Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As depicted in figs. 1 and 2, a kind of Self negative suction anti-dropwise-leakage filling valve, the valve port 1 comprising valve body 9, be tightly connected with valve body 9 lower end, valve body 9 upper end has inlet point 11, the center of the material cavity 13 that valve body 9 and valve port 1 surround is provided with valve rod 10 and spool 2, valve rod 10 upper end is through valve body 9 top, and valve rod 10 lower end and spool 2 seal sliding block joint, and lower end and the valve port 1 of spool 2 are fitted.Be connected by seal ring 12 between valve rod 10 with spool 2, valve rod 10 lower end is provided with piston 6, is provided with spring 3 between piston 6 and spool 2 inside lower end face, and spool 2 inside is provided with in-core guidepost 5, and described in-core guidepost 5 is connected with piston 6 inner seal; Formed between seal ring 12 and piston 6 to bear and inhale chamber A, between piston 6 and in-core guidepost 5, form adapter cavity B; The center of valve rod 9 lower end, spool 2 lower end and in-core guidepost 5 all has the hole communicated with piston cavity, and spool 2 bottom has the hole communicated with material cavity 13, and valve rod 10 has and is communicated with negative hole of inhaling chamber A and piston cavity.Be provided with outer guide sleeve 7 between valve body 9 and spool 2, outer guide sleeve 7 lower end is provided with sleeve 4.Spool 2 and outer guide sleeve 7 cooperatively interact, can relative sliding, and outer guide sleeve 7 pairs of spools 2 play directional tagging, make the O-ring conical surface on its accurate and valve port 1 bonded to each other, complete sealing and the closing movement of filling valve.
Working process and the principle of a kind of Self negative suction anti-dropwise-leakage filling valve provided by the invention are as follows:
When filling valve is closed, as shown in Figure 3, outside actr band ovable valve stem 10 moves downward, and valve rod 10 is with movable valve plug 2 to move downward together, and when spool 2 is fitted with valve port 1 sealing surface, filling valve is closed, and stops filling.Now, actr band ovable valve stem 10 overcomes spring 3 elastic force to be continued to move downward, now the volume of the negative chamber A of suction increases, the volume of adapter cavity B reduces, volume due to negative suction chamber A is pushed the speed and is greater than the reduction speed of adapter cavity B, so form a negative pressure state at spool 2 center pore, the salvage stores of spool 2 bottom can be sucked negative suction chamber A by this negative pressure state.
When filling valve is opened, as shown in Figure 4, actr band ovable valve stem 10 upward movement, valve rod 10 lower end piston 6 is upward movement simultaneously, and due to the effect of spring 3, now spool 2 and valve port 1 are still in the state of fitting tightly.Because spool 2 is static, piston 6 upward movement, the volume of the negative chamber A of suction reduces, adapter cavity B volume increases simultaneously, and the volume of the negative chamber A of suction reduces speed and is greater than pushing the speed of adapter cavity B, so, in negative suction chamber A, the centre hole by spool 2 is discharged by unnecessary material, pours into container filling.Thus do not produce the waste of any material.
