When repairing threshold value, that is, judge that needs are overhauled.
When maintenance identifying unit 240 is judged to needing maintenance, control unit just controls alarm unit 250 to alarm,
Prompting is overhauled.
Control unit 260 is used to be controlled.
The principle of two way seal：
In use, the first actuator first and the action of the second actuator, complete sealing.The cylinder driving of first actuator is double
After being inserted into sealing-plug in the opening of pipe piece, the gas in cylinder loses heart, and actuator is due to losing driving force in main plug
It can retract under the action of the elastic recoil power of body, retract to drive at this time and strengthen sealing ring retrogressing, since stiffening ring is with inclining
Oblique side wall has the angle of 20 degree of degree, once retracting, it is closer make it that reinforcement sealing ring engages with the inner wall of pipe piece, into
One step strengthens sealing function, that is to say, that in insertion, is sealed by main cock body, in rebound by reinforcement sealing ring
Sealed, i.e. two way seal.
, can cladding O shape springs, further reinforcement in elastic pole ring 233 as further optimization design
The effect of sealing.
The effect of embodiment
Assembling integrated machine system according to involved by the present embodiment, because assembling integrative machine has pair for sealing
There is the main cock body for sealing to sealing-plug, and be arranged on the reinforcement sealing ring that main cock body is entangled on main cock body, and strengthen
Angle between the side wall of sealing ring and main cock body is 5-30 degree, so equivalent to there is two sealings：The first sealing of main cock body
And strengthen the secondary seal of sealing ring, when particularly there is poor sealing because of abrasion when main cock body, secondary seal adds
Strong sealing ring will carry out supplement sealing.
Again because it is that the angle being sleeved on the side wall of main cock body and between side wall is 5-30 degree to strengthen sealing ring, further
When in use, after when in the opening for being inserted into pipe piece, actuator is due to losing elastic recoil of the driving force in main cock body
Raw rollback is postbacked under the action of power, retracts to drive at this time and strengthens sealing ring retrogressing, due to the angle of this 5-30 degree, can cause
Strengthen sealing ring and engage with the inner wall of pipe piece closer, further strengthen sealing function.
Because the sealing performance that the sealing unit of external pressure source is introduced during test stabilizes, the pressure change of test
Situation gets over the sealing performance that can reflect pipeline connection, and due to the structure design of secondary seal so that test result can
It is more stable.
Again because can be judged according to pre-defined rule air pressure-time data with control device, according to structure come
Judge whether the sealing performance of pipe piece is qualified, that is, realizes the judgement of automatic-sealed performance, save manually, improve effect
Power.
In addition, because strengthening being coated with elastic sheet metal in sealing ring, elasticity can be strengthened, such design can make
It must strengthen sealing ring and obtain stronger sealing effect, and can also be supplemented even if abrasion by elastic-restoring force, be avoided close
Seal undesirable generation.
Further, because maintenance identifying unit can carry out air pressure-time data of this survey and the data of last time
Compare, when the difference of two groups of data exceedes maintenance threshold value, that is, judge that needs are overhauled, so as to the master when occurring abnormal
Dynamic find, active warning is safeguarded, ensures the stability and accuracy of testing result.
The above embodiment is the preferred case of the present invention, is not intended to limit protection scope of the present invention.
