1. be the gravity can owing to what adopt, so filling speed is slow, and filling speed is just influenced greatly by can cylinder liquid level.During high liquid level, the pressure of valve port is big, and flow rate of fluid is fast; When hanging down liquid level, the pressure of valve port is little, and flow rate of fluid is slow;

2. owing to need to open valve events twice, move loaded down with trivial detailsly, cause complex structure, part is many, making and maintenance cost height.

3. be profusely can during can, can not adjust liquid level according to client's demand, and profusely can overflowed easily in subsequent production process medium, pollutes bottleneck and body, cause the medium waste.

Summary of the invention

Technical matters to be solved by this invention is: provide a kind of simple in structure, filling speed is fast, and can guarantee the efficient wine filling valve of different liquid levels according to the different demands with the client of different doleiforms, and can be used for not gassiness normal temperature can of can.

For solving the problems of the technologies described above, the technical solution used in the present invention is: filling valve is loaded on a fluid cylinder bottom, comprise: valve body and feed liquor cover, but feed liquor puts and has inlet opening, valve pocket links to each other with valve bonnet, the bottleneck packing seal is housed below the valve bonnet, when bottle rises under proposing the bottle effect, jack-up bottleneck packing seal, and the packing seal on valve pocket and the spool is broken away from, form medium channel, can open the valve can, muffler A is equipped with in the spool bottom, and muffler A puts in the liquid level that the interior position of bottle is requirement during can, and the muffler B that the top is higher than the liquid level in the fluid cylinder is equipped with on spool top, more than the liquid level of fluid cylinder top, there is the negative pressure pipe to connect negative pressure pump, the effect of negative pressure pump has two when can: the one, take out the air in the bottle, and cause negative pressure in the bottle, thereby accelerate filling speed.The 2nd, take out filling valve and irritate unnecessary medium in the bottle into, make liquid level guarantee position all the time in muffler A lower end.
