Abstract
The utility model discloses a ferrule-type connector, comprising a connector body for connecting pipelines, a ferrule and a nut. The utility model is characterized in that the ferrule comprises a front ferrule and a back ferrule. The conical surface of the front end of the front ferrule is matched with the internal conical surface of the connector body, the back end of the front ferrule is matched with the conical surface of the front end of the back ferrule, and the back end of the back ferrule is connected with the nut. The taper of the conical surface of the front end of the front ferrule is 25 to 35 degrees, and the taper of the conical surface of the front end of the back ferrule is 60 to 80 degrees. Compared with prior art, the utility model is a ferrule-type connector having the characteristics of simple structure, easy processing, good gripping effect and high sealing effect.
Description
Technical field
The utility model relates to a kind of stainless steel FERRULETYPE pipeline joint that is applied to FERRULETYPE the pipeline joint, particularly a kind of high-strength corrosion-resisting of pipeline connection.
Background technique
FERRULETYPE pipeline joint is the strength member of a kind of extensive application on fluid line connects, be pipeline to be connected on the FERRULETYPE pipeline joint by nut extruding cutting ferrule, widely used on the contemporary world is the single hoop of ISO8431-1 cutting ferrule structure, the standard GB 3765 of China " Bite type fittings technical specifications " also only refers to single hoop cutting ferrule structure, this cutting ferrule plays chucking and sealing double action, therefore in use, sometimes be difficult to guarantee the double requirements that tightens and seal, using effect is poor, and, single hoop cutting ferrule processed complex, the cost height.
Summary of the invention
Technical problem to be solved in the utility model is exactly at above-mentioned the deficiencies in the prior art, tightens effective and and the high FERRULETYPE pipeline joint of sealability and provide a kind of.
For solving the problems of the technologies described above, the utility model adopts following technological scheme, it is made up of the joint body that is connected with pipeline, cutting ferrule and nut, described cutting ferrule is made of preceding card and back card, the inner conical surface of the preceding card front end conical surface and joint body adapts, before the card rear end adapt with the back card front end conical surface, card rear end, back links to each other with nut.
The tapering of the front end conical surface of card is 25-35 ° before described, and the tapering of the back card front end conical surface is 60-80 °.
Compared with prior art, the utlity model has following characteristics, cutting ferrule is made of preceding card and back card two-part, preceding card is mainly used in seal action, and the back card is mainly used in the chucking fixation, and preceding axis is to extrusion pipe and joint body internal surface, the effect lower front end that then is stuck in nut produces a radial force and blocks pipeline, in preceding card sealing, the back card has also been finished the effect of chucking fixing tube, has improved the resistance to shock of pipeline.Behind card and the back card, design of part was oversimplified, and is easy to processing before cutting ferrule was divided into.The tapering of the tapering of the less preceding card front end conical surface and the bigger back card front end conical surface, when making two cards mobile vertically, preceding card front end blocks front end than the back and is subjected to bigger radial component, and the chucking fixation was finished in back card redeformation after card was finished seal action earlier before guaranteeing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a card structure schematic representation before the utility model.
Fig. 3 is a card structure schematic representation behind the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, as shown in Figure 1, form by the joint body 1 that is connected with pipeline, cutting ferrule and nut 4, described cutting ferrule is made of preceding card 2 and back card 3, before the inner conical surface of the card 2 front end conical surfaces and joint body 1 adapt, preceding card 2 rear ends adapt with the back card 3 front end conical surfaces, the back is blocked 3 rear ends and is linked to each other with nut 4.
The tapering of the front end conical surface of card 2 is 25-35 ° before described, and the tapering of the back card 3 front end conical surfaces is 60-80 °, and in Fig. 2, Fig. 3, the tapering of the front end conical surface of preceding card 2 is 30 °, and the tapering of the back card 3 front end conical surfaces is 70 °.
Claims (2)
1. FERRULETYPE pipeline joint, form by the joint body that is connected with pipeline, cutting ferrule and nut, it is characterized in that described cutting ferrule is made of preceding card and back card, the inner conical surface of the preceding card front end conical surface and joint body adapts, before the card rear end adapt with the back card front end conical surface, card rear end, back links to each other with nut.
2. FERRULETYPE pipeline joint according to claim 1 is characterized in that the tapering of the front end conical surface of described preceding card is 25-35 °, and the tapering of the back card front end conical surface is 60-80 °.
