METHOD FOR DETERMINING VALUES OF HINGE MOMENT COMPONENTS AND BENCH FLOW REGULATOR TO PROVIDE IT Russian patent published in 2024 - IPC F16K5/10 F16K5/12 G01M15/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the designs of flow regulators. A method is proposed for determining the values of the components of the hinge moment in flow regulators, based on air tests of flow regulators, which consists in the fact that air tests are carried out with the flow opening of the flow regulator closed, for which the flow pipe is hermetically sealed, air is supplied inside the unit under operating pressure and the component is measured hinge moment, equal to the friction moment in the seals over the entire range of rotation angles when moving towards the opening of the flow hole of the flow regulator; then the flow pipe is opened and, under the same conditions, the total hinge moment is measured, after which, at the same angular position, the gas-dynamic component of the hinge moment is determined using the formula. A bench valve design for implementing the method is also proposed.

EFFECT: guaranteed thermal gap is made between the parts that regulate the flow hole.
