Description
Technical field
The utility model relates to a kind of high temperature heavy caliber bearing pipe be applied in petroleum chemical industry.
Background technique
To the compound restricted type expansion joint for the high temperature heavy caliber bearing pipe in petroleum chemical industry, when needs absorb large lateral displacement or length of pipeline limits, the middle adapter of expansion joint needs the very long of design, especially for large diameter pipeline, now the weight of middle adapter excessively can strengthen the stress of expansion joint inside, so need establish spring hanger to carry on expansion joint.As shown in Figure 5, spring support hanging frame root structure part 11 directly welds with middle adapter 5 prior art.
Existing structure as shown in Figure 5, expansion joint is when system cloud gray model, counter spring force can be applied directly on two bellowss by the spring of taking root in middle adapter, to produce on bellows that excessive counter-force is loaded into both sides and cause bellows to damage when sometimes have selected inappropriate spring or spring failure; The structure of prior art makes middle adapter be in free state, and when expansion joint bears elevated pressures or absorbs larger lateral displacement, expansion joint easily unstability occurs; Structural Static load excessive in expansion joint middle adapter and produce without constraint aperiodicity displacement, also can be applied on single bellows, the displacement that bellows absorbs exceedes its design rated displacement and causes corrugated pipe fatigue life greatly to reduce even premature failure.
Model utility content
The purpose of this utility model is exactly same for above-mentioned the deficiencies in the prior art, provides one to effectively prevent expansion joint unstability, ensure that the band spring hanger of the safe operation of system and the expansion joint of tranquilizer.
The technical solution adopted in the utility model is as follows:
A kind of expansion joint with spring hanger and tranquilizer, it is characterized in that it includes middle adapter, the two ends of middle adapter are connected with one end of two bellowss respectively, the other end of described two bellowss is all connected with adapter assembly one end of respective respective side, the tube wall of described middle adapter is connected with tranquilizer one end, the tranquilizer the other end and spring prop up device for hoisting and are connected, the middle part of main hinge board component is connected with tranquilizer, and the two ends of main hinge board component are connected with the secondary hinge plate assembly be fixed on above-mentioned two adapter assemblies respectively.
Described tranquilizer is made up of two blocks of parallel-plates and vertical plate, and vertical plate is fixed between described two blocks of parallel-plates.
Described main hinge board component is connected with vertical plate by bolt.
Described main hinge board component is provided with two pieces, and they are connected with two blocks of parallel-plates respectively by bolt.
Described main hinge board component is connected with secondary hinge plate assembly by bearing pin.
Described main hinge board component is connected with secondary hinge plate assembly by cross bearing pin.
The inner side of described two bellowss is equipped with inside lining sleeve.
The beneficial effects of the utility model have:
The utility model swelling red sandstone is out of shape when long-time running normally, media flow steady, meet the expectation requirement of user to the pipe-line equipment safe operation cycle.
The outside load-carrying construction part of the utility model expansion joint is established spring hanger to take root device, counter spring force is made to be delivered to expansion joint two ends by spring hanger device and outside load-carrying construction part, instead of be applied directly on bellows, ensure that the safety reliability of bellows.
The tranquilizer that expansion joint outside is established constrains the rotation of middle adapter, effectively prevent expansion joint unstability, ensure that the safe operation of system.The Structural Static load acting on middle adapter transfers to expansion joint two ends by tranquilizer, and the displacement preventing bellows to absorb exceedes scope of design, ensures bellows normal service in system operation.
A kind of structure of the utility model is the secondary band spring hanger of hinge plate+pin shaft structure of employing one group of main hinge plate+two group and the multiple hinge type expansion joint of tranquilizer, and Absorbable rod is parallel to the lateral displacement of hinge plate plane and bears bellows pressure thrust.Another kind of structure is the secondary band spring hanger of hinge plate+cross pin axle construction of employing two groups of main hinge plate+two groups and the universal double-jointed hinge type expansion joint of tranquilizer, and Absorbable rod is appointed the lateral displacement perpendicular to any direction of expansion joint axis and born bellows pressure thrust.
