Description
本発明は、フランジ及びそのフランジを用いたポンプ装置に関するものである。 The present invention relates to a flange and a pump device using the flange.
ポンプ装置は、ポンプ部と水源を接続する吸込フランジと、前記ポンプ部により揚水増圧された水を使用位置（蛇口等）まで接続する吐出フランジと、を備えており、配管の接続は主に施工業者によって行われる。そのため、配管継手（バルブソケット等）の材質（樹脂製または金属製）ならびに接続作業（ねじ込み量等）の管理は困難であり、配管継手が強固に接続された場合でも容易に破損しないよう、吸込フランジならびに吐出フランジの材質には主に強度や耐食性に優れる青銅やステンレスなどが用いられる。しかし、青銅やステンレスは原材料の高騰や加工費上昇の影響を受け易いため、製造コストが高くなる恐れがある。例えば、製造コストを抑える手段としてフランジの材質を合成樹脂にする方法が用いられる（特許文献１）。特許文献１には、フランジを樹脂材料で形成し配管接続部をテーパ形状（ねじ形状を用いず）にして接着剤により配管を接着する方法が記載されている。 The pump device includes a suction flange that connects the pump unit and the water source, and a discharge flange that connects the water boosted and pumped by the pump unit to a use position (faucet, etc.). Performed by a contractor. For this reason, it is difficult to manage the material (resin or metal) and connection work (screwing amount, etc.) of pipe joints (valve sockets, etc.), and suction to prevent easy damage even when the pipe joints are firmly connected. For the material of the flange and the discharge flange, bronze, stainless steel or the like having excellent strength and corrosion resistance is mainly used. However, since bronze and stainless steel are easily affected by soaring raw materials and increased processing costs, the production cost may increase. For example, as a means for reducing the manufacturing cost, a method of using a synthetic resin as a flange material is used (Patent Document 1). Patent Document 1 describes a method in which a flange is formed of a resin material, a pipe connection portion is tapered (without using a screw shape), and the pipe is bonded with an adhesive.
特許文献１に記載のように、製造コストを抑える手段としてフランジを樹脂材料にする方法があるが強度の不足が懸念される。また、ねじ部分に青銅やステンレスを用いて合成樹脂でインサート成形する方法は強度面で優れるが、ねじ部分に機械加工を要するため製造コストの大幅な低減は難しい。従って、安価で強度が優れるフランジ構造が必要である。 As described in Patent Document 1, there is a method of using a flange as a resin material as a means for suppressing the manufacturing cost, but there is a concern that the strength is insufficient. In addition, the method of insert molding with synthetic resin using bronze or stainless steel for the screw portion is excellent in strength, but since the screw portion requires machining, it is difficult to significantly reduce the manufacturing cost. Therefore, there is a need for a flange structure that is inexpensive and excellent in strength.
本発明は、青銅製やステンレス製のフランジと同等の高い強度や耐食性を有し、原材料ならびに製造コストが抑えられるフランジ及びそのフランジを用いたポンプ装置を提供することを目的とする。 An object of the present invention is to provide a flange having high strength and corrosion resistance equivalent to a flange made of bronze or stainless steel, and capable of suppressing raw materials and manufacturing costs, and a pump device using the flange.
本発明は、中央部に管用めねじを有し合成樹脂で形成される合成樹脂製フランジと、前記管用めねじの外周に固着される金属部材と、を有することを特徴とする。 The present invention is characterized by having a synthetic resin flange formed of a synthetic resin having a female thread for a pipe in the center, and a metal member fixed to the outer periphery of the female thread for a pipe.
本発明によると、青銅製やステンレス製のフランジと同等の高い強度や耐食性を有し、原材料ならびに製造コストが抑えられるフランジ及びそのフランジを用いたポンプ装置を提供することができる。 According to the present invention, a flange having high strength and corrosion resistance equivalent to a flange made of bronze or stainless steel, and a raw material and a manufacturing cost can be suppressed, and a pump device using the flange can be provided.
以下、本発明の実施形態を本発明の実施例の図面に沿って説明する。 Embodiments of the present invention will be described below with reference to the drawings of the embodiments of the present invention.
