Solenoid valve needs improvement to adapt to the rapid technological development of vacuum packaging machinery

The production of vacuum packaging machinery in China began in the 1970s and developed rapidly. Starting from the introduction of imported technologies, the starting point was relatively high. After 30 years of development, it has been able to produce a wide range of vacuum inflator filters. In addition to Xinjiang, Tibet, and Qinghai, a few provinces and regions, the production enterprises throughout the country, but among which the vacuum packaging machine as the leading product of a small number of enterprises, most of them are small and medium-sized enterprises concurrently, many companies production It is based on assembly. China's products are relatively complete in their existing varieties and can basically meet the needs of the market. The main varieties are single-chamber, double-chamber, butterfly-belt conveyor, intubation, rotary vacuum chamber, thermoforming, mixed gas inflation, etc. The main operation is the automatic continuous type, large steam trap vacuum chamber and vacuum packaging machine suitable for liquid packaging. Lack of efficient, dedicated vacuum packaging machines.

Most of our vacuum nitrogen filling packaging machines are developed on the basis of the digestion and absorption of foreign technology, and the gap between the design and the structure is not obvious compared with similar foreign models, but there are problems such as the quality of the accessories, etc. There is still a gap between the reliability of use and similar foreign models.

The application of high technology has led to continuous improvements in the overall design of vacuum inflatable packaging machinery. Ball Valves is used for filling mixed gases, heat pipe sealing technology, and high-vacuum electromagnetic valves. Developed countries have generally adopted high technology. China has a clear gap in this regard and needs further development. Some varieties, such as vacuum packaging, are also Fill in the blanks.

In the future, China should continue to track the advanced technologies of foreign vacuum packaging machines, accelerate the application of high and new technology, fill in blank varieties, and attach importance to the production of components and parts, increase reliability, and expand the scope of use.
