Description
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.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.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, the invention provides a kind of photovoltaic electrically-driven high-temperature resistant corrugated pipe stop valve.
Technological scheme: a kind of photovoltaic electrically-driven high-temperature resistant corrugated pipe stop valve, comprise valve body, it is characterized in that built-up welding Co base cemented carbide seal ring on the valve body, the active mechanical connection of titanizing Austenitic Stainless Steel bellows arrangement is below the valve rod and between above the flap, valve body contacts the convex-concave place and is embedded with bolt spring pad nut mechanical connection by high temperature resistant pad with valve gap, put down in the stuffing box on the valve gap Packing seat filler by Gland with the jack screw on the valve gap by very heavy nut mechanical connection, the valve rod top fits over mechanical connection in the motor driving core sleeve, the active mechanical connection of square toes and flap under the valve rod, on the top silicon solar plate is installed, silicon solar plate and upper frame and top mechanical connection, the output of silicon solar plate electric energy is electrically connected with accumulator plant the two poles of the earth, the output of storage battery electric energy is electrically connected with voltmeter, the output of storage battery electric energy is electrically connected with ammeter, storage battery is electrically connected with controller for electric consumption, and the motor driving head unit is electrically connected with controller for electric consumption.A motor driving core sleeve fits in the motor driving mandrel by motor driving head unit mechanical connection, a motor driving mandrel one changes through a motor driving core sleeve makes the valve rod lifting bar drive the lifting of titanizing Austenitic Stainless Steel bellows arrangement, valve gap top endoporus gas-distributing motor driving head core sleeve mechanical connection, interior gas-distributing motor driving head mandrel is by motor driving core sleeve's lateral pin mechanical connection in the motor driving core sleeve.
Technique effect: owing to adopt such scheme, simple in structure, easy for installation, flange connects convenient disassembly, dual robust bellows convenient disassembly, and product structure is reasonable, sealing is reliable, dual robust sylphon seal design guarantees the zero leakage of valve rod.Do not have fluid loss, reduce energy loss.Sealing surface weld deposit Co base cemented carbide, wear-resisting, corrosion resistant, good, the long service life of friction resistant performance, bellows titanizing Austenitic Stainless Steel is wear-resisting, corrosion resistant, good, the long service life of friction resistant performance, modified and the surfaces nitrided processing of valve rod has good anti-corruption and friction resistant performance; The indication of valve rod lifting position, more directly perceived, be applicable on the pipeline of various operating modes such as petroleum industry, cut off or connect the pipeline medium.
