Abstract

The invention provides a liquid filling valve and an operating method thereof. The liquid filling valve comprises a valve body, wherein a valve core is arranged in the valve body, the top of the valve body is sealed by a sealing diaphragm of the valve core, a discharge opening which is aligned with a container is formed in the bottom of the valve body, a filling channel is formed between the inner wall of the valve body and the valve core, the filling channel is connected to a feed pipe by virtue of a flowmeter, and a push device which is used for pushing the sealing diaphragm of the valve core to move is arranged on the top of the valve body. The liquid filling valve is characterized in that a pre-closed valve clack sleeves the upper part of the valve core, a clearance is left between the valve core and the pre-closed valve clack, the pre-closed valve clack can freely move up and down along the valve core, and a valve port sealing ring is arranged between the bottom of the valve core and the discharge opening in the lower end of the valve body. The liquid filling valve has the advantages of sanitation, no cleaning dead angle and low cost, and the splashing phenomenon is fully eliminated when the filling valve is closed.

Description

technical field [0001] The invention relates to the field of filling valves, in particular to a non-contact liquid filling valve and a working method thereof. Background technique [0002] Non-contact liquid filling valves are widely used in industries such as beverages, condiments, detergents, etc., especially as an indispensable part in aseptic filling equipment for beverages. [0003] But the general contactless filling valve, see Figure 4 , there is a big disadvantage, that is, it is easy to cause liquid splashing at the moment of closing the valve, see Figure 5 , causing loss of the filled material and contamination of the outer surface of the filled container. [0004] In order to solve the splashing problem when the filling valve is closed, the existing methods are: [0005] a. Reduce the flow rate of the filling valve, because the cause of the splashing problem is: when the valve is closed, the area of ​​the valve port decreases, the flow rate of the liquid incre...
