Abstract
The utility model discloses a mechanical pump valve used for liquid filling, which comprises a liquid inlet valve cage (2), a liquid outlet valve cage (3), a pump body(5), a liquid outlet mouth (4), a liquid inlet mouth (1), a rubber hose(13), a rubber hose (9) and a piston (8), it is characterized in that the lower part of said piston (8) is provided at least two locating plunger slots (12, 14) and said locating plunger slots (12, 14) are provided with inclined joint locating rings (10, 15), and the front end of said piston (8) is provided with a seal ring (11). The utility model is a mechanical pump valve used for liquid filling with high measuring and repetition precision of whole machine filling, simple structure, convenient operation and easy manufacturing.
Description
Technical field
The utility model relates to a kind of mechanical pump valve, particularly relates to a kind of mechanical pump valve that is used for filling liquid.
Background technology
At the filling liquid of filling liquid during particularly pharmaceuticals industry is produced, the piston of the mechanical pump valve that adopts is the piston ring that polytetrafluoroethylene is done at present, this piston ring is not wear-resisting, the normal filling accuracy that influences complete machine, and the mechanical weight conical surface seal mode that its change-over valve adopts, the liquid that viscosity is bigger commutates function influence clearly to it.
The utility model content
Technical problem to be solved in the utility model provides the mechanical pump valve that a kind of complete machine filling measurement repeatable accuracy is high and simple in structure, easy to operate, manufacturing simply is used for filling liquid.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise piston, the pump housing, liquid inlet port, fluid mouth, at least be provided with the twice positioning groove in the piston bottom and in described positioning groove, be provided with the mitre joint steady ring, be provided with seal ring in described piston nose.
As a kind of improvement of the present utility model, described positioning groove is annular positioning groove and is provided with the polytetrafluoroethylene steady ring in described annular positioning groove, is provided with viton seal ring in described piston nose.
Adopt the mechanical pump valve that is used for filling liquid of technique scheme, owing to be provided with the twice positioning groove in the piston bottom at least and in described positioning groove, be provided with polytetrafluoroethylene mitre joint steady ring, be provided with viton seal ring in described piston nose, piston down moves during imbibition, form vacuum in the pump housing, flow of liquid is through liquid inlet port, sebific duct and feed liquor valve enter in the pump housing, sebific duct on the fluid mouth seals up the fluid mouth because of being subjected to external pressure, when pushing away on the piston, liquid is through the fluid mouth, sebific duct and fluid valve body are pumped out, and the sebific duct of feed liquor seals up liquid inlet port because of the pressure that soup flows, described polytetrafluoroethylene steady ring and described viton seal ring are wear-resisting, improved complete machine filling measurement repeatable accuracy, and it is simple in structure, be convenient to operation, cost is low, so the utility model is that a kind of complete machine filling measurement repeatable accuracy is high and simple in structure, easy to operate, make the mechanical pump valve that simply is used for filling liquid.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Referring to accompanying drawing, in the pump housing 5, be provided with piston 8, circular nut 7 is packed in the described pump housing 5 on the pump seat 6, be provided with twice annular positioning groove 12,14 in piston 8 bottoms and in described positioning groove 12,14, be provided with polytetrafluoroethylene mitre joint steady ring 10,15, be provided with viton seal ring 11 at described piston 8 front ends.
Adopt the mechanical pump valve that is used for filling liquid of technique scheme, piston 8 down moves during imbibition, form vacuum in the pump housing 5, flow of liquid enters in the pump housing 5 through liquid inlet port 1, sebific duct 9 and feed liquor valve 2, sebific duct 13 on the fluid mouth 4 seals up fluid mouth 4 because of being subjected to external pressure, when pushing away on the piston 8, liquid is pumped out through fluid mouth 4, sebific duct 13 and fluid valve body 3, and the sebific duct 9 of feed liquor seals up liquid inlet port 1 because of the pressure that soup flows, thereby an imbibition and discharge opeing process have been finished, so move in circles, liquid is just constantly pumped.Because polytetrafluoroethylene steady ring 10,15 and described viton seal ring 11 are wear-resisting, have improved complete machine filling measurement repeatable accuracy, and simple in structure, be convenient to operation, cost is low.
