弁体から離間するとともに弁座を急激に閉じ、この弁座
の上流側にウォーター・ンマー現象を生じさせる。However, this device has the following drawbacks: When the valve body has a liquid passage opening, the liquid flowing from the liquid passage opening to the liquid discharge port may cause the liquid to flow upward to the lower peripheral edge of the valve body. Hydraulic pressure is acting to push up the valve body, so when the valve body is lowered, the valve body is pushed down by the secondary valve body, which descends with the lifting rod while blocking the liquid passage hole. As the valve body closes the valve seat of the liquid discharge port, the liquid pressure pushing up the lower edge of the valve body decreases. When the downward force of the liquid flowing into the valve becomes larger, the valve body instantly lowers faster than the lifting rod, separates from the sub-valve body, and rapidly closes the valve seat, causing water to flow upstream of the valve seat. cause the phenomenon of immersion.

記通液開口部41、弁座5および液吐出口4を経て受液
部A内に放出される。When the threaded rod 22 is further pushed up by the float link 10, the double nut 28 screwed in the middle of the threaded rod 22 engages with the guide engagement part 18, and the guide having this guide engagement part 18 also engages with the guide engagement part 18. The entire valve body 12 is pushed up via the plate 16, and the engaging edge 20 at its lower end is separated from the valve seat 5, and the one-flow liquid volume port 41 directly communicates with the liquid discharge port 4, and the liquid inlet body 6 into the casing 1 is discharged into the liquid receiving portion A through the liquid passage opening 41, the valve seat 5, and the liquid discharge port 4.
このように、弁本体12の上方の液体W2が通液小孔1
4を通して液抜きされた後に弁本体12が押上げられる
から。In this way, the liquid W2 above the valve body 12 flows through the small liquid passage hole 1.
This is because the valve body 12 is pushed up after the liquid is drained through the valve 4.
弁本体12を円滑に押上げることができる。The valve body 12 can be pushed up smoothly.
この場合、すなわち弁本体12がダブルナツト28によ

押上げを助勢する。In this case, when the valve body 12 is pushed up by the double nut 28, the pressure of the introduced liquid W is applied to the pressure receiving part 21 because the tapered pressure receiving part 21 is formed around the lower end of the valve main body 12. , acts to levitate the valve body 12 via this pressure receiving portion 21, and assists in pushing up the valve body 12.
したがって、弁本体12を一層容易に押上げ、液吐出口
4を迅速に開放することができる。Therefore, the valve body 12 can be pushed up more easily and the liquid discharge port 4 can be opened quickly.
つぎに、受液部Aに所定量供給されると、フロート30
が浮上されるとともに、フロートリンク10が反時計方
向に回動され、これに連結されたねじ杆22が下降され
る。Next, when a predetermined amount is supplied to the liquid receiving part A, the float 30
is floated, the float link 10 is rotated counterclockwise, and the screw rod 22 connected thereto is lowered.
この場合、ねじ杆22の上端部のスプリング受は板24

ら液室45の液体W2を排出しつつスプリング26を介
して弁本体12が下降連動される。In this case, the spring receiver at the upper end of the screw rod 22 is connected to the plate 24.
Since a spring 26 is interposed between the valve body 12 and the closing plate 13 of the valve body 12, the valve body 12 is lowered by the spring 26 while being pressed against the double nut 28, and the spring 26 moves the valve body 12 toward the valve seat. 5, the auxiliary valve body 23 is not compressed only by lowering the threaded rod 22, so the auxiliary valve body 23 descends while maintaining a distance from the small liquid passage hole 14, and as the threaded rod 22 lowers, the liquid flows / The valve body 12 is moved downward via the spring 26 while discharging the liquid W2 in the liquid chamber 45 from the No. L14.
そして、この弁本体12の係合縁20が弁座5に液密に
係合され通液開口部41が閉塞される。Then, the engaging edge 20 of the valve body 12 is liquid-tightly engaged with the valve seat 5, and the liquid passage opening 41 is closed.
つぎに、弁本体12が弁座5によって係止された状態で
ねじ杆22がさらに下降連動されると、スプリング26
が圧縮されなから副弁体23が下降され1通液小孔14
がこの副弁体23によって液密に保合閉塞される。Next, when the screw rod 22 is further moved downward while the valve body 12 is locked by the valve seat 5, the spring 26
is not compressed, the sub-valve body 23 is lowered and the small liquid passage hole 14 is lowered.
is fluid-tightly sealed and closed by this sub-valve body 23.

