Abstract
The utility model relates to a pressure-compensated drip-irrigating nozzle which comprises a nozzle base, a nozzle body and a pressure compensating film, wherein the nozzle base and the pressure compensating film are connected in a jack mode, the nozzle base and the nozzle body are connected by a snap ring, and the control over the flow rate is realized between the pressure compensating film and the nozzle body through the different installing angles of a positioning pin. The utility model adopts split design and has the advantages of easy disassembly, blockage prevention and convenient realization of the control over the flow rate.
Description
The utility model belongs to the high-efficiency water-saving irrigation rig, particularly a kind of controllable pressure-compensated drip irrigation emitter.
The long runner of currently known water dropper utilization is realized the reduction of hydraulic pressure, thereby realizes the purpose of design of drip irrigation.But because the water dropper size is little, form long runner, it is long-pending just must to reduce cross section of fluid channel, and a subject matter that causes is exactly that the water dropper anti-blockage capability is poor, causes that easily water dropper lost efficacy.In addition, known water dropper is suitable for firm discharge, when the changes in flow rate scope is big, is far from suitable when using in China rural area especially, for the popularization of high-efficiency water-saving agricultural affects.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of quick detachable, anti-clogging is provided, can have conveniently realized the drip irrigation emitter to the adjusting of flow.
For achieving the above object, solution of the present utility model is that it comprises: water dropper seat, water dropper body and be arranged on the water dropper seat and the water dropper body between the pressure compensation diaphragm, the water dropper seat is provided with clip, the water dropper body is provided with snap ring, and the water dropper seat links to each other with clip by snap ring with the water dropper body.
Water dropper seat of the present utility model is provided with connecting pin, and the pressure compensation diaphragm is provided with jack, and the connecting pin on the water dropper seat inserts in the jack of pressure compensation diaphragm.
Water dropper body of the present utility model is provided with the flow gear, and the pressure compensation diaphragm is provided with decides the body pin, and the alignment pin of pressure compensation diaphragm is aimed at the different flow gear of water dropper seat.
Be provided with the pressure compensation chamber between water dropper seat of the present utility model and the pressure compensation diaphragm.
Be provided with energy dissipating step and eddy current generation tooth in the water dropper body of the present utility model.
Be provided with conflux energy dissipating chamber and drip nozzle boss in the water dropper body of the present utility model.
The utility model adopts the split design, can conveniently realize dismounting and installs, thereby can the impurity of deposition be cleaned, with advancing by the setting angle of flow gear conveniently to realize adjusting to flow.
Fig. 1 is a main cutaway view of the present utility model.
Fig. 2 is an A-A cutaway view of the present utility model.
Fig. 3 is a B-B cutaway view of the present utility model.
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to accompanying drawing 1,2.Connecting pin (17) on the water dropper seat 1 of the present utility model inserts in the jack 18 of pressure compensation diaphragm 4, the different flow gear 14 that alignment pin 16 on the pressure compensation diaphragm 4 is aimed on the water dropper seat 1, thereby realize control to flow, water dropper seat 1 links to each other with clip 13 by snap ring 12 with water dropper body 15, to realize easily detachable purpose.
Referring to accompanying drawing 1,2.Operation principle of the present utility model is achieved in that at first water enters pressure compensation chamber 2 through water dropper seat 1, flow through pressure compensation diaphragm 4 through aperture 3 and enter runner 5, in runner 5, produce eddy current through energy dissipating step 6 and eddy current generation tooth 7, enter the energy dissipating chamber 8 of confluxing after reducing head, owing to compile in opposite directions after current flow through drip nozzle boss 9 from both sides, thereby further decompression reduces water velocity, and the cascading water hole 10 that the water that final flow rate is very low covers drip nozzle boss 9 enters drip nozzle 11.Pressure compensation of the present utility model chamber 2 and runner 5 are divided into two independent sectors by pressure compensation diaphragm 4, by the selection of 5 different setting angles realizations of pressure compensation diaphragm 4 and runner to different flow, the heavy in section labyrinth path by Computational Fluid Dynamic Analysis is adopted in the design of runner 5, produce eddy current, when effectively reducing head, prevented the obstruction to drip nozzle such as impurity in the water; Can effectively prevent the obstruction to drip nozzle such as impurity at the drip nozzle boss 9 of runner 5 and drip nozzle district design,, thereby can the impurity that the boss place deposits be cleaned because water dropper seat 1 and water dropper body 15 realize dismounting easily by snap ring 12 and clip 13 and install.
