Description
Technical field
The utility model relates to a kind of automatic force-boosting constructional device, particularly a kind of sealing-plug self sealss force-increasing mechanism.
Background technology
At present, on reactor to the channel seal of reloading hermetically-sealed construction commonly used be: on sealing-plug top one seal sleeve is installed, the opening of the channel that reloads is welded with a groove that sn-bi alloy is housed, and seal sleeve is inserted in the sn-bi alloy; In the time of need opening sealing-plug, earlier sn-bi alloy is heated to fusing point (140 ℃), treats that sn-bi alloy all melts, utilize gearing that sealing-plug is opened then.When the passage that reloads need seal sealing-plug is resetted, the sn-bi alloy temperature is reduced to about 50 ℃, and sn-bi alloy solidifies, the characteristic that expands with cold and contracts with heat according to the sn-bi alloy channel seal of will reloading.
Its weak point is: when sealing-plug is mentioned, communicate with the transhipment chamber in the heap, sodium steam in the heap is to the transhipment chamber, sodium steam forms the crystallization of some sodium oxide molybdenas, some can fall into these crystallizations in the sn-bi alloy groove, the fusing point of sn-bi alloy is changed, make heating-up temperature be difficult to obtain control, and then influence the operate as normal of sealing-plug.This in addition hermetically-sealed construction also needs some other auxiliary equipment (as electric heater etc.), and its structure is huge and complicated.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of simple in structure, and volume is little, in light weight, simple to operate, conducting oneself with dignity by sealing-plug just can be with the force-increasing mechanism of the channel seal of reloading.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of sealing-plug self sealss force-increasing mechanism, comprise two levers, three-point attachment, connecting rod, counterweight, support, lifting gear etc., two levers intersect to be assembled, and an end of lever links to each other with three-point attachment, and the other end links to each other with connecting rod, connecting rod and bearing are hinged, bearing is fixed on the flange, and counterweight moves up and down in seal sleeve by the hole on the flange, and sealing gasket is installed on the flange.
Described three-point attachment is the triangle flat board, and lifting gear is a pull bar.
Compared with prior art, the utility model is simple in structure, utilize lever principle to realize the effect of reinforcement cleverly, well satisfy the requirement of sealing, this structure is utilized rope directly to sling or is put down sealing-plug and just the duct of reloading can be sealed or opens, simple to operate, volume is little, in light weight, safe and reliable, this device can be used on the various devices that need reinforcement, thereby has the excellent popularization using value.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
This self sealss force-increasing mechanism is made up of two levers 7, three-point attachment 6, connecting rod 8, counterweight 11, support 4, lifting gear 5 etc.Two levers 7 intersect to be assembled, and an end of lever 7 links to each other with three-point attachment 6, and the other end then links to each other with connecting rod 8, connecting rod 8 is hinged with bearing 3, bearing 3 is fixed on the flange 9, and counterweight 11 moves up and down in seal sleeve 1 by the hole on the flange 9, and sealing gasket 2 is installed on the flange.Described three-point attachment 6 is the triangle flat board, and lifting gear 5 is a pull bar.
As accompanying drawing 1 is sealing-plug self sealss mechanism working state schematic representation, when reactor refuling finishes, put down sealing-plug, at first sealing gasket 2 contacts and compresses with opening of the channel 10 sealing surfaces that reload earlier, sealing-plug no longer moves down, at this moment it is descending in sleeve 1 that lifting gear 5 is being with counterweight 11 beginnings, the weight average of counterweight 11 is added in the end of two levers 7, because three-point attachment 6 links to each other with counterweight 11, so it is descending that three-point attachment 6 continues, and bearing 3 maintains static, and at this moment force-increasing mechanism begins action.Two levers are respectively around axle 12,13 rotations, and connecting rod is the center rotation with bearing axle 14,15 then, and at this moment the other end of two levers withstands support item plate, and according to acting force and reacting force, same rack plate imposes identical pressure to sealing-plug.This device can be according to selected gasket material, and the length and the counterweight that change the bar thick stick reach seal request.Illustrate force-increasing mechanism is stressed in the accompanying drawing 1: the long-armed long 250mm of present lever 7, and galianconism is 45mm, the length ratio of two arms is 250/45: 1, counterweight 11 about 420Kg, the power that is distributed on each lever 7 is 210Kg, according to lever principle, suffered power should be 250/45 * 420=2333.3Kg on two levers, 7 summits, add the weight (about 420+210=630Kg) of sealing-plug body itself and counterweight 11 then, so the sealing general pressure that acts on the sealing gasket is 2963.3Kg=29041N.Promptly when sealing-plug was in sealing state, the pressure that sealing-plug produces sealing gasket was 4.7 times of sealing-plug deadweight, had satisfied the seal request of sealing-plug, had reached good sealing effectiveness.
When the reactor cold-refueling, utilize hoisting mechanism to mention pull bar 5 earlier, pull bar 5 is being with counterweight 11 and three-point attachment 6 to move up together, and three-point attachment 6 is being with two levers 7 also to move up, and pull lever 7 is rotated around axle 12,13; Because can only rotating, can not move by connecting rod 8 again, so connecting rod 8 is that rotate at the center with bearing axle 14,15, two levers 7 are inwardly received, when counterweight is covered stroke, distance between two levers is less than the support outlet diameter, at this moment pull bar 5 is being with whole sealing-plug to extract the duct of reloading together out, finishes the unlatching of sealing-plug smoothly.
