もに残留するカス量の管理も容易になる。In order to continuously supply container gas, multiple gas containers that match the sound pressure of the gas used may be commonly connected, and in some cases gas may be supplied from all gas containers at the same time. Containers are often changed over and used one after the other. In this way, by switching between containers, there is no need to stop the gas supply even when replacing an empty container with a gas-filled container, and potash can be continuously supplied and the gas remains. It also becomes easier to manage the amount of waste.

A pressure detection switch 13 is connected between the manual main valve l and the pressure reducing valve 7. Similarly,
A pressure reducing valve g and a solenoid valve /q are installed on the manual main valve S of the gas container.

容器の切替装置全体が高価にならざるを得なかった。In such a conventional gas supply method, a pressure detection switch and a solenoid valve are required for each system of multiple gas containers, and an electric circuit for executing a predetermined sequence is required outside of these systems. However, the container switching device as a whole has to become expensive.

別な装置を必要としない容器ガスの供給方法の提供を目
的とする。The present invention has been made in view of the above points, and aims to provide a method for supplying container gas that has a simple configuration of a gas piping system and does not require a special device for switching containers.
以下、添付図面を参照して本発明による容器ガスの供給
方法を説明する。Hereinafter, a method for supplying container gas according to the present invention will be explained with reference to the accompanying drawings.

去する一方、供給カス圧設定用の減圧弁の高圧側に圧力
計、２／を付加したものである。Fig. 2 is a gas piping system diagram for implementing the present invention, in which the same symbols as in Fig. 1 indicate the same elements, and the pressure detection switch and solenoid valve are removed from the piping system in Fig. 1. , a pressure gauge 2/ is added to the high pressure side of the pressure reducing valve for setting the supply gas pressure.
この場合、減圧弁７．ざ、９は設定圧を変更し得るもの
であり、供給ガス圧を設定する減圧弁ＩＯは必ずしも圧
力可変の必要はなく所定の供給ガス圧が得られる圧力固
定型のものであっても良い。In this case, pressure reducing valve 7. First, reference numeral 9 is a device whose set pressure can be changed, and the pressure reducing valve IO for setting the supply gas pressure does not necessarily have to be variable in pressure, and may be of a fixed pressure type that can obtain a predetermined supply gas pressure.

用順に順次低く設定することを特徴とする。In such a piping configuration, the present invention includes a gas container box, 3 manual main valves 'I,! , AK each connected pressure reducing valve? ,
ff, 9 is set to be higher than the set pressure of the pressure reducing valve lθ for setting the supply gas pressure, and the gas container 1. The feature is that the settings are set lower in the order of use of 3 and 3.
すなわち、減圧弁７の設定圧をＰｌ、減圧弁Ｓの設定圧

・・・・・・・・（１）の如く設定する。That is, assuming that the set pressure of the pressure reducing valve 7 is Pl, the set pressure of the pressure reducing valve S is P1, the set pressure of the pressure reducing valve D is P3, and the set pressure of the pressure reducing valve IO is P4, the gas container is set as 7-+co→ When switching in the order of 3, P, >P, >P, ≧P4・

Even if j and A are all opened, is the pressure reducing valve? , f, q outlet (low pressure side) and pressure reducing valve IO inlet (high pressure (1111)
The gas pressure in the piping that commonly connects the two is maintained at Pl. Therefore, the gas in the gas container 3 is not supplied through the pressure reducing valve t9, but only the gas in the gas container is supplied. Thus, when the gas in the gas container l is consumed and the gas pressure in this container drops by approximately P, t, the pressure reducing valve ? , f, q
The gas pressure in the pipe that commonly connects the outlet of the pressure reducing valve lθ and the inlet of the pressure reducing valve lθ is P! This time, only the gas in the gas container 1 is supplied, and the gas in the gas container 3 is not supplied. In the same manner, the gas in the gas container is consumed and the gas pressure in this container is P.
まで降下すると、減圧弁７．ｇ、９の出口と減圧弁ＩＯ
の入口とを共通接続する配管中のガス圧はＰ。When the pressure drops to 7. g, 9 outlet and pressure reducing valve IO
The gas pressure in the piping commonly connected to the inlet of is P.
に降下し、今度はガス容器３内のガスのみが供給され、
ガス容器１１．２内のガスは供給されないとと忙なる。, and this time only the gas in gas container 3 is supplied,
The gas in the gas container 11.2 will be busy if it is not supplied.
このことから明らかなように、ガス容器は順次自動的に
切替えられる。As is clear from this, the gas containers are automatically switched in sequence.

交摸すればよい。In this case, is it the pressure reducing valve? By comparing the set pressure of , t, 9 and the indicated pressure of the pressure gauge, it is possible to determine which container is being supplied with gas, and the indicated pressure of the pressure gauge, 2/, is at P. While descending, you can replace the container with another one.

・・・・・・・・・Reducing pressure 9'17. g, 9
If the angle is set, the gas containers will be switched in the order of 3 → ko → /, and waste container 3 will be used first.

要がかくなる。As is clear from the above questions, the container gas supply method of the present invention eliminates the need for pressure switches, solenoid valves, and electric circuits, compared to conventional gas supply methods, and thereby improves the gas piping system. This greatly simplifies the configuration and eliminates the need to provide a special device for changing containers.
