Abstract
Provided is a turbulence flow type inter-pipe dripper. The turbulence flow type inter-pipe dripper comprises a dripper cavity, a flow channel in the cavity, a flow channel water inlet and a water outlet, and is characterized in that the flow channel is formed by multi-segment turbulence flow-type flow channels arranged on the inner walls of two sides of the cavity, and laminar flow channels arranged between the turbulence flow type flow channels on two sides. A spiral flow channel surrounding the cavity is formed in the dripper cavity. According to the utility model, the turbulence flow-type flow channels and straight laminar flow channels are connected to form a longer flow channel, so the inter-pipe dripper has a better anti-blocking function.
Description
Technical field:
The utility model belongs to a kind of water-saving irrigation product, particularly water dropper between a kind of turbulent flow type pipe that is applicable to use in the fields such as heliogreenhouse, factory farming cultivating facility, vertical planting.
Background technology:
At present, the runner that is applied in water dropper in the fields such as heliogreenhouse, factory farming cultivating facility, vertical planting mainly adopts turbulent flow type runner and straight laminar flow runner.The liquid particle of laminar flow runner is to flow with mode parallel and that do not mix and form.The liquid particle of turbulent flow type runner is with disorderly orbiting motion, and between particle, collision mutually, forms turbulent fluidised form.
Summary of the invention:
The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art, and provide water dropper between a kind of turbulent flow type pipe, this water dropper is connected turbulent flow type runner with straight this runner of two types of laminar flow runner, form longer runner, and have better anti-blockage function.
As above design, the technical solution of the utility model is: water dropper between a kind of turbulent flow type pipe, comprise runner, runner water inlet and delivery port in water dropper cavity, cavity, it is characterized in that: the runner in described water dropper cavity is made up of the laminar flow runner between the multistage turbulent flow type runner on the inwall of cavity both sides and turbulent flow type road, both sides stream, is linked to be a helical flow path around cavity in water dropper cavity.
The groove that is shaped with the multiple sieve apertures of a band before above-mentioned runner water inlet, water inlet is communicated with sieve aperture.
Above-mentioned runner water inlet is communicated to sieve aperture by water dropper inwall.
Above-mentioned runner has plural water inlet.
The angular bulge loop of above-mentioned runner water outlet system.
On above-mentioned water dropper cavity, be shaped with the anti-skidding barb of slip-off preventing.
The sectional area of above-mentioned sieve aperture is less than the sectional area of runner.
The utlity model has following advantage and good effect:
1, runner design of the present utility model is that multistage turbulent flow type runner and straight runner are alternate, is linked to be a helical flow path around water dropper.Bending turbulent flow type runner section, had both lengthened the length of unit distance runner, and the current that can make again turbulent fluidised form constantly punching touch flow path wall, and the impurity in anti-sealing rests in runner, and laminar flow runner section can be accelerated current, has increased anti-blockage function.Therefore, runner of the present utility model had both improved slow pressure and the pressure stabilization function of runner, had improved again anti-blockage function.
2, the groove that is shaped with the multiple sieve apertures of a band before the utility model runner water inlet, water dropper water inlet is communicated with sieve aperture, has improved anti-clogging performance.
3, the utility model runner has plural water inlet to be communicated with the sieve aperture on groove, further increases anti-clogging performance.
4, the utility model runner water outlet has increased the prominent ring of a wedge angle, and object is when after water-supply-pipe and water dropper grafting, prevents that hydraulic pressure is by water-supply-pipe slippage, has improved stability and the security of work.
5, the utility model can be dismantled at any time, clean.
Brief description of the drawings:
Fig. 1 is side view of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is rearview of the present utility model.
Detailed description of the invention:
As shown in the figure: water dropper between a kind of turbulent flow type pipe, the runner in water dropper cavity is made up of the laminar flow runner 3 between the multistage turbulent flow type runner 2 on cavity both sides inwall 5 and turbulent flow type road, both sides stream, is linked to be a helical flow path around cavity in water dropper cavity.The groove that is shaped with the multiple sieve apertures 6 of a band before above-mentioned runner water inlet 4, the sectional area of sieve aperture is less than the sectional area of runner, and water inlet is communicated with sieve aperture by water dropper inwall.The angular bulge loop 9 of above-mentioned runner delivery port 8 place's system.On above-mentioned water dropper cavity, be shaped with the anti-skidding barb 1,7 of slip-off preventing.Above-mentioned runner has plural water inlet.
Two ends of the present utility model can connect water delivery hollow billet (PE flexible pipe or PVC flexible pipe) and form formula drip irrigation pipe between pipe.Because the operating pressure of this drip irrigation pipe is very low, by can moving from gravity of water, therefore also referred to as gravity type drip irrigation pipe, water dropper is also referred to as gravity type water dropper.
The internal diameter of hollow billet need match with the columniform external diameter of water dropper, coordinates the runner that forms water dropper with water dropper.The inside of water dropper is a cylindrical hole, and water can be from centre through flowing to next water dropper, until the end of drip irrigation pipe.Current, when through water dropper, enter emitter flow channel by several sieve apertures on water dropper inwall and between water dropper water inlet groove.Runner is around water dropper, from the spiral delivery port that is threaded to water dropper middle part in one end of water dropper.Water in the time of the passing through of each section of turbulent flow type runner and laminar-flow type runner loss the pressure of water inlet, slowly flow out drip irrigation pipe at water outlet with water droplet or thread shape.
When water passes through between turbulent flow type runner alternate with each other and laminar-flow type runner, be subject to the resistance that frictional force and flow passage structure cause, consume most of energy, thereby make the water yield of outflow limited, therefore the water passing in water dropper has kept relatively more pressure and flow, supplies with next until more water dropper.
In rational length (by the permission length of measuring and drip irrigation pipe waterpower is calculated), the hydraulic pressure pad value of each water dropper position, within forming the drip irrigation water yield uniformity scope allowing, is the connecting length of drip irrigation pipe permission.Meanwhile, the connecting length that in unit length, the quantity (spacing of water dropper) of water dropper also allows drip irrigation pipe impacts.Water dropper is more, and flow is larger, and the pressure loss is also just more, and water dropper flux depression is also just more.Water consumes energy more in runner, and water dropper flow is less, and the drip irrigation uniformity is higher, allows lay length just longer.Therefore the effect of emitter flow channel energy dissipating becomes drip irrigation pipe performance important indicator, and the anti-clogging performance of drip irrigation pipe is also good drip irrigation pipe speciality simultaneously.
The design of water dropper between this novel turbulent flow type pipe, from runner characteristic and multinomial anti-blockage function, has all promoted performance and the quality of drip irrigation pipe greatly.
