Description
Technical field
The utility model relates to electrical equipment auxiliary appliance technical field, particularly a kind of pressure sealing storage barrel.
Background technology
In electric system, sulfur hexafluoride gas-filled equipment is a kind of comparatively common arc extinguishing auxiliary appliance, often need in its working process to utilize appendix to inflate inflatable appliance, and improving constantly along with work requirements, the storage procedure of appendix also receives the concern of people day by day.
In current existing appendix storage process, because store method is improper, appendix is very easily caused to make moist, appendix after making moist is when inflating inflatable appliance, moisture and moisture can enter sulfur hexafluoride gas-filled device interior with pipe, and the moisture entered in inflatable appliance and moisture will endanger apparatus insulated after exceeding standard, and then affect Whole Equipment arc quenching effect, and produce toxic substance, cause inconvenience to relevant constructing operation.
Therefore, how avoiding making moist in appendix storage process is the important technological problems that those skilled in the art need to solve at present.For this reason, patent name be a kind of pressure sealing storage barrel (patent No.: 201320627339.5) pressure sealing storage barrel is provided, but the contact surface between cylindrical shell and seal cover cap is comparatively coarse, still can enter moisture between cylindrical shell and seal cover cap.
Utility model content
The purpose of this utility model is to provide a kind of pressure sealing storage barrel, and this pressure sealing is deposited between cylindrical shell and seal cover cap and is provided with packing seal.
For solving the problems of the technologies described above, the utility model provides a kind of pressure sealing storage barrel, comprise cylindrical shell, the inside of described cylindrical shell has annular seal space, the top of described cylindrical shell is provided with the seal cover cap matched with described annular seal space, the top of described annular seal space is provided with the sealing arrangement suitable with described seal cover cap, is connected with securing device between described seal cover cap and described cylindrical shell; Be provided with packing seal between described cylindrical shell and seal cover cap, packing seal is the ring-type of mating with the upper surface of cylindrical shell.
Described cylindrical shell is provided with the check charge valve passing into described annular seal space for unreactable gas.
Preferably, described cylindrical shell is provided with the air-pressure gauge matched with described annular seal space.
Preferably, the top of described seal cover cap is provided with handle.
Preferably, described sealing arrangement is seal ring.
Preferably, described securing device is screw.
Relative above-mentioned background technology, the utility model is provided with packing seal 15, and when cylindrical shell 11 and seal cover cap 12 seal, packing seal 15 is squeezed distortion, makes the gap between cylindrical shell 11 and seal cover cap 12 less, plays sealing function.Reduce and enter moisture between cylindrical shell and seal cover cap.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model.
Detailed description of the invention
Please refer to Fig. 1, pressure sealing storage barrel provided by the utility model, comprise cylindrical shell 11 and seal cover cap 12, be provided with elastomeric packing seal 15 between which, packing seal 15 is the ring-type of mating with the upper surface of cylindrical shell 11, the inside of cylindrical shell 11 has annular seal space 111, the top of cylindrical shell 11 is provided with the seal cover cap 12 matched with annular seal space 111, the top of annular seal space 111 is provided with the sealing arrangement 112 suitable with seal cover cap 12, is connected with securing device (not shown) between seal cover cap 12 and cylindrical shell 11; Cylindrical shell 11 is provided with the check charge valve 13 passing into annular seal space 111 for unreactable gas.In working process, the equipment such as the appendix needing to store are put into annular seal space 111, then by described securing device, seal cover cap 12 and cylindrical shell 11 are fastened, and make to keep between seal cover cap 12 and annular seal space 111 sealing by sealing arrangement 112, in annular seal space 111, unreactable gas is passed into afterwards by check charge valve 13, check charge valve 13 can ensure the overall tightness of annular seal space 111 further, and the unreactable gas passed in annular seal space 111 can ensure the environmental drying in annular seal space 111, thus the equipment such as appendix are avoided to make moist.
When cylindrical shell 11 and seal cover cap 12 seal, packing seal 15 is squeezed distortion, makes the gap between cylindrical shell 11 and seal cover cap 12 less, plays sealing function.
Further, cylindrical shell 11 is provided with the air-pressure gauge 14 matched with annular seal space 111.In equipment running process, staff by the atmospheric pressure value in air-pressure gauge 14 Real-Time Monitoring annular seal space 111, so that in time to topping up in annular seal space 111, thus can ensure the volume drying sealing effectiveness of described pressure sealing storage barrel.
It should be pointed out that in the production operation process specific to reality, above-mentioned unreactable gas is preferably nitrogen, also can be other unreactable gass, as long as that is, can meet the actual use needs of described pressure sealing storage barrel.
On the other hand, the top of seal cover cap 12 is provided with handle 121.The operations such as the carrying that this handle 121 can make staff implement seal cover cap 12 and handling are more simple and easy to do.
In addition, sealing arrangement 112 is seal ring.Certainly, sealing device 112 is only preferred version for seal ring, and it is not limited to the seal ring shown in figure, as long as can meet the actual use needs of described pressure sealing storage barrel.
In addition, described securing device is screw.Should be clear and definite, this securing device is not limited to screw mentioned above, as long as can meet the actual use needs of described pressure sealing storage barrel.
In summary, the pressure sealing storage barrel provided in the utility model, comprise cylindrical shell, the inside of described cylindrical shell has annular seal space, the top of described cylindrical shell is provided with the seal cover cap matched with described annular seal space, the top of described annular seal space is provided with the sealing arrangement suitable with described seal cover cap, is connected with securing device between described seal cover cap and described cylindrical shell; Described cylindrical shell is provided with the check charge valve passing into described annular seal space for unreactable gas.In working process, the equipment such as the appendix needing to store are put into described annular seal space, then by described securing device, described seal cover cap and described cylindrical shell are fastened, and make to keep between described seal cover cap and described annular seal space sealing by described sealing arrangement, in described annular seal space, unreactable gas is passed into afterwards by described check charge valve, described check charge valve can ensure the overall tightness of described annular seal space further, and the unreactable gas passed in described annular seal space can ensure the environmental drying in described annular seal space, thus the equipment such as appendix are avoided to make moist.
