Изобретение относитс  к области гидравлических машин, в частности к средствам снижени  величины ударного давлени  в водоводах оросительных машин.The invention relates to the field of hydraulic machines, in particular, to means of reducing the magnitude of shock pressure in the conduits of irrigation machines.

Известен способ иредотврашени  гидравлического удара в водоводах с запорной арматурой посредством прерывистого ее закрыти , включаюшего чередование циклов закрыти  и остановки 1.There is a known method for rendering hydraulic impact in conduits with shut-off valves by intermittently closing it, including the alternation of closing and stopping cycles 1.

Недостатком известного способа  вл етс  возможность возникновени  увеличенных ударных давлений вследствие наложени  возмущаюш.ей волны ударного давлени  с ударной волной в отводах, в частности, дождевальной машины.The disadvantage of this method is the possibility of increased shock pressure due to the application of a perturbed shock pressure wave with a shock wave in the outlets, in particular, of a sprinkler.

Целью изобретени   вл етс  повышение эффективности гашени  гидравлического удара.The aim of the invention is to increase the efficiency of hydraulic shock absorption.

Дл  этого по предлагаемому способу цикл прерывистого закрыти  выбирают равным времени пробега ударной волны в водороде.For this, according to the proposed method, the cycle of intermittent closing is chosen equal to the running time of the shock wave in hydrogen.

При цикле прерывистого закрыти  запорной арматуры, установленной в водоводе , равном времени пробега в нем ударной волны, происходит интерференци  ударных волн повышенного и пониженного давлени , что резко снижает ударное давление в водоводе.When the cycle of intermittent closure of valves installed in the conduit is equal to the travel time of the shock wave in it, the interference of the shock waves of high and low pressure occurs, which dramatically reduces the shock pressure in the conduit.
