Abstract
The utility model provides a gas sampling device, which comprises a gas analyzer, a hollow telescopic rod, a soft pipe and a filtering device, wherein the soft pipe is arranged in the telescopic rod, the end of the soft pipe is connected with the gas analyzer, the filtering device is arranged at the front end portion of the telescopic rod, and the front end of the soft pipe is connected with the filtering device. The gas sampling device adopts a mode that the telescopic rod is sleeved on the soft pipe, thereby shortening sampling time, reducing outside influences on gas samples and avoiding gas sample pollution. The gas sampling device has the advantages of being adjustable in length and convenient to detect and carry and having good detecting effect.
Description
Technical field
The utility model relates to a kind of gas sampling assembly, belongs to field of gas detection.
Background technology
In the gas detection industry, under a lot of situations, the testing staff will carry out gas sampling by detecting feeler lever, its drawback is to detect weak point and fixing of distance, also is inconvenient to carry, simultaneously, in the sampling process, the pipe interior space of detecting feeler lever is bigger, causes the sampling time elongated easily; Also have direct use expansion link to sample, but because there is the slit in expansion link at joint, easy gas with non-sampled point is introduced, thereby caused the pollution of sample gas.
For this reason, people are seeking a kind of desirable technical solution always.
Summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of easy to detect, easy to carry, detect effective gas sampling assembly.
The technical scheme that the utility model adopted is as follows: a kind of gas sampling assembly, it comprises expansion link, flexible pipe and the filtration unit of gas analyzer, hollow, described flexible pipe is arranged in the described expansion link, the end of described flexible pipe connects described gas analyzer, the leading section of described expansion link is installed described filtration unit, and the front end of described flexible pipe connects described filtration unit.
The utility model has substantive distinguishing features and progress with respect to prior art, specifically, this gas sampling assembly adopts the sample mode of interior suit flexible pipe of expansion link and expansion link front end dress filtration unit, make sampling convenient, sampling time shortens, sample gas is affected by the external environment little, and has avoided sample gas to pollute, have adjustable length, easy to detect, easy to carry, detect effective advantage.
Description of drawings
Fig. 1 is a sectional structure synoptic diagram of the present utility model.
Embodiment
In order to further specify the utility model, the existing embodiment that provides in conjunction with the accompanying drawings:
As shown in Figure 1, a kind of gas sampling assembly, it comprises expansion link 1, flexible pipe 2 and the filtration unit 3 of gas analyzer, hollow, described flexible pipe 2 is arranged in the described expansion link 1, the end of described flexible pipe 2 connects described gas analyzer, the leading section of described expansion link 1 is equipped with filtration unit 3, and the front end of described flexible pipe 2 connects described filtration unit 3;
Described expansion link 1 plays the effect of supporting flexible pipe 2, and its adjustable length is convenient to the detection of different distance, and is convenient for carrying; As required, the surface of expansion link 1 can be provided with the length scale; Flexible pipe 2 inner useful volumes are very little, and the sampling time can shorten greatly, and flexible pipe 2 leakproofnesss are very good, and the sampling location accurately and reliably; The filtration unit 3 of expansion link front end can filter out unwanted collection thing.
Specifically, flexible pipe 2 is penetrated in the expansion link 1, flexible pipe 2 front ends and expansion link 1 front end are fixed together, expansion link 2 front ends are installed filtration unit 3, the front end of flexible pipe 2 connects filtration unit 3, flexible pipe 2 ends are received on the gas analyzer, and gas analyzer can carry out gas analysis by the gas sample that flexible pipe 2 is taked; The whole process of sampling utilizes flexible pipe 2 to sample all the time; In the testing process, can be according to the length of the needs of actual detected distance control expansion link 1, expansion link 1 can soft 2 draws in outside the interior or push-off pin of bar in telescopic process.
This gas sampling assembly is mainly used in the grab sampling of gas, has overcome existing thief rod length and has fixed, detects the drawback that distance is short and be inconvenient to carry; This gas sampling assembly makes the sampling apparatus in the gas sampling course of work significantly reduce, and has improved integration.
Claims (1)
1. gas sampling assembly, comprise gas analyzer, it is characterized in that: this gas sampling assembly also comprises expansion link, flexible pipe and the filtration unit of hollow, described flexible pipe is arranged in the described expansion link, the end of described flexible pipe connects described gas analyzer, the leading section of described expansion link is installed described filtration unit, and the front end of described flexible pipe connects described filtration unit.
