WATER DRAIN STRUCTURE OF AIR EXHAUSTER FOR A CONDUIT SYSTEM}

The present invention relates to an automatic air discharge device installed in a piping system, and in particular, can not only easily discharge the air due to bubbles generated in the piping system, but also discharge the water discharged due to the failure of the valve does not pollute the surroundings It relates to an automatic air discharge device that can easily discharge the water to the drain.

In general, air bubbles are generated in heating and cooling systems, especially heating piping systems, for various reasons. These bubbles reduce the heat exchange efficiency of the heater and interfere with the heating water flowing back into the piping, which prevents the circulation of the heating water. Therefore, it is a big problem to lower heating performance, such as a large temperature difference between a heating part side and a heating part side.

In addition, air in the piping system is a cause of corrosion of piping and important parts, a cause of disturbing efficient heat transfer as described above, and a noise of the flow of fluid (cold and hot water). And, there is a problem that affects the operation of the flow meter and the control valve to malfunction.

Therefore, there is a need for an automatic air discharge device that separates the bubbles generated in the piping system from the heating water and exhausts them.

The automatic air discharge device according to the prior art for this purpose has been developed and used to date.

That is, as shown in FIG. 4, the main body 1 includes the upper body 1-1 and the lower body 1-2, which are screwed together, and the float 2 is freely provided in the body 1. It provides an airtight space that can be elevated. The sealed space 1-3 is provided with a reservoir 1-4 for storing the fluid in the piping system up to a predetermined level, and an air chamber 1-5 at the upper side. The lower body 1-2 of the main body 1 is provided with an inlet for connecting a portion of the fluid to the pipe, and the upper body 1-1 extends outwardly at a suitable sidewall thereof and the main body 1 is provided. A tubular exhaust hole (1-6) is formed to be connected to the sealed space in the cavity. And a connecting hole 3-1 connecting the float 2 to the float 2 so as to open the connecting hole 3-1 when the float 2 descends and close when the float 2 rises. 3-2) and the valve body 3 provided with the valve 3-3 hold | maintain airtightly and are combined. In addition, the control valve body 4 for selectively opening and closing the exhaust hole 1-6 is provided outside the exhaust hole 1-6.

Such an automatic air exhaust device is installed at the highest water level in the piping system to achieve the desired exhaust action. That is, bubbles naturally occurring in the fluid in the piping system flow in the piping and flow into the sealed space through the inlet of the main body 1, and the bubbles are introduced through the water surface stored at a predetermined level in the sealed space. As it floats and separates from the fluid, air is continuously filled in the air chamber 1-5 above the sealed space, thereby increasing the partial pressure of air in the air chamber 1-5. When the partial pressure of air in the air chamber 1-5 is increased in this way, the float 2 floating on the water level in the sealed space is lowered along the level lowered by the partial pressure of air, and the float 2 is lowered at this time. While pulling down the valve 3-3, the connecting hole 3-1 is opened. In this operation, the air collected in the air chamber 1-5 is exhausted to the outside through the connection hole 3-1 and the exhaust hole 1-6.

The above-described automatic air discharge device according to the prior art had the following problems.

First, when foreign matter adheres to the peripheral area of the connection hole or one surface of the valve contacting one surface of the valve, the water-tightness is deteriorated, so that the water droplets are discharged through the exhaust hole to contaminate the discharge device and its surroundings.

Second, corrosive or impurities in the piping system may be caught between the valve and the inlet of the connection hole, or the corrosive or impurities may float to form a film on the surface of the water, and this film may be generated in the piping system to suppress the rise of air bubbles. As a result, the water level of the storage chamber is increased, and the fluid is discharged to the outside, thereby contaminating the device as well as its surroundings.

In particular, when the automatic air discharge device is installed in the piping of the heating system of the home, as described above, the fluid (heating water) is discharged to contaminate the wooden floor as well as the kitchen sink, there was a problem. .

Therefore, the technical problem to be solved by the present invention is to solve the problems of the prior art described above, in particular, when the fluid in the pipe is discharged with the air or the fluid flows directly when the fluid flows out directly due to a failure of the valve drain pipe immediately It is to provide a means that can be discharged by induction.

In order to solve the above technical problem, the present invention,
