Abstract
A kind of infrared combusible gas probe calibration mask is the utility model is related to, including is installed on the case of the housing both sides of infrared combusible gas probe；It is characterized in that：The case of the both sides and the housing of infrared combusible gas probe surround to form closed chamber；The case of the both sides includes outer cover and inner cover, and sealing ring is set between outer cover and inner cover；Air inlet and exhaust outlet with closed chamber is set respectively on the case of the both sides, gladhand is set respectively in air inlet and exhaust ports.The infrared combusible gas probe calibration mask barrel cover volume-diminished, venthole becomes big and reduces the marked gas traffic requirement for being passed through barrel cover, and solves the problems, such as sealing shortcoming.
Description
Technical field
A kind of calibration mask is the utility model is related to, especially a kind of infrared combusible gas probe calibration mask.
Background technology
Existing infrared combusible gas probe calibration mask is divided into two parts, is barrel cover part and to enter gas shift connector portions
Point, acted on respectively to provide simulation gaseous environment and be passed through marked gas entrance.Existing infrared combusible gas probe mark
Technical problem existing for fixed cover has at 3 points.
1. barrel cover volume is big, therefore in calibration process, loss gas is big.
2. venthole is too small so that the calibration process time is elongated while the marked gas traffic requirement to being passed through barrel cover is high.
3. the sealing shortcoming of barrel cover so that the simulation gaseous environment that infrared gas detector calibration mask provides is present can not
Control and destabilizing factor are present.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of infrared combusible gas probe
Calibration mask, barrel cover volume-diminished, venthole becomes big and reduces the marked gas traffic requirement for being passed through barrel cover, and solves sealing and owe
The problem of lacking.
According to technical scheme provided by the utility model, the infrared combusible gas probe calibration mask, including be installed on
The case of the housing both sides of infrared combusible gas probe；It is characterized in that：The case of the both sides and infrared combustible gas detecting
The housing of device surrounds to form closed chamber；The case of the both sides includes outer cover and inner cover, is set between outer cover and inner cover
Sealing ring；Air inlet and exhaust outlet with closed chamber is set respectively on the case of the both sides, in air inlet and
Exhaust ports set gladhand respectively.
Further, the outer cover and inner cover are in circular arc type, and the arc length and height of outer cover are all higher than inner cover.
Further, groove is provided between the outer cover and inner cover, sealing ring is provided with groove.
Further, the outer cover is provided with screwed hole, and inner cover is provided with through hole, screwed hole be connected with through hole to be formed into
Gas port and exhaust outlet.
Further, the exhaust outlet and air inlet are separately positioned on the both sides of the upper and lower side of case, exhaust outlet and air inlet
The end face of line and case between mouthful is in more than 45 degree of angles.
Further, the gladhand connection PU flexible pipes.
Infrared combusible gas probe calibration mask described in the utility model realizes the calibration demarcation of diffusion type detection device, no
But it is simple in construction, and demarcation gas circuit is reasonable, facilitates Demarcate Gas；Calibration mask small volume, outlet bore dia are moderate, and sealing increases
By force, possesses the advantages of marked gas loss is small, demarcation condition requires more controllable low and environment and stabilization.

Embodiment
With reference to specific accompanying drawing, the utility model is described in further detail.
As Figure 1-5：The infrared combusible gas probe calibration mask includes infrared combusible gas probe 1, sealing
Circle 2, gladhand 3, case 4, outer cover 5, inner cover 6, groove 7, screwed hole 8, through hole 9, air inlet 10, exhaust outlet 11 etc..
As shown in figure 1, the utility model includes being installed on two structure identicals of the both sides of infrared combusible gas probe 1
Case 4, the case 4 of both sides and the housing of infrared combusible gas probe 1 surround to form closed chamber；As in Figure 2-4, institute
Stating the case 4 of both sides includes outer cover 5 and inner cover 6, and the outer cover 5 and inner cover 6 are in circular arc type, the arc length and height of outer cover 5
Inner cover 6 is all higher than, groove 7 is provided between outer cover 5 and inner cover 6, the sealing rings 2 of Ф 5 are provided with groove 7；It is as shown in figure 5, described outer
Cover 5 is provided with screwed hole 8, and inner cover 6 is provided with through hole 9, and screwed hole 8 is connected to form air inlet 10 and exhaust outlet 11 with through hole 9；
Installation gladhand 3 in the screwed hole 8, exhaust outlet 11 and air inlet 10 are separately positioned on the two of the upper and lower side of case 4
Side, the end face of line and case 4 between exhaust outlet 11 and air inlet 10 is in more than 45 degree of angles；The gladhand 3 connects
The PU flexible pipes of PT1/8- Ф 6 are connect, are used for exhaust or air inlet.
Operation principle and the course of work of the present utility model：As shown in figure 1, marked gas passes through the PU flexible pipes of PT1/8- Ф 6
Enter from air inlet 10 in cover, discharged after detection from exhaust outlet 11；Line and case 4 between exhaust outlet 11 and air inlet 10
End face is in more than 45 degree of angles, to increase marked gas gas circuit length, increases the detection recognition efficiency of infrared combusible gas probe.
