Fig. 2 be interface valve and tested aerosol bottle by gauge head syndeton synoptic diagram.
Embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, family expenses aerosol commodity amount metering test device of the present utility model comprises density bottle 1, interface valve 2, pipeline, extraction valve 3, introduction valve 4, vacuum pump 5, rail plate 6, stepper motor 7, pressure unit 9 etc.
As shown in Figure 2, interface valve 2 is by connector 11, and O-ring seal 12 and pressure ring 13 are connected by gauge head 14 with tested aerosol bottle 8.
The propelling topworks that the utility model adopts a cover to be made up of rail plate and stepper motor realizes, and realizes that by computer control software robotization detects.
A) sensing range: 350ml;
B) it is consistent that the limits of error: ± 10.5ml(and JJF1070-2005 decide package goods net content metering test rule request).
The interface valve is connected key with density bottle with the nozzle of aerosol valve have 2 points, and the one, connect the back and in the aerosol transfer process, can not reveal, it two is that connected mode simply is convenient to operation.The present invention adopts structural member as shown in Figure 2.Namely be basic material with the stainless steel, the junction embeds copper material.Such benefit is that the rigidity of external member is not yielding, and embedded copper material pressure ring has soft characteristics again, is convenient to the nozzle plug.Aspect cooperation, because the nozzle material is the plastics rolled-up stocks, do not have clear and definite machining precision index, so we are that excessively (interference) cooperates with the interface processing request, utilization is flexible by the gauge head plastics, and when being sent by gauge head when firmly inserting pressure ring, plastics overcome elastic deformation and enter pressure ring, after reaching certain pretightning force, produced sealing function between gauge head and the pressure ring when just waiting.Another measure of taking of sealing is to embed O-ring seal in the interface bottom, and benefit is, the one, after inserting certain buffering is arranged, and its two nozzle plays sealing function bottom interface.The present actual two road sealing functions that play of interface that use.
We know, flowing of liquid influenced by potential, external force, pressure reduction nothing more than, and it is all inoperative to be transferred in the process of density bottle these extraneous factors at aerosol content.Because under 25 ℃ ± 3 ℃ conditions, the pressure in the aerosol container must not be greater than 1MPa, generally between 0.5～0.8 MPa in accordance with regulations.And density bottle is a container that is full of air seal, and air itself forms resistance, and when the two butt joint, liquid can not flow out on request, and also can not impose external force to aerosol container, forces to discharge content.
Utilize the pressure reduction principle in the utility model.A decompression, injecting systems have namely been designed.The negative pressure of vacuum pump and extraction valve control density bottle, at present design load be-90kPa～-95kPa, the content release of introduction valve control aerosol.Extraction valve and introduction valve adopt solenoid valve, and whole transfer process can be controlled automatically.
Container has two in this device, and the one, density bottle, the 2nd, aerosol bottle.The physical dimension relative fixed of density bottle is guaranteed the centering installation of density bottle and interface valve and is fixed the open and close of interface valve by design effort platform, mechanical micro-adjusting mechanism and hold down gag.Key is, tested aerosol jar physical dimension differs, and has only after forming negative pressure in the density bottle, could advance and open the interface valve, and this is a dynamic process.Here the centering that has interface, the rectilinearity of progradation, the problems such as control of advance distance and propelling power.The interface interface can not in and progradation straight line not, may cause content to leak, the serious damage that causes the sample nozzle.The bad valve that may cause of the control of advance distance and propelling power is not opened, or overexertion makes the valve distortion, damages.
In the utility model, the propulsion system that design is made up of motion-control module (stepper motor), rail plate, mounting platform and cylindrical adjustment ring etc.Because the stroke of opening fully of aerosol valve only is about 5mm, the height of whole aerosol bottle is at 178mm-280mm, so moving guide rail is selected the RCP2-SA7C type slide block of IAI company for use, its helical pitch 4mm, range 100mm, maximum translational speed is 120mm/s, and maximum horizontal carrying quality is 40kg, repetitive positioning accuracy ± 0.02mm.Motion-control module (stepper motor), step rate 1pps～250kpps; Maximum number of steps: the 232-1 step; The output pulse mode: clockwise/inhour; Simultaneously according to characteristics such as the controllability of stepper motor operation and adjustables, by stepper motor step-length control air line distance is set, the native system design be every 4mm process, the output of pulse is 800, meet fully this device apart from control accuracy.By the torque limit parameter of stepper motor, the control propelling power surpasses the protection value when motor promotes moment of torsion, and the motor stopping alarm prevents overload, protective device.
As required, design slide block fltting speed is 30mm/s, retreats to be 10mm/s.These measures can realize quick operation, accurately to the pinpoint requirement that neutralizes.
Adopt the utility model to family expenses aerosol commodity amount metering test method, at first aerosol content is transferred to density bottle, in the transfer process with the negative pressure of vacuum pump and extraction valve control density bottle :-90kPa～-95kPa, and discharge with the content of introduction valve control aerosol; Use relative density method formula then:
Calculate the quality of tested aerosol content.
Since pressure property and container contents non-singularity in aerosol products has, and under the decompression situation, can not keep original form, and this just makes us can not detect its volume with the method for routine.At this problem, the main target that this project will be studied is that content with test product is under the condition that does not change its form, be transferred to us by reasonable manner and can observe in the container (instrument) of disposal, under the environment provided condition, carry out volume with relative density method or absolute density method and detect.This method also should be applicable to the batch pattern detection and have reliable and stable performance.(being called for short the capacity transformation approach).
This method of inspection is to guarantee that the content of aerosol products is constant in form, shifts under the prerequisite that quality is not lost.According to the purpose that will reach, should consider during the design apparatus scheme guaranteeing that transfer process is controlled under the prerequisite that the sample content does not does not scatter and disappear that testing result can be reviewed.Pick-up unit is made up of topworks and control section.
In order to keep also consistent with the detection method of 1070 regulations with the detection principle of present aerosol correlation standard as far as possible, device is based on the relative density method, refers to the density principle design consistent with the density of the content that is transferred out of sample content here.
