The invention relates to a perfusion valve comprising a mechanism main body and at least one group of loop pipelines arranged in the mechanism main body for perfusion, wherein the loop pipelines comprise a first loop pipeline connected with a main pipeline, a cylinder connected with the first loop pipeline, a first air inlet connected with the cylinder and a piston rod connecting component arranged in the cylinder, the cylinder comprises an upper cylinder chamber and a lower cylinder chamber, and the loop pipelines further comprise a second loop pipeline which is arranged on one side of the cylinder and communicated with the upper cylinder chamber, a second air inlet communicated with the second loop pipeline, a third loop pipeline which is arranged on one side of the cylinder and communicated with the lower cylinder chamber and a perfusion port communicated with the third loop pipeline. Compared with the prior art, the perfusion valve has the beneficial effects that, the way of performing ventilation at the two ends of the piston rod connecting component is used for on-off control of a loop, thereby prolonging the service life of the perfusion valve.
Description
technical field [0001] The invention relates to a filling valve, in particular to an automatic vacuum filling valve. Background technique [0002] With the rapid development of my country's wine industry, the output of beer, wine, rice wine, liquor and other alcoholic beverages has continued to grow. The total output of beverage alcohol (excluding fruit wine and fermented alcohol) in my country has reached 28.78 million liters, a year-on-year increase of 8.2%. Relevant experts pointed out that my country's beverage industry is a high-growth industry. The growth of mature beverages is stable, new hot spots and growth points are constantly emerging, and the growth of emerging beverages is faster. At the same time, China's packaging machinery has developed into an industry with great influence and a huge market share in the world's liquid food industry. Therefore, the liquid filling machine market has great potential for development. [0003] The core component of the liquid ...
