Description
Technical field
The utility model relates to gas insulated metal enclosed swit chgear shell leak hunting technology field more particularly to it is a kind of use SF6Gas
The device of body progress shell leak detection.
Background technique
As China's economy continues to develop, the demand of electric power also expands increasingly, and closed group of especially each voltage class
Electric appliance is closed to be greatly developed.Such product is at runtime, it is necessary to assure shell intracorporal SF6 gas pressure is guaranteed with this
Insulating properties, therefore need to be sealed leak detection to each shell in production.However these shell lengths are different, and volume compared with
Greatly, it hunts leak if directly filling SF6 gas to inside, inevitable dosage is very big, leads to the increase of leak detection cost.
Summary of the invention
SF is used in view of the shortcomings of the prior art, the utility model provides a kind of6Gas carries out the device of shell leak detection, no
Gas usage, and wide adaptability is only greatly reduced.
The utility model is achieved by the following technical solution, and is provided a kind of using SF6Gas carries out shell leak detection
Device, water-in flange and inlet flange including being sealedly connected on shell both ends, the inlet flange are equipped with inflating port and sight
Window is examined, water pocket is sealedly connected on the one side of the water-in flange, connection water pocket and extraneous note are offered in water-in flange
The mouth of a river, and the liquid outlet above the water filling port are provided at the water filling port, liquid outlet and inflating port detachable
Blocking.
This programme when in use, first injects liquid in water pocket, increases water pocket volume, to reduce water pocket and shell
Between volume, pour SF6When gas, due to the small volume between water pocket and shell, reduce SF6The dosage of gas,
Reduce leak detection cost.
As optimization, the blocking is the silk plug being connected through a screw thread with water-in flange or inlet flange.Blocking is selected as
Silk plug, dismount it is more convenient, sealing it is highly reliable.
It further include the vacuum evacuation device being detachably connected to the water filling port or liquid outlet as optimization.It is taken out by setting
Vacuum plant, can be by vacuum pumping in water pocket, convenient for the injection of liquid, convenient for grasping fluid injection situation by pressure.
As optimization, the pressure gauge of detection water intraluminal pressure is additionally provided in the water-in flange.Water is detected by pressure gauge
Intracapsular pressure is more convenient the control fluid injection time.
The beneficial effects of the utility model are：Increase water pocket volume by injecting liquid in water pocket, to reduce shell
Internal inflatable volume, reduces SF6Gas usage, reduces production cost, and have structure is simple, be easily installed and
The features such as repairing, is safe and reliable has preferable practicability and promotion prospect.

Specific embodiment
In order to clarify the technical characteristics of the invention, being illustrated below by specific embodiment to this programme.
It is a kind of to use SF6Gas carries out the device of shell leak detection, the water-in flange 2 including being sealedly connected on 4 both ends of shell
With inlet flange 8, the inlet flange 8 is equipped with inflating port 7 and observation window 6, the company of sealing on the one side of the water-in flange 2
It is connected to water pocket 5, connection water pocket and extraneous water filling port 1 are offered in water-in flange 2, and above the water filling port 1
Liquid outlet 3, is provided with the silk plug being connected through a screw thread with water-in flange at the water filling port 1 and liquid outlet 3, at inflating port 7
It is provided with the silk plug being connected through a screw thread with inlet flange.
The present embodiment further includes the vacuum evacuation device being detachably connected to the liquid outlet, and detection is additionally provided in water-in flange
The pressure gauge 11 of water intraluminal pressure.When vacuumizing, the exhaust tube of vacuum evacuation device is connected to liquid outlet, after exhausting, will be evacuated
Pipe is removed from liquid outlet, and liquid outlet is sealed using silk plug.
In use, including the following steps：
（1）Water-in flange and inlet flange are sealed respectively and are fixed on shell both ends, and water pocket is put in shell；
（2）Liquid 9 is injected in water pocket by the water filling port in water-in flange, the liquid 9 in the present embodiment is water, and is led to
The variation that observation window observes water pocket state is crossed, after water pocket expansion sufficiently, stops injection liquid, and use blocking by water filling port and position
Liquid outlet above water filling port is blocked；
（3）SF is poured into shell by inflating port6Gas 10, until stopping when air pressure reaches 0.3 ~ 0.5Mpa in shell
Gas pours, and is blocked inflating port using blocking；
（4）The weld seam on shell is detected using leak detector；
（5）After the completion of detection, inflating port is passed through into pipeline and SF6Gas concentration unit connection, by the intracorporal SF of shell6Gas
Extraction, recyclable device pressure recovery are -0.0.5MPa, then discharge the liquid in water pocket.
Step（2）Middle water pocket expansion can sufficiently refer to that liquid outlet has liquid outflow, by making from liquid outlet trickle
For the judgment basis that fluid injection is completed, method is simple, is conducive to improve working efficiency.
It is of course also possible in step（2）In first pass through liquid outlet to vacuumizing in water pocket, fluid hole is blocked up after vacuumizing
Firmly, liquid is then injected in water pocket again, the water pocket expansion in this step sufficiently refers to that water intraluminal pressure reaches 0.1Mpa.Pass through
Water pocket internal pressure judges whether fluid injection is enough, the amount of liquid of injection can be made bigger, to be further reduced SF6Gas is used
Amount.
The present apparatus when in use by water pocket fluid injection make its volume increase, to reduce inflatable sky in shell
Between, reduce SF6The dosage of gas reduces leak detection cost, and easy to operate, and applicability is wide, can be applied to a variety of rule
The shell of lattice is hunted leak.
Certainly, above description is also not limited to the example above, and technical characteristic of the utility model without description can lead to
It crosses or realizes that details are not described herein using the prior art；Above embodiments and attached drawing are merely to illustrate the technology of the utility model
Scheme is not limitations of the present invention, and the utility model is described in detail referring to preferred embodiment, this
Field it is to be appreciated by one skilled in the art that those skilled in the art institute in the essential scope of the utility model
The variations, modifications, additions or substitutions made without departure from the objective of the utility model, want by the right that also should belong to the utility model
Seek protection scope.
