The upper and lower flanges 124 and 126 are fastened to each other by upper and lower portions of the main body 120 and fixedly fastened by a connecting rod 127 having a predetermined length. One or both sides of the connecting rod 127 may be fixed by inserting the washer 127b and tightening with a nut 127a.

The upper flange 124 is formed to surround the exhaust port 124a and is provided with a protective cover 128 for preventing foreign matter penetration preventing the outlet port 124a from communicating with the outside. The protective cover 128 is provided with discharge holes 128a having a plurality of holes so that air discharged from the exhaust port 124a can be discharged to the outside. One side of the upper flange 124 is provided with an O-ring (129) to improve the airtightness / watertightness between the impact resistant float 132 when in contact with the impact resistant float 132.

Preferably, the upper and lower flanges 124 and 126 and the body 120 are provided with flange seals 121 at portions where the upper and lower flanges 124 and 126 and the main body 120 come into contact with each other to improve airtightness / watertightness.

Floating means 130 is installed in the receiving space 122 of the main body 120 to be moved up and down in order to increase in the exhaust flow rate inside the water pipe 110 and the inflow of water in order to closely adhere to the exhaust port (124a) side While reducing the inner diameter of the corresponding exhaust holes (132a, 134a) in multiple stages to reduce the exhaust speed.

As a result, the fitting means 130 minimizes the shock when the air is discharged so that there is little damage to the air valve, and when the water in the pipe is drained, the floats 132, 134, and 136 sit down to open the exhaust ports to smooth the air. In addition to being able to be sucked in, it also serves to block the nozzle to prevent leakage.

The fitting means 130 is composed of a shock-proof, air discharge and order float 132, 134, 136 are sequentially raised and lowered in accordance with the increase in the exhaust flow rate or the inflow of water in the water pipe 110.

The anti-shock float 132 is disposed on the top adjacent to the exhaust port 124a of the upper flange 124. The anti-shock float 132 is raised by increasing the exhaust flow rate in the water pipe (110). A predetermined position of the impact preventing float 132 is formed through the upper and lower impact preventing exhaust hole 132a for discharging the internal air in the water pipe 110 is formed. The anti-shock float 132 is preferably formed of a high-density polyethylene (HDPE) material. One side of the anti-shock float 132 is provided with an O-ring 129 to improve the airtightness / watertightness between the air discharge float 134 when in contact with the air discharge float 134.

The air discharge float 134 is disposed under the impact resistant float 132. The air discharge float 134 is in close contact with the impact preventing float 132 as the air pressure increases due to the inflow of water into the receiving space 122. The air discharge float 134 is made of HDPE made of the same material as the anti-shock float 132. The air discharge float 134 is provided with an air discharge exhaust hole 134a that matches the impact prevention exhaust hole 132a, and the air discharge exhaust hole 134a has an inner diameter smaller than that of the impact prevention exhaust hole 132a. A nozzle 134b is provided at a lower portion of the air discharge exhaust hole 134a to discharge the internal air in the water pipe 110.

The order float 136 is disposed below the air discharge float 134. The order float 136 is raised to the air discharge float 134 by the water introduced into the receiving space 122 side. The nozzle seat 136a is detachably provided at a position coinciding with the nozzle 134b on the upper surface of the order float 136. The nozzle sheet 136a is inserted into the seating groove 136a-1 so that the nozzle sheet 136a is pressed by the plate-shaped sheet plate 136b so as not to fall out. The seat plate 136b may be fastened by the order float 136 by the fixing bolt 136c. The nozzle sheet 136a rises at the same time as the order float 136 rises to block the nozzle 134b so that water in the main body 120 does not leak to the outside.

According to the cylindrical float-closed air valve 100 for a water pipe according to the present invention having the above-described configuration, first, a large amount of air in the water pipe 110 is introduced into the air valve 100 through the intake port 126a. The discharged air is discharged through the exhaust port 124a via the receiving space 122 (see arrow ⓐ in FIG. 2).

In addition, when the exhaust flow rate is increased, the anti-shock float 132 is raised to close the bottom of the upper flange 124, thereby blocking the exhaust port 124a. When the anti-shock float 132 blocks the exhaust port 124a, the anti-shock float 132 is provided in the anti-shock float 132 to be forced out through the anti-shock exhaust hole 132a to perform the impact prevention zone. As a result, the exhaust speed in the water pipe 110 is lowered, the air pressure in the air valve 100 is increased, and the access speed of the water flowing into the air valve 100 is lowered (see arrow ⓑ in FIG. 3). .

In addition, when the air in the water pipe 110 is discharged and water is introduced into the air valve 100, the air pressure in the air valve 100 is increased to prevent the shock and air discharge floats 132, 134 to the exhaust port 124a side. Is raised. At this time, the air pressure in the air valve 100 does not rise above the water pressure, so that the air comes out through the nozzle 134b (see arrow? In FIG. 4).

Thereafter, when the air in the air valve 100 is discharged to the outside and the order float 136 floats in the water and rises to close the nozzle 134b, the exhaust process is completed. At this time, the order float 136 closes the nozzle 134b so that water does not leak out of the air valve 100 (see FIG. 5).

In this process, the impact prevention, air discharge and order floats 132, 134, and 136 are simultaneously raised to close the exhaust port 124a, and the impact prevention, air discharge, and order floats 132, 134, and 136 are sequentially As it rises, the exhaust port 124a is blocked in multiple stages, so the exhaust speed is reduced and closed. As such, by reducing the exhaust speed, the shock is not generated in the air valve 100.

On the other hand, when the water in the water pipe 110 is drained, the impact prevention, air discharge and the order float 132, 134, 136 descends in the reverse order as described above and the exhaust port 124a is opened to the air constant It is sucked into the tube 110 (see arrow ⓓ of Figure 6).

Although the exemplary embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to such specific embodiments, and the scope obvious to those skilled in the art to which the present invention belongs belongs to the scope of the claims of the present invention.
