Abstract

The purpose is a gas sampler consisting of a bottle, with a valve cap attached to the neck, which allows gas sampling and closes the sampler perfectly after filling. The gas sampler is equipped with a universal valve cap with a long service life. Bottles are used to make it, which previously served as packaging for chemicals and are problematic waste after being emptied. The sampler can be used in chemical laboratories, research institutes, universities, hospitals, plant operations and coal mining. Wherever gas samples are taken and transported for analysis.

Description

247030

The invention is a bast sampler of a gaseous sample container in which it is solved by closing the valve closure.

So far, the most commonly used for gas sampling are glass samplers in the form of cylinders, which are fitted with taps on both ends. The contents of the sampler are also such as to remove any sample from the sample. Pressurized metal samplers provided with a needle valve are used to sample the liquefied hydrocarbon gases. Sealing liquids are used to collect gaseous samples into samples, dispense samples from samplers into analyzers, and move in analyzers. The sealing liquid can be any liquid substance that does not chemically react with the gas with which it is in contact and in which the gas does not dissolve or dissolves only very little. Particularly suitable are water, saline and mercury. Generally, saturated solutions of inorganic salts are used, acidified with a small amount of non-volatile acid such as sulfuric acid and decolorized with methyl orange and methyl red.

In the conventional use of cylinder-shaped glass patterns with taps at the ends, the lubricating grease is filled from the coils, which is reflected not only by the leakage of the sealing liquid but also by the gaseous sample. The cylindrical shape of the sample tube passing through the glass tube with the taps at the top and bottom makes it difficult handling in analytical laboratories and transport in chemical plants. Almost exclusive requires a horizontal position. The lifetime of the glass samplers is therefore small. The repaired and damaged package is very difficult and, in fact, does not react to glass workshops. This leads to considerable loss of materials and energy.

The above mentioned drawbacks are substantially eliminated by the gas sampling bottle of the necked threaded bottle according to the invention, in that the bottle is provided with a valve cap with an internal thread for screwing on the bottle, t with a ring, two threaded spindles for closing and opening the inlet opening, which are provided with flaps from the outside of the valve closure, and a riser tube extending from the inside to the bottom of the bottle on one of the openings.

The present invention has made progress in that a gas sample box consists of a versatile valve cap with a long lifetime and a bottle that can be made of glass, metal, or plastic. A significant benefit of the invention is that it allows the use of flasks that have previously served as packaging for the transport of chemicals and, once emptied, become problematic waste. They are available! sufficient amount in any chemical laboratory. The gas samples according to the invention are practical, have an aesthetic appearance. The handling and transport is convenient and is carried out in bottle bottles. Another advantage is the use of bottles of dark colored glass, especially for gaseous samples which are light-sensitive. The leakage of the sealing fluid from the gas sampler is completely eliminated.

The drawing shows a schematic representation of a gas sampling box in axonometric direction. According to the invention, the bottle 5 with a thread 8 is made of glass, metal material or plastic. A valve closure 2 is threaded onto the neck of the valve, which is provided with an internal thread 8, with an inlet tube 4 and a gasket 3. The valve body of the valve 2 and the threaded spindle 1 are made of a metal material such as aluminum, silicon, teflon, polypropylene or other inert material with respect to the sampled gas . The test ring 3 is made of PVC or silicone rubber. The rising tube 4 is made of Teflon. The inlet cap 2 is the inlet opening 7 and the outlet opening 6. The inlet opening 7 and the outlet opening 6 are provided with threaded spindles 1 and provided with stoppers on the outside of the valve closure.

The sampler must be pired by sampling a gas sample filled with capping fluid 10 up to the neck. The supply pipe of the sampler must be perfectly flushed with the sampled gas. At sampling, the vial is rotated to a position such that the closure fluid 10 is closed by the valve closure 2. At the sampling, the closure fluid 10 is discharged from the sample box via the discharge opening B and the space above the closure liquid level 10 is filled with the sampled gas through stool 4. After filling, the sample is sealed.

When sampling gas, which is a vacuum in tanks, reservoirs, gas-tanks, the sampler is in the basic position, t. the valve closure 2 is above the enclosing liquid bottle 10. The sampled gas enters the sampler through the dispensing opening 6 and expels the closure liquid through the inlet opening 7 through the inlet tube 7. The aperture above the closure liquid level 10 is filled with the sampled gas. After filling, the vial closes perfectly.
