Description

本発明は、蒸気や圧縮空気やガス配管系に発生するドレンをフロートの浮上降下によって弁口を開閉して自動的に排出するフロート式ドレントラップに関し、特に流体中の異物の付着によって弁口が詰まることを防止できるものに関する。   The present invention relates to a float type drain trap that automatically discharges drainage generated in steam, compressed air, or a gas piping system by opening and closing the valve port by floating up and down of the float. It relates to things that can prevent clogging.

従来のフロート式ドレントラップは、弁ケーシングで入口と弁室と出口を形成し、弁室の下部に弁座部材を取り付け、弁座部材に弁室側端の小口径の弁口と弁口下流の大口径の排出口から成る排出通路を形成し、弁室内に弁口を開閉するフロートを配置し、外部から進退操作可能な操作棒を排出通路内に配置したもので、操作棒を進退せしめて弁口内壁に付着した異物を掃除するものである。   In the conventional float drain trap, the valve casing forms an inlet, a valve chamber, and an outlet, and a valve seat member is attached to the lower portion of the valve chamber. A discharge passage consisting of a large-diameter discharge port is formed, a float that opens and closes the valve port is placed in the valve chamber, and an operation rod that can be moved forward and backward from the outside is placed in the discharge passage. It cleans foreign matter adhering to the inner wall of the valve opening.

上記従来のフロート式ドレントラップは、操作棒の外径が弁口の内径よりも小さく、すなわち操作棒の外径が排出口の内径よりも遥かに小さなものであるために、排出口の内壁に付着した異物を掃除できない問題点があった。
実公昭４９−３６７４７号公報 In the conventional float drain trap, the outer diameter of the operation rod is smaller than the inner diameter of the valve port, that is, the outer diameter of the operation rod is much smaller than the inner diameter of the discharge port. There was a problem that the adhered foreign matter could not be cleaned.
Japanese Utility Model Publication No. 49-36747

解決しようとする課題は、弁口及び排出口の内壁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 make it possible to clean foreign matter adhering to the inner walls of the valve port and the discharge port.

本発明は、弁ケーシングで入口と弁室と出口を形成し、弁室の下部に弁座部材を取り付け、弁座部材に弁室側端の小口径の弁口と弁口下流の大口径の排出口から成る排出通路を形成し、弁室内に弁口を開閉するフロートを配置し、外部から進退操作可能な操作棒を排出通路内に配置したフロート式ドレントラップにおいて、操作棒の先端側外径を排出口の内径よりも僅かに小径に形成すると共に操作棒の先端側に切割を設けて内側に変形可能に形成し、操作棒の先端側外周が排出口内壁と弁口内壁を摺動することを特徴とする。   In the present invention, an inlet, a valve chamber, and an outlet are formed by a valve casing, a valve seat member is attached to a lower portion of the valve chamber, and a small-diameter valve port at the valve chamber side end and a large-diameter valve downstream of the valve port A float drain trap with a discharge passage that consists of a discharge port, a float that opens and closes the valve port in the valve chamber, and an operation rod that can be moved back and forth from the outside is placed inside the discharge passage. The diameter is made slightly smaller than the inner diameter of the discharge port, and a cut is provided on the tip side of the operating rod so that it can be deformed inside, and the outer periphery on the tip side of the operating rod slides between the inner wall of the discharge port and the inner wall of the valve port It is characterized by doing.

本発明は、操作棒を進退せしめることにより弁口及び排出口の内壁に付着した異物を掃除できるという優れた効果を生じる。   The present invention produces an excellent effect that foreign matter adhering to the inner wall of the valve port and the discharge port can be cleaned by moving the operating rod back and forth.

本発明の温度応動弁は、操作棒の先端側外径を排出口の内径よりも僅かに小径に形成すると共に操作棒の先端側に切割を設けて内側に変形可能に形成し、操作棒の先端側外周が排出口内壁と弁口内壁を摺動するものであるので、操作棒を進退せしめることにより弁口及び排出口の内壁に付着した異物を掃除できる。   The temperature responsive valve of the present invention is formed such that the outer diameter on the distal end side of the operating rod is slightly smaller than the inner diameter of the discharge port, and a slit is provided on the distal end side of the operating rod so that it can be deformed inward. Since the outer periphery on the tip side slides between the inner wall of the discharge port and the inner wall of the valve port, foreign matter adhering to the inner wall of the valve port and the discharge port can be cleaned by moving the operating rod back and forth.

