Detailed description of the invention
The reciprocating drip irrigation emitter preventing blocking, comprises water dropper shell, water dropper water inlet 1, stainless steel wire 3, piston 4, switch lever 5, first spring 9, second spring 10, set screw 7, water dropper delivery port 6; Water dropper water inlet 1 is arranged on the upper end of water dropper shell, and water dropper delivery port 6 is arranged in the middle part of the side of water dropper shell; Relief chamber, water chamber, backwater cavity and piston control chamber is from top to bottom disposed with in water dropper shell; The upper end of relief chamber communicates with water dropper water inlet; The via hole of its lower end in the middle part of water chamber communicates with backwater cavity through rear; One end of water dropper delivery port 6 is arranged on backwater cavity upper surface and communicates with backwater cavity; Its other end is arranged on the sidewall of water chamber and communicates with outside; The spring base of the second spring 10 is arranged on piston 4 upper surface, and switch lever 5 is arranged in backwater cavity, and its lower end is arranged in spring base, and its upper end is used for the opening and closing of water dropper delivery port 6; Stainless steel wire 3 is arranged in the via hole in the middle part of water chamber, and its upper end is free end and stretches into relief chamber, and piston 4 is fixed in its lower end; Piston 4 can move up and down in water dropper shell; First spring 9 is arranged between piston 4 lower end and water dropper shell lower end inside face.Rubber seal is provided with between piston 4 and water dropper shell.Water dropper shell is cylindrical.Set screw is for regulating the elastic force of the first spring
Utility model works principle:
Switch lever can move back and forth with piston 4, and blocks delivery port in water dropper water inlet 1 when top dead centre.Piston 4 blocks delivery port in water dropper water inlet 1 when top dead centre, the water entered by water inlet promotes piston and moves downward, when moving to the outside thrust (pressure of the water of the area × water dropper of the interior delivery port of water inlet) of water that switch lever is subject to and being less than the downward thrust of the first spring, switch cover opens delivery port in outlet pipe because the energy storage of the first spring can move down rapidly.
Because delivery port in delivery port is much larger than water inlet, piston 4 can move up with the outflow of water due to the effect of the second spring 10.Owing to there being air to exist in design reasons water dropper all the time, switch lever can block the interior delivery port of outlet pipe, makes piston constantly reciprocating under the pressure of water.
Stainless pin is reciprocating in the pore of water inlet with piston, foreign material, sand etc. is pushed away water inlet, to avoid blocking into water.
