Abstract
The utility model belongs to wavy metal tubular union, particularly metal bellows jointing.Metal bellows jointing, it comprises the joint body with through hole, one end of joint body stretches out formation terminal board, it is characterized in that: the outer wall of joint body is provided with the flexible sealing ring identical with metal bellows ripple, described terminal board is connected with the hold-down ring that can simultaneously tighten up to center, the internal surface of described hold-down ring is provided with the compression grooved ring corresponding with flexible sealing ring, described terminal board is connected with the adjusting handle regulating hold-down ring.The metal bellows jointing that the utility model can freely be dismantled, there is good sealing effect, be convenient to carry out with changing to metal bellows after aging breaking appears in metal bellows, jointing, without the need to scrapping together along with breaking of metal bellows, reduces maintenance cost.
Description
Technical field
The utility model belongs to wavy metal tubular union, particularly a kind of metal bellows jointing of good sealing effect.
Background technique
Traditional metal bellows connect time, generally adopt by bellows-welding on jointing, when employing welded joint, the thinner problem that easily there is melting in welding process of the wall thickness due to metal bellows, causes the problem that sealing effect is undesirable.
Model utility content
The utility model is for the deficiencies in the prior art, devise a kind of metal bellows to be flexibly connected with joint, the metal bellows jointing that can freely dismantle, there is good sealing effect, be convenient to carry out with changing to metal bellows after aging breaking appears in metal bellows, jointing, without the need to scrapping together along with breaking of metal bellows, reduces maintenance cost.
The utility model is achieved through the following technical solutions:
Metal bellows jointing, it comprises the joint body with through hole, one end of joint body stretches out formation terminal board, it is characterized in that: the outer wall of joint body is provided with the flexible sealing ring identical with metal bellows ripple, described terminal board is connected with the hold-down ring that can simultaneously tighten up to center, the internal surface of described hold-down ring is provided with the compression grooved ring corresponding with flexible sealing ring, described terminal board is connected with the adjusting handle regulating hold-down ring.
Form a conical surface between described terminal board and joint body, the internal surface of the end of described hold-down ring is provided with the compression conical surface with cone match.
The end of described joint body is provided with the tilted conical surface conveniently entering metal bellows.
The end of described joint body is provided with sealing inclined-plane.
The end of described joint body is provided with the counterbore concentric with through hole, is provided with the seal ring sealed in described counterbore.
The utility model has the following advantages: the utility model devises a kind of novel clamping mode, overcome conventional metals bellows-welding and connect the defect that there is melting and cause sealing effect difference, the utility model is provided with the flexible sealing ring identical with metal bellows ripple, flexible sealing ring is adopted to be convenient to metal bellows to be enclosed within jointing on the one hand, simultaneously also can after hold-down ring compresses, flexible sealing ring is close to the inwall of metal bellows, ensure sealing effect between the two, injury to metal bellows when simultaneously the utility model adopts flexible sealing ring also can reduce compression, ensure the integrity of metal bellows, what adopt between the utility model and metal bellows in addition is dismountable Placement, can change metal bellows after aging breakage appears in metal bellows, do not need to scrap jointing, reduce the user cost of jointing.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.Wherein:
Fig. 1 is structural representation of the present utility model;
In figure, 1 is sealing inclined-plane, and 2 is seal ring, and 3 for compressing grooved ring, and 4 is terminal board, and 5 is adjusting handle, and 6 is hold-down ring, and 7 is flexible sealing ring, and 8 is tilted conical surface, and 9 is joint body, and 10 is the conical surface, and 11 for compressing the conical surface.
embodiment
Metal bellows jointing as shown in Figure 1, it comprises the joint body 9 with through hole, one end of joint body 9 stretches out and forms terminal board 4, it is characterized in that: the outer wall of joint body 9 is provided with the flexible sealing ring 7 identical with metal bellows ripple, described terminal board 4 is connected with the hold-down ring 6 that can simultaneously tighten up to center, the internal surface of described hold-down ring 6 is provided with the compression grooved ring 3 corresponding with flexible sealing ring 7, described terminal board 4 is connected with the adjusting handle 5 regulating hold-down ring.
Form a conical surface 10 between described terminal board and joint body, the internal surface of the end of described hold-down ring is provided with the compression conical surface 11 with cone match.
The end of described joint body is provided with the tilted conical surface 8 conveniently entering metal bellows.
The end of described joint body is provided with sealing inclined-plane 1.
The end of described joint body is provided with the counterbore concentric with through hole, is provided with the seal ring 2 sealed in described counterbore.
The utility model has the following advantages: the utility model devises a kind of novel clamping mode, overcome conventional metals bellows-welding and connect the defect that there is melting and cause sealing effect difference, the utility model is provided with the flexible sealing ring identical with metal bellows ripple, flexible sealing ring is adopted to be convenient to metal bellows to be enclosed within jointing on the one hand, simultaneously also can after hold-down ring compresses, flexible sealing ring is close to the inwall of metal bellows, ensure sealing effect between the two, injury to metal bellows when simultaneously the utility model adopts flexible sealing ring also can reduce compression, ensure the integrity of metal bellows, what adopt between the utility model and metal bellows in addition is dismountable Placement, can change metal bellows after aging breakage appears in metal bellows, do not need to scrap jointing, reduce the user cost of jointing.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
