Abstract
A butterfly plate of a butterfly valve relates to the field of valve manufacture, and comprises a valve clack and a valve shaft seat used for arranging a valve shaft in a penetrating manner, wherein the valve shaft seat is fixed on one side of the valve clack. The butterfly plate of the butterfly valve is characterized in that one side where the valve shaft seat is arranged, of the valve clack is connected with a tapered round platform component, and the great circle surface of the tapered round platform component is integrally connected with the valve clack. Each section of the butterfly plate of the butterfly valve is an equal geometry, so that the butterfly plate adopts an equal-strength design, all parts bear the same force, small irregular deformation of the butterfly plate under the condition of temperature change is achieved so as to endow a valve with an excellent sealing effect at low temperature.
Description
Technical field
The utility model relates to valve and makes the field, is specially a kind of butterfly plate of butterfly valve.
Background technique
As shown in Figure 1, 2, the structure of traditional butterfly plate is generally truss type or flat, and the cross-sectional geometry of these two kinds of structures is different, and the distortion that produces when butterfly plate is stressed is large, and then has affected the sealing effect of valve.
Summary of the invention
The purpose of this utility model provides a kind of stressed even, and the resistance to deformation effect is the butterfly plate of butterfly valve preferably.
The technological scheme that realizes above-mentioned purpose is: a kind of butterfly plate of butterfly valve, comprise flap and be used for placing the valve shaft seat of valve shaft, the valve shaft seat is fixed in a side of flap, it is characterized in that: be fixed with on the flap of valve shaft seat one side and be connected with taper round platform member, the large disc of taper round platform member is connected with the flap one.
The geometrical shapies such as each cross section of the present utility model is, so butterfly plate designs for equal strength, each position is stressed identical, and butterfly plate irregular deformation under the temperature variation condition is little, and the valve that makes has good sealing effect under cryogenic conditions.
Description of drawings
Fig. 1 is the structural representation of flat valve plate;
Fig. 2 is the structural representation of truss type valve plate;
Fig. 3 is structural representation of the present utility model.
Embodiment
As shown in Figure 3, the utility model comprises flap 1 and is used for placing the valve shaft seat 2 of valve shaft, valve shaft seat 2 is fixed in a side of flap 1, is fixed with on the flap 1 of valve shaft seat 2 one sides and is connected with taper round platform member 3, and the large disc of taper round platform member 3 is connected with flap 1 one.
