Description
【０００１】
【発明の属する分野】
この発明は、スチーム等の流体中に混入している不純物を除去するために流体が流過する流路に配置されるスチームトラップのストレーナに関し、特にストレーナに捕集された不純物を系外に排出することが可能なブロー機能を有するストレーナに関する。
【０００２】
【従来の技術】
従来、管路を流過するスチーム等の流体中に含まれる不純物を除去し、管路に配置された流体機器の故障の原因を排除するストレーナは公知である。かかるストレーナは、管路を配設された流体機器の一次側に配置され、故障等の原因となる不純物が流体機器に流入するのを防止している。従来は、ストレーナに捕集された不純物をストレーナの外に取り出すためには、フィルターをストレーナから取り外すか、若しくはストレーナを迂回するバイパス回路を設けて、ストレーナの清掃時に流体をストレーナからバイパスして流過させつつ清掃を行うようにしている。前者の場合、フィルターが取り外されているため清掃中に流体機器を作動すると流体中の不純物が除去されないまま流体機器に流れる問題があった。又、後者の場合にも、同様に流体中の不純物の除去が出来ないと共に、バイパス回路の付設を必要とし、回路構成を複雑にすると共に、コストがかかる問題がある。
【０００３】
【発明が解決しようとする課題】
この発明は、ブローによるストレーナの清掃時においても、フィルターをストレーナ室内に保持させて流体中の不純物を除去できるようにすると共に、バイパス回路の付設を不要とするストレーナを提供せんとするものである。
【０００４】
【課題を解決するための手段】
上記課題を解決するためにこの発明が採った手段は、トラップ本体(10)内にドレン貯室(13)を形成し、該ドレン貯室(13)内にボールフロート(20)を自由な浮遊を許容して配置し、該ボールフロート(20)の下降時にドレン排出弁(22)が閉弁されるボールフロート式スチームトラップにおいて、一次側配管が接続される一次側連結口(11)とドレン貯室(13)の入口(15)との間に、一次側連結口(11)に直交して垂直に下方に延びるストレーナ室(16)を形成し、該ストレーナ室(16)の内壁に貫通孔(25)を有する保持プラグ(18)を螺着してフィルター (17) を保持し、ストレーナ室(16)の途中にトラップのドレン貯室(13)の入口(15)を開口させ、ストレーナ室(16)の下端は保持プラグ (18) の貫通孔 (25) を通して外部に開放自在であると共に、該貫通孔 (25) を密封し得る密栓プラグ (19) をストレーナ室 (16) の下端の内壁に螺着し、該密栓プラグ (19) の取り外し時に、フィルター (17) が保持プラグ (18) によってストレーナ室 (16) から脱落しないように保持したことを特徴とする。
【０００５】
【発明の実施の形態】
この発明の好ましい実施の形態を、以下に詳細に説明する。この発明は、ストレーナ室内に配置され流体中に含まれる不純物を濾別し得るフィルターを、密栓プラグとは別体のフィルター保持プラグで保持し、該フィルター保持プラグに貫通孔を形成して、ブロー時にフィルターを保持プラグで保持しつつ貫通孔を介してブロー流体を系外に排出可能としたことを特徴とする。
【０００６】
【実施例】
図１は、この発明のストレーナをスチームトラップのストレーナ室に設けたものである。図１を参照して、(10)はトラップ本体であり、一次側連結口(11)に一次側配管が接続され、二次側連結口(12)に二次側配管が接続される。トラップ本体(10)内にはドレン貯室(13)が形成されており、開放された上部はキャップ(14)で閉止される。一次側配管が接続される一次側連結口(11)とドレン貯室(13)の入口(15)との間に、一次側連結口(11)に直交して垂直に下方に延びるストレーナ室(16)が形成される。ストレーナ室(16)内には流体中に混入している不純物を濾別するフィルター(17)が収納、配置される。該フィルター(17)は、貫通孔(25)を穿孔した保持プラグ(18)でストレーナ室(16)から脱落しないように保持されている。ストレーナ室(16)には前記ドレン貯室(13)の入口(15)が開口しており、ストレーナ室の下端は外部に開放されていると共に密栓プラグ(19)で密封される。
【０００７】
ドレン貯室(13)内には、ステンレススティール製の球体からなるボールフロート(20)がレバー等に連結されることなく自由な運動状態で収納され、ドレン貯室(13)内に貯留してくるドレン水によって浮上する。ドレン貯室(13)内にドレン水が貯留されていない状態では、ボールフロート(20)は下降してドレン貯室(13)内の下部突起(21)に着座し、ドレン排出弁(22)に当接して閉弁している。(23)は、ボールフロート(20)を保護するための保護シェルであって、下部を開放し上部を閉塞しただるま状の筒形状を有し、下部大径部と上部小径部及び両部を連続する円弧状部とからなる。ボールフロート(20)は、下部大径部内に収納されており、その内部でドレン水の量に応じて上下に浮動する。下部大径部は、図に示されるようにボールフロート(20)とドレン排出弁(22)との当接を達成するために、後方部を切除した形状に形成されており、円弧状部には複数の孔(24)が穿孔されており、入口(15)から流入してきた流体が保護シェル(23)内に自由に移動するのを許容している。
【０００８】
フィルター(17)の清掃を行う場合には、密栓プラグ(19)を外してストレーナ室(16)を外部に開放する。一次側からスチームを流過させるとスチームはフィルター(17)に捕集されている不純物を押し流しつつ保持プラグ(18)の貫通孔(25)から外部に流出して、フィルター(17)の清掃を行うことができる。清掃後は、密栓プラグを装着してストレーナ室を密封する。
【０００９】
【発明の効果】
この発明によれば、フィルターを保持プラグで保持し、ブロー時にフィルターが外部に流出しないように保持してあるので、ストレーナをブローして捕集された不純物を除去することが出来ると共に、フィルターが保持プラグで保持されているため、ブロー時に流体に混入している不純物はフィルターで捕集され、流体機器に不純物が流入するおそれはない。又、別途のバイパス回路を設ける必要がないため、回路構成が簡単でコストの低下を図ることが出来る。

