addition, leads to reliable sealed degree of difficulty very big, has increased the working volume. At present, a novel connection method is to connect a PVC corrugated hose by adopting a corrugated connector, and because the corrugated structure of the corrugated connector is matched with the corrugation on the inner wall of the corrugated hose, the corrugated connector can have a reliable spiral connection structure with the corrugated hose, and can play a good role in sealing. But after the spiral connection between current PVC corrugated connector and the PVC corrugated hose, because the article accuse problem in the corrugated hose production, have some products to have slight gas leakage problem to appear to lead to the product disability rate higher, increase enterprise's burden.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes prior art's is not enough, provides a connect sealed corrugated joint for bellows, has solved the problem that leaks gas appears easily behind corrugated joint and the corrugated hose connection.
In order to achieve the above purpose, the present invention is achieved by the following technical solutions.
A sealing type corrugated connector for connecting corrugated pipes comprises a connector body, wherein a corrugated structure matched with the corrugations of the inner wall of a spiral corrugated hose is arranged at one end of the connector body, a through hole is formed in the connector body, the other end of the connector body is a connecting end, an elastic sealing layer wraps the outer surface of the middle of the corrugated structure, and the thickness of the elastic sealing layer is 0.5-2mm.
Furthermore, a descending surface with the height of 0.5-1mm is circumferentially arranged in the middle of the corrugated structure, and the elastic sealing layer is wrapped on the descending surface.
Further, the width of the elastic sealing layer is 1/4-1/3 of the corrugated structure.
Furthermore, the elastic sealing layer is an elastic rubber ring, and the elastic rubber ring is sleeved on the corrugated structure and fixed through elasticity.
Furthermore, the elastic rubber ring is made of high-elasticity wear-resistant rubber.
The utility model discloses produced beneficial effect does for prior art:
the utility model discloses a wrap up a thin wall at corrugated structure middle part, and certain width elastic sealing layer, elastic layer and corrugated connector in close contact with cooperation, connect corrugated connector and corrugated hose spiral cooperation back once more on this basis, just one section elastic sealing material has been had between the two, and this sealing material compression is with packing between corrugated connector and the corrugated hose firmly, plays sealed effect, solves the gas leakage phenomenon between corrugated connector and the corrugated hose.
Drawings
Fig. 1 is a front view of the sealed bellows joint according to the present invention.
Fig. 2 is a cross-sectional view of fig. 1.
In the figure, 1 is a joint body; 2 is a corrugated structure; 3 is a through hole; 4 is an elastic sealing layer; 5 is a connecting end, and 6 is a descending surface.
Detailed Description
In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
As shown in fig. 1 and 2, the sealed corrugated connector for connecting corrugated pipes comprises a connector body 1, wherein a corrugated structure 2 matched with the inner wall corrugation of a spiral corrugated hose is arranged at one end of the connector body 1, a through hole 3 is formed in the connector body, the other end of the connector body 1 is a plug-in type connecting end 5, a descending surface 6 with the height of 0.5mm is arranged in the circumferential direction of the middle of the corrugated structure 2, the descending surface 6 is 1/4 of the width of the corrugated structure 2, an elastic sealing layer 4 with the thickness of 0.5mm is wrapped on the outer surface of the descending surface 6 in the middle of the corrugated structure 2, the elastic sealing layer 4 is a high-elasticity rubber ring made of silicon rubber, the high-elasticity rubber 1 centimeter can be stretched to 20 centimeters, and the elastic rubber ring is sleeved on the descending surface and fixed through elasticity.
After the spiral connection between current product PVC corrugated connector and the PVC corrugated hose, there is slight gas leakage phenomenon, in order to solve the sealed problem between their the two, on ripple structure 2, this embodiment falls after a take the altitude on the basis of original spiral line, sheathe in a thin wall, certain width elastic sealing material, because elastic material and ripple structure 2 in close contact with cooperation, after spiral cooperation once more with corrugated connector and corrugated hose on this basis, just one section elastic sealing material has been had between the two, this sealing material compression is with filling stout between corrugated connector and the corrugated hose, play the sealing effect, solve the gas leakage phenomenon between corrugated connector and the corrugated hose.
The above description is for further details of the present invention with reference to specific preferred embodiments, and it should not be understood that the embodiments of the present invention are limited thereto, and it will be apparent to those skilled in the art that the present invention can be implemented in a plurality of simple deductions or substitutions without departing from the scope of the present invention, and all such alterations and substitutions should be considered as belonging to the present invention, which is defined by the appended claims.
