Abstract
The invention discloses a kind of pluggable butterfly plate, comprise plate body, upper plug-in unit, lower plug-in unit and two sealed inserted pieces, 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 include inserted link and the first cutting graftage part, sealed inserted piece comprises seal rubber pad and the second cutting graftage part, the cross section of the first cutting graftage part is π type, and the cross section of the second cutting graftage part is π type, and seal rubber pad is fixed on outside the second cutting graftage part.The advantage that the present invention has and good effect are: present invention achieves the disassembled of butterfly plate, under the prerequisite not affecting its sealing, in turn save the cost of manufacture cost and maintain and replace, workable.
Description
Technical field
The invention belongs to butterfly valve field, especially relate to a kind of pluggable butterfly plate.
Background technique
Butterfly valve is Flap valve again, it is the simple modulating valve of a kind of structure, the butterfly valve that can be used for the switch control rule of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate a kind of valve reaching open and close around valve shaft, valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising is cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.Butterfly plate is usually shaping with valve-stem integrated, often will change together with valve rod, increase cost if change butterfly plate, and the deep processing of butterfly plate endoporus, not only consumptive material, difficulty of processing is large and machining accuracy is difficult to guarantee, have impact on the sealability of butterfly valve.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of pluggable butterfly plate, can solve the problem.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of pluggable butterfly plate, comprise 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 include inserted link and the first cutting graftage part, fixed by screw between first cutting graftage part and plate body, sealed inserted piece comprises seal rubber pad and the second cutting graftage part, is fixed between the second cutting graftage part and plate body by screw.
Further, the centre of described first cutting graftage part is provided with the first slot, and be provided with the second slot in the middle of the second cutting graftage part, plate body inserts in the first slot and the second slot.
Further, the cross section of described first cutting graftage part is π type, and the cross section of the second cutting graftage part is π type, and seal rubber pad is fixed on outside the second cutting graftage part.
Further, the top of described first cutting graftage part is wedge angle.
The advantage that the present invention has and good effect are: present invention achieves the disassembled of butterfly plate, under the prerequisite not affecting its sealing, in turn save the cost of manufacture cost and maintain and replace, workable.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Figures 1 to 3, a kind of pluggable butterfly plate, comprise plate body 1, upper plug-in unit, lower plug-in unit and two sealed inserted pieces, described plate body 1 is octagon, upper plug-in unit is plugged in plate body 1 upper end, lower plug-in unit is plugged in plate body 1 lower end, two sealed inserted piece symmetries are plugged in the left and right sides of plate body 1, upper plug-in unit and lower plug-in unit include inserted link 2 and the first cutting graftage part 3, fixed by screw 4 between first cutting graftage part 3 and plate body 1, sealed inserted piece is comprised seal rubber pad 5 and is fixed by screw 4 between the second cutting graftage part 6, cutting graftage part 6, second and plate body 1.
The centre of the first cutting graftage part 3 is provided with in the middle of the first slot 7, second cutting graftage part 6 and is provided with the second slot 8, and plate body 1 inserts in the first slot 7 and the second slot 8.
The cross section of the first cutting graftage part 3 is π type, and the cross section of the second cutting graftage part 6 is π type, and seal rubber pad 5 is fixed on outside the second cutting graftage part 6.The top of the first cutting graftage part 3 is wedge angle.
During use, can select the plate body 1 be suitable for, be inserted on plate body 1 by upper plug-in unit, lower plug-in unit and two sealed inserted pieces respectively by screw, be located on valve seat by this device, the seal rubber pad 5 of sealed inserted piece contacts with valve base sealing.Be fixed on valve rod by inserted link 2, means of fixation can select the mode such as grafting or threaded engagement.Rotary valve rod, can drive butterfly plate to rotate.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
