Summary:A button-type valve for checking gas leakage is provided to improve convenience by enabling a user to perform operation for checking gas leakage easily. A button-type valve including a checking valve formed integrally in one side of a middle valve comprises a button(70) formed in an outer side of a checking valve, a piston part(80) formed inside the checking valve and moved up and down when pressing the button, a first blocking device(100) formed in one side of the piston part to open/close a supply path(90), a second blocking device(110) opening/closing a discharging path(120), and a gas pipe(132) installed inside a piston. A gas leakage at a gas exhaust port(41) is checked by providing gas into the gas pipe by pressing the button.
