WATER OUTLET FOR IRRIGATION PIPELINE OF DROP IRRIGATION SYSTEMS

摘要

FIELD: agricultural engineering, in particular, amelioration technique, more particular, drop irrigation systems.;SUBSTANCE: water outlet has valve made in the form of elastoplastic member located in lower part of irrigation pipeline. Conical locking needle positioned on elastoplastic member is fixed above water outlet opening provided through irrigation pipeline wall. Elastoplastic member has widened portion positioned above locking needle and running along circle of diameter exceeding that of water outlet opening by 3-3.5 times. Water outlet opening is made in the form of taper pipe with taper angle of 10-15 deg. Length of elastoplastic member from supporting plane to axis of water outlet opening is 1.6-1.8 the inner diameter of pipeline.;EFFECT: increased efficiency by providing regulation of water flow rate depending on pressure in pipeline, increased yield and reduced irrigation norm.;2 dwg
