求翻译：由于制造工艺上的限制，二通插装阀腔内多是棱角结构，不是流线型结构，这会造成液体在流经二通插装阀时，流量突然增大或减少，形成流速和压力的急剧变化，这种变化的流速和压力反过来会作用在二通插装阀上，使阀体产生相应的应力和变形。是什么意思？

As the manufacturing process constraints, the two-way cartridge valve cavity is more angular structure, not the streamlined structure, which can cause fluid flow through the two-way cartridge valve, the flow rate suddenly increase or decrease in flow rate and pressure to form a sharp changes, which
