Description
Technical field
It the utility model is related to agricultural irrigation technology, more particularly to a kind of irrigation water dropper.
Background technology
In field of agricultural irrigation, it is often necessary to supply filtered moisture, fertilizer or other chemical agents to soil.Irrigate
Slow and constant current progress is needed, existing control method is the cooperation of lid and lower cover on setting, to control the perseverance for irrigating flow
Fixed, higher to technological requirement, structure is extremely complex, is extremely difficult to the requirement of constant current.
Utility model content
In view of this, the utility model provides a kind of irrigation water dropper, and the perseverance of fluid flow is controlled in itself by film
It is fixed, solve the complicated technical problem of existing constant current emitter structure.
The technological means that the utility model uses is as follows：A kind of irrigation water dropper, including upper lid and lower cover, it is described on be covered with
Inlet, liquid outlet is covered with described, film is installed between the upper lid and the lower cover, the film includes elastic portion
With plasticity portion, the film be located at below the inlet at be elastic portion, the upper and lower end face in the plasticity portion be respectively equipped with into
Liquid groove and go out liquid groove, the feed liquor groove and it is described go out liquid groove be interconnected, it is described go out liquid groove and the liquid outlet
Connection, the inlet bottom are provided with stop part, and the elastic portion passes through stop part described in upper and lower Deformation control and the elasticity
The size of fluid flow opening between portion.
Further, the stop part be located at inlet side end face it is oblique.
Further, the feed liquor groove and to go out liquid groove be labyrinth flow-path.
The beneficial effects of the utility model are that upper lid and lower cover need not set runner, need to only be set on film,
Its is simple in construction, reduces cost, and the gap between elastic portion and stop part is controlled by hydraulic pressure above and below the elastic portion of film
Size, to ensure the constant of fluid flow.
Brief description of the drawings
Fig. 1 is the utility model schematic cross-section；
Fig. 2 is the structural representation of film upper surface in the utility model.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As depicted in figs. 1 and 2, a kind of irrigation water dropper, including upper lid 1 and lower cover 2, upper lid 1 are provided with inlet 3, and lower cover 2 is set
There is liquid outlet 4, film 5 is installed between upper lid 1 and lower cover 2, film 5 includes elastic portion 6 and plasticity portion 7, and elastic portion 6 has bullet
Property, without elasticity, it is elastic portion 6 that film 5, which is located at the lower section of inlet 4, in plasticity portion 7, and the upper and lower end face in plasticity portion 7 is set respectively
There is feed liquor groove 8 and go out liquid groove 9, feed liquor groove 8 is interconnected with liquid groove 9 is gone out, and goes out liquid groove 9 and is connected with liquid outlet 4, is entered
The bottom of liquid mouth 3 is provided with stop part 10, and elastic portion 6 is opened by fluid flow between upper and lower Deformation control stop part 10 and elastic portion 9
The size of mouth.When liquid enters from inlet 3, in the presence of fluid pressure, the elastic portion 6 of film 5, elastic portion 6 are pressed downward
Deformation downwards, an opening is formed between elastic portion 6 and stop part 10, liquid flows into feed liquor groove 8 from opening, and liquid runs down is entered
Liquid groove 8 flows into out liquid groove 9, is finally flowed out from liquid outlet.When liquid at liquid outlet 4 reaches a certain amount of, at liquid outlet 4
Hydraulic pressure when being more than the hydraulic pressure at inlet 3, the elastic portion 6 of liquid up moulding piece 5, elastic portion 6 is moved upwards so that elasticity
Opening between portion 6 and stop part 10 reduces, and the flow flowed into from inlet 3 of liquid is reduced.Thus, controlled by hydraulic pressure
Gap length between elastic portion 71 and stop part 41, to ensure the constant of fluid flow, the utility model divides film 5 for bullet
Property portion 6 and plasticity portion 7, by feed liquor groove 8 and go out liquid groove 9 and be arranged in the plasticity portion 7 of film 7, on being provided in
On lid 1 and lower cover 2, the manufacturing cost of lid 1 and lower cover 2 can be effectively reduced, also, on the whole, the structure of water dropper
Become simple, reduce cost.
Further, stop part 10 be located at the side of inlet 3 end face it is oblique so that inlet 3 is more gently
Into in feed liquor groove 8.As shown in Fig. 2 feed liquor groove 8 and to go out liquid groove 9 be labyrinth flow-path, labyrinth flow-path passes through liquid
When be turbulent flow, the stability of fluid flow with energy dissipating, decompression, current stabilization, flushing, can be ensured.
In summary, using a kind of irrigation water dropper of the present utility model, elastic portion 71 and stop part are controlled by hydraulic pressure
Gap length between 41, to ensure the constant of fluid flow, the utility model divides film 5 for elastic portion 6 and plasticity portion 7,
By feed liquor groove 8 and go out liquid groove 9 and be arranged in the plasticity portion 7 of film 7, can without being provided on upper lid 1 and lower cover 2
With the manufacturing cost of lid 1 and lower cover 2 in effective reduction, also, on the whole, the structure of water dropper becomes simple, reduces
Cost.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc., the utility model should be included in
Within the scope of protection.
