Description

Water Hammering relaxation of Air valve

The present invention relates to an air valve device for water shock relief, and more particularly, by pressing the float ball sliding guide downwards by the spring installed on the shaft for fixing the cover, the air in the pipe is normally smoothly discharged During abnormal high pressure in the pipe, the float ball slides upward by the pressure to seal the through hole of the cover to prevent the fluid (water) flowing in the pipe due to the high pressure to be discharged to the outside, and to prevent the shock of the fluid due to the high pressure. This absorbs and mitigates, the filter unit is installed in the impact relief foreign material removal unit to filter foreign matter mixed in the fluid in the tube to prevent the flow into the air valve, the filter unit to mitigate the impact of the fluid due to the high pressure air The shock is prevented from being transmitted to the valve, the air bleed valve on the outer peripheral surface of the body of the air valve When installed, the air can continuously discharge air, which is continuously formed when the float ball closes the opening of the cover due to pressure, to smoothly flow the fluid and prevent damage and noise in the pipe. An air valve device for shock alleviation.

In general, in the water and sewage pipes, air is introduced into the pipe due to various reasons, such as when replacing aging water and sewage pipes or supplying water and sewage, and such internal air reduces the flow of water and sewage. Therefore, the air discharge valve is installed at one side of the water and sewage pipes to discharge the internal air.

Here, the cause of air inflow into the water transport pipeline, the air that is not completely removed before the pipeline is filled, if there is no device to discharge enough air before opening the check valve, the air flowing in when the pump is started, the pump suction side There is air flowing from the suction side through the vortex action, air entering the pipeline through the coupling part that is not completely sealed at the pipeline point located above the hydraulic grade line, and air flowing through the pump gland packing part.

At this time, the air amount of 5 to 10% of the flow rate may be introduced to the pump suction side by Vortex. In addition, air has fatal effects such as vibration, corrosion and deterioration of the pump as well as pipeline problems.

In addition, the staged flow in the partially filled conduit traps large amounts of air resulting in so-called white water. Turbulent flows associated with staged flow lead to a mixture of air and water that is very difficult to remove. And, air can be captured by the hydraulic jump due to flow through the partially open valve.

Here, the air discharge valve is generally installed together with a distillation valve, rather than being installed alone, so that the air discharge valve can be easily replaced after the water and sewage are separated by the distillation valve.

The air discharge valve is installed in the body having a hollow portion, the buoy is in direct contact with the outlet formed in the upper portion of the body while the upper and lower reciprocating movement by the water level of the upper and lower, or to control the discharge of air, or a separate auxiliary member By using the accessory to pressurize the auxiliary member can be divided into a method of controlling the discharge of air by the auxiliary member to control the outlet.

That is, the above two methods are to release the air inside the outside by opening and closing the outlet opening or the auxiliary member directly connected to the air outlet.

However, in the above method, a gap is generated because the outlet and the sub-port or auxiliary member for opening and closing the opening are difficult to be completely adhered to.

Therefore, if the air discharge structure in which the gap is generated is applied to a relatively small capacity, since the hydraulic pressure acts more than the buoyancy, the internal constant rises to the upper side of the float so that it is discharged to the outside through the gap of the outlet. There is a problem that leaks occur. In addition, the shock caused by the water transporting in the pipe is transmitted to cause problems such as breakage of the valve.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems,

The discharge valve 230 is formed at the end of the discharge passage 231 to open and close the communication with the outside. In this case, when the discharge valve 230 is opened, foreign matter caught in the mesh 222 of the filter unit 220 in the fluid flowing state is discharged to the discharge valve 230 together with the fluid, which can be practiced by those skilled in the art. This is not a detailed description anymore.

1 to 3 and 6, the air valve 100 is installed in the pipe (1) for discharging a large amount of water is large in size to discharge the pressure and air inside the pipe (1) to the outside Formed, and when a large amount of water is discharged, the water is quickly transported in the tube 1, thereby increasing the pressure in the tube 1. This pressure can also be discharged through the air valve 100 and the body 10 and , Float guide stand 20, cover 30, float ball 40, guide rod 50, cover 60, float ball sliding guide stand 70, air bleed valve 80 It is composed of At this time, not only the air but also a small amount of water in the tube 1 can be discharged to the outside by the high pressure, the invention for preventing this.

This prevents the float ball 40 from sliding upward in the flow of air to be transported, and thereby the air in the pipe is smoothly discharged to the outside through the air valve 100.

However, when a pressure stronger than the elastic force of the spring 63 is generated, the float ball 40 is slid upward to block the through hole 31 of the cover 30. This prevents water from being discharged to the outside at high pressures.

In addition, as shown in Figure 4, the float ball sliding guide 70 is moved to the lower side by the elastic force of the spring 63, when the flow of the flow velocity in the pipe (1), the pressure is higher than the atmospheric pressure As it is lowered, air may be smoothly introduced from the outside through the screen net 62 of the cover 60.

That is, as the outside air flows into the air valve 100 through the screen net 62 of the cover 60, the float ball 40 is slid downward, and when the pressure in the pipe 1 is normalized, the pipe 1 The air inside the) is discharged to the outside.
