Claims

[Scope of utility model registration request]

(1) A fluid passage hole is provided in the valve casing that communicates with the fluid inlet and the fluid outlet, and a spindle that fits loosely into the fluid passage hole, seals the lower end liquid-tight, and can slide is inserted through the valve casing. A ball that performs a valve action is swingably mounted on the upper end of the spindle, and the lower end of the spindle is elastically held, and the ball is formed at the upper end opening of the fluid passage by the downward movement of the spindle. An automatic opening/closing valve characterized in that the valve is configured to be seated on a seat section.

(2) Automatic opening/closing according to claim 1 of the utility model registration claim, in which a socket having a fluid inlet that communicates with a fluid passage hole and accommodates a ball is liquid-tightly screwed onto the upper end of the valve casing. valve.

(3) A spring case that communicates with the fluid passage hole is screwed onto the lower end of the valve casing, and a pair of spring seats sandwiching a spring that elastically supports the lower end of the spindle are disposed within the spring case. The automatic opening/closing valve according to claim 1, which is a utility model, and has an adjustment screw in contact with one end of the spring seat.
