本発明は管内に発生する水撃作用を利用して高
所に揚水する水撃ポンプに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a water hammer pump that pumps water to a high place by utilizing the water hammer action generated within a pipe.
低落差の水を利用して、この落差より高所へ揚
水するいわゆる水撃ポンプは電気等の動力源を必
要とせず、またその構造が簡単であるので低開発
国等で多く使用されている。
So-called water hammer pumps, which use water from a low head to pump water to a higher place than this head, do not require a power source such as electricity and have a simple structure, so they are often used in underdeveloped countries. .
従来より一般に使用されているこの種の水撃ポ
ンプについて、第２図を参照してその構造を説明
する。低落差H1の水源S1に上部で連通する導水
管１の下方の端部は弁室２に連通し、この弁室２
には内向きに開く排水弁３と外向きに開く揚水弁
４が備えられる。弁室２の上部には揚水弁４を介
して空気室５が設けられ、空気室５の下部に揚水
口７が開口し、高落差H1の位置において揚水部
S2に亘る揚水管６が設けられている。 The structure of this type of water ram pump, which has been commonly used in the past, will be explained with reference to FIG. The lower end of the water conduit 1 , whose upper part communicates with the water source S1 with a low head H1, communicates with the valve chamber 2.
is equipped with a drain valve 3 that opens inward and a pumping valve 4 that opens outward. An air chamber 5 is provided in the upper part of the valve chamber 2 via a pumping valve 4, and a pumping port 7 is opened in the lower part of the air chamber 5, and the pumping part is opened at the position of the height difference H1 .
A pumping pipe 6 extending over S 2 is provided.
これの動作について説明すると、排水弁３が開
揚水弁４が閉の状態で水源S1からの水が導水管１
内を流れ排水弁３から排出される。排水弁３から
排出される水の流速が速くなると排水弁３に揚水
力が作用して排出弁３が閉じる。その瞬間弁室２
の圧力は水撃作用により極めて高くなる。弁室２
の圧力が高くなると揚水弁４を押し上げ水流は揚
水弁４を通つて空気室５内に入り、そこで空気室
５内の空気を圧縮し、この空気圧により空気室５
内の水を揚水管６内に押し上げて、揚水部S2に供
給する。この作用により低落差H1に位置の水源
S1の水をより高落差H1の揚水部S2に押し上げて
供給できる。弁室２内の圧力は水撃作用によるも
のであるから次の瞬間には弁室２内の圧力は低下
し、若干の逆流によつて揚水弁４は閉じ、排水弁
３が開いて最初の状態にもどる。揚水弁４を閉じ
ている間も空気室５内の圧縮された空気により揚
水管６内の水は上昇する。 To explain the operation of this, when the drain valve 3 is open and the pumping valve 4 is closed, water from the water source S 1 flows into the water conduit pipe 1.
The water flows inside and is discharged from the drain valve 3. When the flow rate of water discharged from the drain valve 3 increases, a lifting force acts on the drain valve 3 and the drain valve 3 closes. At that moment valve chamber 2
The pressure becomes extremely high due to the water hammer effect. Valve chamber 2
When the pressure increases, the water flow pushes up the pumping valve 4 and enters the air chamber 5 through the pumping valve 4, where it compresses the air in the air chamber 5.
The water inside is pushed up into the pumping pipe 6 and supplied to the pumping section S2 . This action results in a water source located at a low head H1 .
The water in S1 can be pushed up and supplied to the pumping part S2 with a higher head H1 . Since the pressure inside the valve chamber 2 is due to the water hammer effect, the pressure inside the valve chamber 2 decreases in the next moment, the pumping valve 4 closes due to a slight backflow, and the drain valve 3 opens and the first Return to state. Even while the pumping valve 4 is closed, the water in the pumping pipe 6 rises due to the compressed air in the air chamber 5.
水撃ポンプは上記のように水撃作用を利用して
揚水するものであるから、衝撃的な圧力が弁類に
作用する。 Since the water hammer pump pumps water using the water hammer action as described above, an impulsive pressure acts on the valves.
特に、排水弁３には瞬間的に高い圧力が作用す
るので、排水弁３は、その圧力により生じる動作
が円滑であることが要求されると共に、優れた耐
久性が要求される。 In particular, since a high pressure is instantaneously applied to the drain valve 3, the drain valve 3 is required to operate smoothly due to the pressure, and is also required to have excellent durability.
第３図は従来より使用されている排水弁３の断
面図であつて、この図において、排水弁３は板状
の弁体８に弁軸９が垂直に固定されており、弁軸
９は軸受１０内を上下に移動可能に支持される。 FIG. 3 is a sectional view of a conventionally used drain valve 3. In this figure, the drain valve 3 has a valve shaft 9 vertically fixed to a plate-shaped valve body 8. It is supported to be movable up and down within the bearing 10.
弁体８の上面が弁座部１１に接した場合、排水
弁口１１′を閉じる。 When the upper surface of the valve body 8 comes into contact with the valve seat portion 11, the drain valve port 11' is closed.
今、弁室２内の圧力が上昇した時に、弁体８は
矢印Ａの方向に上昇するがその時、弁体８が水流
の条件により、傾斜して上昇することもあり、こ
の場合、弁の軸受１０及び弁軸９は無理な曲げが
作用し、軸受１０及び弁軸９が損傷を引き起すこ
とがある。また、弁軸９は軸受１０内を摺動する
為に、両者が摩耗する。 Now, when the pressure inside the valve chamber 2 increases, the valve body 8 rises in the direction of arrow A, but at that time, the valve body 8 may rise at an angle depending on the water flow conditions. Forcible bending acts on the bearing 10 and the valve shaft 9, which may cause damage to the bearing 10 and the valve shaft 9. Furthermore, since the valve shaft 9 slides within the bearing 10, both wear out.

