Abstract
The utility model provides a stopper is aerifyd to thieff hatch for monitoring of pollution sources flue gas, fills in and the rear portion cock cap including anterior gasbag even as an organic whole, and the inside of gasbag stopper and cock cap is provided with the hole that link up, is provided with the air cavity in the gasbag stopper, is provided with the pump in the cock cap, and the inflation inlet and the interior air cavity intercommunication of gasbag stopper of pump are provided with the core vent on the cock cap. When carrying out sampling monitoring, the thieff hatch is inserted with the gasbag stopper in the gun case of will the sampling hole that enters, and the cock cap is in the thieff hatch outside. The rifle of will sampling starts the pump after transferring extremely suitable position, inflates for the gasbag stopper, makes the gasbag fill in the inflation, and the gap between will sample rifle and thieff hatch is whole airtight. This thieff hatch is aerifyd the stopper and is adopted the inflatable seal structure, simple structure, and sealed effectual, the suitability is strong, prevents the gas leakage phenomenon, has guaranteed the accuracy of monitoring data.
Description
Technical field
This utility model is related to a kind of dress for sealing thieff hatch when sampling being arranged on polluter gas sampling gun
Put, belong to thieff hatch technical field of sealing technology.
Background technology
When carrying out environmental monitoring to polluter aiutage, need for sampling gun to insert thieff hatch, due to gun body and sampling
Interporal lacuna is larger, is susceptible to gas leak phenomenon, affects the accurate of Monitoring Data.
Disclosed in Chinese patent literature CN105276596A《A kind of sealing device for boiler flue thieff hatch》, including
Thieff hatch pipe and the closure being connected with described thieff hatch pipe, the mouth of pipe outer wall of described thieff hatch pipe is provided with multiple intervals
The projection of arrangement, the inwall of described closure is provided with the multiple and described raised groove being adapted, and described groove is from described close
The lower port of capping is provided with the first vertical rail, the second vertical rail and inclined plane along its inwall, and the two of described inclined plane
End is connected smoothly with described first vertical rail and the second vertical rail respectively, in described closure and the thieff hatch seal of tube
During connection, described project through turn clockwise and move to described inclined plane final along the first vertical rail of described groove
Stuck on the second vertical rail of described groove.
Disclosed in CN105784426A《A kind of flue gas thieff hatch plugging device》, intermeshing closure is had by a pair
Door, housing and driver element composition, closure gate can slide in the presence of driver element in housing.In the non-sampled period,
In the presence of driver element, closure gate engages each other to be closed thieff hatch；When sampling, closure gate under driver element pulling force effect
Open and form the circular hole communicating with the thieff hatch of chimney, sampling muzzle is inserted the thieff hatch on flue until sampling muzzle reaches
Behind the position specified, driver element promotes closure gate to clamp sampling gun outer wall, prevents flue gas in sampling process from revealing.
Although said apparatus are capable of the keying of thieff hatch, to be smoothed out the sampling work of flue dust, flue gas, anti-stopping leak
Dew, but structure is all extremely complex, operation inconvenience, the deficiency that existing polluter flue gas monitoring Sampling techniques exist.
Content of the invention
This utility model is directed to the deficiency that existing Sampling techniques exist, and provides a kind of structure simple, easy and simple to handle, sealing effect
The really good thieff hatch Inflation plug for polluter flue gas monitoring, to solve in polluter environmental monitoring work practical difficulty and to ask
Topic.
Thieff hatch Inflation plug for polluter flue gas monitoring of the present utility model, employs the following technical solutions：
This thieff hatch Inflation plug, including the front bladders plug being connected as a single entity and rear portion cock cap, the inside of gasbag plug and cock cap
It is provided with the endoporus of insertion, in gasbag plug, is provided with air cavity, in cock cap, be provided with inflator pump, the inflation inlet of inflator pump and gasbag plug
Interior air cavity connection, cock cap is provided with venting plug.
Be provided with described gasbag plug and cock cap longitudinal run through cracking of described endoporus, pack into sampling gun to facilitate.
The outside of described gasbag plug is provided with asbestos layer, to ensure the compactness filled, and prevents polluter aiutage
High temperature.
When carrying out sampling monitoring, sampling gun is packed into endoporus, gasbag plug is inserted thieff hatch, cock cap is outside thieff hatch.
Sampling gun is adjusted to after correct position, starts inflator pump, to gasbag plug inflation, so that gasbag plug is expanded, by sampling gun and thieff hatch
Between gap all airtight, prevent gas leak phenomenon it is ensured that Monitoring Data accurate.Sampling finishes, and gasbag plug is exitted,
Can be taken off.Next step monitoring can be started by said process.
This utility model adopts Inflatable sealing structure, prevent gas leak phenomenon it is ensured that Monitoring Data accurate, have
Following characteristics：
1. structure is simple, good sealing effect：The pump housing, power supply and electric-controlled switch are integrated into inside, install and easy and simple to handle.
2. strong applicability：It is specifically designed for standardization thieff hatch and devise shape and size it is achieved that to specification thieff hatch
Effectively seal.
Brief description

Specific embodiment
As shown in figure 1, the thieff hatch Inflation plug for polluter flue gas monitoring of the present utility model, entirety adopts high temperature resistant
Quality of rubber materials, including the front bladders plug 1 being connected as a single entity and rear portion cock cap 3, gasbag plug 1 and cock cap 3 be internally provided with insertion
Endoporus 2.It is provided with the air cavity 8 of annular in gasbag plug 1, so that gasbag plug 1 is expanded by the inflation into air cavity 8.Outside gasbag plug 1
Side is provided with asbestos layer 6, so both ensure that the compactness of filling, prevents the high temperature of polluter aiutage again.Gasbag plug 1 He
Be provided with cock cap 3 longitudinal run through endoporus 2 crack 7, cracking 7 is communicated with endoporus 2, so that whole thieff hatch Inflation plug is permissible
Push aside, conveniently pack into the barral of a gun (referring to Fig. 2) of sampling gun 10.
It is provided with inflator pump 4, the inflation inlet of inflator pump 4 is connected with the air cavity 8 in gasbag plug 1 in cock cap 3.Start inflator pump
4, air cavity 8 can be inflated.Cock cap 3 side is additionally provided with venting plug 5, to exit to air cavity 8.
As shown in Fig. 2 when sampling monitoring is carried out to polluter aiutage 11, push aside and crack 7, by the barral of a gun set of sampling gun 10
Enter endoporus 2, gasbag plug 1 is stretched out in barral of a gun front end, gasbag plug 1 is inserted thieff hatch 9, cock cap 3 is outside thieff hatch 2.By sampling gun
After 10 are adjusted to correct position, start inflator pump 4, inflate to air cavity 8, gasbag plug 1 expands, by between sampling gun 10 and thieff hatch 9
Gap is all airtight, prevent gas leak phenomenon it is ensured that Monitoring Data accurate.
