本考案は、弁装置、特にエアーベントに関する
ものであり、流体回路内に設けられた出力機構
(浮子の自重伝達機構)によつて開閉される弁体
の開弁力を軽減し、エアーベントの動作の感度を
向上させるものである。[Detailed description of the invention] The present invention relates to a valve device, particularly an air vent, and uses the opening force of a valve body that is opened and closed by an output mechanism (a float weight transmission mechanism) provided in a fluid circuit. This is to reduce the amount of noise and improve the sensitivity of air vent operation.
従来のエアーベントは、第1図に示すような構
成で、流体回路の開閉には、リフト弁が用いられ
ており、底部に流体回路との接続口を設け、上部
に空気排出口を設けた筒状の本体1内に、浮子3
が自由状態に収容され、この浮子とリンク機構に
よつて連動されたリフト弁4が前記空気排出口の
上流端に形成した弁座に対接する構成をとる。 A conventional air vent has the configuration shown in Figure 1, and a lift valve is used to open and close the fluid circuit, with a connection port to the fluid circuit at the bottom and an air outlet at the top. A float 3 is placed inside the cylindrical main body 1.
is accommodated in a free state, and the lift valve 4, which is interlocked with the float by a link mechanism, is configured to face a valve seat formed at the upstream end of the air outlet.
この従来のものでは、通常状態では、この本体
1内に貯留される水の浮力によつて浮子3が上方
に持ち上げられた状態にあり、他方、リフト弁4
には、バネ5の閉弁付勢力が作用することから、
このリフト弁4は閉弁状態に維持される。 In this conventional device, in a normal state, the float 3 is lifted upward by the buoyancy of water stored in the main body 1, and on the other hand, the lift valve 4
Since the valve closing biasing force of the spring 5 acts on ,
This lift valve 4 is maintained in a closed state.
流体回路内の空気量が増えて、上記本体1内の
空気量が増大すると、この本体1内の水位が降下
して浮子3に作用する浮力が低下し、この浮子3
の自重がリンク機構を介してリフト弁4に伝達さ
れ、このリフト弁4が開弁し、本体1内の空気は
外部に排出され、本体1内の水位が一定水位に復
帰すると浮子3に作用する浮力によつてリフト弁
4が閉弁せしめられる。 When the amount of air in the fluid circuit increases and the amount of air in the main body 1 increases, the water level in the main body 1 falls and the buoyant force acting on the float 3 decreases, causing the float 3 to drop.
The weight of the body is transmitted to the lift valve 4 via the link mechanism, the lift valve 4 opens, the air inside the body 1 is discharged to the outside, and when the water level inside the body 1 returns to a constant water level, it acts on the float 3. The lift valve 4 is closed by the buoyant force.
ところが、この従来のものでは、リフト弁4を
開弁させるに要する力が大きく、リンク機構部等
に僅かのゴミ咬みがあつたりすると円滑に動作し
ないという問題があつた。 However, in this conventional device, a large force is required to open the lift valve 4, and there is a problem that the lift valve 4 does not operate smoothly if a small amount of dirt gets stuck in the link mechanism or the like.
これは、流体回路内圧、すなわち、本体1の内
圧がそのままリフト弁4の閉弁方向に作用するか
らである。 This is because the fluid circuit internal pressure, that is, the internal pressure of the main body 1 directly acts on the lift valve 4 in the closing direction.
本考案は、このような〓流体回路に接続する中

めに、本体1内の圧力が弁体の開弁力として作用
するようにすることをその技術的課題とする。 In the present invention, a float 3 is provided in a free state in a hollow cylindrical body 1 connected to a fluid circuit, and the upstream side of an air outlet provided at the top of the body 1 is biased in a normally closed direction. The main body 1 is closed by the valve body
In an air vent in which the valve body is opened by the force of gravity acting on the float 3 when the water level inside the air vent falls, the sensitivity of the valve opening operation is improved and the operation is made smooth. In order to do this, the technical problem is to make the pressure within the main body 1 act as a valve opening force for the valve body.
上記技術的課題を解決するために講じた本考案
の技術的手段は、〓本体1の空気排出口を閉塞す

