The utility model discloses a realize like this: a flush valve installed in drainage equipment is installed on a pipeline connected with a drainage pump in a water tank of the drainage equipment and comprises a flush pipe communicated with the pipeline and a nozzle installed at the free end of the flush pipe, wherein the pipe diameter of the flush pipe is smaller than that of the pipeline and is in threaded connection with the pipeline, a filter grid is arranged at the port of the connecting end of the flush pipe and the pipeline, the filter grid is of an open grid structure, a one-way water outlet valve plate is arranged in the flush pipe and is located at the rear end of the filter grid; the caliber size of the nozzle opening of the nozzle is smaller than the pipe diameter size of the flushing pipe and the pipe diameter size of the rest part of the nozzle, and the nozzle opening of the nozzle can freely rotate around the axis of the flushing pipe at the end part of the flushing pipe.

One side of the filter grid is hinged on the inner wall of the flushing pipe, and the inner wall of the flushing pipe opposite to the hinged position is provided with a bulge for supporting the edge of the filter grid, so that the filter grid can only be opened and closed in the direction of being connected with a pipeline.

The utility model discloses a be used for installing in drainage equipment's water tank on the pipeline that meets with the drain pump, including the flushing pipe and install the nozzle on the flushing pipe, be equipped with the filter grating on the port of the link of flushing pipe and pipeline, the inside of flushing pipe is equipped with one-way water valve plate, and the nozzle mouth of installing on the flushing pipe is just to the mouth that draws water of drain pump. The utility model discloses when using, after the sewage in the water tank reachs and sets for the height, the drain pump starts and draws water to the pipeline rather than meeting, the sewage partly of entering pipeline can get into the wash pipe that meets with the pipeline, the sewage that gets into the wash pipe flows through the nozzle again, because the nozzle mouth is just to the pump mouth of drain pump, in addition, drain pump sending sewage and the pressure of additional feedwater stream, make and have very strong impact force from nozzle spun rivers, thereby wash away precipitate and the grease of the mouth gathering of pumping of drain pump, prevent that precipitate and grease from blockking up the mouth of pumping of drain pump. And the water flow sprayed from the nozzle also has a disturbing effect on the water in the water tank, so that the water tank is prevented from gathering sediment and grease. The utility model discloses though simple structure, but can be effectual the problem of gathering deposit and grease in the water tank of solution drainage equipment, can not only guarantee drainage equipment's normal operating, the maintenance cost that can also effectual reduction equipment has very high using value widely.

In the figure: 1. an external thread; 2. a filter grid; 3. a flush pipe; 4. a one-way water outlet valve plate; 5. a nozzle; 6. a pipeline; 7. a water inlet; 8. a flush valve; 9. a liquid level sensor; 10. draining pump; 11. a water tank.

Detailed Description

As shown in fig. 1, fig. 2 and fig. 3, the utility model relates to a flush valve 8 installed in a water tank 11 of a drainage device, the flush valve 8 comprises a flushing pipe 3 and a nozzle 5, an external thread 1 is arranged on the outer wall of one end of the flushing pipe 3, the external thread 1 is connected with a pipeline 6, and the nozzle 5 is installed on the other free end of the flushing pipe 3. The diameter of the flushing pipe 3 is smaller than the diameter of the pipeline 6, so that most of the sewage pumped by the drainage pump 10 can be discharged through the pipeline 6. The port of the tank connection end of the flushing pipe 3 and the pipeline 6 is provided with a filter grid 2, and the filter grid 2 is an open grid structure, as shown in fig. 1, and is used for filtering sundries entering the flushing pipe 3 from the pipeline 6 and preventing the sundries from entering the water tank 11 through the flushing pipe 3. One side of the filter grid 2 is hinged on the inner wall of the flushing pipe 3, and the inner wall of the flushing pipe 3 opposite to the hinged position is provided with a bulge for supporting the edge of the filter grid 2, so that the filter grid 2 can only be opened and closed in the direction of being connected with the pipeline 6. The structural design that opens and shuts like this is convenient for clear up the filterable debris of filter grid 2 firstly, is convenient for clear up the sediment debris in the wash pipe 3 secondly. A one-way water outlet valve plate 4 is arranged in the flushing pipe 3, and the one-way water outlet valve plate 4 is positioned behind the filter grid 2, so that water in the flushing pipe 3 can only flow in a one-way mode, namely, water flow can only flow to one end of the nozzle 5 from one end connected with the pipeline 6, and thus sundries in the water tank 11 can be prevented from blocking the thinner flushing pipe 3.

As shown in fig. 2, the nozzle opening of the nozzle 5 is designed to be closed, that is, the caliber of the nozzle opening is smaller than the diameter of the flushing pipe 3 and smaller than the diameters of the other parts of the nozzle 5, so that the flow velocity of the water flow sprayed from the nozzle 5 can be increased, and the impact force of the water flow is increased. The nozzle 5 of the utility model can freely rotate around the axis of the flushing pipe 3 at the end part of the flushing pipe 3, so that the angle of the nozzle can be adjusted. In the embodiment, the nozzle opening of the nozzle 5 is adjusted to face the water pumping opening of the drain pump 10, so that the water flow sprayed from the nozzle 5 flushes the water pumping opening of the drain pump 10, and the water pumping opening of the drain pump 10 is prevented from being blocked due to the accumulation of impurities and grease.

As shown in FIG. 3, the utility model discloses when using, at first sewage can get into in the water tank 11 through the water inlet 7 of water tank 11, when the liquid level of the sewage in the water tank 11 reached the setting value of liquid level inductor 9 in the water tank 11, drain pump 10 will start, through the sewage discharge in pipeline 6 with the water tank 11. Because the flushing pipe 3 of the flushing valve 8 is connected with the pipeline 6, sewage flowing through the pipeline 6 can also enter the flushing pipe 3 and then is sprayed out from the nozzle 5, water columns sprayed out from the nozzle openings of the nozzle 5 can directly flush the water pumping openings of the drainage pump 10, the water pumping openings are prevented from being blocked by sundries in an accumulated mode, the water columns sprayed out from the nozzle 5 also have a disturbing effect on the sewage in the water tank 11, and the water tank is prevented from accumulating and precipitating and grease.

The utility model discloses not only be used for installing on sewage promotes drainage equipment, can also be applied to on the drainage equipment of other sewage pump stations.
