Abstract
The utility model provides a horizontal butterfly plate valve used in slurry and fluid conveying industrial pipelines, which comprises a shell body, a valve plate and a rotation mechanism of a valve plate. The utility model has the improvements that a rotation shaft of the valve plate is positioned at one side of the valve plate; a center line of the rotation shaft of the valve plate is positioned above or below a center line of a valve passage; when the valve is in the state of full opening, the valve plate is positioned above the center line of the valve passage. The valve plate is an elliptical valve plate, and the rotation shaft of the valve plate is positioned at one side of a minor axis of an ellipse of the valve. The horizontal butterfly plate valve with the structure has the advantages of wear resistance and good sealing performance.
Description
The utility model relates to a kind of valve that is used for slurry body and fluid industrial pipeline, particularly Horizontal butterfly valve.
The valve plate of present known Horizontal butterfly valve is a circular valve plate, the axial line of valve plate turning cylinder is by the center of symmetry of valve plate and the axial line of passage, when valve is in the complete opening state, valve plate is positioned on the axial line of valve passage, because the large particulate matter of slurry concentrates on the passage axial line with current downflow in the pipeline, the plate surface wear that is positioned at passage axial line below valve plate is serious; The butterfly plate valve of this structure is to rely on the inwall of valve passage and the radially contact seal of valve plate, switching process sealing surface wear at valve is serious, the radial dimension of passage increases, the radial dimension of valve plate reduces, and makes valve closing not tight, the butterfly plate valve of this structure, when slurry body, the inwall of the particulate material washout valve door in the slurry makes the passage serious wear of gate, has shortened the service life of gate.
The purpose of this utility model is to provide a kind of Horizontal butterfly valve, to overcome the deficiency of above-mentioned valve.
The utility model is achieved in that a kind of Horizontal butterfly valve that is used for slurry body and fluid industrial pipeline, it comprises housing, valve plate and valve plate rotating mechanism, its improvements are sides that the valve plate turning cylinder is positioned at valve plate, the axial line of valve plate turning cylinder is positioned at the top or the below of valve passage axial line, when valve was in the complete opening state, valve plate was positioned at the top of valve passage axial line.
The utility model Horizontal butterfly valve can be that valve plate is oval valve plate, and the axial line of valve plate turning cylinder is positioned at a side of valve plate ellipse short shaft.
The utility model Horizontal butterfly valve can be a valve when being in closed condition, and valve plate is tilting in valve passage.
The utility model Horizontal butterfly valve is the interior diabase lining wearing layer of passage of valve.
The utility model Horizontal butterfly valve, the sealing surface that can be valve plate and valve passage are incomplete conicoids.
The Horizontal butterfly valve that the utility model provides has wear-resisting and advantage good seal performance.
Accompanying drawing 1: the part sectional view of a kind of version of the utility model Horizontal butterfly valve.
Accompanying drawing 2: the A-A cutaway view of accompanying drawing 1.
Accompanying drawing 3: the valve plate front view of accompanying drawing 1 constitutional formula.
Accompanying drawing 4: the valve passage of the another kind of version of the utility model Horizontal butterfly valve and valve board structure cutaway view.
The utility model Horizontal butterfly valve is described further in conjunction with implementing with reference to accompanying drawing.
Embodiment 1, Fig. 1, Fig. 2, Fig. 3 has provided embodiment of the utility model Horizontal butterfly valve, it comprises housing 1, valve plate 3 and valve plate rotating mechanism 5, valve plate turning cylinder 2 is positioned at a side of valve plate 3, valve plate turning cylinder 2 is positioned at the top of passage axial line, when valve was in the complete opening state, valve plate 3 was positioned at the top of the axial line of valve passage, and valve plate 3 is oval valve plates, valve plate turning cylinder 2 is positioned at a side of valve plate ellipse short shaft, when valve was in closed condition, valve plate was tilting in the passage of valve, diabase lining wearing layer 4 in the passage of valve.In the slurry body process, the large particulate matter in the slurry mainly concentrates on the valve passage center with current downflow, and is lighter to the wearing and tearing of valve plate, and passage inner liner abrasive resistant cast stone layer has improved the overall wear resistance of valve.In the valve switch process, though the sealing surface of valve plate and valve passage has wearing and tearing, this structure can not cause poorly sealed consequence.
Embodiment 2: what Fig. 4 provided is the valve passage and the valve board structure cutaway view of the another kind of version of the utility model Horizontal butterfly valve, valve plate turning cylinder 6 is positioned at the below of valve passage axial line, valve plate 7 is elliptoid valve plates, the position relation of valve plate turning cylinder and valve plate is identical with embodiment 1, valve plate is positioned at valve passage axial line top when valve is in the complete opening state, and the sealing surface of valve plate and valve passage is an incomplete conicoid.The passage of valve is made with wear-resistant steel.Present embodiment Horizontal butterfly valve has identical good effect with embodiment 1.
Claims (5)
1, a kind of Horizontal butterfly valve that is used for slurry body and fluid industrial pipeline, it comprises housing, valve plate and valve plate rotating mechanism, it is characterized in that the turning cylinder of valve plate is positioned at a side of valve plate, the axial line of valve plate turning cylinder is positioned at the top or the below of valve passage axial line, when valve was in the complete opening state, valve plate was positioned at the top of valve passage axial line.
