Definitions

• An in-flow mixing unit is a device that regulates the temperature of liquids in heating systems in private and industrial premises. It can also be used in any other systems to change and control the characteristics of liquids.
• the invention refers to the field of power engineering and can be used in water heating systems for private and industrial premises and other technological needs.
• a conventional hydraulic separator for heating systems (hydraulic separator, bottle, hydrodynamic thermal separator) is known, which is used in heating systems to equalise temperatures and pressures in the system.
• a mixing unit (three-way valve or other technical device) is known, in which the heat carrier flows are redistributed to achieve certain temperature parameters, used in the installation of underfloor heating in private houses.
• the present invention combines a hydraulic separator and a mixing unit in a single housing.
• the in-flow mixing unit for heating systems combines a hydraulic separator and a mixing unit and consists of a housing with a heat carrier fluid inlet pipe from the heat source and a heat carrier fluid return pipe to the heat source, through which the heat carrier fluid moves in the housing, and two pipes on the opposite side of the housing, connected to each other by a jumper, thus forming an H-shaped structure with four openings, where two openings of this device are located inside the housing with a constant flow of heat carrier fluid, and the other two are outside.
• the jumper can be located either outside or inside the housing with the heat carrier fluid and the valve can be positioned both outside and inside the housing, thus the two outlets on the outside form the inlet and outlet of the heat carrier fluid with the required characteristics, where the heat carrier fluid is moved by a circulation pump.
• the temperature is regulated by controlled mixing of the fluid from the housing and jumper (return from the regulated circuit) by means of a thermal head or other mechanism that moves the valve stem, which operates continuously in an opening-closing mode, changing the mixing ratio of the heat carrier fluid from the housing and the return circuit to achieve the required temperature in the circuit.
• the heating system has different temperatures for radiator heating and underfloor heating. Lowering the cost of the system without losing reliability and performance.
• FIG. 1 A schematic diagram of the invention is shown in Fig. 1 in section A-A, where the arrows indicate the directions of heat carrier fluid flow.
• Housing 1 heat carrier fluid inlet branch pipes from the heat source (supply) 2 and heat carrier fluid return branch pipe to the heat source (return) 3 are also shown, thus heat carrier fluid moves (flows) in the housing.
• the flow mixing unit is a device consisting of two heat carrier fluid supply branch pipes 4 to the system where the temperature needs to be lowered and controlled (underfloor heating), return branch pipe from the system 5, movable stem 6, valve plate 7 and a jumper between the branch pipes 8.
• the jumper 8 has a smaller diameter than branch pipes 4 and 5, thus forming an H-shape with 4 holes from pipes 4, 5 and 8, where two holes of this device are located inside the housing 1 with a constant flow of heat carrier, the other two are outside, and the jumper 8 itself can be located either outside or inside the housing with the heat carrier, thus the two outlets 4 and 5 outside form the inlet and outlet of the heat carrier with the necessary characteristics, where the heat carrier is moved by a circulation pump, and the temperature is regulated by controlled mixing of the liquid from the housing 1 and jumper 8 (return from the regulated circuit) by means of a thermal head or other mechanism, which moves the stem 6 of valve 7, which constantly operates in an opening-closing mode, changing the mixing ratio of the heat carrier fluid from the housing 1 and return 5 of the circuit to achieve the required temperature in the circuit after the hydraulic separator in the hydraulic separator directly.
• valve plate 7 instead of the valve plate 7, another design 9 ( Fig. 2 ) is possible, using the stroke of the stem 6 to ensure complete closure of the jumper 8 and opening of the branch pipe 5 inside the flow of the hydraulic separator housing 1, thereby achieving complete redistribution of the flows.
• the invention is placed in a container 1 with a circular or square cross-section, in which the heat carrier flows.
• Various pipes for an air vent and a drain valve may also be provided on the housing with the invention installed in it, depending on the configuration. Let's consider an example of a simplified hydraulic separator without drain pipes and air vent ( Fig.
• Brass, steel with or without anti-corrosion coating, or stainless steel used in heating systems is the material used to manufacture the invention ( Fig. 1 ).
• the invention is used in heating systems for private and industrial premises and any other systems for changing and controlling the characteristics of liquids.
