Description

{The equipment of discharging condensation-water for preventing freeze}

The present invention relates to a heating device of a building, and in detail, it is installed at the outlet side of a device or a device using steam and hot water to automatically drain condensate remaining in the heating device to increase the efficiency of the heating device and prevent freezing. And anti-freeze condensate drainage.

For people living in confined spaces, such as offices in large buildings, it is very important to live in the right climatic conditions. To this end, homes and offices maintain air conditioning in the summer and heating in the winter. Such well-known constant temperature facilities include a wide variety of heat exchangers such as air conditioners and air conditioners such as air conditioners.

Representative examples of the equipment for heating, such as a hot air blower is mainly used for electricity, and in addition to the heating device for passing the heated high temperature hot water as shown in FIG.

1 is a view for explaining a conventional heating apparatus. As shown in the drawing, the conventional heating device 10 has an inlet pipe 10x for introducing high temperature hot water to the side surface and a drain pipe 10y for draining the condensed water remaining inside the heating device 10. .

Hot water of high temperature flows into the inlet pipe 10x, and the heating device 10 is designed to heat the indoor air while passing in one direction. In addition, the inlet pipe 10x is provided with a valve 101 for opening and closing the inflow of hot water. The high temperature hot water introduced into the heating device 10 warms cold indoor air and turns into condensed water, ie, low temperature water, whose temperature is much lowered and is drained through the drain pipe 10y.

The valve 151 is also connected to the drain pipe 10y on the outlet side. When the hot water is introduced into the inlet pipe 10x, the valve 151 of the outlet side drain pipe is used to reintroduce the condensed hot water that has passed through the heating device 10 and reintroduce the inlet pipe 10x.

When condensate accumulates inside the heating device 10, the condensate water may reduce the efficiency of the heating device 10 and largely cause the heating device 10 to fail. In addition, when the operation of the heating device 10 is stopped for a long time, the condensation water remaining inside the heating device 10 freezes, causing problems in freezing pipes through which hot water of ordinary temperature should pass.

In addition, as shown in the drawing, the valve 151 of the drain pipe 10y is opened to drain the remaining condensate, and the condensate is drained therein. There is an inconvenience to drain the condensate inside by opening and closing manually.

Therefore, an object of the present invention for solving the above problems, installed on the outlet side of the device or apparatus using steam and hot water automatically detects the pressure inside the heating device to automatically drain the condensate remaining in the heating device The present invention provides a technique for preventing freezing condensate drainage, which can increase heating efficiency and prevent freezing.

In addition, this requires a configuration for smoothly maintaining the overall flow, including the process and characteristics of high temperature hot water and steam used for heating facilities.

As shown in the perspective view shown in the right side of Fig. 3, the inner coupling frame 203 has an outer circumferential surface protruding so that the frame opening 203a can be caught inside the apparatus body 201. In the mold opening 203a, a rubber packing 203b is installed in order to efficiently close the freeze-proof condensate drain 20. The lower end of the mold opening 203a is formed with a thread 203c for coupling with the apparatus body 201, and a plurality of drain holes 203d are formed to drain the condensate. A support protrusion 203e is formed therein, and a fixing protrusion 203f is formed around the spring 207 to support the movement and movement of the opening / closing rod 205.
