Abstract

The utility model belongs to field of construction and installation, and discloses a flange connecting piece which comprises an axial sleeving and a flange. The axial sleeve tube is an H-shaped casting. The edge of the axial sleeving is provided with a threaded hole. The edge of the circumference of the flange is provided with a through hole matched with the threaded hole of the axial sleeving. The axial sleeving is connected with the flange through a fastening screw rod. The flange connecting piece also comprises a fastening ring. The axial sleeving forms a stepped structure at the inner sides of two ends, and the inner diameter of the port of the axial sleeving is bigger than that of the middle part. The flange connecting piece connects a pipeline, having good sealing effect, simple installation process and long service life.

Description

A kind of flange connector
Technical field
The utility model belongs to the construction and installation field, is specifically related to a kind of pipe joint.
Background technique
Flange is requisite parts during pipeline connects, general two flange plate that adopt of pipeline adpting flange are fixed on the sleeve pipe by screw at present, both are by crush seal, and pipe coupling generally forms the loop configuration of the projection of mating with flange so that be connected with flange by die casting or welding.Pipe coupling is by die-casting process, and than higher, cost is than higher for the requirement of equipment; And, then form two weld seams to I haven't seen you for ages by welding, and may there be weld defects thus, influence the sealability and the withstand voltage properties of pipeline.
The model utility content
The purpose of this utility model is to provide a kind of cost lower, and installation and maintenance are simple, long service life, the flange connector of good airproof performance.
For achieving the above object, the utility model adopts following scheme: a kind of flange connector, comprise axial sleeve pipe and flange plate, axially sleeve pipe be " worker " shape foundry goods, and axially sleeve edge is provided with screw, and the flange plate circumferential edges is provided with the through hole that mates with the axial screw of sleeve pipe, axially sleeve pipe is connected by fastening screw with flange plate, described flange connector also comprises retaining ring, and described axial sleeve pipe is the inboard step-like structure that forms at two ends, and the port internal diameter is greater than the stage casing internal diameter.
More excellent, retaining ring is a landolsring.
More excellent, the retaining ring internal surface has at least one ring, and described ring is raised line or groove.
More excellent, the ring body thickness of retaining ring is radially thickened by two side direction centers.
More excellent, axially the port of sleeve pipe is tilted conical surface and retaining ring coupling.
More excellent, be arranged with rubber seal on the retaining ring.
The flange connector beneficial effect that adopts the technical program to make is, owing to the utlity model has the retaining ring structure that contains the inclined-plane, during installation, put retaining ring on the pipeline, and be connected with connector main body, can also give retaining ring the sheathed rubber seal that goes up, by tightening fastening screw, under the pressure effect of fastening screw, deformation can take place in the retaining ring front-end and back-end, because thickness is variant, thereby retaining ring is closed with level, the connecting tube good sealing effect, installation process is simple, long service life, and the connection main body need not processed the saving cost.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples
As shown in Figures 1 to 4, a kind of flange connector, comprise axial sleeve pipe 1, flange plate 2 and retaining ring 4, axially sleeve pipe is " worker " shape foundry goods, and the flange plate circumferential edges is provided with through hole 21, and axially sleeve pipe 1 edge is provided with the screw corresponding with flange plate 11, axially sleeve pipe 1 is connected by fastening screw 3 with flange plate 2, described axial sleeve pipe 1 is the inboard step-like structure that forms at two ends, and port one 3 place's internal diameters are greater than stage casing 12 internal diameters, and axially port one 3 places of sleeve pipe 1 are tilted conical surface and retaining ring 4 couplings.On retaining ring 4 pipeline that first quilt cover is set to flange is connected, then retaining ring 4 is moved to connection part, afterwards flange plate 2 is connected with axial sleeve pipe 1 by fastening screw 3, retaining ring 4 is locked in flange plate 2 and axial sleeve pipe 1, reach the effect of locked sealing.Thereby be arranged with the space between rubber seal 5 closure fange dishes 2 and the retaining ring 4 on the retaining ring 4.
Fig. 5, Fig. 6 are a kind of example structure of retaining ring 4, and the ring body thickness of retaining ring 4 is along axially being thickened by middle mind-set both sides, and retaining ring 4 outer walls form the inclined-plane.Fig. 7, Fig. 8 are the another kind of example structure of retaining ring 4, and retaining ring 4 outer walls present cydariform, intermediate projections.One breach 41 is arranged on the retaining ring 4, be landolsring, and also be provided with at the internal surface of retaining ring 4 and encircle 42 at least together.Ring 42 is a groove as Fig. 6, is cord tissue as Fig. 8.The extension characteristics of fabricated metals extruding has been considered in the design of breach and ring, makes pipeline and link locking thereby deformation can take place when mounted for pipeline and landolsring.Adopt the utility model, the connecting tube good sealing effect, installation process is simple, long service life.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
