Embodiment
Below in conjunction with drawings and Examples, mode of execution of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.In addition, term " first ", " second " only for describing object, and can not be interpreted as instruction or hint relative importance.
Flanged connecting structure of the present utility model, comprises the first pipeline 1 and second pipe to be connected, and the afterbody of the first pipeline 1 is billiard table shape, and offers the center hole for realizing pipeline flow on described billiard table shape afterbody; The afterbody periphery of second pipe is provided with flange plate 7; The billiard table shape afterbody of described first pipeline 1 is connected with pressing plate 2, and under described pressing plate 2 acts on, the outer surface of billiard table shape afterbody of described first pipeline 1 and the interior of the end of described second pipe are along realizing sealing; Described pressing plate 2 is connected with described flange plate 7 by fastening piece 3.Flanged connecting structure in the utility model is used for the connection between pipeline and pipeline, concrete form can be the connection between pipeline and the cylinder body comprising pipeline configuration, also can be only the connection between pipeline, below in conjunction with different embodiments, the utility model is described.
Embodiment one
Refer to Fig. 2, the flanged connecting structure of the present embodiment one, comprise the first pipeline 1 and second pipe to be connected.Wherein, the first pipeline 1 is pipe connector, and its afterbody is billiard table shape, and obviously in order to realize pipeline flow, this billiard table shape afterbody must offer center hole, and namely the effect of this center hole is equivalent to the effect of circulation passage.Second pipe is arranged on cylinder interior, and the flange plate 7 being arranged on second pipe periphery belongs to the constituent element of cylinder body body.Wherein, the billiard table shape afterbody of the first pipeline 1 comprises two parallel bottom surfaces, and is connected with pressing plate 2 away from the bottom surface of joint, and under the effect of pressing plate 2, the spherical outer surface of billiard table shape afterbody is interior along contacting with the end of second pipe.Particularly, the billiard table shape afterbody of described first pipeline 1 can enter into the inside of second pipe at least partly.Wherein, the afterbody of preferred second pipe is the joint pipeline section comprising step hole, thus makes the spherical outer surface of above-mentioned billiard table shape afterbody interior edge that is direct and this joint pipeline section realize sealing.In addition, flange plate 7 also comprises the cushion cap of joint pipeline section periphery; The interior of end of described cushion cap is provided with sealing gasket 5 along position; The interior edge of the described outer surface of the first pipeline 1 billiard table shape afterbody and the end of described second pipe realizes sealing by described sealing gasket 5.Because sealing gasket 5 produces plastic deformation under the effect of fastening force, therefore can fit with the intimate of the first pipeline 1 billiard table shape afterbody, thus ensure sealing effect.Wherein, the hardness of the material of sealing gasket 5 is less than the hardness of pipe connector, is specifically as follows metal or the good nonmetallic material of plasticity such as rubber, resin, copper, aluminium.
Refer to Fig. 3, in the present embodiment one, preferably on described pressing plate 2, offer some fastening piece attachment holes, fastening piece 3 is connected with the flange plate 7 of cylinder body through after described fastening piece attachment hole, thus drive the afterbody of the first pipeline section towards the motion of cylinder body direction, and then realize the sealing between the first pipeline 1 and second pipe.Wherein, fastening piece 3 is preferably clamping bolt, is now connected by pad between this clamping bolt and pressing plate 2.
In order to make the billiard table shape afterbody of first pipeline 1 of the present embodiment one can fit with the sealing gasket 5 in cushion cap when any angular slope, the normal connection between pressing plate 2 and cylinder body must be ensured.In view of the foregoing, the present embodiment one provides a kind of fastening piece attachment hole comprising circular counter bore 2a and cone shape hole 2b, refers to Fig. 4.Wherein, circular counter bore 2a is positioned at the top of cone shape hole 2b, and is connected with cone shape hole 2b.It is emphasized that the internal surface of described circular counter bore 2a is the same with the external surface shape of billiard table.In order to ensure the connection precision between clamping bolt and pressing plate 2, the pad between clamping bolt and the circular counter bore 2a of pressing plate 2 is spherical washer 4, and its upper surface is plane, and lower surface is spherical, thus and circular counter bore 2a cooperation.Owing to being ball contact between spherical washer 4 and pressing plate 2, therefore this spherical washer 4 opposing platen 2 can free inclination.When the first pipeline 1 billiard table shape afterbody is at any angular slope, pressing plate 2 also can tilt thereupon, thus can not damage the first pipeline 1 by pressure; Meanwhile, the fastening piece 3 on pressing plate 2 not along with pressing plate 2 tilts and run-off the straight, thus remains normal annexation between pressing plate 2 and cylinder body, refers to Fig. 5.
Embodiment two
Refer to Fig. 6, with embodiment one unlike, in embodiment two, second pipe periphery is provided with flange plate 7, and this flange plate 7 is independently structures, is not attached to cylinder body or other devices.Therefore, when fastening piece 3 is bolt, bolt passes flange plate 7 through after fastening piece attachment hole, and the other end of bolt is tightened by nut 6.
Above mode of execution only for illustration of the utility model, but not to restriction of the present utility model.Although be described in detail the utility model with reference to embodiment, those of ordinary skill in the art is to be understood that, various combination, amendment or equivalent replacement are carried out to the technical solution of the utility model, do not depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
