【０００１】
【産業上の利用分野】
本発明は、１次側流路内を流れる流体の圧力が変動した際においても常に一定なる流量を２次側流路内へ供給する為の定流量電磁弁に関するもので、例えばファンコイルユニットにおける加湿装置等への水の供給あるいは停止に用いられる。
【０００２】
【従来の技術】
従来の定流量電磁弁は、流路内を流れる流体中に含まれる異物を除去する為のストレーナ。流路内を流れる流体圧力を一定圧力に制御する為の減圧弁。流量を一定流量に繰り込む為のオリフィスニップル。流路を開閉して流体の供給、停止を行なう電磁弁、よりなるもので、前記ストレーナ、減圧弁、オリフィスニップル、電磁弁は、格別に用意され、それら各構成がニップル、エルボ等によって配管接続され、システム構成として定流量電磁弁機能を備える。
すなわち、第１配管よりストレーナに流入する流体は、ストレーナにて異物が除去され、清浄なる流体が第２配管を介して減圧弁に供給される。
減圧弁にあっては流入する流体圧力に応じて一定なる流体圧力に制御され、この一定なる圧力に制御された流体は第３配管を介してオリフィスニップルに供給される。
オリフィスニップルにあっては、内部のオリフィスにて一定流量にその流量を制御し、一定流量の流体が第４配管を介して電磁弁に供給される。
一方、電磁弁にあっては、流体の供給時に弁座が開放されて第５配管を介して消費部に向けて流体が供給され、流体の供給停止時において弁座が閉塞され、消費部に向かう流体の供給が停止される。
【０００３】
【発明が解決しようとする課題】
かかる従来の定流量電磁弁システムによると、以下の不具合を有する。
（１）ストレーナ、減圧弁、電磁弁、にあっては、それらの基本部材となる本体部を必ず各構成において必要とするもので、ストレーナ本体、減圧弁本体、電磁弁本体を共用することが困難である。以上によると、各構成部品を製作する上において、部品点数を削減することが困難で部品コスト高、組みつけコスト高、を招来し安価なシステムを供給し得ないものである。
（２）各構成は複数のニップル、エルボ等の連結部材をもって配管接続されるもので、これによると、接続作業に多大な工数を必要とすること、接続部の洩れの確認が必要なこと、から接続作業コストが高価となって好ましいものでない。
又、前記接続によると、特にその接続方向において大型化するものでコンパクトな定流量電磁弁システムを提供できない。
（３）更に、前記各構成のメンテナンスを行なう際、各構成をそれぞれ配管から取り外し、再び取りつける必要があり、これによってメンテナンス性が大きく阻害される。
【０００４】
本発明は、かかる不具合に鑑み成されたもので、単一の本体内に前記各構成を備えることによって構成部品の製造コストの低減、接続作業性の向上、メンテナンス性の向上、更にはコンパクト化、を図ることのできる安価な定流量電磁弁を提供することを目的とする。
【０００５】
【課題を解決する為の手段】
本発明になる定流量電磁弁は、前記目的を達成する為に、弁本体には、その上端から下方に向けて可動コア案内孔が穿設され、
下端から上方に向けて２次側流路が穿設されるとともに２次側流路の上端が弁座をもって可動コア案内孔の底部に開口し、
又、左側端から可動コア案内孔の左側壁に向けて１次側流路が穿設され、
更に、右側端から可動コア案内孔の右側壁に向けて操作杆収納孔が穿設され、
前記可動コア収納孔内には電磁装置を構成する可動コアを移動自在に配置し、１次側流路にストレーナを配置し、２次側流路に絞り部を備え、ゴム材料によって形成されるオリフィス部材を配置し、操作杆収納孔には可動コアの下端に臨むカム部を備えた操作部材を回転自在に配置し、
前記弁座を、弁本体の上端に配置される電磁装置の可動コアの下端に取着せる弁部にて開閉するとともに操作部材の回転によりカム部をもって可動コアを移動し、弁座を機械的に開閉したことを特徴とする。
【０００６】
【作用】
本発明によれば、弁本体に定流量電磁弁の主要構成部位であるストレーナ、電磁弁、定流量弁、の機能を一体的に収納配置できる。
又、電磁装置のコイルへの非通電時にあっても操作部材を回転することによってカム部をして弁座を機械的に開放できる。
【０００７】
【実施例】
以下、本発明になる定流量電磁弁の一実施例について図により説明する。
１は弁本体であり、以下よりなる。
弁本体１の上端１Ａより下方に向けて可動コア案内孔１Ｂが穿設される。
又、弁本体１の左側端１Ｃより可動コア案内孔１Ｂの左側壁に向けて１次側流路１Ｄが穿設され、更に弁本体１の下端１Ｅから上方の可動コア案内孔１Ｂに向けて２次側流路１Ｆが穿設される。このとき、２次側流路１Ｆは、弁座２をもって可動コア案内孔１Ｂに開口する。
【０００８】
以上によると、弁本体１には、１次側流路１Ｄ、可動コア案内孔１Ｂ、弁座２、２次側流路１Ｆ、よりなる流路が形成される。
【０００９】
そして１次側流路１Ｄ内にはストレーナ３が配置される。
このストレーナ３は環状リング３Ａと環状リング３Ａの開口に張設されたネット３Ｂとにより形成されるもので、かかるストレーナ３は１次側流路１Ｄの開口から１次側流路１Ｄ内へ挿入配置される。
以上によると１次側流路１Ｄから可動コア案内孔１Ｂへ向かう流体の異物は、このストレーナ３によって除去され、清浄な流体のみが可動コア案内孔１Ｂ内へと供給される。
【００１０】
弁本体１の上端１Ａには電磁装置Ｓが配置される。
