Description

【０００１】
【産業上の利用分野】
この発明は、ロータンクの底部に設置されるフロート弁に関するものである。
【０００２】
【従来の技術及びその課題】
従来、ロータンクの底にはフロート弁が設けられており、フロート弁が開かれるとロータンクに溜められていた洗浄水が便器側へ流下されるように構成されており、従来においては、フロート弁の弁座部の内径寸法は一定のものとなっており、便器の種類によっては、フロート弁から便器側へ流下する吐水流量が多すぎて、洗浄飛沫が増大したり、また便器の封水がなくなってしまう等の不具合が生じ、フロート弁を取り付ける便器の種類によりフロート弁からの吐水流量を調節する必要があるが、前述した如く従来ではフロート弁の内径は一定であり、調節するためには新たにフロート弁を製作する必要があり、コストが増大してしまうという問題点があった。
【０００３】
【課題を解決するための手段】
本発明は上記従来の問題点に鑑み案出したものであって、低コストで容易に吐水流量を調節することのできるフロート弁構造を提供せんことを目的とし、その要旨は、ロータンクの底に設けられて球弁が浮上することにより弁座部が開放され、該弁座部内を通りロータンク内の洗浄水が便器側へ流下されるように構成したフロート弁において、前記弁座部内に各種内径の異なる弁座オリフィスを選択して上方より嵌め込み、該弁座オリフィスにより前記弁座部の内径を調節して前記洗浄水の便器側への吐水流量を調節可能に構成したことである。
【０００４】
【実施例】
以下、本発明の実施例を図面に基づいて説明する。
図１は、フロート弁の全体構成図であり、フロート弁１はロータンクの底にパッキン６を介在させて締付ナット７を底側より締め付けて固定されるものであり、フロート弁１の弁座部２上には球弁３が載置され、この球弁３がフロートカップ４に連結されて、鎖５が引き上げられることにより球弁３が浮上して前記弁座部２が開き、ロータンク内に溜められている洗浄水が弁座部２から便器側へ流下されるように構成されている。なお、図中８はオーバーフロー管であり、また図中９はフロートカップ４の上動を制限するストッパーである。
【０００５】
本例では、図２の要部拡大斜視図で示すように、弁座部２の内周面２ａ内に弁座オリフィス１０を嵌め込み可能となっており、弁座部２の内周面２ａから水平方向に３本設けられた支持板２ｄの中心には弁座ガイド２ｃが立設されているが、前記弁座オリフィス１０には、前記３本の支持板２ｄ，２ｄ，２ｄ内に上方より嵌め込み可能に下端が開放された嵌合溝１０ｃ，１０ｃ，１０ｃが形成されており、弁座オリフィス１０の外周面１０ａが前記内周面２ａに当接状に嵌め込まれるものであり、この弁座オリフィス１０の内径面１０ｂは各種内径寸法の異なるものが用意されており、フロート弁１を取り付ける便器の種類に応じて、この弁座オリフィス１０は各種内径の異なるものから選択して前記内周面２ａに嵌め込み固定することができるものとなっており、内径面１０ｂの内径寸法の短いものを選択すれば便器側へ流下される吐水流量が少なくなり、逆に内径面１０ｂの内径寸法の長いものを選択すれば便器側への吐水流量が大となるものであり、便器の種類によって適宜内径寸法の異なる弁座オリフィス１０を選択することができ、各種内径寸法の異なる弁座オリフィス１０の外周面１０ａの外径寸法は同一であるため、既存のフロート弁の弁座部２の内周面２ａに後発的に嵌め込むことができ、さらに、超音波溶着等の方法により弁座オリフィス１０の外周面１０ａとフロート弁の内周面２ａを溶着させることにより密着状に内周面２ａの内側に弁座オリフィス１０を固定させることができるものとなる。
【０００６】
このように、内径の異なる弁座オリフィス１０を適宜選択して取り付けて便器側へ流下される吐水流量の調節が可能となり、弁座オリフィス１０は簡単な構造であり、樹脂などで低コストで製作することができ、フロート弁１全体を新たなものに製作し直す必要がなく、低コストで便器の種類に応じた吐水流量調節が可能である。
【０００７】
なお、例えば高さの高い密結ロータンクでは水圧が大となり、吐水流量が大となるため、ロータンクの種類によっても、前記弁座オリフィス１０を適宜選択して吐水流量調節を低コストで行うことができるものである。
【０００８】
【発明の効果】
本発明は、ロータンクの底に設けられて球弁が浮上することにより弁座部が開放され、該弁座部内を通りロータンク内の洗浄水が便器側へ流下されるように構成したフロート弁において、前記弁座部内に各種内径の異なる弁座オリフィスを選択して上方より嵌め込み、該弁座オリフィスにより前記弁座部の内径を調節して前記洗浄水の便器側への吐水流量を調節可能に構成したことにより、各種内径の異なる弁座オリフィスを適宜選択してフロート弁の弁座部内に上方より嵌め込み固定させることにより、便器の種類またはロータンクの種類に応じた吐水流量調節が可能となり、弁座オリフィスにより低コストで吐水流量調節が可能となる効果を有する。

[Industrial application fields]
The present invention relates to a float valve installed at the bottom of a low tank.