いう問題点があつた。
As mentioned above, in the conventional water hammer pump drain valve 3, the valve shaft 9 is vertically fixed to the plate-shaped valve body 8, and the valve shaft 9 moves up and down within the bearing 10 to open and close the valve. However, there was a problem in that the bearing 10 and the valve shaft 9 were subjected to unreasonable bending, resulting in damage or wear to both.

めのものである。 FIG. 1 is a cross-sectional view of one embodiment of the water hammer pump drain valve of the present invention. In this figure, a drain valve mounting portion 2a of the valve chamber 2 is provided with a valve seat 14 having a drain port 14a formed in the center. A valve body movement distance adjusting section 15 is disposed above the valve seat 14 at a distance from the valve seat 14, and a plate-shaped elastic body 13 is further disposed at a distance from the valve body movement distance adjusting section 15. Elastic body 1
3 is a valve seat 1 made of something that can expand and contract, such as rubber.
4. The valve body movement distance adjusting part 15 and the elastic body 13 are integrally supported by the drain valve mounting part 2a by a general bolt-shaped valve body support part 16. Plate-shaped valve body 1
A valve stem 18 is integrally fixed to 2, the valve body 12 is located below the valve seat 14, and the valve stem 18 passes through the drain port 14a of the valve seat 14 and the valve body movement distance adjustment part 15, and It is supported by an elastic body 13 at the upper part. A gap is formed between the inner surface of the drain port 14a and the outer surface of the valve shaft 18. Further, a weight adjustment plate 17 for adjusting the weight of the valve body 12 is attached to the upper end of the valve shaft 18. Valve body movement distance adjustment section 1
5 is for adjusting the moving distance of the valve body 12 in the vertical direction.

損傷および摩耗は皆無である。 In this device, when the pressure inside the valve chamber 2 increases, water flows out through the drain port 14a as shown by arrow W. At this time, the pressure causes the valve body 12 to be pushed up, and the valve body 12 and the valve seat 14 come into contact with each other, thereby closing the drain port 14a and closing the drain valve. When the pressure inside the valve chamber 2 decreases, the weight of the valve body 12 causes the valve body 12 to
descends, opens the drain port 14a, and the drain valve becomes open. Since the valve body 12 is thus supported by the elastic body 13 via the valve shaft 18, the valve body 12 freely moves up and down in response to changes in water flow and water pressure to open and close the drain valve. That is, even if the valve stem 18 is slightly tilted when uneven water pressure is applied to the valve body 12 when opening and closing the valve, the elastic body 13 supports this at the outer circumference of the valve stem 18, so the valve body 12 will not be affected. It operates up and down, and when the valve is closed, the valve stem 18 easily returns to the vertical direction, and the drain valve is completely closed. Therefore, since bearings are not used as in the past, there is no damage or wear to the valve shaft and bearings.

As explained above, in the water hammer pump drain valve of the present invention, the valve body is supported by the elastic body at the outer circumference of the valve shaft via the valve shaft, and the valve body moves up and down due to pressure fluctuations in the water chamber to drain water. When opening and closing a valve, if uneven water pressure acts on the valve body, the elastic body allows the valve body to move up and down without any problem even if the valve stem is slightly tilted, and when the valve is closed, the valve stem easily moves vertically. After restoration, the drain valve is completely closed, which allows the valve bearing to be omitted, and there is no damage or wear to the valve stem and bearings as in the prior art.
