Abstract

The utility model relates to a pipe connector, wherein a rubber ring is sheathed in a metal shell; the two ends of the rubber ring are provided with sealing lips; and the sealing lips are of the double-lip structure. The pipe connector has simple and reasonable structure, the double-lip structure of the sealing lips of the sealing rubber rings can provide the double security guarantees for pipe connection, thereby ensuring the best sealing property of a pipe under low/high working pressure; when a bolt of the pipe connector is screwed tightly, whether the pipe works under the vacuum negative pressure or the high pressure, the opening between the two lips forms buffering, and the inner lip is overlapped on the outer lip, so that the flanging of the sealing lips can not be caused, and the sealing effect is best; when the pressure in a pipeline is risen, the tighter the compaction of the sealing lips is, and the better the sealing effect is. In addition, a metal protection gasket is additionally arranged in the sealing rubber ring, thereby effectively preventing the axial dislocation of the pipe connection and avoiding the damage to the sealing rubber ring caused by the dislocation of the pipe connection and cutting, so as to ensure the sealing effect, enhance the connection reliability and prolong the service life.

Description

Pipe jointer
Technical field
The utility model relates to assembling pipe joint.
Background technique
Assembling pipe joint is the important device during the every profession and trade pipeline connects, and the assembling pipe joint of strict demand is more particularly arranged for sealing, pipeline error compensation etc., and the quality of its structure and performance directly influences the effect of pipeline.At present straight tube connect general adopt flange and pipe jointer arranged, flange plate is a kind of being rigidly connected, effect is not as pipe jointer in pressure piping, have rubber seal in the pipe jointer metal shell, sealing effect and dismounting aspect all are better than flange, but there is also substantial not enough problem, the one, the seal ring sealing lip adopts single procheilon structure, when in low working pressure following time, sealing effect can guarantee, but when pipeline in negative pressure of vacuum or condition of high voltage following time, sealing lip lip limit is under the relative external broach effect of pipeline and dig, sealing effect descends, even loses seal action.The 2nd, when the pipe head of butt joint produces axially dislocation in the pipe jointer, cause pipeline fail in shear rubber sealant easily, influence sealing effect.
Summary of the invention
The purpose of this utility model is the problem that overcomes present pipe jointer sealability deficiency, provide a kind of simple in structure, sealing effect is good, long service life, safe and reliable pipe jointer.
The technological scheme that the utility model is adopted for achieving the above object is: pipe jointer, and metal shell liner rubber ring, the rubber ring two ends have sealing lip, and sealing lip is the lips structure.
Described sealing lip is the lips structure that has otch between epipharynx and the outer lip, and otch is straight line type or arc.
Install the metal coating liner additional in the seal ring between the described sealed at both ends lip.
Described metal coating liner is the stainless steel protection liner that is curled and formed by Stainless Steel Band.
The utility model is simple and reasonable, the sealing lip of rubber seal adopts the lips structural design, for sealing for tubing joints provides dual safety assurance, guaranteed the optimal seal effect of pipeline under low (height) working pressure, when tightening the pipe jointer bolt, no matter pipeline is operated in negative pressure of vacuum or under condition of high voltage, opening between the lips has formed buffering, epipharynx is laminated on the outer lip, can not cause the sealing lip flange, and sealing effect is better, the sealing lip design of this special lips formula, when the pipeline internal pressure raise, the sealing lip compacting was tight more, and sealing effect is good more.
Add the metal coating liner in the utility model rubber seal in addition, can effectively prevent the pipeline coupling shaft, avoid the pipeline dislocation and shear the damage that causes rubber seal to dislocation.Guarantee sealing effect, increase the reliability that connects, increase the service life.
