Abstract
The utility model relates to a silencer for water drainage pipelines, which is composed of a circular fixed ring which is provided with a convex table on an external side and a plurality of flow guide vanes, and one end of the flow guide vanes is fixed onto the fixed ring. The utility model has the advantages of simple structure, convenient installation, and good silencing effect. The silencer for water drainage pipelines can promote application of plastic pipes in the field of a water drainage system.
Description
The utility model relates to the pipe-line system technical field of waste water in the building, specifically relates to a kind of silencer that is installed in the sewerage system.
At present, the tubing of manufacturing with plastic materialss such as PVC, because of its light weight, inexpensive, corrosion resistant, easy advantage such as installation, be used for substituting the sewerage system of traditional material gradually by people, but it is too poor that its significant disadvantages is a soundproof effect, influence people's work and life, though people attempt by increasing wall thickness or changing the tube wall composition to reduce noise, but effect is general, and all can increase considerably cost and make the manufacturing process complexity, thereby limit the application of plastic tubes such as PVC in sewerage system.
The purpose of this utility model provides a kind of simple in structure, drainage pipe silencer that cost is low, easy for installation, to reduce drainage noise.
The technical solution of the utility model is: it is made of annular retainer ring and several guide vanes that an outside has boss, and an end of guide vane is fixed on the annular retainer ring.
The surface of guide vane of the present utility model can be rotation shape curved surface.
The utility model has the advantages that: it can single injection-molded, simple in structure, and fabricating cost is low, and is easy to install, can install many places in soil stack, when current flowed down, guide vane guiding current were the rotational flow state, move downward along tube wall, thereby greatly reduce noise.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is the utility model user mode reference drawing.
In the embodiment that accompanying drawing provides, the utility model comprises that an outside has annular retainer ring 2 and 4 guide vanes 1 of a circle boss 3, one end of 4 guide vanes 1 is uniform to be fixed on the annular retainer ring 2, and guide vane 1 and annular retainer ring 2 can be by PVC plastics single injection-moldeds.Blade height is much larger than the retainer ring height.Blade section and annular ring radially tangent line have angle, and the surface of guide vane 1 can be rotation shape curved surface, so that current rotate when flowing through better.During installation, the boss 3 in annular ring 2 outsides is inserted into pipe fitting 4 inwall bellmouth platform places, and tubing 5 is inserted by pipe fitting 4 sockets, and guide vane 1 is adjacent on tube wall, uses adhesive again.
