Abstract

PURPOSE: To enable precise flow velocity control by providing in same flow passage a flow rate control part having a needle fitted into a through hole sliding-free in and out of said hole and a reverse flow check part having a cone shaped diaphragm the circumference of which is abutted to the flow passage.
CONSTITUTION: A pushnut 16 is formed of a stainless steel sheet with springiness having six legs extending gradually in umbrella like manner and is installed abutting a stepped part a2 of a flow passage 14, a through hole being made at the center of said pushnut 16 and a cone shaped synthetic rubber diaphragm 22 is installed integrally thereto, the lower circumference of said diaphragm being abutted to the lower inner surface of the flow passage 14, and a needle 24 being fitted in said through hole 20 free to slide up and down. When the air flow moves from the passage 14 to the direction of a passage 32 the cone of the diaphragm 22 opens to close the passage 14 and the fluid flows through a gap between the needle 24 and the through hole 20 as a controlled flow. In case of a reverse flow the diaphragm 22 closes to allow free flow.
