Abstract
The utility model relates to an exhaust connector for analyzing atmosphere sample, one end of which is connected with a latex tube, and the other end is connected with a sampling pin case. A unidirectional inlet valve plate(1) is arranged on the end of the exhaust connector connected with the latex tube, and a unidirectional outlet valve plate(2) is arranged on an exhaust end. When sampling, the unidirectional inlet valve(1) is opened and the unidirectional outlet valve(2) is closed by pulling out a piston of the pin case, and gas in the latex tube enters the pin case; the unidirectional inlet valve(1) is closed and the unidirectional outlet valve(2) is opened by pushing the piston of the pin case forward, the gas in the pin case is exhausted. The gas in the latex tube is drained by repeating in the way for a plurality of times, and the required atmosphere sample is obtained.
Description
Affiliated technical field:
The present invention is mainly in petrochemical complex, and is used during domain analysis gas samples such as environment.
Background technology:
At present, analyze the tower that can not directly enter by personnel, still, closed container, during the medium gas componant content of inspection shaft, the emulsion tube that need connect certain-length with the syringe of sampling usefulness comes the extracting gases sample to analyze, during sampling in order to make gas sample representative, at first want the air in the emptying emulsion tube, during exhaust the other end of emulsion tube is put in the gas space that needs to analyze, extract a gas earlier, clutch the end that emulsion tube connects syringe with hand then and prevent that air from entering, take off syringe, air in the emptying syringe, reconnect emulsion tube and repeat above action, the air in the emptying emulsion tube is obtained the gas sample that needs analysis, will enter as pinching not tight emulsion tube air during exhaust, cause sampling inaccurate.
Summary of the invention:
Main body of the present invention is a kind of analytical gas sampling exhaust joint, and an end connects emulsion tube, and an end connects the sampling syringe.1. an end that connects emulsion tube is equipped with the breather cheek valve sheet; 2. one end of exhaust is equipped with unidirectionally gives vent to anger valve block.During sampling, extract cylinder piston, 1. breather cheek valve is opened, and 2. unidirectional air outlet valve cuts out, and gas enters in the syringe in the emulsion tube; Cylinder piston pushes away forward, and 1. the breather cheek valve sheet closes, and 2. the unidirectional valve block of giving vent to anger is opened, and the interior air of syringe is discharged, and so comes and goes for several times, but with regard to emptying latex inner air tube, obtains the gas that needs.
Embodiment:
Analytical gas sampling exhaust joint material is plastics, and air-intake valve plate and air outlet valve sheet material are rubber sheet, and 1. valve block is opened when extracting piston, and valve block is closed by suction function 2., and the air in the emulsion tube enters syringe; Before during push piston, 1. valve block is stressed and closes, 2. valve block is stressed and opens, the air in the syringe is discharged, and so come and go for several times, but emptying latex inner air tube is just obtained the gas sample that needs.
Beneficial effect:
After installing this joint during sampling, smoke a piston of pushing pin before and after only needing and just can obtain needs Sample is simple, convenient, accurate.
Description of drawings:
Shown in figure (), extract piston 3., 1. breather cheek valve is opened, and 2. unidirectional air outlet valve cuts out, and gas enters in the syringe in the emulsion tube; Before push piston 3., 1. the breather cheek valve sheet closes, 2. the unidirectional valve block of giving vent to anger is opened, the air in the syringe is discharged; So come and go for several times, but, obtain the gas sample that needs with regard to the 4. interior air of emptying emulsion tube.
Figure (two) is analytical gas sampling exhaust joint sectional view.
Claims (1)
1. the analytical gas sampling exhaust joint of using when an analytical gas is taken a sample is characterized in that an end connects emulsion tube, and an end connects the sampling syringe, and an end of connection emulsion tube is equipped with the breather cheek valve sheet, and an end of exhaust is equipped with the unidirectional valve block of giving vent to anger.
