将压井阀和阻流阀注满海水。
将压井阀和阻流阀注满海水。
主要用于一些高压差或流阻小的工况，也可作为釜底放料阀使用。
Mainly used for high pressure or flow resistance of the working conditions, but also can be used as the bottom discharge valve.
流通能力大、流阻小。这是因为开启后阀芯位于藏球室内，阀体流道呈直筒式。
Flowing capability is big and the flow resistance is little. When the valve opening, the valve core is located inside ball cavity and the flow route is straight tube.
受结构条件的限制该结构不适应做通径DN200以下阀门，原因是阀板整体结构太厚，流阻大。
Two, by the structural constraints of the structure to do the following Path DN200 valves, valve plates are the reasons for the overall structure of thick, large flow resistance.
蝶阀在开启时蝶板与流体流向平行，流阻小，流通截面大，阀芯不易被冲刷；
When opening the valve, the valve disc is parallel with the flow direction. The flow resistance is little, the flow section is large and the core will not be eroded.
本发明提供一套自力式机械装置、自动调节活动堰板、反冲阻流器、提拉阀。
This invention provides a set of self-powered mechanical device, an auto-regulating movable weir-plate, a back-flushing buffer and lift-pull valve.
