Description

Metering valve
Technical field
The present invention relates to a kind of metering valve for measuring liquid state or paste medium.Control quantitatively in this regard, particularly the volume of respective dosage.At present, normally controlled by the video on the time point of quantitative pumped (conveying) medium.But for valve manufacture producer, on valve, importantly just control the amount of discharging.
Summary of the invention
Therefore object of the present invention is, provides a kind of metering valve, and this metering valve is applicable to control each single dosage institute and wants metered media quantitative also therefore this metering valve is reliable especially.
This object is by having the metering valve of feature described in claim 1 and being particularly achieved thus, the valve housing of i.e. metering valve installed the photoelectricity fence that intersects with the stroke dripped of discharging from valve nozzle and have evaluation equipment, this evaluation equipment carries out evaluation by the total degree changed of detection photoelectricity fence transmission to the signal of photoelectricity fence.Therefore not only between the two states, namely distinguish between noiseless and noisy transmission, but consider the degree of transmission amount change.In this regard, photoelectricity fence is particularly formed like this, and make the amount of transmission also not reduce to zero when dripping process, the light therefore sent by photoelectricity fence at least partially all the time arrives the receiving element of photoelectricity fence.
According to the present invention, can be distinguished between the dripping of non-metering and flowing by photoelectricity fence.Quantitative stability also can be controlled.Tool is advantageous in this regard, the optical conductor existed by photoelectricity fence with when needing formed one respective drip through light curtain.Light curtain preferably has and drips the size coordinated.Drip (bar) and there is the diameter of nozzle and length depends on the opening time.
The advantageous further formation of tool is from the feature of dependent claims.

Embodiment
The embodiment of the metering valve 1 shown in Fig. 1 has nozzle 2 in one side, and this nozzle is suitable for opening and closing in a defined manner, drips 3 to discharge.But replace that drip also can the post of shaping liquid state and paste medium or bar.The side of metering valve 1 is arranged like this transmitter 4 and the receiver 5 of photoelectricity fence 4,5, dripping that the light of injection is discharged 3 is passed through.
As can be seen from the cross section of Fig. 2, the transmitter of photoelectricity fence can have transmitter LED7 for generation light and be that conduction and deflection can have optical conductor 6.Particularly optical conductor 6 is for such utilizing emitted light, make the nozzle of light and metering valve at a certain distance with discharge from nozzle drip stroke intersect, thus drop in such as encounter surface before pass through light beam.Advantageously, photoelectricity fence and valve leave certain distance and install.
On the face that metering valve is contrary with transmitter, the light of transmitting hits optical conductor 6 and the receiving sensor 8 that turns to and lead.Then receiving sensor 6 can send corresponding signal by tie cable, and the transmission that this signal description light is detected is also such as shown in figure 4 – 6.
The transmitter of photoelectricity fence and receiver can be surrounded by shell 10.Whole region must be cleaned out.Glass surface 14 is more applicable than the surface of optoelectronic component 7,8 for this reason.Optical conductor 6 utilizes the size of its size 11,12 also shaping smooth curtain 13, particularly as seeing in the metering valve be shown specifically from Fig. 3.
The width 11 of light curtain 13 roughly has the size identical with column diameter 18.Advantageously slightly wider, then the position of light curtain 13 need not be so accurate.Height 12 suitable little – are about 1mm and less.Temporal resolution also can also identify very little dripping very well thus.Surface 14,15 and 16 is optically transparent.Face 16 can overarch as lens.Face 17 delustring also can blacking.
Nozzle diameter 18 pages determines the diameter of the dripping of liquid state or paste medium, bar or post, and this medium is discharged with efflux velocity 19 from nozzle when valve lift 20 carries out.Given size also can for determining that volume takes in thus.
Signal and Valve controlling jointly mark and compare with this Valve controlling.Fig. 4 illustrates the signal that the signal of Valve controlling and transmission are obtained by photoelectricity fence jointly in the graph.Two signal posts with on axle for the moment, thus can temporally between read output signal connect each other.
For valve signal, zero line 21 means valve closing.The line 22 interrupted shows the valve opened.Therefore interval during this is valve lift 20.For the amount of photoelectricity fence transmission, the line 23 of interruption is equivalent to glitch-free transmissive state.Line 24 such as dripping or post of discharging from valve, shows that photoelectricity fence is subject to that drip-dry disturbs, but but the transmission existed due to post width.
In Fig. 4, temporal process is as follows.On time point 25, valve starts to open, thus drips or post can be discharged, and on time point 26, first time is recorded by photoelectricity fence, because its arrives the upper limb of light curtain, and causes the amount of transmission to reduce.27 time, reach the maximum interference of transmission, because to drip or the starting point of post arrives the lower edge of light curtain.After the regular hour, valve is closed again (28).If after this to drip or the terminal of post arrives the upper limb (29) of light curtain, so the transmission of photoelectricity fence increases again, until terminal finally arrives the lower edge of light curtain and leaves its (30), thus transmission is again noiseless.
The particularly edge steepness 31 of valve opening as can be seen from Figure 4.The curve 23 of the amount citing of photoelectricity fence transmission is equivalent to the curve of specified.In this regard, the edge 33 of this transmission curve obtains and drips or the information of post efflux velocity.
Illustrate in figs. 5 and 6 with the example of the curve different distributions of specified.Do not measure the unlatching lift of valve as can be seen from Figure 5, in figure 6, the interference of transmission has another kind of shape.Speed, weaken with the time all different.Certainly there is interference.
