[0002] Bathroom hot water is usually supplied by tap water, which is heated by a hot water heater and sent to the bathroom through a pipeline. The remaining hot water returns to the pump inlet, is pressurized by a booster pump, and is sent to the tap water pipeline and enters the hot water heater together.

[0003] The heat source of the hot water heater usually uses 1.0MPA steam to enter the tube bundle inside the heater through a manual valve or a traditional electric temperature control valve. The condensed water generated by heating the tap water enters the condensate water network.

[0004] The heating control valve in the traditional steam heater room is easily damaged due to long-term exposure to high temperature; at the same time, the traditional control may have relatively poor stability, and there is a risk of scalding people due to the hot water fluctuating between hot and cold when taking a bath.

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] like Figure 1The temperature control process system of the bathroom hot water heater shown comprises: a steam heater 1, wherein the bottom of one end of the steam heater 1 is connected to a water inlet pipeline 2, the top of the steam heater 1 is connected to a bathroom user point 4 through a water outlet pipeline 3, the water outlet pipeline 3 is connected to a hot water circulation pipeline 5, a hot water circulation pump 6 is arranged on the hot water circulation pipeline 5, the hot water circulation pipeline 5 passes through the hot water circulation pump 6 and is connected to the water inlet pipeline 2 at the bottom of the steam heater 1; the steam heater 1 is connected to a 1.0MPA steam pipeline 7, the 1.0MPA steam pipeline 7 is provided with an instrument air regulating valve group 8, and the 1.0MPA steam pipeline 7 is also provided with a steam inlet valve 9 near the steam heater 1;

[0024] The water inlet pipeline 2 is a tap water pipeline, and a steam heater inlet valve 10 and a one-way valve 11 are sequentially arranged on the water inlet pipeline 2 from the water inlet direction, and the steam heater inlet valve 10 is a manual valve;

[0025] Furthermore, a thermometer 12 and a pressure gauge 13 are respectively provided above the steam heater 1, and a safety valve 14 is also provided on the steam heater 1 near the pressure gauge 13 through a pipeline;

[0026] Furthermore, the bathroom user point 4 is a plurality of pipeline joints connected in parallel with the water outlet pipeline 3 of the steam heater 1, and valves are provided on the respective pipelines of the bathroom user point 4;

[0027] Furthermore, the hot water circulation pipeline 5 is provided with a hot water circulation pump inlet valve 15, a hot water circulation pump 6, a hot water circulation pump outlet check valve 16, and a hot water circulation pump outlet valve 17 in sequence;

[0028] Furthermore, a condensation pipeline 18 is provided at the bottom of one side of the steam heater 1, and a condensate outlet valve 19 is provided on the condensation pipeline 18. The condensate generated in the steam heater 1 passes through the condensate outlet valve 19 and the condensate pipeline 18 to the condensate network;

[0029] Furthermore, the instrument air regulating valve group 8 on the 1.0MPA steam pipeline 7 includes: a regulating valve and hand valves before and after the regulating valve, and a bypass line is also set before and after the hand valve through the pipeline; the opening of the regulating valve is controlled by the temperature on the steam heater 1 to achieve stable control of the hot water temperature in the bathroom;

[0031] Now we need to add a regulating valve and front and rear hand valves to the 1.0MPA steam pipeline 7, and realize the stable control of the bathroom hot water temperature by controlling the opening of the regulating valve on the steam heater 1. First of all, it saves the trouble of frequent adjustment of the hand valve, and the hot water temperature is unstable. In addition, some traditional processes are often manually adjusted because the temperature control electronic components of the steam heater room are easily damaged in a high temperature environment for a long time.

[0032] Adding a pneumatic regulating valve to the outdoor steam pipeline can more smoothly control the temperature of the steam heating tank, ensure the stability of hot water in the bathroom, and prevent people from being scalded by the hot water during bathing.

[0033] The tap water enters the steam heater 1 through the tap water pipeline, the steam heater inlet valve 11 and the one-way valve 12. After being heated by steam in the heater 1, the tap water is sent to the bathroom user point 4 through the water outlet pipeline 3 for hot water supply; part of the return water returns to the hot water circulation pipeline 5, passes through the hot water circulation pump inlet valve 15 to reach the hot water circulation pump 6, and after being pressurized by the hot water circulation pump 6, comes out from the hot water circulation pump outlet one-way valve 16 and the hot water circulation pump outlet valve 17 and is sent to the tap water pipeline to enter the steam heater 1 for heating and circulation.

[0034] The heat source of the steam heater 1 comes from the 1.0MPA steam pipeline 7. The steam enters the heater tube bundle through the 1.0MPA steam pipeline 7 and the steam inlet valve 9 to heat the tap water. The condensed water produced by condensation comes out through the condensate outlet valve 19 and the condensate pipeline 18 to the condensate network.
