Abstract
A kind of Novel rotary valve core, it comprises valve plate (1), eccentric shaft (2), axle (3), eccentric shaft mount pad (4) and axle mount pad (5), the lower surface of valve plate (1) is provided with one group of reinforced rib (1-1), valve plate (1) forms angle α between top and horizontal surface, α is 15 °, eccentric shaft mount pad (4) and axle mount pad (5) are arranged on the two ends of valve plate (1) respectively, one end of eccentric shaft (2) is arranged on eccentric shaft mount pad (4), and axle (3) is arranged on axle mount pad (5).The utility model advantage is: the leak tightness that improve knife gate valve, avoid because of accumulate particulate matter and leaking of causing.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of Novel rotary valve core.
Background technology
at present, rotovalve is applied in solid material pneumatic conveyor system to be used for the specialized equipment of the quantitative conveying such as discharging, packaging, mixing, principle of work is the transmission by motor, an impeller with repetitional structure is rotated in housing, the material in housing upper feed bin is drawn off from bottom equably.Rotovalve is widely used in plastic working, mining industry, grocery trade, manufacture and chemical industry, in use there is following shortcoming: because upper surface is plane when 1, using, easily leak.2 insufficient strength, after long-time use, easily damage.3, spool heavier mass, increases manufacturing cost.
Utility model content
The purpose of this utility model is exactly be applied in solid material pneumatic conveyor system to be used for the specialized equipment of the quantitative conveying such as discharging, packaging, mixing for current rotovalve, principle of work is the transmission by motor, an impeller with repetitional structure is rotated in housing, the material in housing upper feed bin is drawn off from bottom equably.Rotovalve is widely used in plastic working, mining industry, grocery trade, manufacture and chemical industry, in use there is following shortcoming: because upper surface is plane when 1, using, easily leak.2 insufficient strength, after long-time use, the deficiency of easily damage, and a kind of Novel rotary valve core is provided.
The utility model comprises valve plate, eccentric shaft, axle, eccentric shaft mount pad and axle mount pad, the cross-sectional plane of valve plate is fan-shaped, the angle on fan-shaped both sides is α, α is 13 °, the lower surface of valve plate is provided with one group of reinforced rib, eccentric shaft mount pad and axle mount pad are arranged on the two ends of valve plate respectively, and one end of eccentric shaft is arranged on eccentric shaft mount pad, and axle is arranged on axle mount pad.
Reinforced rib is arc.
The surface coverage of valve plate has rubber layer.
Valve plate, eccentric shaft mount pad and axle mount pad are one.
The utility model advantage is: the leak tightness that improve knife gate valve, avoids the particulate matter because accumulating and leaking of causing, and alleviates weight and also can reach production requirement.
accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cutaway view structural representation.
Detailed description of the invention
As shown in Figure 1, 2, the utility model comprises valve plate 1, eccentric shaft 2, axle 3, eccentric shaft mount pad 4 and axle mount pad 5, the cross-sectional plane of valve plate 1 is fan-shaped, the angle on fan-shaped both sides is α, α is 13 °, and the lower surface of valve plate 1 is provided with one group of reinforced rib 1-1, and eccentric shaft mount pad 4 and axle mount pad 5 are arranged on the two ends of valve plate 1 respectively, one end of eccentric shaft 2 is arranged on eccentric shaft mount pad 4, and axle 3 is arranged on axle mount pad 5.
Reinforced rib 1-1 is arc.
The surface coverage of valve plate 1 has rubber layer.
Valve plate 1, eccentric shaft mount pad 4 and axle mount pad 5 are one.
Alleviate the weight of spool, the requirement of valve closing and unlatching can be reached, also can use low-power machine, reach the requirement of energy-saving and emission-reduction.
