Title:
VALVE STRUCTURE AND PRESSURE SPRAY NOZZLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/061829
Kind Code:
A1
Abstract:
Provided are a valve structure (10) and a pressure spray nozzle device (100), the valve structure (10) being used for the pressure spray nozzle device (100), and the valve structure (10) comprising a valve (12) and a valve core (14), wherein the valve (12) is provided with a liquid inlet pipeline (121), a liquid outlet pipeline (122), and a valve opening (123) located between the liquid inlet pipeline (121) and the liquid outlet pipeline (122), where the valve opening (123) is in communication with the liquid inlet pipeline (121) and the liquid outlet pipeline (122), and is used for being fitted with the valve core (14) to control the connection and disconnection of the liquid inlet pipeline (121) and the liquid outlet pipeline (122), and the centre line of the liquid inlet pipeline (121) and the centre line of the liquid outlet pipeline (122) are substantially co-planar. The centre line of the liquid inlet pipeline (121) and the centre line of the liquid outlet pipeline (122) are substantially co-planar, and there is no need to arrange a pipeline perpendicular to the centre line of the liquid inlet pipeline (121) and the centre line of the liquid outlet pipeline (122); and therefore, the invention is simple in structure and is easily formed, and can additionally reduce the number of right-angle bend pipelines in the valve structure (10) and reduce the pressure drop loss of liquid flowing in the pipelines.
