Filling valve and process for filling materials using same

Abstract

The invention discloses a filling valve and a process for filling materials using the same. The filling valve comprises a valve plate, wherein a diaphragm valve block, a quantifier, a feeding switch valve, a filling switch valve and a centering frame are arranged on the valve plate; the centering frame pushes the filling switch valve to move up and down; the diaphragm valve block comprises a diaphragm valve and a gas-collecting channel board; a back pressure channel, a gas return channel and an exhaust channel are arranged on the gas-collecting channel board; a filling chamber and an exhaust chamber are arranged in the valve plate; the back pressure channel is connected with the upper end of the quantifier; a gas return pipe is arranged between the gas return channel and the valve port of the filling valve; one end of the exhaust chamber is connected with the valve port of the filling valve, and the other end is connected with the exhaust channel; and a first channel is arranged on the diaphragm valve block. The filling valve of the invention can be used for filling gas bearing materials and also materials free of gas, thereby having wide application range; and because the quantifier is used, the filling accuracy is high.

Description

technical field [0001] The invention relates to a filling valve and a process for filling materials by using the filling valve, in particular to various filling materials including pure water, mineral water, tea, fruit juice, carbonated beverage, beer, etc. Filling valves and filling processes for performance materials. Background technique [0002] Gas-containing and non-gas-containing products packaged in cans have landed in mainland China since the early 1980s due to their refreshing taste, easy preservation, convenient transportation, and environmental protection. After China's first can packaging production line was put into operation in Sanshui, Guangdong in 1984, can packaging equipment began to be used all over the country. According to statistics, domestic can packaging equipment manufacturers are basically concentrated in Zhejiang and Jiangsu, and the technology they use is basically the technology that was distributed to several large state-owned light machine fa...

Problems solved by technology

[0003] 1. Poor self-cleaning ability:

[0004] Because it is a mechanical valve with the principle of equal pressure valve opening, the main body of the filling valve is equipped with a valve opening spring, which is in direct contact with the material; at the same time, there are many mechanical components in the material tank, these factors have led to sanitary dead ends in the filling valve. Many, it is difficult to clean it thoroughly

Such a filling valve has a great impact on product quality, shelf life and taste, especially for pure draft beer, aseptic cold-packed beverages and fruit juices, it is absolutely unacceptable

[0005] 2. Poor controllability:

At the same time, because the filling process is single, when the manufacturer replaces the material container, the process program needs a long time to adjust

In addition, the output of the product is determined by the process time. Different material packaging has differen
