Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, the present invention is a kind of continuous ignition type flame spray head, including shower nozzle terminal pad, ignite disk and combustion gas
Nozzle, wherein the disk that ignites includes a toroidal cavity being arranged inside shower nozzle terminal pad, by some between the inwall of cavity
Support column is supported；A spout is provided with the top of shower nozzle terminal pad, the end set of spout has an injection cover plate, spray
Penetrate in cover plate and be provided with the flame spray chamber of tapered configuration, foregoing toroidal cavity wall opening in spout；The shower nozzle connection
The side wall of disk is provided with an annular exhaust cavity, is propped up between the inwall of exhaust cavity again by some support columns
Support, the support column are made of ceramic material；The annular array of exhaust cavity is provided with some admission lines；The gas injection
Mouth is coaxially disposed the lower position for the disk that correspondingly ignited in shower nozzle terminal pad, and the gas nozzle includes the nozzle of a divergent structure
Main body, the inwall of the spout are removably connected with a support ring, one are provided with the flared end of the nozzle body
Connection ring, the connection ring are supported in the top of support ring, and linear array is provided with some rings in the side wall of the gas nozzle
The raised rib of shape, it is arranged concentrically between raised rib, the flared end of nozzle body is provided with the spoiler of a network structure, described
