In a preferred embodiment of the present invention, the trigger rope passes through the central holes of the spring and the piston nut in sequence to be connected with the trigger rope by a buckle.

In a preferred embodiment of the present invention, a safety pin for limiting the piston rod is provided on the valve.

In a preferred embodiment of the present invention, the valve includes a valve seat, a valve body, and a valve cap.

The utility model has the advantages that: the utility model provides a trigger device for fire extinguishing system, when kitchen top of a kitchen range and discharge flue when conflagration breaing out, the temperature sensor disconnection when the heat that flame produced reaches temperature sensor fusing temperature relaxs the trigger rope, spring release elastic pressure promotes the micro-gap switch that the piston rod gos forward the contact micro-gap switch seat, output fire signal gives extinguishing device, and can trigger the controller simultaneously and send fire signal to send the fire control center, overall structure is reasonable compact, response time is fast, safety and reliability, simultaneously have extensive market prospect in extinguishing device's application and popularization.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:

fig. 1 is a schematic view of the overall structure of a preferred embodiment of the triggering device for fire extinguishing system of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, an embodiment of the present invention includes:

a trigger device 100 for a fire extinguishing system comprises a valve seat 1, a valve body 2, a valve cap 3, a piston rod 4, a piston nut 5, a micro switch seat 6, a spiral spring 7, a trigger rope buckle 8 and a safety pin 9.

Set up complex screw thread respectively on disk seat 1 and the valve body 2 and be connected, preferably, disk seat 1 area screwed one end stretches into required fixing device's pilot hole, and valve body 2 passes through threaded connection fixedly from the opposite side of pilot hole with disk seat 1, sets up complex screw thread respectively on valve body 2 and the valve cap 3 and is connected.

The piston rod 4, the piston nut 5, the spiral spring 7 and the trigger rope buckle 8 are arranged in a cavity in the valve body 2, the micro switch seat 6 is arranged in a cavity in the valve cap 3, the safety pin 9 is inserted into the position of the piston rod 4 for limiting the valve body 2, the piston rod 4 is prevented from contacting with the micro switch of the micro switch seat 6 during assembly, the piston rod 4, the piston nut 5 and the spiral spring 7 are sequentially arranged from one end of the valve body 2 connected with the valve cap 3, one end of the trigger rope 11 sequentially penetrates through the spiral spring 7 and a central hole of the piston nut 5 to be fixedly connected with the trigger rope buckle 8, the trigger rope buckle 8 is arranged in the cavity at the end part of the piston rod 4, the cavity at the end part of the piston rod 4 is provided with a thread matched with the piston nut 5 for being connected with the piston nut 5, the size of the trigger rope buckle 8 is larger than that of, thereby fixing one end of the trigger cord 11 to the end of the piston rod 4.
