Claims

[Scope of utility model registration request]

A main body having an open upper part and an inlet and an inlet on the left and right sides, and an upward flow passage connected to the inlet in the center, a lid attached to the upper part of the main body, and a lid that penetrates the center of the lid and has this penetrating part. It consists of a valve stem that is screwed, and a diaphragm that is held between the main body and the lid at their outer peripheries. The valve is closed by pressing against a sheet at the end of the upward flow path, and the lowered diaphragm is made into an elastic deformation region, whereby the valve stem is raised to raise the diaphragm and open the valve. diaphragm seal valve.
