Abstract

The present invention relates to micro irrigation system, and is especially one kind of mesh filter. The mesh filter consists of sealing cover, barrel and filtering net inside the barrel. The barrel has main structure, water inlet pipe and water outlet pipe connected through threads to water pipe of the micro irrigation system; and the filtering net includes skeleton and screen on the skeleton. The present invention features the sealing cover connected through threads to the barrel and possessing top blowdown port; the integral streamline structure of the water inlet pipe, water outlet pipe and the barrel; and the concentric water inlet pipe and the water outlet pipe. The filter has small size, light weight, easy installation, streamline structure, high filtering efficiency, low water head loss and other advantages.

Description

technical field [0001] The invention relates to micro-irrigation system equipment, in particular to a novel screen filter. Background technique [0002] With the rapid development of my country's economy, the contradiction of relatively insufficient water resources has become increasingly prominent, and water conservation has become one of the primary tasks of various industries, especially for agriculture in arid and semi-arid areas, making full use of limited water resources to improve production It is a long and arduous task. [0003] The application of water-saving micro-irrigation technology provides an effective way to solve the contradiction of water shortage in agricultural production, and micro-irrigation equipment is the core of this technology. Since the outlet aperture of the emitter in the micro-irrigation system is generally very small, it is very easy to be blocked by dirt and impurities in the water source, so strict purification of irrigation water is an ess...
