Abstract
A cylindrical positive pressure sampler for a gas detection tube relates to the technical field of gas sampler structures. The hand-operated automatic valve comprises a circular cylinder, wherein the front end of the circular cylinder is connected with an air nozzle through a manual ball valve, a piston is arranged in the circular cylinder, a pull rod is fixedly connected to the center of the piston, and the outer end of the pull rod is connected with a handle. During sampling, the manual ball valve is manually opened, the air nozzle is communicated with the circular cylinder, the handle is pushed inwards, and the piston is located at the foremost end of the circular cylinder. The air tap is aligned with the air source, the handle is pulled outwards to drive the piston to move towards the rear end of the circular cylinder body, pulling is stopped, and the manual ball valve is closed manually. And then the sampling tube is butted with the air tap, the manual ball valve is opened, the handle is pushed inwards, so that the gas in the circular cylinder is injected into the sampling tube, and the sampling is finished.
Description
Technical field
The utility model relates to the sampler structure technology of gas.
Background technology
In order to understand the accurate content of each composition in the gas, earlier gas to be sampled, sample gas is encapsulated in the stopple coupon, analyze through gas analyzer.Adopt the suction type sampling in the sampling in the past, instability, sampled concentrations is low.
The utility model content
The utility model purpose is to design a kind of that can overcome above defective and the supporting cylinder-shaped positive-pressure sampling instrument of gas detecting tube.
The utility model comprises a circular cylinder body, and the front end of circular cylinder body connects a valve by manual ball valve, arranges a piston in the circular cylinder body, connects a pull bar in the center fixation of piston, and the outer end of pull bar connects one handle.
During sampling, the manual unlocking manual ball valve makes valve be communicated with circular cylinder body, and inwardly driving handle makes piston be positioned at circular cylinder body foremost.Valve is aimed at source of the gas, and outwards the pull handle drives the back end motion of piston to circular cylinder body, stops pull, the manual-lock manual ball valve.Stopple coupon is docked with valve again, open manual ball valve, inwardly driving handle makes gas injection stopple coupon in the circular cylinder body, and sampling finishes.
The utility model is easy and simple to handle, and accountability is good, may sample to multiple gases.Be applicable under the coal mine, metallurgy, chemical industry, coking, gas station, tunnel engineering, environmental protection and health and epidemic prevention department, all gases concentration such as carbon monoxide, carbon dioxide, sulfuretted hydrogen, sulphuric dioxide, nitrogen dioxide, nitrogen, nitrogen, hydrogen in the fast measuring site environment.
For metering directly perceived, the utility model also is provided with volume evenly divided line on pull bar.
In addition, for enhanced leaktightness, described ball valve is connected with circular cylinder body by packing ring.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the front end of the utility model circular cylinder body 9 connects manual ball valve 4 by packing ring 7, and the other end of manual ball valve 4 connects a valve 2.5 is the switch knob of manual ball valve 4.The rear end of circular cylinder body 9 is connected with the cover 10 at center.
Arrange pistons 7 in the circular cylinder body 9, connect a pull bar 8 in the center fixation of piston 7, the outer end of pull bar 8 connects one handle 11, and volume evenly divided line 12 is set on pull bar 8.
Claims (3)
1, cylinder-shaped positive-pressure sampling instrument for gas detection tube, it is characterized in that comprising a circular cylinder body, the front end of circular cylinder body connects a valve by manual ball valve, arranges a piston in the circular cylinder body, center fixation at piston connects a pull bar, and the outer end of pull bar connects one handle.
2,, it is characterized in that on pull bar, being provided with volume evenly divided line according to the described cylinder-shaped positive-pressure sampling instrument for gas detection tube of claim 1.
