Description
Technical Field
The invention relates to the field of liquefied petroleum sampling devices, in particular to a piston bottle.
Background
The piston bottle is a sampling bottle for sampling and analyzing liquefied petroleum gas, and is mainly used in the fields of sampling liquefied petroleum gas, sampling environmental gas, laboratory analysis of medical treatment and health, and the like.
The structure adopted at home and abroad at present: a stainless steel cylinder, which is divided into two spaces by a piston in the middle, one side is used for containing a sample, and the other side is used for containing helium. Both sides have a needle valve for closing. The sample enters the cylinder through the sample side valve to close the valve, and the other side is filled with high-pressure inert gas to close the valve. At this time, if the valve on the sample side is opened, the sample is compressed and vaporized by the high-pressure inert gas, and the vaporized gas is available for the user. However, the method has certain problems, namely the sealing problem between the piston and the stainless steel cylinder, the o-ring sealing is adopted at present, and the problem is little when the method is used within one hour, but the leakage between the sample and the inert gas occurs along with the increase of time, and the leakage is more and more in the longer time. This results in the entire sampled sample not reflecting the actual condition of the sample. And during the sliding process of the piston, the o-ring is worn and leakage is generated.
Disclosure of Invention
The invention aims to solve the technical problem of providing a piston bottle, and overcomes the defects of leakage, inconvenience in sampling and the like of the traditional sampling piston bottle.
In order to solve the technical problems, the invention adopts the technical scheme that:
a steel cylinder is tightly arranged between a first flange plate and a second flange plate; a corrugated pipe is arranged in the steel cylinder, one end of the corrugated pipe is fixed on a first flange plate through the first corrugated pipe flange plate, the first flange plate is provided with an opening communicated with the corrugated pipe, and the opening is connected to a first valve; and a piston cylinder is arranged in the corrugated pipe, the opening end of the piston cylinder is fixed with the other end of the corrugated pipe through a second corrugated pipe flange, an opening communicated with the piston cylinder is arranged on the second flange, and the opening is connected to a second valve.
Further, a glass tube is arranged along the length direction of the steel cylinder, and a magnet is placed in the glass tube; and a magnetic ring is fixed on the second corrugated pipe flange plate, and the magnet moves synchronously along with the movement of the magnetic ring.
Furthermore, the first flange plate and the second flange plate are fixed through a screw rod between the first flange plate and the second flange plate and screw caps at two ends of the screw rod.
Furthermore, sealing gaskets are arranged between the steel cylinder and the first flange plate and between the steel cylinder and the second flange plate.
Further, the glass tube is an organic glass tube.
Furthermore, two ends of the glass tube are respectively fixed on the first flange plate and the second flange plate.
Compared with the prior art, the invention has the beneficial effects that: the piston bottle is applied to the fields of petrochemical industry and environment, can greatly improve the working efficiency and ensure the accuracy of sampling analysis.

In the figure: 1-a first valve; 2-a first flange; 3-a screw; 4-a screw cap; 5-a sealing gasket; 6-a first bellows flange; 7-a steel cylinder; 8-a bellows; 9-a piston cylinder; 10-a second bellows flange; 11-a second flange; 12-a second valve; 14-a magnetic ring; 15-a glass tube; 16-magnet.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The piston bottle mainly comprises two valves, a plurality of flange plates, a steel cylinder 7 (or a stainless steel cylinder), a corrugated pipe 8, a piston cylinder 9, a sealing gasket 5, a screw rod 3, a screw cap 4 and the like. The piston cylinder 9 is welded inside the corrugated pipe 8 through a second corrugated pipe flange 10, the corrugated pipe 8 is welded on the first flange 2 through a first corrugated pipe flange 6, and the first valve 1 and the sealing gasket 5 are arranged on the first flange 2; the second flange 11 is provided with a second valve 12 and a gasket 5. The first flange 2 and the second flange 11 are connected and pressed tightly through the screw rod 3 and the screw cap 4. The second bellows flange 10 is sleeved with a magnetic ring 14, when the piston cylinder 9 moves under the action of high-pressure gas, the magnetic ring 14 drives the magnet 16 in the glass tube 15 outside the bottle to move, and the moving position of the piston cylinder 9 can be known through the movement of the magnet 16, so that the using condition of a sample can be known.
When the piston cylinder is used for analyzing liquefied petroleum gas, a sample enters the corrugated pipe 8 from the first valve 1, the space between the corrugated pipe 8 and the piston cylinder 9 is filled with the sample, and the sample side valve is closed after the sample is filled. Then 6MPa of inert gas is filled in through the second valve 12, the liquid sample measured by the sample is vaporized, and the vaporized sample is discharged through the first valve 1 for the user to use. The bellows 8 has been introduced to this piston bottle, separates sample and inert gas completely, can not appear the seepage, can bear 6 MPa's high pressure moreover, and traditional sampling bottle need the continuation let in high-pressure gas at the gas side just can be with the liquid vaporization that the sample surveyed.
When being used for the ambient air sampling, be connected first valve 1 with the vacuum pump, carry out evacuation processing in the bellows 8, close first valve 1 after having taken out the vacuum, when needs sampling, open first valve 1, piston cylinder 9 will drive bellows 8 and stretch backward, in 8 cavities of bellows with the ambient gas suction, when second bellows ring flange 10 moved to the end, closed 1 sampling of first valve and ended.
