Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of water outlet smooth and easy, seal stable odour-proof floor drain.
Object of the present invention realizes by following technical proposal: a kind of odour-proof floor drain, the panel comprising outer cylinder body, there is the inner barrel of water inlet and delivery port and be positioned at above inner barrel, sealing plate is provided with in described inner barrel, it is characterized in that, described sealing plate is dish and is positioned at water outlet, described sealing plate edge portion is coated with seal, described seal comprises the circular body and the outward extending sealing of autonomous agent that cross section takes the shape of the letter U, and the sealing of described seal is resisted against the water outlet of inner barrel.
The odour-proof floor drain of this structure, by being coated with seal at sealing plate, utilizes the inside wall of seal and inner barrel to lean to realize sealing delivery port.And inner barrel inside wall itself is not connected with any seal, the delivery port size on this inner barrel inwall can't reduce, and the relative aperture of whole delivery port is comparatively large, and corresponding displacement is also larger, can ensure that water outlet is smooth and easy.In addition the seal is coated on outside sealing plate, and whole elastically-deformable loaded area is larger, even if sealing plate produces a little skew under the effect of hydraulic pressure, also effectively can ensure that seal effectively contacts with inner barrel inside wall, ensures sealing further.Here sealing plate plays the effect of integrated support, seal then gives certain elastic deformation space, even if sealing plate external surface has a little hollow or out-of-flatness, effectively can be offset after seal is squeezed, prevent foul smell or sewage from gap through, the sealingly secure of sealing plate can be made reliable, effectively prevent foul smell excessive.
In above-mentioned odour-proof floor drain, described sealing in the form of a ring and sealing is resisted against the lower port place of inner barrel.
The sealing of ring-type can ensure to carry out more effective cooperation with the inner barrel of annular, and in this programme, the lower port of inner barrel directly serves as delivery port, and being leant by sealing and inner barrel lower port just can directly realize sealing.The external diameter of certain sealing is now greater than inner barrel internal diameter and could realizes sealing.Time under stressed little state, sealing and inner barrel lower port fit and realize sealing, and time under stressed larger state, sealing can produce deformation under the effect of inner barrel, fits tightly after shallow decline with inner barrel.
In above-mentioned odour-proof floor drain, described sealing is made up of elastomeric material, the lower port place of described inner barrel has the arc surface that can lean with sealing, and described arc surface arranges convex surface facing inner barrel central axis direction and seamlessly transits between arc surface and inner barrel inside wall.
Common floor drain is when sealing contacts with inner barrel lower port, because sealing is made up of elastic material, there is certain deformability, therefore certain inclination and distortion can be produced after being subject to transition extruding, therefore sealing and inner barrel lower port are linear contact lay, and contact area is little, it is unreliable to seal.And this programme is provided with arc surface at the lower port place of inner barrel, led by the transition of arc surface, make sealing can produce certain inclination and produce with arc surface after being subject to External Force Acting to contact, and be more or less the same due to the angle after arc surface and sealing are tilted, shape matching is similar, therefore sealing can fit with arc surface at this moment, generating portion face contacts, and increases the area of sealing.Ensure that sealing is reliable.And common plane or inclined-plane are not all reached this effect.
