Combination air-operated valve for sterilized filling machine

Abstract

The invention discloses a multifunctional combine pneumatic valve applied on aseptic filling machine, which comprises a valve body. The valve body is composed of a first cavity, and a second cavity, a third cavity and a fourth cavity which are respectively connected with the first cavity, and a fifth cavity connected with the fourth cavity, the other end of the second cavity is connected with a first pneumatic execution member through a second coupler, the other end of the third cavity is connected with a second pneumatic execution member through a third coupler, and the other end of the fifth cavity is connected with a third pneumatic execution member through a fourth coupler. The multifunctional combine pneumatic valve applied on aseptic filling machine has simple structure, and can realize the functions of filling, heat sterilization and the like. When a plurality of aseptic filling machines are used, the filling pipelines of the filling machines are relatively isolated, so the material can not be polluted.

Description

technical field [0001] The invention relates to an aseptic filling machine, in particular to a combined pneumatic valve used in the aseptic filling machine. Background technique [0002] With the continuous improvement of people's living standards and the rapid development of the beverage industry, aseptic filling has become a very popular filling method, especially widely used in dairy packaging. At present, filling machines on the market must use a lot of pneumatic valves in order to realize functions such as automatic filling and heat disinfection during the filling process. The structure of the existing start-up valve mainly includes: valve body and valve body Connected pneumatic actuators, pneumatic actuators include: a housing, a cavity and a valve stem are arranged inside the housing, a piston plate is arranged on the valve stem in the cavity, and the piston plate divides the cavity into an upper cavity and a lower cavity. There are two parts of the cavity, an air ou...

AI Technical Summary

Problems solved by technology

Moreover, the connecting pipeline on each pneumatic valve is also very complicated. To realize the switching between functions such as filling and thermal disinfection, more pneumatic valves and connecting pipelines will be used, too many pneumatic valves and complicated connecting pipes Road is not conducive to cleaning and sterilization

When multiple aseptic filling machines are used online in the aseptic filling production line, the filling pipelines of each aseptic filling machine need to be relatively isolated, otherwise, when some aseptic filling machines are cleaning and sterilizing operation, when the rest of the aseptic filling machines are filling normally, the materials in the normally operating aseptic filling machines are easily contaminated