圧して流路を遮断する型式のピンチバルブとし、

部材15を浮子3の支持軸の上端に連設し、前記
支持軸を本体1内において昇降自在に支持し、弾
性管9の挟圧部の上流側を本体1内に開放させ
た〓ことである。 The technical means of the present invention taken to solve the above-mentioned technical problems are as follows: The valve body that closes the air outlet of the main body 1 is compressed by an elastic tube 9 made of rubber, plastic, etc. to block the flow path. As the model pinch valve,
One of the clamping means is a fixed clamping member 14 provided on the upper wall of the main body 1, and a movable clamping member 15 facing this is connected to the upper end of the support shaft of the float 3, so that the support shaft is The elastic tube 9 is supported in the main body 1 so as to be movable up and down, and the upstream side of the clamping portion of the elastic tube 9 is opened into the main body 1.
本考案の上記技術的手段は次の様に作用する。 The above technical means of the present invention operates as follows.
本体1内における空気貯留量が一定以下の場合
には、本体1内の水位が高く、常閉方向に作用さ
せた付勢力によつてピンチバルブは閉弁状態に維
持される。本体1内の貯留空気量が多くなると、
本体1内の水位が降下して浮子3に作用する重力
が増大し、この浮子3とともにその支持軸が降下
し、挟圧部材15が固定の挟圧部材14から離反
する方向に降下移動せしめられる。これにより、
弾性管9の挟圧部は開放し、ピンチバルブは開弁
し、空気排出口から貯留空気が排出せしめられ
る。ここで、ピンチバルブの閉弁状態では、その
挟圧部の上流側は本体1内に開放していることか
ら、弾性管9における挟圧部の上流側の管壁の内
外が同じ圧力条件下に置かれることとなり、流体
圧力により閉弁力が相殺された状態にある。 When the amount of air stored in the main body 1 is below a certain level, the water level in the main body 1 is high, and the pinch valve is maintained in the closed state by the biasing force acting in the normally closed direction. When the amount of air stored in the main body 1 increases,
As the water level in the main body 1 falls, the gravitational force acting on the float 3 increases, and the support shaft of the float 3 descends together with the float 3, causing the clamping member 15 to move downward in a direction away from the fixed clamping member 14. . This results in
The pinching portion of the elastic tube 9 is opened, the pinch valve is opened, and the stored air is discharged from the air discharge port. Here, in the closed state of the pinch valve, the upstream side of the pinching part is open into the main body 1, so the inside and outside of the tube wall on the upstream side of the pinching part in the elastic tube 9 are under the same pressure condition. The valve is placed in a state where the valve closing force is canceled out by the fluid pressure.
上記のように、ピンチバルブが開弁した後、本
体1内の水位が所定水位に復帰すると、浮子3の
作用力も低減して、常閉方向の付勢力によつてピ
ンチバルブが閉弁する。 As described above, when the water level in the main body 1 returns to the predetermined water level after the pinch valve is opened, the acting force of the float 3 is also reduced, and the pinch valve is closed by the biasing force in the normally closed direction.
以後、本体1内の貯留空気の量、すなわち、本
体1内の水位の変化に応じてピンチバルブが開閉
を繰り返し、本体1内の貯留空気量を常に一定に
保つこととなる。 Thereafter, the pinch valve repeats opening and closing according to changes in the amount of air stored in the main body 1, that is, the water level in the main body 1, and the amount of air stored in the main body 1 is always kept constant.
本考案は、上記構成であるから、次の特有の効
果を有する。 Since the present invention has the above configuration, it has the following unique effects.
弾性管9の挟圧部の上流側の管壁の内外が同じ
圧力条件下に置かれた状態で、ピンチバルブが閉
弁しているから、その分開弁力すなわち空気排出
口の開放力が軽減されることなり、既述従来のも
のに比べてエアーベントの感度が向上し、動作が
円滑なものとなる。 Since the pinch valve is closed while the inside and outside of the pipe wall on the upstream side of the pinching part of the elastic tube 9 are placed under the same pressure condition, the opening force of the valve, that is, the opening force of the air outlet is reduced accordingly. As a result, the sensitivity of the air vent is improved compared to the conventional ones mentioned above, and the operation becomes smooth.

べく取付けられる。 The air vent of the embodiment described above is installed, for example, at the highest water level of a hot water circuit of a water heater or the like, so that the inside of the main body 1 communicates with the inside of the hot water circuit through the inlet 22.
この使用状態の作用についてさらに詳述する

側は、透孔19を介して空室7側と連通している
ため、閉弁側に作用する力は挟圧部材15の挟圧
力と下流側の管壁25に作用する力のみとなる。 To explain in more detail the effect of this usage state, in the state shown in the figure, the chamber 7 is almost full of water and the float 3 is at the highest position. Therefore, the shaft portion 8
The gravity of the float 3 does not act on the valve, or this gravity is extremely small, and the pressing member 15 presses the middle of the elastic tube 9 by the biasing force of the spring 5, so that the valve is closed. In this valve-closed state, the upstream side of the clamping member 24 in the elastic tube 9 communicates with the cavity 7 side via the through hole 19, so the force acting on the valve-closing side is absorbed by the clamping member 15. Only the clamping force and the force acting on the downstream pipe wall 25 are used.

