the vertical valve is communicated in series on a pipeline from the air filter to the sampling machine;
and the transverse valve is communicated with a communicating pipeline from the air filter to the vertical valve in parallel.
Through the technical scheme, through the two added valves, the vertical valve is opened and the transverse valve is closed during normal use, so that the sampling tube can be normally communicated with the sampling tube; when the vertical valve is closed and the transverse valve is opened during maintenance, air is blown or sucked to the transverse valve for cleaning, and the used cleaning medium cannot flow to the sampler because of the closing of the vertical valve, so that the damage of the sampler is avoided.
Further, a purging hose is further arranged on the transverse valve.
Through above-mentioned technical scheme, set up the hose of blowing convenient to use person is convenient for with cleaning equipment from a plurality of angles, high intercommunication transverse valve under the circumstances such as narrow and small space.
Further, the device also comprises a three-way pipe, wherein the sampling pipe, the vertical valve and the transverse valve are mutually communicated through the three-way pipe.
Through above-mentioned technical scheme, the connected mode of three-way pipe can increase of service life effectively, when avoiding filling into cleaning medium in the transverse valve, is erodeed by medium for a long time and leads to the body wearing and tearing big, only need the new three-way pipe of renewing can when later maintenance.
Furthermore, a capillary sampling point and a tributary sampling point are connected in parallel on a pipeline from the multifunctional sampling point to the tail end of the sampling pipe.
Through the technical scheme, the parallel capillary is a high-precision and high-sensitivity sampling technology, and is generally used for detecting low-concentration harmful gases, volatile organic compounds and the like. These substances are very small in air, even at a concentration of only one part per billion, and therefore require the use of high-sensitivity quality analysis instruments to be able to accurately determine; the parallel branch sampling point pipes are mainly used for simultaneously collecting air samples at different positions and directions, so that the pollution and harmful substance content in the surrounding environment can be comprehensively and accurately known.
In summary, the present utility model includes at least one of the following beneficial technical effects:
(1) Through the added two valves, the vertical valve is opened and the transverse valve is closed during normal use, so that the sampling tube can be normally communicated with the sampling tube; when the vertical valve is closed and the transverse valve is opened during maintenance, air is blown or sucked to the transverse valve for cleaning, and the used medium for cleaning cannot flow to the sampler because of the closing of the vertical valve, so that the damage of the sampler is avoided;
(2) The transverse valve is also provided with a purging hose; the air blowing hose is convenient for a user to communicate the cleaning device with the transverse valve from a plurality of angles and heights under the conditions of narrow space and the like.
