Description of drawings
Fig. 1 is the structural representation of fluidisation blast cap in the prior art.
Fig. 2 is used for the structural representation of the fluidisation blast cap of leakproof slag for the present invention.
Fig. 3 is used for the fluidisation blast cap holddown groove of leakproof slag and the sketch map that is connected of blast pipe for the present invention.
The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
Like Fig. 2, shown in Figure 3, the fluidisation blast cap that the present invention is used for the leakproof slag comprises a blast pipe 1 and a cap head 2.Blast pipe 1 wears and is fixed in the cap head 2, in blast pipe 1, is connected with one and opens and closes parts.Said keying parts are mainly used in to be opened or shutoff blast pipe 1.
Preferably, said keying parts comprise an elastomeric element, an annular tray 3 and a shutoff piston 5.Wherein, annular tray 3 is fixed on the madial wall of blast pipe 1.Said elastomeric element is preferably a spring 6, the one of which end is fixed in the blast pipe 1 (for example is fixed on the top in the blast pipe 1), and the top of the other end and shutoff piston 5 is affixed.At this moment, fitting in the upper surface of the bottom of shutoff piston 5 and annular tray 3, or has a space between the upper surface of the bottom of shutoff piston 5 and annular tray 3.
Further, said keying parts also comprise a holddown groove 4.As shown in Figure 3, holddown groove 4 is rigidly attached on blast pipe 1 madial wall through fixed strip 41, for example can adopt the next fastening holddown grooves 4 of mode such as welding.At this moment, the end with spring 6 is fixed in the holddown groove 4 again, and the other end of spring 6 is fixed in the top of shutoff piston 5.Like this, shutoff piston 5 just can be connected with holddown groove 4 through spring 6, produces certain pretightning force by spring 6, can reduce because the frequent movement of the shutoff piston 5 that the stream pressure fluctuation produces.The top of shutoff piston 5 is preferably a cylinder, and the bottom of shutoff piston 5 is preferably a round tray, need guarantee the internal diameter of said cylindrical diameter less than holddown groove 4 simultaneously, and the diameter of said round tray is greater than the internal diameter of annular tray 3.Easy on and off is movable neatly in holddown groove 4 can to realize shutoff piston 5 like this.
