Valve apparatus, arrangement with valve apparatus and method for operating arrangement

Abstract

The invention relates to a valve apparatus having a housing (100), which housing has a first port (102), which can be connected to a tank (200), and a second port (106), having a closing element (110) which is provided in the housing and which can be placed into an open position, in which a fluid connection is produced between the first port and second port, and which can be placed into a closed position, in which the first and second ports are separated from one another in fluid-tight fashion, having a first (120) and a second (130) seal arrangement between closing element and housing, wherein the first and the second seal arrangement (120, 130) are spaced apart from one another and wherein each seal arrangement interacts with a corresponding seat (126, 136). To create a valve device for the aseptic transport of filling material, it is proposed that a chamber (140) be provided which, in the closed position, is delimited by the seal arrangements, the closing element and the housing, and that a reservoir (142) is provided which can be connected to the chamber and which serves to accommodate a bactericidal fluid, and that the chamber (140) and the reservoir (142) are adapted to form a germ barrier that is created in the closed position with the bactericidal fluid. The invention also relates to an arrangement having a valve apparatus of said type and to a method for operating an arrangement.

Description

technical field [0001] The invention relates to a valve device according to the preamble of claim 1 , an arrangement with a valve device according to claim 10 and a device for operating a device with a valve device according to claim 14 . The method to configure the structure. Background technique [0002] For many foods, the origin and marketing of primary products are separated by great distances. For example fruit is harvested in South America and further processed into a liquid food material which has to be transported all the way to Europe. Here, the transport takes place, for example, in box containers. Such a box container has a frame structure in which the container is fixed. The box container can then be transported aboard a container ship and transloaded at the port of destination onto a ground-connected means of transport and transported on rail and road. Here, a frame structure is necessary for the loading and reloading process. A valve device is provided on...

Problems solved by technology

[0006] The consequence is that until now some food materials could not be transported over long distances by means of such box containers, because bacterial contamination could not be prevented despite careful handling and handling with sterilizing fluids, for example with hot steam
