Abstract
The utility model discloses a multi-welding-seam structure for improving energy storage welding encapsulation performance of a blast valve igniter. The multi-welding-seam structure comprises the blast valve igniter formed by a base and an encapsulation casing, wherein at least two welding strips are arranged between the base and the encapsulation casing, and the base and the encapsulation casing are fixedly connected through the welding strips. The multi-welding-seam structure has the benefits as follows: the tensile and shear strength of the blast valve igniter are improved considerably, and meanwhile, the airtightness of the blast valve igniter after encapsulation can be further improved.
Description
Technical field
The utility model relates to firer's technical field, is mainly used in used in nuclear power station explosive valve, is specifically related to a kind of many welding line structures of igniter stored energy welding sealing property for explosive valve that improve.
Background technique
Explosive valve is the exclusive safety valve of current state-of-the-art three generations's nuclear power station, can effectively alleviate and prevent nuclear power station generation serious accident, explosion unit is the core component of explosive valve, also be the maximum difference of explosive valve and common nuclear safety valve, igniter is in explosion unit, directly to receive the device of valve opening signal (characteristic current pulse signal), is one of Primary Component of explosive valve.
Because explosive valve is safety valve, must be after the nuclear power station generation serious accident (as earthquake) still can reliably working in two to three days, and after nuclear power station has an accident, explosive valve surrounding environment is very complicated and severe, ambient temperature can reach 220 degree left and right, simultaneously, explosive valve also will be subject to the effect of boric acid vapor pressure, therefore, guarantee that explosive valve can be in normal reliable effect under accident conditions, complete set function, prevent nuclear power plant accident upgrading, need the igniter can be in earthquake, after receiving valve opening signal under high temperature and the comprehensive function of boric acid steam, still get angry reliably and the cased charge of igniting, therefore, igniter must have high tightness and shock resistance.Adopt the explosive valve of energy storage spot welding encapsulation to there is higher tightness with igniter, yet the tension of this igniter weld and shearing strength are lower.
Model utility content
The utility model has overcome in prior art adopting only about 0.3mm of the common distance between the toes of a weld of wall scroll welding between the pedestal of explosive valve igniter and encapsulating shell, the deficiency that the tension of weld joint and shearing strength are lower, provides a kind of welded structure of many weldings that adopts can increase substantially many welding line structures of igniter stored energy welding sealing property for the raising explosive valve of weld joint tension and shearing strength.
The utility model is by the following technical solutions:
A kind of many welding line structures that improve explosive valve use igniter stored energy welding sealing property, comprise the explosive valve igniter being formed by pedestal and encapsulating shell, between described pedestal and encapsulating shell, be provided with at least two weldings, and described pedestal is fixedly connected with by welding with described encapsulating shell.
In the technical program by adopting many weldings to weld the pedestal in explosive valve igniter and encapsulating shell, by increasing the quantity of welding on packing casing and then increasing exponentially total distance between the toes of a weld, thereby increase substantially tension and the shearing strength of explosive valve igniter, the explosive valve igniter tightness after encapsulation also will further improve simultaneously.
Further technological scheme is, described welding quantity is two.
Further technological scheme is, the height of described welding is 0.6mm.
Further technological scheme is, the width of described welding is 0.3mm.
Compared with prior art, the beneficial effects of the utility model are:
Increase substantially tension and the shearing strength of explosive valve igniter, the explosive valve igniter tightness after encapsulation also will further improve simultaneously.
Accompanying drawing explanation
Fig. 1 is that a kind of embodiment's of the utility model raising explosive valve is used the structural representation of igniter with many welding line structures borehole blasting valve of igniter stored energy welding sealing property.
Fig. 2 is the structural representation of encapsulating shell in many welding line structures of igniter stored energy welding sealing property for a kind of embodiment's of the utility model raising explosive valve.
In figure, 1 pedestal, 2 encapsulating shells, 3 weldings.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As depicted in figs. 1 and 2, a kind of many welding line structures that improve explosive valve use igniter stored energy welding sealing property, comprise the explosive valve igniter being formed by pedestal 1 and encapsulating shell 2, between described pedestal 1 and encapsulating shell 2, be provided with at least two weldings 3, and described pedestal 1 is fixedly connected with by welding 3 with described encapsulating shell 2, described welding 3 quantity are two, and the height of described welding 3 is 0.6mm, and the width of described welding 3 is 0.3mm.
Welding 3 will melt when capacitance energy storage discharges makes pedestal 1 and encapsulating shell 2 firm welding, the utility model is by adopting many weldings 3, thereby overcome welding 3 of available technology adopting after welding completes, distance between the toes of a weld is about 0.3mm only, cause igniter tension and the lower deficiency of shearing strength for explosive valve, the utility model is not limited to and uses 3 welding of two weldings, can also be that three weldings 3 are even more, as long as welding 3 quantity on encapsulating shell 2, more than one, just can improve anti-seismic performance and the sealability of igniter for explosive valve.
" embodiment " that spoken of in this manual, " another embodiment ", " embodiment ", etc., refer to specific features, structure or the feature in conjunction with this embodiment, described and be included at least one embodiment that the application's generality describes.In specification, a plurality of local appearance statement of the same race is not necessarily to refer to same embodiment.Furthermore, while describing a specific features, structure or feature in conjunction with arbitrary embodiment, what advocate is in conjunction with other embodiments, to realize this feature, structure or feature also to drop in scope of the present utility model.
Although model utility is described with reference to a plurality of explanatory embodiments of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and mode of executions, and these are revised and within mode of execution will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to the constituent elements of subject combination layout and/or layout.Except modification that constituent elements and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
