Description
本発明は、蒸気配管系で発生する蒸気の凝縮水としての復水を、フロートの浮上降下により自動的に系外へ排出するフロート式スチームトラップに関し、特に、フロートにより開閉される弁孔に付着した異物を洗浄できるものに関する。 The present invention relates to a float type steam trap that automatically discharges condensate as condensate of steam generated in a steam piping system to the outside of the system by floating up and down of the float, and in particular, adheres to a valve hole that is opened and closed by the float. It is related with what can wash the foreign material.
従来のフロート式トラップは、例えば特許文献１に開示されている。これは、ケーシングで入口と弁室と出口を形成し、弁室の下部に弁室を出口側に連通する弁孔を有する弁座部材を設け、弁孔を開閉するフロートを弁室内に配置し、弁孔内に外部から手動で進退操作可能な操作部材を配置して操作部材の進退により弁孔の内面に付着した異物を掃除するものである。 A conventional float trap is disclosed in, for example, Patent Document 1. This is because a casing is formed with an inlet, a valve chamber, and an outlet, a valve seat member having a valve hole that communicates the valve chamber with the outlet side is provided at the lower portion of the valve chamber, and a float that opens and closes the valve hole is disposed in the valve chamber. An operation member that can be manually operated to advance and retract from the outside is disposed in the valve hole, and foreign matter adhering to the inner surface of the valve hole due to advancement and retraction of the operation member is cleaned.
上記従来のフロート式トラップは、手動により操作部材を進退させるものであるために、弁孔の内面に付着した異物を掃除するのに手間隙の掛かる問題点があった。 The conventional float trap has a problem that a manual gap is required to clean the foreign matter adhering to the inner surface of the valve hole because the operating member is manually advanced and retracted.
従って、本発明が解決しようとする課題は、簡単且つ確実に弁孔に付着した異物を取り除くことのできるフロート式スチームトラップを提供することである。 Therefore, the problem to be solved by the present invention is to provide a float type steam trap that can easily and reliably remove foreign substances adhering to a valve hole.
上記の課題を解決するための本発明は、ケーシングで入口と弁室と出口を形成し、弁室の下部に弁室を出口側と連通する弁孔を有する弁座部材を設け、弁孔を開閉するフロートを弁室内に配置したものにおいて、弁座部材を球形に形成すると共に弁孔をＴ字状に形成した球形弁座部材をケーシングに回転操作可能に配置し、球形弁座部材の弁孔に対向するケーシングに球形弁座部材の清掃口を貫通して設けたものである。 In order to solve the above problems, the present invention provides a valve seat member having a valve hole that forms an inlet, a valve chamber, and an outlet in a casing, and communicates the valve chamber with the outlet side at a lower portion of the valve chamber. A valve seat member having a spherical valve seat member formed in a spherical shape and a valve hole formed in a T-shape so as to be rotatable in a casing. A spherical valve seat member cleaning port is provided through a casing facing the hole.
本発明によれば、球形弁座部材をケーシングに回転操作可能に配置し、且つ、球形弁座部材の弁孔に対向するケーシングに球形弁座部材の清掃口を貫通して設けたことにより、清掃口を介して直接に弁孔を清掃することができ、弁孔に付着した異物を簡単且つ確実に取り除くことができる。 According to the present invention, the spherical valve seat member is disposed in the casing so as to be rotatable, and the casing facing the valve hole of the spherical valve seat member is provided through the cleaning port of the spherical valve seat member. The valve hole can be cleaned directly through the cleaning port, and foreign matter adhering to the valve hole can be easily and reliably removed.
