Problems solved by technology

However, during the use of existing irrigation devices, there are certain requirements for the permitted use pressure of water supply. If the water pressure is too high, the impact force will easily cause damage to the internal structure of the irrigation device, thereby shortening the service life of the irrigation device.

Abstract

An irrigating device comprises a housing, a water inlet and a water outlet. A pressure limit valve communicated between the water inlet and the water outlet is arranged in the housing and composed of a valve body, a pressure ring, a valve spool, a diaphragm, springs and a valve bonnet. A nozzle is detachably mounted on the water outlet and provided with a water outlet passage communicated with the water outlet. The irrigating device further comprises a support. The head of the support is detachably sleeved to the nozzle, and a water diversion seat is detachably mounted on the tail of the support and provided with a first water diversion block opposite to the outlet of the nozzle. The irrigating device has the advantages that by the aid of the irrigating device, constant pressure can be realized effectively, damage of internal structure due to overhigh water pressure is prevented, and service life of the irrigating device is prolonged. Further, the irrigating device is easy to replace and convenient to use as the nozzle and the housing as well as the water diversion seat and the support are in detachable connection.

Description

technical field [0001] The invention relates to an irrigation device. Background technique [0002] For agriculture, forestry, and gardens, irrigation technology has been widely promoted. However, the existing irrigation device has certain requirements on the allowable pressure of water supply during use. If the water pressure is too high, its impact force will easily damage the internal structure of the irrigation device, thereby shortening the service life of the irrigation device. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides an irrigation device with a simple structure that can realize constant pressure. damage, prolonging its service life. [0004] The technical solution of the present invention to solve the technical problem is: an irrigation device, comprising a housing connected with a water pipe and having a cavity, two ends of the housing are provided with a water inlet ...
