Backflow prevention device for drainage and preparation method
The invention provides an anti-backflow device for drainage. The anti-backflow device for drainage comprises a barrel-shaped connector 1 used for being connected with a drainage pipe, a barrel body 2 formed by extending the barrel-shaped connector 1 outwards and an opening and closing part 3 formed at the end of the barrel body 2 and opened and closed through the pressure of water flow in the barrel body 2. The cylinder 2 is in a shape that a trumpet-shaped cylinder is gradually transited to a plane, the two conical planes 21 are in a table shape with the radial size gradually increased, and the two conical planes 21 are respectively bent inwards to be in a cone shape intersecting with the arc surface 22 at the end when viewed from the side face. Two conical planes 21 respectively extend outwards in parallel to form binding faces 31, the side faces of the two binding faces 31 are connected, the inner faces of the two binding faces 31 are attached to each other, and an opening and closing part 3 is formed. The conical plane 21 and the binding face 31 are made of elastic materials and can elastically deform in the opening direction.
本发明提供一种排水用防倒流装置，包括用于与排水管连接的筒状接口1、由筒状接口1向外延伸形成的筒体2和形成在筒体2端部，由筒体2内水流压力进行开闭的开闭部3。筒体2呈喇叭形的筒状逐渐向平面过渡的形状，两个锥形平面21呈径向尺寸逐渐增大的台状，从侧面看时两个锥形平面21分别向内弯折，与圆弧面22在端部相交的锥形。由两个锥形平面21分别向外平行延伸形成贴合面31，两个贴合面31在侧面相连，内面互相贴合，构成开闭部3。锥形平面21和贴合面31由弹性材料构成，可向张开方向弹性变形。
