Be provided with the nitrogen start-stop device 6 that opens and closes nitrogen inlet and outlet in the described nitrogen chamber 73; This nitrogen start-stop device mainly comprises the upper and lower spool 63 that is movably arranged in the nitrogen chamber 73; In this spool is enclosed in by the valve stem casing 62 that is threaded in nitrogen seat 7 tops; Spool 63 outer walls are provided with and form sealing between " O " type circle 66 and the nitrogen chamber 73; Spool 63 tops are stretched out valve stem casing 62 and are exposed and be provided with adjusting screw 61, also are provided with valve core spring 64 between outside spool 63, takeing in shoulder and the nitrogen chamber 73; Also be provided with following " O " type circle 65 that is positioned at nitrogen outlet 72 the inners in the described nitrogen chamber 73, when spool 63 bottoms contact with this time " O " type circle, can close nitrogen outlet 72.
Described main body 1 is provided with rocker 4 with nitrogen seat 7 tops, and this rocker is shown in figure 13, and its left side is articulated and connected through straight pin 12 with main body 1, so rocker is around the relative subject freedom swing of straight pin; Rocker 4 bottom surfaces contact with the adjusting screw 61 of nitrogen start-stop device 6; Rocker 4 middle parts are provided with rectangle mounting hole 42; Movable pressure plate 3 is installed in this mounting hole; Movable pressure plate is shown in figure 14, and two boss 31 are extended in its bottom surface, and these two boss contact respectively on the push rod 87 of the push rod 87 of oxygen start-stop device 8 and liquid gas start-stop device 9; After a described hook 5 left ends pass rocker 4 and movable pressure plate 3 successively, connected fixingly by the plus screw on the rocker 41, hook right-hand member hook suspension place 51 supplies welding guns to shelve, and movable pressure plate 3 can freely swing in mounting hole 42.
This air throttle can open and close oxygen start-stop device 8, liquid gas start-stop device 9 and nitrogen start-stop device 6 simultaneously through rocker 4 and movable pressure plate 3; Its working procedure is following: during open mode such as Fig. 1 ~ and shown in Figure 6; Welding gun is taken down from the hook-shaped suspension of linking up with on 5 51, and the push rod 87 of oxygen start-stop device 8 does not receive movable pressure plate 3 compressings and the rising space occurs at this moment, under the effect of push rod spring 81; Push rod 87, elastic seal ring 84, capping 83 and seal ring 82 move upward simultaneously; This moment, seal ring broke away from the sealing inner to oxygen inlet 11, then oxygen inlet and oxygen outlet 10 connected state, the welding gun that is connected oxygen outlet gets final product ignition operation.And liquid gas start-stop device 9 is also identical with oxygen start-stop device 8 course of action, but also ignition operation of the welding gun that is connected liquid gas outlet 13.
Meanwhile; The adjusting screw 61 of nitrogen start-stop device 6 does not receive rocker 4 compressings and the rising space occurs; Under the effect of valve core spring 64, spool 63 moves upward with adjusting screw 61 simultaneously, and this moment, the spool bottom broke away from nitrogen outlet 72 inner following " O " type circles 65; Then nitrogen inlet 71 with nitrogen outlet 72 connected state, nitrogen gets into and is soldered pipeline and realizes protection.
When the welding job gap need be suspended; Can welding gun directly be suspended on hook-shaped suspension place 51 of hook 5; This moment is like Fig. 7 ~ shown in Figure 10; Because hook 5 pressurizeds drive rocker 4 and press down with movable pressure plate 3, this movable pressure plate press down together with the time press down the push rod 87 of oxygen start-stop device 8 and liquid gas start-stop device 9.The elastic force that the push rod 87 of oxygen start-stop device 8 overcomes push rod spring 81 moves downward; Will drive elastic seal ring 84, capping 83 and seal ring 82 successively moves downward; Seal ring sealing this moment oxygen inlet 11 the inners; Then oxygen inlet and oxygen outlet 10 are closed, and the welding gun that is connected oxygen outlet is promptly flame-out.In like manner liquefied gas inlet 15 is also closed with liquid gas outlet 13, and the welding gun that is connected the liquid gas outlet is also flame-out.
Meanwhile; Rocker 4 presses down the adjusting screw 61 that also presses down nitrogen start-stop device 6 simultaneously; This adjusting screw moves downward; The spring band movable valve plug 63 that will overcome valve core spring 64 moves downward, and this moment, the contact of spool bottom realized sealing on following " O " type circle 65 of nitrogen outlet 72 the inners, and then nitrogen inlet 71 is closed with nitrogen outlet.
Only need mention welding gun when welding again and can get into next work cycle.
The utility model only need just can open and close nitrogen start-stop device, oxygen start-stop device and liquid gas start-stop device through the hook of welding gun and hook simultaneously, so can reach the purpose of energy saving and environmental protection.
