Servo Hydraulic SystemWhat are the performance requirements for the throttle valve in China?
The pressure difference across the oil chamber in and out refers to the pressure difference across the valve's oil chamber when the throttle is fully open and the nominal flow rate is achieved, which is generally around 1 MPa. A low pressure difference means the pressure-reducing valve cannot provide adequate pressure compensation to the throttle valve, thereby affecting the stability of the flow rate.
2. Flow regulation range, generally servoHydraulic SystemThe wider the flow adjustment range, the better. Moreover, the flow change should be uniform during adjustment, indicating excellent adjustment performance.
3. Stable flow refers to the flow rate at which the throttle valve can operate normally, meaning the rate of change in flow does not exceed 10% and there is no occurrence of flow interruption. The stable flow of the QF type throttle valve and the QDF type one-way throttle valve is generally about 10% of the nominal flow rate.
4. Internal leakage refers to the flow rate from the inlet cavity to the outlet cavity through the clearance between the valve core and the valve body when the throttle valve is fully closed and the pressure in the inlet cavity is adjusted to the nominal pressure. The internal leakage should be minimal. Additionally, during the operation of the servo hydraulic press, it is required that the throttle valve is not prone to clogging. The flow rate through the valve should be minimally affected by temperature.
