The operation principle of this utility model semi-automatic canister control valve flow testing device is:
Canister control valve test is divided into two steps.First step regulates machine by flow rate test
Structure carries out Flow-rate adjustment, and second step carries out flow rate test by flow rate test mechanism.
Flow-rate adjustment step is subdivided into two important links, flow rate test governor motion and flow
The method controlled.Flow rate test governor motion is by using the first lift cylinder 2, regulation cylinder
3 and reset power-assisted cylinder 4 complete the elevating control of set screw cutter 1.Motor 5 is driven to realize
Accurate regulation to canister control valve flow.First lift cylinder 2 is responsible for crane 6 and is lifted.
Regulation cylinder 3 is responsible for the regulation lifting of set screw cutter 1.Reset power-assisted cylinder 4 is responsible for spiral shell
Silk cutter 1 departs from canister control valve to be measured.Motor 5 is driven to be responsible for by belt gear 8 right
Canister control valve is adjusted.
Owing to the first lift cylinder 2 area is big, therefore whole flow rate test can be regulated by thrust
Mechanism is upwards pushed into the height being closer to canister control valve.Then to employ thrust less in design
Set screw cutter 1 is pushed in canister control valve to be measured by regulation cylinder 3.This is it is achieved that big
The motion of stroke, but use less power when of contact measured canister control valve, to prevent
Wound product.Hydraulic cushion is increased when mechanism finally touches the position of canister control valve to be measured
Device 12.Adopt can reduce further in this way and treat the impact surveying canister control valve.
Motor 5 is driven to use servomotor to carry out Accurate Position Control.According to current real-time flows amount
Value, calculates the anglec of rotation.Complete regulation.During regulation, use belt gear 8
The power driving motor 5 to rotate is sent on the cutter head of screwdriver 1.
By PLC timing acquiring current atmospheric pressure and ambient temperature, the cycle of collection
Be 2 hours once.Through formula scales, it is standard by the data reduction of flowmeter survey
The flow of operating mode.The when that set screw cutter 1 regulating canister control valve 10 to be measured, according to
Situation when canister control valve 10 works provides pulse signal, and is adjusted.The present embodiment
Be for a product be regulation time, provide 10Hz pulse signal, dutycycle is 70%.
Its control mode is as shown in Figure 3.
Pressure and flow can produce periodically shake along with the pulse signal that equipment provides.For
Elimination this shake.Design uses wave filter to carry out smothing filtering.Gather in a control program
The data of 100 points of continuous print, do smothing filtering.This can obtain metastable data.
The method judging pressure and stability of flow, employs two important scopes:
Whether current data (pressure or flow) is in rational scope；
Two passing data slope calculations, whether slope is less than setting value；
First data, it is ensured that current pressure or flow are in correct scope of data.
Second parameter ensures pressure and flow, does not the most rise or declines.Data are the most steady
Fixed.
Second step is the checking that regulation screwdriver 1 regulates result.Canister control valve to be measured
After overregulating, demand may be met under running conditions.But in order to prevent working environment from becoming
After change, properties of product are unstable.Need product is verified again.Checking method be
Under different duty cycle pulse signal, identical pressure, whether flow becomes being still in correspondence
Zone of reasonableness in.After there is data on flows the most in the reasonable scope, PLC controls
System can retest again, repeats three times.If three tests are all failed, then judge
There are quality problems in workpiece.
Flow rate test mechanism in this utility model semi-automatic canister control valve flow testing device
For testing the flow direction of valve body it is, from bottom to top, direction from left to right.
It is to connect canister control valve joint 21 to be measured in bottom.There is an Instrument for Pressure top
Table 22, for detecting whether canister control valve 10 to be measured is in stable pressure state.
Flow rate test valve 23: when needs carry out testing canister control valve 10, this vacuum valve can be beaten
Open.Gas will flow into from canister control valve 10 direction.
When not having canister control valve 10 to be measured, flow rate test valve 23 cuts out.Pressure maintenance valve
24 open.At this moment can ensure that the pressure that in pipeline, postal is stable.When needs are tested
Waiting, pressure maintenance valve 24 is closed.So can reduce the pressure loss.Quickly from standby mode
Be converted to test pattern.
Mid portion is two dust filter units.Left side is metallic dust filter 25, this powder
Dirt filter comprises Magnet.Magnet metallic dust in adsorption production.Right side is air
Dust filter unit 26 is used in filtering product assembling process plastics or other dust left over.
Effusion meter 27 is for testing the real gas flow of canister control valve 10.
Vacuum breaker 28 and Instrument for Pressure 22 table constitute a pid control circuit.PLC is responsible for
Realize PID control.Ensureing in the joint connecting product, pressure is in one in real time and determines
The negative pressure test condition of-700mbar ± 20.
The above is only preferred implementation of the present utility model, it is noted that for this skill
For the those of ordinary skill in art field, in the premise without departing from this utility model know-why
Under, it is also possible to making some improvements and modifications, it is new that these improvements and modifications also should be regarded as this practicality
The protection domain of type.
