Abstract

The utility model discloses an exhaust gas sampling gun accessory for sealing a sampling port, which comprises a sampling head, a base, a filter membrane, a supporting net and a sealing ring, wherein the sampling head comprises a sampling nozzle and a bent pipe, the sampling nozzle is coated with a plastic sleeve and can be taken off when in use, the sampling head, the bent pipe and the base are of an integrated structure, the interior of the sampling head, the bent pipe and the base are in a hollow state, the lower end of the base is sequentially overlapped with the filter membrane, the supporting net and the sealing ring, and the filter membrane and the supporting net can be clamped below the base by the sealing ring. The waste gas sampling gun accessory disclosed by the utility model is simple in structure and reasonable in design, is provided with the filter membrane and the supporting net, and is strong in practicability, when sampling is carried out, after waste gas flows through the sampling head and the base, particulate matters in waste gas are precipitated on the filter membrane, so that the particulate matters in the waste gas can be conveniently, qualitatively and quantitatively detected.

Description

Waste gas sampling gun accessory for sealing sampling port

Technical Field

The utility model relates to the technical field of sampling gun accessories, in particular to a waste gas sampling gun accessory for sealing a sampling port.

Background

Waste gas sampling is an important link of pollutant emission, equipment performance test and environmental protection supervision. The sampling of the waste gas mainly comprises sampling of the temperature, the flow rate, the mass concentration of particulate matters, the humidity and the components of the waste gas, and the existing sampling device basically only samples one or more waste gas parameters; and contain more dust particulate matter in the waste gas, these particulate matters need sample equally, but, present sampling rifle is difficult to collect the particulate matter at present, and then can't carry out ration, qualitative detection to dust particulate matter.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides an exhaust gas sampling gun accessory for sealing a sampling port.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a waste gas sampling rifle accessory for sample connection is sealed, includes sampling head, base, filter membrane, holds in the palm net and sealed lasso, the sampling head includes sampling mouth and return bend, the cladding has the plastic cover on the sampling mouth, plucks during the use can, sampling head, return bend and base formula structure as an organic whole, inside are the cavity state, the lower extreme of base coincide in proper order is equipped with the filter membrane, holds in the palm net and sealed lasso, sealed lasso can be with the filter membrane with hold in the palm the below of net card at the base.

The above-mentioned a waste gas sampling rifle accessory for sampling port is sealed, the support net adopts stainless steel material preparation to form.

The waste gas sampling gun accessory for sealing the sampling port is characterized in that the sampling head and the base are made of a metal titanium material.

The above waste gas sampling gun fitting for sealing the sampling port is characterized in that the sealing ring is made of a metal aluminum material.

The above-mentioned waste gas sampling rifle accessory for sampling mouth is sealed, the sampling mouth is towards the horizontal direction.

Compared with the prior art, the utility model has the following advantages and prominent effects:

the waste gas sampling gun accessory has the beneficial effects that the structure is simple, the design is reasonable, the filter membrane and the supporting net are arranged, when in sampling, after waste gas flows through the sampling head and the base, particulate matters in waste gas are precipitated on the filter membrane, the qualitative and quantitative detection of the particulate matters in the waste gas is convenient, and the practicability is high.
