Description
Technical field
The utility model belongs to exhaust gas sampling technique field, and in particular to a kind of exhaust gas thieff hatch flexible closure device.
Background technique
In industrial waste gas exhaust tube pollution sources detection process, the sampling of exhaust gas in exhaust tube is needed on exhaust tube side wall
Thieff hatch is opened up, sample detecting is directly carried out by exhaust gas sampling gun, if thieff hatch is not dealt with, exhaust gas directly passes through sampling
Hole loss influences the health of operator.
Currently used closing mode is that matching pipeline is arranged on thieff hatch, and pipe end is connected by flange
Connects cover plate is sealed, this closing mode, and disassembly is inconvenient, and perishable, bad sealing causes gas leakage.
Summary of the invention
For the deficiency in the presence of the prior art, it is simple that the utility model provides a kind of structure, design rationally, corrosion resistant
Erosion is easy to use, seals strict exhaust gas thieff hatch flexible closure device.
The technical solution of the utility model are as follows: exhaust gas thieff hatch flexible closure device, including with thieff hatch shape size phase
Matched closed plate, the closed plate be corrosion-resistant elastic plate body structure, the surrounding of the closed plate be provided with for sampling
The card slot that the cylinder side wall of hole surrounding is connected.
The closed plate is circle plate body structure made of anti-corrosive rubber, and the card slot is to surround to be provided with the closing
The trapezoid groove structure of plate side.
Have in the closed plate from center radial joint-cutting around.
Angle between two adjacent joint-cuttings is 15 °.
Handle is provided in the closed plate.
The handle is centrally located in the closed plate, and the handle is semi-circular shape structure, the handle and institute
Closed plate is stated to link into an integrated entity structure.
The utility model has the beneficial effects that the utility model has the advantages of simple structure, low in cost, rationally, resistance to exhaust gas is rotten for design
Erosion, long service life, when use, are installed in thieff hatch, and it is convenient to operate, and card slot is bonded with the cylinder side wall of thieff hatch surrounding
Closely, sealing is tight, avoids exhaust leak.

Specific embodiment
Specific embodiment of the present utility model is further described with reference to the accompanying drawings and embodiments, is implemented below
Example is used to more clearly describe the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
Embodiment 1: as shown in Figure 1-3, exhaust gas thieff hatch flexible closure device, including match with thieff hatch shape size
Closed plate 1, closed plate 1 is corrosion-resistant elastic plate body structure, and the surrounding of closed plate 1 is provided with for the cylinder with thieff hatch surrounding
The card slot 2 that side wall is connected.
In the above-described embodiments, thieff hatch is to be provided with the circular through hole that diameter is 8-10cm on vertical exhaust tube, closing
Plate 1 is circle plate body structure made of the anti-corrosive rubber material that matches with thieff hatch, and card slot 2 is around being provided with closed plate
The trapezoid groove structure of 1 side.As shown in figure 4, card slot 2 is connected together with cylinder side wall 5.The groove width of card slot 2 from inside to outside is successively
Increase, cylinder side wall 5 is caught in card slot 2 when use, while 2 inner sidewall of card slot is bonded closely with the external of cylinder side wall 5, it is close
It obturages close, avoids exhaust leak.When needing to sample, removes closed plate 1 and probe into exhaust gas sampling gun in thieff hatch and sampled i.e.
Can, after sampling, closed plate 1 is reinstalled into thieff hatch.
Embodiment 2: measuring to probe into exhaust gas sampling gun in exhaust tube in the state of not removing closed plate 1,
The convenience for promoting measurement is opened up from its center in closed plate 1 and is in around as shown in figure 5, on the basis of embodiment 1
Radial joint-cutting 4.Exhaust gas sampling gun is probeed by the center of closed plate 1 when measurement, and shape occurs for 1 ontology of closed plate at joint-cutting 4
Change is probeed into for exhaust gas sampling gun, and sampling finishes, and exhaust gas sampling gun is extracted out from the center of closed plate 1, closed plate 1 at joint-cutting 4
Body restores deformation, restores sealing state.Further, the angle between two adjacent joint-cuttings 4 is 15 °, in closed plate 1 from its
Center is radial around to be uniformly provided with 24 joint-cuttings 4, and good appearance enters convenient for exhaust gas sampling gun.
Embodiment 3: in order to be convenient for removing closed plate 1 out of thieff hatch in sampling, as shown in Figures 6 and 7, in closed plate
Handle 3 is provided on 1.Further, handle 3 is centrally located in closed plate 1, handle 3 be semi-circular shape structure, handle 3 with
Closed plate 1 links into an integrated entity structure.When removing sampling plate 1, closed plate 1 can be removed out of thieff hatch with hand grip handle 3.
