あった。This invention was published in Utility Application No. 52-164976 (Utility Application No. 54-8
No. 8930), as shown in FIG. C through hole d
In an exhaust valve in which a lid f having an exhaust hole e communicating with the valve body b is attached to the valve body b, several guide walls g are protruded from the inner wall b' of the valve body b to form a guide path h of the spherical valve a. The valve seat C is provided in a substantially inverted concave packing i whose peripheral edge i' is bulged downward with a roundness j, and the packing i is attached to the valve body b and the lid f. It was something that was interposed in between.
したがって、この排気弁においては貯水タンク内に水が

に排出される。Therefore, in this exhaust valve, when the water storage tank is filled with water, the air remaining in the water storage tank passes through the communication hole k at the bottom of the valve body b, pushes up the spherical valve a, and pushes up the valve body b. It passes through a guide wall protruding from the inner wall B, and is then discharged to the outside through the through hole d of the valve seat C and the exhaust hole e of the lid f.

is gradually floated and raised, and the spherical valve a rises along the guide path h and, as shown in FIG. 2, comes into close contact with the valve seat C and closes the through hole d, thereby stopping the water flow.
しかし乍ら、この排気弁には次の２つの欠点がある。However, this exhaust valve has the following two drawbacks.
即ち、球体弁ａは単に弁本体ｂの内底部に位置している
から、空気の押し上げによる球体弁ａの上昇がゆるやか

いをつけられて排気孔から外部に排出されるため、排気
弁の周囲を濡らしてしまう欠点があった。That is, since the spherical valve a is simply located at the inner bottom of the valve body b, the upward movement of the spherical valve a by air pushing up is gradual, and therefore the air in the valve body b is not discharged quickly. In addition, some water remaining in the communication hole k or inside the piping will follow the air during exhaust and be expelled from the exhaust hole with momentum, so the area around the exhaust valve may become wet. There was a drawback.

た排気弁を提供せんとするものである。The present invention aims to improve the above-mentioned defects, and its purpose is to remove the air remaining in the water storage tank by placing the spherical valve on a spring attached to the inner bottom of the valve body. The purpose of the present invention is to provide an exhaust valve that allows the air to be discharged more quickly and also that prevents some water remaining in the communication hole or piping from being exhausted from the exhaust hole following the air. be.

りである。That is, the present invention accommodates a spherical valve inside the valve body, and
Several valve guide protrusions are protruded from the inner wall, a through hole is bored in the center to form a valve seat, and an arcuate bulge is provided below the outer peripheral edge. A reverse concave packing is placed on the stepped part at the upper inner side of the valve body, and the threaded part of the lid body provided with the exhaust hole communicating with the through hole is screwed into the threaded part at the upper inner part of the valve body. In addition, in the exhaust valve in which the packing is attached to the upper part of the valve body, a spherical valve is placed on the upper part of a spring whose lower part is attached to the inner bottom of the valve body, and the spherical valve is attached to the inner bottom of the valve body. The present invention relates to an exhaust valve characterized in that the spherical valve is spaced apart from the upper part of the spring which is fully expanded when it contacts the seat, and the present invention will now be described by way of an example of implementation shown in the accompanying drawings. Then, it is as follows.

体１の下部に設けた連通孔である。That is, the present invention accommodates a spherical valve 2 made of ebonite or the like, which has a specific gravity lighter than water, inside a valve body 1, and has several valve guide protrusions 4 protruding from its inner wall 3. A through hole 5 is bored in the center to form a valve seat 6, and the outer peripheral edge 7 is
A substantially inverted concave packing 9 with an arcuate bulge 8 provided below is placed on a stepped portion 10 at the inner upper part of the valve body 1, and an exhaust hole 11 communicating with the through hole 5 is provided. In an exhaust valve in which the packing 9 is attached to the upper part of the valve body 1 by screwing the threaded part 13 of the lid body 12 to the threaded part 14 on the inner upper part of the valve body 1, the inner bottom part of the valve body 1 The spherical valve 2 is placed on the upper part 18 of the spring 17 which is fixedly attached by inserting the lower part 16 into the groove 19 provided in the groove 15, and when the spherical valve 2 contacts the valve seat 6, the spherical valve 2 in the figure relates to an exhaust valve characterized in that the valve 2 is spaced apart from the upper part 18 of the spring 17 that is fully expanded.
0 is a switching cock attached to the lower part of the valve body 1, and 21 is a communication hole provided at the lower part of the valve body 1.
次に作用を説明すると、貯水タンク内に水が充満すると

