Description

Technical Field

[0001] The utility model relates to the technical field of gas sampling, in particular to a product sample gas analysis sampling mechanism. Background Art

[0002] Industrial gases are known as the "blood" of industry.

[0003] Gas analysis is an analytical method that uses the different physical and chemical properties of various gases to determine the composition of mixed gases. In order to ensure normal and safe production in industrial production, various industrial gases must be analyzed to understand their composition.

[0004] During the use of the existing gas sampling device, since the sample container originally contains gas components from other areas, the original gas in the sample container mixes with the sampled gas during the sampling process, resulting in impure sampled gas, which affects subsequent detection results.

[0005] For this reason, we propose a product sample gas analysis sampling mechanism to solve the existing problems. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and proposes a product gas sample analysis sampling mechanism.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a product sample gas analysis sampling mechanism, comprising a cylinder, a collecting tank, a frame, a connecting pipe and a piston, a piston being slidably installed in the cylinder, a connecting pipe and an air inlet pipe being provided on the cylinder, the collecting tank being installed at the bottom end of the connecting pipe, and a valve structure being provided on the collecting tank, the connecting pipe and the air inlet pipe.

[0008] Preferably, a slide bar is installed on the end surface of the piston, and a rack is installed on the slide bar through bolts;

[0009] The outer wall of the cylinder is mounted on a frame by bolts, a gear is rotatably mounted on the frame, and the gear and the rack are meshed with each other;

[0010] The frame is provided with mounting holes.

[0011] Preferably, a third valve is installed at the connection position between the air inlet pipe and the cylinder;

[0012] A mounting head is installed at the opening of the collection tank, and the mounting head is threadedly mounted on the bottom end of the inner wall of the connecting pipe;

[0013] A second valve is installed at the connection position between the bottom end of the mounting head and the collection tank;

[0014] A first valve is installed at the connection position between the connecting pipe and the cylinder.

[0015] Preferably, the outer surface of the frame is mounted with a chassis by bolts;

[0016] A motor is installed in the chassis by bolts, and the output end of the motor is connected to the shaft end of the gear.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] During use, the product gas sample analysis sampling mechanism of the utility model can be fixed on the product production station through the mounting hole. At this time, the piston is at the lowest end of the cylinder. When it is necessary to sample the product gas sample, the air inlet pipe is closed through the valve structure, and the connecting pipe and the collection tank are opened;

[0019] Connect an external power source so that the power device drives the gear to rotate, and the meshing action between the gear and the rack causes the slide rod to drive the piston to move. At this time, the air in the collection tank is pumped into the cylinder, making the inside of the collection tank a negative pressure state. Then close the connecting pipe, and then open the air intake pipe to control the movement of the piston to squeeze out the air inside the cylinder.

[0020] At this time, open the control valves of the connecting pipe and the collecting tank, and then control the piston to move through the air inlet pipe to suck the product sample gas at the designated position. The sucked air enters the collecting tank under the action of negative pressure, and then close the control valve of the collecting tank and remove the collecting tank from the connecting pipe.

[0021] The utility model can discharge the gas components originally contained in the sample storage container before sampling, so as to avoid the sampled gas being impure and improve the accuracy of subsequent detection results. BRIEF DESCRIPTION OF THE DRAWINGS
