An elastic force is provided to the valve seat 85 to close. On the other hand, when the valve spring 89 is compressed, the pitch of the valve spring 89 becomes small, so that the valve spring 89 flows in with water through the stem receiving hole 93 of the coupler 91. It acts as a crusher of air having a particle size, ie as an air separator. Here, the coil spring is disclosed as the valve spring 89 in this embodiment.

By such a configuration, when the multi-function air vent 1 according to the present invention is connected to a pipe (not shown), the operation of the multi-function air vent 1 will be described.

As shown in FIG. 3, the stem receiving hole of the coupler 91 connected to the pipe in the state in which the strainer body 53 of the strainer 50 presses the valve seat 85 and the valve spring 89 is compressed. Water flowing along the pipe through the 93 is introduced into the sheet storage chamber (77). At this time, as the pitch of the valve spring 89 decreases, the valve spring 89 chops the air having a large particle size contained in the water flowing through the stem receiving hole 93 of the coupler 91. Collateral plays a role.

Water introduced into the sheet accommodation chamber 77 passes through a plurality of filtration holes formed in the strainer body 53, and flows into the inlet 13 of the body 10 through the guide hole 57.

If air is contained in the water flowing into the chamber 17 of the body 10, the floating body 41 is lowered along the rod 43, and then the lowering is prevented by the stopper 49, and the chamber continues. When air is increased in the water introduced into the (17), as shown in Figure 4 buoyancy acts on the floating body 41, the rod 43 with the floating body 41 is lowered.

At this time, as the floating body 41 and the rod 43 descend, the disk spring 47 is compressed, so that the disk 45 closing the air outlet 15 is spaced apart from the air outlet 15. The outlet 15 is opened.

Thus, the air introduced into the body 10 is discharged to the outside through the air discharge port 23 of the cover 21 via the air discharge port (15).

Then, when the water fills the chamber 17 of the body 10, the floating body 41 rises, thereby returning the disk 45 to its original position while tensioning the spring 47 for the disk, thereby causing the air outlet. (15) is closed.

As a result, the multi-function air vent 1 according to the present invention not only automatically discharges air generated naturally in the pipe, but also filters foreign substances introduced into the body 10 and simultaneously collects particles of air generated in the pipe. It can be made small to be discharged to the outside through the air outlet (15).

Next, the process of cleaning the multi-function air vent 1 according to the present invention will be described.

As shown in FIG. 3 or FIG. 4, in the process of using the multifunctional air vent 1 according to the present invention, that is, the valve spring 89 is compressed and the valve seat 85 passes through the through hole 81. In the open state, as shown in FIG. 5, when the body 10 and the valve housing 71 are spaced apart from each other, the valve seat 85 is raised by the elastic force of the valve spring 89 so that the valve housing 71 is opened. To close the through hole (81).

As the through hole 81 is closed, water flowing through the pipe does not flow into the body 10.

As a result, the multifunctional air vent 1 according to the present invention can separate the body 10 from the valve housing 71, and thus the body 10 and the strainer 50 can be easily cleaned.

Meanwhile, although water has been described as a fluid applied to the multifunctional air vent in the above-described embodiment, the multifunctional air vent according to the present invention may be applied to a fluid such as an oil, a chemical solution, and the like.

In addition, the multi-function air vent according to the present invention can be applied to the piping of boilers, air conditioning systems of houses or factories and large buildings, wastewater treatment of power plants and the like.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to be belong to the claims of the present invention.

As described above, according to the present invention, the inherent function of the air vent for automatically discharging air naturally occurring in the pipe, a valve for blocking the supply of fluid flowing into the air vent, a strainer for removing foreign matters, By adding the function of the air separator to crush the air particles small, it is possible to reduce the installation space, and to provide a multi-functional air vent that can simplify the installation work time.
