An energy-saving rain sprinkler with adjustable flow

Abstract

The invention discloses an energy-saving rain sprayer with regulated flow. A water spray valve element is arranged on the left end of an inlet water connecting pipe; internal threads are arranged on the right inner side of the water spray valve element; the water spray valve element is mounted on the inlet water connecting pipe by threads in a connecting way; external threads are arranged on the external edge face of the water spray valve element; a valve element casing pipe is arranged on the outer side of the water spray valve element; the valve element casing pipe is mounted on the water spray valve element by threads in a connecting way; a fixed bolt is arranged in the middle of the left end of the water spray valve element; a leakage flow regulating valve is arranged on the fixed bolt; a water spray hole is formed in the middle of the left end of the valve element casing pipe; a flow regulating valve is arranged on the left side of the valve element casing pipe; an oblique umbrella-shaped oblique surface is arranged on the left end face of the water spray hole; and the flow regulating valve is rotated to regulate the gap between the flow regulating valve and the umbrella-shaped oblique surface, so that mist, light rain, moderate rain and heavy rain, namely rain spray from small to large can be obtained.

Description

technical field [0001] The invention relates to a water spraying device, in particular to a water spraying head capable of adjusting the water spraying flow rate. Background technique [0002] At present, most of the drought-resistant irrigation used in farmland adopts the traditional direct irrigation method, that is, the outlet pipe is placed on the edge of the field, the drainage ditch is dug, and then it is allowed to flow along the ridge. This method not only consumes energy and wastes time, but also wastes water sources, and the irrigation speed is slow, and the water spray volume cannot be adjusted in time according to the needs of crops. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a rain sprayer with adjustable flow rate, which can adjust the amount of sprayed water according to the size of the seedlings and the drought conditions, save energy and water, and improve the irrigation sp...
