Abstract
The utility model relates to an anti-clogging constant flow drip irrigation control head, which mainly comprises a water reservoir, a float, an inlet switch and main pipe connectors fixedly connected with reservoir; the reservoir is provided with inlet holes and weep holes, as well as a float therein; the end of the connecting rod of the float is fixed connected with the inlet switch arranged in the main pipe connectors. The utility model has a reasonable design, low cost and long service life; furthermore, as a result of a liquid level control of the reservoir through the float, the water yield of the drip irrigation is not easy to affect by the water pressure of the main pipe, therefore ensuring a constant outflow under varying water pressure. The liquid level of the reservoir is close to the outlet, resulting in a low water pressure, and further, a larger opening of the outlet at a same water yield, so as to prevent the outlet from clogging. The utility model can not only save the water, but also provides great benefits to plants and greening in the hilly, hillside and arid desert regions.
Description
Affiliated technical field
The utility model relates to the drip irrigation control head, what relate generally to is a kind of anti-stifled constant current drip irrigation control head.
Background technology
Drip irrigation technique is the indispensable a kind of irrigation form of novel agricultural, and it has not only saved a large amount of irrigation water, and it also provides necessary life condition for the growth of plant in complex-terrain and arid area.The core of drip irrigation technique is exactly the flow of each drip irrigation of control, and flow too conference causes face of land moisture content to run off, and too little can the causing again of flow irrigated deficiency.Existing drip irrigation all adopts the mode of orifice restriction to realize basically, promptly opens an aperture at female water pipe in the localities through what need to irrigate, makes water drop by drop ooze out through the throttling of small holes, and this method and technology is simple, cost is low.But it has disadvantages such as easy fouling, obstruction, flow be wayward, and it stops up just more serious when particularly it being used for sub-irrigation.Though the infiltrating irrigation head that utilizes the nanofiltration material to make has been arranged now,, this infiltrating irrigation head still can not solve and ooze out the constant adjustable difficult problem of the water yield.
Summary of the invention
The purpose of this utility model just produces thus, proposes a kind of anti-stifled constant current drip irrigation control head, and it not only can adjust the water yield easily, guarantees constant flow when water pressure fluctuations, is difficult for simultaneously stopping up, and oozing the water yield can be steady in a long-term.
For achieving the above object, the utility model is achieved through the following technical solutions: it mainly is made up of water receiver, float, water inlet switch and female pipe connections, water receiver is fixedlyed connected with female pipe connections, which is provided with inlet opening and weeper, float is arranged in the water receiver, fixedlys connected with the water inlet switch in being arranged on female pipe connections in the end of this float connecting rod.
The utility model is reasonable in design, and is simple in structure, cost is low, long service life, because it adopts the liquid level in the float control water receiver, so the hydraulic pressure in female pipe does not influence the water yield of drip irrigation, can guarantee that under the situation that intake pressure changes water yield is constant.Again because liquid level and apopore close proximity in the water receiver, so water pressure is very low, like this assurance during identical water yield apopore just can open very greatly, thereby avoided the easy clogging that causes because of apopore.In addition, just can be easy to change water yield as long as change the margin of apopore and liquid level, it is also very convenient therefore to adjust flow.Extensive use of the present utility model can not only be played comparatively ideal water-saving result, and plant and the greening for hills, hillside, drought desert area simultaneously also has immeasurable effect.
Description of drawings
The utility model accompanying drawing is a structural representation.
Among the figure, 1, float, 2, weeper, 3, water receiver, 4, the float connecting rod, 5, water inlet switch, 6, female pipe connections.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in the figure, present embodiment mainly is made up of water receiver 3, float 1 and female pipe connections 6, one end of female pipe connections 6 is connected with sending the jellyfish pipe, the other end is fixedlyed connected with water receiver 3, float 1 is arranged in the water receiver 3, and fixedlying connected with the water inlet switch 5 in being arranged on female pipe connections 6 in the end of its float connecting rod 4, is provided with weeper 2 and relief hole on water receiver 3, weeper 2 is arranged on the below of water receiver 3, and it can be provided with one or more as required.Present embodiment in use, the water of being sent here by female pipe enters in the water receiver 3 through female pipe connections 6.A part of water wherein flows out from weeper 2, because intake pressure is greater than discharge pressure, so water outlet makes water level constantly rise less than water inlet, when water level is raised to certain position, float 1 floats under buoyancy function, driving water inlet switchs 5 by float connecting rod 4 makes into water close, water inlet stops, because water outlet is continuously to carry out, at this moment the water level in the water receiver will constantly descend, float will drive water inlet switch 5 again and open water intaking valve 1 to water receiver 3 moisturizings, again reach balance until liquid level, this process constantly repeats, thereby guarantee still to guarantee under the situation that weeper 2 constantly there are flowing out the level stability in the water receiver, the stable level in the water receiver has guaranteed again that conversely the water yield that apopore flows out is stable, because the water level in the water receiver is very low, so hydraulic pressure is very little, even the aperture of apopore can guarantee that more also water yield is very little.
The utility model also can adopt pressoreceptor to substitute float, thereby makes it not limited by directionality.This hydraulic coupling receptor is at hydraulic pressure during greater than a certain setting value, and distortion also drives water valve and closes into water, thereby guarantees the constant pressure in the drip head.