まず、本発明の合成樹脂製のフランジを備えるポンプ装置の概要について図１から図３を用いて説明する。図１は、本発明の一実例に係るもので、ポンプ装置１００の縦断面図である。図２は、図１の右側面図である。図２は合成樹脂製フランジ４０と金属部材４１からなるフランジ４２をポンプ装置１００に取り付けた右側面図であり、従来の青銅製あるいはステンレス製の吸込フランジならびに吐出フランジからの取替えも容易にできる。図３は、図１のポンプ装置１００からポンプカバー１０を外した状態の平面図である。 First, an outline of a pump device having a synthetic resin flange according to the present invention will be described with reference to FIGS. FIG. 1 is a longitudinal sectional view of a pump device 100 according to an example of the present invention. FIG. 2 is a right side view of FIG. FIG. 2 is a right side view in which a flange 42 made of a synthetic resin flange 40 and a metal member 41 is attached to the pump apparatus 100, and can be easily replaced with a conventional bronze or stainless steel suction flange and discharge flange. FIG. 3 is a plan view of the pump device 100 of FIG. 1 with the pump cover 10 removed.
ポンプ装置１００は、圧力タンク１と、この圧力タンク１の上に配置されたポンプ駆動用モータ２とポンプ駆動用モータ２の回転速度を変速させる速度制御装置が搭載された制御基板３とポンプ駆動用モータ２の上に配置され、ポンプ装置１００の吐出圧力値の表示や運転圧力等の設定を切替操作できる操作基板４が通信線で制御基板３と接続され、それらをポンプカバー１０が覆う構造である。 The pump device 100 includes a pressure tank 1, a pump driving motor 2 disposed on the pressure tank 1, a control board 3 on which a speed control device for changing the rotational speed of the pump driving motor 2 is mounted, and a pump driving. The operation board 4 arranged on the motor 2 and capable of switching the display of the discharge pressure value and the operation pressure of the pump device 100 is connected to the control board 3 by a communication line, and the pump cover 10 covers them. It is.
ポンプ部１５は、羽根車１６と、この羽根車１６を内置するケーシング１７と、ケーシング１７の前面を閉じるケーシングカバー１８を有しており、水源を接続する吸込フランジとして用いるフランジ４２、さらに前記ポンプ部により揚水増圧された水を使用位置（蛇口等）まで接続する吐出フランジとして用いるフランジ４２にそれぞれ吸込口６を有する吸込配管６ａならびに吐出口７を有する吐出配管７ａが接続される。 The pump unit 15 includes an impeller 16, a casing 17 in which the impeller 16 is disposed, a casing cover 18 that closes a front surface of the casing 17, a flange 42 that is used as a suction flange for connecting a water source, and the pump The suction pipe 6a having the suction port 6 and the discharge pipe 7a having the discharge port 7 are connected to the flange 42 used as a discharge flange for connecting the water whose pressure has been increased by the section to the use position (faucet or the like).
なお、本実施形態の説明は、代表的なポンプであるウェスコポンプを例示するが、本発明はウェスコポンプに限定されるものではない。 In addition, although description of this embodiment illustrates the Westco pump which is a typical pump, this invention is not limited to a Westco pump.
ポンプ装置１００の運転はポンプ駆動用モータ２を運転することにより行われる。まず、自吸運転が行われ、自吸運転が終了してから揚水運転に移行し、吐出配管７ａにつながる流路が閉じられると、吐出配管７ａから下流側の圧力が上がる。この圧力を圧力センサ５が検知してポンプ駆動用モータ２の運転が止まる。 The pump device 100 is operated by operating the pump drive motor 2. First, when the self-priming operation is performed and the self-priming operation is completed and then the pumping operation is performed and the flow path connected to the discharge pipe 7a is closed, the pressure on the downstream side increases from the discharge pipe 7a. The pressure sensor 5 detects this pressure and the operation of the pump driving motor 2 is stopped.
次に、本発明のフランジの構造について図４から図６を用いて説明する。 Next, the structure of the flange of the present invention will be described with reference to FIGS.
