Description

本発明は、河川、防火水槽等から吸水する消防ポンプ自動車等に使用される消防用ポンプに関するものである。   The present invention relates to a fire pump used for a fire pump automobile that absorbs water from a river, a fire prevention water tank or the like.

従来、消防用ポンプは、ポンプ本体の真空ポンプが吸水導管側にのみ吸引管で連通され、この吸引管の途中にフロースイッチ、逆止弁、止水弁が設けられ、吸水には消防ポンプ自動車に装備された真空ポンプにより、主ポンプ及び吸水導管内の空気を排出することにより行っているのが一般的であった。   Conventionally, a fire pump has a vacuum pump connected to the suction pipe only on the suction pipe side, and a flow switch, check valve, and stop valve are provided in the middle of the suction pipe. In general, the vacuum pump is installed to discharge the air in the main pump and the water intake conduit.

この場合、放水口自動逆止弁が主ポンプと放水口自動逆止弁側との境界を閉塞し、主ポンプ及び吸水導管内は真空となり吸水が行われる。
一方、この放水口自動逆止弁の作用により、放水口自動逆止弁から放水コックにいたる放水導管内の空気は排除されないので残留した状態となる。
このため、ホースの延長が完了し放水コックを開き放水を行った時、この排出されなかった残留空気が主ポンプに逆流し、場合によっては落水にいたり放水不能となり、消火活動に遅れを生じることがある。
又、例え放水されても、最初の放水は残留空気と水が混じり、放水が不安定となる問題点を有していた。 In this case, the water outlet automatic check valve closes the boundary between the main pump and the water outlet automatic check valve, and the main pump and the water intake conduit are evacuated to absorb water.
On the other hand, due to the action of the water discharge port automatic check valve, air in the water discharge conduit from the water discharge port automatic check valve to the water discharge cock is not excluded and remains.
For this reason, when extension of the hose is completed and the water discharge cock is opened and the water is discharged, the residual air that has not been discharged will flow back to the main pump, and in some cases it may fall into water or be unable to discharge, resulting in a delay in fire fighting activities. There is.
Even if the water is discharged, the first water discharge has a problem that residual air and water are mixed and the water discharge becomes unstable.

そこで、この問題点を解決するために、本出願人はポンプ本体の真空ポンプと吸水側及び真空ポンプと放水口自動逆止弁から放水コックにいたる放水側の双方を吸引管で連通し、この構成により吸水導管から放水導管にいたる残留空気を排出し、真空状態すれば水は主ポンプを介して放水コックまで充満されるから、放水始めで放水が不安定となることもなく、確実な放水を可能とした消防用ポンプを発明し、特許第３５８６３９２号として既に登録されている。
特許第３５８６３９２号 Therefore, in order to solve this problem, the applicant communicates both the vacuum pump of the pump body and the water absorption side and the water discharge side from the vacuum pump and the water discharge automatic check valve to the water discharge cock with a suction pipe. By discharging the residual air from the water intake pipe to the water discharge pipe according to the configuration, if it is in a vacuum state, the water will be filled up to the water discharge cock via the main pump. Has been invented and has already been registered as Japanese Patent No. 3586392.
Japanese Patent No. 3586392

本発明は、上記特許発明の消防用ポンプに更に改良を加え、揚水が完了して放水コックを開き放水を行う時に、放水口自動逆止弁から放水コックにいたる放水側に真空ポンプの吸引作用で完全に排気されなかった残留空気、及び揚水と一緒に侵入した残留空気までも悉く除去し、これにより最初の放水時に残留空気が混ざることなく、安定したより確実な放水を可能とした消防用ポンプを提供しようとするものである。   The present invention further improves the fire pump of the above-mentioned patented invention, and when pumping is completed and the water discharge cock is opened to discharge water, the suction action of the vacuum pump on the water discharge side from the water discharge automatic check valve to the water discharge cock Residual air that has not been completely exhausted in the air, and residual air that has intruded with the pumped water are removed brilliantly, so that residual air is not mixed at the time of the first water discharge, enabling stable and reliable water discharge. Is to provide a pump.

