Summary of the invention
The purpose of this utility model 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 core.
Mechanical seal of the present utility model and water seal combined floor drain core mainly are made up of floor drain core main body, float and hose type magnetic force seal valve.In the floor drain core main body float being arranged, matches with the delivery port of floor drain core main body in the lower end of float, can utilize gravity or magnetic force to reach and make float seal the purpose of floor drain core main body delivery port; The required gravity of float sealing floor drain core main 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 core main 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 core; The guiding or the positioner of float can be installed, to strengthen the sealing effectiveness of floor drain core on the floor drain core main 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 core.The delivery port of floor drain core main 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 beneficial effects of the utility model are, mechanical seal and water seal combined floor drain core 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 core 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 core, and floor drain core also has good overflow-proof performance.
Description of drawings
Accompanying drawing is the structural representation of mechanical seal and water seal combined floor drain core.
1. floor drain core main bodys among the figure, 2. float, 3. magnetic seal composite member, 4. magnetic seal composite member, 5. hose type magnetic force seal valve.
The specific embodiment
With reference to the accompanying drawings, mechanical seal and water seal combined floor drain core are made up of floor drain core main body 1, float 2, magnetic seal composite member 3, magnetic seal composite member 4 and hose type magnetic force seal valve 5.Float 2 is installed in the floor drain core main body 1, matches with delivery port on the floor drain core main body 1 in the lower end of float 2, and float 2 can block the delivery port of floor drain core main body 1 when sinking.Magnetic seal composite member 3 is fixed on the lower end of float 2, magnetic seal composite member 4 be fixed on floor drain core main body 1 delivery port around, and it is corresponding with magnetic seal composite member 3, rely on the magnetic force that produces between magnetic seal composite member 3 and the magnetic seal composite member 4, the delivery port of floor drain core main body 1 is sealed; Magnetic seal composite member 3 is made by rubber magnet, can the reinforced seal effect; A hose type magnetic force seal valve 5 is installed at the delivery port place of floor drain core main body 1.The course of work of mechanical seal and water seal combined floor drain core is as follows: current enter in the floor drain core main body 1 and accumulate in around the float 2, buoyancy of water in accumulating in floor drain core main body 1 is during greater than magnetic force between magnetic seal composite member 3 and the magnetic seal composite member 4 and float gravity sum, float 2 moments come-up, open the delivery port of floor drain core main body 1, water in the floor drain core main body 1 is entered rapidly in the hose type magnetic force seal valve 5, and wash hose type magnetic force seal valve 5 open and enter in the sewer.Because magnetic force suffered after float 2 come-ups is very little, so the delivery port of floor drain core main body 1 can be opened fully, current enter in the hose type magnetic force seal valve 5 swimmingly, also can smooth opening at the gravity of current and momentum effect bottom hose formula magnetic force seal valve 5, 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 core main body 1 descended, and float 2 also descends thereupon; In the time of in float 2 drops to magneto motive scope, 2 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 in the floor drain core main body 1 always, then float 2 is in the interruption opening; If the current that enter in the floor drain core main body 1 stop, float 2 no longer floats so, and the delivery port of floor drain core main body 1 is sealed, and will have a certain amount of water in the floor drain core main body 1, and forms water seal.After anhydrous the entering, hose type magnetic force seal valve 5 relies on magnetic force to seal delivery port, and water is also arranged in hose type magnetic force seal valve 5 in the hose type magnetic force seal valve 5, and forms water seal.If long-time anhydrous the entering of floor drain core, the water seal water meeting evaporate to dryness in the floor drain core main body 1, the water seal about this moment in twice mechanical seal and the hose type magnetic force seal valve 5 still exists, and floor drain core still is in sealing state completely.
