The valve seat 10 is formed with an air flow passage 13 that communicates from the outside to the side of the ring portion 112. The air flow passage 13 can introduce a high-pressure air to apply the thrust urging ring portion 112, so that the end portion 111 is separated. The valve hole 141, in turn, opens the glue outlet 21 that communicates with the end portion 111, so that the hot melt can flow out of the glue outlet 21 through the valve hole 141. A valve regulator 12 is disposed in the valve seat 10 for applying an elastic force to drive the ring portion 112, so that the end portion 111 closes the valve hole 141, thereby closing the glue outlet 21, so that the hot melt adhesive cannot pass through the valve hole 141. The glue outlet 21 flows out. In practice, the pressure regulator 12 is a compression spring. Moreover, the high pressure air located in the air flow passage 13 exerts a greater thrust than the pressure regulator 12 The spring force is applied, and therefore, the valve member 11 is pushed by the high-pressure air in the air flow passage 13 to open the valve hole 141. When no high-pressure air flows in the air flow passage 13, the valve member 11 is subjected to the elasticity applied by the pressure regulator 12. The valve hole 141 is closed by force.
