Detailed Description

The features of the present invention and other related features are described in further detail below by way of example with reference to the accompanying drawings, for the understanding of those skilled in the art:

referring to fig. 1-7, the symbols in the drawings are: the device comprises a regulator 1, an adjusting screw 2, a valve cover 3, an oil through hole 4, a valve body 5, a sealing cap 6, a sealing sleeve 7, a steering nozzle 8, a diaphragm 9, a closing ball 10, a fixing screw 11, a first throat hoop 12, a second throat hoop 13, a flange 14, an oil cavity A15, an oil cavity B16, a negative pressure chamber 17, a water outlet pipe 18, a submersible sewage pump 19, a prefabricated pump station 20 and a flushing valve 21.

Example (b): as shown in fig. 1-7, the embodiment specifically relates to an automatic opening and closing flush valve for a prefabricated pump station, the flush valve 21 includes a valve cover 3, a rotatable regulator 1 installed in the valve cover 3, a valve body 5, a sealing cap 6, a sealing sleeve 7, a steering nozzle 8, a diaphragm 9 and a closing ball 10, the sealing cap 6 is installed above the valve body 5 and is fastened and sealed by a first throat hoop 12, the diaphragm 9 is pressed between the valve cover 3 and the valve body 5 and is fastened by a fixing screw 11, an inner cavity of the valve body 5 includes a water inlet, a negative pressure chamber 17 and a water outlet which are sequentially arranged, a flange 14 arranged on the water inlet is fixedly installed on a water outlet pipe 18 interface of the prefabricated pump station 20 by bolts, sewage in the water outlet pipe 18 is pumped by a submersible sewage pump 19, the sealing sleeve 7 is arranged between the negative pressure chamber 17 and the water outlet and is in interference fit with the valve body 5, the diverting nozzle 8 is mounted on the water outlet and is tightly sealed by a second throat band 13.

As shown in fig. 4-6, the regulator 1 is monolithic and the starting material is a hexagonal profile. The regulator 1 is provided with a plurality of small holes with different apertures in the radial direction, one of the small holes is communicated with the oil through hole 4 of the valve cover 3, the upper part of the valve body 5 is provided with an oil cavity A15, an oil cavity B16 is arranged between the lower part of the diaphragm 9 and the valve cover 3, and the oil cavity A15 is communicated with the oil cavity B16 through the oil through hole 4 and the small hole. The regulator 1 is fixed on the valve cover 3 only through one adjusting screw 2, and the adjusting screw 2 is taken out to rotate the regulator 1, so that the purpose of changing the oil passing amount and regulating the time by switching small holes with different apertures can be achieved.

As shown in fig. 1 to 7, the working method of the automatic open/close flush valve for the prefabricated pump station in this embodiment is as follows:
