Embodiment Construction
[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0013] see figure 1 , in an embodiment of the present invention, a low-expansion foam injection device includes a nozzle head 1, a dust cover 2, an upper body 3 and a lower body 5, and the nozzle head 1 is movably installed in the lower body 5, so the nozzle head 1 is placed on the lower body The inside of 5 can move up and down. The upper body 3 is movably installed on the top of the lower body 5. The upper body 3 and the lower body 5 are connected by threads...

The invention discloses a low-expansion foam injecting device which comprises a nozzle head, dustproof covers, an upper body and a lower body. The nozzle head is movably installed in the lower body. The upper body is movably installed at the top end of the lower body. The upper body and the lower body are in threaded connection. The dustproof covers are movably installed in the upper body through shaft pins. The dustproof cover plates are symmetrically installed in the upper body and are symmetric about the nozzle head. A reset spring acting on the corresponding shaft pin is arranged at one end of each dustproof cover plate. According to the low-expansion foam injecting device, the product performance is safe, reliable and stable, blockage is not likely to happen, the construction cost of an existing firefighting system of a hanger is reduced, installation is easy, the installation workload is reduced, and the low-expansion foam injecting device can be used on some specific occasions to improve the firefighting safety of the specific occasions.
Description
technical field [0001] The invention relates to the technical field of fire protection systems, in particular to a low-expansion foam spraying device. Background technique [0002] At present, the aircraft deck of an aircraft carrier is not protected by a fixed system, but is protected by fire trucks. In addition, domestic helicopter decks are protected with foam guns or foam guns. There are no fixed facilities on the existing large national defense equipment deck for protection, which causes more difficulties in the maintenance process of the equipment. Although, the foam gun is used for maintenance in the maintenance process, but the foam gun or foam gun has the disadvantages of large size and much higher cost than ordinary casting nozzles, so it cannot meet the needs of the existing situation. Therefore, existing equipment must be improved. Contents of the invention [0003] The object of the present invention is to provide a low-expansion foam spraying device to sol...
