Description

本発明は、制御弁に関するものである。   The present invention relates to a control valve.

一般的に貯湯式給湯機は、加熱手段により貯湯槽内の低温水を加熱することにより高温水とし、その高温水を同じ貯湯槽内へ貯湯し、低温水と水回路内で混合することにより目標温度に制御して熱利用端末へ供給している。   In general, hot water storage hot water heaters use hot means to heat the low-temperature water in the hot water tank into hot water, store the hot water in the same hot water tank, and mix the low-temperature water with the water circuit. The target temperature is controlled and supplied to the heat utilization terminal.

そして、従来この種の水回路内に搭載されている流路可変機構を有する制御弁１は、湯水混合弁、流量調整弁、切替え弁などとして用いられ、様々な機能を有しているが、基本構造としては、図３に示すように弁本体２と弁体３と弁体蓋４と動力源５とねじ６により構成されている。   And the control valve 1 which has the flow path variable mechanism conventionally mounted in this kind of water circuit is used as a hot-water mixing valve, a flow control valve, a switching valve, etc., and has various functions, As shown in FIG. 3, the basic structure includes a valve body 2, a valve body 3, a valve body lid 4, a power source 5, and a screw 6.

そして、前記弁体３を押さえ込むために前記弁体蓋４で挿入口を塞ぎ、前記弁体蓋４を前記ねじ６で前記弁本体２に締結することで固定し、前記動力源５を前記弁本体２に取り付けることにより前記弁体３を前記動力源５により制御することが可能な構成としている（例えば、特許文献１、特許文献２参照）。   Then, in order to hold down the valve body 3, the valve body cover 4 closes the insertion port, the valve body cover 4 is fastened to the valve body 2 with the screw 6, and the power source 5 is fixed to the valve body. It is set as the structure which can control the said valve body 3 by the said power source 5 by attaching to the main body 2 (for example, refer patent document 1 and patent document 2).

しかしながら、前記従来の構成では、前記弁体３、前記弁体蓋４、前記動力源５が故障した場合、部品交換、あるいは修理のため、ねじ６を外す必要があるが、ねじは一般的に樹脂部品に締結した場合、一度取り外し再締結した場合には締結力が弱くなることが知られているため、ねじを外し、同一弁本体に再度ねじを締結することは、部品の破損、水漏れにつながり、安全性の面からふさわしくない。   However, in the conventional configuration, when the valve body 3, the valve body lid 4, and the power source 5 break down, it is necessary to remove the screw 6 for replacement of parts or repair. Since it is known that the fastening force will be weakened once it is removed and re-fastened when it is fastened to a resin part, removing the screw and re-fastening the screw to the same valve body will cause damage to the part, water leakage It is connected and is not suitable from a safety aspect.

そのため、前記弁体３、前記弁体蓋４、前記動力源５が故障した場合、前記弁本体２ごと部品を交換する必要がある。よって交換部品点数が、故障した部品数よりも多くなるため、サービスパーツのコストが増大する。   Therefore, when the valve body 3, the valve body lid 4, and the power source 5 are out of order, it is necessary to replace parts together with the valve body 2. Therefore, since the number of replacement parts is larger than the number of failed parts, the cost of service parts increases.

本発明は、前記従来の課題を解決するもので、部品交換時における作業性の向上およびコスト低減を実現する制御弁を提供することを目的とする。   The present invention solves the above-described conventional problems, and an object of the present invention is to provide a control valve that realizes improvement in workability and cost reduction during component replacement.

第１の発明は、流路を形成する弁本体と、前記弁本体内で駆動する弁体と、前記弁体を覆う弁体蓋と、前記弁体を駆動させ、前記弁体蓋に固定された動力源とを備え、前記弁体蓋と前記弁本体とを着脱できる構成としたことを特徴とする制御弁である。   The first invention includes a valve body that forms a flow path, a valve body that is driven in the valve body, a valve body cover that covers the valve body, and the valve body that is driven and fixed to the valve body cover. A control valve characterized in that the valve body lid and the valve body can be attached and detached.

