The specific embodiment
Below will combine Figure of description and specific embodiment that the utility model is explained further details.
As depicted in figs. 1 and 2, the high effective foaming rifle of the utility model comprises gun barrel 6 and cylinder 2, and an end of gun barrel 6 offers nozzle 10, and the other end of gun barrel 6 is connected with air inlet pipe 5 with cylinder 2.Be arranged with a valve rod 7 in the inner chamber of gun barrel 6, an end of this valve rod 7 is connected with cylinder 2 interior piston rods 3, and is provided with compression spring 1 on piston on the piston rod 3 31 and the cylinder 2 between the madial wall away from valve rod 7 one ends; The other end of valve rod 7 is provided with and is used for the elasticity valve head assembly 9 that is sealed and matched with nozzle 10.In the present embodiment, this elasticity valve head assembly 9 comprises iron core 11 and elastic component 12, and iron core 11 is fixed on the end of valve rod 7, and elastic component 12 is used for and nozzle 10 contact matching.In this instance, elastic component 12 can adopt flexible glue spare.Elastic component 12 can produce certain distortion under pressure, with position and the shape that adapts to nozzle 10, even if occur under the situation of processing or rigging error; Also can carry out adaptive adjustment; With with nozzle 10 better fit, improve the sealing effectiveness of foam gun when closing, and then improve foaming effect.
In the present embodiment,, on piston rod 3, be provided with first and support centring ring 4, and the position near elasticity valve head assembly 9 is provided with the second support centring ring 8 on valve rod 7 in order further to guarantee the assembly precision of valve rod 7.During assembling; Can support centring ring 4 with first be sheathed on the piston rod 3, second support centring ring 8 and be sheathed on the valve rod 7; Then valve rod 7 is sheathed in the gun barrel 6; To guarantee assembly precision, make the elasticity valve head assembly 9 of valve rod 7 can be better and the matching of nozzle 10, and then the raising sealing effectiveness.The outer ring of the second support centring ring 8 is fixed on the inwall of gun barrel 6; Inner ring is used to locate valve rod 7; Be used for circulated gases between outer ring and the inner ring, this second support centring ring 8 is used to guarantee that valve rod 7 ability accurate localization at the center of gun barrel 6, make the central lines of valve rod 7 and nozzle 10.First supports the structure and the second support centring ring, the 8 structure basically identicals of centring ring 4.
In the present embodiment, valve rod 7 is connected with cylinder 2 interior piston rods 3 through screw thread, and one can shorten the entire length of valve rod 7, to reduce the difficulty on the machining accuracy; Two, can also further reduce the difficulty of valve rod 7 when assembling, help guaranteeing the central lines of cylinder 2, piston rod 3 and valve rod 7.
In the present embodiment, air inlet pipe 5 comprises a body and two pipe boxes, and two pipe boxes are used for connecting gun barrel 6 respectively and are connected with cylinder 2 and employing thread fiting mode.
