Description
Technical field
The utility model relates to a kind of reciprocating drip irrigation emitter.
Background technology
The mode of current domestic common drip irrigation emitter many employings tubular type decompression current limliting, the mode etc. of labyrinth type turbulent flow flow channel type decompression current limliting.But aforesaid way complex structure, maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of reciprocating drip irrigation emitter, solves existing drip irrigation emitter complex structure, the technical problem that maintenance is inconvenient.
Technical solution of the present utility model:
A kind of reciprocating drip irrigation emitter, comprises water dropper shell, water dropper water inlet, piston, switch lever, the first spring, the second spring, water dropper delivery port;
Above-mentioned water dropper water inlet is arranged on the upper end of water dropper shell, and above-mentioned water dropper delivery port 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 above-mentioned water dropper shell;
The upper end of above-mentioned 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 above-mentioned water dropper delivery port 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 above-mentioned second spring is arranged on piston upper surface, and described switch lever 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;
Above-mentioned piston can move up and down in water dropper shell; Above-mentioned first spring is arranged between piston and water dropper shell lower end inside face;
Rubber seal is provided with between above-mentioned piston and water dropper shell.
Above-mentioned water dropper shell is cylindrical.
The parameter of above-mentioned first spring is determined in the following manner: the outside thrust of the water that switch lever is subject to is less than the downward thrust of the first spring.
Above-mentioned delivery port diameter is much larger than water inlet.
The advantage that the utility model has is:
The utility model is the same with the water dropper mounting means originally used, without the need to special material and technology, can extensive use agricultural irrigation, plant equipment long-term low flow velocity lubricating system (changing water into lubricating oil) etc.

Fig. 1 is structure and the position view of the utility model hull-borne;
Fig. 2 is the structure and the position view that enter retaining state after the utility model draining;
Reference numeral: 1-water dropper water inlet, 2-reduces pressure water inlet; 4-piston, 5-switch lever, 6-water dropper delivery port, 8-cushion rubber, 9-first spring, 10-second spring.
Embodiment
A kind of reciprocating drip irrigation emitter, comprises water dropper shell, water dropper water inlet 1, piston 4, switch lever 5, first spring 9, second spring 10, 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 1; 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 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; Piston 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.
Utility model works principle:
Switch lever can 5 to move back and forth with piston 4, and blocks delivery port in water dropper water inlet 6 when top dead centre.Piston 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 9 can move down rapidly.
Because delivery port in delivery port is much larger than water inlet, piston 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 4 constantly reciprocating under the pressure of water.
