Abstract
Description
本発明は、各種蒸気使用機器や蒸気配管で発生する復水を自動的に排出するスチームトラップに関し、特に、蒸気と復水で加熱冷却されその温度に応じて膨脹収縮する媒体を含む温度制御機素を用いて、所定温度以下の復水を系外へ排出する熱応動式スチームトラップに関する。 The present invention relates to a steam trap that automatically discharges condensate generated in various steam-using devices and steam pipes, and in particular, a temperature controller including a medium that is heated and cooled by steam and condensate and expands and contracts according to the temperature. The present invention relates to a thermally responsive steam trap that discharges condensate at a predetermined temperature or less out of the system using element.
従来の熱応動式スチームトラップは、例えば特許文献１に開示されている。これは、熱応動式スチームトラップの入口側に温度計を取り付けたもので、設定温度の変動に応じて簡単に温度調節することができるものである。 A conventional thermally responsive steam trap is disclosed in Patent Document 1, for example. This is one in which a thermometer is attached to the inlet side of a thermally responsive steam trap, and the temperature can be easily adjusted in accordance with a change in set temperature.
上記従来の熱応動式スチームトラップは、スチームトラップの本体に温度計を取り付けなければならず、スチームトラップの構造が複雑となり、また、トラップのコストも高くなってしまう問題点があった。 The conventional thermoresponsive steam trap has a problem that a thermometer must be attached to the main body of the steam trap, the structure of the steam trap is complicated, and the cost of the trap is increased.
従って、本発明が解決しようとする課題は、トラップ自体の表面温度を測定することのできる構造が簡単で安価な熱応動式スチームトラップを得ることである。 Therefore, the problem to be solved by the present invention is to obtain a heat-responsive steam trap having a simple structure and a low cost that can measure the surface temperature of the trap itself.
本発明は、蒸気と復水で加熱冷却され、その温度に応じて膨脹収縮する媒体を含む温度制御機素を用いて、所定温度以下の復水を系外へ排出するトラップにおいて、トラップの外表面に取り付けるネームプレートの表面に、周囲の温度変化に応じて表示を自動的に変更するサーモラベルを貼り付けたものである。 The present invention relates to a trap for discharging condensate below a predetermined temperature out of the system using a temperature control element including a medium heated and cooled by steam and condensate and expanding and contracting according to the temperature. A thermo label that automatically changes the display according to changes in ambient temperature is pasted on the surface of the name plate attached to the surface.
本発明によれば、ネームプレートの表面にサーモラベルを貼り付けたものであるので、構造が簡単で安価に、トラップ自体の表面温度を測定することができる。 According to the present invention, since the thermo label is attached to the surface of the name plate, the surface temperature of the trap itself can be measured with a simple structure and at a low cost.
以下、本発明の実施の形態について、図１を参照して説明する。図１は、熱応動式スチームトラップの外表面に取り付けるネームプレート１を示しており、このネームプレート１の表面にサーモラベル２を貼り付ける。サーモラベル２は、内蔵した示温部３，４，５が、ネームプレート１の温度に応じて例えば青色から赤色へと順次に変色することによって、ネームプレート１部の温度が、例えば２０℃程度の常温状態であるのか、あるいは１００℃程度の高温状態であるのかを表示するものである。 Hereinafter, an embodiment of the present invention will be described with reference to FIG. FIG. 1 shows a name plate 1 attached to the outer surface of a thermally responsive steam trap, and a thermo label 2 is attached to the surface of the name plate 1. The thermolabel 2 has a built-in temperature indicating portion 3, 4 and 5 that changes color sequentially from blue to red, for example, depending on the temperature of the nameplate 1, so that the temperature of the nameplate 1 portion is about 20 ° C., for example. Whether the temperature is in a normal temperature state or a high temperature state of about 100 ° C. is displayed.
このネームプレート１を取り付けた熱応動式スチームトラップの作動状態を、点検員が点検する場合に、サーモラベル２の示温状態を目視で確認することによって、トラップの外表面が高いのか低いのかをその場で瞬時に判断することができ、点検員がトラップに触れて火傷することを防止することができる。 When the inspector checks the operating state of the thermo-responsive steam trap with the name plate 1 attached, the temperature of the thermo label 2 is visually checked to determine whether the outer surface of the trap is high or low. It is possible to make an instantaneous determination at the site, and it is possible to prevent the inspector from touching the trap and being burned.
本発明は、膨脹媒体を含む温度制御機素を用いて各種蒸気使用機器や蒸気配管で発生する所定温度以下の復水を系外へ排出する熱応動式スチームトラップに利用することができる。 INDUSTRIAL APPLICABILITY The present invention can be used for a thermally responsive steam trap that uses a temperature control element including an expansion medium to discharge condensed water having a predetermined temperature or less generated in various steam-using devices and steam pipes to the outside of the system.
