The utility model discloses a constant flow valve which is characterized by further comprising a constant flow valve element arranged in a constant flow valve body, the constant flow valve element comprises a valve body and a flow dividing framework connected with the valve body, a plurality of flow channels are formed between the flow dividing framework and the valve body, the flow channels are divided into water inlets and water outlets, and the water inlets are communicated with the water outlets. Sealing rings I which are deformed under high pressure to seal the water inlets of the plurality of flow channels are mounted on the flow channels; the through-flow area of the flow channel is automatically adjusted through deformation of the first sealing ring under high pressure, the influence of pressure fluctuation on flow is effectively compensated, it can be ensured that constant flow output is achieved under different pressure conditions without a complex mechanical structure or an electronic control device, the structure is simple, response is rapid, and cost is low. And the production cost and the maintenance difficulty are also reduced.

The utility model provides a lower electrode assembly and plasma processing equipment. The lower electrode assembly comprises a pedestal used for bearing a wafer; the focusing ring assembly is arranged in the edge area of the base, and the focusing ring assembly comprises a focusing ring and an edge electrode located below the focusing ring; the base and the edge electrode are electrically connected with a radio frequency power supply; the edge electrode is arranged close to the radial inner side of the focusing ring, and the ratio of the axial projection area of the edge electrode to the axial projection area of the focusing ring is 10%-70%. The focusing ring is used for prolonging the service life of the focusing ring.

The utility model discloses a kind of proportional multi-way valves applied to wharf gangway, hydraulic pump station motor provides power source and is equipped with proportional multi-way valve, proportional multi-way valve is as control element control the movement of swing motor, telescopic cylinder and amplitude cylinder, when boarding condition, through hydraulic pump station motor start amplitude cylinder, reversing valve three control amplitude cylinder and it is lifted to set height;Reversing valve one controls swing motor and it is rotated to the top of ship;Reversing valve two controls telescopic cylinder and it is extended to specified position;Micro-motion amplitude cylinder is carried on deck on gangway;Under compensation condition, hydraulic pump station motor stops working, telescopic cylinder and amplitude cylinder are freely floating, the utility model can ensure that gangway is stably operated under different load and dynamic change, and maintenance cost is reduced.
