Structure and curved line trangle spacing structure connect to be formed, and curved line trangle structure includes triangle crown, and curl trapezium structure includes
Concave bottom of the tooth, the triangle crown of the first tooth type structures is corresponding with the concave bottom of the tooth of the second tooth type structures, and to same direction
Runner is convexed to form, the tooth foot of concave bottom of the tooth both sides is arc structure.
Further, the facewidth a of flow passage structure is 0.7-1.0mm, and bottom of the tooth is 0.8-1.2mm away from b, and the high h of tooth is 0.8-
1.0mm。
Further, the length of runner is 2-3.8cm.
Further, radius R1, R of arc structure2For 1/2~1/4 of bottom of the tooth away from b, and arc structure does not split bottom of the tooth
Away from b.
The beneficial effects of the utility model are compared with prior art：The flow passage structure conveyance capacity is strong, and effect of energy dissipation is good,
The anti-blockage capability of water dropper can be effectively improved, it is ensured that go out to flow stability, improve the uniformity of irrigation water appilcation of drip irrigation system.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of the flow passage structure of interior edge paster-type water dropper of the utility model.
Embodiment
The utility model is described in detail in shown each embodiment below in conjunction with the accompanying drawings, but it should explanation,
These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to these embodiment institute works
Energy, method or equivalent transformation or replacement in structure, belong within the scope of protection of the utility model.
Join shown in Fig. 1, the utility model provides a kind of flow passage structure of interior edge paster-type water dropper, and flow passage structure is along length
The section in direction includes the first tooth type structures 1 and the second tooth type structures 2, and the first tooth type structures and the second tooth type structures are by multiple songs
Side trapezium structure and curved line trangle spacing structure connect to be formed, and curved line trangle structure includes triangle crown 3, and curl is trapezoidal
Structure includes concave bottom of the tooth 4, and the triangle crown 3 of the first tooth type structures is corresponding with the concave bottom of the tooth 4 of the second tooth type structures, and
Runner 5 is convexed to form to same direction, the tooth foot 6 of 4 both sides of concave bottom of the tooth is arc structure.
Emitter flow channel uses circular arc turbulent flow runner design, on the one hand, when irrigation advance is through triangle crown, flow-shape by
Laminar flow becomes turbulent flow, and the mutual blending of fluid particle, movement is unordered, and many small whirlpools are formed in flow field, and effect of energy dissipation is notable,
While energy dissipating, the small vortex of generation can also sweep along the little particle impurity in water, prevent accumulation of impurities from blocking runner；The opposing party
Face, when turbulent current flow through round-arced tooth foot, can reduce the turbulent fluctuation of flow velocity and current, it is ensured that overcurrent is unobstructed, to subtract
The area of current low regime and stagnant area at few tooth foot, prevents microbial growth and little particle impurity from assembling at tooth foot, causes
Emitter clogging.
The utility model is described in further detail below.
The flow passage structure form and structural parameters of water dropper directly influence its effect of energy dissipation and performance of anti-blockage, the present embodiment
The flow passage structure of offer is a kind of circular arc turbulent flow runner, which is a kind of runner being combined by convex triangle and trapezoidal groove
Structure, and handled in trapezoidal groove bottom using fillet, to ensure the effect of energy dissipation of water dropper and overcurrent stability.
The performance of water dropper is also closely related with the structural parameters of runner in addition to being influenced by flow passage structure form.Water dropper passes through
The parameters such as facewidth a, space width l, tooth angle beta, the high h of tooth, flow channel length L can determine that the citation form of flow passage structure, and each structure
Parameter is again interrelated：Facewidth a and bottom of the tooth determine the size of space width l away from b；Facewidth a and the high h of tooth determine tooth angle beta；Tooth
Wide a, bottom of the tooth have together decided on width of flow path w away from b and the high h of tooth；So facewidth a, bottom of the tooth is away from three that the b and high h of tooth is flow passage structure
Key element.To ensure the effect of energy dissipation of water dropper and performance of anti-blockage, every structural parameters of water dropper have certain threshold value, according to meter
The threshold value that experimental result determines each structural parameters is simulated and surveyed to calculation machine：The facewidth a of water dropper is:0.7-1.0mm；Bottom of the tooth is away from b
For:0.8-1.2mm；The high h of tooth is：0.8-1.0mm.
The flow channel length of water dropper does not influence its planar structure, and little to fluidised form exponential effect, but when flow channel length is too short,
The triangle double wedge of distribution is few, influences its effect of energy dissipation；When runner is long, turbulent flow effect substantially subtracts when current flow through flow field end
It is weak, but also the possibility of runner blocking can be increased, so, flow channel length scope is usually set to：2-3.8cm.Tooth foot circular arc
Radius R1, R2It is set as 1/2~1/4 of bottom of the tooth away from b, and does not split with circular arc bottom of the tooth away from for the upper limit.
Emitter flow channel more reasonable structure provided in this embodiment, the performance of anti-blockage of water dropper and pouring water uniformly for drip irrigation system
Degree is high, and irrigation effect is good, specifically includes：
1) the circular arc turbulent flow runner uses the structure type that curved line trangle and curl trapezoidal groove are combined, and overcurrent is more logical
Freely, effect of energy dissipation is good, and anti-blockage capability is strong.
2) multiple energy dissipating is carried out when current flow through triangle crown, circular arc turbulent flow runner is passed through, overcurrent can be smoothed out, really
Protect out the uniform and stable property of stream.
3) round-arced tooth foot design can effectively reduce the area of current low regime and stagnant area at tooth foot, prevent microorganism
The aggregation with irrigation water small particles impurity is grown, improves water dropper performance of anti-blockage.By the structural parameters to runner into professional etiquette
Model, makes the more reasonable structure of water dropper, it is ensured that the performance of water dropper properties.
