Description

本発明は、水道等液体の配水管の管理及び、出水口を制御するウオーターハンマー防止機能付止水栓に関する。The present invention relates to a water faucet with a water hammer prevention function that controls a water distribution pipe for liquid such as water and controls a water outlet.

従来、ウオータハンマーの防止には、止水栓にて発生したウオーターハンマー現象を吸収消滅させるウオーターハンマー防止器を使用する。（特許文献１）
また、ウオーターハンマーの発生しない程度の流水量の止水栓を採用するか、止水栓の流水量及び閉止速度を人為的に調整してウオーターハンマーを防止いている。
特許公開２００３−０６５４８４号公報 Conventionally, to prevent a water hammer, a water hammer preventer that absorbs and extinguishes the water hammer phenomenon generated by the water stop cock is used. (Patent Document 1)
In addition, a water stopcock with a water flow amount that does not generate a water hammer is employed, or the water hammer flow rate and the closing speed are artificially adjusted to prevent the water hammer.

本発明はウオーターハンマーを発生させない止水栓であるので、ウオーターハンマー防止器、防止装置等を必要としない。Since the present invention is a water stop cock that does not generate a water hammer, it does not require a water hammer prevention device, a prevention device, or the like.

各市町村及び戸建、集合住宅、企業、工場等水源及び給水方法による相違及び、液体の種類により水圧・流速が異なるので、個々の末端の蛇口各種水栓等の手前にウオーターハンマー防止装置の設置、水圧、流速を調整又は、閉栓速度に注意しウオーターハンマーの防止対策としている。Water hammer prevention devices are installed in front of various faucets and other faucets because the water pressure and flow rate vary depending on the water source and water supply method, etc. of each municipality, detached house, apartment house, company, factory, etc. The water pressure and flow rate are adjusted or the water clogging speed is taken into consideration to prevent water hammer.

水道等液体の配管及び、止水栓、蛇口等に採用できるウオーターハンマー防止機能を備えた止水栓である。This is a water stop cock with a water hammer prevention function that can be used for water pipes, water taps, faucets, etc.

従来のウオーターハンマー防止器等は、発生したウオーターハンマー現象を減少又は吸収消滅させるのが目的であるが、本発明は、ウオーターハンマーを発生させない構成なので、防止器等を必要としない。The conventional water hammer prevention device or the like is intended to reduce or eliminate the generated water hammer phenomenon, but the present invention does not require a prevention device or the like because it does not generate a water hammer.

配管の制御に採用する場合は、管の内断面積と同じ断面積の弁座３及びそれに対応した弁体２を採用する事により、流水の抵抗は皆無に近いものと思われる。When adopting for the control of piping, it is considered that the resistance of running water is almost zero by adopting the valve seat 3 having the same cross-sectional area as the inner cross-sectional area of the pipe and the valve body 2 corresponding thereto.

本発明は、給水の減圧も必要なく給水路にはなんら抵抗のない構成なので、常時全開の吐水が可能の状態が維持できる。Since the present invention does not require any depressurization of the water supply and has no resistance in the water supply channel, it is possible to maintain a state in which water can be fully opened at all times.

本体１の吐出口１０とシングルレバー又は２ハンドル混合栓の吐出口に継手を介して接続し駆動源１２が手動の場合、指先等で押すレバー先端を吐出口１１の近くに配置する。
そのレバーを指先又は、コップ等容器で押すと作動軸４が、前進弁体２を移動させ吐水する。混合栓で適温に調整しておくと常時一定の温度の水を出すことが出来る。When the drive source 12 is manually connected to the discharge port 10 of the main body 1 and the discharge port of the single lever or the two-handle mixing plug and the drive source 12 is manual, the lever tip pushed by the fingertip or the like is arranged near the discharge port 11.
When the lever is pushed with a fingertip or a container such as a cup, the operating shaft 4 moves the forward valve body 2 to discharge water. If the temperature is adjusted to an appropriate temperature with a mixing stopper, water at a constant temperature can be discharged at all times.

本体１を管末の接続部に装着、駆動源１２に電磁力・電動機等を用い制御に電子回路を採用するとウオーターハンマー防止機能付自動水栓となる。When the main body 1 is mounted on the connection portion of the pipe end, an electromagnetic circuit, an electric motor or the like is used as the drive source 12 and an electronic circuit is adopted for control, an automatic water faucet with a water hammer preventing function is obtained.
