Title:
TEMPERATURE-SENSING AND AUTOMATIC ON/OFF FIRE EXTINGUISHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/054305
Kind Code:
A1
Abstract:
Disclosed is a temperature-sensing and automatic on/off fire extinguishing device, consisting of a valve body (1), a sealing auxiliary member (2), a sealing pad (3), a magnetic ring (4), a lower sleeve of the magnetic ring (5), an upper sleeve of the magnetic ring (6), a temperature-sensing element 1 (7), a bi-directional spacer (8), a large reset spring (9), a valve cover (17), a temperature-sensing element 2 (13), an actuating sleeve (12), a small reset spring (14), a connecting element (10), a sealing sleeve (18), a screw (11), a magnetic core (19), a magnetic core sleeve (20), a magnetic core rod (21) and a sealing cap (22); when a fire occurs, the temperature-sensing element 1 (7), affected by the rise of the surrounding environmental temperature, pushes the bi-directional spacer (8) to move upward, the upward movement of the bi-directional spacer (8) compresses the large reset spring (9), as the ambient temperature continues to rise, the temperature-sensing element 2 (13) elongates and compresses the small reset spring (14) to push the connecting element (10) to move upward, the upward movement of the connecting element (10) drives the upper sleeve of the magnetic ring (6), the lower sleeve of the magnetic ring (5), and the magnetic ring (4) to move upward, the magnetic ring (4) draws the magnetic core (19) to move upward, the upward movement of the magnetic core (19) moves the magnetic core rod (21) and the sealing cap (22) up, the device starts the water spray to extinguish the fire. When the fire is extinguished, the ambient temperature is reduced, all of the components are in reset state, and the device is off to stop spraying water.
