The specific embodiment

With reference to the accompanying drawings, dual-seal floor drain core is made up of main body 6 under main body 2, float 3, magnetic seal composite member 4, magnetic seal composite member 5 and the floor drain core on floor drain core cap 1, the floor drain core.Floor drain core cap 1 is installed on the floor drain core on the main body 2 by screw thread, on the floor drain core cap 1 inlet opening is arranged.Delivery port on the lower end of float 3 and the floor drain core on the main body 2 matches, and float 3 can block the delivery port of main body 2 on the floor drain core when sinking.Magnetic seal composite member 4 is fixed on the lower end of float 3, magnetic seal composite member 5 be fixed on main body 2 on the floor drain core delivery port around, and it is corresponding with magnetic seal composite member 4, rely on the magnetic force that produces between magnetic seal composite member 4 and the magnetic seal composite member 5, the delivery port of main body on the floor drain core 2 is sealed; Magnetic seal composite member 4 is made by rubber magnet, can the reinforced seal effect.Main body 6 is installed in the lower end of main body 2 on the floor drain core under the floor drain core, and the water inlet of main body 6 is exactly the delivery port of main body 2 on the floor drain core under the floor drain core; There is a trap 7 lower end of main body 6 under the floor drain core.The course of work of dual-seal floor drain core is as follows: current enter on the floor drain core in the main body 2 by the inlet opening on the floor drain core cap 1 and accumulate in around the float 3, buoyancy of water on accumulating in floor drain core in the main body 2 is during greater than magnetic force between magnetic seal composite member 4 and the magnetic seal composite member 5 and float gravity sum, float 3 moments come-up, open the delivery port of main body 2 on the floor drain core, water in the main body on the floor drain core 2 are entered rapidly under the floor drain core in the main body 6, and enter in the sewer by trap 7.Because magnetic force suffered after float 3 come-ups is very little, so the delivery port of main body 2 can be opened fully on the floor drain core, the current non-resistance, trap 7 can adopt lower water seal, thereby the solids that is contained in the water all can enter in the sewer.When current diminished, the water surface on the floor drain core in the main body 2 descended, and float 3 also descends thereupon; In the time of in float 3 drops to magneto motive scope, 3 moments of float are blocked the delivery port of floor drain core under the effect of magnetic force; If there are less current to enter on the floor drain core in the main body 2 always, then float 3 is in the interruption opening; The current in the main body 2 stop on the floor drain core if enter, and float 3 no longer floats so, and the delivery port of main body 2 is sealed on the floor drain core, will have a certain amount of water in the main body 2 on the floor drain core, and form water seal.After main body 6 interior anhydrous the entering, the water in the trap 7 no longer flow out, and form water seal under the floor drain core.If long-time anhydrous the entering of floor drain core, the water seal waters on the floor drain core in the main body 2 can evaporates to dryness, and the water in the trap 7 is because of being difficult for evaporate to dryness in sewer pipe, so double seal still exists, floor drain core still is in sealing state completely.
