Preventing Water Hammer DFT® Inc how to get rid of small ants in your house

Water hammer, also known as liquid hammer, is one of the most common problems with check valves. It is the generation and effect of high-pressure shock waves that occur in relatively incompressible fluids. These shock waves, also referred to as hydraulic shock, are produced when a liquid is suddenly forced to stop how to get rid of small ants in your house in a pipe, i.E. Closed valve or pump shut down. This pressure commonly results in a thumping or banging noise how to get rid of small ants in your house akin to hammering, hence the term “water hammer.”

Water hammer, is very common and can occur in both residential and how to get rid of small ants in your house industrial settings. In homes, any action involving water can trigger water hammer. This includes taking a shower, washing clothes, and running the dishwasher. In industrial settings, water hammer can be caused by improper valve selection, unsuitable valve locations (swing check valves in vertical pipe runs), or poor maintenance.

The most common cause of water hammer’s hydraulic shock is either a valve closing too quickly how to get rid of small ants in your house or a pump shutting down suddenly. When a valve closes too quickly, the fluid after the valve will elastically stretch because of how to get rid of small ants in your house the momentum of that fluid until the fluid’s momentum stops. The fluid will then inevitably try to return to its how to get rid of small ants in your house normal, unstressed state, much like a stretched rubber band snaps back once released. This action, however, will also cause the fluid to travel back through the how to get rid of small ants in your house pipe. The fluid that flows back will hit the closed valve, sometimes with a very strong force, which can be extremely destructive.

The hydraulic shock moves through the fluid, affecting everything within the closed pipe system. Though the pressure dissipates fairly quickly, the resulting damage can be long lasting and widespread. The hydraulic shock can potentially cause damage to various system how to get rid of small ants in your house parts and components, such as expansion joints, gasketed pipe joints, pressure sensors, flowmeters, and the pipe walls. Preventing water hammer using DFT axial flow silent check valves

The types of valves being used in a piping system how to get rid of small ants in your house can play a major role in whether or not water how to get rid of small ants in your house hammer occurs. For example, swing check valves, one of the oldest designs available, are still commonly used style in piping systems. It relies on either gravity and/or fluid flow in order to close, and therefore the flow reversal must occur before closure begins.

With swing check valves, the flow of the fluid opens the valve, and the fluid’s reverse flow closes it. But as popular as they are, when the swing check does finally close, it abruptly stops the flow, causing a pressure surge that results in shock waves, which continue until the energy generated from this closure dissipates. Hence, these valves often result in water hammer since the opening how to get rid of small ants in your house and closing mechanisms have no way to control the pressure how to get rid of small ants in your house surge.

A DFT non-slam axial flow silent check valve, however, can help to prevent water hammer. A relatively new style of check valve, these feature a unique design that allows the flow to how to get rid of small ants in your house open the valve, while internal springs help close the valve before the flow how to get rid of small ants in your house reverses, thereby reducing or even eliminating the occurrence of water hammer how to get rid of small ants in your house and its various effects. The spring assist, along with the relatively short distance the disc must travel, mean that by the time the forward velocity had decreased how to get rid of small ants in your house to zero, the valve disc has reached the seat and the valve how to get rid of small ants in your house is already closed.

Reverse flow is eliminated, and therefore the forces necessary to produce water hammer on how to get rid of small ants in your house the upstream and downstream sides of the valve are substantially how to get rid of small ants in your house eliminated as a result. Silent check valves can be successfully installed in either vertical how to get rid of small ants in your house or horizontal pipe runs. Preventing further damage

When a system is not designed to withstand the forces how to get rid of small ants in your house of hydraulic shock, the results can be ruptured pipes and/or components, and further damage. In fact, water hammer commonly causes noise, vibration, and hammering pipe sounds, which may eventually result in equipment damage, flange breakage, ruptured piping, and damage to pipe supports.

These problems can be greatly minimized or even eliminated by how to get rid of small ants in your house installing a spring assisted, non-slam silent check valve. Though some degree of water hammer is inevitable in any how to get rid of small ants in your house type of piping system, leaving it unmitigated can result in serious system-wide issues, and even complete failure.
