Abstract

The invention belongs to the technology field of irrigation. The outflow constant structure comprises: an upper plane channel, wherein a plurality of primary energy dissipating units are arranged in sequence inside the upper plane channel and a water inlet is arranged at the front end of the upper planar channel; a lower plane channel, wherein a plurality of secondary energy dissipating units arearranged in sequence inside the lower plane channel, a plurality of primary energy dissipating units are respectively arranged corresponding to the plurality of the secondary energy dissipating units,and corresponding communication holes are arranged between the corresponding primary energy dissipating units and the secondary energy dissipating units; and an outlet channel, wherein each of the secondary energy dissipating units is connected to the outlet channel through an outlet and a constant flow port is arranged on the outlet channel. The invention further discloses an outflow constant method. The overall structure of the outflow constant structure has no moving parts, the energy dissipating path is automatically selected according to the water inlet pressure through the four-dimensional energy dissipation, thereby realizing constant flow and constant pressure on the outlet.

Description

technical field [0001] The invention belongs to the technical field of irrigation, and in particular relates to a method and structure for constant outflow. Background technique [0002] Outflow stability is an important method to achieve irrigation uniformity. The main function of the flow regulator is to stabilize the flow, a device that maintains a relatively stable outflow under different inlet pressures. It can automatically adjust the flow through the regulator in a relatively stable range according to the pressure inside the pipe. For example, adding a "flow regulator" (commonly referred to as "flow regulator" and "flow regulator" at the capillary inlet) can solve this problem well, so the capillary flow regulator is used more more and more popular. Strong pressure compensation, especially suitable for undulating terrain, uneven system pressure and long capillary. [0003] Combining the flow regulator with the dripper is a compensating dripper, which uses the press...
