Description

Volatile organic gas diffusion sampling pipe

Technical Field

The utility model relates to the technical field of gas sampling devices, in particular to a volatile organic gas diffusion sampling tube.

Background

After the gas sampling pipe is used for a single time, the gas sampling pipe needs to be cleaned, so that the problem that the gas residues collected at the last time are attached to the pipe wall to influence the subsequent detection is solved; the inlet end of current sampling pipe generally is less than the inner chamber of sampling pipe to the comparatively long and narrow body structural design of integral type, people of being not convenient for wash the inner wall of gas sampling pipe, and the clearance degree of difficulty is great relatively, wastes time and energy, and the practicality is relatively poor.

In view of the foregoing, there is a need for a volatile organic gas diffusion sampling tube that addresses the deficiencies in the prior art.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a volatile organic gas diffusion sampling tube, aiming at solving the problems.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a volatile organic gas diffusion sampling pipe, includes the body, the body is still including first nipple, second nipple, the both ends symmetry is equipped with the adapter sleeve about the body, the pipe cap is all installed through the adapter sleeve to first nipple and second nipple, first nipple is close to the fixed inner tube joint that is equipped with of one end at body middle part, the fixed outer tube joint that is equipped with of one end that the second nipple is close to the body middle part, first nipple and the inside of second nipple are all fixed and are equipped with the sampling and adsorb the chamber, the inside joint that the chamber was adsorbed in the sampling has the adsorption column.

Preferably, the connecting wall of the connecting sleeve and the pipe cap is also provided with a sealing ring.

Preferably, the first nipple is screwed to the outer nipple of the second nipple through an inner nipple.

Preferably, the inner diameters of the left and right ends of the body are the same.

Preferably, the circumference outer wall of adsorption column is equipped with the spacing strake of several, and the fixed limit groove of still having seted up adaptation in spacing strake of inner wall in sampling adsorption cavity, and the appearance structure of adsorption column is the cylindrical structure of adaptation in sampling adsorption cavity.

Preferably, a communicating cavity is fixedly arranged inside the inner pipe joint.

The utility model has the beneficial effects that: the connecting sleeve and the connecting wall of the pipe cap are provided with a sealing ring, the inner pipe joint of the first short connecting pipe is in threaded connection with the outer pipe joint of the second short connecting pipe, the combined assembly type using effect is achieved, the problem that cleaning is inconvenient due to a traditional long and narrow pipe body is avoided, the appearance structure of the adsorption column is a cylindrical structure which is adaptive to the sampling adsorption cavity, adaptation installation is facilitated, replacement and cleaning are convenient, practicability is high, and certain use value and popularization value are achieved.

Detailed Description

As shown in fig. 1, 2, 3, 4, a volatile organic gas diffusion sampling pipe, including body 1, body 1 is still including first nipple 2, second nipple 3, the both ends symmetry is equipped with adapter sleeve 4 about body 1, pipe cap 5 is all installed through adapter sleeve 4 to first nipple 2 and second nipple 3, first nipple 2 is close to the fixed inner tube joint 6 that is equipped with of one end at body 1 middle part, second nipple 3 is close to the fixed outer tube joint 7 that is equipped with of one end at body 1 middle part, first nipple 2 all is fixed with sampling adsorption cavity 8 with the inside of second nipple 3, the inside joint of sampling adsorption cavity 8 has adsorption column 9.

Furthermore, the connecting wall of the connecting sleeve 4 and the pipe cap 5 is also provided with a sealing ring.

Further, the first nipple 2 is screwed to the outer nipple 7 of the second nipple 3 through the inner nipple 6.

Further, the inner diameters of the left and right ends of the body 1 are the same.

Further, the circumference outer wall of adsorption column 9 is equipped with the spacing strake 91 of several, and the fixed limit groove 81 of still having seted up adaptation in spacing strake 91 of inner wall in sampling adsorption cavity 8, and the appearance structure of adsorption column 9 is the cylindrical structure of adaptation in sampling adsorption cavity 8.

Further, a communicating cavity is fixedly arranged inside the inner pipe joint 6.

The working principle of the utility model is as follows: after the single sampling is accomplished, when needing to wash body 1, twist out through the rotation of inner tube joint 6 with first nipple 2 and outer tube joint 7 of second nipple 3, then take out the adsorption column 9 that corresponds in first nipple 2 and the second nipple 3, carry out the segmentation clearance to first nipple 2 and second nipple 3 again after that, with this effect of playing combination assembled use, the inconvenient problem of clearance because of the long and narrow body of tradition has been avoided, and, the appearance structure of adsorption column 9 is the cylindrical structure of adaptation in sampling adsorption cavity 8, make things convenient for the adaptation installation, it is comparatively convenient to change the clearance, the practicality is stronger relatively.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
