Description
Technical field
The present invention relates to a kind of rubber compensator.
Background technique
Between rigid pipes, adopt when flexibly connecting, often adopt rubber compensator.Present rubber compensator can be divided into 3 kinds according to the difference of end seal structure, is respectively: 1) as stiffening ring, the pull-out force that this structure itself can be born is lower with steel traveler for the ball end of body.2) the ball end of body is an all-sealed structure, that is: end seal face external diameter is identical with body lap joint flange external diameter, has bolt to pass from its end.When hole in factory in this structure end,, reduced anti-pull-off the enhancement layer destroyed.In addition, according to the difference of pressure, specification of the same race need be made the multiple tool of touching, and increases manufacture cost; 3) form by rubber spheroid and two split flanges that are symmetricly set on rubber spheroid two ends, the split flange is by the side of groove (or dovetail) shape contiguous block attached to the rubber spheroid, and vertically split flange and groove (or dovetail) shape contiguous block are fixed together with bolt, cross section is arranged is the circular oval or square metal stiffening ring of rectangle to iron chains in the end flange of rubber spheroid.With bolt nut the split flange is connected with equipment to be connected or piping flange during installation, and with the clamping of ball end of body flange wherein.
These several rubber compensators have the following disadvantages:
1, in use, effect owing to fluid pressure in the rubber spheroid can make the rubber spheroid deform, the result can make the ball end of body slope inwardly, be that ball end of body end face can not closely knitly contact with equipment or piping flange, cause producing between ball end of body and equipment or the piping flange and leak, sealing effect is undesirable, occurs pulling distortion when serious.
2, be provided with vertically because connect the bolt of split flange and rectangle contiguous block, when being full of highly pressurised liquid in the rubber compensator, the split flange can be subjected to the radial force effect, and the bolt that connects split flange and groove (or dovetail) shape contiguous block simultaneously can be subjected to the destroyed easily and generation accident of the effect of shearing force.
3, in addition, if compressive strain has taken place above-mentioned rubber compensator when mounted, then relatively difficult when the demolition rubber compensator; When decrement is big, bolt thread squeeze and destroy rubber spheroid can occur, influence working life.
Summary of the invention
The purpose of this invention is to provide a kind of good sealing effect, bear the rubber compensator of pressure height, long service life.
For achieving the above object, the present invention takes following design proposal: a kind of rubber compensator, it is characterized in that: it comprises the rubber spheroid, be symmetricly set on the split land at rubber spheroid two ends and be connected the connecting tube at described split land two ends by bolt and nut, described rubber spheroid has pipeline section and wave band two-part, described wave band is made up of planar section and land portions, cross section is arranged is the metal stiffening ring of T shape or trapezoidal or shape to iron chains in the end flange of described rubber spheroid, the connecting end of split land protrudes out a boss with through hole respectively laterally, and adjacent two split lands connect by bolt and nut at the boss place; Described split land cross section takes the shape of the letter U; Ball bulk wave section planar section is being supported in the bottom surface of described split land; Described split land internal surface matches with described rubber spheroid pipeline section outer surface; Inboard, described split land exterior edge face is provided with an annular recessed edge, the end flange of described rubber spheroid the recline bottom surface and the side of the recessed edge of described split land, the exterior edge face of the end flange of described rubber spheroid is positioned at the recessed edge of described split land annular, the inboard, exterior edge face of the end flange of described rubber spheroid is provided with an annular groove, the annular groove bottom surface and the side of the end flange of the stepped and described rubber spheroid that reclines respectively of described connecting tube interior edge face, the side of connecting tube and ball end of body flange, the inner side surface of the recessed edge of split land annular.
Described land is provided with the adjustment bolt hole, and the adjustment bolt hole place of two described split lands is provided with spacing adjustment bolt, and the two ends of described spacing adjustment bolt and middle part are bolted with the adjustment nut respectively.
Described connecting tube is provided with the through hole that is used to connect external flange.
Be fixedly connected with a cover body on the two described split lands.
The split land of described rubber spheroid one end is provided with axial screw, the split land of the described rubber spheroid the other end is provided with radially screw, described cover body bottom is provided with through hole, described cover body bottom is connected with described split land by the bolt on the axial screw that passes through hole on it and be screwed onto the split land, described faceshield side wall is provided with axial long hole, described cover body side by pass axial long hole on it be screwed onto the split land radially the bolt on the screw be connected with described split land.
Described split land is 2 lobes or many lobes.
Advantage of the present invention is: the present invention makes the end flange of rubber spheroid be not easy to deform because the cross section of metal stiffening ring wherein is T shape or trapezoidal or shape in the use, good sealing effect can not leak.In addition, land cross section among the present invention is a U-shaped, can effectively stop the distortion of rubber spheroid pipeline section, increase the intensity of rubber spheroid pipeline section part, bear the pressure height, make the damage of can not breaking of this part, ball bulk wave section planar section is being supported in the bottom surface of land, does not need movement pipeline and equipment just can roll over the dress rubber compensator by adjusting bolt, and when decrement is big, bolt thread can squeeze and destroy to the rubber spheroid, increase the service life; And because its connecting bolt is perpendicular to radial direction, it can not be subjected to shear action when the land pressurized, so good connecting effect can not leaked.Moreover, owing to connecting tube and ball end of body flange and land side fluid-tight engagement among the present invention, can effectively stop between rubber spheroid and the connecting tube to deform, leakage situation can not appear, and the pull-off phenomenon can not appear.