上記の技術的手段の具体例を示す実施例を説明する（図１参照）。本体１に蓋２をボルトで締結して弁ケーシング形成し、内部に弁室４を形成する。弁室４の上部に入口５を開口させる。入口５と同一軸上に出口７を形成する。本体１の下部に弁座取付口１０から弁座部材８をねじ結合し、弁座取付口１０をプラグ１１で塞ぐ。弁座部材８は弁室４側端の小口径の弁口１２と弁口１２下流の大口径の排出口１３から成る排出通路１４と、立上り通路１５を介して出口７に排出通路１４を連通する４つの通孔１６を有する。弁室４内に弁口１２を開閉する中空球形のフロート１７を自由状態で配置する。   An embodiment showing a specific example of the above technical means will be described (see FIG. 1). A lid 2 is fastened to the main body 1 with a bolt to form a valve casing, and a valve chamber 4 is formed inside. An inlet 5 is opened at the top of the valve chamber 4. An outlet 7 is formed on the same axis as the inlet 5. The valve seat member 8 is screwed to the lower portion of the main body 1 from the valve seat mounting port 10, and the valve seat mounting port 10 is closed with a plug 11. The valve seat member 8 communicates the discharge passage 14 to the outlet 7 through the rising passage 15 and the discharge passage 14 composed of the small-diameter valve port 12 at the end of the valve chamber 4 and the large-diameter discharge port 13 downstream of the valve port 12. The four through holes 16 are provided. A hollow spherical float 17 that opens and closes the valve port 12 is disposed in the valve chamber 4 in a free state.

プラグ１１に外部から進退調節可能に操作棒１８をねじ結合する。操作棒１８はプラグ１１を貫通して先端側が排出通路１４内に位置し、後端側が外部に位置する。操作棒１８の先端側は大径に形成してその外径を排出口１３の内径よりも僅かに小径に形成し、大径部の先端と後端にテーパー部１９，２０を形成する。また操作棒１８の先端側には切割２１を設けて内側に変形可能に形成する。操作棒１８は大径部外周が排出口１３内壁を摺動すると共に内側に変形して弁口１２内壁を摺動する。操作棒１８を覆うキャップ２２をプラグ１１にねじ結合する。   The operating rod 18 is screwed to the plug 11 so as to be adjustable from the outside. The operating rod 18 passes through the plug 11 and has a leading end located in the discharge passage 14 and a rear end located outside. The front end side of the operating rod 18 is formed to have a large diameter, and the outer diameter thereof is formed to be slightly smaller than the inner diameter of the discharge port 13, and tapered portions 19 and 20 are formed at the front and rear ends of the large diameter portion. Further, a slit 21 is provided on the distal end side of the operation rod 18 so as to be deformable inward. The operating rod 18 slides on the inner wall of the valve port 12 while the outer periphery of the large diameter portion slides on the inner wall of the discharge port 13 and is deformed inward. A cap 22 covering the operation rod 18 is screwed to the plug 11.

入口５から流入したドレンは弁室４内に溜り、液面に応じてフロート１７が浮上降下して弁座部材８に離着座して弁口１２を開閉する。弁口１２が開口されると弁室４内のドレンが弁口１２、排出口１３、通孔１６、立上り通路１５を通して出口７に排出され、弁口１２が閉口されると弁室４内の気体の漏出が防止される。   Drain that flows in from the inlet 5 accumulates in the valve chamber 4, and the float 17 rises and falls according to the liquid level and is seated on and off the valve seat member 8 to open and close the valve port 12. When the valve port 12 is opened, the drain in the valve chamber 4 is discharged to the outlet 7 through the valve port 12, the discharge port 13, the through hole 16 and the rising passage 15, and when the valve port 12 is closed, Gas leakage is prevented.

弁口１２及び排出口１３の内壁に付着した異物を掃除する場合、キャップ２２を取り外し、操作棒１８をねじ込んで操作棒１８の先端側外周を排出口１３内壁に摺動させる。さらに操作棒１８をねじ込んで操作棒１８の先端側外周を内側に変形させて弁口１２内壁に摺動させる。   When cleaning the foreign matter adhering to the inner walls of the valve port 12 and the discharge port 13, the cap 22 is removed, the operation rod 18 is screwed, and the outer periphery on the distal end side of the operation rod 18 is slid on the inner wall of the discharge port 13. Further, the operating rod 18 is screwed so that the outer periphery on the tip side of the operating rod 18 is deformed inward and is slid on the inner wall of the valve port 12.