上記課題を解決するため、請求項１記載の本発明消防用ポンプは、ポンプ本体の真空ポンプと吸水側が止水弁又は逆止弁を有する吸水側吸引管で連通されると共に、前記真空ポンプと放水口自動逆止弁から放水コックにいたる放水側とが放水側吸引管で連通している消防用ポンプにおいて、放水側吸引管に止水用電動バルブが設けられると共に、この止水用電動バルブの下流側で放水側吸引管に排気用チャッキバルブを介して排気管が設けられ、前記止水用電動バルブは制御手段により真空ポンプの停止後に、遅延して閉鎖することを特徴とするものである。   In order to solve the above-mentioned problem, the fire fighting pump according to the first aspect of the present invention is configured such that the vacuum pump of the pump body and the water suction side are communicated with a water suction side suction pipe having a water stop valve or a check valve, and the vacuum pump In a fire-fighting pump in which the water discharge side from the water discharge automatic check valve to the water discharge cock communicates with the water discharge side suction pipe, the water discharge side suction pipe is provided with a water stop electric valve, and this water stop electric valve An exhaust pipe is provided on the discharge side suction pipe via an exhaust check valve on the downstream side, and the water stop electric valve is closed with a delay after the vacuum pump is stopped by the control means. is there.

このような構成とすることにより、真空ポンプの始動でポンプ本体の吸水側と放水側の双方の配管から残留空気は吸引され、水は放水コックまで充満されるが、この吸引により完全に排気されなかった残留空気及び水と一緒に侵入した空気は真空ポンプの停止により放水側の配管内に残留空気として僅かに残るが、止水用電動バルブが制御手段により真空ポンプの停止後に遅延して閉鎖するため、真空ポンプの停止後も止水用電動バルブが閉鎖されるまでの間は、放水側の配管内の残留空気は放水側吸引管から止水用電動バルブを経て、排気用チャッキバルブにより排気管を通って外部へ自然に排気される。   With such a configuration, when the vacuum pump is started, residual air is sucked from both the water intake side and the water discharge side pipes of the pump body, and the water is filled up to the water discharge cock. Residual air and air that has entered together with water remain slightly in the water discharge piping as residual air due to the stop of the vacuum pump, but the water stop valve is closed after the vacuum pump is stopped by the control means Therefore, until the water stop electric valve is closed after the vacuum pump is stopped, the residual air in the water discharge side pipe passes from the water discharge side suction pipe to the water stop electric valve, and then reaches the exhaust check valve. It is naturally exhausted to the outside through the exhaust pipe.

次に、請求項２記載の本発明消防用ポンプは、請求項１記載の消防用ポンプにおいて、制御手段はタイマーであることを特徴とするものである。   Next, the fire fighting pump of the present invention according to claim 2 is characterized in that, in the fire fighting pump according to claim 1, the control means is a timer.

このような構成とすることにより、時間の設定が容易である。   With such a configuration, time setting is easy.

請求項１記載の本発明消防用ポンプによれぱ、真空ポンプの吸引作用で完全に排気されなかった残留空気や、揚水が完了して最初の放水を行う時に水と一緒に侵入した空気は真空ポンプの停止により放水側の配管内に残留空気として僅かに残るが、止水用電動バルブが制御手段により真空ポンプの停止後に遅延して閉鎖するため、真空ポンプの停止後も止水用電動バルブが閉鎖されるまでの間は、残留空気は放水側吸引管から止水用電動バルブを経て排気用チャッキバルブにより悉く排気管から外部へ自然に排気されるので、残留空気が全く混ざらない理想的な揚水となる。これにより最初の放水時に安定した確実な放水が可能となる効果を有する。   According to the fire-fighting pump of the present invention, the residual air that has not been completely exhausted by the suction action of the vacuum pump or the air that has entered with the water when pumping is completed and the first water discharge is performed is vacuum. Although the residual air remains slightly in the water discharge side pipe due to the stop of the pump, the water stop electric valve is delayed and closed after the vacuum pump is stopped by the control means, so the water stop electric valve even after the vacuum pump stops Until the air is closed, the residual air is naturally exhausted from the exhaust pipe drawn by the exhaust check valve through the water stop electric valve from the discharge side suction pipe, so that the residual air is not mixed at all. Water pumping. This has the effect of enabling stable and reliable water discharge during the first water discharge.

次に、請求項２記載の本発明消防用ポンプによれば、時間の設定が容易で、確実に作動する効果を有する。   Next, according to the fire fighting pump of the present invention, it is easy to set time and has an effect of operating reliably.

前記、放水口自動逆止弁７は弁筐１５の上部に弁１６の横断面が多角形（５角形）の弁棒１７が摺動する円筒状の弁棒摺動用中空部１８を有する蓋体１９が設けられている。又弁棒摺動用中空部１８の頂部に孔２０が穿設されている。
尚、図中２１は弁棒１７の基部に設けた止水用パッキンであり、弁１６の上昇で弁棒摺動用中空部１８の内側口端縁と弁棒１７の外周面との間隙を閉塞する。 The water outlet automatic check valve 7 has a cylindrical valve stem sliding hollow portion 18 on which a valve rod 17 having a polygonal (pentagonal) cross section of the valve 16 slides at the top of a valve housing 15. 19 is provided. A hole 20 is formed in the top of the valve rod sliding hollow portion 18.
In the figure, reference numeral 21 denotes a water stop packing provided at the base of the valve stem 17, and the gap between the inner edge of the valve stem sliding hollow portion 18 and the outer peripheral surface of the valve stem 17 is closed by raising the valve 16. To do.

