Description

TECHNICAL FIELD

[0001] The utility model relates to a chemical equipment technical field, concretely relates to a pipeline steam sterilization device. BACKGROUND

[0002] In the field of biological medicine or food fermentation, the traditional pipeline steam sterilization needs to install a steam exhaust valve on the valve at the end of the pipeline to ensure the smoothness of the steam so that the whole pipeline or equipment can reach the sterilization temperature without dead angle. As shown in the figure, the existing pipeline steam sterilization device comprises a cut-off valve 13 installed between the left pipeline 11 and the right pipeline 12, a left steam exhaust valve 15 installed on the left outlet pipeline 14 of the cut-off valve 13, and a right steam exhaust valve 17 installed on the right outlet pipeline 16 of the cut-off valve. During the sterilization process, when the left pipeline 11 is sterilized, the cut-off valve 13 is closed, the left steam exhaust valve 15 is opened, and after reaching the sterilization temperature and time, the left steam exhaust valve 15 is closed, and the pipeline is pressure maintained; when the right pipeline 12 is sterilized, the cut-off valve 13 is closed, the right steam exhaust valve 17 is opened, and after reaching the sterilization temperature and time, the right steam exhaust valve 17 is closed, and the pipeline is pressure maintained, and the cut-off valve 13 itself is sterilized by heat conduction of the steam. Figure 1 However, when the pipeline needs to be sterilized from both ends at different times, a cut-off valve 13 needs to be installed on the pipeline, and the cut-off valve 13 is sterilized by steam from both ends during sterilization, and steam exhaust valves (left steam exhaust valve 15 and right steam exhaust valve 17) need to be installed on both sides of the cut-off valve 13, and the steam does not penetrate the cut-off valve itself, but sterilizes the cut-off valve by heat conduction. The cut-off valve on the pipeline is usually a diaphragm valve (or a stop valve). When this valve is closed, a small amount of material is easily pressed between the diaphragm (or valve flap) and the valve body. When the cut-off valve 13 is sterilized in the above-mentioned manner, when there is material between the diaphragm (or valve flap) and the valve body inside the cut-off valve 13, it is difficult to reach the sterilization temperature, and the heat conduction method is difficult to completely sterilize the material, which is prone to cause contamination.

[0003] TECHNICAL SOLUTION The utility model discloses a pipeline steam sterilization device, which can avoid material accumulation in the valve body of the cut-off valve during the sterilization process, thereby ensuring the sterilization temperature, reducing the risk of contamination, and improving the sterilization effect.
