Back Pressure Valve
High Performance Stainless Steel Relief Pressure Safety Valve for Dosing Pump
What type valve of back pressure valve?
A back pressure valve (Back Pressure Valve) is a type of valve used to control the pressure of a fluid, which allows the fluid to maintain a certain pressure in the pipeline. Back pressure valves are usually installed at the end of a pipeline to prevent back flow or reflux of fluid in the pipeline and to control the flow rate and pressure of the fluid. The working principle of the back pressure valve is to control the fluid pressure by adjusting the opening of the valve. When the pressure in the pipeline exceeds the set value, the valve closes automatically to prevent the fluid from flowing backward or refluxing. Back pressure valves are widely used in chemical industry, petroleum, natural gas, water treatment and other fields.
How does back pressure work?
A back pressure valve is used to control the direction of fluid flow and pressure. It works by utilizing a spring or piston inside the valve so that the fluid can only flow in one direction while preventing reverse flow. When the fluid flows in the forward direction, the valve opens and the fluid can pass freely. When the fluid flows in the reverse direction, the valve closes and prevents the fluid from passing. Which achieve the purpose of controlling the direction of fluid flow and pressure. In industrial production, back pressure valve is often used to control the flow and pressure in the piping system to ensure the normal operation of the system.
What is function of back pressure?
Its function is to maintain a certain back pressure or back flow prevention in the piping system. In the process of liquid or gas flow, if the pressure in the pipeline is lower than a certain value, it will lead to the reverse flow of liquid or gas, this phenomenon is called back flow. Back pressure valve can be adjusted by adjusting the valve opening. So that the pressure in the pipeline to maintain within a certain range, thus preventing the occurrence of back flow phenomenon.
Can a throttle valve be used as a back pressure valve?
Throttle valves can be used as back pressure valves. But their performance and effectiveness may not be as good as a specially designed back pressure valve. The back pressure valve is to control the pressure in a piping system to prevent excessive pressure from damaging the system. Throttle valves, on the other hand, are mainly used to regulate flow and pressure. and their structure and working principle are different from those of back pressure valves. Therefore, if you need to strictly control the back pressure in the piping system, it is recommended to choose a specially designed back pressure valve.
