Detailed Description
As shown in figure 1, a gas device is got to compression jar ration, including sampler 1 and the connecting device 2 of connecting compression jar and sampler 1, connecting device 2 is including connecting cavity 21 and connector 22, and connecting cavity 21 passes through connector 22 and is connected with the compression jar, and the end of giving vent to anger of connecting cavity 21 is equipped with the one-way portion 211 of giving vent to anger of elasticity that makes the gas in the connecting cavity 21 give vent to anger in one way, and the sampling syringe needle of sampler 1 runs through sealing member 24 and the connecting cavity 21 intercommunication on the connecting cavity 21 interlude.
In particular, the sampler 1 is a syringe.
As shown in fig. 2, the elastic one-way air outlet portion 211 comprises two curved flaps, the curved directions of the flaps are opposite to each other; the bottoms of the two valve clacks are respectively connected with the end part of the connecting cavity 21, the tops of the two valve clacks are attached together under the action of elasticity of materials, and the elastic one-way air outlet part 211 is made of rubber materials.
The middle section of connecting cavity 21 is equipped with outside convex open end 212, and sealing member 24 is connected with open end 212 is detachable, and sealing member 24 is the rubber buffer, can dismantle after once using and change the rubber buffer.
The connector 22 is provided with a check valve 23 for allowing the gas in the compression tank to flow into the connection chamber 21 in a single direction.
The operation of the device is described in detail below with reference to the drawings in the examples.
When a certain amount of standard gas is taken, the connecting device 2 is connected with the pressure reducing valve of the compression tank, the sampling needle of the sampler 1 is inserted into the rubber plug, so that the sampling needle enters the connecting cavity 21, at the moment, the end part of the elastic one-way air outlet part 211 is in a closed state under the action of the elastic rubber, the pressure reducing valve and the one-way valve 23 are opened, so that the gas in the compression tank continuously enters the connecting cavity 21 through the connecting tube head 22, the pressure in the connecting cavity 21 is increased, the originally closed two valve flaps are opened, the gas in the connecting cavity 21 is output outwards through the opened valve flaps, after a certain time, when the gas in the connecting cavity 21 is the gas in the compression tank, the sampler 1 is continuously pulled, so that the air in the sampler 1 is continuously discharged into the connecting cavity 21 to be replaced with the gas in the connecting cavity 21, and meanwhile, the gas in the compression tank is continuously supplemented to the gas in the connecting cavity, finally, the cavity of the needle of the sampler 1 is filled with gas in the compression tank, and the gas in the connection cavity 21 can be extracted as standard gas for measurement.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention should be included in the scope of the present invention.
