Technical field
The present invention relates to a kind of fluidics sprinkler signal nozzle water intaking method for determining position.
Background technology
Fluidics sprinkler makes shower nozzle side not have air to fill into mainly through the water intaking of signal nozzle in the course of the work, thus makes the left and right sides of shower nozzle form pressure reduction, promotes shower nozzle and complete rotary motion after causing the attached wall of power stream.Through retrieval, patented claim relevant at present has: fluidics sprinkler, application number: 03222424.9; Wall-attachment fluidic sprinkler, application number: 200710134562.5; In these patents, fluidics sprinkler signal nozzle water intaking position determines that it whether can one of the key factor completing rotary work.Only describe the course of work of fluidics sprinkler in prior art, but not yet consider this technical matters of determination of fluidics sprinkler signal nozzle water intaking position.
Mainly through the water intaking position of experience adjustments fluidics sprinkler signal nozzle in current research, whether enough signal water yields are received to shower nozzle and completes rotary work and observe.Thus whether the water intaking position of signal nozzle is suitable when accurately cannot know that fluidics sprinkler works.If when some in particular cases causes fluidics sprinkler can not complete rotary work, just can not analyze it whether because the inappropriate reason in signal nozzle water intaking position causes, thus effectively cannot solve problems.Therefore, the present invention proposes a kind of fluidics sprinkler signal nozzle water intaking method for determining position, to determine that fluidics sprinkler in the course of the work, ensure that whether its signal nozzle water intaking position is correct.
Summary of the invention
In order to ensure the correctness of fluidics sprinkler signal nozzle water intaking position in the course of the work, the invention provides a kind of fluidics sprinkler signal nozzle water intaking method for determining position, signal nozzle can be inserted the correct position in the fluidic body of fluidics sprinkler by staff efficiently according to the method.
The starting point of the inventive method is: first, according to prior designing requirement, determines the inner parameter of the guarantee fluidics sprinkler signal nozzle tram in fluidic body under normal operation.Then, on the basis ensureing the inner parameter under the state of tram, push away easily at the external parameter that fluidics sprinkler outside can more easily measure according to these inner parameters are counter, thus indirectly ensure the tram of signal nozzle in fluidic body by whether these external parameters of external measurement are up to standard.
Given this, content of the present invention is: a kind of fluidics sprinkler signal nozzle water intaking method for determining position, comprises following steps:

obtain; Using n as external parameter fiducial value, when judging that whether the water intaking position of signal nozzle is correct, by actual measurement n, the calculated value of the actual measured value of n and n is carried out matching ratio comparatively.
In such scheme, by actual measurement n, by the process that the actual measured value of n and the calculated value of n carry out mating be: if the calculated value of the actual measured value of n and n is consistent, then illustrate that fluidics sprinkler signal nozzle water intaking position is correct, if the calculated value of the actual measured value of n and n is inconsistent, then fluidics sprinkler signal nozzle water intaking malposition is described.
In such scheme, the intersection that the outer side surface of signal nozzle is crossing with the outer side surface of fluidic body is no more than 0.1mm to the deviation between the calculated value and actual measured value of the distance n of signal nozzle 1 upper end.
Technique effect of the present invention: utilize fluidics sprinkler signal nozzle of the present invention fetch water method for determining position can quick test fluidics sprinkler signal nozzle water intaking position whether correct, can ensure in the fluidics sprinkler course of work to the strong control of its signal nozzle placement location.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fluidics sprinkler signal nozzle water intaking position.
In figure, 1. signal nozzle, 2. fluidic body, 3. basic circle hole.
Embodiment
The invention provides a kind of fluidics sprinkler signal nozzle water intaking method for determining position.For above and other objects of the present invention, feature and advantage can be become apparent, cited below particularly go out preferred embodiment, and coordinate institute's accompanying drawings, be described below in detail.
As shown in Figure 1, the first step, determines the inner parameter of fluidics sprinkler signal nozzle tram in fluidic body; First, have chosen 10PXH type fluidics sprinkler is metrical prototype, choose to the length of signal nozzle 1 should planting model
lfor 18mm; The diameter of signal nozzle 1
dfor 4mm; Signal nozzle 1 is toward the insertion angle of fluidic body 2
be 30
o; Using the center line in fluidics sprinkler basic circle hole 3 as Y-axis, with the intersection point O of the plane at Y-axis and endpiece place, basic circle hole 3 for initial point sets up coordinate system, determine with the point of intersection of the center line of signal nozzle 1 and signal nozzle 1 bottom end face for reference point P, according to the designing requirement to 10PXH type fluidics sprinkler, when fluidics sprinkler normally works signal nozzle 1 fetch water position reference point P distance Y-axis distance
a=2.5mm.
Second step, being converted into by the inner parameter of the above-mentioned first step can in fluidics sprinkler outside than required indirect parameter when being easier to the external parameter of measurement; Measure the distance of Y-axis and fluidic body 2 outer side surface
rfor 8mm, obtaining signal nozzle 1 toward the laterally inserted degree of depth of fluidic body 2 is
s=8-2.5=5.5mm., can easily determine thus, the centerline length w that signal nozzle 1 is inserted into fluidic body 2 inside is w=s/sin
=11mm.
3rd step, calculates the calculated value of the outer side surface of signal nozzle 1 intersection crossing with the outer side surface of fluidic body 2 to the distance n of signal nozzle 1 upper end, by formula n=m+
d/ 2tg
=10.46mm, therefore in actual mechanical process, we are with the measured value of the outer side surface of rule measuring-signal mouth 1 intersection crossing with the outer side surface of fluidic body 2 to the distance n of signal nozzle 1 upper end, mate with the calculated value of n again, whether meet when can determine that fluidics sprinkler normally works
athe ideal conditions of=2.5mm.
In addition, in practical application, generally we define the error between the measured value of a n and calculated value, as long as its deviation is no more than 0.1mm, all affects less, be considered as the normal range of operation of fluidics sprinkler to the normal range of operation of fluidics sprinkler.
Although the present invention discloses as above with preferred embodiment; so itself and be not used to limit the present invention; any those skilled in the art; without departing from the spirit and scope of the present invention; when being used for a variety of modifications and variations, therefore protection scope of the present invention is when being as the criterion depending on the appended right person of defining.
