ツプリング。 A valve core having an insect valve at one end and a head at the other end, a protective cylinder surrounding the valve core and having a valve seat that is constantly in contact with the insect valve with spring pressure, and having a stepped portion around it; A cylindrical male joint with both ends open, a large diameter chamber in which the male joint is accommodated, a cylindrical female joint with both ends open and having a small diameter chamber communicating with the large diameter chamber; A cylindrical part provided in a small-diameter chamber and facing the peripheral edge of one end of the male joint via packing, a first spring that biases this cylindrical part toward the male joint, and a first spring that slides inside the cylindrical part. a bottomed cylinder having a small hole that communicates with the large diameter chamber and is biased toward the head side of the male joint by a second spring having a spring pressure weaker than the spring pressure of the first spring; a push pin having a shape of a shape, a plurality of balls provided around the periphery of the female joint and engaging with the stepped portion when the large diameter chamber of the male joint is accommodated, and supporting the balls in a manner that is slidable with respect to the female joint. It becomes a cylindrical cover,
When both joints are connected, the male joint contacts the cylindrical portion against the spring pressure of the first spring, the head of the valve core contacts the push pin against the spring pressure of the second spring, and the insect A charge coupling that separates the valve from the valve seat.
