Description
Technical field
The present invention relates to the technical fields of water-saving irrigation, and in particular to a kind of flow adjustable pressure compensation type emitter.
Technical background
Currently, Hills plantation irrigation has three: first is that Hills are with a varied topography, the gradient is big, irrigating system
Pressure of uniting is uneven, and the uniformity that causes to pour water is poor；Second is that irrigation water is based on surface water, it is miscellaneous containing solid particle, microorganism etc.
Matter, emitter clogging are very serious；Third is that crop is different in the water requirement of different growing stage, it is therefore desirable to which different flow is poured water
Device.Douche, which changes flow, in the prior art can only replace douche.Therefore it develops a kind of suitable for Hills plantation irrigation
Douche become urgent problem to be solved.
Application No. is 201610532350.1 patents of invention: a kind of anti-clogging pressure of the uniform self-regulated of rate of discharge
Douche is compensated, the flow of this douche includes pedestal, shell, and pressure compensation gasket and metering needle, pressure compensation gasket are
For realizing pressure compensation, and the change of flow is realized by replacing the metering needle of different thicknesses.It is this to pour water
Although device can be realized pressure compensation, but adjustable to flow is not very effectively that the flow adjustment range of realization is small, Bu Nengshi
The fast and reliable adjusting of existing a variety of metered flows.
Summary of the invention
Aiming at the problems and shortcomings existing in the prior art, the purpose of the present invention is to provide a kind of uniformity of irrigation water appilcation
High, capable of washing, the adjustable pressure-compensated douche of flow of blocking, the filling especially suitable for crops such as Hills economic forests
It irrigates.
To achieve the goals above, the present invention takes following technical solution: a kind of flow adjustable pressure is compensation
Douche, including upper cover, pressure compensation gasket and lower seat, the upper cover are removably connect with lower seat；Under described
Seat is equipped with douche water inlet and filter screen；The upper cover is equipped with water outlet；The upper cover inner bottom surface setting assists out
Water flow passage；Energy eliminating ring is equipped in the douche, the Energy eliminating ring is located in the cavity formed between upper cover and lower seat, disappears
Energy ring is mounted in the inner cavity of upper cover, and the outer surface of Energy eliminating ring and the inner cavity surface of upper cover match；The pressure-compensated gasket
It is divided into two chambers on the staircase structural model of the inner cavity of Energy eliminating ring, and by the cavity formed between upper cover and lower seat；Described disappears
Energy ring outer wall is equipped with labyrinth flow-path；The lower seat chamber that one end of the labyrinth flow-path and lower seat and pressure compensation gasket are formed connects
Logical, the other end is connected with the upper cover chamber that pressure compensation gasket and upper cover are formed.
The Energy eliminating ring outer wall surface is circular conical surface.
The pressure compensation gasket is a flexible disk.
The present invention is due to using the above structure, and 1, by pressure compensation, make to remain in water supply pipe despite pressure fluctuations
Guarantee flow；2, since upper cover is removably connect with lower seat, it can be convenient dismounting in blocking, clean runner, in addition
Due to the Energy eliminating ring using split, labyrinth flow-path is arranged on Energy eliminating ring, so can install not when needing different flow
With the Energy eliminating ring of flow.

Specific embodiment
In order to more clearly explain technical solution of the present invention, it is further elaborated now in conjunction with embodiment.
Referring to Fig. 1, the present embodiment provides a kind of flow adjustable pressure compensation type emitter, this kind of flow adjustable pressure compensation
Formula douche, including upper cover 1, Energy eliminating ring 2, pressure compensation gasket 3 and lower seat 4, the upper cover 1 and lower seat 4 are connected by screw thread
It connects, upper cover 1 and lower seat 4 form in cavity and be equipped with Energy eliminating ring 2 and pressure-compensated gasket 3, and pressure-compensated gasket 3, which is located at, to disappear
On the staircase structural model 10 of the inner cavity of energy ring 2, and the cavity formed between upper cover 1 and lower seat 4 is divided into two chambers.
Fig. 2 gives the structure sectional view of this kind of flow adjustable pressure compensation type emitter upper cover, and upper cover 1 is equipped with water outlet
7；1 inner bottom surface of upper cover setting auxiliary outlet passage 8.
Fig. 3 gives the structure sectional view of seat under this kind of flow adjustable pressure compensation type emitter, and lower seat 4 is equipped with douche
Water inlet 5 and filter screen 6.
Fig. 4 gives the structural schematic diagram of this kind of flow adjustable pressure compensation type emitter Energy eliminating ring, and Energy eliminating ring 2 is mounted on
In the inner cavity of upper cover 1, the outer surface of Energy eliminating ring 2 and the inner cavity surface of upper cover 1 match；2 outer surface of Energy eliminating ring is equipped with labyrinth flow-path
8；The labyrinth water inlet 9 of labyrinth flow-path 8 is connected to the upper cover chamber that upper cover 1 and pressure compensation gasket 3 are formed, and other end labyrinth goes out
The mouth of a river 11 is connected with the lower seat chamber that pressure compensation gasket 3 and lower seat 4 are formed；The outer surface of Energy eliminating ring 2 is circular conical surface, and taper is
2°。
The water inlet that water flows through lower seat enters lower seat chamber, enters labyrinth flow-path by labyrinth water inlet on Energy eliminating ring, through labyrinth
Enter upper cover chamber from labyrinth water outlet after runner energy dissipating, finally flows out water dropper from the water outlet of upper cover.The length of labyrinth flow-path and
Width can change the flow for entering upper cover chamber under certain pressure, therefore, replace the Energy eliminating ring of different size labyrinth flow-path, so that it may
To change the flow of water dropper.When pipeline pressure increases, pressure-compensated gasket is discharged water section of making a slip of the tongue to upper cover Direction distortion
Area becomes smaller, so that regulating dropping head flow, guarantees in certain pressure limit, dripping end flow is stablized, and improves uniformity of pouring water.
Upper cover inner bottom surface setting auxiliary outlet passage is the minimum in order to guarantee the douche when pressure-compensated gasket deforms maximum
Flow.
The foregoing describe basic principles and main features of the invention.It should be understood by those skilled in the art that of the invention
It is not restricted to the described embodiments, the above embodiments and description only illustrate the principle of the present invention, is not departing from
Under the premise of the scope of the invention, various changes and improvements may be made to the invention, these changes and improvements both fall within claimed
