The conventional gas-in-oil measuring device was developed in U.S. Pat. No. 54-160094.
or Mitsubishi Electric Technical Report VOL.27, No.12-1963. FIG. 1 is a longitudinal cross-sectional view showing the conventional Trithierly type gas-in-oil measuring device shown in the above-mentioned Mitsubishi Electric Technical Report VOL. 27, page 103. In Figure 1, 1 is a gas discharge port, 2 is a two-way tank, 3 is a barrel for collecting dissolved gas in oil and measuring the amount of gas, 4 is a three-way socket, 5 is an oil extraction port, and 6 is a gas extraction port. A container, 7 is a two-way pot for adjusting the amount of mercury (Hg) in the gas extraction container 6, 8 is a mercury reservoir,
9 is a flexible tube for communicating the gas extraction container 6 and the mercury reservoir 8. A procedure for measuring the amount of gas in oil using a conventional gas amount measuring device composed of the above-mentioned parts will be described. First, the flow path of the three-way pot 4 is switched so that the brewet 3 side and the gas extraction container 6 side communicate with each other, and then the pot 2 is opened. Lift the mercury reservoir 8 above the height of the tank 2, open the tank 7, raise the mercury level in the gas extraction container 6 to the tank 2, drain the oil or air in the gas extraction container 6, and then open the tank 7.
Close. Thereafter, the mercury reservoir 8 is lowered, the mercury surface on the gas extraction container 6 side is lowered to just below the three-way pot 4, and the pot 7 is closed. After switching the flow path of the three-way pot 4 so that the oil sampling port 5 side and the gas extraction container 6 side communicate with each other, a container filled with sample oil or the like is connected to the oil sampling port 5. The mercury reservoir 8 is lowered, the pot 7 is opened, and the sample oil is introduced into the gas extraction container 6.
At this time, the sample oil and air bubbles in excess of a predetermined amount are discharged from the oil sampling port 5, the pot 7 is closed, and one of the two ends of the flow path of the three-way pot 4 is connected between the oil sampling port 5 and the gas extraction container 6. During this time, the three-way socket is switched so that the other one is located between the brewet 3 and the gas extraction vessel 6, ie in the neutral position. Mercury reservoir 8
, open the pot 7, lower the mercury level in the gas extraction container 6, and close the pot 7. At this time, the space above the oil surface of the gas extraction container 6 becomes a vacuum. When the gas extraction container 6 is held in hand and shaken vigorously, the sample oil is stirred by the mercury, and the gas dissolved in the oil is released into the space above the oil surface. After shaking, open the pot 7 and lift the mercury surface inside the gas extraction container 6. At this time, dissolved gas accumulates on the oil surface, which is guided to the barrel 3 by switching the three-way tank 4. Repeat the above operation several times to accumulate the dissolved gas in the oil in the oil reservoir 3. Finally, after draining the oil, align the mercury surfaces of the gas extraction container 6 side and the mercury reservoir 8 side, and collect the dissolved gas in the oil. The amount of dissolved gas is read on the scale of the barrel 3. To explain this in more detail, when measuring the extracted gas as described above, the dissolved gas is collected in the burette 3, and this gas is brought to atmospheric pressure and measured on the scale of the burette 3. According to this method,
Gases with high solubility have the problem of being redissolved in the oil remaining in the container when the pressure is returned to atmospheric pressure. Therefore, it is necessary to read the gas amount when there is as little oil as possible. For this reason, after the above-mentioned gas extraction is completed, the sample in the container 6 is discharged from the oil extraction port 5 through the tank 4, and then the tank 4 is switched to raise the mercury in the container 6, which passes through the tank 4 and is discharged from the oil extraction port 5. After the mercury in the mercury reservoir 8 and the mercury in the barrel 3 are aligned, the scale is read.

Although the conventional Trithierly-type gas-in-oil gas meter mentioned above is relatively small, it has health and safety issues, such as using mercury, which is hazardous to hygiene, and the measuring device being made of glass. However, for on-site use, the mercury reservoir and main body are connected by a tube, which poses a problem in that it is very inconvenient to carry. In addition, in order to improve the problems of the above-mentioned conventional methods, a measuring instrument for measuring dissolved gases in oil without using mercury was developed as shown in Japanese Utility Model Application Publication No. 160094/1983. However, the idea disclosed in Japanese Utility Model Application Publication No. 54-160094 uses a vacuum pump to separate dissolved gases in oil, which requires a vacuum pump and a power source to drive it. There were problems in that the size and weight of the device were large, the channel operation was complicated, and the device was not suitable for transportation. This idea was made in order to solve the above-mentioned conventional problems, and the purpose is to provide a simple and convenient to carry gas amount measuring instrument in liquid that does not use mercury. .

