Abstract
The utility model relates to an integrated type gas channel structure. The structure comprises a metal block which is arranged on a sensor, a gas chamber is arranged between the metal block and the sensor, a sealing ring is arranged on a contact surface between the metal block and the sensor on the periphery of the gas chamber, and a gas inlet hole and a gas outlet hole which are arranged in the metal block are communicated with the gas chamber. The integrated type gas channel structure has the advantages that the pipe-free connection is achieved, the gas tightness is good, the structure is compact, and the inside capacity is small.
Description
Technical field
The utility model relates to a kind of integrated form gas circuit structure.
Background technology
In the detection of the gas componant of packing container, gas arrives sensor through gas circuit structure in the sample.In legacy equipment, gas circuit structure is by flexible pipe each element to be coupled together.There is following shortcoming: 1, gas circuit structure more complicated.2, impermeability is relatively poor.3, internal volume is larger.
Summary of the invention
The purpose of this utility model provides a kind of integrated form gas circuit structure exactly for overcoming above problem, realizes connecting without pipe, and impermeability is good, compact conformation, and internal volume is little.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of integrated form gas circuit structure, it comprises a derby, and derby places on the sensor, is provided with air chamber between described derby and the sensor, between the surface of contact of air chamber periphery derby and sensor, be provided with O-ring seal, in derby, then be provided with air admission hole and venthole and be communicated with described air chamber.
Described air chamber is an interior concave space at sensor top, is the sensor sensing face in the bottom of this air chamber.
Described air chamber is an interior concave space at sensor top, is the sensor sensing face in the bottom of this air chamber, and the projection that matches with described interior concave space is arranged at described derby bottom, and described projection probes into described air chamber.
Characteristics of the present utility model are: 1, realize connecting without pipe.2, compact conformation, internal volume is little.3, impermeability is good.
Description of drawings
Fig. 1 is the structural drawing of integrated form gas circuit structure the first case study on implementation.
Fig. 2 is the structural drawing of integrated form gas circuit structure the second case study on implementation.
Wherein, 1. O-ring seal, 2. air admission hole, 3. air chamber, 4. venthole, 5. sensor sensing face, 6. sensor, 7. derby.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
Among Fig. 1, establish some air admission holes 2, venthole 4 in the derby 7.Derby 7 has sensor 6, and sensor 6 top indents form air chamber 3.Gas enters air chamber 3 through air admission hole 2, arrives the sensor sensing face 5 of sensor 6, is discharged by venthole 4.Between the surface of contact of air chamber 3 peripheral sensors 6 and derby 7, be provided with O-ring seal 1.
Embodiment 2:
Among Fig. 2, on the basis of embodiment 1, derby 7 makes down " protruding " shape into.Extend in the air chamber 3.