図４はフランジ４２の部品構成図である。フランジ４２は、中央部に管用めねじ４０ａを構成した合成樹脂製フランジ４０と、合成樹脂製フランジ４０の管用めねじ４０ａの外周壁４０ｂに固着する輪状の金属部材４１と、からなる。なお、金属部材４１には複数個の孔４１ａが設けてあるが、この機能については図５の説明で詳述する。 FIG. 4 is a component configuration diagram of the flange 42. The flange 42 includes a synthetic resin flange 40 having a pipe female screw 40a at the center, and a ring-shaped metal member 41 fixed to the outer peripheral wall 40b of the pipe female screw 40a of the synthetic resin flange 40. The metal member 41 has a plurality of holes 41a. This function will be described in detail with reference to FIG.
図５はフランジ４２の斜視図であり、金属部材４１を固着した状態である。金属部材４１の合成樹脂製フランジ４０への固着方法は、インサート成形の他、接着やアウトサート（圧入）等がある。固着方法によっては、市販のテーパおねじの配管継手（バルブソケット等）を接続する際に工具（パイプレンチ等）でつかむと回転力が加わり外れる恐れがある。また、前記配管継手が接続された状態で長期間放置状態となった場合、環境変化に伴うヒートサイクルを受けて外れてしまい破損に至る恐れがある。本実施形態では、インサート成形により金属部材４１に設けられた複数個の孔４１ａに樹脂を流入させピン状の突起４１ｂを形成することで、金属部材４１を合成樹脂製フランジ４０へ確実に固着できる構造としている。 FIG. 5 is a perspective view of the flange 42 in a state where the metal member 41 is fixed. As a method for fixing the metal member 41 to the synthetic resin flange 40, there are adhesion, outsert (press-fit) and the like in addition to insert molding. Depending on the fixing method, when connecting a commercially available taper male pipe joint (valve socket, etc.) with a tool (pipe wrench, etc.), rotational force may be applied and come off. Further, when the piping joint is connected and left in a long period of time, it may be detached due to a heat cycle accompanying an environmental change, leading to damage. In the present embodiment, the metal member 41 can be securely fixed to the synthetic resin flange 40 by forming the pin-like protrusion 41b by flowing resin into the plurality of holes 41a provided in the metal member 41 by insert molding. It has a structure.
図６はフランジ４２の片側断面図であり、金属部材４１の全長Ｌ２については詳述しないが、一般的な配管継手のおねじ３１ａは管用テーパねじで形成されており、合成樹脂製フランジ４０への接続（ねじ込み量）は配管継手の端部３１ｂからテーパおねじ基準径までの長さ寸法Ｌ１が基準となるため、合成樹脂製フランジ４０の強度確保のためＬ２＞Ｌ１としている。なお、本実施形態の説明において、金属部材４１は輪状を例示するが、金属部材４１は輪状に限定されるものではない。合成樹脂製フランジ４０の強度を向上するものであれば、一部切り欠きなどを有する形状でもよい。 FIG. 6 is a one-side cross-sectional view of the flange 42, and although the full length L2 of the metal member 41 is not described in detail, a general pipe joint male thread 31a is formed by a pipe taper thread, and is connected to the synthetic resin flange 40. Since the length dimension L1 from the end 31b of the pipe joint to the taper male thread reference diameter is a reference, L2> L1 is set to ensure the strength of the synthetic resin flange 40. In the description of the present embodiment, the metal member 41 is exemplified as a ring shape, but the metal member 41 is not limited to the ring shape. As long as the strength of the synthetic resin flange 40 is improved, the shape may be partially cut away.
これらにより、強度や耐食性で従来の青銅製やステンレス製のフランジと同様の機能を確保できるとともに、原材料ならびに加工費の製造コストが抑えられ、製品の安定供給に繋げることができる。 As a result, functions similar to those of conventional bronze or stainless steel flanges can be ensured in strength and corrosion resistance, and the manufacturing costs of raw materials and processing costs can be suppressed, leading to stable supply of products.
以上、圧力タンク付のポンプについて詳述してきたが、圧力タンクの無い、いわゆる非自動式ポンプのほか、ポンプと組み合わせ使用する水処理機器などの吸込口ならびに吐出口に本発明の合成樹脂製フランジを設けても同様の効果が得られるのはもちろんである。 As mentioned above, the pump with the pressure tank has been described in detail. In addition to the so-called non-automatic pump without the pressure tank, the synthetic resin flange of the present invention is used at the suction port and the discharge port of water treatment equipment used in combination with the pump Needless to say, the same effect can be obtained even by providing the above.
