ヒフ１゜まう。Water supply valves (hydrant faucets) used in water supply equipment include:
Usually, a claw valve type is used, which opens and closes by moving a top-shaped gasket upward. This type of water supply valve exhibits good opening and closing performance when the tap water is not contaminated with fine particles such as sand or mud. If the stand is contaminated with fine particles, please be careful not to get sand or other foreign matter between the seals.

貫通孔１４１内に流入する。As shown in FIG. 1, the central through hole 1 of the ball-shaped valve body 14
When the di of 41 and the valve body 11 are matched,
Tap water flows from the inlet 12a to the valve chamber 12 as shown by the arrow.
．． It enters the central through hole 141 and flows from the outlet], 2b to the faucet 1u11 member 11a. At this time, some of the tap water flows through the large-diameter opening 14 that is connected to the central through-hole 141.
2 side, reverses within the space LZc formed between the top of the ball-shaped valve body 14 and the bottom of the valve chamber 12, and flows again to the center through hole 141 side. By this flow toward the large-diameter opening 142, fine particles such as sand that remain in the paper section wall gap 12c of the valve chamber 2 are flowed out. In addition, the large diameter Sekiguchi 142
As shown in FIG.
d, and flows into the central through hole 141 again through the small diameter opening 143 in the upper part.
この流れにより、ボール状弁体１４の外周部への倣ａ粒
子の沈層が防止される。This flow prevents the imitation a particles from settling on the outer periphery of the ball-shaped valve body 14.

１４の外周部との間に微細粒子が侵入することがない。In this way, according to this embodiment, a large flow is always generated in the space 12cG between the lowest part of the ball-shaped valve body 4 and the bottom of the valve chamber 12, where the most minute particles tend to settle.
It is possible to prevent fine particles from settling into the space 12c. In addition, the gap 12d at the outer circumferential portion of the ball-shaped valve body 14 causes a long flow, thereby preventing fine particles from depositing. As a result, the hole-shaped valve body 1
4 is rotated and comes into sliding contact with the valves pJ413a and 13b, even if the square f! Fine particles do not enter between 413a, 13b and the outer periphery of the ball-shaped square body 14.

圧力損失がきわめて少ない。According to this embodiment, even if water containing fine particles such as sand flows, it will not cause the #111a to precipitate as it flows through the tank, and the fine particles will not settle between the valve body and the valve seat. It is possible to always ensure good sealing performance without digging in. Also, since the water passage is straight,
Extremely low pressure loss.
