Description

Water Hammering Prevention of Air Valve

The present invention relates to an air valve device for preventing water shock, and more particularly, an induction pipe is installed in communication with an outer periphery of a body of an air valve, and an air vessel and an air bleeding valve are installed at an end of the induction pipe, thereby providing a float ball. When the inside of the body of the air valve is sealed by, the pressure of the fluid continuously flowing and the pressure by the air are increased so that the pressure is reduced by exhausting the air by the air bleed valve and absorbing the pressure by the air vessel. At the same time to prevent the damage and noise of the pipeline and the valve, and the filter network is installed in the foreign material removal unit to filter foreign matter mixed in the fluid in the pipe to prevent the inflow into the air valve, the filter network according to the high pressure To prevent the shock from being transmitted to the air valve by partially relieving the shock of the fluid It is.

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, air valves are 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 valve is usually installed together with a water separator valve, rather than being installed alone, so that the air valve can be easily replaced after the water and sewage are separated by the water separator valve.

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