Nowadays, companies that use pipes for the transportation of fluids rely on check valves. They are called no-return valves. This kind of valve permits liquid flow in only one direction while preventing reverse flow. Additionally, the opening and closing of these valves are dependent on the pressure of the hydraulic. In this article, we’re going to discuss the most frequent issues with these valves and some tips you can employ to avoid these issues.
Most of the time, they are utilized to feed chemical chemicals and heating and cooling systems, water lines, steam lines, and condensate lines, to name just several. In every one of these instances, this device plays an important role since it is the case that reverse flows of liquids can result in significant damage to equipment. This is why you should examine the symptoms to identify any potential issues in the device.
Common Check Valve Issues
Water hammer
A water hammer is an extremely high-pressure shock wave created because the water changes its direction abruptly. This usually occurs when the flow from downstream causes the check valve to stop in a flash. In this situation, the valve could be damaged.
Reverse flow
Usually, reverse flow occurs when the device lets water flow back in the direction upstream. This could be harmful to equipment such as discharge pumps. The reverse flow of the pump could cause it to spin the impeller in a reverse direction, which can cause significant damage to the pumps.
Improper installation
Like any other kind of mechanical equipment, faulty assembly, maintenance or even installation could result in injuries to the device. When installing the device must be in the proper direction. In addition, it is essential to be aware of the differences between the operation of various kinds of valves.
It is important to think about the capacity for flow, the place of installation for the valve, as well as how the flow is directed by the valve.
Pipeline debris
If there are a lot of detritus in the line, it may stop the check valve. This means that the valve won’t be able to close or open. In addition, the debris could also cause damage to the mechanism inside. In the end, the valve’s components could be sucked out of the valve.
Other reasons for check valve failure are worn seals on the seat and elastomers. Additionally, extreme temperatures could also trigger failure.
Preventative measures
If you are looking to avoid check valve failure and help the valves become more durable, then we recommend taking preventive steps and conducting regular maintenance.
It is essential to keep the system in good order to stop particles from building up inside the system. A simple method of doing this is to set up filters and covers made of high quality. Additionally, the system must be flushed on a frequent basis to eliminate any particles that have settled.
Another way to avoid valve failure is regular lubrication of valves. This will reduce friction between various components and increase the lifespan of the whole system. In turn, the system performs in a way that is efficient.
In the end, If you follow these guidelines to avoid any check valve malfunction and save dollars in the long run.
