Description
Technical Field
[0001] The utility model relates to the technical field of fire extinguishing, in particular to an emergency triggering system with temperature control. Background Art
[0002] The heat-sensitive glass bulb is the core temperature-sensing component of a fire sprinkler head. The action temperatures of various colors are: orange 57°C, red 68°C, yellow 79°C, green 93°C, blue 141°C, and red is the most commonly used sprinkler head in our life. The fire sprinkler head is installed on the wall or ceiling and is connected to a water network pipeline filled with pressure, or individual sprinkler heads are installed along the pipeline to protect the area below them. When a fire occurs, the liquid inside the glass bulb of the sprinkler head starts to expand after being exposed to high temperature. When the set expansion temperature is exceeded, the liquid will squeeze and break the glass bulb. At this time, the water in the water pipe will flow out for fire extinguishing. It is a water spraying device that starts automatically within a predetermined temperature range under the action of heat, or is started by a control device according to a fire signal, and sprays water in a designed sprinkling shape and flow rate.
[0003] However, in the prior art, the heat-sensitive glass bulb is installed in a fire sprinkler head and is only used for a sprinkler system. It is difficult to integrate finished sprinkler heads, normally closed switch components, special encapsulation components, and starting power supply groups on the market into a precise temperature control electronic starting system.

A high-temperature heat-sensitive glass bulb is installed inside the normally closed switch component. A valve copper pin is installed on one side of the normally closed switch component close to the high-temperature heat-sensitive glass bulb. By setting the high-temperature heat-sensitive glass bulb, when the environment has a high temperature and exceeds the rated temperature of the heat-sensitive glass bulb, the glass bulb bursts and breaks, and the valve copper nail is pushed out and dropped by the movable rod of the normally closed switch component. The movable rod of the switch component is extended due to being released, and the internal metal contacts are connected to form a conducting state.
[0006] Preferably, the valve copper needle is arranged on the lower surface of the high-temperature thermosensitive glass ball, and the valve copper needle is in contact with the high-temperature thermosensitive glass ball. By setting the valve copper needle, it is convenient to cooperate with the high-temperature thermosensitive glass ball to control the closing of the spray valve, increasing the usability of the device.

One end is connected to the positive pole of the power supply group, and the other end is connected to the electronic start module. The remaining end of the electronic start module is connected to the negative pole of the power supply group to form a loop. At this time, the electronic start module is in a non-operating state, that is, it does not generate heat.

A bracket 8 is fixedly connected to the lower surface of the normally closed switch assembly 1. A spray valve 9 is installed on the lower surface of the bracket 8. A high-temperature thermal-sensitive glass bulb 10 is installed on the inner wall of the normally closed switch assembly 1. A valve copper pin 7 is installed on the side of the normally closed switch assembly 1 close to the high-temperature thermal-sensitive glass bulb 10. By setting the high-temperature thermal-sensitive glass bulb 10, when the environment has a high temperature and exceeds the rated temperature of the thermal-sensitive glass bulb, the glass bulb bursts and breaks, and the valve copper nail is ejected and dropped by the movable rod 3 of the normally closed switch assembly 1. The movable rod 3 of the switch assembly is extended due to being released, and the internal metal contacts are connected to form a conductive state.
[0022] Specifically, the valve copper pin 7 is arranged on the lower surface of the high-temperature thermal-sensitive glass bulb 10, and the valve copper pin 7 abuts against the high-temperature thermal-sensitive glass bulb 10. By setting the valve copper pin 7, it is convenient to cooperate with the high-temperature thermal-sensitive glass bulb 10 to control the closing of the spray valve 9, increasing the usability of the device.
[0023] Specifically, the encapsulation sleeve 4 is provided with internal threads, and the internal threads on the inner wall of the encapsulation sleeve 4 can be matched with DN15 or DN20. By setting the encapsulation sleeve 4, it is convenient to install the circuit, increasing the safety of the device and improving the usability of the device.
[0024] Specifically, after the encapsulation sleeve 4 is tightened, it forms an open-circuit power-off component, and the encapsulation sleeve 4 is arranged on the upper surface of the base 6.
[0025] Specifically, there are two contact pins 2, and the two contact pins 2 are arranged in mirror symmetry.
