Description

Quick air valve {QUICK AIR-VALVE}

The present invention relates to a rapid air valve, and more particularly, to a rapid air valve for discharging the air present in the fluid pipe, such as water pipes and water pipes out of the water pipe.

In general, air or gas may be generated or introduced into the water pipe or water pipe inherently, and may be introduced into the water pipe for many other reasons. The air thus produced or introduced must be removed from the water pipes frequently because they form pockets in the water pipes that interfere with the smooth flow of the fluid.

Rapid air valves are used for this purpose. The rapid air valve is installed in the water supply pipe and the like to discharge the air in the pipe in a short time, and when the drainage can quickly enter the outside air into the pipe to prevent damage to the pipe.

1 is an exploded perspective view showing a conventional rapid air valve, Figure 2 is a cross-sectional view showing a conventional rapid air valve.

1 and 2, a T-connecting tube 2 is connected to the water supply pipe 1, a dividing side 3 is connected to the T-connecting tube 2, and a rapid air valve on the dividing side 3 is provided. (4) is connected. In general, since air collects at a high point in the water pipe 1, the rapid air valve 4 is generally installed at a relatively high point in the water pipe 1. Here, the T-connecting pipe (2) is mounted to the connection portion of the water supply pipe (1) for connecting the rapid air valve (4) to the water supply pipe (1), the dividing side (3) is the water supply pipe (1) and the rapid air valve ( 4) The water flow is blocked in between to enable the inspection and replacement of the rapid air valve (4).

The rapid air valve 4 includes a body 5 and a flow valve guide 6, the flow valve guide 6 is installed inside the body (5). Passing holes 6a and 6b are formed at upper and lower sides of the flow valve guide 6. The upper end of the flow valve guide 6 is provided so as to extend to the exhaust port of the body 5, and the float valve 7 and the flow valve 8 are sequentially arranged inside the flow valve guide 6.

A flow valve seat 9 is provided for covering the top of the flow valve guide 6 and the body 5, on which the head 17 and the cover 18 are arranged. The head 17 and the cover 18 are fixed to the torso 5 by bolts 19. In the center of the flow valve 8 is mounted a conical valve seat 10, the inner surface of the body 5 and the outer surface of the flow valve guide 6 are spaced apart from each other to form a flow path 16.

The rapid air valve 4 discharges the air present in the water supply pipe 1 before the water flows into the water supply pipe 1 and flows into the water supply pipe 1. Air is rapidly discharged through the water holes 6a and 6b, and as the water begins to fill the valve 4, a float valve 7 having a specific gravity smaller than water floats, and a flow valve located on the float valve 7 8) rises as well.

As the flow valve 8 rises, the flow valve 8 comes into close contact with the flow valve seat 9, and water is no longer discharged out of the rapid air valve 4. At the same time, the float valve 7 drives the valve seat 10 so that water does not flow out. In general, as water passes through the water pipe 1, the water pipe 1 and the inside of the rapid air valve 4 maintain a pressure of about 1 to 10 kgf / cm ² .

On the other hand, when water is drained from the water pipe 1, the float valve 7 and the flow valve 8 is lowered while the water filled in the rapid air valve 4 is discharged, and the water pipe through the rapid air valve (4) The external air flows into (1) quickly, preventing vacuum from occurring in the pipe during drainage, thus preventing water pipe breakage.

The body 5 and the head 17 of the quick air valve 4 are made of cast iron, and the flow valve guide 6 is made of bronze. Therefore, the conventional rapid air valve (4) is easy to rust because it is always in contact with water and air, and once the rusted rapid air valve (4) is connected to a water pipe, etc. This can worsen the quality of water delivered to homes.

In addition, foreign matter may be introduced into the rapid air valve 4 from the outside, and foreign matter suspended in the water pipe 1 may be introduced into the valve 4. In addition, as described above, the valve 4 is corroded in many cases, so that the valve 4 may not function properly. In such a case, the rapid air valve 4 may be separated from the water supply pipe 1 to clean the inside of the valve 4 or to replace the valve 4 itself. In order to separate the valve 4 from the water supply pipe 1, the water flow between the water supply pipe 1 and the valve 4 is cut off using the distillation valve 3, and the valve 4 is removed by removing the flange.

However, the high pressure of about 1 ~ 10kgf / cm ² is formed in the rapid air valve (4) can not be released immediately. Conventionally, in order to separate the valve 4, the cover 18 is removed, and the flow valve 8 is hit with a hammer or the like to separate the flow valve 8 and the head 17 from each other. In this way, the sealing state of the flow valve 8 is temporarily released to introduce external air, and the pressure inside the body is lowered to atmospheric pressure or close thereto. However, hitting the flow valve 8 may damage the flow valve 8, and there is a problem that a risk may follow each time because it involves excessive labor.

The present invention is to solve the above problems, an object of the present invention is to provide a rapid air valve that can be safely and easily separated from the water pipe.

In addition, another object of the present invention is to provide a rapid air valve that does not rust or rust even in frequent contact with water and air.
