Abstract
The utility model discloses a low vacuum filling valve, comprising a valve body; the valve body is arranged at the bottom of a liquid storing tank and is communicated with the liquid storing tank; a valve core capable of moving up and down and limited by elasticity is arranged in the valve body; a filling nozzle is connected with the lower end of the valve core; an air outlet pipe penetrates the valve core and the filling nozzle; the upper end of the air outlet nozzle penetrates out of the valve body to be connected with the valve body; a boss is arranged at the lower end of the air outlet pipe; a draining sealing pad is arranged between the upper surface of the boss and the lower edge of the filling nozzle; a bottle nozzle sealing pad is arranged at the outer surface of the lower part of the filling nozzle; the upper surface of the draining sealing pad is a slope gradually descended from inside to outside. The low vacuum filling valve has the beneficial effects that the upper surface of the draining sealing pad adopts the slope, the stress is uniform, and the sealing effect is good. Dual guide slide sleeves made of teflon material are adopted, so the guide effect is good, the machining is easy, the friction coefficient is small, the elasticity is large, and economical and durable effects are realized. The position of the bottle nozzle sealing pad can be adjusted according to different bottles through an adjusting ring, and the applicable range is wide.
Description
Technical field
The utility model relates to a kind of low vacuum filling valve.
Background technology
At present, vacuum type bottle placer is to utilize the vacuum system configuring in bottle placer, makes packing container in certain degree of vacuum, thereby makes the liquid material of liquid reserve tank inject packing container under certainization pressure reduction or vacuum state.On vacuum type bottle placer, all will configure low vacuum filling valve and realize filling function, conventional filling valve is generally used the sealing of O RunddichtringO at filling nozzle place on the market, and O RunddichtringO sealing effectiveness is poor, easily leaks.On spool, adopt copper single guide sleeve, guide effect is poor, and copper is not only easy to wear, and does not meet hygienic requirements.
Summary of the invention
For solving above technical deficiency, it is a kind of simple in structure, easy to use that the utility model provides, good sealing effect, the low vacuum filling valve of long service life.
The utility model is realized by following measures:
A kind of low vacuum filling valve of the present utility model, comprise the valve body that is arranged on fluid reservoir bottom and is communicated with fluid reservoir, in valve body, be provided with the spool that can move up and down and be subject to elastic force restriction, spool lower end is connected with filling nozzle, in spool and filling nozzle, be penetrated with freeing pipe, freeing pipe upper end passes valve body and is connected with valve body, freeing pipe lower end is provided with boss, between boss upper surface and filling nozzle lower edge, be provided with discharge opeing packing seal, filling nozzle lower external face is provided with bottle neck packing seal, and the upper surface of described discharge opeing packing seal is the inclined-plane reducing gradually from inside to outside.
The guide sleeve that has a polytetrafluoro material is all overlapped in the upper and lower of above-mentioned spool, and guide sleeve is between spool and valve body.
On above-mentioned filling nozzle, overlap the adjustment ring that can slide up and down, in described adjustment ring, be provided with binding bolt, bottle neck packing seal is connected to the bottom of adjustment ring.
The beneficial effects of the utility model are: discharge opeing packing seal upper surface adopts inclined-plane, stressed even, good sealing effect, and when filling, liquid presents umbrella, and filling speed is fast, and not excessive.Adopt two guide sleeves of polytetrafluoro material, guide effect is good and easily process, and friction coefficient is little, and elasticity is large, economy and durability.
By adjustment ring, can according to different bottles, adjust the position of bottle neck packing seal, applied widely.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks cross-sectional view.
Fig. 2 is the structure for amplifying schematic diagram of A in Fig. 1.
Wherein: 1 freeing pipe, 2 valve bodies, 3V RunddichtringO, 4 spools, 5 guide sleeves, 6 retracing springs, 7 filling nozzles, 8 adjustment rings, 9 bottle neck packing seals, 10 discharge opeing packing seals, 11 fluid reservoirs.
The specific embodiment
As shown in Figure 1, 2, a kind of low vacuum filling valve of the present utility model, comprise the valve body 2 that is arranged on fluid reservoir 11 bottoms and is communicated with fluid reservoir 11, in valve body 2, be provided with spool 4 moving up and down, between valve body 2 and spool 4, cover has retracing spring 6, is subject to elastic force restriction and can in the situation that stressing, reset in spool 4 moves up and down process.Spool 4 upper ends are provided with V-shaped seal ring 3, prevent that liquid from flowing between spool 4 and valve body 2.Spool 4 lower ends are connected with filling nozzle 7, in spool 4 and filling nozzle 7, be penetrated with freeing pipe 1, freeing pipe 1 upper end passes valve body 2 and is connected with valve body 2, freeing pipe 1 lower end is provided with boss, between boss upper surface and filling nozzle 7 lower edges, be provided with discharge opeing packing seal 10, the upper surface of discharge opeing packing seal 10 is the inclined-plane reducing gradually from inside to outside, discharge opeing packing seal 10 is fully contacted with filling nozzle 7 edges, stressed even, when filling, liquid presents umbrella, filling speed is fast, and not excessive, than original O RunddichtringO good sealing effect.
The upper and lower of spool 4 is all overlapped the guide sleeve of a polytetrafluoro material 5, and guide sleeve 5 is between spool 4 and valve body 2.Adopt two guide sleeves 5 better than original single guide sleeve 5 guide effect, and easily processing, guide sleeve 5 materials change polytetrafluoro into by original copper, and copper is not only easy to wear, and does not meet hygienic requirements, and polytetrafluoro friction coefficient is little, and elasticity is large, economy and durability.
Filling nozzle 7 lower external face are provided with bottle neck packing seal 9.On filling nozzle 7, overlap the adjustment ring 8 that can slide up and down, in adjustment ring 8, be provided with binding bolt, bottle neck packing seal 9 is connected to the bottom of adjustment ring 8.By adjustment ring 8 is adjusted to differing heights, to realize when filling different bottle, filling nozzle 7 stretches into the different degree of depth of bottle.
Its principle of work is: valve body 2 is arranged on fluid reservoir 11 bottoms, and liquid is full of the cavity in valve body 2, until discharge opeing packing seal 10, the pressure reduction of liquid is obvious, and liquid flow velocity is fast; After bottle contacts with bottle neck packing seal 9, bottle moves under the effect of other power, on filling nozzle 7 and spool 4, move, thus filling nozzle 7
Leave gradually discharge opeing packing seal 10, liquid flows into the interior beginning of bottle from filling nozzle 7 bottoms filling, and the gas in bottle enters from freeing pipe 1 lower end, from liquid level top, discharges.Between valve body 2 and spool 4, guide sleeve 5 is installed, can plays the effect of guiding, increased the service life of valve.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
