Abstract

The utility model discloses a flow-changing nozzle of a sprayer, which can change the flow, spraying range and spray irrigation strength without replacing the nozzle. The technical scheme for achieving the purpose of the utility model is that the flow-changing nozzle of the sprayer comprises a nozzle body, wherein the nozzle body is provided with an upper shell body and a lower shell body; external thread at the upper part of the lower shell body is matched with a threaded hole at the lower part of the upper shell body; the external thread at the upper part of the upper shell body is matched with the threaded hole of the sprayer; a downward cone arranged at the center of an end plate of the upper shell body is arranged in an upper end opening of an axial water spraying hole of the lower shell body; the diameter of the cone is larger at the upper part and is smaller at the lower part; and an axial hole arranged on the end plate between the cone and the upper shell body is communicated with a drain hole in the sprayer and the water spraying hole of the lower shell body. The flow-changing nozzle of the sprayer is used for irrigation.

Description

A kind of unsteady flow amount spray nozzle
Technical field:
The utility model relates to a kind of irrigation technique, particularly a kind of unsteady flow amount spray nozzle.
Background technology:
Sprinkling irrigation is a kind of water-saving result irrigation technique preferably, and shower nozzle is the vitals in the irrigation system, and the quality of its performance has decisive role to irrigation quality, water-saving result.Existing impact driven sprinkler realizes that the change of injection flow rate generally is to change flow, range, application rate of sprinkler irrigation by changing nozzle, and this just needs to be equipped with the nozzle of plurality of specifications, but also wants the dismounting shower nozzle, the inconvenience of taking a lot of work.
Summary of the invention:
The utility model purpose provides a kind of a kind of unsteady flow amount spray nozzle that nozzle promptly can change flow, range and application rate of sprinkler irrigation of not changing.The technical scheme that realizes the utility model purpose is, a kind of changeable flow spray nozzle, comprise nozzle body, it is characterized in that: described nozzle body has upper shell and lower house, the screwed hole of the external screw thread on lower house top and upper shell bottom matches, the external screw thread on upper shell top and the screwed hole of shower nozzle match, center at the end plate of upper shell is provided with the upper port that downward cone places the axial hole for water spraying of lower house, this cone diameter is up big and down small, has the discharge orifice in axial hole and the shower nozzle and the hole for water spraying of lower house and be communicated with on the end plate between cone and the upper shell.The utility model has compared with the prior art not to be needed to change nozzle and can change flow, range and application rate of sprinkler irrigation and remarkable advantage easy to use.
Description of drawings:
Accompanying drawing is the vertical section schematic diagram of the utility model unsteady flow amount spray nozzle.
The specific embodiment:
In conjunction with following embodiment the utility model is described in detail, spray nozzle comprises upper shell 1 and lower house 5, be provided with axial hole for water spraying 4 in the lower house, the end plate that a circumferential openings is arranged on the top of upper shell, the center of this end plate is provided with the hole for water spraying upper port that downward cone 3 places lower house, and the external screw thread on upper shell top and the screwed hole of shower nozzle match.
Principle and method of operating that the utility model unsteady flow amount spray nozzle is regulated flow are, when needs increase the sprinkling irrigation flow, hand-held lower house is rotated counterclockwise, be that lower house moves down from upper shell, at this moment, the cone of upper shell moves up from the hole for water spraying of lower house, and the circulation area between cone and hole for water spraying increases, and the circumferential mouthful axial hole for water spraying ejection sprinkling irrigation water yield that through upper shell flowing water chamber 2 enter lower house of water on the end plate on upper shell top increases; If when reducing flow, the lower house that then turns clockwise gets final product.This spray nozzle only needs a spray nozzle can realize the change of flow, and it is very convenient to change flow.