より外部に排出されるものである。Next, to explain the operation, when the water storage tank is filled with water, the air remaining in the water storage tank enters the inner bottom of the valve body 1 through the communication hole 21 of the valve body 1, resulting in the state shown in Fig. 1. As shown, the spherical valve 2 placed on the upper part 18 of the spring 17 and compressing the spring 17 is pushed up and comes into contact with the valve seat 6 above it; As a result, the gas passes through the gaps 4' of several valve guide protrusions 40 protruding from the inner wall 3 of the valve body 1, passes through the through hole 5 of the valve seat 6 above it, and enters the exhaust hole 11 of the lid body 12. , from which it is discharged to the outside.
この際、前記空気により球体弁２が押し上げられること
により、今まで該球体弁２の重みにより圧縮されていた
スプリング１７の圧縮力が急に解がれるため、該スプリ
ング１７が上方に伸張し、したがって、球体弁２は前記
スプリング１７の伸張力によって強く突き上げられて速
やかに上昇する。At this time, as the spherical valve 2 is pushed up by the air, the compressive force of the spring 17, which had been compressed by the weight of the spherical valve 2, is suddenly released, so the spring 17 expands upward, Therefore, the spherical valve 2 is strongly pushed up by the tension of the spring 17 and quickly rises.
よって、弁本体１内の空気を弁座６の透孔５を介して排
気孔１１より外部によく排出し、即ち、貯水タンク内に
残存する空気を外部に速やかに排出する。Therefore, the air in the valve body 1 is well discharged to the outside from the exhaust hole 11 through the through hole 5 of the valve seat 6, that is, the air remaining in the water storage tank is quickly discharged to the outside.
それとともに、連通孔２１や配管内に残っている多少の

がら外部に排出されないから、排気弁の周囲を濡らすこ
とはない。At the same time, even if some water remaining in the communication hole 21 or inside the piping follows the air during exhaust and is forced to be discharged to the outside through the exhaust hole 11, the spherical valve 2 The water immediately comes into contact with the upper valve seat 6 and closes the through hole 5, so that some of the water is stopped, and therefore the exhaust hole 11
Since the gas is not discharged to the outside, the area around the exhaust valve will not get wet.
上記のようにして弁本体１内から空気が排出されると球
体弁２は下降して弁座６から離れてスプリング１７の上

孔２１を通って弁本体１の内底部からその内部に入って
いくので、球体弁２を浮かせて押し上げ、該球体弁２は
前記水により弁座６によく密着して透孔５を確実に閉塞
して止水をよく行なうものである。When the air is discharged from the valve body 1 as described above, the spherical valve 2 is lowered, separated from the valve seat 6, and placed on the upper part 18 of the spring 17. Since it enters the inside of the valve body 1 from the inner bottom through the hole 21, the spherical valve 2 is floated and pushed up, and the spherical valve 2 is brought into close contact with the valve seat 6 by the water, and the through hole 5 is securely closed. It closes and effectively stops water.
しかして、球体弁２を押し上げる水圧が下がれば該球体
弁２は下降して前記弁座６がち離れて、再び第１図に示
すようにスプリング１７の上部部分１８上に載置するが
、また、水圧が上がれば球体弁２は上昇して止水するも
のである。When the water pressure pushing up the spherical valve 2 is lowered, the spherical valve 2 is lowered and the valve seat 6 is moved away and is again placed on the upper part 18 of the spring 17 as shown in FIG. When the water pressure increases, the spherical valve 2 rises and shuts off the water.

２の上昇による透孔５よりの空気の排出をよく行なうこ
とができる効果がある。In addition, in the present invention, when the spherical valve 2 contacts the valve seat 6, the spherical valve 2 is separated from the upper part 18 of the spring 17 which is expanded to the maximum. This has the effect that air can be well discharged from the holes 5.
