(57) [Abstract] [Purpose] We propose a device that can be used as a supply path for tap water to a building or the like and that can easily increase the water pressure in the supply path. [Composition] A pressurizing pump having a single blade whose blade extends spirally in the axial direction is provided in the middle of the tap water supply path. The water pressure in the supply channel can be easily increased, and this can be compensated for when water pressure is insufficient in long-distance water supply or high-rise buildings. Therefore, it is possible to eliminate a water storage tank conventionally installed on the roof of a building or the like, or a multi-stage pump installed under the building or the like.
Description
【0001】[0001]
この考案は、上水道あるいはビルの配水装置の改良に関する。 The present invention relates to improvement of a water supply system or a water distribution system for a building.
【0002】[0002]
例えば、ビルの配水には、屋上等にタンクを設置し、その自然水頭でビル内に 配水している。また、ビルの配水では、その地下室等に高揚程の多段ポンプを設 置して配水している。 For example, for water distribution in a building, a tank is installed on the rooftop and the natural water head distributes water to the inside of the building. In addition, in the water distribution of the building, a multistage pump with a high head is installed in the basement etc. to distribute water.
【0003】[0003]
然しながら、上述の屋上等にタンクを設置するものでは、タンクに揚水しなけ ればならず、特に、タンク内では水の流動が少ないので、タンクの汚れやこれに 伴う水の汚れの問題がある。また、多段ポンプは、製作するにも設置するにも構 造が複雑で高価となる難点がある。 However, in the case of installing the tank on the rooftop, etc., the water must be pumped into the tank, and in particular, there is little flow of water in the tank, so there is a problem of contamination of the tank and accompanying water contamination. . In addition, the multi-stage pump is complicated in structure and expensive to manufacture and install.

この考案は、上述のような課題を解決し得るものであって、その要旨とすると ころは、貯水池あるいは、上水道主管に一端が連結された水道管路の中途部に加 圧ポンプを設置し、その加圧ポンプの羽根をその回転軸芯方向に延伸する螺旋状 の一枚羽根としたものである。この螺旋状の一枚羽根は、その送水量等必要に応 じて複数枚用いてもよい。その場合、回転軸の周方向に均等に位相をずらせて設 ければよい。 This invention can solve the above problems, and its gist is to install a pressure pump in a reservoir or in the middle of a water pipe whose one end is connected to the main water supply pipe. The blade of the pressure pump is a spiral single blade extending in the direction of the axis of rotation. A plurality of spiral single blades may be used depending on the water supply amount and the like. In that case, the phase may be evenly shifted in the circumferential direction of the rotating shaft.
【0005】[0005]
この考案に係る配水装置は、上述のように構成してあるので、例えば、ビルの 高所の階に送水する場合、その送水管路に加圧ポンプを設置することによって、 その送水圧力を高めることができる。従って、例えば、ビルの各階に送水する場 合、ビルの引込管にこの加圧ポンプを設置することによって、受水の圧力を高め ることができ、高所の階でも高圧力の水を得ることができる。また、貯水池から 遠距離にあって、圧力の低下した管に設置すれば、その圧力を簡単に高めること ができる。この場合、設置する加圧ポンプの羽根の数は、小径の送水パイプの場 合は、一枚でよく、大径の送水パイプの場合は、その総水量に対する体積効率を 勘案して複数枚とすればよい。また、この場合の昇圧できる圧力は、羽根の形状 にもよるが1〜3kg/cm2である。以下、図面に基づいて、この考案を具体的に説 明する。 Since the water distribution device according to the present invention is configured as described above, for example, when water is sent to a high floor of a building, a pressure pump is installed in the water supply line to increase the water supply pressure. be able to. Therefore, for example, when sending water to each floor of a building, installing this pressurizing pump in the intake pipe of the building can increase the pressure of water received, and obtain high-pressure water even on high floors. be able to. If the pipe is installed far away from the reservoir and the pressure drops, the pressure can be easily increased. In this case, the number of blades of the pressurizing pump to be installed may be one in the case of a small diameter water pipe, and may be multiple in the case of a large diameter water pipe in consideration of the volume efficiency with respect to the total amount of water. do it. The pressure that can be increased in this case is 1 to 3 kg / cm2, depending on the shape of the blade. The present invention will be specifically described below with reference to the drawings.

