What is a Pressure Relief Valve?

The pressure relief valve, also known as the safety valve, can be automatically opened and closed according to the working pressure of the system, and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the pressure relief valve, it will automatically open the pressure relief to ensure that the medium pressure in the equipment and pipeline is below the set pressure, protect the equipment and pipeline, and prevent accidents.


Pressure Relief Valve Application

Pressure relief valve can be used in a variety of environments and equipment. A pressure relief valve is a safety valve used to ensure the safety of equipment and operators. They are useful in applications where proper pressure levels are critical to proper and safe operation. Examples include power generation in oil and gas, central heating systems, and multiphase applications in oil refining and chemical processing.

Types of Pressure Relief Valves:

There are two main types of relief valve structures: 

1.spring type: The spring pressure relief valve relies on the force of the spring to seal the valve disc and the valve seat.

2.lever type: The lever pressure relief valve relies on the force of the lever and the heavy hammer

With the need of large capacity, there is a pulse pressure relief valve, also known as a pilot pressure relief valve, which consists of a main relief valve and an auxiliary valve. When the medium pressure in the pipeline exceeds the specified pressure value, the auxiliary valve is opened first, the medium enters the main pressure relief valve along the conduit, and the main pressure relief valve is opened to reduce the increased medium pressure.

How does Pressure Relief Valves Work？

The pressure relief valve is designed to withstand the maximum allowable working pressure (MAWP). In the event of an overpressure event in the system, the pressure relief valve detects pressure beyond its designed capability. The pressure relief valve will then exhaust the pressurized fluid or gas to flow out of the system from the auxiliary passage.


How to Calibrate a Pressure Relief Valve？

It is important to calibrate and test the safety valve to ensure that the valve is in proper working condition and will not fail when pressure relief is required. We have professional technicians who can help you solve this problem, if you need, please get in touch with our technicians.

1. What causes an overpressure event?


There are many causes of overpressure, but the most common are usually drain blockages, air leaks, and fires in the system. Even proper inspection and maintenance cannot eliminate the occurrence of leaks. Air pressure relief valves are the only way to ensure a safe environment for the equipment, its surroundings and the operator.


2. What is the difference between prv and psv?


The pressure relief valve is a type similar to the safety valve, also known as the overflow valve. It is specially used in places with high pressure, such as power stations, boilers, and containers. When the pipeline pressure reaches a certain value, the pressure relief valve will not be as The safety valve opens suddenly, and slowly opens according to the proportion of pressure. It will open according to the proportion of the pressure value we adjusted earlier. When the pressure is released to a certain value, the pressure relief valve automatically closes.

Factors to consider when choosing powder filling machine

图片
Powder filling machines  are an important part of a complete powder production line. When choosing a packaging machine for your flowing powder products, there are a variety of models and brands to choose from. You need to determine which factors are most important to your business. Some of the most important factors include product characteristics, package type, automation level, filling accuracy, production capacity, and support services. Product characteristics Powder filling machines can handle different types of powders or granules. Some are better suited for free-flowing powders, while others are best suited to handle non-free flowing products. In addition to the flow pattern of the powdered product, you should also consider its compressibility, viscosity, shape and size.   Packaging type Choose how you will package your powder products. You can use sticks,  bags , cans, bottles or any other type of container. For each type of packaging, you will need a different mac...

How does the concrete batching plant work?

图片
A  concrete plant, ​   also known as a batch plant or batching plant, is a device that combines various ingredients to form concrete. Some of these inputs include sand, water, aggregate (rocks, gravel, etc.), fly ash, potash, and cement. There are two types of concrete plants: 1. Ready mix plants (A ready mix plant combines all ingredients except for water at the concrete plant. This mixture is then discharged into a ready mix truck (also known as a concrete transport truck). Water is then added to the mix in the truck and mixed during transport to the job site) 2.  Central mix plants .(A central mix plant combines some or all of the above ingredients (including water) at a central location. The final product is then transported to the job site. Central mix plants differ from ready mix plants in that they offer the end user a much more consistent pr...

Types and Applications of Ball Valves

图片
Types of ball valves: There exist two different  types of ball valves ​. The first is the full port valve and another one is the standard port. The prime distinguishing factor between these two valve types is the size of the ball. In the full port ball valve, a bigger-sized ball is used to control the fluid flow, however, a small ball is utilized in the case of the standard port valve. The size of the ball is smaller than the pipeline with a smaller port. The pipe is just one size plus compared to the standard port through which the fluid flows. Floating and Fix Ball valve For the floating type, a compressed spring is utilized to push the body of the valve with the objective to hold the surface of the valve tightly. Thus, the consistent hold of the vale seat leads to ensuring the string is tight. On the contrary, in the fixed valve type, the valve seat can be removed while the ball remains fixed to the specific position. The attached spring is responsible for compression and adjust...
