Air-tightness, including clamping unit 10, installation unit (not shown), inflation unit 20 and sealing are detected with gas source connection
Unit 30.
Clamping unit 10, as shown in Figure 1, having the groove to match with pipe piece, pipe piece A to be detected is by machine
Tool hand, which is placed into groove, to be fixed.
Installation unit (not shown), is arranged on the rack, including manipulator, which puts corresponding sealing element
The corresponding position for setting pipe piece is sealed.
Fig. 3 is the schematic diagram of the two way seal plug and pipe piece sealing in the embodiment of the present invention.
Inflation unit 20, for one end of pipe piece inflate, as shown in Figure 1, 2, including the first actuator 21, with should
The inflation hard tube 22 that actuator 21 connects and the two way seal plug 23 being mounted on the inflation hard tube.
First actuator 21 is used to that inflation hard tube 22 and two way seal plug 23 to be driven to carry out the reciprocating motion of straight line, Ke Yiwei
Electromagnetism part or pneumatic cylinder, hydraulic cylinder, are used in this embodiment pneumatic cylinder.
Inflate hard tube 22, one end and the connection of the first actuator 21, lumen and extraneous high-pressure air source B are connected to, be used for to
Inflation in the pipe piece of test.
Two way seal plug 23 includes main cock body 231, reinforces sealing ring 232 and elastic pole ring 233.
Main cock body 231, for the rubber bodies of elasticity, in a circular table shape, one end close to pipe piece is small, and the other end is big,
Open at one end with pipe piece matches, and the inside callipers of different pipe pieces is adapted to and filling in the difference of depth
Lattice.There is the through-hole passed through for inflation hard tube 22 on main cock body 231.
Reinforce 232 sets of sealing ring on the sloped sidewall of main cock body, inner ring is connect with sloped sidewall, is connected to side wall
At 1/4 to 3/4 position, the angle between sloped sidewall is 5-30 degree, and the present embodiment is at 1/2 position, and angle is 20 degree.
Elastic pole ring 233 is the ring that the pole of diameter 2-8mm is linked to be, is arranged on the outer ring for reinforcing sealing ring 232.
In the present embodiment, above-mentioned main cock body 231, reinforcement sealing ring 232, elastic pole ring 233 are integrally formed.
In the present embodiment, in order to further strengthen elasticity, reinforce being coated with elastic sheet metal in sealing ring, which can
To be muti-piece, it is also possible to the smaller sheet metal identical with sealing ring 232 is reinforced of shape.
Sealing unit 30, for blocking the other end and the sealing of pipe piece, including for measuring the gas in pipe piece
The barometer of pressure, the second actuator, the sealing-plug being connect with second actuator.Second actuator is for driving sealing-plug to carry out
The reciprocating motion of straight line can be electromagnetism part or pneumatic cylinder, hydraulic cylinder, pneumatic cylinder is used in this embodiment.
Fig. 4 is the module diagram of the control device in the embodiment of the present invention.
As shown in figure 4, control device 200 includes switch unit 210, data acquisition unit 220, judging unit 230, maintenance
Judging unit 240, alarm unit 250 and control unit 260.
Switch unit 210, setting is on inflation hard tube, for controlling the opening and closing of inflation hard tube and inflation, pumping state, tool
Body is exactly a valve, by connecting from different gas sources or negative pressure source come the conversion for the state for being inflated, being evacuated.
Data acquisition unit 220 is connect for recording air pressure-time data with barometer.
Judging unit 230 judges air pressure-time data according to pre-defined rule, is judged to manage according to judging result
Whether the sealing performance of road part is qualified, in this example example, exactly judges whether pressure variety in the given time is greater than
Otherwise predetermined value is determined as qualification if it does, deciding that the sealing performance of the pipe piece is unqualified.
Control unit 260 adds up the item number of the record data of data acquisition unit 220, when detect data acquire
When the data times of collection of unit reaches pre-determined number, just after completing the secondary data acquisition, control switch unit 210 is opened
It closes and is evacuated, after pumping, just the first actuator 21 of the control movement of control unit 260 measures air pressure-time again
Data,
The data will be compared with the data of last time for maintenance judging unit 240, when the difference of two groups of data is more than inspection
When repairing threshold value, that is, determine to be overhauled.
When maintenance judging unit 240 is judged to needing to overhaul, control unit just controls alarm unit 250 and alarms,
Prompting is overhauled.
Control unit 260 is for being controlled.
The principle of two way seal:
In use, the first actuator first and the movement of the second actuator, complete sealing.The cylinder driving of first actuator is double
After being inserted into the opening of pipe piece to sealing-plug, 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 will drive at this time reinforces sealing ring retrogressing, due to reinforcing sealing ring
There is the angle of 20 degree of degree with sloped sidewall, once retracting, reinforcement sealing ring can be made to engage with the inner wall of pipe piece tighter
It is close, further strengthen sealing function, that is to say, that in insertion, it is sealed by main cock body, it is close by reinforcing in rebound
Seal is sealed, i.e. two way seal.
As further optimization design, O shape spring can be coated in elastic pole ring 233, it is further to reinforce
The effect of sealing.
The action and effect of embodiment
Integrated machine system is assembled according to involved in the present embodiment, because assembly integrative machine has for the double of sealing
There is the main cock body for sealing to sealing-plug, and the reinforcement sealing ring for entangling main cock body on main cock body is set, and reinforce
Angle between sealing ring and the side wall of main cock body is 5-30 degree, so being equivalent to, there are two sealings: the first sealing of main cock body
And reinforce the secondary seal of sealing ring, when especially there is poor sealing because of abrasion when main cock body, secondary seal adds
Strong sealing ring just will do it supplement sealing.
Again because it is 5-30 degree that reinforcement sealing ring, which is the angle covered on the side wall of main cock body and between side wall, further
When in use, after when in the opening for being inserted into pipe piece, actuator is due to losing driving force in the elastic recoil of main cock body
Raw rollback is postbacked under the action of power, retract will drive at this time reinforces sealing ring retrogressing, due to the angle of this 5-30 degree, can make
Reinforce sealing ring and engage with the inner wall of pipe piece closer, further strengthens sealing function.
Because the sealing performance for introducing the sealing unit of external pressure source when test stabilizes, the pressure change of test
Situation gets over the sealing performance that can reflect pipeline connection, and since the structure of secondary seal designs, so that test result can
It is more stable.
Again because have control device air pressure-time data can be judged according to pre-defined rule, according to structure come
Judge whether the sealing performance of pipe piece is qualified, that is, realizes the judgement of automatic-sealed performance, saves manually, improve effect
Power.
In addition, because elasticity can be reinforced, such design can make reinforcing being coated with elastic sheet metal in sealing ring
It must reinforce sealing ring and obtain stronger sealing effect, and can be supplemented by elastic-restoring force abrasion, be avoided close
Seal undesirable generation.
Further, because maintenance judging unit can carry out the air pressure-time data and the data of last time that this is surveyed
It compares, when the difference of two groups of data is more than maintenance threshold value, that is, determines to be overhauled, so as to the master when occurring abnormal
Dynamic discovery, active warning are safeguarded, guarantee the stability and accuracy of testing result.
Above embodiment is preferred case of the invention, the protection scope being not intended to limit the invention.
