Abstract
The invention belongs to a test device for testing the anti-blocking property and hydraulic property of a drip irrigation belt, which is particularly suitable for the anti-blocking test of the drip irrigation belt. The anti-blocking test device of the drip irrigation belt comprises a muddy water tank, a water distribution tank, a pipe, a valve and various pumps, wherein a booster pump is communicated with the upper end of the muddy water tank and a water distributor through a pipeline respectively; each water outlet of the water distributor is communicated with each drip irrigation belt hung on a test table through a pressure instrument and a pressure regulation valve respectively; the water distribution tank and the muddy water tank are communicated with the pipe through a pipe pump; the pipe is provided with a control valve; the water distribution tank is provided with a stirrer and a water inlet pipe; and a charging port is formed at the upper end of the water distribution tank. As the water distribution tank is arranged in front of the muddy water tank, in a test, muddy water is prepared in the water distribution tank in advance, then the muddy water is poured into the muddy water tank, and mud and water are mixed twice so that mud in the muddy water is uniformly dispersed and continuous operation of the test is ensured.
Description
Technical field
The invention belongs to the test unit of anti-property stopped up in test drip irrigation zone and hydraulic performance, be specially adapted to the anti-blocking test in drip irrigation zone.
Background technology
The anti-blocking test jar in traditional drip irrigation zone adopts a jar end helical stir system; Stirrer paddle receives a physical strength and jar restriction of interior hydraulic pressure, and jar interior deposition earth forms and revolves nest during the rotation, can't disperse fully; Cause a jar interior muddy water appearance to have the suspension difference all the time; Sediment charge about in jar is irregular, the dead angle problem that stirs occurred, fundamentally head it off.The patent No. is that ZL200920140016.7 discloses a kind of anti-blocking test device; It is employed in the first-class radian of same contour around the muddy water tank and is uniformly distributed with at least three ebullators are being set; The water delivering orifice of every ebullator and water inlet are communicated with the upper and lower end of muddy water jar respectively through upper hose; The pump discharge of each ebullator equates, closes heating arrangement is installed being positioned on every upper hose on the water delivering orifice of ebullator upper end deploying respectively; The water inlet of supercharge pump is communicated with muddy water jar lower end through rising pipe, and the water delivering orifice of supercharge pump is communicated with muddy water jar upper end and water trap respectively through the voltage supply pipe.Though this device has improved the water sand dispersed homogeneous degree of jar interior muddy water to a certain extent; But this device is owing to have only a muddy water jar; At the trial earlier need water and silt proportioning is good; Just can make an experiment, lack of water stops test and prepares muddy water in test is carried out may occurring in the process because of jar, and the anti-blocking test in drip irrigation zone was according to national standard requirements needs droplets 9 hours continuously; This suspends test with regard to having caused in the process of the test lack of water, thereby has influenced the continuity and the accuracy of test.
Summary of the invention
The object of the present invention is to provide a kind of nothing to stir the dead angle, water sand is uniformly dispersed and tests the anti-blocking test device in the drip irrigation zone that can carry out continuously.
The technical scheme of employing of the present invention is: the anti-blocking test device in this drip irrigation zone comprises water distribution jar, muddy water jar, pipeline, valve and various pump; Supercharge pump is communicated with muddy water jar lower end and water trap respectively through pipeline; Each water delivering orifice of water trap is suspended in each drip irrigation zone on the testing table through manometer and pressure regulator valve connection respectively; Water distribution jar and muddy water jar are communicated with through in-line pump and pipeline; Pipeline is provided with by-pass valve control, in the water distribution jar, is provided with stirrer and water inlet pipe, is provided with charge door in the upper end; Be uniformly distributed with at the first-class radian of same contour at least three ebullators are being set around the muddy water tank; The water delivering orifice of every ebullator and water inlet are communicated with the upper and lower end of muddy water jar respectively through upper hose; The pump discharge of each ebullator equates that the water inlet of supercharge pump is communicated with muddy water jar lower end through rising pipe.Earlier silt and water are prepared at the water distribution jar during use; Open to stir to take turns and mix; The by-pass valve control of opening the connecting tube of water distribution jar and muddy water jar afterwards injects the muddy water jar with water, and the ON cycle pump carries out muddy water, carries out the anti-blocking test of drip irrigation zone after circulation a period of time; In the process that anti-blocking test carries out synchronously the water distribution jar again the proportioning muddy water inject the muddy water jar, the carrying out continuously of warranty test.
The beneficial effect of the present invention's technology is before the muddy water jar, to be provided with the water distribution jar owing to having adopted; In the water distribution jar, carry out the muddy water preparation at the trial in advance; The muddy water jar that reinjects afterwards, silt and water be through twice mixing, makes silt in the muddy water be uniformly dispersed and warranty test carries out continuously.
Below in conjunction with accompanying drawing the present invention is described further.