電磁装置Ｓは、環状のコイル４の内方に固定コア５と、固定コア５に対して接離する可動コア６と、可動コア６を固定コア５より離反するよう付勢するプランジャースプリング７と、を備えるもので可動コア６の先端には弁部８を有する。
前記電磁装置Ｓは、前述の如く弁本体１の上端１Ａに配置されるもので、前記可動コア６の下方は、弁本体１の上端１Ａに向かって開口する可動コア収納孔１Ｂに移動自在に配置される。
そして、前記可動コア６の先端に設けた弁部８は、可動コア案内孔１Ｂ内に臨んで開口する弁座２に対応して配置されるもので弁座２は弁部８によって開閉される。
すなわち、コイル４へ通電されると、可動コア６はコイル４によって生起する磁力によって固定コア５側へ吸引されて移動し、これによって弁部８が弁座２を開放し、一方コイル４への通電が断たれると、可動コア６はプランジャースプリング７のバネ力にて固定コア５より離反し、弁部８は、弁座２を再び閉塞保持する。
【００１１】
２次側流路１Ｆにはオリフィス部材９が配置される。
このオリフィス部材９は以下よりなる。
オリフィス部材９は円柱形状をなし、その外径は２次側流路１Ｆに微少な間隙をもって挿入される直径に選定され、その中心部には小径なる絞り部９Ａが貫通して穿設される。
又、オリフィス部材９は弾性を有する例えばゴム材料にて形成されるものであって、絞り部９Ａを流体が通過する際に生ずる負圧力によってその絞り部９Ａの直径が変化する。
すなわち、絞り部９Ａを多量の流体が流下することによると、絞り部９Ａに生起する負圧力は増加し、これによって絞り部９Ａの内径は縮少されて、流体の通過量を自動的に減少させる。
かかるオリフィス部材９は、２次側流路１Ｆの開口から２次側流路１Ｆ内へ挿入され、次いでリング１０をオリフィス部材９に向けて固定配置することによって、２次側流路１Ｆ内に固定される。
【００１２】
以上によると、弁本体１内には、１次側流路１Ｄ、可動コア案内孔１Ｂ、弁座２、２次側流路１Ｆ、よりなる流路が形成され、前記流路の１次側流路１Ｄにストレーナ３が配置され、弁座２に向けて電磁装置Ｓの弁部８が配置され、２次側流路１Ｆにオリフィス部材９が配置される。
【００１３】
又、弁本体１の右側端１Ｇより可動コア案内孔１Ｂの右側壁に向けて操作杆収納孔１Ｈを穿設する。
そして、この操作杆収納孔１Ｈには、操作部材１１が回転自在に配置される。
操作部材１１はその先端にカム部１１Ａを有し、その後端に操作溝１１Ｂを有する。
前記操作部材１１が操作杆収納孔１Ｈ内に挿入配置されると、カム部１１Ａは可動コア案内孔１Ｂ内にあって可動コア６の下端６Ａに臨んで配置される。
そして、操作部材１１の非動作状態にあっては、カム部１１Ａは可動コア６の下端６Ａに当接することがなく間隙Ｐを有する。この状態は図１に示される。
以上によれば、操作部材１１のカム部１１Ａは、可動コア６に対して何等の規制をするものでなく、可動コア６は電磁装置Ｓによって作動される。
【００１４】
次にその作用について説明する。
電磁装置Ｓのコイル４に通電されない状態において、可動コア６はプランジャースプリング７のバネ力によって下方へ押圧され、弁部８は、弁座２を閉塞保持する。以上によると１次側流路１Ｄと２次側流路１Ｆとは遮断されて保持される。
【００１５】
次いで、電磁装置Ｓのコイル４に通電して流体を供給する際について説明する。コイル４に通電されると、可動コア６はコイル４に生起する磁力により、プランジャースプリング７のバネ力に抗して固定コア５側へ移動するもので、可動コア６に装着された弁部８は弁座２を開放する。
以上によると、１次側流路１Ｄ内の流体は、可動コア案内孔１Ｂ、弁座２を介して２次側流路１Ｆ内へと流入する。
【００１６】
そして、１次側流路１Ｄ内を可動コア案内孔１Ｂ内へ向かって流れる流体は、ストレーナ３のネット３Ｂによって異物が除去されるので、弁座２に向かって清浄なる流体を供給できる。従って弁部８による弁座２の閉塞時において確実な閉塞を行なえるとともに弁部８又は弁座２の摩耗を完全に抑止でき、長期に渡って安定した弁閉塞性を保持できる。
【００１７】
一方、弁座２から２次側流路１Ｆ内へ流入する流体の量が所定の量に比較して多くの量が供給されると、オリフィス部材９の絞り部９Ａを通過する流体の流速が増加し、絞り部９Ａに生起する負圧力が大きく増加する。
以上によると、オリフィス部材９が弾性部材にて形成されることから絞り部９Ａは負圧力を受けて内方へ変形し、絞り部９Ａの径を自動的に縮少する。
そして、この絞り部９Ａの径が縮少されたことによると、絞り部９Ａを通過する流体の量を減少でき、もって所定の量に制御された流体を２次側流路１Ｆに向けて供給できたものである。
又、操作部材１１を図１の状態から１８０度回転すると、カム部１１Ａは、可動コア６の下端６Ａに当接するもので、可動コア６は操作部材１１により上動されて弁部８が弁座２を機械的に開放する。
以上によると、弁部８は電磁装置Ｓのコイル４へ通電することなく、弁座２を開放できたもので、例えばコイル４が断線している状態、停電時、あるいは機器の周囲に電源が未だ備えられていない状態、等にあっても定流量弁としての機能を果たすことができる。
【００１８】
【発明の効果】
以上の如く、本発明になる定流量電磁弁によると、弁本体には、その上端から下方に向けて可動コア案内孔が穿設され、
下端から上方に向けて２次側流路が穿設されるとともに２次側流路の上端が弁座をもって可動コア案内孔の底部に開口し、
又、左側端から可動コア案内孔の左側壁に向けて１次側流路が穿設され、
更に、右側端から可動コア案内孔の右側壁に向けて操作杆収納孔が穿設され、
