Problems solved by technology

[0004] Because the ignition device is used in special occasions, the ignition devices in the prior art are all used in industrial gas furnaces, and their performance cannot meet the requirements of the fire extinguishing training system.
For example, the flame length and rigidity produced by the ignition device in the prior art cannot meet the requirements; or the combustion air needs to be configured separately, resulting in a relatively complicated structure and increased volume, which cannot meet the requirements

Embodiment 1

[0028] like figure 1 As shown, the ignition device provided by the present invention for the firefighter fire training system includes a housing 3, a gas-air mixer 4, a base 5, an ignition rod 7 and a gas pipe 8; the ignition rod 7 runs through the base 5 and is fixed Inside the housing 3 , one end of the ignition rod 7 is connected to the base 5 through the ignition rod fixing seat 6 , and the other end of the ignition rod 7 is connected to the housing 3 through the ignition rod support block 2 . The ignition rod 7 and the ignition rod fixing seat 6 are compressed by a polytetrafluoroethylene pressure ring; the ignition rod fixing seat 6 and the base 5 are connected by threads; the base 5 and the shell 3 are connected by threads; the ignition rod supports The block 2 and the shell 3 are clamped and connected with the slot on the shell 3 through the elastic joint of the support block 2; the gas-air mixer 4 is arranged inside the shell 3, and the side wall of the gas-air mixer ...

Embodiment 2

[0035] like figure 2 As shown, the difference between this embodiment and Embodiment 1 is that an ion flame detection sensor 13 is installed in the flame detection interface 9 on the base 5 .

[0036] In this embodiment, the ion probe of the ion flame detection sensor 13 is arranged directly in front of the gas-air mixer 4, and it is ensured that the probe can be completely surrounded by the ignition flame generated by the ignition device.

Abstract

The invention belongs to the technical field of design of ignition equipment, and in particular, relates to an ignition device for a fireman fire extinguishment training system. The device comprises a shell, a base, an ignition rod, a gas-air mixer, an ignition rod fixed base, a gas pipe and an electric conducting needle; the ignition rod penetrates through the base to be fixed in the shell; the ignition rod and the base, and the ignition rod and the shell are in insulation contact; the gas-air mixer is arranged in the shell; one end of the gas-air mixer is a gas inlet hole, and is connected with the gas pipe penetrating through the base; the other end of the gas-air mixer is a gas-air mixed outlet; an electrode rod is arranged in the ignition rod; the shell is connected with the electric conducting needle; and the electrode rod and the electric conducting needle are arranged at intervals, and are fixed in front of the gas-air mixed outlet of the gas-air mixer. The ignition device can generate stable ignition flame with a certain length and rigidity under the condition of no special arrangement of air distribution facilities.

Description

technical field [0001] The invention belongs to the technical field of ignition equipment design, and in particular relates to an ignition device used in a firefighter fire extinguishing training system. Background technique [0002] As a key component of the firefighter fire training system, the ignition device mainly realizes the ignition function of the firefighter fire training system simulating the physical fire burner, and is applied to professional firefighters, part-time firefighters and enterprise employees to use fire extinguishers or high-pressure water guns for fire extinguishing technology training . [0003] The fire extinguishing training system requires that the ignition device is small in size and capable of producing a stable, reliable and controllable constant flame. In order to prevent the ignition device from being directly grilled by the burner flame, it is required that its constant flame flame has a certain length. In addition, since the fire exting...
