The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described.
The elastic connection structure of a kind of large nuclear power station equipment gate between double containment, as Figure 1-5, comprise primary containment 7 and outer containment 6 are coupled together run through shell ring 1 and will run through the expansion joint 2 that shell ring 1 couples together, described expansion joint 2 is the wavy parts of resilient bilayers, the wavy texture of expansion joint 2 has diameter and the radian of tangential displacement that can load bearing equipment, the two ends of expansion joint 2 by connector 3 with run through shell ring 1 and be connected.
When expansion joint 2 is rubber components, screwed hole 8 longitudinally is set on described connector 3, below screwed hole 8, horizontally set leads to the detection hole 9 of the seal cavity be comprised of double-deck expansion joint 2, screwed hole 8 is connected with detection hole 9, and expansion joint 2 is tightly connected with connector 3 by screw 4 and pressure ring 5.Pressure ring 5 is fraction block structure.
When expansion joint 2 is metal parts, expansion joint 2 welds together with connector 3, because equipment transports into from the outside, the outside is installation end, for ease of installing, make the diameter that runs through shell ring 1a at outer containment 6 places be greater than the diameter that opposite side runs through shell ring 1b, as shown in Figure 1.
In one embodiment, the elastic connection structure 10 of large nuclear power station equipment gate between double containment, as Figure 1-5, comprise expansion joint 2, run through shell ring 1 and connector 3, run through shell ring 1a outside arranging between outer containment 6 and primary containment 7, in arranging, primary containment 7 inside run through shell ring 1b, elastic connection structure 8 is arranged between outer containment 6 and primary containment 7, expansion joint 2 by connector 3 will run through outward shell ring 1a and in run through shell ring 1b and couple together, screwed hole longitudinally is set on connector 3, expansion joint 2 is fixed on connector 3 closely by screw 4 and pressure ring 5.But described expansion joint 2 loaded axles are to the displacement with tangential; Expansion joint 2 is double-decker, expansion joint 2 forms with connector 3 space of sealing, threaded detection hole 9 laterally is set on connector 3, detecting hole 9 is connected with screwed hole 8, can pass into gas from screwed hole 8 expansion joint 2 is carried out to seal tightness test, and can be regular expansion joint 2 is changed, easy to operate, for convenience of the installation of expansion joint, the expansion joint described in the present embodiment is made by elastomeric material.
The structure of screwed hole and pressure ring described in embodiment 1 is the mode that expansion joint 2 adopts can't weld mutually with connector 3 time, if expansion joint 2 and connector 3 are same metalloid material, can cancel screw 4 and pressure ring 5, directly by expansion joint 2 with together with connector 3 is soldered to, simultaneously for ease of installing, can make the diameter difference that runs through shell ring 1 of the relative both sides of equipment gate, should be greater than the diameter of opposite side at the diameter that runs through shell ring 1 installation side, the diameter that runs through shell ring 1a at outer containment 6 places is greater than the diameter that opposite side runs through shell ring 1b.
The structure of expansion joint 2 as shown in Figure 2, expansion joint 2 be one with a wave structure, the displacement that wherein wave number of expansion joint 2, wavelength and inside and outside bend radius all will provide according to different operating modes is calculated and is chosen rational structure, and this expansion joint should be able to the load bearing equipment gate runs through axial displacement and the tangential displacement of shell ring.
