Floor drain plays an important role in construction drainage as an important utensil getting rid of excess surface water.Floor drain should possess two kinds of basic functions: the one, and draining is smooth and easy, can get rid of excess surface water rapidly; The 2nd, good seal can effectively prevent in the foul smell inlet chamber in the sewer pipe.The existing ubiquitous problem of floor drain mainly shows: 1. the water seal height of floor drain is not enough, and majority has only 10-30mm, and is very easily dry, causes floor drain to lose sealing function, makes in the foul smell inlet chamber in the drainage pipe; 2. a little less than the drainability of floor drain, be prone to the phenomenon of impeded drainage; 3. the self-purification ability of floor drain is poor, tangles hair, settled sludge easily, forms to stop up; 4. drain structure is unreasonable, and the water seal hold facility is poor, and easily malleation that is formed in the sewerage system and negative pressure are destroyed.
Summary of the invention
The object of the present invention is to provide that a kind of simple in structure, current are little by resistance, good sealing effect, not susceptible to plugging mechanical seal and water seal combined floor drain.
Mechanical seal of the present invention and water seal combined floor drain mainly are made up of drain cover, floor drain body, float and hose type magnetic force seal valve.Drain cover by be threaded, buckle connects or other connected mode is fixed on the floor drain body, and the inlet opening is arranged on the drain cover, excess surface water enters in the floor drain body by the inlet opening.Float is arranged in the floor drain body, matches with the delivery port of floor drain body in the lower end of float, can utilize gravity or magnetic force to reach and make float seal the purpose of floor drain body delivery port; The required gravity of float sealing floor drain body delivery port is provided by the gravity of float self or the gravity of balance weight body generation, required magnetic force can be provided by the magnetic seal composite member that is installed in float lower end and delivery port place, and float and floor drain body also can be made by magnetic material.Magnetic force between the magnetic seal composite member can act on delivery port several points on every side, also can act on the delivery port ring on every side; The magnetic seal composite member is made by magnetic material, comprises Hard Magnetic and soft magnetism, and magnetic force can produce by the magnetic material of different shape.For increasing sealing effectiveness, the lower end of float or delivery port sealing place can be installed elastic seal ring additional.When magnetic material adopts rubber magnet, can save elastic seal ring.Buoyancy that float produces and gravity or magnetic force adapt, and take into account the drainage performance and the sealing performance of floor drain; The guiding or the positioner of float can be installed, to strengthen the sealing effectiveness of floor drain on drain cover or floor drain body; The top of float can also install deflector additional, directly impacts float with the big current that prevent dischargings such as washing machine, influences the drainage performance of floor drain.The delivery port of floor drain body is installed a hose type magnetic force seal valve, utilizes magnetic force that delivery port is sealed, and the unlatching of hose type magnetic force seal valve relies on the gravity or the impulse force of water.
The invention has the beneficial effects as follows, mechanical seal and water seal combined floor drain switch rapidly, current by the time resistance little, be difficult for obstruction, good sealing effect, strong, the convenient maintenance of self-cleaning ability.Because floor drain has twice mechanical seal up and down and water seal is respectively arranged above the mechanical seal, so the positive negative pressure in the sewer pipe can not influence the sealing performance of floor drain, and floor drain also has good overflow-proof performance.
Description of drawings
Accompanying drawing is the structural representation of mechanical seal and water seal combined floor drain.
1. drain covers among the figure, 2. floor drain body, 3. float, 4. magnetic seal composite member, 5. magnetic seal composite member, 6. hose type magnetic force seal valve.
The specific embodiment
With reference to the accompanying drawings, mechanical seal and water seal combined floor drain are made up of drain cover 1, floor drain body 2, float 3, magnetic seal composite member 4, magnetic seal composite member 5 and hose type magnetic force seal valve 6.Drain cover 1 is installed on the floor drain body 2 by screw thread, is distributed with the inlet opening on the drain cover 1.Match with delivery port on the floor drain body 2 in the lower end of float 3, float 3 can block the delivery port of floor drain body 2 when sinking.Magnetic seal composite member 4 is fixed on the lower end of float 3, magnetic seal composite member 5 be fixed on floor drain body 2 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 floor drain body 2 is sealed; Magnetic seal composite member 4 is made by rubber magnet, can the reinforced seal effect; A hose type magnetic force seal valve 6 is installed at the delivery port place of floor drain body 2.The course of work of mechanical seal and water seal combined floor drain is as follows: current enter in the floor drain body 2 by the inlet opening on the drain cover 1 and accumulate in around the float 3, buoyancy of water in accumulating in floor drain 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 floor drain body 2, water in the floor drain body 2 are entered rapidly in the hose type magnetic force seal valve 6, and wash hose type magnetic force seal valve 6 open and enter in the sewer.Because magnetic force suffered after float 3 come-ups is very little, so the delivery port of floor drain body 2 can be opened fully, current enter in the hose type magnetic force seal valve 6 swimmingly, also can smooth opening at the gravity of current and momentum effect bottom hose formula magnetic force seal valve 6, thereby the solids that is contained in the water all can enter in the sewer.When current diminished, the water surface in the floor drain 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 under the effect of magnetic force; If there are less current to enter in the floor drain body 2 always, then float 3 is in the interruption opening; If the current that enter in the floor drain body 2 stop, float 3 no longer floats so, and the delivery port of floor drain body 2 is sealed, and will have a certain amount of water in the floor drain body 2, and forms water seal.After anhydrous the entering, hose type magnetic force seal valve 6 relies on magnetic force to seal delivery port, and water is also arranged in hose type magnetic force seal valve 6 in the hose type magnetic force seal valve 6, and forms water seal.If long-time anhydrous the entering of floor drain, the water seal water meeting evaporate to dryness in the floor drain body 2, the water seal about this moment in twice mechanical seal and the magnetic force seal valve 6 still exists, and floor drain still is in sealing state completely.