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。本体１に蓋２を図示しないボルトで締結して内部に弁室４を有するケーシングを形成する。本体１は入口５と出口７を有する。入口５は弁室４の上部に連通すると共に、入口５と出口７は同一軸上に形成する。弁室４の下部にＴ字状の弁孔１０を開けた球形弁座部材３を配置する。球形弁座部材３は、外部より回転操作可能に取り付ける。Ｔ字状の弁孔１０は、図１に示す状態は外部から弁孔１０を清掃する場合の回転位置であり、通常のスチームトラップとして用いる場合は、図１の状態から９０度だけ反時計方向に回転して用いる。 Hereinafter, an embodiment of the present invention will be described with reference to FIG. A lid 2 is fastened to the main body 1 with a bolt (not shown) to form a casing having a valve chamber 4 therein. The main body 1 has an inlet 5 and an outlet 7. The inlet 5 communicates with the upper portion of the valve chamber 4, and the inlet 5 and the outlet 7 are formed on the same axis. A spherical valve seat member 3 having a T-shaped valve hole 10 is disposed below the valve chamber 4. The spherical valve seat member 3 is attached to be rotatable from the outside. The T-shaped valve hole 10 is a rotational position when the valve hole 10 is cleaned from the outside in the state shown in FIG. 1, and when used as a normal steam trap, it is counterclockwise by 90 degrees from the state shown in FIG. Rotate to use.
弁室４内に球形弁座部材３に離着座して弁孔１０の一端を開閉する中空球形のフロート１３を自由状態で配置する。フロート１３が弁孔１０の一端を閉じた位置で当接するフロート座１４をフロート１３の下方に設ける。 A hollow spherical float 13 that opens and closes one end of the valve hole 10 by being seated on and off the spherical valve seat member 3 in the valve chamber 4 is disposed in a free state. A float seat 14 with which the float 13 abuts at a position where one end of the valve hole 10 is closed is provided below the float 13.
球形弁座部材３のＴ字状弁孔１０の一端に対向する本体１に、外部から直接に弁孔１０を清掃することのできる清掃口１１を貫通して設ける。球形弁座部材３は、本体１に取り付けた弁座保持部材１２で保持する。球形弁座部材３の上方に通路６を設けて出口７と連通する。 The main body 1 facing one end of the T-shaped valve hole 10 of the spherical valve seat member 3 is provided with a cleaning port 11 through which the valve hole 10 can be cleaned directly from the outside. The spherical valve seat member 3 is held by a valve seat holding member 12 attached to the main body 1. A passage 6 is provided above the spherical valve seat member 3 to communicate with the outlet 7.
上記のフロート式スチームトラップの動作は次の通りである。通常は図１の状態から球形弁座部材３を９０度だけ半時計方向へ回転させて使用する。入口５から流入した復水は弁室４内へ流下する。弁室４内に溜まった復水の液面に応じてフロート１３が浮上降下して球形弁座部材３に離着座して弁孔１０の一端を開閉する。弁孔１０の一端が開けられると弁室４内の復水が弁孔１０から通路６を通して出口７に排出され、弁孔１０の一端が閉じられると弁室４内の蒸気の漏出が防止される。 The operation of the float type steam trap is as follows. Normally, the spherical valve seat member 3 is rotated 90 degrees counterclockwise from the state shown in FIG. Condensate flowing in from the inlet 5 flows down into the valve chamber 4. The float 13 rises and falls according to the liquid level of the condensate accumulated in the valve chamber 4 and is seated on and off the spherical valve seat member 3 to open and close one end of the valve hole 10. When one end of the valve hole 10 is opened, condensate in the valve chamber 4 is discharged from the valve hole 10 through the passage 6 to the outlet 7, and when one end of the valve hole 10 is closed, leakage of steam in the valve chamber 4 is prevented. The
弁孔１０にゴミや鉄錆やスケール等の異物が付着した場合は、Ｔ字状の弁孔１０を図１に示す状態とすることによって、清掃口１１から弁孔１０を直接に清掃することができる。 When foreign matter such as dust, iron rust or scale adheres to the valve hole 10, the valve hole 10 is directly cleaned from the cleaning port 11 by setting the T-shaped valve hole 10 to the state shown in FIG. Can do.
本発明は、上記のフリーフロート式スチームトラップに限らずレバーフロート式スチームトラップにも利用することができる。 The present invention can be used not only for the above-mentioned free float type steam trap but also for a lever float type steam trap.