これにより、放水口自動逆止弁７から放水コック８にいたる放水導管９の残留空気は、横断面が多角形の弁棒１７の外壁と円筒状の弁棒摺動用中空部１８の内壁との摺動面の間隙を通じて孔２０から排出可能となる。   Thereby, the residual air of the water discharge conduit 9 from the water discharge automatic check valve 7 to the water discharge cock 8 is formed between the outer wall of the valve rod 17 having a polygonal cross section and the inner wall of the cylindrical valve rod sliding hollow portion 18. It becomes possible to discharge from the hole 20 through the gap of the sliding surface.

放水側は、この弁棒摺動用中空部１８の頂部に放水側吸引管２２ａと、放水導管９に放水側吸引管２２ｂの一端が連結されて、この両放水側吸引管２２ａ、２２ｂの他端は三方チーズ２３でそれぞれ放水側連結吸引管２２ｃに連結され、放水側連結吸引管２２ｃは吸水側吸引管１０と合流吸引管１１の接続部に設けた三方チーズ２４に接続し、合流吸引管１１を介して真空ポンプ３の吸気口３ａと連通している。   On the water discharge side, a water discharge side suction pipe 22a is connected to the top of the valve rod sliding hollow portion 18, and one end of the water discharge side suction pipe 22b is connected to the water discharge conduit 9, and the other ends of the water discharge side suction pipes 22a and 22b. Are connected to the water discharge side connection suction pipe 22c by the three-way cheese 23, and the water discharge side connection suction pipe 22c is connected to the three-way cheese 24 provided at the connection portion between the water absorption side suction pipe 10 and the merging suction pipe 11, and the merging suction pipe 11 is connected. And communicates with the intake port 3a of the vacuum pump 3.

弁棒摺動用中空部１８の頂部と連結する放水側吸引管２２ａの途中が三方チーズ２５で分岐され、この三方チーズ２５に排気用チャッキバルブ２６を介して外部に開口する排気管２７が接続されている。   A water discharge side suction pipe 22a connected to the top of the valve rod sliding hollow portion 18 is branched by a three-way cheese 25, and an exhaust pipe 27 that opens to the outside is connected to the three-way cheese 25 via an exhaust check valve 26. ing.

放水導管９と連結する放水側吸引管２２ｂの途中に止水用電動バルブ２８が設けられている。この止水用電動バルブ２８は制御手段であるタイマー２９と連絡している。   A water stop electric valve 28 is provided in the middle of the water discharge side suction pipe 22 b connected to the water discharge pipe 9. The water stop electric valve 28 communicates with a timer 29 which is a control means.

このタイマー２９は真空ポンプ３の駆動部２と連絡し、真空ポンプ３が停止した時に、駆動部２の検知部３０から信号を送り、タイマー２９が真空ポンプ３の停止後、約２秒以内の範囲で止水用電動バルブ２８に信号を送り、遅延して止水用電動バルブ２８を閉鎖する。   This timer 29 communicates with the drive unit 2 of the vacuum pump 3 and when the vacuum pump 3 is stopped, a signal is sent from the detection unit 30 of the drive unit 2 and within about 2 seconds after the timer 29 stops the vacuum pump 3. A signal is sent to the water stop electric valve 28 within the range, and the water stop electric valve 28 is closed with a delay.

又、放水側連結吸引管２２ｃの途中に電動又は手動による逆止弁３１が設けられている。この逆止弁３１は吸水側逆止弁１３と同時に作動する。   In addition, an electric or manual check valve 31 is provided in the middle of the discharge side connection suction pipe 22c. This check valve 31 operates simultaneously with the water suction side check valve 13.

次に、このような構成を有する本発明消防用ポンプの作用を図面に基づき説明する。
真空ポンプ３の始動で吸水側は、真空ポンプ３と吸水側吸引管１０で連通している吸水導管６側からは従来通り、吸水導管６及び主ポンプ４内の空気は吸引され真空となる。この時、弁１６により放水導管９側への水路は閉塞されている。 Next, the operation of the fire pump according to the present invention having such a configuration will be described with reference to the drawings.
When the vacuum pump 3 is started, the water suction side is vacuumed by sucking the air in the water suction conduit 6 and the main pump 4 from the side of the water suction conduit 6 communicating with the vacuum pump 3 and the water suction suction tube 10 as usual. At this time, the water channel to the discharge pipe 9 side is closed by the valve 16.

