Abstract
The utility model relates to a butterfly valve, in particular to a butterfly valve plate for an ocean engineering vessel. The butterfly valve plate for the ocean engineering vessel mainly solves the technical problems that machining is carried out on a thrust face of a valve rod hole of the butterfly valve plate in the prior art, manpower and material resources are wasted, the strength at the connecting part of the valve plate and a valve body valve rod is poorer, the service life is shorter and the like. The butterfly valve plate for the ocean engineering vessel comprises a valve plate body (1) and is characterized in that the middle of the valve plate body (1) is upwards bulged, a valve rod hole (2) is formed in the valve plate body, the middle of the valve rod hole and the valve plate body are integrally cast, the width of the middle of the valve rod hole is greater than the widths of two ends of the valve rod hole, the width of the middle of the valve rod hole is 20 mm greater than the width of the assembled valve rod, a valve body sealing face (3) is arranged at the outer edge of the valve plate body, and the valve body sealing face is a conical surface.
Description
Technical field
The utility model relates to a kind of dish valve, especially relates to a kind of ocean engineering vehicle dish valve valve plate.
Background technique
Butterfly valve is again Flap valve, it is a kind of modulating valve simple in structure, the valve butterfly valve simultaneously also can be used in the mode work of switch control of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate to reach a kind of valve of open and close around valve shaft, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the object that opens and closes or regulate.Chinese patent discloses a kind of butterfly valve (notice of authorization number: CN 103498944 A), and it comprises valve body, valve block, rotating shaft, Spindle nose cover, Sealing and seal groove, and this valve body one side is structure thin on thick middle, limit, and opposite side is plane structure; Hex-shaped shaft is processed in rotating shaft spindle nose upper end, be processed into half hex-shaped shaft at this section of hexagonal configuration position by top, Spindle nose cover is provided with and two counterbores that semicircle on & off switch is not corresponding in the same way, can be enclosed within half hex-shaped shaft, Spindle nose cover is by bolton on valve body, and sealing groove is outer up and down, left and right four direction respectively extends one section of stiffening rib.But the valve rod hole of this butterfly valve plate needs stress surface to carry out machining, wasting manpower and material resources, and the joint intensity of valve plate and valve body valve rod is poor, and working life is shorter.
Model utility content
The utility model is to provide a kind of ocean engineering vehicle dish valve valve plate, it is mainly that the valve rod hole that solves the existing butterfly valve plate of prior art needs stress surface to carry out machining, wasting manpower and material resources, and the joint intensity of valve plate and valve body valve rod is poor, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Ocean engineering vehicle dish valve valve plate of the present utility model, comprise valve plate body, the middle part of described valve plate body raises up, on valve plate body, have valve rod hole, in the middle of valve rod hole, part forms with the cast inblock of valve plate body, and in the middle of valve rod hole, part width is greater than its two ends width, and the width of the middle part of valve rod hole is than the large 20mm of width of the valve rod that assembles, the outer of valve plate body is provided with valve body sealing surface, and valve body sealing surface is the conical surface.In the middle of valve rod hole place, the direct rough-cast of part out, without machining, without stress surface, can use manpower and material resources sparingly.Only process at the working surface made allowance at two ends.
As preferably, the thickness of described valve body sealing surface is 35-45mm.Valve body sealing surface does increases design, can improve intensity, increases working life.
As preferably, the upper end of described valve rod hole is provided with the valve rod junction surface being connected with valve rod, and the thickness of valve rod junction surface is 110-120mm.Valve rod and valve plate junction surface, complete in being subject to dynamic braking herein, so torsion is quite large, also does herein thickening and process, when casting, take into full account requirement of strength herein, guarantee without casting defect.
Therefore, in the middle of valve rod hole of the present utility model place, the direct rough-cast of part out, without machining, without stress surface, can use manpower and material resources sparingly, and the contacting of valve plate and valve body, valve rod, junction surface are all done and are increased design, can improve intensity, increase working life, simple and reasonable for structure, etc. feature.

Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is side structure schematic diagram of Fig. 1;
Accompanying drawing 3 is figure A-A cross-sectional view.
Component, position and numbering in figure: valve plate body 1, valve rod hole 2, valve body sealing surface 3, valve rod junction surface 4.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the ocean engineering vehicle dish valve valve plate that this is routine, Fig. 3 as shown in Figure 1, Figure 2,, comprise valve plate body 1, the middle part of valve plate body raises up, and has valve rod hole 2 on valve plate body, and in the middle of valve rod hole, part forms with the cast inblock of valve plate body, in the middle of valve rod hole, part width is greater than its two ends width, and in the middle of valve rod hole, the width of part is than the large 20mm of width of the valve rod that assembles, and the outer of valve plate body is provided with valve body sealing surface 3, and valve body sealing surface is the conical surface.The thickness of valve body sealing surface is 39.88mm.The upper end of valve rod hole is provided with the valve rod junction surface 4 being connected with valve rod, and the thickness of valve rod junction surface is 117.6mm.
When use, be encased in the valve body of butterfly valve.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