[0002]
[Prior art and problems]
Conventionally, a float valve is provided at the bottom of the low tank, and when the float valve is opened, the wash water stored in the low tank flows down to the toilet bowl. The inner diameter of the valve seat is constant, and depending on the type of toilet, the amount of water discharged from the float valve to the toilet is too large, resulting in increased washing splashes and no toilet sealing. It is necessary to adjust the flow rate of water discharged from the float valve depending on the type of toilet to which the float valve is attached. However, it is necessary to manufacture a float valve, which increases the cost.
[0003]
[Means for Solving the Problems]
The present invention has been devised in view of the above-mentioned conventional problems, and aims to provide a float valve structure capable of easily adjusting the water discharge flow rate at a low cost. The float valve is provided so that the valve seat is opened when the ball valve rises, and the wash water in the low tank flows down to the toilet bowl through the valve seat. These valve seat orifices are selected and fitted from above , and the inner diameter of the valve seat portion is adjusted by the valve seat orifice so that the flow rate of water discharged to the toilet bowl can be adjusted.
[0004]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an overall configuration diagram of a float valve. The float valve 1 is fixed by tightening a tightening nut 7 from the bottom side with a packing 6 interposed at the bottom of a low tank. A ball valve 3 is placed on the portion 2, and this ball valve 3 is connected to the float cup 4, and when the chain 5 is pulled up, the ball valve 3 is lifted and the valve seat portion 2 is opened. The washing water stored in the tank is configured to flow down from the valve seat portion 2 to the toilet. In the figure, 8 is an overflow pipe, and 9 is a stopper for restricting the upward movement of the float cup 4.
[0005]
In this example, as shown in the enlarged perspective view of the main part of FIG. 2, the valve seat orifice 10 can be fitted into the inner peripheral surface 2 a of the valve seat portion 2, and from the inner peripheral surface 2 a of the valve seat portion 2. A valve seat guide 2c is erected at the center of three support plates 2d provided in the horizontal direction, but the valve seat orifice 10 is located above the three support plates 2d, 2d, 2d from above. Fitting grooves 10c, 10c, 10c having lower ends open so as to be fitted are formed, and the outer peripheral surface 10a of the valve seat orifice 10 is fitted into the inner peripheral surface 2a in contact with the valve seat. The inner diameter surface 10b of the orifice 10 is prepared with various inner diameter dimensions, and the valve seat orifice 10 is selected from those having different inner diameters according to the type of the toilet to which the float valve 1 is attached. Can be fitted and fixed in 2a If the inner diameter surface 10b having a shorter inner diameter size is selected, the discharged water flow is reduced to the toilet side. Conversely, if the inner diameter surface 10b having a longer inner diameter size is selected, the toilet surface side is selected. The valve seat orifice 10 having a different inner diameter can be selected as appropriate depending on the type of toilet, and the outer diameter of the outer peripheral surface 10a of the valve seat orifice 10 having various inner diameters is the same. Therefore, it can be fitted into the inner peripheral surface 2a of the valve seat portion 2 of the existing float valve later, and the inner surface of the float valve and the outer peripheral surface 10a of the valve seat orifice 10 by a method such as ultrasonic welding. By welding the peripheral surface 2a, the valve seat orifice 10 can be fixed inside the inner peripheral surface 2a in close contact.
[0006]
In this way, the valve seat orifices 10 having different inner diameters can be appropriately selected and attached to adjust the flow rate of water discharged to the toilet. The valve seat orifice 10 has a simple structure and can be manufactured at a low cost using resin or the like. Therefore, it is not necessary to make a new float valve 1 as a whole, and it is possible to adjust the water discharge flow rate according to the type of toilet bowl at low cost.
[0007]
Note that, for example, in a high-concentration low tank, the water pressure becomes large and the water discharge flow rate becomes large. Therefore, depending on the type of the low tank, the valve seat orifice 10 can be appropriately selected to adjust the water discharge flow rate at a low cost. It can be done.
[0008]
【The invention's effect】
The present invention relates to a float valve that is provided at the bottom of a low tank so that the valve seat is opened when the ball valve rises, and the wash water in the low tank flows down to the toilet bowl through the valve seat. The valve seat orifices having various inner diameters are selected and fitted from above , and the inner diameter of the valve seat portion is adjusted by the valve seat orifice so that the flow rate of water discharged to the toilet side can be adjusted. By configuring it, valve orifices with different inner diameters are appropriately selected and fitted into the valve seat of the float valve from above, and the discharge water flow rate can be adjusted according to the type of toilet bowl or low tank. The seat orifice has an effect that the discharge water flow rate can be adjusted at low cost.
