Specific embodiment
The present invention is described in further detail for the embodiment provided below in conjunction with attached drawing.Described embodiment packet
The various details for helping to understand are included, but they can only be counted as illustratively, be a part of the embodiments of the present invention, and
The embodiment being not all of.Unless otherwise defined, the technical term or scientific term used herein is should be belonging to the present invention
The ordinary meaning that personage in field with general technical ability is understood.Meanwhile in order to keep specification more clear succinct, will omit
Pair it is well known that function and construction detailed description.
As shown in Figs. 1-5, a kind of uniform performance testing device of spray head splash, including several water storage tanks 2, each water storage tank 2
Bottom end connection setting flow tube 3, the water outlet lower section of the flow tube 3 are equipped with measuring tank 4, and 4 bottom of measuring tank is equipped with and lets out
Discharge orifice 40, described 4 at least part of measuring tank are transparent material, and 4 side of measuring tank is equipped with scale 41.The water storage tank 2 is set to
Below the spray system test spray head of splash experimental rig.
The flow tube 3 is L-shaped structure, including horizontal flow tube 31 and vertical flow tube 32, the horizontal flow tube 31
Arrival end be connected to the bottom of water storage tank 2, the outlet end of horizontal flow tube 31 passes through the entrance of bend pipe and vertical flow tube 32
End connection, the outlet end of vertical flow tube 32 are set to 4 top of measuring tank.
The outlet end of the horizontal flow tube 31 is equipped with L shape baffle 36.
The baffle 36 includes vertical baffle 361 and horizontal baffle 362, and the vertical baffle 361 is set to water storage tank 2 and erects
Between straight flow tube 32 and measuring tank 4, the horizontal baffle 362 is set to 4 top of vertical flow tube 32 and measuring tank.
The measuring tank 4 is square structure.
The water storage tank 2 is square structure.
Several water storage tanks 2 are separate structure, and several water storage tanks 2 are set side by side and are interconnected and fixed.Alternatively, described
Several water storage tanks 2 are whole long slot structure, be equipped in the long slot structure several partitions whole long slot structure is divided into it is several
Square grid.
According to the uniform performance testing device of spray head splash of the application, configuration aspects have been done for existing collecting system of water
Innovation, during the test, as long as the height of water level for reading in each lattice measuring tank after water drenching is stablized calculate it is each
The flow of a water pipe.For relatively existing splash experimental rig, metering is more accurate, and time-consuming seldom, and manpower consumption is also less.
It is simple and reasonable according to the uniform performance testing device of spray head splash of the application, it is easy to use, it is time saving and energy saving again
Save worry；Appearance is exquisite, reduces human error, and overall accuracy improves；It is easy installation and reliable, it integrally consolidates durable.
According to the uniform performance testing device of spray head splash of the application, for the vent flow of spray head, splash range and splash
Uniformity measurement.Testing major influence factors of the vent flow of spray head in test device is hydraulic pressure, so collecting system of water
Innovation it is influenced less.And have a significant impact for the test of splash range and splash uniformity.
The uniformity test of spray head is determined by measuring the uniformly distributed coefficient of spray head, and the uniformly distributed coefficient of spray head is from mathematics
It is exactly the mean square deviation that water is splashed down on each of water storage tank cell for angle.
The measuring tank 4 of square-section is arranged below in flow tube 3 below each 2 grid of water storage tank, also sets under measuring tank 4
Fixed-size aperture, that is, discharge orifice 40 lets out device under constituting, 4 side of measuring tank indicates scale 41, and convenient reading water level is high
Degree.The water that spray head splash is got off splashes to water storage tank, flows to measuring tank by the flow tube below grid, in measuring tank, because
For the effect of hydraulic pressure, water level can be stablized in certain height.During the test, after waiting waterflow stabilizations, as long as reading each
The design discharge coefficient of the scale of water level in measuring tank, the hydraulic pressure obtained according to level scale and metering device can be counted accurately
That calculates each water storage tank grid splashes down water flow.
Finally splashing down water flow and calculate the uniformly distributed coefficient of spray head according to each grid.On the other hand, splash range
Specific splash range then can be determined according to the size of grid according to the grid being intuitive to see under no water droplet.
According to the uniform performance testing device of spray head splash of the application, due to no longer needing manually to be measured using graduated cylinder
Take, be able to divide the square grid in water storage tank it is thinner, square section product be original square section accumulate four/
One, the collection mode precision for splashing down water being correspondingly connected to for each grid is higher.
It, can be by the examination of measuring tank 4 and water storage tank 2 and its top by the way that horizontal flow tube 31 and vertical flow tube 32 is arranged
It tests spray head to be staggered certain distance, the influence for avoiding measuring tank 4 from being sprayed water by test spray head, it is ensured that its water received is all from
In flow tube, to promote the accuracy of test, more accurate result is obtained.
By the way that baffle 36 is arranged, it is L-shaped baffle, baffle gear that one piece of section, which is housed, in the end for crossing overflow pipe horizontal direction
In the side and top surface of the close spray head of metering sink, measuring tank 4 is avoided to be prevented by the influence of test spray head direction water mist
The water of spray head splash further promotes the accuracy of test, obtains more to be entered in measuring tank by the mode except flow tube
Accurate result.
"upper" described herein, "lower" or " top ", " lower section " or similar term are the placement shapes with normal use
Relativeness for state, that is, the positional relationship that illustrations are substantially shown.When placement status changes, such as
When overturning, corresponding positional relationship should be also converted therewith to understand or implement the technical solution of the application.
