Filling valve for filling machine

Abstract

The invention provides a filling valve for a filling machine. The filling valve comprises anti-freezing components which are fixedly arranged at the central positions of the outer surfaces of the front side, the rear side and the left side of a valve body and can prevent the valve body from being frozen, wherein each anti-freezing component comprise a shell, pretreatment components capable of making preparation in advance before residual liquid in the valve body is frozen, and heating components capable of rising the temperature outside the valve body; the shells are fixedly installed in the centers of the outer surfaces of the front side, the rear side and the left side of the valve body; the pretreatment components are movably installed at the left end and the right end in each shell correspondingly; and the heating components are movably installed between the center in each shell and the left and right lower ends. According to the filling valve for the filling machine, the anti-freezing function can be achieved outside the valve body, when the filling valve is subjected to liquid filling in the winter environment of northern China and stands still, even if the temperature outside the valve is low, residual liquid in the valve is not prone to freezing, the possible freezing fault can be eliminated in time, the filling valve is prevented from being damaged by freezing, and the subsequent use effect is ensured.

Description

technical field [0001] The invention relates to the field of filling machinery and equipment, and more specifically relates to a filling valve for a filling machine. Background technique [0002] The traditional filling valve is filled through the standard pneumatic angle seat valve control switch, which only has two actions of opening and closing, and does not play a buffer role in the stamping of the material during filling, which will cause anti-foaming of the material, Inaccurate filling volume and other problems, as well as the length of the filling mouth can not be effectively controlled, resulting in dripping after the valve is closed, polluting the bottle mouth; in addition, due to the frequent movement of the filling valve, the pneumatic angle seat valve After the unit seal is worn out, material leakage and channeling will occur, which will have a great impact on the hygienic requirements and filling accuracy of filling. [0003] In view of the above problems, rega...

Problems solved by technology

[0004] However, the technical solution provided by this patent does not have the antifreeze function for the valve body. When the filling valve is filled with liquid in the winter environment in northern China and stands still, due to the low temperature outside the valve, the residual liquid in the valve is prone to break out. Icing, if the icing failure is not eliminated in time, there will be technical problems that will freeze the filling valve and affect subsequent use
