[0002] The MVR evaporator automatic control system was developed to meet the control requirements of the MVR evaporation system. It uses Siemens S7-300 PLC and WINCC to automatically control the evaporation process. MVR evaporator technology has become increasingly mature in China. Compared with traditional evaporators, MVR evaporators offer many advantages, leading to their increasing application in China. When using an MVR system, a V-shaped ball valve must be installed.

During installation, the V-mouth of the V-type ball valve will not face downward, thereby reducing the convenience of installing the V-type ball valve. Therefore, we propose an installation structure for the V-type ball valve in the MVR system. Utility Model Content
