この発明は、湿式ガスホルダ（多層）の封部の水を常に
一定ノベルに保持しガス漏れ事故の防止を目的とする水
位保持装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water level holding device that maintains water in a sealed portion of a wet gas holder (multilayer) at a constant level at all times to prevent gas leakage accidents.
湿式ガスホルダは周知のごとく、ガスの容器となる鋼板

出して大事故につながるからである。As is well known, a wet gas holder is a cylindrical gas tank made of steel plate that is placed upside down in a water tank, and is constructed so that it can move up and down freely depending on the amount of gas stored in the tank. When the gas tank has multiple layers, the joint between the layers is isolated from the outside air by a seal (cup) and a dip plate. In the case of this wet gas holder, the joint between the upper layer and the lower layer is sealed with water, but the water level at the sealing portion must always be maintained at a level that prevents gas leakage. This is because if the seal water evaporates or leaks from the seal and the water level drops below a certain level, the gas inside will blow out, leading to a major accident.

ましくない。Therefore, the wet gas holder is provided with a water replenishment device for the sealing part as an accessory equipment, so that water is replenished according to the water level of the sealing part. However, because the water level in the seal cannot be easily checked from the outside due to its structure, it is extremely difficult to confirm whether the water in the seal is maintained at a safe water level or whether it is at a dangerous water level. . Therefore, conventional methods have been used, for example, to check the water level in the seal using a float type level meter, or to maintain the water level by continuously supplying water. However, float type level meters are prone to mechanical failure and have low reliability.
Continuous water supply has disadvantages in that it requires a large amount of economic loss in terms of power consumption and leads to corrosion of the holder, but on the other hand, there is a method using an electrode type detector using a low-resistance electrode as a means for detecting the water level. In this method, as shown in Figure 5, two parts of different lengths are placed inside the sealing part (3).
A wooden low-resistance electrode (i) <1> is inserted, and the circuit is configured to turn on and off as the water level rises and falls. However, although this method is highly reliable as a means of detecting water level and has the advantage of being able to properly manage the water level at all times, contact sparks occur between both electrodes <i)<s'> at the time of 0N-OFF. , which is undesirable due to the risk of gas explosion.
この発明は、上記電極式検出器の火花発生の問題を解決
することを目的としてなされたものであり、その要旨は
、水位の変動により電流値が変化するごとく先端が電気
的に接続された２本の高抵抗電極を用い、これに低電圧
を供給することにより流れる電流値により封部の水位を
検出し、その水位に応じて水補給用ポンプが作動、停止
するごとく構成した点にある。This invention was made with the aim of solving the problem of spark generation in the electrode type detector, and its gist is that the tip of the electrode type detector is electrically connected so that the current value changes with fluctuations in the water level. The main feature is that the water level in the sealing part is detected by the value of the current flowing by using a high-resistance electrode and a low voltage is supplied to it, and the water replenishment pump is activated and stopped according to the detected water level.
上記の技術手段によれば、水位検出器に水位の変動によ
り電流値が変化する高抵抗電極を用いたことにより火花
の発生がなく、極めて安全性に富む。また、水位低下の
場合だけでなく、水位オーバーの場合も自動的に給水を
停止させることができるので電力等経済的ロスもない。According to the above-mentioned technical means, since the water level detector uses a high-resistance electrode whose current value changes according to fluctuations in the water level, there is no generation of sparks and the system is extremely safe. In addition, the water supply can be automatically stopped not only when the water level is low but also when the water level is over, so there is no economic loss such as electricity.
さらに、応答性が良好であるので、急激な水位の変動に
も十分対応できる。Furthermore, since the responsiveness is good, it can sufficiently cope with sudden changes in water level.
以下、この発明の一実施例を図面に基づいて説明する。Hereinafter, one embodiment of the present invention will be described based on the drawings.

。As shown in Fig. 1, this invention has a multilayer gas tank (2-1
) (2-2) (2-8) stands upside down in the water tank (1), and the joint between the upper and lower layers is isolated from the outside air by the sealing part (3) and the flood plate (4). As shown in Fig. 2, when the moisture is in the sholder, the tip of each seal (3) is electrically connected so that the current value changes with fluctuations in the water level.
A power supply circuit (5) into which a water level detector (5) consisting of a high-resistance electrode (5-1) is inserted and which supplies a constant voltage to this water level detector (
6). This power supply circuit includes: - a water level stabilizer (for detecting the current value flowing through the high resistance electrode (5-1) of the water level detector (5) and maintaining the water level in the sealing part (3) at a predetermined level; 7) is connected, and an automatic sequence circuit (8) is configured and connected so that the water supply pump (9) automatically operates and stops depending on the water level of the sealing part. Since the sequence circuit described above is well known, the circuit configuration will be omitted.

水位を自動的かつ連続的に検出することができる。Figure 3 shows the correlation between the current flowing through the water level detector (5) and the water level. When a constant voltage is applied to the high resistance electrode (5-1), the water level inside the seal (3) increases. The current i flowing through the high resistance electrode (5-1) changes as shown in the curve in the figure depending on the height. That is, as the water level decreases, the resistance increases, so less current flows through the high resistance electrode (5-1), and conversely, as the water level increases, the resistance decreases, so the current flowing through the high resistance electrode (5-1) decreases.
1) The amount of current flowing through 1) increases. Therefore, the high resistance electrode (5
By detecting the current flowing through -1), the water level in the sealing part (3) can be automatically and continuously detected.

When a voltage of 4V is applied, the current values at the level a at the tip of the high resistance electrode (5-1), the intermediate point b, and the upper end d of the water surface C1 and the flood plate (4) are 24 mA and 48 mA, respectively.
, 80mA, and 240mA. Therefore, for example, when the water level of the sealing part (3) is below point b, the water replenishment pump (9)
If the water level regulator (7) is set so that the pump is activated and the pump is stopped when the water level is above 0, the water level in the seal (3) will always be maintained between the 5 and 0 points. be able to.

6), apply a constant voltage to the water level detector (5),
By simply setting the water level at which the water supply pump (9) operates using the water level setting device (7), the water level in the sealing portion (3) can always be maintained at a safe water level. Furthermore, since a high-resistance electrode with an electrically closed tip is used, there is no generation of sparks (an extremely safe effect).
従って、この発明は可燃ガスホルダにも十分適用可能で
