Embodiment Construction

[0029] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementations.

[0030] like figure 1 Shown is a spherical button-type pressure compensation dripper with anti-suckback function, including a shell 1, a patch 13 and a spherical compensation part 4, and the shell is sequentially provided with connected pipes from top to bottom along the direction of water flow. The water inlet 3, the wide-diameter main channel 5, the variable-diameter channel 6 and the narrow-diameter main channel 9. The end of the narrow-diameter main channel away from the variable-diameter channel is the water outlet 11, and the large-diameter end of the variable-diameter channel is connected to the wide-diameter main channel. Fitting, the small diameter end of the variable diameter runner is connected and matched with the narrow diameter main channel. In this embodiment, the diameter of the large diameter end of the variable ...

Abstract

The invention relates to a spherical button type pressure compensation dripper with an anti-suck-back function, which comprises a shell and a spherical compensation component, a water inlet, a wide-diameter main flow channel, a variable-diameter main flow channel and a narrow-diameter main flow channel are sequentially arranged in the shell, and the spherical compensation component is positioned in a channel formed by the wide-diameter main flow channel and the variable-diameter main flow channel; a spiral auxiliary runner extending from the large-diameter end of the variable-diameter runner to the narrow-diameter main runner is arranged on the inner side wall of the variable-diameter runner, and an energy dissipation boss located below the spiral auxiliary runner is fixedly arranged in the narrow-diameter main runner; the water outlet end of the narrow-diameter main flow channel is covered with a patch connected with the shell, and water permeable holes are formed in the patch. The structure is simple, the shell, the compensation part and the elastic patch can be directly formed through mold injection molding or general blanking treatment, and the manufacturing process is simple; the spherical elastomer is used as a compensation component, and the durability of the spherical elastomer is far better than that of a common sheet-shaped compensation structure; the elastic patch can prevent the suck-back phenomenon generated at the water outlet during shutdown, and soil and other impurities are prevented from being sucked in.

Description

technical field [0001] The invention relates to the technical field of water-saving irrigation equipment in agricultural production, in particular to a button-type dripper with an anti-suckback function and a spherical elastic body as a compensation component, in particular to a ball with an anti-suckback function Type button pressure compensated dripper. Background technique [0002] In modern agricultural production, drip irrigation, as one of the irrigation methods with the highest water-saving efficiency, has been widely used in production scenarios such as fields, courtyards, and greenhouses. The button-type pressure compensation dripper is one of the common dripper forms in the field of drip irrigation, but the button-type pressure compensation dripper commonly used at present is usually composed of three parts: the shell body, the silicone compensation sheet and the shell end cover. The cover part is generally made of PE material by injection molding through differen...
