DIFFERENTIAL PRESSURE CONTROL VALVE WITH WASHING Russian patent published in 2017 - IPC F16K31/145 F24D19/10 G05D16/06 

FIELD: machine engineering.

SUBSTANCE: valve has a valve part comprising: a valve body with flow communication from a fluid inlet to a flow outlet and a valve seat located within said flow communication, a valve cone (3) adapted to change the position for changing the valve opening, defined as the opening between the valve seat and the valve cone, the diaphragm, deflectable by the differential pressure at said diaphragm, and means for communicating the pressure on the antipode complicated sides of the diaphragm; - an adjusting part containing the biasing element and the body of adjuster. Said adjusting part is attached to said valve part; - a spindle having a part located within the adjusting part and a part located inside the valve part and connected to said valve cone. The spindle can be moved to and stored in the washing position, and the valve cone does not interfere with the communication to transfer fluid from the fluid inlet to the fluid outlet or creates at least a limited obstacle.

EFFECT: presence of overlapping function and the washing function that occurs during the installation of the system.
