技術によるものであった。Conventionally known air extraction silencing devices such as wound supply devices (Special Publication Publication No. 53-2
One of the deficiencies in the Japanese Patent Publication No. 3527 is that the air exhaust silencing effect is not sufficient. That is, FIG. 1 shows the conventionally known Japanese Patent Publication No. 53-2352, which is the object of the present invention.
In the figure, A is the main body of the air exhaust silencing pipe, B is the air chamber, C is the horizontal inflow pipe, and D is the horizontal discharge pipe, which is described in Publication No. 7. The technology to sufficiently remove the air bubbles that occur when overflowing, and the technology to sufficiently silence noise such as the combustion sound of the boiler and the vibration sound of the circulation pump, can only be achieved by increasing the length L of the main body of the muffling pipe A. (Usually manufactured to a length of 60 to 900 pieces. Of course, the larger the length L, the greater the effect). Therefore, if you want to completely remove air bubbles and completely prevent noise, the technique is to install longer ones and more of them.

高性能の抜気消音装置を得ることが出来たものである。However, after conducting various experiments, we found that the conventionally known ones were
Even if the length L was made larger, the effect was not sufficient, and there was a need to fundamentally improve this point. The present invention is a fundamental improvement on this,
Even if the length L is shortened more than the conventional length, not only can a satisfactory exhaust noise silencing effect be expected, but also the noise has been actually measured with a measuring device, and it has a high performance that far exceeds that of the conventional one. We were able to obtain an air exhaust silencer.

Therefore, the partition wall 5 is not installed at the center position in the length direction of the air exhaust muffling/guipoo, but is installed close to the inlet port 3 side.

本発明は上述の構成であり、流入口３より流入した湯は
、それが湯であるため、多量の気泡を含んで小なる容積
の流入室６内に流入する。The present invention has the above-described configuration, and since the hot water that flows in from the inlet 3 is hot water, it flows into the inflow chamber 6 having a small volume containing a large amount of bubbles.

図面代用写真に示したように顕著な効果を発揮する。In addition, since it is hot water, it flows into the inflow chamber 6 with the noise of the boiler and pump, but since there is a partition wall 5 at the position where the inflow port 3 abuts, it collides with this and changes direction. and because the flow velocity decreases all at once from the inlet 3 with a small inner diameter to the inlet chamber 6 with a larger inner diameter, the noise is considerably suppressed and the bubbles are separated from the hot water. It gathers at the upper wall 14 and reaches the discharge chamber 7 through the guide hole 15. The hot water that has flowed into the inflow chamber 6 passes through the lotus passage 8 with a small cross section again, and flows into the discharge chamber 7, which has a larger internal diameter and a larger volume, and has an active air removal effect. In the end, according to the present invention, in one noise-reducing pipe main body 1,
The air exhaust silencing effect is carried out twice in stages. In the present invention, an inlet 3 is formed in the vertical wall 2 on the inflow side of a horizontal cylindrical exhaust noise muffling pipe main body 1, and a horizontal inflow pipe 4 is connected to this. is attached to the partition wall 5 to divide it into an inflow chamber 6 and a discharge chamber 7, and the partition wall 5 is closed with a lotus passage port 8 that allows the two chambers 6 and 7 to pass through each other.
The discharge-side vertical wall 101 of the air exhaust silencer pipe main body 1 includes:
A discharge port 9 is formed at the same height as the inlet port 3 and a horizontal discharge pipe 11 is connected thereto, and a vent chamber 12 is formed on the upper surface of the discharge chamber 7.
Since the vertical partition wall 5 is installed close to the inlet 3 side, the water flows twice into the inflow chamber 6 from the inflow port 3 and when it flows into the discharge chamber 7 from the lotus port 8. As a result, a sound silencing effect can be expected, and the silencing effect is particularly remarkable as shown in the photograph substituted for the drawing in Figure 6.

又、前記したように、隔壁５は、その中央位置に設ける
ものではなく、流入口３側に片寄らせて取付け、もって

階的に抜気消音作用を発揮させ、一層効果を顕著ならし
めるものである。Furthermore, as mentioned above, the partition wall 5 is not installed at the center, but is installed offset to the inlet port 3 side, thereby making the inflow chamber 6 smaller than the discharge chamber 7. This makes the effect even more pronounced by exerting an air exhaust silencing effect.