これによって、部品交換時には、動力源を組み付けた弁体蓋を、弁本体から取り外すことで、故障部品を交換することができ、その結果、制御弁の弁体、弁体蓋、動力源が故障した際の、交換部品点数増加を防止でき、部品交換時における作業性の向上およびコスト低減を実現できる。   As a result, when replacing parts, it is possible to replace the failed part by removing the valve body cover with the power source assembled from the valve body. As a result, the valve body, valve body cover, and power source of the control valve will fail. In this case, it is possible to prevent an increase in the number of replacement parts, and it is possible to improve workability and reduce costs when replacing parts.

第２の発明は、前記弁体蓋を前記弁本体に装着するために、止め具を用いたことを特徴とするもので、部品交換時には、止め具の着脱のみで容易に、動力源を組み付けた弁体蓋を弁本体から取り外すことができ、部品交換時の作業性を向上できる。   The second invention is characterized in that a stopper is used to attach the valve body lid to the valve body.

これによって、前記弁本体と前記弁体蓋、及び前記弁体蓋と前記動力源の相対位置が一意的に決まり、誤取付け等の組立上の不具合を予防することができる。   Accordingly, the relative positions of the valve body and the valve body lid, and the valve body lid and the power source are uniquely determined, and assembly problems such as erroneous attachment can be prevented.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は、本発明の実施の形態１における給湯機に搭載した制御弁１の構造を示したものである。 (Embodiment 1)
FIG. 1 shows the structure of a control valve 1 mounted on a water heater in Embodiment 1 of the present invention.

制御弁１は、弁本体２と、弁体３と、弁体蓋４と、動力源５と、ねじ６と、止め輪７で構成されており、前記弁体蓋４と前記動力源５は、前記ねじ６を弁体蓋にねじ込むことで固定されている。   The control valve 1 includes a valve body 2, a valve body 3, a valve body lid 4, a power source 5, a screw 6, and a retaining ring 7, and the valve body lid 4 and the power source 5 are The screw 6 is fixed by screwing it into the valve body lid.

また、前記弁体蓋４には、２つの前記ねじ６の取り付け位置の中点に関して非点対称な位置に穴が設けられ、前記動力源５には前記弁体蓋４に設けた穴の位置にピンが設けられているため、組立時には穴にピンがはまることで、正しい相対位置でのみ取付けが可能になっている。   Further, the valve body cover 4 is provided with a hole at an asymmetrical position with respect to the midpoint of the mounting position of the two screws 6, and the power source 5 has a hole position provided in the valve body cover 4. Since the pin is provided in the assembly, the pin can be fitted into the hole at the time of assembly so that it can be mounted only at the correct relative position.

また、前記弁本体２と前記弁体蓋４の嵌め合いの形状を、２つの前記ねじ６の取り付け位置の中点に関して非点対称な形状にすることで、組立時には正しい相対位置でのみ取付けが可能になっている。   Further, the fitting shape of the valve body 2 and the valve body lid 4 is asymmetrical with respect to the midpoint of the mounting position of the two screws 6 so that the mounting can be performed only at the correct relative position during assembly. It is possible.

これらの構成は、前記弁本体２と前記弁体蓋４、及び前記弁体蓋４と前記動力源５の相対位置が一意的に決まり、誤取付け等の組立上の不具合を予防することを目的とするものだが、この構成と形状の限りではない。   These configurations are intended to prevent assembly problems such as incorrect mounting, because the relative positions of the valve body 2 and the valve body lid 4 and the valve body lid 4 and the power source 5 are uniquely determined. However, it is not limited to this configuration and shape.