Hereinafter, an embodiment of this invention will be described based on the drawings. FIG. 2 is a longitudinal sectional view showing an embodiment of this invention. In Fig. 2, 1 is a discharge port for oil as a sample liquid, 2 is a two-way socket, and 3 is a glass tube that is a transparent tube with a scale for reading the amount of gas in the oil.This glass tube 3 is U-shaped. It has a curved part 3a,
and constitutes one flow path. Reference numeral 9 designates a cylinder-shaped gas extraction container. The glass tube 3 is fitted into the upper part of the container 9, and an O-ring 11 is pressed against the glass tube 3 by a cap nut 10 screwed onto the upper part of the gas extraction container 9. As a result, the glass tube 3 is fixed, and the space between the gas extraction container 9 and the glass tube 3 is sealed. Further, 12 is a piston that slides within the gas extraction container 9, and this piston 12 extends below the gas extraction container 9 and has a grip 12a at its lower end. 13 is an O-ring for sealing between the piston 12 and the gas extraction container 9, 14 is a cap nut screwed onto the gas extraction container 9, and 15 is a piston guide provided on the cap nut 14. , 16 is the other flow path formed in the piston 12 and opens into the gas extraction container 9, 17 is an oil sampling port provided at the tip of this flow path 16 for collecting oil, which is a sample liquid, and 18 is provided in the flow path 16. It's a two-way street. Reference numeral 19 denotes a stopper mechanism for determining the position of the piston 12, and is provided with a pawl 19a that engages with the sawtooth-like unevenness 12b of the piston 12. A procedure for measuring the amount of gas in oil using the gas in oil amount measuring device configured as described above will be described. First, the axis of the measuring instrument is held in the vertical direction, the locks 2 and 18 are opened, the piston 12 is pushed into a predetermined position in the gas extraction container 9, and the piston 12 is fixed by the stopper mechanism 19.
The sample oil is introduced from the sampling port 17 into the gas-in-oil extraction container 9, and then passed through the graduated glass tube 3 to the discharge port 1.
After confirming that there are no air bubbles in the glass tube 3, the pots 2 and 18 are closed. Next, the piston 12 is pulled down. At this time, the pressure inside the gas extraction container 9 becomes reduced. Hold the measuring device in your hand and shake it vigorously to release the gas in the oil onto the oil surface, then tilt the gas extraction container 9 so that the extracted gas enters the graduated glass tube 3, and drain the oil in the graduated glass tube 3. It is dropped into the gas extraction container 9. That is, after shaking the oil, the gas in the oil is extracted to the oil surface and the reduced pressure space. Due to the influence of shaking, oil leaks into the graduated glass tube 3.
Since it is inside, the procedure is to tilt the container and drop it further into the main body. If there is no oil in the graduated glass tube and the oil level and space in the main body are in communication with the graduated glass tube, the extracted gas present in the reduced pressure space will naturally enter the glass tube. Rotate the measuring device with the tip 2 facing up and the axis of the measuring device almost horizontal. When the measuring instrument is rotated, the sample oil enters the graduated glass tube 3, so that the oil level in the extraction container 9 is adjusted to the glass tube 3.
The rotation of the measuring instrument is stopped when it reaches a position higher than the level of the oil inside (the state in which the head pressure of the oil is applied to the inside of the graduated glass tube 3). Then, the space capacity of the graduated glass tube 3 is read. Note that the numerical value engraved on the glass tube 3 is the amount of gas in oil constructed using a Toepler extractor, which is said to have the highest extraction rate. In addition, although the above explanation was about measuring dissolved gas in oil, the device for measuring the amount of gas in liquid of this invention can be used to measure the amount of dissolved gas in other liquids with low vapor pressure. Needless to say.

As explained above, this device consists of a cylinder-shaped gas extraction container whose internal volume is expanded by sliding a manual piston to obtain a reduced pressure or vacuum, and a portion of which is formed by a transparent tube with a scale. a tube communicating with the sample liquid outlet; and a flow path formed within the piston, one end of which opens into the container, and the other end communicating with the sample liquid collection port; Since each of these is equipped with a channel opening/closing means, by not using mercury,
It is excellent in terms of safety and hygiene, and has a simple configuration that allows depressurization or vacuum inside the gas extraction container to be obtained by manually retracting the piston, so it is inexpensive, and it is possible to measure the amount of gas in the liquid under reduced pressure. This has the effect of providing an instrument for measuring the amount of gas in liquid that can be easily used in the field. Furthermore, the inventive gas-in-liquid amount measuring device has the effect of being able to measure with high precision a sample having a relatively small amount of gas in the liquid. To explain this in detail, in the device described in Utility Model Application Publication No. 54-160094 or the Mitsubishi Electric technical report mentioned above, when measuring the extracted gas, the gas is collected into the capillary scale at the top of the cylinder, and the gas is balanced with the atmospheric pressure and then measured. do. According to this method, there is a problem that gases with high solubility re-dissolve in the sample liquid remaining in the container when the gas is returned to atmospheric pressure. In contrast, in this invention, after a part of the extracted gas is sent into a transparent tube with a scale, the extraction container is tilted, and the head pressure of the sample liquid is applied inside the transparent tube with a scale to read the scale. , the inside of the container is not returned to the atmosphere without reading the scale, and therefore the extracted gas is not redissolved. This provides the advantage that highly accurate measurements can be made for samples with a relatively small amount of gas in the liquid.
