Description
本発明は、大気圧又は大気圧以上の正圧蒸気で被加熱物を加熱したり、あるいは、大気圧以下の負圧蒸気で加熱する蒸気加熱装置に関し、特に、加熱装置の出口側で、正圧蒸気の場合には正圧流体圧送手段へと切り換え、一方、負圧蒸気の場合にはエゼクタ式真空ポンプへと切り換えるものに関する。 The present invention relates to a steam heating apparatus that heats an object to be heated with atmospheric pressure or positive pressure steam that is equal to or higher than atmospheric pressure, or that is heated with negative pressure steam that is equal to or lower than atmospheric pressure. In the case of pressurized steam, it relates to what switches to positive pressure fluid pumping means, while in the case of negative pressure steam it switches to an ejector type vacuum pump.
従来の蒸気加熱装置としては、熱交換器の二次側すなわち出口側に切替手段を介在して、エゼクタ式真空ポンプとスチームトラップを設けたもので、複数のバルブで構成する切替手段によって、真空ポンプとスチームトラップとを切り換えて使用するものである。 As a conventional steam heating apparatus, a switching means is interposed on the secondary side of the heat exchanger, that is, an outlet side, and an ejector type vacuum pump and a steam trap are provided. The pump and the steam trap are switched and used.
上記従来の蒸気加熱装置では、切替手段として複数のバルブを用いて切り換える必要があり、加熱装置が複雑化してしまう問題があった。 In the conventional steam heating device, it is necessary to switch using a plurality of valves as switching means, and there is a problem that the heating device becomes complicated.
従って本発明が解決しようとする課題は、切替手段としての複数のバルブを不要にして、構造がシンプルな蒸気加熱装置を得ることである。 Therefore, the problem to be solved by the present invention is to obtain a steam heating apparatus having a simple structure without using a plurality of valves as switching means.
上記の課題を解決するための手段は、熱交換器の入口側へ圧力調整弁を介して加熱用の蒸気供給管を接続し、熱交換器の出口側に切換手段を介してエゼクタ式真空ポンプと大気圧又は大気圧以上の正圧排出管とを接続したものにおいて、切換手段を、圧力応動式の三方切換弁で構成して、当該弁部へ負圧流体が流入してくると負圧流体出口からエゼクタ式真空ポンプへ排出し、一方、弁部へ正圧流体が流入してくると正圧流体出口から正圧流体圧送手段へ排出するものである。 Means for solving the above-mentioned problems are that a steam supply pipe for heating is connected to the inlet side of the heat exchanger via a pressure regulating valve, and an ejector type vacuum pump is connected to the outlet side of the heat exchanger via a switching means. Is connected to a positive pressure discharge pipe at atmospheric pressure or above atmospheric pressure, the switching means is constituted by a pressure-responsive three-way switching valve, and negative pressure fluid flows into the valve section when negative pressure fluid flows into the valve section. The fluid is discharged from the fluid outlet to the ejector type vacuum pump. On the other hand, when the positive pressure fluid flows into the valve portion, the fluid is discharged from the positive pressure fluid outlet to the positive pressure fluid pumping means.
本発明によれば、正圧蒸気と負圧蒸気の切替手段としての複数のバルブを不要にして、構造が簡単な蒸気加熱装置とすることができる。 ADVANTAGE OF THE INVENTION According to this invention, the several valve | bulb as a switching means of positive pressure steam and negative pressure steam is unnecessary, and it can be set as a steam heating apparatus with a simple structure.
本発明は、切換手段を圧力応動式の三方切換弁で構成したことによって、弁部へ負圧流体が流入してくると負圧流体出口からエゼクタ式真空ポンプへ自動的に排出され、一方、弁部へ正圧流体が流入してくると正圧流体出口から正圧流体圧送手段へ自動的に排出される。 In the present invention, since the switching means is constituted by a pressure-responsive three-way switching valve, when negative pressure fluid flows into the valve portion, it is automatically discharged from the negative pressure fluid outlet to the ejector type vacuum pump, When positive pressure fluid flows into the valve portion, it is automatically discharged from the positive pressure fluid outlet to the positive pressure fluid pumping means.
本実施例においては、熱交換器として反応釜２０を用いた例を示す。図１において、反応釜２０と、加熱用蒸気供給管２１と、圧力応動式の三方切換弁としての負圧正圧切換弁２２と、正圧流体管２３、及び、エゼクタ式真空ポンプ２４とで蒸気加熱装置を構成する。

負圧正圧切換弁２２は、圧力応動式の三方切換弁であり、圧力センサ１を連通管２７に取り付けて、その端部を電動アクチュエータ３と連通したもので、弁部へ負圧流体が流入してくると負圧流体出口４からエゼクタ式真空ポンプ２４へ自動的に排出され、一方、弁部へ正圧流体が流入してくると正圧流体出口５から正圧流体圧送手段３６へ自動的に排出される。
The negative pressure / positive pressure switching valve 22 is a pressure-responsive type three-way switching valve, and the pressure sensor 1 is attached to the communication pipe 27 and its end portion communicates with the electric actuator 3, and negative pressure fluid flows into the valve portion. When it flows in, it is automatically discharged from the negative pressure fluid outlet 4 to the ejector
