As shown in FIG. 9, in the faucet 80 of Patent Document 1, there is a possibility that gas G such as air stays in the curved portion 82c of the water discharge pipe 82 (liquid pipe). If the gas G stays in the curved portion 82c, there is a risk that an abnormal noise will be generated when water is discharged, or water will drip from the water discharge pipe 82 due to the expansion of the gas G when the water is stopped. In addition, there is a possibility that the gas G may become entangled in the jetting water, resulting in disturbance of the jetting water. SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide a gas venting structure, a gas venting member, and a water pump including the gas venting member that can suitably suppress the retention of gas in a curved portion of a liquid pipe. To provide a plug.

A gas venting structure for solving the above problems is a gas venting structure for venting gas accumulated in a liquid pipe having an inverted U-shaped curved portion, wherein an inlet is positioned at the curved portion and an outlet is located at the curved portion. A degassing guide that partitions a degassing channel located at the downstream end of the liquid pipe inside the liquid pipe, and a flow rate of the liquid that flows through the part other than the gas degassing channel is controlled by the degassing channel. and a flow rate adjusting portion that makes the flow rate smaller than the flow rate of the liquid, the flow rate adjusting portion includes a through hole as a discharge portion that discharges the liquid flowing through the portion other than the gas vent flow path, and the through hole The gist is that the size of the hole is smaller than the size of the inlet, or the flow control unit omits a discharge unit for discharging liquid flowing through a portion other than the gas vent flow path.

According to this configuration, the liquid flowing through the liquid pipe preferentially flows through the degassing channel by having the flow rate adjusting unit. In addition, since the inlet of the gas vent channel is located at the curved portion and the outlet of the gas vent channel is located at the downstream end of the liquid pipe, the gas accumulated in the curved portion is removed from the pressure of the liquid in the liquid pipe. It can be utilized to flow into the vent channel and out the downstream end of the liquid line. Therefore, it is possible to suitably suppress gas retention in the curved portion of the liquid pipe.

In addition, by providing the discharge portion in the flow rate adjusting portion, it is possible to prevent the liquid from stagnation in portions other than the gas vent flow path.

A degassing member for solving the above problems is a degassing member for degassing gas accumulated in a liquid pipe having an inverted U-shaped curved portion, wherein the inlet is positioned at the curved portion and the outlet is located at the curved portion. A degassing guide that partitions a degassing channel located at the downstream end of the liquid pipe inside the liquid pipe, and a flow rate of the liquid that flows through the part other than the gas degassing channel is controlled by the degassing channel. and a flow rate adjusting portion that makes the flow rate smaller than the flow rate of the liquid, the flow rate adjusting portion includes a through hole as a discharge portion that discharges the liquid flowing through the portion other than the gas vent flow path, and the through hole The gist is that the size of the hole is smaller than the size of the inlet, or the flow control unit omits a discharge unit for discharging liquid flowing through a portion other than the gas vent flow path.

According to this configuration, the liquid flowing through the liquid pipe preferentially flows through the degassing channel by having the flow rate adjusting section. In addition, since the inlet of the gas vent channel is located at the curved portion and the outlet of the gas vent channel is located at the downstream end of the liquid pipe, the gas accumulated in the curved portion is removed from the pressure of the liquid in the liquid pipe. It can be utilized to flow into the vent channel and out the downstream end of the liquid line. Therefore, it is possible to suitably suppress gas retention in the curved portion of the liquid pipe.

In addition, by providing the discharge portion in the flow rate adjusting portion, it is possible to prevent the liquid from stagnation in portions other than the gas vent flow path.

It is preferable that the faucet includes the degassing member and a discharge pipe as the liquid pipe. According to this configuration, the faucet can function as the degassing member.

According to the degassing structure, the degassing member, and the faucet provided with the degassing member of the present invention, it is possible to suitably suppress retention of gas in the curved portion of the liquid pipe.

As shown in FIG. 5(b), when the water W is allowed to flow further, the water W in the discharge pipe 20 climbs over the curved portion 20c and flows into the downstream end 20b side of the discharge pipe 20. As shown in FIG. The water discharge pipe 20 and the water discharge port member 30 are watertight, and the water discharge pipe 20 is watertight between the water discharge port member 30, the flange portion 52 of the degassing guide 50, and the pressing member 40. Water W begins to accumulate on the outer peripheral side of the tubular portion 51 of the gas vent guide 50 on the side of the downstream end 20b. A portion of the water W on the downstream end 20 b side of the water discharge pipe 20 is discharged from the through hole provided in the tubular portion 51 of the degassing guide 50 . By increasing the flow rate of water W flowing in from the upstream end 20a of the water discharge pipe 20 more than the flow rate of water W discharged from the through hole of the gas vent guide 50, the amount of water W in the water discharge pipe 20 changes over time. increase in As the amount of water W in the discharge pipe 20 increases, the gas G in the discharge pipe 20 is pushed out by the water pressure in the discharge pipe 20, and flows into the gas release guide 50 from the upstream end 50a of the gas release guide 50. It flows in and is discharged from the downstream end 20 b of the discharge pipe 20 .

As the amount of water W in the discharge pipe 20 increases further, the water level in the discharge pipe 20 reaches the upstream end 50 a of the gas vent guide 50 .
As shown in FIG. 5(c), when the amount of water W further increases, the gas G in the water discharge pipe 20 is drawn into the flow of water W preferentially flowing in the gas vent guide 50, 50 and is completely discharged from the downstream end 20b of the discharge pipe 20. As shown in FIG. As a result, the inside of the discharge pipe 20 is filled with the water W. As shown in FIG.

As described above, the gas G in the discharge pipe 20 is discharged from the downstream end 20b of the discharge pipe 20. As shown in FIG. Therefore, the spout member 30, the pressing member 40, and the degassing guide 50 constitute a degassing structure and degassing member. In addition, the inside of the tubular portion 51 of the gas vent guide 50 functions as a gas vent channel, and the portion other than the gas vent channel between the inner surface of the water discharge pipe 20 and the outer surface of the tubular portion 51 of the gas vent guide 50 becomes.
