Abstract
The utility model discloses a high tightness composite communicating pipe. The high tightness composite communicating pipe comprises a communicating pipe body. Portions at two ends of the communicating pipe body are respectively provided with inner connecting threads, an anticorrosion pipe layer is sleeved on the inner surface of the communicating pipe body in a sealed mode, two ends of the anticorrosion pipe layer respectively extend to inner end tips of the two inner connecting threads, the two ends of the anticorrosion pipe layer are respectively arranged into circular-truncated-cone-shaped transitional connection ports, and sealing grooves are formed in the inner surfaces of the transitional connection ports. The inner connecting threads arranged on the portions at two ends of the communicating pipe body achieve connecting of pipe fittings, and therefore additional connecting pipe fittings are not needed. The arranged sealing grooves are matched with the pipe body in use, and therefore sealing performance of connection of the pipe body can be achieved. The arranged anticorrosion pipe layer can effectively improve corrosion resistance of the communicating pipe, and therefore service life of the communicating pipe can be prolonged greatly, and saving of pipes can be benefited.
Description
Technical field
The utility model relates to a kind of compound connecting tube, relates in particular to high compound connecting tube of a kind of sealability.
Background technique
That uses at present often only has one deck pipe structure various connecting tube, and body self two end part do not arrange any connection set yet, when carrying out the pipeline connection, need to utilize the connection pipe fitting and the seal arrangement that arrange in addition connect sealing, operate more loaded down with trivial detailsly, and use rear sealing effect obviously to descend for a long time, the part body is because the corrosivity of fed sheet of a media simultaneously, significantly descend working life, needs the replacing body of not timing, is unfavorable for saving tubing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of compound connecting tube of high leak tightness simple, that Corrosion Protection is good that connects.
For solving the problems of the technologies described above, the technical solution of the utility model is: compound connecting tube of high leak tightness, comprise the connecting tube body, described connecting tube, the body two end part were provided with respectively interior connecting thread, described connecting tube body internal surface stuffing box gland is provided with the anti-corrosion pipe layer, described anti-corrosion pipe layer two ends extend to respectively the inner termination of two described interior connecting threads, and described anti-corrosion pipe layer two ends are set to respectively the transition connecting port of frustoconic shape, and described transition connecting port internal surface is provided with seal groove.
As preferred technological scheme, described transition connecting port is set to the from outside to inside diminishing frustoconic shape mouth of pipe of internal diameter.
As to improvement of the technical scheme, described seal groove is set to inverted trapezoidal groove.
Owing to adopted technique scheme, compound connecting tube of high leak tightness, comprise the connecting tube body, described connecting tube, the body two end part were provided with respectively interior connecting thread, described connecting tube body internal surface stuffing box gland is provided with the anti-corrosion pipe layer, described anti-corrosion pipe layer two ends extend to respectively the inner termination of two described interior connecting threads, and described anti-corrosion pipe layer two ends are set to respectively the transition connecting port of frustoconic shape, and described transition connecting port internal surface is provided with seal groove; The beneficial effects of the utility model are: the interior connecting thread of connecting tube body end setting, can realize the connection of pipe fitting, thereby avoided using extra connection pipe fitting, the seal groove that arranges cooperates body to use the sealing that realizes that body connects, and the anti-corrosion pipe layer that arranges can improve the corrosion resistance of connecting tube effectively, thereby greatly prolonged the working life of connecting tube, helped to save tubing.
Description of drawings
The following drawings only is intended to the utility model done and schematically illustrates and explain, does not limit scope of the present utility model.Wherein:
Accompanying drawing is the utility model embodiment's structural representation;
Among the figure: 1-connecting tube body; Connecting thread in the 2-; 3-anti-corrosion pipe layer; The 4-seal groove.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.
As shown in drawings, compound connecting tube of high leak tightness, comprise connecting tube body 1, described connecting tube, body 1 two end part were provided with respectively interior connecting thread 2, interior connecting thread 2 is used with the outer connecting thread of pipe fitting end, realizes the connection of pipe fitting, and then has avoided using extra pipe connecting device, reduce the pipeline link cost and connected operation, helped to improve pipeline connection construction efficient.
Described connecting tube body internal surface stuffing box gland is provided with anti-corrosion pipe layer 3, help to improve the anticorrosive property of connecting tube, prolong its working life, the anti-corrosion pipe layer can utilize any anti-corrosion material of prior art to make, be the known content of those of ordinary skill in the art, here repeat no more.
The layer of anti-corrosion pipe described in the present embodiment 3 two ends extend to respectively the inner termination of two described interior connecting threads 2, and described anti-corrosion pipe layer 3 two ends are set to respectively the transition connecting port of frustoconic shape, described transition connecting port is set to the from outside to inside diminishing frustoconic shape mouth of pipe of internal diameter, to guarantee the happy property of fed sheet of a media circulation in connecting tube, prevent vibration, guaranteed Security in improving the pipeline use.
Described transition connecting port internal surface is provided with seal groove 4, and described seal groove 4 can be set to inverted trapezoidal groove, cooperates body to use, and sealing effect is better, thereby avoids increasing extra seal arrangement, helps to reduce the operation that pipe fitting connects, and increases work efficiency.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