前記可動コア収納孔内には電磁装置を構成する可動コアを移動自在に配置し、１次側流路にストレーナを配置し、２次側流路に絞り部を備え、
ゴム材料によって形成されるオリフィス部材を配置し、操作杆収納孔には可動コアの下端に臨むカム部を備えた操作部材を回転自在に配置し、
前記弁座を、弁本体の上端に配置される電磁装置の可動コアの下端に取着せる弁部にて開閉するとともに操作部材の回転によりカム部をもって可動コアを移動し、弁座を機械的に開閉したので、部品点数を大きく削減できるとともにコンパクトで安価な定流量電磁弁を提供できる。
又、全ての機能が単一の筐体内に配置されることによって接続配管を減少でき、これによると配管の減少、配管接続作業の減少を達成できる。
更にメンテナンス作業を行なう際にあっては、流入路に連なる配管と、吐出路に連なる配管とを取り外すことによって定流量電磁弁を取り出すことができるので、メンテナンス作業性を大きく向上できたものである。
又、操作部材の回転によりカム部をもって可動コアを移動し、弁座を機械的に開閉したことによると、電磁装置へ電流を供給し得ない状態にあっても定流量弁としての機能を果たすことができる。

[00 11 ]
An orifice member 9 is disposed in the secondary flow path 1F.
The orifice member 9 is composed of the following.
The orifice member 9 has a cylindrical shape, and its outer diameter is selected to be a diameter that is inserted into the secondary-side flow path 1F with a minute gap, and a small-diameter restricting portion 9A is drilled through the central portion thereof. .
The orifice member 9 is made of, for example, a rubber material having elasticity, and the diameter of the throttle portion 9A is changed by a negative pressure generated when a fluid passes through the throttle portion 9A.

According to the above, the fluid in the primary channel 1D flows into the secondary channel 1F via the movable core guide hole 1B and the valve seat 2.
[00 16 ]
And since the foreign material is removed by the net | network 3B of the strainer 3 from the fluid which flows into the movable core guide hole 1B in the primary side flow path 1D, the fluid which cleans | cleans toward the valve seat 2 can be supplied.

When the diameter of the throttle portion 9A is reduced, the amount of fluid passing through the throttle portion 9A can be reduced, so that the fluid controlled to a predetermined amount is supplied toward the secondary channel 1F. It was made.
When the operation member 11 is rotated 180 degrees from the state shown in FIG. 1, the cam portion 11A comes into contact with the lower end 6A of the movable core 6, and the movable core 6 is moved up by the operation member 11 so that the valve portion 8 is valved. The seat 2 is mechanically opened.
According to the above, the valve unit 8 can open the valve seat 2 without energizing the coil 4 of the electromagnetic device S. For example, when the coil 4 is disconnected, at the time of a power failure, or when the power is supplied around the device.
