Problems solved by technology

[0002] Fertilization equipment, pressure regulation equipment and filtration equipment currently used in the field of agricultural micro-irrigation technology are mostly set independently. Fertilization, pressure regulation and filtration are realized through separate installation of fertilization tanks, mesh filters and flow regulating valves, and combined use; Fertilization , Filtration and pressure regulation series equipment have high production costs and complex operations during installation and use, which largely limits the popularization and application of micro-irrigation technology

Embodiment Construction

[0020] figure 1 and figure 2 It is an embodiment of the present invention. The main inventive idea in the figure is to design the fertilization tank 4 , the filter screen 3 and the pressure regulating device 1 as a whole, wherein the pressure regulating device 1 is arranged at the end of the water inlet pipe 6 .

[0021] figure 1 and figure 2 The given embodiment is a float type pressure regulating device, which is composed of a pressure regulating elastic pad 1-1, a float 1-3 and a water inlet pipe joint arranged in the water inlet pipe; the pressure regulating elastic pad is a ring with internal teeth 1-2. The floats 1-3 are placed on the inner teeth of the pressure regulating elastic pad; a pressure regulating channel is formed between the float and the pressure regulating elastic pad; the area of ​​the pressure regulating channel is theoretically smaller than the water inlet area of ​​the water inlet pipe. Therefore, the water velocity in the pressure regulating chann...

Abstract

The invention provides a filtering fertilization tank with automatic pressure regulation. The pressure regulating device is arranged on the water inlet pipe of the fertilization tank, the filter screen is arranged in the fertilization tank and connected with the water outlet pipe, and the inlet and outlet pipes are fixed on the end cover of the fertilization tank. The pressure regulating device is a float arranged in the water inlet pipe and a pressure regulating elastic pad stuck on the pipe wall. The technical progress effect of the present invention is manifested in the combination of fertilization, filtration and water pressure adjustment equipment used in drip irrigation or micro-spray irrigation into a whole, which greatly reduces the cost of irrigation supporting equipment, and automatically controls the water pressure entering the fertilization tank Keep constant, improve the use function of the equipment.

Description

Technical field [0001] The invention relates to an automatic pressure-regulating filter and fertilization tank, which is used for irrigation and fertilization of farmland water-saving irrigation systems, and is especially suitable for pre-pressure regulation and filter fertilization of drip irrigation or micro-spray, and belongs to the technical field of agricultural water-saving irrigation equipment. Background technique [0002] At present, most of the fertilization equipment, pressure regulating equipment and filtration equipment used in the field of agricultural micro-irrigation technology are set up independently. Fertilization, pressure regulation and filtration are realized through the separate installation of fertilization tank, mesh filter and flow control valve, which can be used in combination; , filtration and pressure regulation series equipment has high production cost and complicated operation in installation and use, which greatly limits the popularization and...
