Low-pressure pipeline water-delivering irrigation water outlet

A technology for low-pressure pipes and water outlets, which is applied in watering devices, applications, and valve lifts, etc. It can solve the problems of large internal water head loss, inability to quantitatively control the water flow, and the inability to measure flow at the water outlet, so as to prevent field erosion and reduce water pollution. Internal head loss, increased outflow effect

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] The present invention includes three major parts: an upper box body 1, a lower base 2 and a water outlet stilling pool 3.

[0017] The upper box body 1 is prefabricated with cement concrete. Its width and length are suitable for installing various opening and closing devices in the box body. The net height of the box body is suitable for turning the flip cover plate 11 upward by 70°; it should be divided into three parts during prefabrication Prefabrication: the bottom surface, top surface and two sides are the first part, the front (with water outlet) and the back are the second and third parts respectively. The first part of the prefabricated components should be appropriately arranged with steel bars or steel wires to prevent the top panel from being lifted up due to excessive force when closing the flip cover 11; the height and width of the second and third part ...

Abstract

The invention provides a Low-pressure pipeline water-delivering irrigation water outlet. The Low-pressure pipeline water-delivering irrigation water outlet comprises a lower-part base, an upper-part tank and a draining water stilling pool, wherein a vertical pipe is contained in the center of the lower base and is provided with the upper-part tank; a base-plate water inlet communicated with the vertical pipe is arranged at the bottom of the upper-part tank; two hinged supporting bases which are fixed by a fastening bolt are arranged on a bottom wall of the upper-part tank on one side of the base-plate water inlet; a turning cover plate covering the base-plate water inlet is connected with the hinged supporting bases; a circle of water-stopping rubber sheet is stuck to an upstream side of the turning cover plate; a manual screw-rod opening-closing device is mounted on a top surface of the upper-part tank and is connected with the turning cover plate through a hinge connecting rod; a water outlet is arranged on a side wall of the upper-part tank; and the draining water stilling pool with flow-measuring scales is mounted on one side of the water outlet, adjacent to the lower-part base. The low-pressure pipeline water-delivering irrigation water outlet can meet the mass flow requirements, and is low in interior water head loss, and is capable of dissipating energy, preventing erosion, quantitatively controlling the flow of drained water and promoting the uniformity of irrigation water.

Description

technical field [0001] The invention relates to a water outlet for low-pressure pipeline water delivery irrigation, in particular to a water outlet capable of measuring flow and quantitatively controlling flow for low-pressure pipeline water delivery irrigation. Background technique [0002] Low-pressure pipeline water delivery irrigation has been popularized and applied on a large scale in well-irrigated and dry farming areas. In recent years, low-pressure pipeline water delivery irrigation has also received attention in rice-growing areas, and its promotion and application prospects are good. However, the current water outlet or water supply plug made of cast iron or plastic mainly considers the needs of dry farming irrigation in well irrigation areas, and the water flow is small, which is difficult to meet the large flow irrigation requirements of rice fields. [0003] In the well irrigation area, due to the limitation of the flow rate of the pumped well, there are usuall...