With reference to FIG. 1 , (10) is a trap main body, and a primary side piping is connected to a primary side connection port (11), and a secondary side piping is connected to a secondary side connection port (12). A drain storage chamber (13) is formed in the trap body (10), and the opened upper portion is closed by a cap (14). Between the primary side connection port (11) to which the primary side pipe is connected and the inlet (15) of the drain storage chamber (13), a strainer chamber (vertically extending downward perpendicular to the primary side connection port (11)) ( 16) is formed. In the strainer chamber (16), a filter (17) for filtering out impurities mixed in the fluid is housed and arranged. The filter (17) is held by a holding plug (18) having a through hole (25) so as not to drop out of the strainer chamber (16). An inlet (15) of the drain storage chamber (13) is opened in the strainer chamber (16), and the lower end of the strainer chamber is opened to the outside and sealed with a sealing plug (19).
[000 7 ]
In the drain storage chamber (13), a ball float (20) made of a stainless steel sphere is stored in a freely moving state without being connected to a lever or the like, and is stored in the drain storage chamber (13). Surfaced by the coming drain water. In a state where drain water is not stored in the drain storage chamber (13), the ball float (20) descends and sits on the lower protrusion (21) in the drain storage chamber (13), and the drain discharge valve (22) The valve is in contact with the valve. (23) is a protective shell for protecting the ball float (20), which has a saddle-like cylindrical shape with the lower part opened and the upper part closed, and the lower large diameter part, the upper small diameter part and both parts It consists of a continuous arc-shaped part. The ball float (20) is housed in the lower large-diameter portion, and floats up and down in accordance with the amount of drain water therein. The lower large-diameter portion is formed in a shape in which the rear portion is cut out in order to achieve contact between the ball float (20) and the drain discharge valve (22) as shown in the figure. A plurality of holes (24) are perforated to allow fluid flowing from the inlet (15) to freely move into the protective shell (23).
[000 8 ]
When cleaning the filter (17), remove the dense plug plug (19) to open the strainer chamber (16) to the outside. When the steam is allowed to flow from the primary side, the steam flows out from the through hole (25) of the holding plug (18) while pushing away the impurities collected in the filter (17), thereby cleaning the filter (17). It can be carried out. After cleaning, a strainer plug is attached to seal the strainer chamber.
[000 9 ]
【The invention's effect】
According to the present invention, the filter is held by the holding plug, and the filter is held so that it does not flow to the outside at the time of blowing. Therefore, the trapped impurities can be removed by blowing the strainer, and the filter Since it is held by the holding plug, impurities mixed in the fluid at the time of blowing are collected by the filter, and there is no possibility that the impurities flow into the fluid device. Further, since it is not necessary to provide a separate bypass circuit, the circuit configuration is simple and the cost can be reduced.
