Liquid supply device with layered sealing strip and connecting part with radial long and narrow slot

Abstract

The invention discloses a liquid supply device which comprises a layered sealing strip and a radial extension connecting part with a radial long and narrow slot and supplies liquid by utilizing air pressure. The liquid supply device comprises a pressure air supply device (7), a pressure chamber (8), a pressure supply pipe (9), a liquid supply pipeline (10) and a suction filtering device (20), wherein the pressure air supply device (7) is used for providing pressure for the pressure chamber (8) through the pressure supply pipe (9); the pressure chamber (8) can pressurize liquid in the pressure chamber (8) and discharge the liquid through the liquid supply pipeline (10); the suction filtering device (20) is arranged at the inside end of the liquid supply pipeline (10) and is used for filtering liquid when the liquid supply pipeline (10) sucks liquid from the pressure chamber (8); the outside end of the liquid supply pipeline (10) is used for allowing the discharged liquid to flow; a liquid inlet (81) is formed in the top of the pressure chamber (8).

Description

technical field [0001] The invention relates to a device for supplying liquid by air pressure, and more particularly relates to a device for supplying liquid by air pressure which can automatically remove flocs. Background technique [0002] The device that uses air pressure to give liquid is a kind of equipment that sprays liquid widely used in agriculture, green land maintenance and industry. The water quality used by the device that uses air pressure to give liquid varies according to the water source. Therefore, in order to prevent the device that uses air pressure to give liquid from being affected by impurities in the liquid, the device that uses air pressure to give liquid The end of the draw line often has a filter structure. [0003] However, due to the suction formed by the device that uses the air pressure to give the liquid during operation, it is easy to absorb a large amount of impurities near the end of the liquid delivery pipeline; Over time, these floccule...

AI Technical Summary

Problems solved by technology

However, in some cases, such as the maintenance of urban lawns, devices that use air pressure to deliver liquid need to draw liquid streams from some alternate liquid source, such as recycled rainwater, greywater, or even untreated ground surface Runoff water, and these devices that use air pressure to give liquid do not have the conditions for regular manual maintenance. Therefore, in this case, it is urgent to remove impurities to ensure the normal operation of the device that uses air pressure to give liquid. need
