Direct acting relief valve is often used as the pilot valve of safety valve or other pilot relief valve. ( )
举一反三
- Sequence valve can be used as relief valve. ( )
- The commonly used pressure control valve in hydraulic transmission system is ( ) A: directional valve B: relief valve C: hydraulic control check valve
- In order to ensure that the pressure difference between the front and rear of the throttle valve remains unchanged when the load changes, the flow through the throttle valve is basically unchanged. The throttle valve is often connected with ( ) to form a speed control valve, or the throttle valve and ( ) are connected in parallel to form a bypass speed control valve. A: Pressure reducing valve B: constant pressure reducing valve C: overflow valve D: differential pressure relief valve
- Relief valve is used to increase the hydraulic pressure in the system to a desired value.
- A throttle valve is a simple flow control valve, a throttle valve is virtually equal to( ).
