Abstract

PURPOSE: To assuredly cut off the gas flowing from an inlet port to an outlet port by means of a valve body which fits closely to the inlet port together with a seal member.
CONSTITUTION: An inlet port 2 opening upward is formed near the center of a main body 1, and the portion around the port 2 is recessed below the top face of the main body 1 to form a groove 3. An outlet port 4 having an aperture slightly smaller than the width of the groove 3 is formed downward from a proper position of the groove 3. An elastic round seal member 9 is arranged in the portion above the ports 2 and 4 and the groove 3, with the periphery covered airtight by a cap plate 10. The lower face of the seal member 9 communicates with the ports 2 and 4 to form an air chamber 11 of a proper volume. In emergency, a movable shaft 13 is freed from the attractive force of a permanent magnet 18, and a valve body 14 falls and pushes down the seal member 9 to plug up the inlet port 2 closely.
