【従来の技術】[Prior art]

ガス発生を伴なう発酵実験等においては、ガス発生量が発酵過程を把握する一つの主要な指標となっている。従来Ｕ字管を使用したガス発生量測定装置として汎用されているワールブルグ検圧計は図２に示すように反応系に連絡された閉脚ａと、大気に連通する開脚ｂとよりなるＵ字管に検圧計が填装され、同Ｕ字管の液体によってガス発生量を計測していた。 In fermentation experiments involving gas generation, the amount of gas generated is one of the main indicators for understanding the fermentation process. As shown in Fig. 2, the Warburg pressure gauge, which is generally used as a gas generation measuring device using a U-shaped tube, has a U-shaped tube composed of a closed leg a connected to the reaction system and an open leg b communicating with the atmosphere. A pressure gauge was installed in the and the amount of gas generated was measured by the liquid in the U-shaped tube.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら前記従来の測定装置は、総ガス発生量が少量である場合の測定には十分に適用できるが、総ガス量の多い場合には限界があり、広範囲のガス発生量に対応できず、また自動連続測定ができない等の問題点があった。 However, the above-mentioned conventional measuring device can be sufficiently applied to the measurement when the total gas generation amount is small, but there is a limit when the total gas generation amount is large, and it cannot cope with a wide range of gas generation amount. There was a problem that automatic continuous measurement was not possible.

【０００５】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

本考案はこのような問題点を解決するために提案されたもので、液体が填装されたＵ字管と、ガス発生源に接続された管路における同管路より岐出された前記Ｕ字管の一方の垂直支管に連通する管路及び系外に延びる管路の分岐部に介装された三方電磁弁と、同電磁弁作動用電気回路と、同電気回路に介装されたカウンタと、前記Ｕ字管の他方の垂直支管内の液面に浮泛する導電性浮子と、前記他方の垂直支管の上端部において前記電気回路に介装され、前記浮子との離隔、接触に対応して前記電気回路を開閉する導電性電極とより構成したことによって、前記問題点を解決するものである。 The present invention has been proposed in order to solve such a problem, and a U-shaped tube filled with a liquid and a pipe connected to a gas generation source are connected to the pipe. A three-way solenoid valve provided at a branch portion of a pipeline communicating with one vertical branch of the U-shaped pipe and a pipeline extending outside the system, an electrical circuit for operating the solenoid valve, and an electrical circuit for operating the same. A counter, a conductive float floating on the liquid surface in the other vertical branch of the U-shaped pipe, and an electric circuit interposed at the upper end of the other vertical branch of the U-tube, and separated from and in contact with the float. In order to solve the above-mentioned problems, the above-mentioned problems are solved by comprising the conductive electrodes for opening and closing the electric circuit.

【０００６】[0006]

【作用】[Action]

本考案は前記したように構成されているので、常時はガス発生源に接続された管路が開かれ、系外に延びる管路が閉じられ、従って発生ガスは前記電磁弁を経てＵ字管の一方の垂直支管に入り、ガス圧力によってＵ字管の他方の垂直支管内の液体を押上げ、同支管内の液面に浮泛する導電性浮子を上昇させる。 Since the present invention is configured as described above, the pipe line connected to the gas generation source is normally opened and the pipe line extending to the outside of the system is closed, so that the generated gas is U-shaped through the solenoid valve. The liquid enters the other vertical branch pipe of the U-shaped pipe by gas pressure entering one of the vertical branch pipes, and the conductive float floating on the liquid surface in the branch pipe rises.

【０００７】而して一定量の発生ガスがＵ字管内に入り、前記他方の垂直支管内に浮泛する浮子が他方の垂直支管の上端に配設された電極に接触すると、前記三方電磁弁作動用電気回路を閉じて前記三方電磁弁を励磁し、ガス発生源に接続する管路を閉じ、系外に延びる管路を開く。これに伴って前記Ｕ字管における他方の垂直支管の液面が下降し、同液面に浮泛する浮子と前記電極との接触が解除されて前記電気回路が開かれ、電磁弁が消磁されることによって、ガス発生源からのガスが電磁弁を介してＵ字管における一方の垂直支管に進入する。Then, a certain amount of generated gas enters the U-shaped pipe, and when the float floating in the other vertical branch pipe comes into contact with the electrode arranged at the upper end of the other vertical branch pipe, the three-way solenoid valve operation is performed. The electric circuit for operation is closed to excite the three-way solenoid valve, the pipe connecting to the gas generating source is closed, and the pipe extending to the outside of the system is opened. Along with this, the liquid level of the other vertical branch pipe of the U-shaped pipe descends, the contact between the float floating on the liquid level and the electrode is released, the electric circuit is opened, and the solenoid valve is demagnetized. By doing so, the gas from the gas generation source enters one vertical branch pipe of the U-shaped pipe through the solenoid valve.

【０００８】従って前記電磁弁の作動回数を前記電気回路中に介装されたカウンタによって自動計測することによって、発生ガス量を測定することができる。Therefore, the amount of generated gas can be measured by automatically measuring the number of times of operation of the solenoid valve by a counter provided in the electric circuit.

【０００９】[0009]

【実施例】【Example】

以下本発明を図示の実施例について説明する。１はＵ字管で液体２が充填されている。Ｕ字管１における一方の垂直支管１ａの開口部上部には、ガス発生源に接続された管路３における同垂直支管１ａに連通する管路４と、大気に連通する管路５との分岐部において、ガス発生源からのガスを前記垂直支管１ａ及び大気中に切替え供送する三方電磁弁６が配設されている。 The present invention will be described below with reference to the illustrated embodiments. A U-shaped tube 1 is filled with a liquid 2. At the upper part of the opening of one vertical branch pipe 1a in the U-shaped pipe 1, there are provided a pipeline 4 communicating with the vertical branch pipe 1a in the pipeline 3 connected to the gas generation source and a pipeline 5 communicating with the atmosphere. At the branch portion, a three-way solenoid valve 6 for switching and feeding the gas from the gas generation source to the vertical branch pipe 1a and the atmosphere is provided.

