This water dropper utilizes the elastic reaction of elastic packing pipe to consume energy to the irrigation water in the gap entered between drip irrigation pipe, elastic packing pipe, and the pressure of the irrigation water that this water dropper is oozed meets the requirements.Gap between the through hole that the water outlet of this water dropper is passed through and drip irrigation pipe, elastic packing pipe is all the structural design not easily causing blocking, when not water outlet, elastic packing pipe plays the sealing function for drip irrigation pipe, therefore, a kind of drip irrigation system water dropper described in the utility model has stronger anti-blockage capability, make the hydraulic performance of this water dropper higher, effectively extend the service life of drip irrigation system.
The drip irrigation pipe of a kind of drip irrigation system water dropper of the present utility model, end socket, elastic packing pipe all belong to the parts that manufacturing process is simple, cost is low, make this water dropper entirety possess the advantage that manufacturing process is simple, cost is low.
Confirm through test, the performances such as the uniformity of the irrigation water that drip irrigation system water dropper described in the utility model oozes all meet national standard requirement.
As optimization of the present utility model, described water dropper also comprises external package pipe, the cross sectional shape of drip irrigation pipe, elastic packing pipe, external package pipe is identical, the inside and outside closely socket of elastic packing pipe, external package pipe, the first hole of coaxial line, the second hole is comprised in external package pipe, first hole is near end socket, and the diameter in the first hole is greater than the diameter in the second hole.
The external package pipe arranged has good protective effect to elastic packing pipe; In external package pipe, the diameter in the first hole is greater than the diameter in the second hole, and the body being convenient to elastic sealing element, in the deformation that evagination occurs near that side of end socket, is convenient to the outflow of irrigation water.
As optimization of the present utility model, there is the positioning table of evagination in the body stage casing of described elastic packing pipe, tube chamber stage casing in external package pipe to have between the first hole, the second hole and with the 3rd hole of the first hole, the second hole coaxial line, the diameter in the 3rd hole is greater than the diameter in the first hole, and positioning table is placed in the 3rd hole adaptedly.
3rd hole, positioning table adaptation coordinate, and like this, can be played the effect of axial location elastic packing pipe by external package pipe.
As optimization of the present utility model, the body of described drip irrigation pipe is located between through hole and end socket also have the annular effluent trough be exposed to outside elastic packing pipe, external package pipe.
The setting of annular effluent trough, for irrigation water provides a specific and orderly flow pass, like this, is more conducive to improving stability when drip irrigation system is poured water and uniformity.
As further optimization of the present utility model, the material of described drip irrigation pipe is polythene material, the body of drip irrigation pipe has the through hole of two coaxial lines near end socket place; The material of end socket is pvc material; The material of elastic packing pipe is silastic material; The material of external package pipe is pvc material; The length of elastic packing pipe, external package pipe is identical.
Only comprise drip irrigation pipe, end socket, elastic packing pipe, these four parts of external package pipe in this water dropper, and the material of described four parts is the respective material that price is comparatively cheap, makes the cost of manufacture of this water dropper lower; This water dropper can be made the series of products (namely allow the length of elastic packing pipe, external package pipe different) of different size, like this, according to the concrete needs of drip irrigation system Construction control and drip irrigation, can select this water dropper of different size flexibly.
