Embodiment Construction

[0024] specific implementation plan

[0025] As shown in Figure 1, 1 is a box-shaped shell (i.e. a water tank), and the front and rear panels of the box-shaped shell are respectively provided with a water inlet 1-1 and a water outlet 1-2, and 2 is the upstream baffle plate of the lifting frame, on which there is a round The water inlet 2-1 is opposite to the water inlet 1-1 on the box-shaped shell, when the upstream baffle 2 rises, the water inlet 1-1 on the shell and the water inlet 2-1 on the upstream baffle are staggered , the flow cross section at the inlet of the pressure regulator becomes smaller; 3 is the downstream baffle of the lifting frame, on which there is a water outlet 3-1 opposite to the water outlet 1-2 on the box-shaped shell, because the water outlet 3-1 is larger than the outlet The nozzle 1-2 is large, and when the downstream baffle 3 rises, the cross-sectional area of ​​the outlet of the pressure regulator remains unchanged; 4 is the connecting rod of the...

Abstract

The invention discloses a tank typed 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 tank typed shell, a water inlet and a water outlet respectively arranged on a front side wall and a back side wall of the shell. The invention is characterized in that the shell is provided with a lifting frame with a floating ball floating up and down, wherein, the lifting frame includes an upstream baffle and a downstream baffle respectively near the front inner wall and back inner wall of the shell, and the upstream baffle and the downstream baffle are respectively 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, equal starting regulation pressure and outlet pressure (the outlet pressure is designed by the height of a water level in a water tank), 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 irrigation. Background technique [0002] The pressure regulator (referred to as 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 head of the irrigation system is separated from the When the distances between the irrigation plots in the downstream are 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 ...
