Problems solved by technology

This method is at the expense of labor intensity in exchange for irrigation uniformity, which not only increases the cost of engineering materials and construction, but also requires extremely high labor intensity for management, and does not fundamentally solve the problems of uniformity and reliability of the system

Embodiment 1

[0021] Such as Figure 1-Figure 5 As shown, the low-pressure pressure flow regulator is a "T-shaped" tee, including the main body and the bypass. The longitudinal pipe end 1 of the bypass is the water inlet end for connecting the main pipe; the two horizontal pipe ends of the main body 2 is the water outlet, and the outer side of the horizontal pipe end 2 is provided with a nut 3 for connecting the drip irrigation belt; on the wall of the horizontal pipe 2 where the longitudinal pipe 1 and the horizontal pipe 2 meet, a circular platform 6 is set, and the platform 6 A flow channel 7 is arranged in the middle; a protruding rice-shaped support frame 4 is also provided on the platform 6; the end of the support frame 4 near the pipe wall is provided with a protrusion 8 that is close to the pipe wall, and the protrusion 8 is surrounded by an elastic gasket. 5 matching grooves, the elastic gasket 5 is placed in the grooves.

[0022] The principle of action is: the longitudinal pipe ...

Abstract

The invention relates to a low-voltage pressure and flow regulator, which is a T-shaped tee, the longitudinal pipe end is the water inlet end, the two transverse pipe ends are the water outlet ends, a platform is arranged in a longitudinal pipe or on a transverse pipe in the junction of the longitudinal pipe and the transverse pipe, and a flow passage is arranged in the middle of the platform; and a raised support frame is further arranged on the platform, an elastic gasket is covered on the support frame, and a gap is retained between the elastic gasket and the pipe wall. By adopting the low-voltage pressure and flow regulator, uniformity, safety and reliability of irrigation of a drip irrigation system are greatly improved; and the using quantity of field materials of the system is greatly reduced, construction, mounting, operation and management are convenient, the auxiliary pipe rotational irrigation way which is widely used in China is abandoned, large branch rotational irrigation is realized, and a foundation is laid for high-frequency irrigation and automatic drip irrigation.

Description

technical field [0001] The invention relates to a pipe joint, in particular to a flow-adjustable three-way pipe. Background technique [0002] Drip irrigation is a type of water-saving irrigation that improves water use efficiency. However, during the operation of the drip irrigation system, affected by the power supply facilities, water pumps, and a large number of manual valve operations, the pressure in the pipeline changes frequently, and the water pressure at the entrance of the drip irrigation belt varies greatly, which seriously affects the uniformity of irrigation. . Therefore, ensuring that the inlet pressure of the drip irrigation belt is stable and consistent is the technical key to the high efficiency of the drip irrigation system. [0003] In foreign countries, in order to make the flow of the drip irrigation system uniform and the system safe and reliable, the usual method is to install a pressure regulating valve on the branch pipe, and to ensure the same wa...
