There are a lot of contact interfaces in engineering structures that can only holdpressure but not tension.
工程结构中存在着大量的接触界面,接触界面只能承压不能承拉。

The evolution of blank holdpressure is determined by the effect of work hardening and softening during deep drawing process.
单位压边强度随温度的变化规律与拉深成型过程中材料的软化与硬化作用有关。

The hydraulic system of injection molding machine is the representative example, it need to control cylinder speed and holdpressure, so it indeed to use pressure and flow rate multiple valve.
