A hot filling valve

Abstract

The invention discloses a hot filling valve. The hot filling valve comprises a valve seat, a valve element, a material cylinder, an outer sliding sleeve and a sealing base, wherein the valve seat is arranged on a supporting rotating disk in a vertical lifting manner and is driven by a valve seat lifting driving mechanism, a central gas return hole which penetrates through the whole valve element axially and is communicated with a gas return pipe is formed in the valve element, a valve element sleeve pipe is arranged outside the valve element in a sheathing manner, a reflux gap is left between the valve element sleeve pipe and the valve element, the outer sliding sleeve is arranged on the valve seat in a lifting manner, a filling channel is arranged between the outer sliding sleeve and the valve element sleeve, the reflux gap is communicated with the filling channel, the sealing base is fixed on the outer sliding sleeve, the material cylinder is communicated with a filling liquid inlet by a filling branched pipe, and a reflux opening is communicated with a reflux container by a control valve. According to the hot filling valve, a gas return channel is completely separated from a reflux channel, the reflux quantity is controllable, the defects such as unstable production capacity, and large liquid level precision fluctuation caused by a phenomenon that gas and liquid are mixed in the same channel are avoided, and the nutrition of beverage cannot be lost.

Description

technical field [0001] The invention relates to a filling valve, in particular to a hot filling valve used for filling beverages. Background technique [0002] Some beverages contain sugar, tea polyphenols and other viscous components. During the normal temperature filling process, the viscous components are easy to separate out and stick to the pipes and filling valves, which are difficult to clean and cause pollution. Therefore, currently, the filling of such beverages is generally Hot filling equipment is used, and the hot filling valve is one of the main components. [0003] Current hot filling valves include mechanical filling valves and electronic filling valves. The present invention is directed at mechanical filling valves. The mechanical filling valves commonly used at present have the following defects: 1. The reflux channel is located in the same channel, and the gas-liquid mixture causes unstable production capacity of the filling machine and large fluctuations ...

Problems solved by technology

[0003] Current hot filling valves include mechanical filling valves and electronic filling valves. The present invention is aimed at mechanical filling valves. The mechanical filling valves commonly used at present have the following defects: 1. The air return passage and the electronic filling valve The backflow channel is located in the same channel, and the gas-liquid mixture causes unstable production capacity of the filling machine and large fluctuations in liquid level accuracy; 2. The return flow rate cannot be adjusted arbitrarily, and the material is repeatedly heated and sterilized, thereby reducing the nutritional function of the liquid food and affecting the taste of the material; 3 .It is difficult to clean the inside of the valve body, and the hygienic index is low
