COMBINATION OF SHUTOFF VALVE AND CHECK VALVE WITH BUILT-IN MEASUREMENT OF FLOW RATE, PRESSURE AND / OR TEMPERATURE AND WITH PROPERTY OF CHANGE OF CONFIGURATION DURING OPERATION Russian patent published in 2020 - IPC F16K1/30 F16K15/00 F16K27/06 

FIELD: valves.

SUBSTANCE: invention relates to combined valve for HVAC system, which is made with possibility of operation as shut-off valve, check valve and as device for measurement of fluid medium parameters. Combined valve has one or more built-in measuring sensors, check valve and shut-off valve and comprises inlet element having tubular part, which has an inlet portion of the inlet member for receiving a fluid flow and an outlet portion of the inlet member to provide a fluid flow from said inlet and extends along its axis, an inlet flange portion which is connected to the inlet portion inlet portion, extends in outer direction perpendicular to axis of tubular part of inlet element and is intended for connection to inlet pipe, from which fluid medium flow is supplied, and outlet flange part, which is connected to outlet part of inlet element and extends in outer direction with inclination to axis of tubular part of inlet element at an angle, which is 45º. Valve comprises an outlet member having a tubular portion that has an inlet portion of the outlet member for receiving a fluid flow from the inlet member and an outlet portion of the outlet member to provide a fluid outlet from the outlet member and extends along its axis, an outlet flange portion, which is connected to said outlet part of outlet element, is intended for connection to outlet pipe intended for receiving fluid flow from combined valve, and passes in outer direction perpendicular to axis of tubular part of outlet element, and inlet flange part, which is connected to said inlet part of outlet member, extends in outer direction with inclination to axis of said tubular part of outlet member at angle of 45°, and is configured to be connected to the outlet flange portion of the inlet member so as to allow installation of the inlet and outlet valve elements with a straight orientation at angle of 180° relative to the axis of the tubular portion of the inlet member and the axis of the tubular portion of the outlet member, which are parallel to each other, or with angular orientation at angle of 90° relative to axis of tubular part of inlet element and axis of tubular part of outlet element, which are perpendicular to each other, or with angular orientation at intermediate angle of 90º to 180º relative to axis of tubular part of inlet element and axis of tubular part of outlet element, which pass at angle of 90º to 180º relative to each other.

EFFECT: combination of shut-off valve and check valve with built-in sensors for flow rate, pressure and / or temperature measurement provides more compact design, which saves space, for example, by eliminating the need for separate components in the HVAC system, such as separate shut-off valves, check valves, flow meters, pressure sensors and / or thermometers.
