PRESSURE RELIEF MODULE Russian patent published in 2018 - IPC B05B12/08 B05B9/04 

FIELD: machine building.

SUBSTANCE: invention relates to a pressure relief module and a paint circulating system including a pressure relief module. More particularly, relates to a pressure relief valve for a fluid circulating system and to a paint circulating system comprising a pressurised paint supply pipeline, a tank return pipeline and a pressure relief valve. Paint circulation system includes a paint supply line under pressure, a paint return line to the reservoir and a pressure relief module. Pressure relief module for the paint circulation system comprises an inlet port of the feed stream to produce a pressurized flow of ink, an outlet port of the feed stream for supplying the ink stream, a supply flow inlet port configured to receive a pressurized supply of paint, and a return flow inlet port configured to receive an unpressurized return paint flow, a first flow chamber connecting the supply flow inlet port to the supply flow outlet port, A second flow chamber connecting the return flow inlet port to the return flow outlet port, an opening connecting the first flow chamber with the second flow chamber, and a gate member biased against the opening to block it, wherein the shutter element is configured to move it in response to a pressure increase in the first flow chamber of a predetermined pressure relief value for displacing the shutter member with opening the opening to allow the ink flow from the first flow chamber to the second flow chamber, wherein the pressure relief module further comprises a housing, a first flow chamber and a second flow chamber forming flow channels in the body and share a common separating wall, and wherein the opening is disposed in a common separation wall.

EFFECT: invention provides an improved paint circulation system with a pressure relief module.
