DESCRIPTION OF THE INVENTION

The invention relates to water heating systems with forced coolant circulation in autonomous heating and hot water supply systems and can be used to heat internal volumes of buildings.

A hot-water steel boiler is known, comprising a housing provided with a furnace, made with double walls, a bottom and a lid with insulation forming a water volume, equipped with a water inlet and a water tap, a connection with a chimney, a frame for fastening the gas burner and a water heater, Installed in the furnace, the water heater is provided with self-contained connections to the heating system and is mounted on brackets, the water heater being made in the form of sections fastened together by their opposite ends by means of transition nozzles and arranged by their heat exchange surfaces with slopes at angles of 2-3 ^° for two Side. The water heater is made in the form of sections fastened together by their opposite ends by means of transition nozzles with the formation of a space between the heat exchange surfaces of the sections and displaced relative to each other to the opposite walls of the body to form gas passages across sections with oppositely changing directions (see RF patent N 2113660, F 24 H 1/00).

The disadvantage of this boiler is the complexity of the design, low efficiency of the system, high cost of heat.

A fire tube steam boiler containing a furnace with a burner device located in the lower part of the boiler is known, a vertical bundle of flame tubes installed inside the outer tube, a branch pipe of direct and reverse water, an expansion tank (see Household hot-water fire-fighting boilers of the type MMZ - 1,0 / 8 , MMZ - 0,7 / 8, AGV -120, Moscow Machine Building Plant, 1995).

The disadvantage of this boiler is the high cost of heat energy production, the use of electric pumps that serve the boiler and the heating system.

The closest to the technical entity and accepted authors for the prototype is a heating system consisting of a hot-water boiler with a supply and return lines of the heating system, a circulating boiler pump with a throttle valve, a safety valve, a thermostat (see OSBY OPEX Sweden, 1998).

The disadvantage of this heating system is the complexity of the design, the high cost of heat.

The aim of the proposed invention is to ensure the boiler's thermal regime during launches and connection to the heating system, simplify the design, reduce the cost of heat.

The goal is achieved by the fact that in the heating system with forced circulation of the heat medium containing the boiler, the return and return lines of the heating system, the circulation pump, an automatic thermostatic three-way valve is also installed, consisting of a cylindrical body with three nozzles, and inside the body there is a thermostat with a bushing , A removable cover and a gasket, the two nozzles being installed in the cylindrical parts of the housing at different heights and the third bypassing at the bottom of the housing and connected to the return line of the heating system, the branch pipe installed in the lower part of the cylindrical housing being connected to a branch pipe, Installed in the upper part, and with the flow and return lines of the heating system by means of a thermostat.

In Fig. 1 gives the general view of the heating system with forced circulation of the coolant.

In Fig. 2 is given an automatic thermostatic three-way valve, cut.

The heating system with forced circulation of the heating medium contains a boiler 1 connected to the supply 2 and back 3 lines of the heating system, a circulation pump 4, an automatic thermostatic three-way valve 5 consisting of a cylindrical body 6 with three branch pipes 7, 8, 9, The thermostat 10 by means of a bushing 11, a removable cover 12 and a gasket 13, the branch pipes 7 and 9 being installed in the cylindrical parts of the housing 6 at different heights, and the branch pipe 8 - bypass - at the bottom of the housing 6 and connected to the return 3 of the heating system, This branch pipe 7 installed in the lower part of the cylindrical body 6 is connected to the branch pipe 9 installed in the upper part and to the supply 2 and return 3 lines of the heating system by the thermostat 10.

The heating system with forced circulation of the heat carrier works as follows.

When the heating system starts, boiler 1 starts, after heating the boiler 1 above 60 ^° C, the circulation pump 4 starts. During the start-up of the boiler 1, the thermostat 10 installed with the bushing 11, the removable cover 12 and the gasket 13, is in an inoperative state, the supply of cold water Through the pipe 9 into the heating system is closed. All water is supplied by the circulation pump 4 through the bypass 8 to the return line 3, bypassing the heating system. As the boiler 1 warms up to 80 ^° C (the setting temperature of the start-up of the thermostat 10), a part of the heated water starts to flow into the heating system through the supply line 2 through the branch pipe 9 installed in the upper part of the cylindrical housing 6, and the part continues to enter the return 3 Line through the pipe 8, maintaining the necessary water temperature at the entrance to the boiler 1. When the heating system is fully heated, the thermostat 10 closes the pipes 7, 8 completely and hot water enters the heating system.

The proposed invention in comparison with the prototype and other known technical solutions has the following advantages:

- the thermal mode of the boiler is provided during start-ups and connection to the heating system;

- simplification of design;

- cheaper cost of heat energy;

- Improved safety of fuel combustion;

- Boiler efficiency increase by 15-20%;

- Improvement of the ecology of the environment.

CLAIM

The heating system with forced circulation of the heating medium, which contains the boiler, the supply and return lines of the heating system, the circulating pump, characterized in that it is additionally equipped with an automatic thermostatic three-way valve consisting of a cylindrical body with three nozzles, and inside the body there is a thermostat with a sleeve, Covers and gaskets, the two nozzles being installed in the cylindrical parts of the housing at different heights, and the third - bypass - in the bottom of the housing and connected to the reverse line of the heating system, with the branch pipe installed in the lower part of the cylindrical housing connected to a branch pipe installed in The upper part, and with the supply and return lines of the heating system by means of a thermostat.
