Abstract
The utility model relates to a kind of built-in rubber bevel-type safety check, belongs to plumbing equipment technical field.Comprise body, described tubular body is fixed with the cone rubber film of sealing and non-return body.The utility model cone rubber mould not only effectively prevents the refluence of sewage, and the inside being built in pipeline better prevents the escape of gas with foreign flavor, and keying of the present utility model realizes primarily of cone rubber film bottom fold, and opening force is little, and sealing is reliable.
Description
Technical field
The utility model belongs to plumbing equipment technical field, is specifically related to a kind of built-in rubber bevel-type safety check.
Background technique
The non-return equipment in existing sewage conduct outlet port is owing to being arranged at pipe outlet or runner mouth place and outside exposed, the defect such as therefore ubiquity is poorly sealed to a certain extent, sewage backflow, insect or toy is caused to enter the escape of body and gas with foreign flavor, because the gas with foreign flavor of sewage backflow and discharge causes puzzlement to neighbouring resident.
Model utility content
The purpose of this utility model is exactly the defect for prior art, provides a kind of built-in rubber bevel-type safety check.
The technical solution adopted in the utility model is: comprise body, and described tubular body is fixed with the cone rubber film of sealing and non-return body.
Preferred structure further, described cone rubber mould comprises the sidewall fitted with inboard wall of tube body face, the longitudinal center cross section of described sidewall is trapezium structure short bottom the length of top, described sidewall one end is sealedly connected with the obstructing surface of inclination, the described sidewall the other end is opening end, and described obstructing surface is in face of the forward flow direction setting of current in body.
Preferred structure further, the top side wall of described cone rubber mould is fixed on inboard wall of tube body face by the fixed plate identical with body radian and screw.
Preferred structure further, described body end is provided with for the connection flange with wall or body Flange joint, and described connection flange has fixed hole.
The built-in cone rubber mould of the utility model not only effectively prevents the refluence of sewage, and the inside being built in pipeline better prevents the escape of gas with foreign flavor, keying of the present utility model realizes primarily of cone rubber film bottom fold, and opening force is little, and sealing is reliable.
Accompanying drawing explanation
Fig. 1 is the utility model plan view;
Fig. 2 is the utility model side view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As shown in Figure 1 and Figure 2, the utility model comprises body 1, and body 1 inside is fixed with the cone rubber film 2 of sealing and non-return body 1.Described cone rubber mould 2 comprises the sidewall 2.1 fitted with body 1 internal face, the longitudinal center cross section of described sidewall 2.1 is trapezium structure short bottom the length of top, described sidewall 2.1 one end is sealedly connected with the obstructing surface 2.2 of inclination, described sidewall 2.1 the other end is opening end, and described obstructing surface 2.2 is in face of the forward flow direction setting of current in body 1.Sidewall 2.1 top of described cone rubber mould 2 is fixed on body 1 internal face by the fixed plate 3 identical with body 1 radian and screw 4.Described body 1 end is provided with for the connection flange 1.1 with wall or body Flange joint, and described connection flange has fixed hole 1.2.
Working principle of the present utility model: when current (or air-flow) forward flow, namely in figure shown in a direction, water flow pressure increases and pushes cone rubber film open, and the bending of cone rubber film is opened, and water can flow straightway passing through; If during current (or air-flow) reverse back stream, namely in figure shown in b direction, cone rubber film as a plug drainage conduit body, anti-backflow.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
