Abstract
The utility model discloses a butterfly plate of can pegging graft for butterfly valve, package rubbing board personally experiences sth. Part of the body, goes up plug -in components, lower plug -in components and two sealed inserted pieces, the plate body is regular octagon, goes up plug -in components and pegs graft in the plate body upper end, and lower plug -in components are pegged graft in the plate body lower extreme, and two sealed inserted piece symmetries are pegged graft in the left and right sides of plate body, goes up plug -in components and all includes inserted bar and first grafting portion with lower plug -in components, and through the fix with screw between first grafting portion and the plate body, the sealed inserted piece passes through the fix with screw including sealed cushion and second socket portion between second socket portion and the plate body. The utility model has the advantages of with positive effect be: the utility model discloses a cost of manufacturing cost with the maintenance change under the prerequisite that does not influence its leakproofness, has been saved again to disassembling of butterfly plate, and maneuverability is strong.
Description
Technical field
This utility model belongs to butterfly valve field, especially relates to a kind of pluggable butterfly plate for butterfly valve.
Background technology
Butterfly valve is again flap valve, it it is the adjustment valve of a kind of simple in construction, can be used for the butterfly valve of the on-off control of low pressure pipeline medium and refer to that closure member (flap or butterfly plate) is disk, rotate a kind of valve reaching to open and close around valve shaft, valve can be used for controlling the flowing of all kinds fluids such as sky gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium. Pipeline acts primarily as cut-out and throttling action. Butterfly valve opening and closing element is a discoidal butterfly plate, rotates around the axis of himself in valve body, thus reaching the purpose opening and closing or regulating. Butterfly plate generally with valve-stem integrated molding, often changing together with valve rod if changing butterfly plate, increasing cost, and the deep processing of butterfly plate endoporus, not only consumptive material, difficulty of processing greatly and machining accuracy it is difficult to ensure that, have impact on the sealing property of butterfly valve.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of pluggable butterfly plate for butterfly valve, can solve the problems referred to above.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of pluggable butterfly plate for butterfly valve, including plate body, upper plug-in unit, lower plug-in unit and two sealed inserted pieces, described plate body is octagon, upper plug-in unit is plugged in plate body upper end, lower plug-in unit is plugged in plate body lower end, two sealed inserted piece symmetries are plugged in the left and right sides of plate body, upper plug-in unit and lower plug-in unit all include inserted link and the first Plug Division, fixed by screw between first Plug Division and plate body, sealed inserted piece includes seal gasket and the second Plug Division, fixed by screw between second Plug Division and plate body.
Further, the centre of described first Plug Division is provided with the first slot, is provided with the second slot in the middle of the second Plug Division, and plate body inserts in the first slot and the second slot.
Further, the cross section of described first Plug Division is �� type, and the cross section of the second Plug Division is �� type, and seal gasket is fixed on outside the second Plug Division.
Further, the top of described first Plug Division is wedge angle.
This utility model has the advantage that and has the benefit effect that this utility model achieves the disassembled of butterfly plate, under the premise not affecting its sealing, saves again manufacturing cost and the cost of maintenance replacing, workable.
