Description
Technical field：
The utility model is related to a kind of delivery hose more particularly to a kind of water delivery of agricultural irrigation automatic control flow are soft
Pipe.
Background technology：
In agricultural irrigation, delivery hose is a kind of equipment often used, its terminal as irrigation system, several
It is ubiquitous, during carrying out watering production operation to farming kind, require to need constantly to change delivery hose according to irrigating
Flow.The tube wall of existing delivery hose is largely made of three-decker, including outer plastic layer, middle layer and interior plastic cement
Layer, middle layer are arranged in the centre of outer plastic layer and interior plastic layer, and the surface of outer plastic layer is that there are the smooth circles for knitting landing net line
Cylinder needs to use water delivery since need the place of watering operation and diesel engine water pump assembly puts place there is always distance
Hose is attached sprinkling irrigation, and the irrigation amount in the set time is determined by the water flow of delivery hose, existing sprinkling irrigation flow control
It is all made of control valve or the control water-bound of complexity, flow control valve is set on delivery hose or control water-bound must the company of using
Connector is installed, and cost of parts is not only increased, and cumbersome for installation, installation effectiveness is low, and joint because sealing problem be easy
The phenomenon that causing leak.Existing delivery hose can not automatic control flow or can only use control valve control flow, installation
Maintenance replacement cost is high.
Utility model content：
In order to overcome existing delivery hose above shortcomings, the purpose of this utility model to be to provide one kind and automatically control
The delivery hose of flow, it, can be according to hydraulic pressure automatic control flow, installation simple in structure without adding complicated flow control valve
It is convenient to use, it is of low cost.
The technical scheme adopted by the utility model is that：
A kind of delivery hose of automatic control flow, it is characterized in that：Including tube body and controller perturbation circle, tube body includes outer modeling
Glue-line, middle layer and interior plastic layer, middle layer is arranged in the centre of outer plastic layer and interior plastic layer, in the outer snare of outer plastic layer
Equipped with controller perturbation circle, the coefficient of elasticity of controller perturbation circle is more than the coefficient of elasticity of tube body, and the pipe of controller perturbation circle part is housed
Internal diameter under body normality is less than the internal diameter of tube body other parts.
Further, equidistant spacer sleeve is equipped with six to ten controller perturbation circles outside tube body.
Further, the controller perturbation circle is elastic Cowhells.
Further, the controller perturbation circle includes elastic outer layer, spring and elastic inner layer, and spring is vertically set on outside elasticity
Between layer and elastic inner layer.
Further, under the controller perturbation circle normality inner ring diameter be tube body inner ring diameter a quarter to three/
Two.
Further, the outer surface of tube body is provided with wear-resisting convex body.
Further, the wear-resisting convex body of the outer surface of the tube body is the strip convex body being axially arranged along tube body, and and water delivery
Hose axis is parallel, and is uniformly distributed along the circumferential direction of tube body.
Further, the protrusion height of the wear-resisting convex body is 0.5~3 millimeter, the angle between adjacent two strip convex bodys
It is 15 °~180 °.
Further, the cross sectional shape of the wear-resisting convex body is semicircle, trapezoidal or rectangle.
Further, the wear-resisting convex body is the blocky convex body of point, is evenly distributed on the outer surface of the outer plastic layer of delivery hose
On.
Further, the protrusion height for putting blocky convex body is 0.5~3 millimeter.
The application method of the utility model：By controller perturbation circle fix suit just on tube body, controller perturbation circle not by
Inner ring diameter is less than the inner ring diameter of tube body in the case of pressure, and when sprinkling irrigation, injection pressure water source in tube body, hydraulic pressure controls elasticity
System circle struts, to change the water flow in tube body, controller perturbation circle control the inner diameter size of tube body according to the variation of hydraulic pressure and
Automatic to change, different hydraulic pressure makes the diameter of controller perturbation circle different, to different by the water flow of tube body.
Due to being set with controller perturbation circle outside the tube body of delivery hose, the coefficient of elasticity of controller perturbation circle is more than tube body
Coefficient of elasticity, the pipe diameter for being set with controller perturbation circle follows the diameter of controller perturbation circle to change and change, when needing to adjust
When irrigation water flow, pumping for water pump pressure only need to be adjusted, when intake pressure is more than discharge pressure, controller perturbation circle is by water
Pressure struts to increase the water flow of tube body, until discharge pressure is equal to intake pressure；When intake pressure is less than discharge pressure,
Controller perturbation circle is returned to due to natural resiliency restoring force so that discharge pressure is equal to intake pressure.In the outer surface of outer plastic layer
It goes up and is provided with wear-resisting convex body, to reduce the contact area of whole delivery hose and ground, in actual use, when need
When drawing tube body, only wear-resisting convex body is contacted with ground, reduces trail drag force, and the labour for considerably reducing operator is strong
Degree, what delivery hose was worn first is wear-resisting convex body, and the pressure-bearing tube wall of delivery hose is unaffected, to improve delivery hose
Service life.Meanwhile the setting of wear-resisting convex body improves the bearing capacity and tensile strength of delivery hose.
The utility model is simple in structure without adding complicated flow control valve, easy to use, not only saves a large amount of raw
Production, repair, installation cost, and the set-up time is greatly reduced, improve the sprinkling efficiency.Wear-resistant surplus increases 0.5~3 milli
Rice, service life can extend 2 years~3 years；Trail drag force reduces 50%~70%, and the labour for greatly alleviating operator is strong
Degree；Tensile strength and bearing strength improve 15%~30%, are verified through actual use, the utility model and prior art phase
Than：With wear-resistant, easily pulling, bearing strength, tensile strength height, service life is grown and the characteristics of can automatically adjusting carrying capacity.
