Abstract
The utility model belongs to the field of environmental monitoring instruments and equipment, and in particular relates to a flue gas sampling tube which comprises a tube body (1), wherein a sampling tube head (2) is arranged at the top of the tube body (1) and comprises a sampling nozzle (21) and a cup-shaped body (22) in which a glass fiber filtering cartridge (3) is stored. The flue gas sampling tube is characterized in that a concave (4) is horizontally formed in a cup opening of the cup-shaped body (22) along the inner wall of the cup-shaped body (21); a split-type arc-shaped metal gasket (5) is arranged in the concave (4); the shape and the size of the metal gasket (5) are the same as those of the concave (4). The flue gas sampling tube has the advantages of reasonable design and practical function. The glass fiber filtering cartridge is conveniently separated from the sampling tube.
Description
Technical field
The utility model belongs to environment supervision instrument apparatus field, particularly a kind of flue gas sampling pipe.
Background technology
The Lao that present environmental protection department at different levels is mostly used Qingdao LaoShan Application Technology Research Institute to produce answers the automatic flue dust of 3012H type (gas) tester and sampling pipe.Filter cylinder adopts the glass fiber filter cylinder supporting with sampling pipe bore.In prior art, sample tube head as shown in Figure 2, comprise sampling mouth (21) and goblet (22), goblet (22) interior placing glass fiber filter cylinder (3).There is following shortcoming in such sampling tube head: after hot and humid degree environment down-sampling, glass fiber filter cylinder easily sticks together with hypanthial opening part, when glass fiber filter cylinder is separated with goblet with tweezers, segment glass fiber filter cylinder can be poked the rear sticky tube wall of staying sampling pipe, causes monitoring misalignment.
In prior art, be to tear with tweezers, the application point of power is less, and glass fiber filter cylinder is easily torn.This programme is by after metallic gasket elastic deformation several times, with tweezers, insert the breach of metallic gasket end, with tweezers, to hypanthial center, press, the edge of the whole end of metallic gasket is to the strong effect of glass fiber filter cylinder, not only easily that glass fiber filter cylinder is separated with sampling pipe, and glass fiber filter cylinder is difficult for broken.
As another kind, improve, described metallic gasket is a complete torus.
Metallic gasket is a complete torus, and correspondingly depression is also a complete torus, and this scheme facilitates processing and manufacturing.
In sum, the utlity model has advantage reasonable in design, practical function, can easily glass fiber filter cylinder and sampling pipe be separated.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of flue gas sampling pipe is provided, and after hot and humid degree environment down-sampling, conveniently realizes the separated of glass fiber filter cylinder and sampling pipe.
To achieve these goals, the technical solution of the utility model is as follows: a kind of flue gas sampling pipe, comprise body, the top of body is sampling tube head, and sampling tube head comprises sampling mouth and for the goblet of placing glass fiber filter cylinder, described hypanthial rim of a cup place has been horizontally disposed with depression, depression is offered along hypanthial inwall, the metallic gasket that has a split type setting in depression, metallic gasket is circular arc, the shape of the shape of metallic gasket, size and depression, in the same size.
Metallic gasket is put into after depression, and it is level and smooth that goblet inwall keeps.After sampling, if find that glass fiber filter cylinder has been bonded at the opening part of sampling pipe, can insert between the outer wall and hypanthial inwall of metallic gasket with tweezers, with tweezers, to hypanthial center, press, make metallic gasket produce distortion, decontrol afterwards tweezers, metallic gasket restores to the original state, and this process can be shaken the adhesion between loose glass fiber filter cylinder and sampling pipe.
As improvement, the some breach of described hypanthial rim of a cup edge, metallic gasket is put into after depression, and the outer wall of metallic gasket touch breach.
Breach Convenient tweezers inserts between the outer wall and hypanthial inwall of metallic gasket.
As improvement, described metallic gasket has 2 ends, and the angle of the circle center line connecting of 2 ends and metallic gasket is less than 90 degree, and respectively there is a breach end of described metallic gasket.
