Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 6, a kind of pressure compensation drop with self-cleaning function described in the utility model
Head, it is main to include with lower component：
Water dropper body 1：Plastic material, any plastics such as polyethylene, polypropylene, ABS, PA all can, be connected outer wall with 2
Sealing, top ultrasonic bonding sealing.
Water dropper shell body 2：Plastic material, any plastics such as polyethylene, polypropylene, ABS, PA all can, with 1 be connected in
Wall seals, top ultrasonic bonding sealing.
Rubber pressure compensating diaphragm 3：All any rubber of elastomeric material such as silica gel, butyronitrile, PET can, have
Certain toughness between water inlet and delivery port, prevents water from directly flowing to outlet from import, for controlling with elasticity
The flow of the adjusted water outlet of volume of water chamber, the change being pressurized with front form the elastic deformation of rule.
Water inlet 4：It is connected with pipeline, the entrance that water enters, oral area distribution filter window stops that the impurity more than its orifice enters,
The size for filtering window is less than A size.
Delivery port 5：It is arranged on water dropper body 1.
Energy dissipating runner water inlet 6；
Energy dissipating runner delivery port 7；
Triangle energy dissipating obstacle array 8：Current are hindered to pass through so that water flowing becomes turbulent flow by laminar flow, and consumes
The efficiency of water energy, makes its pressure progressively diminish
Energy dissipating passage 9：Serve as water stream channel.
Operation principle of the present utility model is as follows：
The installation punching installation pressure-compensating water dropper on irrigation pipeline, pipeline tapping is than one section of straight body position on water inlet 4
Diameter is small, and water inlet 4 is inserted inside road pipeline, while the external diameter of the straight body position in one section of the top of water inlet 4 and duct wall are mutually close
Envelope, conical section are inserted inside road pipeline and catch on inner-walls of duct, prevent water dropper from coming off.Irrigation water is by the filter window on water inlet 4
A filtering part than entering inside after the big impurity of filter window size, have pressure irrigation water (the usual 50KPa~400KPa of pressure) by
Deformed upon in there is pressure to open the top of rubber pressure compensating diaphragm 3, spatial flow of the irrigation water from the deformation of rubber pressure compensating diaphragm 3
Enter energy dissipating runner water inlet 6, there is pressure irrigation water to be flowed out by flowing to delivery port 7 by energy dissipating after energy dissipating passage 9, finally by water outlet
Mouth 5 flows to crop root or is drained to crop structure area by other equipment.
Pressure compensation of the present utility model is mainly made up of two parts.
Referring to Fig. 7 and Fig. 8, Part I is energy dissipating passage 9, and some triangle energy dissipatings are provided with the energy dissipating passage 9
Obstacle array 8 forms, and ABCDEFR is critical size, and usual F is less than or equal to 0, and pressure water enters energy dissipating passage 9, is initially layer
Stream, run into and produce obstruction after triangle energy dissipating obstacle array 8 in the flow direction of fluid, it is impossible to smooth-going outflow and become turbulent flow, and
The bottom of triangle produces whirlpool, and the turbulent flow and whirlpool are avoided that the precipitation of impurity or nutrient solution in passage, plays from clear
Clean effect.
ABD sizes, and triangle energy dissipating obstacle display 8 are designed for the flow design demand under same nominal pressure
Number of triangles on same length channel reaches the demand of different flow.
Part II is compensation cavity volume regulation caused by the elastic deformation of the rule of rubber pressure compensating diaphragm 3.
When intake pressure change is big, the deformation quantity of rubber pressure compensating diaphragm 3 is big, is directly contacted when maximum with water outlet Cavity surface,
The cavity volume of rubber pressure compensating diaphragm 3 and delivery port is minimum, and irrigation water groove 12 flows out, as shown in Figure 5.
When intake pressure change is small, the deformation quantity of rubber pressure compensating diaphragm 3 diminishes, rubber pressure compensating diaphragm 3 and water outlet
The cavity volume of mouth becomes big, as shown in Figure 4.
The combination of the two regulation parts has just reached in certain pressure limit (50KPa~5KPa) dripping end flow
It is constant, play pressure compensation.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
