Abstract
The utility model discloses a butterfly valve dish board, its characteristics are: including the beam barrel, be provided with the shaft hole on the beam barrel, one side of beam barrel is provided with first pterygoid lamina along the axial, and the opposite side of beam barrel is provided with along the axial parallel and use the shaft hole axis as central symmetry line centrosymmetric second pterygoid lamina with first pterygoid lamina with first pterygoid lamina. The utility model has the advantages of simple structure, with the utility model discloses during supporting disk seat equipment, with the inner chamber wall direct contact of disk seat, consequently can not cause the inner chamber wall wearing and tearing of disk seat, enable the life extension of disk seat.
Description
Technical field
The utility model belongs to butterfly valve technical field, especially relates to a kind of butterfly valve dish plate.
Background technique
Cement, a kind of butterfly valve that powder material is carried often is used in the industries such as boats and ships, butterfly plate is one of significant components of butterfly valve, the main rotation by dish plate realizes the conveying in the duct of powder material or closedown, butterfly valve in off position time, dish plate and valve seat close contact, cause powder material to be stopped.Existing butterfly valve in use, owing to there is many fine solid particles in powder material, so butterfly valve is easily blocked by fine solid particles between dish plate and valve seat when cutting out, the internal chamber wall of valve seat is caused to wear and tear, of long duration also can causing leaks, so that need to change butterfly valve, bring a lot of trouble, be therefore necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of butterfly valve, and it is simple that it has structure, and the internal chamber wall of the valve seat that do not wear and tear, can make the feature that the working life of valve seat extends.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of butterfly valve dish plate, comprise beam barrel, described beam barrel is provided with axis hole, the side of described beam barrel is provided with the first wing plate vertically, the opposite side of described beam barrel be provided with vertically parallel with the first wing plate and with centrosymmetric second wing plate of the first wing plate symmetrical line centered by axis hole medial axis.
The outside of described first wing plate and the second wing plate is circular arc.
The axial length of described first wing plate and the second wing plate is greater than the axial length of beam barrel.
After adopting said structure, the utility model is compared to the prior art advantageously: structure of the present utility model is simple, when the valve seat supporting with the utility model is assembled, directly do not contact with the internal chamber wall of valve seat, therefore the internal chamber wall of valve seat can not be caused to wear and tear, can make extend the working life of valve seat.
Accompanying drawing explanation
Fig. 1 is plane structure schematic diagram of the present utility model.
Fig. 2 is the sectional view of A-A in Fig. 1.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, further illustrates below in conjunction with drawings and Examples to the utility model.
Embodiment, see shown in Fig. 1 to Fig. 2: a kind of butterfly valve dish plate, comprise beam barrel 1, described beam barrel 1 is provided with axis hole 11, the side of described beam barrel 1 is provided with first wing plate 12 of outside for circular arc vertically, the outer end lines of the first wing plate 12 are round and smooth, the opposite side of described beam barrel 1 be provided with vertically parallel with the first wing plate 12 and with the first wing plate 12 centrosymmetric outside of symmetrical line centered by axis hole medial axis second wing plate 13 that is circular arc, the axial length of described first wing plate 12 and the second wing plate 13 is greater than the axial length of beam barrel 1, the structure of the utility model uniqueness makes the utility model when assembling with valve seat supporting with it, directly do not contact with the internal chamber wall of valve seat, therefore the internal chamber wall of valve seat can not be caused to wear and tear, can make extend the working life of valve seat.
