Technical field:
The present invention relates to the moving stop valve of a kind of photovoltaic electric drive.
Background technique:
At present, known stop valve, the open-shut device with stop valve are the flaps of plug type, and sealing surface is the plane or the conical surface, the center line moving linearly of flap longshore current body.The movement pattern of valve rod has elevating lever-type.Stop valve only is applicable to standard-sized sheet and complete shut-down, does not allow to do to regulate and throttling.Belong to forced seal formula valve,, do not leak with forced seal face so when valve closing, must exert pressure to flap.When medium enters valve by the flap below, the required resistance that overcomes of steering force is the frictional force of valve rod and filler with by the thrust that pressure produced of medium, the power that the force rate of closing valve is opened valve is big, so it is big that the diameter of valve rod is wanted, otherwise the fault of valve rod bending can take place.In recent years, after occurring from self-packing valve, the MEDIA FLOW of stop valve enters valve pocket to just changing by the flap top, and at this moment, under the pressure medium effect, the power of closing valve is little, and it is big to open the power of valve, and the diameter of valve rod can correspondingly reduce.Simultaneously, under the medium effect, the valve of this pattern is also tighter.When stop valve was opened, the Lift of flap was 25% of nominal diameter～30% o'clock, and it is maximum that flow has reached, and the expression valve has reached fully open position.So the fully open position of stop valve should be decided by the stroke of flap.Common material can not high-corrosion resistant, has influenced working life.Again away from power supply line, the workman controls very heavy as large bore valves.
Summary of the invention:
In order to solve large bore valves again away from power supply line, the workman controls very heavy problem, in order to solve stop valve forced seal formula valve, when valve closing, must exert pressure to flap, with the technical problem that forced seal face does not leak, common material can not high-corrosion resistant, has influenced the technical problem in working life.The invention provides a kind of photovoltaic electrically-driven quickly and movably connected high-corrosion resistant bellows stop valve.
