To achieve these goals, the technical solution of the utility model is: a kind of three-way valve filling and sealing device, be used in the filling measurement device of wrapping machine, described filling measurement device is a kind of triple-wave piston formula metering filling device, is provided with lower thimble for opening and closing material sucking port and for opening and closing the upper thimble of filling exit; Between described three-way valve valve body and lower thimble, be provided with lower thimble seal ring; Between described three-way valve valve body and upper thimble, be provided with thimble seal ring.
Further, be provided with lower seal groove cavity in the lower thimble outlet port of three way valve, described lower thimble seal ring is arranged in described lower seal groove cavity, is provided with lower thimble seal ring is fixed on to the lower end cap in lower seal groove cavity on three way valve; Upper thimble outlet port at three way valve is provided with seal groove, and described upper thimble seal ring is arranged in described upper seal groove, is provided with upper thimble seal ring is fixed on to the upper end cap in seal groove on three way valve.
Further, described lower thimble seal ring and upper thimble seal ring are O shape rubber seal or U-shaped inner frame rubber seal.
Further, the material of described lower thimble seal ring and upper thimble seal ring is fluorine rubber.
The beneficial effects of the utility model are: adopt O shape rubber seal or U-shaped inner frame rubber seal, upper thimble to three-way valve and lower thimble seal, three-way valve cavity and extraneous buffer action are reached, significantly improve the working life of three-way valve filling and sealing device, reduced because changing the diaphragm loss causing that stops production; Simple in structure, can transform existing equipment easily.
Below in conjunction with drawings and Examples, the utility model is described in detail.

Embodiment
As Fig. 1, a kind of three-way valve filling and sealing device, is used in the filling measurement device of wrapping machine, and described filling measurement device is a kind of triple-wave piston formula metering filling device, is provided with lower thimble for opening and closing material sucking port and for opening and closing the upper thimble of filling exit; Between described three-way valve valve body and lower thimble, be provided with lower thimble seal ring; Between described three-way valve valve body and upper thimble, be provided with thimble seal ring.
Described lower thimble seal ring and upper thimble seal ring are O shape rubber seal or U-shaped inner frame rubber seal.
Embodiment one:
As Fig. 1, a kind of three-way valve filling and sealing device, is used in the filling measurement device of wrapping machine, and the wrapping machine in the present embodiment is the TF-02 type wrapping machine that You Nifeier (UNIFILL) company produces, and packs for liquid drug.
The filling measurement device of TF-02 type wrapping machine is a kind of triple-wave piston formula metering filling device, is provided with lower thimble 11 for opening and closing material sucking port 31 and for opening and closing the upper thimble 21 of filling exit 32; Between described three-way valve valve body 30 and lower thimble, be provided with lower thimble seal ring 12; Between described three-way valve valve body and upper thimble, be provided with thimble seal ring 22.
The diameter of lower thimble and upper thimble is 5mm; Lower thimble seal ring and upper thimble seal ring are O shape rubber seal, and internal diameter of the seal ring is 4.8mm, and seal ring diameter of section is 1.9mm, and the material of seal ring is fluorine rubber.The material of seal ring can be according to selected by filling material characteristic.
Lower thimble outlet port at three way valve is provided with lower seal groove cavity 33, and described lower thimble seal ring is arranged in described lower seal groove cavity, is provided with lower thimble seal ring is fixed on to the lower end cap 35 in lower seal groove cavity on three way valve; Upper thimble outlet port at three way valve is provided with seal groove 34, and described upper thimble seal ring is arranged in described upper seal groove, is provided with upper thimble seal ring is fixed on to the upper end cap 36 in seal groove on three way valve.
