There is always some amount of air concentrated in water and this air appears in the form of bubbles when there is change in temperature or pressure. Additionally, there is also ingress in the pumping because of the vortex that forms at the suction inlet and also due to the malfunctioning seals in the valve body and suction pipes.

Dissolved air is also released due to the generation of turbulence in the suction and pumps. With the use of varied air valves such as a double orifice air valve, you can solve the issue of air bubbles within the pumping systems. We at Dutco Tennant LLC are exhibiting in WETEX 2022 where the double orifice air valves will be featured.

Make sure to pay a visit as the event begins from 27th September ‘22 and ends on 29th September ‘ 22. Now before you arrive, take a look at this guide to have a better understanding of air valves. Keep reading till the end to find out.

Primary Purpose Air Valve Use

The excess presence of air in a pipe can impact the flow rate and also cause a range of issues such as turbulence, increased corrosion rate, pipe churning damage, etc. With the use of an ideal air valve, operators are able to enable air to escape from the pipeline without releasing any fluids. They also help in release of air during the filling up of pipes.

The valves are designed to serve the purpose of injecting air into the pipes when they are being vacated, therefore, preventing any formation of vacuum. The presence of vacuum in pipes causes for the pipeline to collapse.

Air Valve Helping Varied Operations

With the use of air valves, operators are able to address and maintain different pipeline operations. Some of the operations in which air valve helps are -

Pipe Filling

When there is filling of the pipe, the air present inside requires to be evacuated in a regulated way. The installation of air valves at the highest points in the system enables it to accomplish that operation. The suitable diameter depends on the rate of pipe filling.

Pipe Evacuation

When there is the operation of pipe water evacuation, there needs to be entrance of air so as to prevent the appearance of negative pressures which are damaging to the pipes. With the air valve installed at the highest points of the system, this operation is carried out successfully.

Air Bleeding

As we mentioned earlier, air remains dissolved in water at all times and as the water travels through the pipe, the pressure goes down because of the frictional effect on the walls. When this pressure drop happens, the water capacity reduces in order to contain the dissolved air and this generates the small air bubbles that are dragged by the water resulting to accumulate at the highest points of the systems. 

If the accumulated air is not eliminated, the effective water circulation area is decreased and localized pressure drops occur. In extreme cases, the pipe can be clogged entirely.

The use of air valves helps in preventing all of that and enhances the intended operations.
