The following is a detailed introduction to the embodiments of the present invention;

Fig. 1 is a schematic diagram of the structure of the single valve plate water impact non-return floor drain of the embodiment 1 of the water impact non-return drainage device of the present invention. The floor drain is composed of a fixed shell 1 fixed on the ground surface, a water grate 2 on the fixed shell, an oblong tubular permanent magnetic check valve that is convenient for loading and unloading on the fixed shell and is inserted upright into the drain pipe 22 installed on the floor structure layer 20 Ontology 3 consists of three parts.

The basic working principle of the floor drain is an upright long cylindrical permanent magnet non-return valve body 3 hinged with a single valve plate 8. When the water inlet 4 exceeds the set valve plate 8 to touch the water level, the water pressure exceeds The magnet in the valve body 3 and the permanent magnet attraction of the valve plate 8 immediately touch the valve plate 8, drain water quickly, generate water impact, and help to clean the drainage pipe; when the water intake is large, the resistance is small and the flow rate is large; when the water intake Small, when the water level does not reach the touch-off height, the valve plate 8 is closed to avoid the phenomenon that the silt and debris deposits caused by the small water flow block the horizontal drainage pipe.

When a negative pressure siphon suddenly occurs in the drainage pipeline, the valve plate will automatically open, and then the pipeline will be automatically replenished with air, and then the non-return seal will be restored in time to avoid the occurrence of the buckle-bowl floor drain seal being sucked dry, resulting in the failure of the anti-odor function. Even if there is no water in the device, it can still be blocked normally, and there is no need to artificially replenish water, which is worry-free.

The total height of the floor drain is more than 3 times the maximum size of the outlet 5 caliber of the oblong tubular check valve body 3, and the valve body 3 is inserted into the outlet pipe 22 upright and coaxial, which takes up little floor space. , Bring great convenience to construction and waterproofing. And there is enough water pressure to touch the valve plate again. The fixed shell 1 has an enlarged inner cavity to accommodate more water, so as to have a greater water impact. The oblong tubular check valve 3 is fixed or removed from the fixed shell 1 through a short thread or slope-shaped boss 12, which is convenient for overall cleaning and maintenance. When the valve body 3 is installed with the fixed shell 1, the sealing ring 13 is used to realize pressure sealing. In order to prevent the valve body 3 from being inserted into the drainage pipe 22 eccentrically, the outer diameter of the lower end of the fixed shell 1 inserted into the drainage pipe 22 is compatible with the standard size of the inner diameter of the drainage pipe 22, and its length should be considered to meet the convenience of adjusting its height to meet different thicknesses of floors. . During construction and installation, sealant paste 19 is coated between the drain pipe 22, and the water drain 18 is processed on the drain pipe and the ground.

The valve plate 8 with a size just covering the closed drain port 5 is freely suspended on the shaft 14 by a side hinge. The shaft 14 is fixed on the horizontal central axis of the lower end of the valve cylinder 6 of the oblong tubular valve body 3, and the valve plate can swing freely. , the axis 14 is selected on the lower end of the valve cylinder 6 and the horizontal central axis, in order to obtain a large water impact and the maximum opening of the valve plate 8, and reduce the flow resistance.

A permanent magnet block 10 is fixed at the center of the sealing port 11 of the valve plate 8, which corresponds to the position of the soft magnetic bolt 9 fixed on the pillar body 7 of the drain port 5 in the valve cylinder 6 when the valve plate 8 is closed. Mutual attraction realizes the sealing of the drain port 5 and the valve plate is fully opened instantly when the water level exceeds the set touch-off height.

The action point of the magnetic field force is selected at the central part of the valve plate 8 and the sealing port 11 in order to ensure that the pressure distribution around the contact part with the drain port 5 is as uniform as possible for better sealing and low cost, and avoids permanent magnets. Leakage due to uneven pressure distribution in other parts; the sealing port adopts elastic sealing to better adapt to the better sealing when the sewage contains inclusions.

In order to adjust the closing and attracting pressure of the valve plate 8 to the drain port, the protruding height of the bolt 9 on the pillar body 7 is adjusted, or other placement methods of magnets are adopted, but the suction force of the two still has to act on the central part of the sealing port 11 The purpose of adjustable suction force and closed suction pressure is to reduce the technical requirements on design, materials and installation, and only need to set the height of the water level through factory debugging or on-site installation adjustment.

The reset of the valve plate 8, when there is no water, the power of the valve plate 8 to the drain port 5 is the suction force of the soft magnetic bolt 9 on the pillar body 7 and the permanent magnet block 10 at the central part of the valve plate 8; After discharge, the power of the valve plate 8 in the closing movement process to the drain port 5 is the combined force of the soft magnetic bolt 9 on the pillar body 7, the suction force of the permanent magnet block 10 in the center of the valve plate 8 and the gravity of the valve plate 8.

One side of a single valve plate 8 is hingedly fixed on the shaft 14 at the lower end of a slope plate 15 inclined inward and downward on one side of the valve cylinder 6, which is close to the horizontal central axis of the valve cylinder 6. Except for the fixed shaft 14, the slope plate 15 The inclination is to reduce water resistance and guide flow. The plane of the drain outlet 5 of the upright valve cylinder 6 slopes downward from the part below the axis of the shaft 14 on the horizontal central axis at the lower end of the valve cylinder 6 to the opposite direction of the valve plate 8, and the included angle with the vertical line of the axis of the bearing 14 is less than 40 degrees , The purpose of inclination is to reduce water flow resistance and diversion.

The other side corresponding to the slope plate 15 at the lower end of the inner wall of the upright valve cylinder 6 is fixed with a streamlined deflector 16. The deflector 16 is directly above the pillar body 7, covering the pillar body 7 and its soft magnetic bolt 9, and does not affect the The closure of the valve plate 8; the deflector 16 and the pillar body 7 can be made into one body, and a gap as large as possible is left between the deflector 16 and the slope weight 15 to reduce the flow resistance.

Since there is a larger space in the oblong tubular valve cylinder 6, a barrel-shaped second-stage filter screen 17 that is easy to unload can accommodate more impurities in the sewage, making drainage more reliable.

The lower drainage washing machine pipe can be stuck on the mouth of the valve body 3 through the bayonet 23, so that there is no water leakage and no smell.
