Description
Technical field
The utility model belongs to converting equipment field, especially a kind of SF6 gas safety making-up air device.
Background technique
The SF6 gas making-up air device of prior art has the following disadvantages: the first, charged mend SF6 gas to equipment time, easily there is inflated hose and joint is damaged, equipment SF6 gas leaks in a large number after fracture phenomenon; The second, effectively can not discharge air and moisture in loading line before inflation; Therefore should improve prior art.
Model utility content
For the problems referred to above, the utility model aims to provide and a kind ofly can effectively prevent gas from leaking in a large number and the effective SF6 gas safety making-up air device of residual air and moisture in discharge tube.
For realizing this technical purpose, the utility model provides following technological scheme:
A kind of SF6 gas safety making-up air device, comprise pressure regulator valve, gas opening and closing gate valve one, three-way valve, check valve, tape travel check valve joint, inflated hose and gas opening and closing gate valve two, described pressure regulator valve is connected with gas cylinder, described gas opening and closing gate valve one is connected with pressure regulator valve by inflated hose, described check valve is connected with tape travel check valve joint by inflated hose, and described tape travel check valve joint is connected with charger.
As further program of the utility model: be provided with three-way valve between described check valve and gas opening and closing gate valve one.
As further program of the utility model: described three-way valve first end is connected with gas opening and closing gate valve one by inflated hose, described three-way valve second end is connected with gas opening and closing gate valve two by inflated hose, and described three-way valve the 3rd end is connected with check valve by inflated hose.
Compared with prior art, the beneficial effects of the utility model are: functionally: the first, charged mend SF6 gas to equipment time, after there is the situation such as SF6 inflated hose and joint breakage, fracture, can effectively control to leak in a large number at the equipment of fortune SF6 gas; The second, can effectively discharge residual air and moisture before inflation.In structure: the first, charged mend SF6 gas to equipment time, after there is the situation such as SF6 inflated hose and joint breakage, fracture, can effectively prevent inflated hose whipping from touching the danger of charging equipment initiation; The second, staff, by three-way valve and gas opening and closing gate valve, better controls whole tonifying Qi process.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure: 1-pressure regulator valve, 2-gas opening and closing gate valve one, 3-three-way valve, 4-check valve, 5-tape travel check valve joint, 6-inflated hose, 7-gas opening and closing gate valve two.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of SF6 gas safety making-up air device, comprise pressure regulator valve 1, gas opening and closing gate valve 1, three-way valve 3, check valve 4, tape travel check valve joint 5, inflated hose 6 and gas opening and closing gate valve 27, described pressure regulator valve 1 is connected with gas cylinder, described gas opening and closing gate valve 2 is connected with pressure regulator valve 1 by inflated hose 6, described three-way valve 3 first end is connected with gas opening and closing gate valve 2 by inflated hose 6, described three-way valve 3 second end is connected with gas opening and closing gate valve 27 by inflated hose 6, described three-way valve 3 the 3rd end is connected with check valve 4 by inflated hose 6, described check valve 4 is connected with tape travel check valve joint 5 by inflated hose 6, described tape travel check valve joint 5 is connected with charger.
Working principle of the present utility model: charged mend SF6 gas to equipment time, pressure regulator valve 1 is connected on gas cylinder, is regulated by the gas pressure that gas cylinder is discharged, then connects gas opening and closing gate valve 1 to control beginning and the stopping of gas replenishment process by inflated hose 6; Gas opening and closing gate valve 1 is connected a three-way valve 3 with between check valve 4 with inflated hose 6, and on three-way valve 3, connect a gas opening and closing gate valve 27, by residual air and moisture in the effective discharge tube of gas opening and closing gate valve 27 on three-way valve 3 before inflation, if there is the situation such as inflated hose 6 and joint breakage, fracture during inflation, can make inflated hose 6 within personnel control scope; One end connecting band stroke check valve joint 5 (i.e. equipment gas-charging connection) of check valve 4.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
