However, the pressure scanning valve will also encounter some problems during use, such as pipeline blockage, sensor drift, thermal error, etc. These problems will affect the accuracy of pressure measurement and the life of the equipment. In order to solve these problems, the pressure scan valve usually needs to be cleaned and calibrated regularly, and the purge function is a method used to clean the internal pipeline of the pressure scan valve, which can effectively prevent pipeline blockage and ensure the accuracy of pressure measurement and equipment life.
The purge function of the pressure scan valve is used as follows:
In the control software of the pressure scanning valve, select the blowing state and set the blowing parameters, such as blowing time, blowing interval, blowing pressure, etc.
Insert the purge air source into the purge port of the pressure scanning valve, open the purge valve, and start purging.
During the purging process, observe the display screen of the pressure scanning valve to check the pressure value of each channel. If there is any abnormality, the purging can be stopped to check whether there is air leakage or blockage in the pipeline.
After the purge is completed, close the purge valve, disconnect the purge gas source, switch back to the collection state, and continue the pressure measurement.
The purge function of the pressure scan valve is a simple and effective maintenance method, which can improve the performance and stability of the pressure scan valve, prolong its service life, and provide reliable data support for pressure measurement. The purge function of the pressure scanning valve can remove dust, moisture, grease and other impurities in the pipeline, prevent the pipeline from being blocked and the pipeline is unblocked. Eliminate the differential pressure caused by the reverse flow, do not affect the accuracy of pressure measurement, and avoid damage to the sensor due to excessive differential pressure. Blowing is carried out online, and there is no need to disassemble or replace the pipeline, saving time and manpower. Set purging parameters according to needs, such as purging time, purging interval, purging pressure, etc., to achieve automation and intelligence of purging.
