Abstract
The utility model provides a sampling pipe, comprising a sample pipe and sample pipe caps located at the two ends of the sample pipe, which is characterized in that sealing pistons extending into the sample pipe are arranged in the sample pipe caps, and seals are arranged in the seal grooves around the sample pipes. The utility model has excellent sealing effect and security.
Description
Technical field:
The utility model is relevant with analytical instrument, special be used for atmospheric sample collection and effective that the sample sampling pipe of its protection is relevant.
Background technology:
In analysis field, the security of sample is crucial, and the time domain of sample is also very strong, and particularly atmosphere is gathered all the more so.Traditional sample sampling pipe is made up of sample hose that is filled with sorbing material and sample pipe cap.Only depend on the O type circle sealing that is arranged in the sample pipe cap.Internal gas expands when the sample hose temperature raises, and is easy to generate leakage, causes sample loss.
The utility model content:
The purpose of this utility model is in order to overcome with deficiency, to provide a kind of sealing effectiveness good, the sample sampling pipe of safety.
The purpose of this utility model is achieved like this:
The utility model is the improvement on the basis of existing sample sampling pipe, comprise sample hose, lay respectively at the sample pipe cap at sample hose two ends, it is characterized in that the packed-piston that stretches into the sample hose mouth of pipe is arranged in the sample pipe cap, the seal groove that is arranged in the sample hose periphery is equipped with sealing.
The packed-piston and the sample hose mouth of pipe in the above-mentioned sample pipe cap are interference fit, and sealing effectiveness is good.
Above-mentioned sample hose mouth of pipe end face is the inclined-plane, and the inclined-plane that cooperates with sample hose mouth of pipe inclined-plane is arranged in the sample pipe cap, and sealing effectiveness is better.
When using the utility model, filling adsorption material in sample hose.When sample hose is finished sampling insertion sample pipe cap, just form piston and sample hose, sample hose mouth of pipe end face and sample pipe cap inclined-plane and seal three hermetic units, guaranteed the security of sample effectively.
The utility model is simple in structure, and sealing effectiveness is good, safety.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is a sample hose cap synoptic diagram.
Embodiment:
Referring to Fig. 1, Fig. 2, present embodiment sample sampling pipe comprises the sample hose 2 that is filled with sorbing material 1, lays respectively at the sample pipe cap 3 at sample hose two ends.Have in the sample pipe cap that to stretch in the sample hose mouth of pipe with the sample hose mouth of pipe be the packed-piston 4 of interference fit.The seal groove 5 that is arranged in the sample hose periphery is equipped with O RunddichtringO 6.Sample hose mouth of pipe end face 7 is the inclined-plane, and the inclined-plane 8 that cooperates with sample hose mouth of pipe inclined-plane is arranged in the sample pipe cap.
Claims (3)
1, the sample sampling pipe comprises sample hose, lays respectively at the sample pipe cap at sample hose two ends, it is characterized in that the packed-piston that stretches into the sample hose mouth of pipe is arranged in the sample pipe cap, and the seal groove that is arranged in the sample hose periphery is equipped with sealing.
2, sample sampling pipe as claimed in claim 1 is characterized in that the packed-piston and the sample hose mouth of pipe in the sample pipe cap is interference fit.
3, sample sampling pipe as claimed in claim 1 or 2 is characterized in that sample hose mouth of pipe end face is the inclined-plane, has the inclined-plane that cooperates with sample hose mouth of pipe inclined-plane in the sample pipe cap.
