Mechanical hot-filling valve

Abstract

The invention relates to a mechanical hot-filling valve, comprising an upper valve body and a lower valve body which can move relatively, wherein a filling cavity is formed in the upper valve body and the lower valve body; the upper part of the filling cavity is provided with a feeding port, the lower part of the filling cavity is provided with a discharging port, the middle part of the filling cavity is provided with a convex ring and a valve rod; the upper end of the valve rod is connected with the upper valve body; the valve rod is provided with a flow guide ring which is internally provided with a flow guide hole; the outer wall of the flow guide ring is butted with the convex ring; the middle part of the valve rod is provided with an air return pipe; the filling cavity is internally provided with a sealing ring made of elastic materials; the upper end of the sealing ring is clamped in the upper valve body, and the lower end of the sealing ring is provided with a T-shaped groove; and the upper wall of the lower valve body is internally provided with a T-shaped convex part which is clamped in the T-shaped groove. The mechanical hot-filling valve has the advantages that since the sealing ring is added at the sliding part of the filling valve, dead corners at the moving and fixed positions of the filling valve are avoided, no residual is generated in filling and cleaning and the quality of a filled product is improved.

Description

technical field [0001] The invention relates to the field of beverage hot filling, in particular to a mechanical hot filling valve. Background technique [0002] PET hot filling is widely used in China, and mechanical valves are used. There are large dead angles between the moving parts and static parts of these valves, which are not easy to clean. Due to the high sugar content of hot-filled beverages, if the valve cannot be cleaned thoroughly, fouling will occur for a long time, which will affect the quality of the filled product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanical hot filling valve that can improve the cleaning condition of the mechanical hot filling valve, avoid cleaning dead angles, and achieve no residue. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: relatively movable upper valve body and lower valve body, a filling cavi...
