(5), the specific embodiment

Be that the embodiment of the invention is introduced in detail below;

Fig. 1 is the 1-single valve plate water slug Floor drain with odour seal structural representation of the embodiment of the non-return dewatering installation of water slug of the present invention.This floor drain is by the drain cover 2 on the set casing 1 that is fixed on the ground surface layer, the set casing, conveniently assemble and disassemble and upright 3 three parts of oval tubulose permanent magnetism non retern valve body of inserting the drainage pipe 22 that is contained in floor slab structure layer 20 are formed on set casing.

This floor drain basic functional principle is the permanent magnetism check (non-return) valve body 3 of the upright oval tubular of a hinge statement of account valve plate 8, when water inlet 4 water inlets are touched the boiling water position above the valve plate of setting 8, hydraulic pressure is just above the magnet in the valve body 3 and the permanent-magnet attractive power of valve plate 8, touch out immediately valve plate 8, draining rapidly, produce water slug, help cleaning drainage pipe; Greatly then resistance is little when inflow, and flow is big; When inflow is little, water level does not reach and touches out when height, valve plate 8 closures, the phenomenon of avoiding silt that weep causes and detrital deposit to stop up the horizontal drainage pipeline.

When drainage pipe negative-pressure siphon occurred suddenly, valve plate was opened automatically, then to the automatic tonifying Qi of pipeline, in time recovered non-return blocking then, avoided taking place the water seal of inverted bowl type floor drain and was blotted, and cause the deodorant function failure phenomenon.Both made in this device anhydrous fully, still normally shutoff, not needing the people is moisturizing, saves worry.

Its overall height of this floor drain is greater than the maximum size of outfall 5 bores of the non retern valve body 3 of its oval tubulose more than 3 times, valve body 3 upright insertions in the outfall pipeline 22, and coaxial line, it is little that this mode takies ground space, to constructing and doing waterproof and bring great convenience.And there has been enough hydraulic pressure to touch out valve plate again.Set casing 1 is by the inner chamber that expands, to hold the more water yield, so that bigger water slug amount is arranged.The non retern valve 3 of oval tubulose is fixed or is unloaded with set casing 1 by short thread or domatic boss 12, is convenient to whole cleaning and maintenance.When valve body 3 is installed with set casing 1, be to realize wiper seal by sealing ring 13.For preventing that valve body 3 from inserting drainage pipe 22 off-centre, the external diameter of drainage pipe 22 parts is inserted in set casing 1 lower end and drainage pipe 22 internal diameter sizes of standard specification adapt, and its length should consider to satisfy the convenience that the different-thickness that adapts to floor is adjusted its height.Be coated with sealing compound 19 when construction and installation and between the drainage pipe 22, drainage pipe and ground are done waterproofing course 18 and are handled.

The valve plate 8 that size covers the closed row mouth of a river 5 just freely is suspended on the axle 14 with a limit hinge knot, axle 14 is to be fixed on the valve cylinder 6 lower end horizontal median axis of oval tubular valve body 3, valve plate can freely swing, axle 14 is chosen on valve cylinder 6 lower ends and the horizontal median axis, be for obtaining the aperture of big water slug amount and valve plate 8 maximums, reducing flow resistance.

Seal 11 central parts of valve plate 8 are fixed a permanent magnets 10, its be fixed on soft magnetism bolt 9 on valve cylinder 6 internal drainage mouths 5 Body of pillar 7 when valve plate 8 closure states, both position correspondences, and attract each other and realize the sealing of outfall 5 and water level are set when touching out height valve plate moment and all opened surpassing.

The application point of magnetic field force is chosen in the central part of valve plate 8 and seal 11, be to try one's best evenly for pressure distribution around guaranteeing its position that contacts with outfall 5, so that better sealing, and cost is low, and has avoided permanent magnet uneven and sew phenomenon in the pressure distribution at other positions; Seal adopts elastic packing, is still can better seal when containing field trash in sewage in order better to adapt to.

For adjusting the closed suction pressure of 8 pairs of outfall of valve plate, by being adjusted at the height that stretches out of bolt 9 on the Body of pillar 7, or take other setting of magnet, but both suction still will act on the central part and the suction adjustable size of seal 11, the adjustable purpose of closed suction pressure is for reducing the technical requirements to design, material, installation aspect, getting final product and only need to set the height and position that touches the boiling water position by product export debugging or on-the-spot installation adjustment.

Resetting of valve plate 8, when anhydrous, the power of valve plate 8 in outfall 5 closing motion processes is the suction of soft magnetism bolt 9 and valve plate 8 central part permanent magnets 10 on the Body of pillar 7; After having water to discharge, the power of valve plate 8 in the closing motion process of outfall 5 is the soft magnetism bolt 9 and the suction of valve plate 8 central part permanent magnets 10 and making a concerted effort of valve plate 8 gravity on the Body of pillar 7.

A limit of single valve plate 8 is fixed in the mode of hinge knot on the axle 14 of ramp 15 lower ends near valve cylinder 6 horizontal median axis that the below tilts in the side direction of valve cylinder 6, and ramp 15 is except that fixed axis 14, and inclination is for reducing water resistance, water conservancy diversion.Outfall 5 planes of upright valve cylinder 6, the axis that is positioned at axle 14 on the valve cylinder 6 lower end horizontal median axis certainly is with the lower part, and is downward-sloping to the opposite direction of valve plate 8, spends less than 40 with the drop wire angle of bearing 14 axis, and the purpose of inclination is for reducing current resistance, water conservancy diversion.

The fixing first-class wire deflector 16 of the opposite side of upright valve cylinder 6 inwall lower end ramp 15 correspondences, deflector 16 is covered with Body of pillar 7 and its soft magnetism bolt 9 directly over Body of pillar 7, do not influence the closure of valve plate 8; Deflector 16 can be made of one with Body of pillar 7, leaves big as far as possible gap between deflector 16 and the slope power 15, to reduce flow resistance.

Owing to have than large space in the oval tubular valve cylinder 6, the second level screen pack 17 that is provided with the tubbiness of being convenient to unload can hold more impurity in the sewage, makes draining more reliable.

Following draining washtub can be stuck on the mouth of valve body 3 by bayonet socket 23, and is water-tight, not deaden.