組立時には、前記弁本体２に前記弁体３を挿入し、前記動力源５を組み付けた前記弁体蓋４をはめ込み、前記止め輪７を前記弁本体２に挿入し、前記動力源５を組み付けた前記弁体蓋４が外れないようにすることで、制御弁１を組み立てることができる。   At the time of assembly, the valve body 3 is inserted into the valve body 2, the valve body cover 4 assembled with the power source 5 is fitted, the retaining ring 7 is inserted into the valve body 2, and the power source 5 is assembled. Further, the control valve 1 can be assembled by preventing the valve body lid 4 from being removed.

部品交換時には、前記止め輪７を前記弁本体２から取り外し、前記動力源５を組み付けた前記弁体蓋４を取り外すことで、該当故障部品を交換することができる。   At the time of parts replacement, the failed part can be replaced by removing the retaining ring 7 from the valve body 2 and removing the valve body cover 4 to which the power source 5 is assembled.

また、サービスパーツとして前記動力源５を組み付けた前記弁体蓋４を用意しておくことで、ドライバーなどの工具を使わず前記止め輪７の着脱のみで、前記動力源５を容易に交換することが可能となる。   Further, by preparing the valve body lid 4 with the power source 5 assembled as a service part, the power source 5 can be easily replaced by simply attaching and detaching the retaining ring 7 without using a tool such as a screwdriver. It becomes possible.

図２は、１つの弁本体２に対し、２つの動力源５を搭載した制御弁１に本発明を適用した場合の断面図である。   FIG. 2 is a cross-sectional view when the present invention is applied to a control valve 1 having two power sources 5 mounted on one valve body 2.

制御弁は２つの制御弁の弁本体、及び、各種接続継手などを集約することで、部品点数削減によるコストダウン、省スペース化を図ったものだが、一般的な１つの動力源を有する制御弁に対し、２つの動力源を有する制御弁は、弁本体が２つの動力源と共用であり、さらに従来の仕様では１つの動力源が故障した際でも弁本体を交換する必要があったため、動力源の故障の際には弁本体のみならず、正常な他の動力源も交換しなければならなかった。   The control valve integrates the valve body of the two control valves and various connecting joints to reduce costs and save space by reducing the number of parts. However, the control valve has a common single power source. On the other hand, in the control valve having two power sources, the valve body is shared with the two power sources, and in the conventional specification, it is necessary to replace the valve body even when one power source fails. In the event of a source failure, not only the valve body but also other normal power sources had to be replaced.

なおかつ、２つの動力源を有する制御弁の弁本体は、複数の機能を満足する必要があるため、複雑な構成になることが多く、弁本体の価格は高くなりやすい。   Moreover, since the valve body of the control valve having two power sources needs to satisfy a plurality of functions, the valve body often has a complicated configuration, and the price of the valve body tends to be high.

よって、一体化混合弁においてはサービスパーツのコストが高くなりやすいのである。   Therefore, in the integrated mixing valve, the cost of service parts tends to increase.

本発明を適用した制御弁１においては、１つの動力源５が故障した際は、対象の動力源５と、弁体蓋４をセットで交換するだけでよく、サービスパーツのコストを大幅に削減することが可能である。   In the control valve 1 to which the present invention is applied, when one power source 5 breaks down, it is only necessary to replace the target power source 5 and the valve body lid 4 as a set, thereby greatly reducing the cost of service parts. Is possible.

これらの構成は、２つの動力源を搭載した制御弁に対し、サービスパーツのコストを削減することを目的とするものであるが、動力源の員数、弁本体の形状はこの限りではない。   These configurations are intended to reduce the cost of service parts for a control valve equipped with two power sources, but the number of power sources and the shape of the valve body are not limited to this.

本発明の制御弁は、制御弁を有するあらゆる機器への転用が可能であり、例えば、給湯機、温水暖房機などの温水機器に幅広く適用することができる。   The control valve of the present invention can be diverted to any equipment having a control valve, and can be widely applied to hot water equipment such as a hot water heater and a hot water heater.
