Japanese Utility Model Publication No. 49-36747

解決しようとする課題は、自動的に操作部材を進退せしめて弁座部材の排出通路内面に付着した異物を掃除できるようにすることである。   The problem to be solved is to automatically move the operating member back and forth so that foreign matter adhering to the inner surface of the discharge passage of the valve seat member can be cleaned.

本発明は、弁ケーシングで入口と弁室と出口を形成し、弁室を出口側に連通する排出通路を有する弁座部材を取り付け、弁室内に弁座部材に離着座して排出通路を開閉する弁部材を配置し、排出通路内に進退操作可能な操作部材を配置したものにおいて、操作部材に温度応動部材と表示部材を連結し、温度応動部材の変形により、所定の高温以上であれば操作部材を後退させて表示部材を弁ケーシングから突出させ、所定の高温よりも低温になるにしたがって操作部材を前進させて表示部材の弁ケーシングからの突出度合いを小さくすると共に操作部材により弁座部材の排出通路の内面に付着した異物を掃除することを特徴とする。   In the present invention, the valve casing forms an inlet, a valve chamber, and an outlet, and a valve seat member having a discharge passage communicating with the valve chamber on the outlet side is attached. If a valve member is arranged and an operation member capable of advancing and retreating is arranged in the discharge passage, a temperature responsive member and a display member are connected to the operation member, and the temperature responsive member is deformed so that the temperature is not less than a predetermined high temperature. The operating member is retracted to cause the display member to protrude from the valve casing, and the operating member is advanced as the temperature becomes lower than a predetermined high temperature to reduce the degree of protrusion of the display member from the valve casing, and the valve member by the operating member. The foreign matter adhering to the inner surface of the discharge passage is cleaned.

本発明は、温度応動部材の変形によりを進退させ、操作部材により弁座部材の排出通路の内面に付着した異物を掃除するものであるので、自動的に弁座部材の排出通路の内面に付着した異物を掃除することができるという優れた効果を生じる。また、温度応動部材の変形により操作部材を進退させ、表示部材の弁ケーシングからの突出度合いを変化させるものであるので、表示部材の突出度合いにより弁座部材の排出通路の内面に付着した異物の付着度合いを確認することができるという優れた効果を生じる。   The present invention advances and retracts due to the deformation of the temperature responsive member and cleans the foreign matter adhering to the inner surface of the discharge passage of the valve seat member by the operation member, so that it automatically adheres to the inner surface of the discharge passage of the valve seat member. The excellent effect that the foreign material which was made can be cleaned is produced. Further, since the operating member is advanced and retracted by the deformation of the temperature responsive member and the degree of protrusion of the display member from the valve casing is changed, the amount of foreign matter adhering to the inner surface of the discharge passage of the valve seat member is changed depending on the degree of protrusion of the display member. An excellent effect that the degree of adhesion can be confirmed is produced.

本発明のフロート式スチームトラップは、操作部材に温度応動部材と表示部材を連結し、温度応動部材の変形により、所定の高温以上であれば操作部材を後退させて表示部材を弁ケーシングから突出させ、所定の高温よりも低温になるにしたがって操作部材を前進させて表示部材の弁ケーシングからの突出度合いを小さくすると共に操作部材により弁座部材の排出通路の内面に付着した異物を掃除するものである。そのため、スチームトラップが正常にドレンを排出していれば、温度応動部材が所定の高温以上に保たれて操作部材を後退させて表示部材を弁ケーシングから突出させている。そして、弁座部材の排出通路内面に異物が付着してドレンの排出量が低下してくると、温度応動部材が所定の高温よりも低温になるにしたがって操作部材を前進させて表示部材の弁ケーシングからの突出度合いを小さくすると共に操作部材により弁座部材の排出通路の内面に付着した異物を掃除する。   The float type steam trap of the present invention connects the temperature responsive member and the display member to the operation member, and causes the display member to protrude from the valve casing by retreating the operation member when the temperature is higher than a predetermined temperature by deformation of the temperature responsive member. The operation member is advanced as the temperature becomes lower than a predetermined high temperature to reduce the degree of protrusion of the display member from the valve casing, and the operation member cleans foreign matter adhering to the inner surface of the discharge passage of the valve seat member. is there. Therefore, if the steam trap normally discharges the drain, the temperature responsive member is maintained at a predetermined high temperature or higher, and the operating member is retracted to project the display member from the valve casing. When foreign matter adheres to the inner surface of the discharge passage of the valve seat member and the amount of drainage decreases, the operation member is advanced as the temperature-responsive member becomes lower than a predetermined high temperature, and the valve of the display member The degree of protrusion from the casing is reduced, and the foreign matter attached to the inner surface of the discharge passage of the valve seat member is cleaned by the operation member.