挟圧部材15がバネ5に抗して引き下げられる。 Next, when the air contained in the hot water circuit accumulates in the empty chamber 7 and the amount of stored air increases, the empty chamber 7
The water level inside will drop. When the water level reaches the working water level 2, a descending force corresponding to the difference between the weight of the float 3 and the buoyancy of the submerged part acts on the shaft part 8, and the shaft part, that is,
The pinching member 15 is pulled down against the spring 5.

is opened by the elastic return force of the tube wall of the elastic tube 9,
Air is removed. At the same time as this air removal, the water level in the empty chamber 7 rises and reaches the predetermined water level 6, the float 3 rises, the descending force of the shaft part 8 disappears, and the pinching part 15 is moved by the biasing force of the spring 5. 24 to block the flow path.
次に、第3図に示す実施例のものは、第4図の

向させたものである。 Next, as shown in FIG. 4, in the embodiment shown in FIG.
9, the through hole 19 is placed upward, and a fixed pressure surface 27 is provided on the periphery of the through hole,
A disk-shaped clamping member 15 is placed on the opposite side of the through hole 19.
また、空室7は、前記弾性管の中央の外周部か

9及び弾性管9内部に連通しており、その他の部
分は第1実施例と同様に構成されている。 Further, the empty chamber 7 is connected to the through hole 1 through a passage 28 extending from the central outer circumference of the elastic tube to above the through hole 19.
9 and the inside of the elastic tube 9, and other parts are constructed in the same manner as in the first embodiment.
この場合に於いても浮子3の最上昇位置では、

放端部とは遮断される。 Even in this case, at the highest position of the float 3,
The pinching member 15 presses one wall of the elastic tube 9 against the opposing wall, and the annular rib 26 is pinched between these two walls. Since the entire outer periphery of the annular rib is continuous with the inner surface of the elastic tube, the inside and outside of the annular rib 26 are blocked by the close contact between the annular rib and the tube wall. That is, the upstream side of the through hole 19 of the elastic tube 9 and the open end of the elastic tube 9 are cut off.
次いで、空室7内水位が降下して浮子3に所定
の重力が生じると、挟圧部材15が降下して弾性
管9の挟圧を解き、環状リブ26と管壁との間に
すき間が生じて空室7と弾性管9の開放端が連通
し、空気抜きされる。 Next, when the water level in the chamber 7 falls and a predetermined gravity is generated on the float 3, the clamping member 15 descends and releases the clamping pressure on the elastic tube 9, creating a gap between the annular rib 26 and the tube wall. As a result, the empty chamber 7 and the open end of the elastic tube 9 communicate with each other, and air is removed.
このように、この第2実施例も第1実施例と同
様にエアーベントとして機能する。 In this way, this second embodiment also functions as an air vent like the first embodiment.

にくらべて気密確保の為のつぶし代が多くなり、
閉弁性能が向上する。 In the second embodiment, the through hole 19 is provided in the tube wall in the area where the annular rib 26 is attached, so the area where the annular rib 26 is attached to the tube wall that the clamping member 15 is in contact with is inside and outside. The pressure is the same, and the force acting on the pipe wall in the valve closing direction is smaller than in the first embodiment. Therefore, the force required to open the valve is reduced, resulting in a valve that can be opened and closed with light force. In particular, in the case of the second embodiment, since the annular rib 26 is compressed between the pipe walls facing each other, airtightness can be ensured compared to a pinch valve that blocks the flow path by pressing the pipe walls against each other. The amount of money spent on crushing increases,
Improves valve closing performance.
尚、第2図に示す実施例の場合に於いて、空室

通させるようにしても第1実施例と同様に作用す
る。この場合、透孔19は不要である。 In the case of the embodiment shown in FIG. 2, even if the cavity 7 and the upstream side of the clamping portion 24 are communicated through the communication passage 29, the same effect as in the first embodiment is obtained. In this case, the through hole 19 is not necessary.
さらに、第2図に示す実施例では、固定側の挟
圧部材14の高さ調節を可能にしたから、他方の
挟圧部材15との挟圧力を簡単に微調整でき、作
動圧力を正確に設定できる。 Furthermore, in the embodiment shown in FIG. 2, since the height of the clamping member 14 on the fixed side can be adjusted, the clamping force with the other clamping member 15 can be easily finely adjusted, and the operating pressure can be adjusted accurately. Can be set.
