Pressure adjusting and controlling device and sprinkler provided with same

Abstract

The invention discloses a pressure adjusting and controlling device, which relates to a water sprinkling device for irrigating green areas. The pressure adjusting and controlling device comprises a plastic guide ring, a guide rod, a telescopic slide bar, a guide sleeve and a draft line, wherein the guide rod is fixed on a rotary water pipe; the telescopic slide bar is arranged in the guide rod; one end of the telescopic slide bar is fixedly connected with the guide sleeve, and the other end of the telescopic slide bar is connected with the draft line; the guide sleeve is sleeved on the plastic guide ring; and the draft line is connected to the hydraulic valve. A sprinkler provided with the pressure adjusting and controlling device comprises a spray head, a pressure adjusting and controlling device, a rotary water pipe, a hydraulic valve, a water pipe rotation driving device and a fixed water inlet pipe, wherein one end of the rotary water pipe is connected with the spray head, and the other end of the spray water pipe is connected with the fixed water inlet pipe through the rotary joint. The magnitude of pressure is adjusted through the pressure adjusting and controlling device, so that the sprinkling distance and shape of the sprinkler can be adjusted optionally, the sprinkling shape can be matched with the practical shape of a green area, and the aims of saving water and fully irrigating are fulfilled. The sprinkler has the characteristics of simple structure, low cost and easiness for popularizing and using.

Description

technical field [0001] The invention relates to a sprinkling device for irrigating green space, in particular to a pressure regulating control device and a sprinkler with the device. Background technique [0002] At present, the sprinklers used for irrigating green spaces generally adopt the mode of rotating nozzles to sprinkle water. The sprinkler range is a circular area with the sprinkler as the center of the circle, and the distance and shape cannot be adjusted during the sprinkler process. In actual life, the shape of the green space that needs sprinkler irrigation is often irregular. For example, the long and narrow green belt in the middle of the road, the park in the middle of the street, and the green space are all non-circular irrigation areas. When ordinary sprinklers are used to sprinkle water on these non-circular green spaces, in order to ensure that all corners of the green spaces are irrigated, some water will be sprinkled on the road surface, which not only ...

AI Technical Summary

Problems solved by technology

When ordinary sprinklers are used to sprinkle water on these non-circular green spaces, in order to ensure that all corners of the green spaces are irrigated, some water will be sprinkled on the road surface, which not only affects passers-by, but more importantly, wastes water resources; Otherwise, there will be no water sprinkled on the corners of some green spaces

At present, there are also studies on sprinkler devices that use electronically controlled sprinkling shapes, but this device requires an external power supply, is costly, difficult to maintain, and inconvenient for workers to operate. It has not been promoted in practice.

The publication number is: CN1903446A "Adjustable pressure sprinkling device" discloses a sprinkling device that can adjust the pressure, but the structure of the device is relatively complicated, the cost is high, and it is not conducive to popularization and use.
