Abstract

The invention discloses a low pressure large flow pressure adjuster suitable for a low pressure drip irrigation system belonging to the technical field of agricultural water-saving irrigation. The technical proposal includes a shell, a water inlet arranged at one side of the shell and a water outlet arranged at the other side of the shell; the shell is internally provided with a pressure adjusting part that can move up and down. The pressure adjusting part divides an inner cavity of the shell into an upper cavity and a lower cavity, wherein, the lower cavity has water flow, and the upper cavity is provided with a spring feedback device and the spring feedback device acts on an inner upper wall of the shell and the upper surface of the pressing adjusting part. The lower part of the pressure adjusting part extends to the inner lower part of the shell along an inner wall of the shell. The extending part is provided with a water inlet through opening and a water outlet through opening corresponding to the water inlet and the water outlet. The invention has the advantages of good pressure adjusting performance, convenient installation and use, low starting regulation pressure and outlet pressure, simple structure, convenient manufacture, low cost, convenient maintenance, etc.

Description

technical field [0001] The invention relates to a pressure regulator, in particular to a low-pressure and large-flow pressure regulator suitable for a low-pressure drip irrigation system, and belongs to the technical field of agricultural water-saving irrigation. Background technique [0002] The pressure regulator is an important part of the drip irrigation system. Its main function is to keep the water pressure downstream of the pressure regulator constant when the water pressure upstream of the pressure regulator fluctuates or when the distance between the head of the irrigation system and the downstream irrigation areas is not equal. Ensure that the water pressure at the entrance of each plot is equal, so that the drip irrigation system can maintain the uniformity of irrigation that meets the requirements. [0003] For the traditional drip irrigation system, there are currently many types of pressure regulators that are matched with it. The main structure of the pressure...
