Description
Technical field
The utility model relates to a kind of respirator more particularly to a kind of nuclear power station case respirators on the spot.
Background technique
It is used to monitor, control in nuclear power plant containment shell, junction box used in distribution and cable connection, if in containment
When main steam line ruptures, it will cause pressure in containment to increase, so as to cause the damage of junction box and cable.
Utility model content
The utility model aim is for overcome the deficiencies in the prior art and provides a kind of for keeping external pressure in junction box
Dynamic balance, while the condensed water into the steam generation in case can be allowed to flow out from respirator, guarantee the normal fortune of junction box
Row, to guarantee a kind of nuclear power station of the safe and stable operation of nuclear power station case respirator on the spot.
In order to achieve the above objectives, the technical solution adopted in the utility model is: including: respirator ontology, nut, hole gear
Plate, anti-dust filter mesh, box baseplate, storage box, polyvinyl fluoride silk；The respirator ontology is equipped with air inlet；The air inlet
Hole has hole baffle；The hole has storage box with baffle；Polyvinyl fluoride silk is placed in the storage box；The storage
Case has anti-dust filter mesh；The anti-dust filter mesh has venthole, and above-mentioned air inlet is greater than venthole；The breathing
Device ontology is arranged in box baseplate；The box baseplate is fixed by nut and respirator ontology.
Preferably, the respirator ontology and screw are stainless steel production.
Preferably, seal washer is equipped between the box baseplate and respirator ontology, for making box baseplate and breathing
It is in closed state between device ontology.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The utility model, to keep junction box's internal and external pressure balance, can allow entrance in the bottom of junction box installation respirator
The condensed water of steam generation in case is flowed out from respirator, guarantees the normal operation of junction box, and structure is simple, is had certain real
With value.
Detailed description of the invention
It is attached that FIG. 1 is a schematic structural view of the utility model；
Wherein: 1, respirator ontology；2, nut；3, seal washer；4, hole retaining ring；5, polyvinyl fluoride silk；6, dust-proof mistake
Strainer；7, box baseplate；8, storage box；9, venthole；10, air inlet.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
A kind of nuclear power station described in the utility model as shown in Fig. 1 case respirator on the spot, includes: respirator sheet
Body 1, nut 2, hole baffle 4, anti-dust filter mesh 6, box baseplate 7, storage box 8, polyvinyl fluoride silk 5；The respirator ontology
It is equipped with air inlet 10；The air inlet 10 has hole baffle 4；The hole baffle 4 has storage box 8；It is described to deposit
It puts and is placed with polyvinyl fluoride silk 5 in case 8；The storage box has anti-dust filter mesh 6；The anti-dust filter mesh 6 has outlet
Hole 9, and above-mentioned air inlet 10 is greater than venthole 9；The respirator ontology 1 is arranged in box baseplate 7；The box baseplate 7
It is fixed by nut 2 and respirator ontology 1；The respirator ontology 1 is stainless steel production with screw 2；The box baseplate 7 with
Seal washer 3 is equipped between respirator ontology, for making between box baseplate 7 and respirator ontology 1 in closed state.
It is indeformable in order to guarantee that junction box can bear biggish pressure when using the present apparatus, in the bottom of junction box
Installation respirator is then vented to keep junction box's internal and external pressure balance again by venthole by air inlet gas inlet hole, while can be with
It allows the condensed water of the steam generation entered in case to flow out from respirator, and is filtered by dustproof filter screen, guarantee junction box just
Often operation, to guarantee the safe and stable operation of nuclear power station.
The utility model, to keep junction box's internal and external pressure balance, can allow entrance in the bottom of junction box installation respirator
The condensed water of steam generation in case is flowed out from respirator, guarantees the normal operation of junction box, and structure is simple, is had certain real
With value.
The above is only the specific application examples of the utility model, do not constitute any limit to the protection scope of the utility model
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
