Sometimes, an over pressurized pipeline, pressure vessel, or pump could be the reason for severe damage. High pressure relief valves are designed and installed to prevent such ruptures from causing damage to a system or site. Applications involving liquids or gases could benefit from the use of such valves. The valves can be adjusted to a certain pressure point. So, if the pressure breaches its set point, the valve will allow the over pressurized steam, gas, or liquid to flow through a small opening to prevent a total system failure or blast. van giảm áp
As the internal pressure in the system reduces or normalizes, operations can be resumed after resetting or replacing the pressure relief valve.
The size of such a valve could range from a few inches to several feet depending on the scale of operations. With the use of the right valve, disastrous events such as accidental explosion owing to high pressure can be prevented.
Here are some desirable attributes of high pressure relief valves:
Installation: It is very important that such valves are easy to install. Typically, you would find valves that come with a union end or threaded end to integrate them into your operations. The pressure rating of these valves is a very important factor to consider during the installation phase. Valves are usually available with pressure ratings ranging from 500PSI to 10,000PSI.
Changing pressure settings: The market offers a special variety of rupture-pin based valves that are very easy to use. If the pressure levels have been breached and there is damage to valve, a simple visual inspection will be enough to identify it. Such valves can also be fitted with optional features such as a pin protector cage, a proximity sensor, and a flush port that helps clear lost circulation material before resetting.
Maintenance and replacement: Sometimes, maintenance and replacement can not only be a prohibitively expensive process, but can also be very time consuming. It is possible to change the pressure levels of the valve by changing the size of rupture pins. Valves based on such rupture pin technology are easy to maintain as compared to a rupture disk or other types of spring valves.
Costs: Most enterprises cannot afford to ignore the cost aspect of a pressure relief valve. The high maintenance and replacement costs of rupture disks and spring valves don’t always make great business sense. On the contrary, high pressure relief valves based on the rupture pin technology are a one-time investment that doesn’t incur repeated maintenance and replacement costs.
Processes such as hydraulic fracturing, heavy-duty drilling, and mud and slurry operations make use of such valves. A valve that is used in high-pressure drilling operations is referred to as a drilling valve. Similarly, one that is used in applications involving mud and slurry is known as a mud valve.
