Abstract
The utility model relates to an inner sealing type drop-proof liquid filling valve for liquid filling devices, comprising a valve body 2, a valve rod 1, a valve core 3, a valve seat 6, a liquid inlet 5 and a liquid filling head 8. The utility model is characterized in that the front section of the valve core 3 is provided with a liquid squeezing tongue 7. A corresponding gap between the liquid squeezing tongue 7 and the length of the liquid filling head 8 is very small. Most of the liquid retained in the liquid filling head 8 when the liquid is filled is squeezed in a container, and the minute quantity liquid left in the gap can not be coagulated to form leaking drop liquid to be dropped to pollute container devices and the ground. The utility model solves the problem of drop and leakage of liquid of the liquid filling head of liquid filling devices when the liquid is not filled.
Description
The utility model relates to a kind of pressure type (positive-pressure type) or self-flow type liquid-injection equipment that is used for various liquid, relates in particular to a kind of filling apparatus filling valve.
The fluid-delivery valve that adopts on the present various liquid-injection equipment is forms such as regular tap formula, outer sealed type, interior envelope stop valve formula.Its consistent shortcoming is the water clock that all can not prevent effectively fully after fluid injection from finishing, thereby makes container outer wall, device side, place environment etc. be infected with liquid and contaminated.
The purpose of this utility model is to provide a kind of fluid-delivery valve that solves the water clock liquid problem of liquid-injection equipment after fluid injection finishes effectively.
The utility model is achieved in that a kind of inner sealing formula prevents the drip solution fluid-delivery valve, comprises valve body, valve rod, spool, valve seat, liquid entering hole and filling head, is characterized in that the spool leading portion is provided with liquid-extruding tongue, and liquid-extruding tongue and filling head length respective clearance are minimum.
Compare with existing fluid-delivery valve, the utility model is owing to be provided with a liquid-extruding tongue at the spool leading portion, with residual liquid squeezing container substantially during fluid injection in the filling head, be deposited in minute quantity liquid in the gap and just can't condense and form pollution container, equipment and place under the drip drop.Solved the water clock liquid problem of filling head when not fluid injection of liquid-injection equipment.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
As shown in Figure 1, the utility model comprises valve body 2, valve rod 1, spool 3, valve seat 6, liquid entering hole 5 and filling head 8, and spool 3 lower ends are provided with a liquid-extruding tongue 7, and liquid-extruding tongue 7 is minimum with filling head 8 length respective clearance.Spool 3 and the lapping-in face seal of valve seat 6 junction points.Or settle a seal ring 4 at spool 3 and valve seat 6 junction points, adopt the seal ring sealing.
During fluid injection, spool 3 by valve rod 1 by power (pneumatic, surge, electronic etc.) upwards (interior) move, be higher than liquid entering hole (pipe) liquid mouth passage until liquid-extruding tongue 7 bottoms of spool 3 leading portions, allow liquid pass through liquid entering hole (pipe) and enter container.
Fluid injection finishes, spool 3 by valve rod 1 by power downwards (outward) mobile on spool 3 seal ring 4 (or lapping-in face) contact the liquid of shutting liquid entering hole (pipe) 5 fully, this moment, the liquid-extruding tongue 7 of spool 3 leading portions all entered filling head (pipe) 8, and the liquid that stays during with the middle fluid injection of filling head (pipe) is clamp-oned container substantially.Make the Micro-volume liquid that remains in liquid-extruding tongue 7 and filling head inwall gap can't be condensed into a water clock and get off, finish complete leakage-proof function.
Claims (3)
