Abstract
The utility model relates to a whole opening non-return automatic shutter consisting of a valve body. The utility model is characterized in that the inside upper end of the valve body is hinged with a duck bill cover plate. The inner wall of the valve body is provided with a convex sealing ring which corresponds with the duck bill cover plate. The utility model has the advantages that the non-return automatic shutter can be wholely opened to protect pipelines from being stuffed.
Description
Technical field
The utility model relates to a kind of anti counter-flowing automatic lid actuator, and particularly a kind of standard-sized sheet leads to the anti counter-flowing automatic lid actuator.
Background technology
Backing up of sewage in the sewage conduct is very big to people's life influence in real life at present, particularly mouse, worm also can climb in the sewage conduct indoor sometimes, damage indoor article, and existing anti counter-flowing automatic lid actuator, though can prevent to pour in down a chimney, but they often can not lead to by standard-sized sheet when opening, and cause the obstruction of pipeline easily.
Summary of the invention
The purpose of this utility model is that the anti counter-flowing automatic lid actuator can not lead to by standard-sized sheet when opening in the solution prior art, causes the problem of line clogging easily.The logical anti counter-flowing automatic lid actuator of technical solutions of the utility model design standard-sized sheet comprises valve body, and it is characterized in that: going up the top in the valve body has hinge, and hinge connects the duckbill cover plate, has on the valve interior wall and the corresponding protrusion sealing ring of duckbill cover plate.The utility model has the advantages that anti counter-flowing automatic lid actuator standard-sized sheet when opening is led to, prevent line clogging.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
The specific embodiment
Comprise valve body 1 among the figure, it is characterized in that: going up the top in the valve body 1 has hinge 2, and hinge 2 connects duckbill cover plate 3, has on valve body 1 inwall and duckbill cover plate 3 corresponding protrusion sealing rings 4.During use when current forward flow through, current will be on the duckbill cover plate 3 top, valve body 1 is open-minded and since hinge 2 in valve body 1 on the top, and when turning on the duckbill cover plate 3 and valve body 1 inwall be close to, so valve body 1 does not have any obstacle when opening.When flow reversal is flow through, current are pressed in the duckbill cover plate for 3 times on the protrusion sealing ring 4 on valve body 1 inwall, and valve body 1 is closed, and block water stream passes through, when not having current at ordinary times, duckbill cover plate 3 is closed at protrusion sealing ring 4 upper valve bodies 1 that are pressed under the effect of gravity on valve body 1 inwall.
