How Does A Hydraulic Pressure Relief Valve Work?
A hydraulic pressure relief valve, or a pressure relief valve or safety valve, is a crucial component in hydraulic systems. Its primary function is to protect the system from overpressure by releasing excess fluid when the pressure exceeds a predetermined limit. Let’s explore how a hydraulic pressure relief valve works:
- Valve Operation:
- A hydraulic pressure relief valve typically consists of a valve body, a spring-loaded control element, and an adjustable spring.
- The valve body contains an inlet port, an outlet port, and a control chamber connected to the spring-loaded control element.
- Pressure Setting:
- The pressure relief valve is pre-set or adjustable to a specific pressure level.
- The pressure setting determines the threshold at which the valve opens to relieve excess pressure.
- Pressure Monitoring:
- The pressure is monitored continuously when hydraulic fluid enters the valve through the inlet port.
- If the pressure exceeds the pre-set limit, the control element is activated to relieve the excess stress.
- Control Element Activation:
- The control element, often a spring-loaded poppet or spool, responds to the excessive pressure.
- As the pressure rises beyond the set point, the force exerted on the control element exceeds the opposing party of the spring.
- Opening of the Valve:
- When the force on the control element exceeds the spring force, the valve opens, creating a path for fluid to bypass the main flow path.
- The excess fluid flows through the valve and exits via the outlet port, relieving the pressure in the system.
- Pressure Reduction:
- As the excess fluid is diverted through the relief valve, the pressure in the system decreases.
- The valve remains open until the pressure drops below the pre-set limit.
- Pressure Stabilization:
- Once the pressure decreases below the setpoint, the control element returns to its original position, closing the valve.
- The hydraulic system resumes regular operation, with the pressure controlled within the desired range.
