Description
Technical field
The utility model relates to a kind of air chamber structures of gas analyzer.
Background technique
It is sheet metal chassis in current gas analyzer, gas chamber is installed in the chassis, and gas sensor is mounted on gas
In room, sensor is easily-consumed products, when a sensor is replaced, it is necessary to first open cabinet, then open gas chamber, it is necessary to just using tool
Row, makes troubles to operator.
Utility model content
The utility model aim is to provide a kind of air chamber structure of gas analyzer in view of the defects existing in the prior art.
The utility model to achieve the above object, adopts the following technical scheme that a kind of air chamber structure of gas analyzer, packet
Air chamber base made of including with upper cover and lower cover, the air chamber base are provided with air inlet in the side for being located at the upper cover,
The other side positioned at the upper cover is provided with gas outlet；Air flue, the lower cover middle part are formed between the air inlet and air outlet
The saddle being equipped with, the saddle top are matched with the center mounting hole being provided on upper lid, and the has been crossed in the middle part of the saddle
One through-hole, the first through hole and the air flue connection are being provided with sensor, the sensing at air flue on the saddle
The second through-hole with the first through hole connection is offered on the bottom saddle of device.
Further, the outer rim of the air chamber base is with threaded hole, and is fixed by screws on cabinet.
Further, the built-in small O-ring of the lower cover upper slot, the lower cover lower channel is interior to be equipped with big O-ring.
The utility model has the beneficial effects that the utility model can not have to tool changing sensor, personnel behaviour is maintained easily
Make,
Machined part is few, and structure is simple.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Shown in Fig. 1, be related to a kind of air chamber structure of gas analyzer, including with upper cover 2 and lower cover 6 made of gas chamber
Seat 1, the air chamber base 1 are provided with air inlet in the side for being located at the upper cover 2, are arranged in the other side for being located at the upper cover 2
There is gas outlet；Form air flue between the air inlet and air outlet, the saddle 7 being equipped in the middle part of the lower cover 6, on the saddle 7
Portion is matched with the center mounting hole being provided in upper cover 2, and first through hole, the first through hole have been crossed in the middle part of the saddle 7
With the air flue connection, sensor 3 is being provided at air flue on the saddle 7, on the bottom saddle 7 of the sensor 3
Offer the second through-hole with the first through hole connection.
When work, gas is entered by the air inlet of air chamber base 1, reaches sensor 3 by 6 centre bore of lower cover, then from gas chamber
The gas outlet outflow of seat 1,1 air inlet of air chamber base and gas outlet are threaded hole.Sensor 3 is clipped between upper cover 2 and lower cover 6,
The connecting line of sensor 3 is drawn from the centre bore of upper cover 2.The built-in small O-ring 4 of 6 upper slot of lower cover, its underpart slot are built-in big O-shaped
Circle 5 guarantees air chamber sealing.When needing replacing sensor, lower cover only need to be unscrewed with hand, finger is put in gas chamber, pulls up sensing
Then device plugs new sensor, tighten lower cover, achievees the purpose that quick-replaceable sensor.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
