本考案は、大形ビルに設置された受水槽に市町
村水道本管から給水するため給水装置に係り、特
に水道本管から受水槽に直接給水できるようにし
たものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a water supply device for supplying water from a municipal water main to a water tank installed in a large building. It is designed to provide water.
水道水を大量に使用する大形ビル等にあつて
は、水使用量に応じた容量受水槽を建物地階の２
階又は３階に設置し、この受水槽から各階の必要
場所へポンプアツプして給水するようになつてお

止水弁及び量水器を通して行なわれる。
In the case of large buildings that use a large amount of tap water, a water tank with a capacity corresponding to the amount of water used should be installed in the basement of the building.
It is installed on the first or third floor, and water is pumped up from this water tank to the necessary places on each floor.Water is also supplied to the water tank from the municipal water mains through a water stop valve and water meter. It can be done.
然るに、夏場のように水の需要量が増大する時
期では、水道本管の水圧が低下するが、この場
合、建物の地下２階以下に設置された受水槽は水

の端末需要者にあつては、水圧の低下に伴い水の
出が悪くなる。 However, during seasons when water demand increases, such as in the summer, the water pressure in the water mains decreases, but in this case, the water tank installed below the second basement floor of a building is lower than the underground level of the water mains. Since the level is quite low, the water head level difference allows relatively sufficient water supply to the water mains. In contrast,
For small users of terminals such as general households in areas surrounding buildings equipped with water tanks, water flow becomes poor due to the drop in water pressure.
そこで、市町村の水道局では、建物の１階もし
くは地下１階に副受水槽を設置し、この副受水槽
に一旦貯留した水を主受水槽へ供給するシステム
を採用するように指導している。 Therefore, municipal waterworks bureaus are instructing people to install a sub-water tank on the first floor or basement floor of a building, and to adopt a system in which the water stored in this sub-tank is supplied to the main tank. .
第４図は、このような従来における受水槽への
給水システムを示す。 FIG. 4 shows such a conventional water supply system to a water tank.

ことなく上下方向に安定に案内させる。 Inside the housings 12 and 13, which are joined to each other, there is a ball-shaped valve body 16 having a desired weight and having a larger diameter than the inner diameter of the inlet 15, which is floated up and down by the water pressure flowing from the water main 6 through the inlet 15. is located. This ball-shaped valve body 16 has a spherical cavity 16a inside, and by eccentrically moving the cavity 16a upward, the center of gravity of the valve body 16 is located below the center position, thereby stabilizing the posture when floating vertically. It's starting to become more and more. In addition, the valve body 1
A pair of guide rods 17a, 17b and 18 are provided at the center of the upper and lower surfaces of the rod 6, extending upwardly and downwardly.
One ends of the guide rods 17a and 18b are fixed, and the other ends of the guide rods 17a and 17b are engaged with the center cross portion of a cross-shaped holding member 19 installed horizontally within the upper housing 12, as shown in FIG. At the same time, the other end portions of the other guide rods 18a and 18b are engaged with the center cross portion of a cross-shaped holding member 20 installed horizontally within the inlet 15 of the lower housing 13, thereby preventing the valve body 16 from oscillating laterally. To stably guide in the vertical direction without causing any movement.

成するための突部２２が複数設けられている。 Further, on the inner surface of the inlet 15, there is a protrusion 22 for forming a gap 21 that can ensure the minimum required water supply even if the valve body 16 engages with the inlet 15 as the inflow water pressure decreases. There are multiple locations.
次に、上記のように構成された本実施例の動作
について説明する。 Next, the operation of this embodiment configured as described above will be explained.

る。 When the water stop valve 8 is opened, an amount of water corresponding to the opening degree of the water main pipe 6 flows into the water control valve 11 through the branch pipe 7, the water stop valve 8, and the water meter 9. Accordingly, the inflow water pressure acting on the valve body 16 from the inlet 15 causes the valve body 16 to move upward in the direction of arrow A in FIG. 2, thereby fully opening the inlet 15. At this time, if the water pressure in the water main pipe 6 is normal water pressure (2 to 3 kg/cm 2 ), the position of the valve body 16 is approximately as shown by the solid line in FIG. hold it fully open.
従つて、制水弁１１のハウジング１２，１３内

なくなるので、弁体１６は自重で下降し、流入口
１５内の突部２２と係合した状態に保持される。 Therefore, water flowing into the housings 12 and 13 of the water control valve 11 is supplied into the water receiving tank 1 from the outlet 14 through the pipe 4 and the ball tap 5. When the water level in the water tank 1 reaches a set level, the ball tap 5 closes and water supply to the water tank 1 is stopped. As a result, the inflow water pressure disappears, so the valve body 16 descends under its own weight and is held in a state where it is engaged with the protrusion 22 in the inflow port 15.
一方、夏期等の大量の水需要期に入つて、水道

る。 On the other hand, when the water pressure in the water main 6 falls below 1 to 1.5 kg/cm 2 during periods of high water demand such as summer, the inflow water pressure through the inlet 15 is necessary to raise and float the valve body 16. Valve body 1
6 descends as shown by the dashed line in FIG. 2 and engages with the protrusion 22 of the inlet 15, closing the inlet 15 leaving a gap 21 formed by the protrusion 22. This eliminates the siphon phenomenon between the water tank 1 and the water main pipe 6 and prevents water from the water main pipe 6 from being sucked in, while at the same time ensuring the minimum necessary water supply to the water tank 1 through the gap 21. I will do it.

The upward movement caused by the inflow pressure is restricted to prevent the outlet port 14 from being blocked.

Since the water supplied from the water main 6 to the water tank 1 is automatically controlled according to changes in water pressure within the water main 6, there is no need for a sub-water tank as in the past. The installation space can be used effectively and the initial cost of the water supply system can be significantly reduced.

Guide rods 17a, 17b and 18a, 18b
Although the case where the guide mechanism is used has been described, the present invention is not limited to this, and other guide mechanisms may be used. Also, even if the above-mentioned guide mechanism is omitted,
A certain degree of stability can be achieved simply by providing the eccentric cavity 16a within the valve body 16.
