The upper-end surface of described spool with guiding valve body lower end surface between linear sealing contact; Described valve rod upper-lower seal in sealing seat is slided.
Also comprise the sealing seat locknut that is screwed in described upper connector inwall, the lower end of described sealing seat locknut compresses and contacts with sealing seat upper end.
Also comprise locking the spool locknut of described valve rod and spool.
Described spool upper-end surface is outer spherical surface structure; The lower end surface of described guiding valve body is cone structure.
Described filling straight tube and feed liquor straight tube adopt homopolymerization type polypropylene PP-H moulding materials in the tube; Upper connector, lower link and guiding valve body adopt the machine shaping of PP-H bar, and upper connector, the sweat soldering of lower link difference are in the two ends up and down of filling straight tube; Described valve rod, spool, spool locknut, sealing seat, sealing seat locknut all adopt polytetrafluoroethylene PTFE bar to process.
Beneficial effect of the present invention:
Adopt high molecule plastic to do the agent structure of filling valve, can resist the corrosion of the liquid such as the strong acid of pH value from 0～14, highly basic; There is the advantages such as simple in structure, easy to operate, with low cost, be applicable to automatic filling machine under the liquid level of chemical field.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1, filling straight tube 12 sides are communicated with feed liquor straight tube 13 to assembly relation of the present invention; Filling straight tube 12 lower ends are coaxially connected with the lower link 5 of tubular structure, and guiding valve body 3 upper end stuffing box glands are connected on described lower link 5, at the internal face of described lower link 5 outer wall and described guiding valve body 3, seal ring 4 are set;
Filling straight tube 12 upper ends are coaxially connected with the upper connector 7 of tubular structure, sealing seat 10 be arranged on upper connector 7 inner and with the internal face interference fit of described upper connector 7; Between described sealing seat 10 outer wall and the internal face of described upper connector 7, be provided with exterior seal ring 9; Sealing seat locknut 11 is screwed on the inwall of described upper connector 7, and the lower end of sealing seat locknut 11 compresses and contacts with sealing seat 10 upper ends;
Valve rod 6 is from top to bottom through sealing seat locknut 11, sealing seat 10, guiding valve body 3, and its lower end and spool 1 are threaded connection, and by 2 lockings of spool locknut; Described spool 1 upper-end surface is outer spherical surface structure; The lower end surface of described guiding valve body 3 is cone structure;
The outer spherical surface structure of described spool 1 with guiding valve body 3 cone structure between linear sealing contact; Between described valve rod 6 and described sealing seat locknut 11, guiding valve body 3, all leave gap; Between described valve rod 6 and sealing seat 10 inwalls, be provided with inner seal ring 8, described valve rod 6 slides in the interior sealing of sealing seat 10;
All parts that the present invention contacts with liquid all adopt non-metallic material, except seal ring 4, inner seal ring 8 and exterior seal ring 9 adopt fluorine rubber FPM material, all the other all adopt high molecule plastic, and wherein filling straight tube 12 and feed liquor straight tube 13 adopt homopolymerization type polypropylene PP-H moulding materials in the tube; Upper connector 7, lower link 5 and guiding valve body 3 all adopt the machine shaping of PP-H bar, and wherein, after upper connector 7 and lower link 5 machine shapings, sweat soldering is in the two ends up and down of filling straight tube; Remaining parts adopts polytetrafluoroethylene PTFE bar to process.
Working procedure of the present invention is as follows:
For guaranteeing filling accuracy and avoiding the problem of spuming, during work, can select two kinds of modes, to being not easy liquid foamy, to carry out two stages of large and small flow filling; Easy liquid foamy is carried out to little, large and small three phases filling.The small-large flow of valve is controlled (modulating valve is for example installed) by feed liquor straight tube 13 ends, and the driving on valve rod 6 tops is the switch of control valve.According to first kind of way, working procedure is described below: when Plastic Drum 14 enters after filling station, filling valve of the present invention declines and enters bung and inserts its bottom (needing the reserved valve space of opening), from upper end actuate valve stem 6 along sealing seat locknut 11, sealing seat 10 and guiding valve body 3 through hole move down, spool 1 and guiding valve body 3 depart from drives valve, first carries out large flow filling; Filling closing on while finishing, rises to filling valve on liquid level, carries out small flow filling until meet filling accuracy, and actuate valve stem 6 moves up, and the linear sealing of cone-shaped of the outer spherical surface of spool 1 and guiding valve body 3 lower ends closes valve; Finally filling valve is continued to rise to peak, the Plastic Drum 14 of filling material leaves filling station, and filling valve etc. are pending next time filling.
