With new specific protection domain.
With reference to the accompanying drawing of specification, by being further described to specific embodiment of the present utility model, make
The technical solution of the utility model and its advantage are clearer, clear and definite.It is to show to describe embodiment below with reference to accompanying drawing
Example property, it is intended to the utility model is explained, and it is not intended that to limitation of the present utility model.
Referring to shown in Fig. 1, Fig. 2 and Fig. 3, the utility model embodiment provides a kind of solution water dropper for drip irrigation, including
Open housing 1, and spiral-lock is in the cover plate 2 of the open-mouth of housing 1, specifically, the exterior bottom wall of housing 1 is provided with some reinforcements
Muscle, improve the intensity of housing.
Cover plate 2 is in the arcuate structure of evagination, and storage chamber 22, the both sides phase of the bottom surface of cover plate 2 are provided with the middle part of the bottom surface of cover plate 2
To being provided with apopore 21, connected between storage chamber 22 and two apopores 21 by labyrinth flow-path 23, and labyrinth flow-path 23
The height of flow path wall 24 is gradually successively decreased from the middle part of cover plate 2 to the both sides of cover plate 2.
The inner horizontal of housing 1 is provided with elastomeric isolation film 3, specifically, elastomeric isolation film 3 is TPU waterproofing membranes.The elasticity
The middle part of barrier film 3 is provided with through hole 31；Specifically, through hole 31 is located at the lower section of storage chamber 22.In use, elastomeric isolation film 3
According to the size of hydraulic pressure can different degrees of projection upward, and because each height of flow path wall 24 is gradually successively decreased, therefore according to elasticity
The degree of convexity of barrier film 3, it is in contact with corresponding flow path wall 24, ensure that the operating efficiency of labyrinth flow-path 3.I.e. being capable of pin
Accurate formula regulation is carried out to hydraulic pressure, it is ensured that the stability of water dropper water yield.
The bottom wall both sides of housing 1 are relatively set with inlet opening 11.Current in pipeline are entered by two inlet openings 11 respectively
Enter housing 1, then converged again to centre, storage chamber 22 is entered by through hole 31., can phase during being converged among current direction
Energy is mutually offset, is preconditioned equivalent to the hydraulic pressure to current, it is ensured that the stability of water dropper water yield.
Shown in Figure 4, the top surface of cover plate 2 is provided with copper sheet 25 around the position of apopore 21.The copper sheet can be in water dropper
Copper ion is discharged during use, the root system for suppressing plant grows to apopore, prevents water outlet hole plug.
It is shown in Figure 5, grid 12 is provided with inlet opening 11.It can prevent the impurity in pipeline from entering housing 1.Enter one
Step, the aperture of grid 12 is more than the diameter of through hole 31.I.e. elastomeric isolation film 3 also can further be filtered to current, be prevented
Only the impurity in housing enters labyrinth flow-path 23.
The operation principle of solution water dropper that the utility model is used for drip irrigation is：
In use, the current in pipeline enter housing 1 by two inlet openings 11 respectively, then converge, lead to centre again
Cross through hole 31 and enter storage chamber 22.During being converged among current direction, can cancel out each other energy, equivalent to the water to current
Pressure is preconditioned, it is ensured that the stability of water dropper water yield.
After current enter housing 1, elastomeric isolation film 3 according to the size of hydraulic pressure can different degrees of projection upward, and
Because each height of flow path wall 24 is gradually successively decreased, therefore according to the degree of convexity of elastomeric isolation film 3, it connects with corresponding flow path wall 24
Touch.Such as：
Shown in Figure 2, when not having current or minimum water flow pressure in housing 1, shape does not occur for elastomeric isolation film 3
Become, the flow in storage chamber 22 and labyrinth flow-path 23 is larger.
When the water flow pressure in housing 1 is stepped up, elastomeric isolation film 3 is gradually raised upward, and according to pressure
Size progressively by being in contact with the both sides flow path wall 24 of cover plate 2, is developed into and is in contact with the middle part flow path wall 24 of cover plate 2.Now, water storage
Flow in chamber 22 and labyrinth flow-path 23 progressively reduces.
Shown in Figure 3, when water flow pressure reaches the upper limit in housing 1, elastomeric isolation film 3 is raised fully up, and with
All flow path walls 24 are in contact, and now, the flow in storage chamber 22 and labyrinth flow-path 23 is minimum.
Current enter after storage chamber 22 flow to corresponding apopore 21 by independent labyrinth flow-path 23, improves water dropper
Drop amount.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, the utility model
Above-mentioned embodiment is not limited to, it is equal using the improvement and replacement of techniques well known on the basis of the utility model
Fall in the scope of protection of the utility model, it should be limited by each claim.