一方、真空ポンプ３の始動で放水側は、弁棒摺動用中空部１８の頂部と連結している放水側吸引管２２ａと、放水導管９と連結している放水側吸引管２２ｂの両方から効率良く短時間で残留空気は吸引され殆ど真空となる。この時、放水コック８は閉じている。   On the other hand, when the vacuum pump 3 is started, the water discharge side is efficient from both the water discharge side suction pipe 22a connected to the top of the valve rod sliding hollow part 18 and the water discharge side suction pipe 22b connected to the water discharge pipe 9. Residual air is sucked in almost a short time and almost vacuumed. At this time, the water discharge cock 8 is closed.

このように、ポンプ本体１及び吸水コック５、吸水導管６が総て真空状態となり、主ポンプ部４に水は充満し弁１６を押し上げ、放水導管９内を通り放水コック８にいたる。   Thus, the pump main body 1, the water intake cock 5, and the water intake conduit 6 are all in a vacuum state, the main pump portion 4 is filled with water, the valve 16 is pushed up, and the water discharge conduit 9 is passed through to the water discharge cock 8.

吸水側吸引管１０は止水弁１４が流路を閉塞し、放水側の弁棒摺動用中空部１８と連結する放水側連結吸引管２２ａは弁１６が上昇し、止水パッキン２１が流路を閉塞し、放水導管９と連結する放水側吸引管２２ｂ及び放水側連結吸引管２２ｃは逆止弁３１と止水用電動バルブ２８が流路を閉塞し、水が真空ポンプ３内に侵入することは阻止される。   The water suction side suction pipe 10 has a water stop valve 14 closing the flow path, the water discharge side connection suction pipe 22a connected to the water discharge side valve rod sliding hollow portion 18 has the valve 16 raised, and the water stop packing 21 has a flow path. The water discharge side suction pipe 22b and the water discharge side connection suction pipe 22c connected to the water discharge pipe 9 are closed by the check valve 31 and the water stop electric valve 28, and water enters the vacuum pump 3. That is blocked.

そして、真空ポンプ３が停止すると真空ポンプ３の駆動部２の検知部３０が停止を検知し、制御手段であるタイマー２９に信号を送り、タイマー２９が真空ポンプ３の停止後、約２秒以内の範囲で作動し、止水用電動バルブ２８を閉鎖する。   When the vacuum pump 3 is stopped, the detection unit 30 of the driving unit 2 of the vacuum pump 3 detects the stop, and sends a signal to the timer 29 which is a control means. The timer 29 is within about 2 seconds after the vacuum pump 3 stops. The electric valve 28 for water stop is closed.

この真空ポンプ３の停止から止水用電動バルブ２８が閉鎖するまでの間に、放水側の放水導管９内の真空ポンプ３の吸引作用で排気されなかった残留空気及び揚水時に揚水中に含まれる空気は放水側吸引管２２ｂから止水用電動バルブ２８、三方チーズ２３、２５を通り、排気用チャッキバルブ２６により排気管２７から外部へ自然に排気される。これにより、放水側には残留空気が全く存在しなくなる。   From the stop of the vacuum pump 3 to the closing of the water stop electric valve 28, residual air that has not been exhausted by the suction action of the vacuum pump 3 in the water discharge conduit 9 on the water discharge side and is included in the pumped water during pumping Air passes through the water stop electric valve 28 and the three-way cheeses 23 and 25 from the water discharge side suction pipe 22b, and is naturally exhausted from the exhaust pipe 27 to the outside by the exhaust check valve 26. As a result, no residual air is present on the water discharge side.

以上、本発明の実施形態に基づき具体的に説明したが、本発明は上記実施形態に何ら限定されるものではなく、例えば放水側の吸引は弁棒摺動用中空部１８の頂部を閉鎖し、放水導管９と連結する側の放水側吸引管２２ｂからのみ構成とすることもできる等、本発明の趣旨を逸脱しない範囲内で種々の改良、変形が可能である。   The present invention has been specifically described above based on the embodiment of the present invention, but the present invention is not limited to the above embodiment. For example, the suction on the water discharge side closes the top of the hollow portion 18 for sliding the valve stem, Various improvements and modifications can be made without departing from the gist of the present invention, such as the construction of only the water discharge side suction pipe 22b connected to the water discharge pipe 9.
