Abstract
The utility model relates to a pipeline cleaning disc valve, comprising a valve body, a left body, a valve disc, a valve stem, a driving arm, valve stem packing, a disc spring, valve disc and valve stem springs, bolts/nuts, a plug screw and a pipeline cleaning guide cylinder. After the driving arm is rotated counterclockwise, the pipeline cleaning disc valve is closed and maintains a closed state. After the driving arm is rotated clockwise, the pipeline cleaning disc valve is opened and maintains an open state, and then the pipeline cleaning guide cylinder is completely aligned with a pipeline for forming a complete full size pipeline and thus realizes pipeline cleaning. The pipeline cleaning disc valve guarantees no flow resistance for medium passing therethrough, prevents material or impurities from accumulating in a valve cavity, guarantees flexible movement, and prevents inner parts from being washed and abraded by the medium. The pipeline cleaning guide cylinder can be circular, square and rectangular in shape and can also be designed into other shapes. The pipeline cleaning disc valve is widely applied to new energy polysilicon, coal-to liquid process in coal chemical industry, pulverized coal conveying of power plants, pulp conveying in paper-making industry and slurry conveying of cement plants.
Description
Technical field
The utility model relates to a kind of plate valve with pigging and anti-plugging function.Be particluarly suitable for containing in the medium using on the pipeline that solid (powder) or solid (powder), gas, the liquid three-phase of easy alluvial mix.
Background technique
Used a large amount of plate valves on the slurry transportation pipeline in the paper pulp conveying of the coal dust conveying of the coal system of the polysilicon of new energy industry, Coal Chemical Industry oil, power plant, paper-making industry, cement plant at present.Mainly form with spring, bolt/nut, plug screw with spring, valve rod by valve body, left body, valve disc, valve rod, driving arm, stem packing, belleville spring, valve disc; Its working principle is through rotational drive arm; Make valve rod rotate an angle; Thereby valve rod drives valve disc and rotates, and realizes the switch of plate valve.Present existing plate valve does not have pigging function, easy blocking valve cavity, medium and is prone to internals to valve and produces and wash away and wear and tear.Needing pigging is under two kinds of situation: iron rust, welding slag, the silt stayed in the pipeline during 1) newly-built pipeline often requires its welding procedure are removed.Existing plate valve can not be realized the pigging function, even can these foreign material be stayed in the valve pocket, influences construction quality.2) construction project operation back find that pipeline flow reduces line clogging or carry out overhaul of the equipments after.
Summary of the invention
Can not pigging in order to overcome existing plate valve, easy blocking, flow resistance be big, internals are produced the deficiency of washing away and wearing and tearing; The utility model provides a kind of plate valve with pigging and anti-plugging function; This ability pigging road plate valve not only has the pigging function, and be difficult for to stop up valve pocket, does not have flow resistance, reduces medium washing away and wear and tear trim.
This ability pigging road plate valve; It mainly is made up of with spring, bolt/nut, plug screw, pigging guide shell with spring, valve rod valve body, left body, valve disc, valve rod, driving arm, stem packing, belleville spring, valve disc; It is characterized in that: said valve disc, valve rod, pigging guide shell are that integral structure and valve disc and pigging guide shell have an angle, and integral installation is in the valve pocket that valve body, left body form, after driving arm is rotated counterclockwise; Realize valve closing; After driving arm turns clockwise, can be in out state by pigging road plate valve, this moment, the pigging guide shell was consistent with the pipeline complete matching, formed all-pass footpath runner completely.
The utility model can pigging the beneficial effect of road plate valve be: can satisfy the pigging function, can not produce flow loss, can not cause material or impurity to be deposited in the valve pocket, prevented the obstruction of alluvial medium easily in the valve pocket, reduce medium to washing away of producing of the internals of valve with wear and tear, thereby make prolongation valve working life.
The utility model can pigging the shape of road plate valve pigging guide shell can be circular, square, rectangle or other shapes according to piping design and the actual operating mode of using.The rotation of driving arm can be manual, pneumatic.Can the clear direct contact medium of plate valve, that its material need satisfy is anti-corrosion, temperature, pressure and should meet corresponding standard with being connected of pipeline.
