Abstract
The utility model discloses a device for sampling or measuring gas. The device comprises a first sampling tube and a second sampling tube, wherein the axial lines of the first sampling tube and the second sampling tube are parallel and the first sampling tube and the second sampling tube are fixedly assembled together, the front ends of the first sampling tube and the second sampling tube are insertion ends, the part of the insertion end of the second sampling tube, which is close to the first sampling tube, is aligned to the insertion end of the first sampling tube, the end surface of the insertion end of the first sampling tube is a horizontal plane vertical to the axial line of the first sampling tube, the end surface of the insertion end of the second sampling tube is an inclined plane which is aslant crossed with the axial line of the second sampling tube, and the part of the inclined plane, which is close the first sampling tube, is arranged on the front of the part which is far away from the first sampling tube. When air flows in a fluid pipeline, the flow rate of the air in the fluid pipeline to be measured can be calculated through measuring the differential pressure between the first sampling tube and the second sampling tube, and then the quantity of flow of the air in the fluid pipeline can be obtained.
Description
Technical field
The utility model relates to the sampling and measuring that a kind of gas that is used for the convection cell pipeline carries out flow measurement or sampling operation and uses plug assembly.
Background technology
At present the instrumentations that adopt carry out sampling operation or flow measurement to the gas in the pipeline more in the fluid circuit, and these instruments are more complicated all generally, make and use cost higher.And these instruments scarcely are fit to be applied in some like the abominable place that dust content is high, humidity is bigger, and it is of limited application, and use inconvenient.
The utility model content
The purpose of the utility model is to provide a kind of device that is used for gas sample or measurement simple in structure, easy to use.
For realizing above-mentioned purpose; The device that is used for gas sample or measurement that the utility model provided adopts following technical scheme: a kind of device that is used for gas sample or measurement; Comprise first stopple coupon and second stopple coupon; First stopple coupon and second stopple coupon parallel axes ground fixedly are assembled together side by side; The front end of first stopple coupon and second stopple coupon is insertion end, the insertion end of second stopple coupon near the part of first stopple coupon and the insertion end flush of first stopple coupon, the insertion end end face of first stopple coupon is the surface level perpendicular to self axis; The insertion end end face of second stopple coupon is and self crossing dip plane of axis tilt that the part near first stopple coupon of this dip plane is positioned at the place ahead away from the part of first stopple coupon.
Rear end on described first, second stopple coupon is a stiff end; The stiff end flush of first, second stopple coupon; First, second stopple coupon fixedly is assembled together through web member; The welding of the stiff end of this web member and said first, second stopple coupon is fixing, second opening that on web member, offers first-class through hole that the inner chamber with first stopple coupon is docked and connected and be docked and connected with the inner chamber of second stopple coupon.
The beneficial effect of the utility model is: when the plug assembly that the utility model provided uses; In the radially insertion fluid circuit with the insertion end longshore current body pipeline of first, second stopple coupon; The end face of the insertion end of such first stopple coupon is parallel with the airflow direction in the fluid circuit; The dip plane of the insertion end of second stopple coupon is air-flow dorsad; When in the fluid circuit gas flow being arranged, just can obtain the gas flow rate in the fluid circuit to be measured through the pressure reduction that calculates between first stopple coupon and second stopple coupon, and then can obtain the flow of gas in the fluid circuit.In addition; The gas that utilizes the pressure reduction between first stopple coupon and second stopple coupon to can also be used in the convection cell pipeline is taken a sample; Because stopple coupon is not easy to be stopped up by foreign material such as dust, so this mode of utilizing stopple coupon to come gas is taken a sample can be applied in the comparatively abominable workplace of environment as dust content is high, humidity is bigger.