【００１０】７は同三方電磁弁６作動用電気回路で、カウンタ８及び前記Ｕ字管１における他方の垂直支管１ｂの上端開口部に臨む電極９が介装されている。図中１０は電源である。更に前記他方の垂直支管１ｂには目盛１１が設けられるとともに、同垂直支管１ｂ内の液面に、誘電率の高い金属箔で被覆した導電性浮子１２が浮泛している。Reference numeral 7 denotes an electric circuit for operating the same three-way solenoid valve 6, which is provided with a counter 8 and an electrode 9 facing the upper end opening of the other vertical branch pipe 1b of the U-shaped pipe 1. In the figure, 10 is a power supply. Further, a scale 11 is provided on the other vertical branch pipe 1b, and a conductive float 12 covered with a metal foil having a high dielectric constant floats on the liquid surface in the vertical branch pipe 1b.

【００１１】而して前記三方電磁弁６は、常時は管路３を「開」、管路５を「閉」の状態としていて、ガス発生とともに同ガスは管路３，４を経てＵ字管１の一方の垂直支管１ａに入り、他方の垂直支管１ｂの液面が上昇する。而してガス発生量が一定量に達するとＵ字管の他方の垂直支管１ｂの液面に浮泛する浮子１２が上昇し、電極９と接触することによって電気回路７が閉じて電磁弁６が励磁され、管路３が「閉」となり管路５が「開」となるので、Ｕ字管１内におけるガス加圧力が解放され、液面が同Ｕ字管１の両垂直支管１ａ，１ｂで同じ高さになろうとし、一方の垂直支管１ａ内のガスは系外に排出される。Thus, the three-way solenoid valve 6 always keeps the conduit 3 “open” and the conduit 5 “closed”, and when the gas is generated, the gas passes through the conduits 3 and 4. The liquid enters the one vertical branch pipe 1a of the U-shaped pipe 1 and the liquid level of the other vertical branch pipe 1b rises. When the amount of gas generation reaches a certain amount, the float 12 floating on the liquid surface of the other vertical branch pipe 1b of the U-shaped pipe rises and comes into contact with the electrode 9 to close the electric circuit 7 and close the electromagnetic valve. 6 is excited, the pipe line 3 is “closed” and the pipe line 5 is “open”, so that the gas pressure in the U-shaped pipe 1 is released, and the liquid level is on both vertical branch pipes 1a of the U-shaped pipe 1. , 1b try to reach the same height, and the gas in one vertical branch pipe 1a is discharged to the outside of the system.

【００１２】同時に電極９と浮子１２とが離隔して電気回路７が開かれ、電磁弁６が消磁されることによって管路３が「開」、管路５が「閉」となり、前記Ｕ字管１における両垂直支管１ａ，１ｂの液面も同じ高さの元の状態に戻る。この電磁弁６の作動回数を電気的にカウンタ８で測定することによって、総発生ガス量が測定される。At the same time, the electrode 9 and the float 12 are separated from each other, the electric circuit 7 is opened, and the solenoid valve 6 is demagnetized to open the pipe line 3 and close the pipe line 5 to form the U-shape. The liquid level of both vertical branch pipes 1a and 1b in the pipe 1 also returns to the original state of the same height. The total amount of generated gas is measured by electrically measuring the number of operations of the solenoid valve 6 with the counter 8.

【００１３】また１単位発生量以下のガス発生量は垂直支管１ｂの目盛１１で読取られる。なお前記管路４と垂直支管１ａとの接続部は真空ずりガラスジョイントとし、また垂直支管１ｂと電極９との接続はプラスチック等よりなる有孔ねじ栓１３による。かくして真空ずり部とねじ栓部のみ共通の各種の大きさのＵ字管が使用でき反応系の総発生ガス量に見合ったＵ字管を使用できる。Further, a gas generation amount of 1 unit or less is read by the scale 11 of the vertical branch pipe 1b. The connection between the pipe 4 and the vertical branch pipe 1a is a vacuum shear glass joint, and the connection between the vertical branch pipe 1b and the electrode 9 is by a perforated screw plug 13 made of plastic or the like. In this way, U-shaped tubes of various sizes that are common only to the vacuum shear section and the screw plug section can be used, and a U-shaped tube corresponding to the total amount of gas generated in the reaction system can be used.

【００１４】またＵ字管１に填装する液体としては、発生ガスの溶解度を小さくするために低ｐＨ、高濃度塩類溶液等を用いてもよい。As the liquid filled in the U-shaped tube 1, a low pH, high concentration salt solution or the like may be used in order to reduce the solubility of the generated gas.

The electric circuit is opened and closed by separating and contacting the electrode interposed in the electric circuit for operation, and the U-tube connected to the gas generation source in the U-tube is connected to the U-tube. Introduce a fixed amount of gas into the U-shaped pipe by demagnetizing or exciting a three-way solenoid valve that is connected to one of the vertical branch pipes and extends outside the system and is connected to the branch of the pipe that communicates with the atmosphere. The amount of generated gas can be automatically and continuously measured by eliminating and measuring the number of times the solenoid valve is operated by a counter provided in the electric circuit.
