Description
This case is divisional application, and parent application number is 201610372262X, the applying date 20160531.
Technical field
The present invention relates to a kind of filter device, especially a kind of adjustable filter.
Background technique
Filter is indispensable a kind of device on pumped (conveying) medium pipeline, is typically mounted on pressure reducing valve, relief valve, Ding Shui
Position valve, the import end equipment of the square other equipment of work filter.Filter is by cylinder, stainless steel filtering net, blowdown part, transmission device
And electrical control division is grouped as.After the filter cylinder of strainer screen, impurity is blocked water to be processed, when needing to clean
When, as long as dismountable filter cylinder is taken out, reloaded after processing, therefore, working service is extremely convenient.Filter work
When, water to be filtered is flowed through strainer, is entered the needed pipeline progress process cycles of user by exporting, in water by entering when the mouth of a river
Particle acrobatics be trapped within interior.So continuous circulation, the particle being retained down is more and more, and the rate of filtration is got over
Come slower, and the sewage of import still continuously enters, and filter opening can be smaller and smaller, and pressure is thus generated between import and export
Difference, when magnanimous difference reaches setting value, electric signal is transmitted to controller by differential pressure transmitter, and it is logical that control system starts drive motor
It crosses transmission component band moving axis to rotate, while sewage draining exit is opened, and is discharged by sewage draining exit, after filter gauze cleaning, pressure difference is dropped to most
Small value, system return to inceptive filtering shape, and system operates normally.
