Description
Technical field:
The present invention relates to the adjustable connection of a kind of pipe fitting, particularly a kind ofly comprise flexible connection.
Background technique:
In boats and ships or other similar field; Warm rubber is taken over the flexible coupling member of the piping that is usually used in media such as delivering vapor in the heavy caliber, and its medium temperature is 100 ℃～200 ℃ (middle temperature), and the structural feature that warm elastomeric flex is taken in having now is; Be provided with the metal flange that can connect piping at the two ends of rubber body; Rubber body and flange inner edge are provided with the snap-together type connecting end, for guaranteeing the essential strength and stiffness of flexibility connection pipe work, in the rubber body, are provided with stiffening ring simultaneously; This ring is made of metal and is drum type, in stiffening ring middle part projection stiffening plate is arranged.In actual the use, find that there is the reliability potential safety hazard in above-mentioned existing structure, its subject matter is:
In warm elastomeric flex take over the rubber body and flange inner edge connecting end sealing reliability poor; The long-term use seals and possibly lose efficacy; Even jeopardize equipment or environment; Its main cause be this linkage structure under user mode, the stressed perseverance of rubber pipe end of body is in shearing condition, promptly has component and the trend that makes rubber connecting end cracking in this joint;
In the rubber taken over of warm elastomeric flex be prone to bubble with the metal adhesive surface, especially the adhesive surface of rubber and metal stiffening ring is prone to foaming, has reduced the reliability of middle temperature rubber adapter; Its main cause is that rubber tightness under middle temperature (100 ℃ to 200 ℃) is relatively poor relatively, and the water that coagulates of the water vapor of minute quantity and formation thereof is assembled at the relatively low adhesive surface place of temperature, after stopping logical steam; In warm rubber take over temperature and descend, at this moment rubber air tightness can recover, the water with fixed attention of gathering is difficult for oozing out; Similar one-way valve effect, along with increase service time, the steam that accumulates between rubber and the metal adhesive surface can be cumulative; When middle temperature; These steam gasification backs form has certain interior bubble of pressing, and has worsened the strength of materials and the rubber and the metal adhesive property of rubber, causes the sticking face of rubber and metal to separate the damage of taking over middle temperature rubber.
Summary of the invention:
Technical problem to be solved by this invention is, provide a kind of in warm elastomeric flex take over, it can in long-term under the warm operating conditions, guarantee the reliability of flexibility connection pipe body and end seal.
The technological scheme that the present invention solves the problems of the technologies described above employing is:
In warm elastomeric flex take over and include forward and backward flange, stiffening ring and rubber body; Forward and backward flange, stiffening ring and the sulfuration of rubber body are one-body molded; The prominent head of forward and backward rubber that the forward and backward prominent head interlocking of the forward and backward groove of forward and backward flange and forward and backward flange has the rubber body; Be characterized in: the two ends that middle temperature elastomeric flex is taken over are respectively arranged with the forward and backward ring of withholding; This is forward and backward withholds the common structure of withholding that constitutes the prominent head of forward and backward rubber that is equipped with the rubber body of the forward and backward prominent head of ring and forward and backward flange, on the ring body of stiffening ring, offers one group of hole that bonds.In the middle of warm elastomeric flex when taking in carrying warm medium, the above-mentioned prominent head of withholding in the structure of forward and backward rubber is high pressure situation, rubber can make whole rubber body set up and pass through unimpeded road in the bonding hole.
The present invention adopts interference of flexibility connection pipe end or transition to withhold and forms the partial high pressure structure, eliminate the phenomenon that conventional construction medial end portions rubber is in shearing condition in use, no longer exists the component of cracking; Guarantee the reliability of flexibility connection pipe end seal, the bonding hole is set on the stiffening ring of the present invention, rubber was mobile when it increased the vulcanization of rubber on the one hand; Improve vulcanized quality, it is more that rubber makes the interior rubber perforation of adapter in the hole that bonds on the other hand, the bond area of Reinforced Rubber and metal; But the stretching action balance bubble of rubber or water pressure with fixed attention in the bonding hole; Also can not expand even crackle occurs, stiffening ring is inside and outside to connect because the bonding hole forms simultaneously, can significantly reduce the generation that metal and rubber junction plane coagulate water; Can eliminate adhesive surface foaming phenomenon, the reliability that warm rubber is taken in obviously improving.
