Temperature-sensing and automatic on and off fire extinguishing device

Abstract

A temperature-sensing and automatic on and off extinguishing device includes: a valve body (1), a sealing auxiliary member (2), a sealing pad (3), a magnetic ring (4), a lower magnetic ring sleeve (5), an upper magnetic ring sleeve(6), a first temperature-sensing element (7), a bi-directional spacer (8), a large reset spring (9), a valve cover (17), a second temperature-sensing element (13), an actuating sleeve (12), a small reset spring (14), a connecting element (10), a sealing sleeve (18), a screw (11), a magnetic core rod (21) and a sealing cap (22). When a fire occurs, the first temperature-sensing element (7), affected by the rise of the surrounding environmental temperature, pushes the bi-directional spacer (8) to move upward.
