The automatic on-off valve described in the former publication has a large negative pressure because the inside of the dust collector is in a negative pressure state while the dust collector is in operation, and when the operation is stopped, the inside is returned to normal atmospheric pressure. At atmospheric pressure, the on-off valve is lifted by the spring and opened, and the gas filled inside is released to the outside to prevent an explosion or the like.

In the latter publication, when the dust collector is in operation, the negative pressure inside the dust collector causes a valve element (a light one like a ping-pong ball) to block the exhaust hole. When you stop, the inside will return to normal atmospheric pressure, so
The mechanism is such that the explosive gas such as hydrogen gas that fills the inside is released to the outside when the valve body falls away from the exhaust hole.

However, in the automatic on-off valve described in the former publication, the horizontal member is installed inside the vent hole opening in the casing, and the horizontal member is projected. A lid that serves as an on-off valve is movably attached to the guide rod, and when the inside of the dust collector reaches atmospheric pressure, the spring pushes the lid to open the vent, so the lid can be used. If dust adheres to or is clogged with the guide rod or the like, there is a problem that it is difficult to open / close the vent hole by the lid, or the opening / closing operation becomes heavy, so that the vent hole cannot be accurately opened / closed.

Further, in the case of the device described in the latter publication, as shown in FIG. 4, a space is formed above the mounting position because the valve housing is mounted sideways. That is, there is an air pot at the top of the inside of the dust collector, and there is a problem that hydrogen gas accumulates in the air pot and is not completely released to the outside, so there is still a problem of explosion risk. At the same time, there is also a problem that dust accumulates in the lying valve housing, causing malfunction of the valve.

According to the means of claim 1 described in the above (1), the pressure inside the body of the device such as the dust collector becomes negative pressure during operation, and the spherical valve body is attracted to this negative pressure and is elastic. Since the body is sucked and moved toward the exhaust port to block it while stretching or bending the body, the device operates normally without causing air leakage. Also, when the operation of the device is stopped and the inside of the device returns to atmospheric pressure, the device body is pulled back by the elastic body and separates from the exhaust port, so the exhaust port opens and the gas filled inside the device is released to the outside. It ’s possible,
Since there are no members such as guide rods or springs inside the exhaust port, the opening and closing of the exhaust port does not hinder or become heavy due to dust adhesion or clogging. The operation can be performed smoothly and normally, and since no air pocket is generated at all, it is possible to discharge gas without leaving any residue.

According to the second aspect of the present invention described in (2) above, the exhaust port is opened at the upper end of the exhaust pipe erected at the uppermost part of the apparatus, and the exhaust port is formed obliquely. Therefore, even if the elastic body is cut and it becomes impossible to exert its elastic traction force (pullback force),
When the inside of the device returns to atmospheric pressure, the spherical valve element falls off the exhaust port along the slope and falls naturally, so even if you make a mistake, the exhaust port will not continue to be blocked and the gas filled inside the device will be released without hindrance. To enable that.

Since the automatic degassing valve according to the present invention has the structure as described above, the spherical valve body 4 is provided when the apparatus side is under normal pressure.
Is supported by the elastic bodies 5 and 5 in an open state separated from the exhaust port 2A of the exhaust pipe 2 shown in FIG. 1. However, when the device side has a negative pressure due to the start of the operation, it reaches the exhaust port 2A. The spherical valve body 4 is attracted by the suction action while stretching or bending the elastic bodies 5 and 5, and the exhaust port 2A is closed as shown in FIG. 2, so that the air is discharged from the exhaust port 2A. The device can be operated normally without causing leakage. Further, when the operation of the device is stopped and the inside of the device returns to normal pressure (atmospheric pressure), the elastic body pulls back the spherical valve body 4 to its original position by its elastic force. Can be discharged to the outside from the exhaust port 2A having an opening.

Since the exhaust port 2A is an inclined port, even if the elastic bodies 5, 5 are cut off, the exhaust port 2A can be kept closed even if the spherical valve body 4 is wrong when the operation of the apparatus is stopped. And the left and right elastic bodies 5 and 5 are exhaust ports 2
Since the spherical valve body 4 is supported at the same inclination angle as that of A, when the spherical valve body 4 closes the exhaust port 2A, the spherical valve body 4 suctions at a right angle to the inclined port of the exhaust port 2A. As described above, the exhaust port 2A can be surely closed, as described above. Further, the left and right elastic bodies 5, 5 supporting the spherical valve body 4 in an inclined state can be stretched or bent by the spherical valve body 4 or pulled back by the spherical valve body 4 under the same condition. Therefore, the opening and closing of the exhaust port 2A can be performed as it is along the inclination at a right angle and accurately.
