Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1, cylinder 1 bottom is installed in cylinder fitting seat 15 tops through four bolt, and these four bolts are circumferentially evenly arranged along cylinder fitting seat 15.Be connected through four bolt between cylinder fitting seat 15 bottoms and outer can upper valve body 12 tops, and both attachment portions are positioned at outside the valve body of this filling liquid combination valve, these four bolts are circumferentially evenly arranged along cylinder fitting seat 15.The bottom of the cylinder column 17 of cylinder 1 is fixedly connected with valve rod connecting head 16 screw threads, and valve rod connecting head 16 connects with valve rod 3 top card loads.
As shown in Figure 1, the circular crossette at outer can upper valve body 12 tops cooperates butt joint with the circular port of cylinder fitting seat 15 lower ends, plays the radial location effect.The circular crossette center at the top of outer can upper valve body 12 has circular port, is set with valve stem packing ring installation sleeve 14 in this circular port.Be connected through four bolt between the circular crossette of outer can upper valve body 12 and the valve stem packing ring installation sleeve 14, these four bolts are circumferentially evenly arranged along valve stem packing ring installation sleeve 14.Valve stem packing ring installation sleeve 14 is cylindrical shapes that the top is provided with boss, and the boss at valve stem packing ring installation sleeve 14 tops is stuck in the annular groove in the circular crossette top of outer can upper valve body 12.Valve rod 3 passes the center hole of valve stem packing ring 13 installation sleeves 14, is provided with twice valve stem packing ring 13 up and down between valve stem packing ring installation sleeve 14 and the valve rod 3, and valve stem packing ring 13 is rubber material sealing O type circle.
As shown in Figure 1, it is outer and be positioned at the bottom of outer can upper valve body 12 that can Returnning spring 2 is enclosed within valve rod 3, and can Returnning spring 2 top card are outside in the groove bottom the can upper valve body 12 circular crossettes.Be provided with spring washer 19 between the groove of can Returnning spring 2 and outer can upper valve body 12.Valve rod 3 bottoms are cylinder shape groove, and groove top is provided with the Kong Lu that is interlinked to the outside with bar, and can Returnning spring 2 bottoms are stuck on the crossette of valve rod 3 bottoms.Be connected through bolt between the valve body 6 under the boss of valve rod 3 bottoms and the interior negative suction, valve body 6 is the U-shaped cylindrical shell under the interior negative suction.The boss of valve rod 3 bottoms is the upper valve body of interior negative suction valve simultaneously.
Be provided with the negative valve Returnning spring 5 of inhaling in the low groove of valve rod 3 bottoms, negative valve Returnning spring 5 bottoms of inhaling are provided with the interior negative spool 7 of inhaling.In negative spool 7 tops of inhaling in being stuck in the negative cylindrical shell of inhaling valve body 6 down, the negative suction down outside valve body 6 bottoms in the bottom of interior negative suction spool 7 reaches.Be with valve head 9 outside the bottom of interior negative suction spool 7 and pass through screw thread between the two and be fixedly connected; Bear in forming between the valve body 6 under interior negative suction spool 7 and the interior negative suction and inhale chamber 8; The interior negative spool 7 of inhaling is designed with the Kong Lu that communicates with interior negative suction chamber 8, and the hole road the other end is connected to outside the valve head.Embedded seal ring 10 between the valve body 6 under interior negative suction spool 7 and the interior negative suction.
As shown in Figure 1, outer can upper valve body 12 is a cylindrical shape, and a side at outer can upper valve body 12 middle parts is provided with the material feeding mouth A with its internal communication, material feeding mouth A be cylindrical shape and and outer can upper valve body 12 between the welding.Be provided with boss outside the middle and lower part of outer can upper valve body 12.Outer can upper valve body 12 bottoms are externally connected with under the outer can valve body 4 and are fixedly connected through screw thread between the two; Be provided with seal washer 11 between valve body 4 tops under the boss of outer can upper valve body 12 middle and lower parts and the outer can; Seal washer 11 is for gathering the tetrafluoro packing ring; Valve body 4 is the U-shaped cylindrical shell under the outer can, and valve body 4 bottoms are provided with the discharge port B that cooperates with valve head 9 bottom shapes under the outer can.
As shown in Figure 1; Valve body 6, interior negative suction spool 7 have constituted an inner little interior negative suction valve under valve rod 3, negative suction valve Returnning spring 5, the interior negative suction, and valve body 4, outer can upper valve body 12, valve rod 3, can Returnning spring 2 and valve head 9 have constituted a big outer filling valve under the outer can.Between interior negative suction valve and the outer filling valve is to be sleeved on together inside and outside 18, two valves of outer can valve pocket.
As depicted in figs. 1 and 2, when the cylinder column 17 of cylinder 1 moves upward, to open thereby drive outer filling valve, interior negative suction valve body is upwards mentioned, and valve head 9 leaves valve body 4 under the can, and the material that gets into from the A mouth is from B mouth outflow carrying out can; At this moment, the negative valve Returnning spring 5 of inhaling promotes interior negative suction spool 7 downwards, and the interior negative suction chamber 8 of interior negative suction valve diminishes; Thereby when a last can beat was finished, the liquid material of suction was discharged the negative chamber 8 of inhaling through the hole road of interior negative suction spool 7 and valve head 9 again, and the drip liquid material of sucking-off is discharged and got back to streams when being about to close valve last time.
As shown in figures 1 and 3, thus when the piston rod 17 of cylinder 1 move downward drive outside filling valve close, interior negative suction valve body moves downward, when the air cylinder driven half stroke, valve head 9 is got back to the bottom of valve body 4 under the can.The A mouth is turn-offed, and liquid material stops to flow out from the A mouth, and the piston rod 17 of cylinder 1 continues to move downward.At this moment; Because interior negative suction spool 7 and valve head 9 have arrived the bottom of valve body 4 under the outer can; So continue to move downward can the negative Returnning spring 5 of inhaling of compression for valve body 6 under valve rod 3 and the interior negative suction, the negative chamber 8 of inhaling becomes big in making, thus the hole road of the liquid material that drip converges when valve head 9 turn-offed filling valves through interior negative suction spool 7 and valve head 9 suck in the negative suction valve pocket 8; Can guarantee filling accuracy and filling speed, avoid the drip liquid material to pollute packing material.This fluid filling valve is provided with can Returnning spring 2 and the negative valve Returnning spring 5 of inhaling, and when cylinder 1 was died, valve body 6 all automatically reset and closes under outer can valve body 4 and the interior negative suction, prevent sudden power or when dying material leak.
Combine accompanying drawing and embodiment that the utility model has been done detailed description above; But the utility model is not limited to the foregoing description; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.The content of not doing in the utility model specification to describe in detail all can adopt existing technology.
