Abstract
The utility model relates to a reducing pipeline connector which comprises a clamping hoop and a rubber ring, wherein both side walls of the clamping hoop are respectively fixed in grooves of two pipelines with different diameters; the inner wall of the clamping hoop is embedded and laid with the rubber ring; the end faces of the long side wall and the short side wall of the rubber ring are respectively sealed on the outer surfaces of the pipeline with a small pipe diameter and the pipeline with a large pipe diameter; the inner side face of the long side wall is provided with an axial flange; the inner diameter in the position of the long side wall of the rubber ring is smaller than the outer diameter of the pipeline with a small pipe diameter; the inner diameter in the position of the short side wall of the rubber ring is smaller than the outer diameter of the pipeline with a large pipe diameter. The reducing pipeline connector of the utility model ensures the rubber ring not being dislocation to exert the expansion sealing performance of the rubber ring so as to ensure the sealing performance of the pipeline connection; simultaneously, the utility model can reduce the engineering cost of users (which comprises the installation cost and the procurement cost of pipe fittings) so as to reduce the fund investment of pipe fitting company.
Description
Technical field
The utility model relates to pipe joint, particularly a kind of link of reducing pipeline.
Background technique
Existing pipe joint, particularly reducer pipe connecting, majority is made up of cushion rubber and clip.As shown in Figure 1, this reducer pipe connecting relatively simple for structure, cushion rubber is affixed on the clip inwall, is enclosed within the connection part of reducing pipeline.General, near connection part, all have a circle groove on two tube walls of reducing.The two side of clip just is embedded in the groove of reducing two tube walls, thereby the position of clip is fixed.At the inner chamber of clip, the chimeric cushion rubber that is furnished with, the end face of long sidewall of described cushion rubber and short sidewall is sealed in the outer surface of small-caliber pipeline and big-diameter pipeline respectively.
Yet as shown in Figure 1, this cushion rubber is uncontrolled, and is not bad when it is subjected to malleation, in case the pipeline pressure release produces vacuum, the cushion rubber place will laterally be tilted to the right, and makes cushion rubber lip limit and seal for pipe joints place produce dislocation, produces seepage.
The model utility content
In order to address the above problem, the utility model has been proposed.Its purpose is, provides a kind of and cooperates the inclination of controlling cushion rubber with clip, cushion rubber, caliber three tacit agreement, prevents dislocation, and then prevents the reducer pipe connecting of seepage.
Reducer pipe connecting of the present utility model comprises: clip and cushion rubber.The two side of described clip is individually fixed in the groove of two pipelines of reducing, described clip inwall, and the chimeric cushion rubber that is furnished with, the long sidewall of this cushion rubber and the end face of short sidewall are sealed in the outer surface of small-caliber pipeline and big-diameter pipeline respectively.The inner side surface of described long sidewall is provided with axial ledge, and the axial clearance of the flange surface of described flange and big-diameter pipeline end face is 0.5～1mm; Perhaps, be arranged at intervals with projection on inner side surface one annulus of described long sidewall, the convex surface of this projection contacts with the big-diameter pipeline end face, and the groove surface that forms between adjacent two projections and the end face of big-diameter pipeline leave axial clearance, and this axial clearance is 0.5～1mm.
Described cushion rubber is grown the external diameter of the internal diameter of side-walls less than small-caliber pipeline at it, and described cushion rubber is lacked the external diameter of the internal diameter of side-walls less than big-diameter pipeline at it.
Reducer pipe connecting of the present utility model, as shown in Figure 2, even when producing vacuum in the pipe, the end face of big-diameter pipeline can push up flange, then can guarantee that cushion rubber does not misplace, the Expansion sealing of performance cushion rubber, and then guaranteed the sealing that pipeline connects.Because of described cushion rubber adopts the lips self-fastening ring, when suppressing to pipeline, medium (mainly referring to fire water, life water and gas etc.) will enter the cushion rubber inner chamber by described gap in the pipe, when the pipe internal pressure raises, also pressurized in succession around the inner chamber, thus play expansion.The pipe internal pressure is big more, and the cushion rubber pressurized is big more, pastes tightly more with tube wall, and expansion effect is good more, thereby plays better sealing effect.Simultaneously, the utility model can reduce user's engineering cost, has reduced the fund input of pipe fitting company, economical with materials; Installation speed is fast, reduces cost.

Embodiment
Below, in conjunction with the accompanying drawings reducer pipe connecting of the present utility model is elaborated.
As shown in Figure 2, reducer pipe connecting of the present utility model comprises: clip 1 and cushion rubber 2.The two side of described clip 1 is individually fixed in the groove of two pipelines of reducing, described clip inwall, and the chimeric cushion rubber that is furnished with, the long sidewall of this cushion rubber 2 and the end face of short sidewall are sealed in the outer surface of small-caliber pipeline and big-diameter pipeline respectively.The inner side surface of described long sidewall is provided with axial ledge, and when the axial clearance of the flange surface 4 of described flange and big-diameter pipeline end face was 0.5～1mm, sealing effect be the best.
Described cushion rubber is grown the external diameter of the internal diameter of side-walls less than small-caliber pipeline at it, and described cushion rubber is lacked the external diameter of the internal diameter of side-walls less than big-diameter pipeline at it.
As shown in Figure 3, another embodiment's of reducer pipe connecting of the present utility model projection cube structure.Be arranged at intervals with projection on inner side surface one annulus of described long sidewall, the convex surface of this projection contacts with the big-diameter pipeline end face, and the groove surface that forms between adjacent two projections and the end face of big-diameter pipeline leave axial clearance, and this axial clearance is 0.5～1mm.Described projection and groove are evenly distributed on the described annulus, and both length can be identical, also can be different.
Before installation, cushion rubber 2 is horizontal looseness 1～1.5mm in clip 1, cushion rubber 2 give in advance one of steel pipe suitable give tight power, realize giving the requirement of tight power less than the outer diameter of steel pipes of corresponding position by the cushion rubber internal diameter.Medium (mainly referring to fire water, life water and gas etc.) is not when having pressure, and medium does not ooze out, and this gives tight power is qualified.
After clip 1 closes, give distance 0.7～1.2mm of cushion rubber radial compression, during the medium pressurized, do not allow to leak out.
