(54) SLATCHED COMBINED WATER HEATER

one

The invention relates to the field of heat energy in intended for decentralized water heating and hot water supply facilities.

Water heaters 5 for space heating are known, and the production of hot water is the length of domestic water heating systems in which water is heated in two paanHtnibix circuits, and for domestic needs the water is heated by a heating circuit heated by a gas burner flj.

Such devices have a fire chamber with a double-circuit heat exchanger, a circulation pump, a main and pilot burner, 15 ki, a gas unit, a two-way three-position hydraulic valve, and an electronic control unit.

However, these devices are not reliable and safe in operation.

A water-rejuvenator is known, which contains a heating system, a circulating pump and a control system with sensors, a membrane water block and a flow switch 2j, ..25

However, mi is also not reliable enough.

The aim of the invention is to increase the operational reliability and safety in the operation of a gas combined water heater.

This is achieved by the fact that the switch is made in the form of a two-armed lever with a single valve on one arm and doubled on the other, and the WATER block is equipped with two diaphragms connected by a stem and a partition between them, having a hole for the stem connected to the control system.

The drawing shows a schematic diagram of the proposed water heater.

It contains a single-circuit heat exchanger 1, a heating system consisting of a main burner 2 and a pilot burner 3, a filling pump 4 with an inlet 5 and 6 outlets 6, a control system 7 with a slam-shut valve 8 and a valve 9, contact 10, button 11, an electromagnet 12. The control system contains a TajOKe sensor 13 by the presence of draft in the chimney sensor. 14 for overheating of the heat exchanger, sensor 15 for the presence of the ignition burner sensor, sensor 16 for the heat, water leaving the apparatus, sensor 17 for the temperature of the air of the heated room, two-stage valve 18, the water heater has a diaphragm embedded block 19 consisting The membranes 20 and 21 of the pins 22 and 23, the springs 24, the device 25 and the microswitch 26, and the flow switch, consisting of valves 27 and 28, which open the water inlet and outlet of the heating system, and the valve 29, regulate the flow of water for hot water supply. Combustion products are discharged. Through a drainage device 30, Nozzle 31 serves to supply water for hot water supply, 32 - toggle knob: flow controller. In the heating system, a valve 33 and a Venturi tube 34 are located on the supply water line. A high pressure impulse is transmitted by the channel | 35 to the cavity of the high pressure 36, and a low pressure impulse is transmitted through the channel 37 to the cavity 38 of not under pressure. Boa under pressure p6, the channel 39 enters the cavity 40. The gas combined water heater works in the following way. Pressing the button 11 of the shut-off valve 8 opens the access of gas through the gas flow regulator to the pilot burner 3, contacts 10 are closed at the same time (power supply to the electronic control unit) and the gas-air mixture in the pilot burner is ignited with an electric spark discharge lamp. Gas is supplied to the main burner when valves 8, 9 and two-stage valve 18 are opened. The operation of valves 8 and 9 is monitored through an electromagnet 12 by sensors 13, 14 and 15. The operation of two-stage valve 18 is monitored by sensors 16, 17 and by a flexible water unit 19. When the knob 32 switches the flow switch to the hot water position, the hot water supply valve 29 to the water supply opens, valve 27 and 28 blocks the inlet and outlet water of the heating system. After this, the valve Zo installed on the inlet water pipe is opened, and the water passes through the pipeline through the tube Ven., Tour 34 into the heat exchanger 1. The presence of the water flow in the device is controlled by a membrane j with a water block 19, the housing of which is separate; n membranes 20 and 21 into three cavities under water pressure. A high pressure pulse through channel 35 is supplied to a high pressure cavity 36, and a low-pressure g / pulse is fed through channel 37 to a low pressure cavity 38. The impact 20 acts through the stem 22 on the second membrane 21, which is exposed to the gun 23 on the other hand. The membrane 21 mixes the rod. 23, which is located in a waterless cavity and in turn howls device 5, ensuring the smooth closure of the ontransmitter microswitch 26, imparting an electrical impulse to the gas unit. In the absence of water flow Pressure C cavity x. 36 and 38 are aligned and both membranes under the influence of the spring 24 return to their original position, break the contacts of the microswitch and stop the gas supply to the main burner 2. In the position of heating the knob 32 of the flow switch, valves 27 and 28 open the inlet and outlet of the heating system water, and the valve 29 closes the water outlet to hot supply, valve 33 is closed. At the same time, the circulation pump 4 with the electric drive and the sensor 17 of the tegus of the air of the heated room automatically turn on. Water is heated in the same heat exchanger, water is circulated in the heating system through the outlet 6 and the inlet 5, the control of the water flow is carried out by the membrane water unit 19. The pressure of water through the channel 3 9 is transferred to the cavity 40 and acts on the membrane 21, the water unit starts to work. Claims of the invention A gas combined water heater mainly for decentralized heating and hot water supply, comprising a heating system, a circulating pump and a control system with sensors, a membrane water unit and a flow switch, characterized in that, in order to increase operational reliability and safety, the switch made in the form of a two-armed lever with a single valve on one shoulder and doubled on the other, and the water block of sleep: it has two membranes, one behind the other, and The partition between them, having a hole for the rod connected to the control system.
