Abstract
The utility model provides a kind of pressure compensating emitter, described water dropper includes the mouth of a river, delivery port, and be communicated with the runner of described water inlet and described delivery port, be provided with resistance tooth and resistant block in described runner, and described resistant block is near described water inlet side, when overpressure increases, resistance tooth and resistant block effectively can make low water velocities, and runner can ensure the stability of water dropper water yield.
Description
Technical field
The utility model belongs to drip irrigation emitter technical field, particularly relates to a kind of pressure compensating emitter.
Background technology
Water-saving irrigation is the major measure that countries in the world developing modern agriculture is taked, drip irrigation is the high standard irrigation technique of a kind of advanced person in water-saving irrigation, and wherein the advantage such as the efficient and environmental protection of drip irrigation pipe most water-saving and yield-increasing is widely used in land for growing field crops, booth, ecological garden and urban afforestation.
At present, conventional pressure compensating emitter mainly contains pipe above formula and internally-inlaid two kinds, and it can ensure the good water outlet uniformity within the scope of pressure compensation.But existing pressure-compensating water dropper is the area of passage changing water dropper carries out adjustment pressure, and when area of passage diminishes, some impurity particles in water, just not by water dropper, cause water dropper to block.
Utility model content
The utility model provides a kind of pressure compensating emitter, and described water dropper includes the mouth of a river, delivery port, and is communicated with the runner of described water inlet and described delivery port, is provided with resistance tooth and resistant block in described runner, and described resistant block is near described water inlet side.
As the preferred scheme of the utility model, the central part of described runner has a groove, and described resistance tooth and resistant block are positioned at described groove.
As the preferred scheme of the utility model, the cross section of described resistance tooth is triangle.
As the preferred scheme of the utility model, be symmetrically arranged with two groups of resistance tooth groups in described groove, often group comprises some resistance teeth, and the some resistance teeth often organized in resistance tooth group are fixed together and are placed in groove, or each resistance tooth is placed on separately in groove.
As the scheme that the utility model is more preferably, the resistance tooth often organizing resistance tooth group tilts to the direction of water inlet successively, successively decreases in angle of inclination.This kind of design can reach and make resistance tooth have efficient recovery former state when hydraulic pressure in water dropper reduces and by the object of resistant block pushed home.
As the preferred scheme of the utility model, the material of described resistance tooth and resistant block is elastomeric material, and described elastomeric material is silicon rubber or EP rubbers.
The advantage that the utility model has and good effect are: when overpressure increases, and resistance tooth and resistant block effectively can make low water velocities, and runner can ensure the stability of water dropper water yield.

In figure: 1, water inlet; 2, runner; 3, resistance tooth; 4, resistant block; 5, delivery port; 6, back fence; 7, upper casing.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
Fig. 1 is a kind of preferred embodiment of the present utility model.
This water dropper includes the mouth of a river 1, the runner 2 of delivery port 5 and profile of tooth, and the middle part of runner 2 has a rectangular recess 8, and groove 8 is placed with resistance tooth 3 and resistant block 4.
Resistance tooth 3 has 12, and cross section is triangle, and 6 is one group, is symmetrical arranged, and 6 the resistance teeth 3 often organized can be placed on separately in groove 8, are placed in groove 8 after also can being fixed together in advance again; Resistant block 4 is placed near water inlet 1 side, and contact with resistance tooth 3 and place, the shape of resistant block 4 does not have special restriction, is preferably the shape of cuboid-type or one end sphere as shown in Figure 1.In the present embodiment, the material of resistance tooth 3 and resistant block 4 is elastomeric material, direction from resistance tooth 3 to water inlet 1 tilt and angle (α as shown in Figure 1) successively decrease gradually.
This water dropper also comprises upper casing 7 and back fence 6, and the size of runner 2 conforms to upper casing 7, and back fence 6 is positioned at the back of water dropper, and communicates with water inlet 1.
The course of work of the present utility model is: when inner pipe water pressure increases, and flow action, on resistant block 4, makes it extrude flexible resistance tooth 3, thus plays the effect reducing water velocity; When hydraulic pressure reduces, resistance tooth 3 can restore to the original state and by resistant block pushed home.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
