Claims

[Scope of utility model registration request]

A valve box, a diaphragm provided to divide the inside of the valve box into an upper chamber and a royal chamber, a spring built into the upper chamber to push down the diaphragm, and a spring provided on the peripheral wall of the valve box so as to communicate with the lower chamber. A pair of inflow passages and a discharge passage, and a pair of valve bodies whose lower ends are pivotally supported so that they can be rotated up and down in the lower chamber, and which are provided so that the valve plate comes into pressure contact with the valve seat of the inflow passage when rotated in the rising direction. , a spring installed in the lower chamber to apply a force in the closing direction to the pair of valve bodies, a switching rod installed in the lower chamber that moves up and down together with the diaphragm, and can be rotated from the outside. An automatic switching valve consisting of a switching rod and a switching cam with a step on the lower surface, which is provided to rotate the valve body in the direction of collapse.
