PREFERRED EMBODIMENT

[0020] As Figs. 1 to 3 Described, a kind of external hanging type large spray amount quantitative continuous valve, including fixed cover 10, valve rod 20, spring seat 30 and valve chamber 40, the spring seat 30 is located in valve chamber 40, the valve rod 20 one end is inserted into the spring seat 30 of valve chamber 40, the spring seat 30 is equipped with spring 31, spring 31 one end and the spring seat 30 abut the other end and the boss 21 of the valve rod 20 abut, the valve rod 20 other end is inserted into the fixed cover 10, the boss 21 end part of the valve rod 20 is set as hollow structure, through hole 22 is arranged in the side wall of the hollow structure, the outer periphery of the valve chamber 40 is equipped with a plurality of adding chambers 41, a plurality of adding chambers 41 and valve chamber 40 are interconnected.

[0021] In the specific implementation, the liquid inlet pipe 42 extends to the bottom of the pressure container, the contents in the pressure container and the high-pressure gas enter the lower part of the valve chamber 40 along the liquid inlet pipe 42, thereby introducing the liquid into the inside of the valve chamber 40 and the additive chamber 41, and pushing the valve rod 20 to move towards the valve chamber 40, at this time, the spring 31 is contracted, the through hole 22 of the valve rod 20 enters the valve chamber 40, and the lower groove 26 of the valve rod passes the lower sealing ring 24, and the liquid in the valve chamber 40 and the additive chamber 41 enters the inside of the valve rod 20 through the through hole 22 and is sprayed from the end.
