Description

Double pressure taking PLAN52 system with root valve Technical Field The utility model relates to the field of mechanical sealing, in particular to a double pressure taking PLAN52 system with a root valve. Background In industrial production, a mechanical seal is widely used as an important sealing device in rotary devices such as pumps, compressors, reaction kettles and the like, and is mainly used for preventing medium leakage and ensuring the normal operation of the devices and the safety of the environment, and at present, a traditional mechanical seal flushing system (such as PLAN 52) has been widely adopted, and the main function of the mechanical seal flushing system is to keep lubrication, cooling and pressure stability of a sealing element through a buffer solution circulating system, and in the PLAN52 system, buffer solution circulates between sealing rings and ensure the normal flow of the buffer solution through pressure control so as to prevent leakage, however, the traditional PLAN52 system still has the following defects: The traditional PLAN52 system is simpler in pressure monitoring aspect, generally has only one pressure taking point, the pressure change of the buffer solution in the whole system cannot be comprehensively reflected, the design limits the accurate adjustment and effective management of the buffer solution system, and because the buffer solution system is not provided with a plurality of pressure taking points, the pressure difference between the buffer solution supply end and the buffer solution return end is difficult to monitor at the same time, the system pressure is unstable, the sealing effect of mechanical sealing is even affected, and the sealing failure or medium leakage can be caused due to the fact that the pressure is too high or too low.
