Property.
Detailed description of the invention
Fig. 1 be the utility model proposes structural schematic diagram.
In figure: runner 1, pull ring 2, piston rod 3, semilune butterfly plate 4, spring 5, valve body 6, top cover 7, cross bar 8, piston 9, ring
Shape air bag 10, stabilizer sleeve 11, end cap 12, hollow valve rod 13.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, a kind of wear-resisting antiscour butterfly valve, including valve body 6, the inner wall of valve body 6 are rotatably connected to hollow valve rod 13,
The upper end of hollow valve rod 13 is through valve body 6 and is removably connected with runner 1, is equipped with piston rod 3, piston rod 3 in hollow valve rod 13
Upper end be connected with the cross bar 8 of perpendicular setting, and the upper end side wall of hollow valve rod 13 is equipped with cunning corresponding with cross bar 8
Mouthful, the lower end of piston rod 3 is connected with the side of piston 9, and the other side of piston 9 is connected by the inner wall of spring 5 and hollow valve rod 13
Connect, hollow valve rod 13 is located at one section in valve body 6 connection there are two symmetrically arranged semilune butterfly plate 4, semilune butterfly plate 4 it is outer
Circle is connected with annular air-pocket 10, and annular air-pocket 10 is connected to by conduit with the inside of hollow valve rod 13, and the inner ring of valve body 6 is equipped with
Arc groove corresponding with annular air-pocket 10, the both ends of cross bar 8 are respectively connected with pull ring 2, convenient for pull cross bar 8, arc groove it is interior
Wall is connected with elastic washer, improves leakproofness.
Hollow valve rod 13 be located at outside valve body 6 one section is respectively sleeved on stabilizer sleeve 11 and end cap 12, and end cap 12 is connected to
