Working process of the present invention is:
One, tank is entered
As shown in Fig. 1,4, before filling, pneumatic diaphragm control cock 16 is in open mode, and outer sliding sleeve 21, under the effect of valve closing spring 5, is pressed on seal spool pad 18, closes filling valve; Material 23 to be filled enters in the filling passage 29 in filling valve by material cylinder 24, filling arm 25, because valve is in closed condition, therefore material 23 is back in reflux accumulator 14 by the return flow line between spool pipe box 19 and spool 20 through reflux line 15, to maintain valve inner constant temperature.When filling valve rotates with bottle placer, roller 10 rises with the curve of lifting shaft 12 along lifter cam 9; Container 2 is then by the filling station dialled below tank star-wheel feeding filling valve, then the curve of lifter cam 9 declines, decline along lifter cam 9 curve under top stage clip 11 acts on, the opening opening's edge of container 2 progressively sealed packing seal 3 seals, compress until opening opening's edge seals with sealing seat 22, form an airtight filling space between container 2 and filling valve, start to enter filling action.
Two, filling
As shown in Fig. 2,3,5,
Completing along with entering tank step, pneumatic diaphragm control cock 16 being closed by source of the gas, the material 23 in return flow line stops backflow, and filling material 23 keeps filling valve temperature stabilization, now, cam curve continues to decline, and now because the elastic force of top stage clip 11 is greater than the elastic force of valve closing spring 5, therefore, relative sliding is there will be between lower valve base 6 and outer sliding sleeve 21, namely lower valve base 6 is stressed and move down, and then band movable valve plug 20 moves down, sealing fit portion 201 is separated with the face of being sealed and matched of outer sliding sleeve 21, open filling valve, material 23 is under minute-pressure or self gravitation, slowly flow into inner along container 2 inwall, in container 2, air is discharged along with the volume increase of liquid, via the center return-air hole of spool 20, centre hole 17, return-air duct 13 and be back in reflux accumulator 14, material 23 is full of bottom container 2 to spool 20 within a certain period of time, electrolyte level H1 remains unchanged, when not depart from filling valve port be sealing state to container 2, material 23 in material cylinder 24 continues to flow in container 2, now unnecessary material 23 rises along spool 20 center return-air hole, reaching surely high H2 to stop, keeping stabilized conditions to going out tank.
Three, tank is gone out
When filling valve rotates to out tank position on bottle placer, roller 10 and lifting shaft 12 rise along lifter cam 9, lifting shaft 12 rises and drives valve seat to rise, and valve closing spring 5 makes outer sliding sleeve 21 be pressed on seal spool pad 18 by elastic force effect, is closed by filling valve and stops filling; Container 2 with sealing packing seal 3, seal seat 22 and be separated; Be in material 23 in the return-air hole of spool 20 center under gravity, also flow in container 2, till filling valve port departs from 2 mouthfuls, container; Now according to material 23 manufacturing technique requirent, when entering the next filling cycle, pneumatic diaphragm control cock 16 is selected to open or close (reflux or do not reflux); Final container 2 enters closure system after pushing away Tank-supporting device 1 by other mechanisms.
This thermal loading valve advantage have following some:
1. return gas channel separates completely with return flow line, and imperial mandate is sick to avoid gas-liquid mixed, production capacity that the same passage that coexists brings is unstable etc.;
2. adopt and separate Membrane cover, the passage contacted with material in valve is completely without corner or spot as yet untouched by a clean-up campaign, and food security is able to great guarantee;
3. take pneumatic diaphragm change-over valve, control the backflow keeping the inner constant temperature material of filling valve, and its quantity of reflux can be adjusted arbitrarily according to different material characteristic, various processes process requirements;
4. valve body precision is high, and makes material reach H2 height time filling, and filling accuracy of measurement is higher, and deviation is at ± below 3mL;
5. comparatively Electronic Valve is simple, easily manufactured for this thermal loading valve physical construction, and structure is convenient to cleaning, easy to maintenance;
6. bottom clearance controls liquid level conveniently, simply, only need change packing ring 4 and can control to seal the height between seat 22 and container 2 opening opening's edge, make Liquid level convenient.