く一層たがってウォータハンマー現象が生じることなく
ケーシング1の液吐出口4が円滑に閉塞される。In this way, the valve body 12. The valve body 12 descends together with the screw rod 22 while being pressed against the double nut 28 by the spring 26, and after the valve body 12 comes into contact with the valve seat 5, the sub-valve body 23
2 descends together with the threaded rod 22 and closes the small liquid passage hole 14, so even if the upward hydraulic pressure applied to the pressure receiving part 21 of the valve body 12 decreases as the valve body 12 closes the valve seat 5,
There is no risk that the valve body 12 will descend faster than the threaded rod 22, and therefore the liquid discharge port 4 of the casing 1 is smoothly closed without causing a water hammer phenomenon.

の弁本体が液吐出口を閉塞してから副弁体がスプリング
に抗して下降して通液小孔を閉塞する。According to the present invention, a valve body for opening and closing the liquid discharge port is provided in the casing, and a small liquid passage hole communicating with the liquid discharge opening is bored in the valve body, and an elevator rod is connected to the liquid passage hole. The valve body is urged downward by a spring, and the small liquid passage hole of the valve body is separated from the secondary valve body, and the valve body is attached to the locking part of the lifting rod. Since the liquid discharge port of the casing is pressed, when the liquid discharge port of the casing is closed, the valve body is lowered with the small liquid passage hole open, and after this valve body closes the liquid discharge port, the sub-valve body resists the spring. and descends to close the small fluid passage hole.
したがって、弁本体のみが昇降杆よりも早く下降して弁
座を瞬時に閉じるおそれがなく、ウオタ・・ンマー現象
の発生を防止できる効果があり。Therefore, there is no risk that only the valve body will descend faster than the lifting rod and instantly close the valve seat, which has the effect of preventing the water phenomenon from occurring.
しかも弁本体の遮閉板と昇降杆の上端ねじ部に螺着した
ナツトで係止されたスプリング受は板との間に上記スプ
リングを介設したから、副弁体を通液小孔から開くスプ
リングの力をこのナツトによって調節することができ、
たとえば案内枠体内の液圧が高く副弁体を閉じる方向の
力が強い場合は、ナツトの調節によりスプリングの反撥
力を高めることにより、副弁体が容易に開くようにする
ことができる。Moreover, since the above spring is interposed between the closing plate of the valve body and the spring receiver, which is locked by a nut screwed into the upper end screw part of the lifting rod, the sub-valve body opens from the liquid passage small hole. The force of the spring can be adjusted with this nut.
For example, if the hydraulic pressure inside the guide frame is high and the force in the direction of closing the sub-valve body is strong, the sub-valve body can be opened easily by adjusting the nut to increase the repulsive force of the spring.
また、弁本体の上昇時にはスプリングの復帰力によって
副弁体と通液小孔とが確実に離間されたのち弁本体が押
上げられるので、弁本体の上方の液の液抜きが確実にな
され、弁本体は抵抗少なく迅速かつ円滑に上昇し、液吐
出口を容易に開放することができる効果がある。In addition, when the valve body is raised, the return force of the spring ensures that the sub-valve body and the small liquid passage hole are separated from each other, and then the valve body is pushed up, so that the liquid above the valve body is reliably drained. The valve body rises quickly and smoothly with little resistance, and the liquid discharge port can be easily opened.
したがってケーシングの液吐出口の開閉が常に円滑に行
ワレ、液体の過不足に敏感に対処することができる弁装
置を提供することができる。Therefore, it is possible to provide a valve device that can always smoothly open and close the liquid discharge port of the casing and can sensitively deal with cracks and excess or deficiency of liquid.

に昇降杆に嵌合したことを特徴とする弁装置。A casing comprising a valve seat formed at the peripheral edge of a liquid discharge port and a guide frame whose upper surface is closed through a liquid passage opening above the valve seat, and a guide frame of the casing. A valve body that is loosely fitted in the interior so as to be movable up and down, has an engaging edge at the lower end for opening and closing the valve seat, and has a small liquid passage hole at the upper end that communicates with the liquid discharge port, and liquid passage through the valve body. A sub-valve body is integrally provided with a locking part that is inserted into the small hole and the guide hole of the guide engagement part so as to be vertically movable and pushes up the guide and holding part of the valve body from below, and closes the small liquid passage hole from above. A lifting rod integrally formed with the valve body, a blocking plate having a small liquid passage hole in the valve body, and a spring receiver secured by a nut screwed onto the upper end threaded portion of the lifting rod are interposed between the plate and the above-mentioned valve body. The valve body is provided with a spring that urges the valve body to separate the small liquid passage hole from the auxiliary valve body and bring the guide engagement portion into contact with the locking portion. A valve device fitted to a lifting rod so as to be able to move up and down between the valve device.
