Embodiment
It is further to the utility model below in conjunction with the accompanying drawings in order to be able to be more clearly understood that the technical solution of the utility model
Explanation.
As shown in figure 1, a kind of pressure compensating emitter, water dropper is generally by shell 1, inner core 2, flexible sheet 3, water inlet
4 and delivery port 5 constitute, flexible sheet 3 is sandwiched between shell 1 and inner core 2, existing certain activity space, but also with relative
Stability, can so avoid water dropper in compensating coefficient and rinse the phenomenon that has big difference of state flow.
Shell 1 is made up of shell upper casing 1a and shell lower casing 1b, is provided with screw thread and is closely connected, water dropper is turned on, side
Just cleaning.
Flexible sheet 3 is anticorrosive pressure compensation flexible silicon film.It is the regulation chamber of inner core 2 on diaphragm, in pressure
The lower elastic membrane of effect presses to intracavitary, and intracavitary is become as outlet passage.When water dropper is in compensating coefficient, flexible sheet and regulation chamber
Between runner change with the change of pressure, pressure increase when, runner section reduce；When pressure reduces, runner section increases
Greatly, so that the outflow of water dropper keeps stable；When pressure it is small to a certain extent when, water dropper just enter flushing state, elastic membrane
Original state is just completely recovered to, outlet passage becomes very big, and flow also accordingly increases.
As shown in Fig. 2 the installation connection of pressure compensating emitter.Water or chemical fertilizer flow through socket joint bypath valve by PE pipes 8
9, it can adjust total water current size；The quantity and spacing of the pressure compensating emitter 10 of connection are set on demand, and each water dropper has pressure benefit
Repay, export water dropper current stabilization；Plug 11 is set in current terminal, the irrigation Precision Irrigation of plant 12 is given with this.Water dropper 10 is from valve 9
More remote, the pressure for entering water dropper 10 from water inlet 4 is just smaller, due to the effect of flexible sheet 3, pressure is got over hour, and circulation is disconnected
Face is bigger, so that the outflow of water dropper keeps stable.The utility model has the compensation characteristic of ultra-wide, and compensation range is 10-40
Rice.
Water inlet 4 is provided with inlet flange 6, is the jut in inlet wall, when the pressure of water dropper porch is less than 0
When, flexible sheet 3 will be pressed on flange 6, completely close runner, therefore when there is negative pressure in pipe, diaphragm self-return is blocked
Water inlet 5, prevents any material because negative pressure is inhaled into runner, so this water dropper can be used for sub-irrigation；Water inlet is set
There is hangnail 7, debris enters water dropper when anti-locking system starts.
Delivery port 5 can be socketed 4mm pipes, can be embedded in underground or be placed in surface, facilitate EXIT POINT to be accurately positioned.Work as crop water
When amount increases with crop growth stage, the quantity of water dropper 10 can be increased and wanted so as to increase water dropper density to meet the water demand of crop
Ask." cobweb formula " installation can be carried out, drip irrigation output is diverted into several water droppers exports.
Shell 1 is provided with 10 kinds of colored color codes and is easy to difference, and 10 kinds of flows are available, and different flow is set to different face
Color.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent claim
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent claim.