図1は、送水管路に継足した加圧ポンプの縦断面図を示し、図中、符号1は吐 出ケーシング、2は揚水管、3,4は吐出ボール、5は吸込カバー、6は羽根車 、7はモーター、8は、モーター7への配電線、9は加圧ポンプの吸込側に接続 された送水管、10は同じく吐出側に接続された送水管である。 FIG. 1 is a vertical cross-sectional view of a pressurizing pump connected to a water supply line. In the figure, reference numeral 1 is a discharge casing, 2 is a pumping pipe, 3 and 4 are discharge balls, 5 is a suction cover, and 6 is a suction cover. An impeller, 7 is a motor, 8 is a distribution line to the motor 7, 9 is a water pipe connected to the suction side of the pressurizing pump, and 10 is a water pipe also connected to the discharge side.
【0007】 次に、上記羽根車6の羽根の構成を図1〜図4に基づいて説明する。この羽根 6は、斜流ポンプ等において、ボス部に分割して配設されている遠心羽根をその 回転軸方向に継足して螺旋状の一枚羽根としたものである。図2はその正面図で あり、図3はその展開図である。このように数枚の遠心羽根を継足することによ って、数個の遠心羽根を周方向に分割して配置したものに比較して数倍の加圧能 力を有するものである。尚、図示のものは、この羽根6を吸込カバー5に沿わせ て全体として円錐状に構成し、そのボス部も円錐状にしている。また、図4は、 上述のように構成した螺旋状の一枚羽根6を180度位相をずらせて二枚組み合 わせたものであり、大径の送水管の場合には、このように羽根の枚数を増加して 用いる。Next, the structure of the blades of the impeller 6 will be described with reference to FIGS. 1 to 4. In the mixed flow pump or the like, the blade 6 is a spiral single blade obtained by adding centrifugal blades, which are divided and arranged in the boss portion, in the direction of the rotation axis. 2 is a front view thereof, and FIG. 3 is a development view thereof. By adding several centrifugal blades in this way, the pressurizing ability is several times as high as that of several centrifugal blades arranged in the circumferential direction. In the illustrated case, the blade 6 is formed in a conical shape as a whole along the suction cover 5, and the boss portion thereof is also a conical shape. Further, FIG. 4 shows two spiral single blades 6 constructed as described above, which are combined 180 degrees out of phase with each other. Increase and use the number of.
【0008】 この考案に係る装置は上述のように構成してあり、加圧ポンプを駆動すること によって送水管9の水は、羽根6によって加圧されて送水管10に吐出する。す なわち、加圧された分だけ水頭が与えられるわけであり、従って、例えば、この 加圧ポンプをビルの引込管に設置すれば、低ヘッドに送られた水をビルの高所に まで送水することができる。また、この加圧ポンプを長距離の送水管路に用いる 場合には、長距離送水による水頭ロスを補うことができる。The device according to the present invention is configured as described above, and by driving the pressurizing pump, the water in the water supply pipe 9 is pressurized by the blades 6 and discharged to the water supply pipe 10. That is, the head is given only by the amount of pressure, so if this pressurizing pump is installed in the intake pipe of a building, for example, the water sent to the low head will reach the height of the building. Water can be sent. In addition, when this pressurizing pump is used for long-distance water supply pipelines, head loss due to long-distance water supply can be compensated.
【0009】[0009]
このように、この考案に係る装置によれば、送水管路の圧力不足を簡単に補う ことができるのであり、特に、この考案ではその加圧ポンプをその羽根がその回 転軸芯方向に伸びるラインポンプとしたので、設置するにも単に送水管に継足す るだけで足り、特別にポンプ設置室等は不要である。また、ビルの配水に用いる 場合には、従来、屋上に設けたタンクや地下に設けた多段ポンプは不要となる等 、実用上得られる利益は著大なものである。 As described above, according to the device of the present invention, it is possible to easily compensate for the lack of pressure in the water supply pipe. Particularly, in the present invention, the pressurizing pump has its blades extending in the direction of the axis of rotation. Since it is a line pump, it can be installed simply by adding it to the water pipe, and no special pump installation room is required. In addition, when it is used for water distribution in buildings, tanks on the roof and multi-stage pumps in the basement are no longer required, and the profits obtained in practice are enormous.
